Sacred Institute – Act II (3)

III. The service starts

The next morning, sister Riley sits nervously on the bed, looking at a countdown on a display, counting down the seconds until 9 o’clock. When the door opens, the master sees a girl with a scared look on her face.

“There she is! I’ve been waiting quite some time to see you. A fresh external sister, what a rare sight!”

“Good morning … master”

He probes her new body, while she sits scared stiff on the edge of her bed.

“Very impressive work, just like in the photos. And you were not born in the institute. Have you been to school?”

“Yes, master.”

“Let’s see … which president was assassinated in 1963?”

“Uhhhhh … John F. Kennedy?”

“Who came up with the equatiion that E equals mc2?”

“Wasn’t that Einstein?”

“What is the best football team?”

She weakly raises her hands with a smirk.

“How ‘Bout Them Cowboys?”

The master mockingly also raises his hands for a moment and laughs.

“That is great, you were born out there in the real world, loved by a mother, raised by teachers, taught that you can be anything you want. And now you are here, against your will, getting fucked forever. I love that this is possible, that it is purchasable. Now, how about you go suck my cock, slave?”

Her smirk has turned into a sad expression. After all that circus, it still comes down to what she had to expect, but didn’t want to become a reality. Still, she crawls between his legs and starts blowing her first master.

After having seen only giant cocks the last day, the master’s dick barely poses a challenge. Once he is hard, he tells her to kneel on the bed, where he takes her ass for a ride. Sister Riley is surprised how easily she can take his entire dick in her ass. Even when he is thrusting with all his might, she is far from being pushed to her limit.

However, even more bewildering it is when she notices that she has been moaning for quite some time. While the brothers yesterday were admittedly handsome, her master is not very attractive. Yet, she seems to enjoy getting her ass fucked, at least a bit. While she can hear the out-of-shape man behind her wheezing, trying to pound her, she is secretly thankful for having her ass stretched in advance and the drugs that make her so aroused.

Once he is out of breath, he lays on his back and makes her ride his cock in the cowgirl position. Both of them are surprised to see that her cock had grown stiff and now slaps her master’s fat belly with every jump. The master is both disappointed and excited about her arousal and props her up to lie on the back of her head, with her cock pointing at her mouth while he keeps drilling in her ass.

“Jerk yourself off, come in your mouth while I’m fucking your ass.”

She reaches for her cock and starts to massage it, starting from small movements, transitioning to frantic masturbation. In her uncomfortable pose, she struggles to breathe, while her master keeps pumping into her ass. However, her body eventually responds to the stimulation and she can slowly feel an orgasm building up inside of her. She is too embarrassed to admit that she is about to cum while getting fucked by that weird man, but her wide-open eyes and faster breathing give her away. She stops herself from encouraging her master to fuck harder and instead slowly whimpers that she is about to come.

Seconds later, the man towering over her is laughing in awe when her cock starts blasting an inch away from her lips. While her orgasm dies down, the master gets off the bed, pulls her to the edge of the bed, grabs her cock and starts thrusting. Her dick is still sensitive to the firm grip and she tries to touch his hand, but he slaps it away.

“Don’t stop me, that is the best part. Unlike the other slaves, you do have a refractory period, your dick is sore and sensitive, and your horniness has subsided. For a moment, you are uncomfortable and vulnerable. I like to see you struggle.”

He speeds up as he hears her groans getting louder and stroking her cock faster even rewards him with a short scream of agony. After a minute of jackhammering her, he finally pulls out and raises her up so she can suck him to completion. In this short duration of reduced horniness, she notices how much more difficult it is for her to lick a dick that just came out of her ass. But she does not dare fail at the last seconds. Once his balls are drained, the master falls into a chair with a blissful smile on his face.

“I have been waiting for months to fuck you. The day I heard that they have a new external sister, I booked the first possible slot. It cost me a lot, but you were worth it.”

Sister Riley sits embarrassed on the bed with her arms around her pulled up legs. Not knowing what to say, but thinking she has to reply, she musters a silent ‘thanks’. The man seems to not care and eventually leaves her chamber. Since the display on the wall tells her to clean herself, she takes a quick shower and takes her place on the bed, waiting for her next master.

The next two men handled her similarly. Afterwards, she received a mistress, who seemed hell bent to stuff as many toys into her as possible. The last master before lunch wanted to be fucked by her, which gave her ass a break, but was physically exhausting with her weak body. Her lunch was full with high-fiber ingredients, which were not the tastiest, but she welcomed food that would keep her bowels clean if she had to suck off every man drilling in her ass.

The afternoon went similarly, but she gradually struggled to make herself cum and even to stay hard with her last master of the day.

After he left her chamber satisfied as well, she is lying exhausted in the bed, when, to her surprise, father John comes into her chamber, in order to review the day.

“Every master was very pleased with you. You were struggling at the end, but eventually you will get better, so I don’t think I’ll have to worry about that.”

“It is exhausting to fuck the entire day, father John. I don’t know if I can keep it up.”

“You will have to.”

Sister Riley does not look happy with that answer, but sighs after a short pause.

“Do you have any advice to make it easier?”

“Much to the chagrin of our clients, it will become easier automatically, that is, if you keep training.”

“Train what, father John.”

“Exercise your body at the end of the day, stretch your ass, stretch your cock, fuck as much as possible, and come as much as possible.”

“I hate to admit it, but those drugs that make me horny, they help a lot to get me through the day. Can you increase the dosage?”

“No, our clients don’t want it to be too easy for you, just enough to function. A higher dosage is a reward to be earned.”

“How? How can I earn these rewards, father John?”

“It is too early for you to think about that. You need to prove yourself first. It has not even been a week. I only give you advice, because you have been a good girl.”

She looks at him with her sad big eyes.

“Like I promised.”

After a pause of silence, he tells her to train and leaves her alone again.

The next few days, sister Riley wakes up with sore muscles on her long journey to build back her muscle mass. She still dutifully serves every master to the best of her capabilities. The initial shock of being forced to have sex wears off and she falls into a routine of fucking whatever comes through the door, albeit largely facilitated by the drugs, which increase her arousal high enough for her to fuck anything.

After two weeks, the clueless girl is brought to a room for a few medical exams. Afterwards, father John comes in reading papers with test results.

“Your blood work looks fine and hormone levels are where they are supposed to be, which means we can continue your medication. And your brain structure continues to shift.”

Sister Riley has a worried look on her face.

“Shift whereto, father John?”

“Towards a female brain, but only partly. We usually land somewhere in between. We also aim to increase activities in areas of your prefrontal cortex that controls inhibition, in particular your anterolateral prefrontal cortex. As a result, your sexual inhibition should permanently decrease.”

“which means … ?”

“… increased sexual attraction and arousal.”

“It worries me that you mess with my head, father John.”

“Nonsense. Firstly, it makes it easier for you to serve masters, which you had concluded yourself already. And secondly, you don’t have a choice. Since you can’t change the outcome, there is no need to worry.”

While she can’t argue with his logic, she does not find a lot of comfort in his answer. But she loses her thought, when she notices him wrapping something around her neck. In a mirror she can see that she is now wearing a blue ribbon, resulting in a confused look at father John.

“You have now served a hundred masters, which indicates that you have integrated yourself well in the institute.”

“I didn’t know I had to meet a goal, father John.”

“It also indicates that you appear to be safe for masters. If you knew, your intention would not have been properly tested. The blue color indicates that you are level 3, which tells our clients that you can take in the ass a circumference of 19 cm (7.5 inches), a flexible depth of 22cm (8.7 inches) and a rigid depth of 20 cm (7.9 inches).”

“I can already take more than that, father John.”

“But not enough for level 4, which is a circumference of 24 cm (9.4 inches), a flexible depth of 35 cm (13.8 inches) and a rigid depth of 25 cm (9.8 inches).”

Sister Riley shakes her head, being humbled by these numbers.

“I take it that your nipples have become a lot more sensitive.”

She blushes with a shocked expression and avoids his eyes with embarrassment.

“Yes … a lot. How did you know?”

“I saw that you have been playing with them many times. But that is good, it means nipple piercings will be more effective.”

She immediately looks back at him with a wary and questioning stare, which turns to a pleading expression when he pulls out a needle.

Unconcerned with her pleading and eventual screaming, he proceeds until a ring is hanging off each nipple. Father John smiles surprised when he hears her cursing out the pain, as he momentarily forgot that external sisters do know how to swear. But he lets her blow out some steam, knowing that she needs to endure a bit more. Once she has calmed down, he explains that he will now expand her breast implants.

She has a terrified look on her face, when father John approaches her with a large syringe, which he inserts into one of her tits. She can see and feel it expand, while he keeps pressing down the piston of the syringe. When the second one is growing, she can’t suppress her screams of panic. After he is done, she is breathing heavily, trying to process what just happened.

“They have been doubled in size from 500cc to 1000cc. You will feel a bit of tension the next couple of days, but that will eventually go away. Now come, we will go to your new chamber.”

While they are walking there, she is still feeling her new breasts with her hands, probing their round shape and her hurting nipples. Only when they are in her new room does she realize that she is moving into a larger chamber with a larger bed and nicer furniture. The most excited she is about her new music player, even though a music ***********ion limited to classical music disappoints her a bit. He reminds her that her overall schedule stays the same. When he is gone, she gets to examine her room for a bit while Bach’s Goldberg Variations are playing in the background. However, the display soon after prompts her to start her physical training. In the evening, she puts in more effort when stretching her ass, as she is curious about level 4.

On the next day, she receives her first master and swallows his load after taking him in the ass for a while. After catching his breath, he sits down in a chair and requests on his phone to let someone in.

Soon after, the door opens and another sister comes in, politely asking her master what she can do for him. He laughs when he sees sister Riley’s jaw drop at the sight of her beauty. She has never seen a woman with such a perfect body and angelic face, making her feel both ugly and aroused.

“Hehe, what a marvelous piece of ass, right? I assume that this is the first time you see a sister with a pussy, which is funny as that is most of them. Honey, what’s your name?”

“Sister Simone, master.”

The master beckons her and points at his groin, whereupon she kneels between his legs and starts blowing him. Sister Riley can’t help but stare at her ass, which the master notices with a grin.

“So enticing, hehehe. Their holes are so tight and soft at the same time. You wanna try?”

“Fuck, yeah, please master, let me have a go.”

After a smiling nod of approval, she jumps off the bed and inserts her rock-hard cock into sister Simone’s pussy. It is incredible. She does not only look gorgeous on the outside, she feels amazing on the inside. How can a pussy feel so much better than all the other pussies? The master laughs again when he sees sister Riley shaking her head in disbelief while thrusting inside her new favorite pussy. After a while, she tries out that great ass as well, but not long after, she announces that she is coming. Sister Simone swiftly turns around and gulps down the cum exploding from her dick. While sister Riley sits down to recuperate from the wonderful experience, the master keeps talking.

“Yeah those tiny fuckholes can snuggle tightly around your dick, but they can also take bigger objects. Push your fist in her pussy.”

Sister Riley crawls back behind sister Simone and lifts her right fist with a dumbfounded look at the master. When he nods, she shrugs and carefully probes with her fingers, gradually inserting more and more. Sister Simone keeps sucking unperturbed, except for a tiny moan when the fist fully slides inside.

“And now your other fist at the same time in her ass.”

Sister Riley marvels at the sphincter gradually opening around her fingers and eventually swallowing up the entire fist. This time, sister Simone is moaning a lot more, but does not lose focus on pleasing her master, who is rock hard again. Sister Riley is then instructed to thrust until the girl comes, but she needs several attempts to figure out how to move. When she momentarily loses her balance, she instinctively tries to support herself on her arms, accidentally pushing deep into the groaning girl’s guts.

Eventually, sister Riley finds a movement that resonates with sister Simone, causing her breathing to intensify, moaning onto her master’s cock, until they both come at the same time. After they both have calmed down, sister Riley carefully retrieves her fists from the beautiful creature, who squirms out one more time, when the fists are naively pulled out at the same time. Sister Riley looks at the master with excitement and wonder and he smiles back.

“Awesome, right? Ok, but now it is your turn. Get down on all four. Sister Simone, lube up your hand, it is her first time.”

The smile on Sister Riley’s face has turned into a worried look.

“What? I can’t do that, that is some high level magic, but I have never done that. Nobody told me I had to do that, master.”

“Hehehe, I paid father John to let me tell you instead, so I can see your face when you hear and it was so worth it. But I’m not lying. Sister Simone, truthfully, at what level is fisting by a woman allowed?”

“From level 3 on, master.”

“You see? That blue ribbon on your neck means that her fist will go up your ass. And I bet you were curious about it while poking in her guts.”

Sister Riley shakes her head at first, but then stares at the woman and slowly starts to smile subconsciously. The master enjoys reading her face, as she gradually accepts her fate. At the end she looks back at him and shrugs.

“Ah, fuck it, I can’t say no to those pretty eyes of yours … or to the girl. It’s not up to me anyway.”

“Hehehehe, fucking hell, what a character, I like it.”

She crawls on the bed with her ass at the edge of the bed. Sister Simone gently probes around the anus and carefully inserts her middle finger into the still tense girl. However, after some time she can relax and more and more fingers can be added. Once the tips of all fingers are inside, she pushes harder, until the sphincter struggles with the width at the knuckles. Sister Riley’s breathing has turned into loud groaning with her head buried in the bed.

“Fuuuck, just a second please… it might be possible, but I can’t go that fast. I’m trying, give me a moment …”

After some deep breaths, she nods and braces herself, while sister Simone pivots her hand at various angles and applies more and more force. Sister Riley screams muffled groans into the bed but keeps pressing her ass backwards until the fist pops inside. She lifts her head with a dazed look and checks behind herself if she truly made it. Sister Simone winks at her with a smile and keeps probing deeper while maintaining eye contact. At a depth of around 24 cm, sister Riley has to stop her, at which point, she checks inside the mirror at the wall, admiring her achievement. The master instructs her to lay on her back so sister Simone can start jerking her off, which she initially enjoys until she notices her ass clenching the arm inside.

“Wait, I don’t know if I can handle the arm in my ass if I come. Can she pull it out first, master?”

“No, the arm stays inside.”

“What if I try not to come, master?”

“Hehehehe, you hear how little faith she has in you, sister Simone? Make her eat her own words.”

Sister Simone smiles and starts blowing her, causing sister Riley to curse out the amazing sensation she is provided. It takes less than 5 minutes until she explodes into her mouth. Once the great feeling on her cock fades, her strained ass becomes more and more uncomfortable. But the master orders the arm to stay inside, while he fucks sister Simone, every thrust pressing deep into sister Riley’s ass. Once he comes a final time, the sister withdraws and leaves sister Riley’s chamber with the masters.

In the next few days, she has to take a lot more fists up her ass, either from sisters, single mistresses or even from a wife of a married couple.

She now also encounters trans sisters from the institute, who sport massive 30 cm (11.8 inches) cocks that are too long to fit in her ass yet.

Seeing how much she will have to take, she keeps stretching every morning and evening, in order to take wider and deeper toys and cocks in her ass. As a result, she can already take fists of the trans sisters, who have slightly larger hands, pushing her again to her limit.

After three months, she finally passes the requirements for level 4, when she is able to take a circumference of 24 cm (9.4 inches), a soft depth of 35 cm (19.6 inches) and a stiff depth of 25 cm (9.8 inches). Father John expands her implants to a total of 1500cc each and replaces her blue ribbon with a purple one.

After they reach her new chamber, he explains to her that she now gets to *********** her food once a week and that her music ***********ion is expanded to music up to the romantic era and plays the waltz of flowers by Tchaikovsky. Sister Riley seems not impressed by the ***********ion of music, but is much more excited to hear that her dosage will now be increased by 10%.

Her excitement is dampened when he announces that men are now allowed to fist her as well, which is promptly demonstrated with the fist of father John himself. For her, it is a difference like night and day. While the fists of women were soft, pliable and sleek, father John’s fist feels edged and tight. It seems like a cube stuck to a log is driven into her ass. Once inside, he tries to push deeper, but her rectum is not ready yet. With his fist still in her ass, they walk over to her cupboard, where he shows her toys that will help her stretch for depth and size. She tries to listen carefully and take the advice to heart, but has trouble paying attention with her ass stretched that much. Eventually, she agrees to use a tapered and cylindrical dildo, until he finally pulls his fist out of her and replaces them with the two toys. Before he leaves, he mentions that masters can now also piss in her ass. The last few bars of the waltz of flowers play while she stands alone in her new chamber with a gaping ass and two huge dildos in her ass.

The next morning, she is brought to the chambers of another sister, where she is greeted by a group of eight masters, who introduce her to sister Veronica. Sister Riley does not pass the chance to fuck the beautiful girl and make her swallow her load. Shortly after, the masters join in for a gangbang, wherein the girls drain the balls of each one of them at least once.

Once everyone caught their breath, sister Riley has to lie face down on a table with her cock through a hole, which is subsequently tightened, strapping her down. In that position, she has to suck her masters hard again while also getting fisted in the ass by masters that are waiting their turn. The other girl is sitting under the table and has to make sister Riley come. Since she came just a few minutes before, she has to take many fists, until she finally manages to blast another load down sister Veronica’s throat.

The masters give her a short break, in which they explain that today’s game involves three stages and that she just finished the first stage by coming into the girl’s mouth below the table.

In the next stage, one of the masters starts fucking her ass. Sister Riley is first relived as that is a lot easier to take than a fist. But her eyes widen in shock, when he starts pissing in her ass. While sister Veronica attempts to make the cock through the hole hard again, sister Riley has to suck off her master’s cock coming fresh out of her ass. By the time he shoots his second load down the girl’s throat, another man already started pissing in her ass. She struggles to tend to the cock in her mouth, while clenching her ass tight enough to not spill anything, making it almost impossible to focus on her cock getting sucked. After the fourth master emptied his bladder, sister Riley is hard again, but her full ass makes it difficult to relax.

“Please masters, I’m trying to come, but my ass is full and distracting, I can’t take anymore.”

“You hear this, sister Veronica? It seems that you are failing your challenge. What are you going to do about that?”

When she crawls out under the table, she is wearing weights on her nipple piercings and looks worried over to sister Riley, who is confused about what is happening.

“Why are there weights on her tits? What is going on, sister Veronika?”

The masters chuckle and one of them explains.

“Every 5 minutes, weights are added until the end of the third stage. So, she has to make sure that you come as fast as possible.”

Slowly, she starts to realize that this game and its punishment are not about her, but about sister Veronika. She was clueless about the suffering of the girl below her.

“I’m sorry, sister Veronika, you are doing a great job, but I’m struggling over here.”

But the girl gently caresses sister Riley’s head and calmly comforts her in her tender voice.

“You don’t have to worry about anything, sister Riley. It is up to me and not up to you.”

She smiles and walks to the backside of the bed. Sister Riley can only hear the dangling of the weights and after a short pause, she can feel lips against her ass. The crowd starts cheering when sister Veronica is sucking the piss out of the tied down girl, who is apologizing profusely.

“No, that’s not what I meant. I’m so sorry, you don’t have to do this … but I cleaned it out before, I promise … I’m sorry …”

Once she is done, she walks over to the other end of the bed, crouches down and kisses sister Riley gently on the lips.

“You are so sweet and innocent. This is not the first time I did this. I’m used to it, don’t worry. Now be a good girl and come in my mouth.”

“… ok … sorry still…”

Three more masters empty their bladder into sister Riley’s guts, until she manages to come her third time into sister Veronika’s mouth. Afterwards, she still empties sister Riley’s backside and even lets the last master piss right down her throat. Sister Riley is stunned looking at the girl with tons of weights hanging from her tits, standing with a smile amongst the masters cheering at her efforts. But she is also worried about herself, when she fees that is hard again. Oh god, what have they awakened in her? Does she like watching girls drinking piss?

In the last stage, the masters simply fuck sister Riley’s ass and make sure to dump their cum in her mouth. Despite getting hard fairly quickly, it takes another half an hour of ass pounding until she can finally pump her last load into the girl below.

Sister Riley is released from the table and carefully sits up, holding her sore cock. She is surprised, seeing that sister Veronica has 16 weights hanging from her tits, obviously causing her a lot of pain. But the disciplined girl does not even touch them and instead awaits her next instructions. The masters tell her to fuck herself on their cocks, while wearing the weights, wherein each load she manages to get out of them, allows her to remove one of her weights.

Sister Riley is told to leave, having fulfilled her purpose. However, she asks if she can somehow help the girl that is already riding two of her masters with bouncing tits and weights. Everyone, including sister Veronica, seems baffled by the offer, but they accept and transfer two weights over to the nipple piercings of sister Riley.

It hurts more than she expected and she cannot fathom what it must feel like for sister Veronica to bounce many times more that weight on her breasts. Despite her sore ass, sister Riley dutifully takes one of her masters in the back, while sucking another one off. After swallowing both their loads, she is eventually kicked out of the chamber, but sister Veronica still manages to shout a ‘thank you’ at the helpful girl. They exchange a short smile and sister Riley is brought back to her own chamber.

Back in her room, she is reflecting on the event. These pureblood sisters truly are on a different level. So much more capable and dutiful, whereas sister Riley’s main purpose was to handicap sister Veronika through her incompetence. And despite the torment that was caused, she was forgiving and thoughtful. The least she can do is try to get better.

Sister Riley keeps stretching her ass and four months later, she meets the requirements for level 5. Her ass can now handle a circumference of 28 cm (11 inches), a flexible depth of 50 cm (19.7 inches) and a rigid depth of 30 cm (11.8 inches). Father John expands each breast to a total of 2000cc and wraps an orange collar around her neck.

After more brain scans, father John announces to her that her brain structure is now predominantly female and showing signs of hypersexuality. Sister Riley didn’t need the brain scans to know that. She has felt like a woman for quite a while now. But she didn’t dare admit it. He probably already knew anyway.

Father John further explains that her body’s natural hormone production corresponds to that of a female as well. As a result, and that they can start reducing some of the drugs that she is given. However, the dosage for arousal will be increased as she has reached level 5.

Her new chamber is larger and even has a window to the outside. While looking at a forest, father John plays Prokofiev’s “Dance of the Knights” showing her new music ***********ion until 1950. He also tells her that she technically has the right to have sex with him and asks whether she wants to claim her right. To both of their surprises, she does request it and she gets fucked deeply in her ass. After downing his load, he announces that as level 5, she has to drink piss from brothers, but explains that they are overhydrated and therefore mostly piss water anyway.

“Let’s start with mine. Come here, sister Riley.”

Sister Riley first frowns but then crawls over to him and opens her mouth. The first few gulps, she clearly struggles, but she dutifully comes back to take her next mouthful. At the end, he shoves his cock down her throat and pisses directly into her stomach. Sister Riley feels conflicted as she was not a big fan of what just happened, but still feels her cock growing. Luckily, father John did not notice as he had already left the chamber.

The next day, she notices the stronger effect of the drugs, as her arousal causes her to stroke her cock, sitting on the bed while she eagerly awaits her first master.

However, father John comes in instead, bringing in a large wolf on a leash. Sister Riley has stopped stroking her still hard cock and looks worried.

“Father John, what is going on? Where is this going?”

“You already know where this is going. The wolf will fuck your ass and you will also suck him off.”

Sister Riley shuffles backwards and gives him a stern look.

“This is crazy, you can’t be serious. He will either bite or fuck me to death. It is huge! Is this thing even a wolf? I don’t think it wants to have sex with a human.”

“That is the least of your concerns. But it is indeed not a normal wolf, but a breed of canine that we have bred for centuries, to be highly aroused, to be attracted to humans, have no refractory period, and to have a massive cock. We feed them well, so they are not hungry and the only thing on their mind is fucking. And you have two holes that are currently not fucked by him.”

“His cock would probably kill me, father John.”

“We already spared you, because you are an external sister. It’s not unusual to have level 4 sister get fucked by them, so your ass is more than ready. Now get on all fours already.”

The wolf is already pulling on the leash, wanting to get close to sister Riley. She carefully goes down on all four, but she stands up immediately when she sees the red cock protruding from the beast’s groin.

“I can’t, I can’t, it’s cock is massive!”

“You had much larger than that. Get down, this is starting to get frustrating.”

Sister Riley sees a stern look in his eyes that she hasn’t seen in a long time. She has to avert her gaze and walks in circles trying to hype herself up.

“Fuck, fuck, fuck. This is so fucked up. How can I even … he says I can so … maybe it is possible? Fuck that’s a big animal! And you say he had sex with a human before, father John?”

He rolls his eyes and exhales dismissively.

“Yes, countless times and no one died.”

She stops in front of the beast and takes a deep breath. Eventually, she turns away, closes her eyes, and obediently goes down on all four. As soon as she is in position, father John lets go of the leash and the wolf pounces on his new fuck hole. The wolf pokes around, trying to find her ass, so she has to grab the hard member and guide it towards her ass. He has no mercy and pierces through her sphincter without any disregard for his new fuck toy. Once he is fully inside, he starts thrusting, while sister Riley groans, trying to adjust to the wolf poking in her ass.

After a few minutes, he shoots his load into her ass and pulls his cock out. The wolf is a lot calmer now, but still fully erect. Father John reminds her.

“That was your first hole, now time for the other one.”

Sister Riley sighs and reluctantly reaches for the foreign object that had just ravaged her ass, examining it thoroughly, trying to befriend a thing she does not want to put in her mouth. However, feeling that father John is becoming impatient, she just closes her eyes and puts it in her mouth. While she blows the wolf, father John keeps explaining.

“Do you see the big red knot at the base? If you get that in your ass as well, he can’t thrust as much. But it will also mean that you have to take 30 cm (11.8 inches) of stiff cock in your ass. And we both know you can. So, once you swallowed his load, you will take him in your ass one more time, including the knot.”

She had not even thought about swallowing and is now confronted with even bigger challenges. With faint sobbing, she continues pleasing the wolf, until he shoots his second load in her mouth. Her cheeks are gradually puffing up, trying to hold everything that is pumped in her mouth. She gives a surprised look at father John, who is laughing a little bit.

“Yeah, that is about 50ml (1.7 ounces) of wolf cum. A bit more than a shot glass. We have bred them well.”

Sister Riley is kneeling on the ground, needing several gulps until her mouth is finally empty. She catches her breath for a bit, but does not dare to look up, knowing that there is still one more task at hand. After a short while, she goes down to all four, hoping that the wolf would not be interested anymore. The beast shatters her hope and mounts her ass another time. However, when he starts to thrust, sister Riley reaches back and grabs his knot, pulling him closer to her.

She is struggling, feeling the tip of his cock digging deep inside her guts while her sphincter is stretching in order to accommodate the huge knot. After some fighting with the animal, she manages to get all of it inside, but the relief of her sphincter closing is overshadowed by the penis driving deep inside her ass. Being pushed so close to her limit, she groans loudly. But father John does not pay much attention to her struggles and hands her a toy.

She gives him a defeated look, but cannot deny her raging erection, hoping that the only reason is the drugs and not the cock in her ass. Sister Riley puts her dick in the toy, which starts stroking and vibrating her rock-hard member. At first, she tries not to moan, ashamed of being aroused while a wolf is in her ass, but the toy feels too good, after not having come for at least two hours. Once the wolf shots another load in her ass, she can’t contain herself anymore and comes as well.

The wolf pulls out and she removes her throbbing member out of the toy as well. Afterwards, father John leads the wolf to a bed in the corner.

“The animal will stay with you for a while. This allows you to train with a specimen that you are familiar with and you will have less problems getting fucked by other wolves. You are his bitch now. Congratulations!”

Sister Riley reactively mutters a ‘thanks’ while father John walks over the cupboard to retrieve a butt plug with a fluffy tail.

“From now, you receive masters wearing this butt plug. The plug is as long as the tail, which means everyone can see how deep your ass is already. Furthermore, you walk on all four, when around masters.”

Sister Riley inserts the butt plug in her ass, and hesitantly goes down on all fours, whereupon father John fucks her face one more time. Afterwards, he leaves her alone, so she can get ready for her next master.

In the following days, she gets fucked by her wolf regularly, until it eventually becomes normal for her. However, she trains her ass a lot more, making it easier for her to take him. It takes her 5 months until she meets the requirements for level 6, for which she manages to take a circumference of 34 cm (13.4 inches), a flexible depth of 60 cm (23.6 inches) and a rigid depth of 35 cm (13.8 inches). Father John expands her tits to 2500cc and gives her a metallic bronze colored collar. She actually looked forward to get fucked by him and almost comes while he is drilling in her ass. It scared her at first, when she hears that at level 6, brothers can choke her unconscious, but after a few times, she got used to it, knowing that it turns black faster if she does not fight back too much.

Five months later, the first person she receives is a mistress that had fucked her many times before. Sister Riley already knows that she will have to take a lot up her ass now, but she knows she can handle it and even comes to enjoy it, though she does not know how much of her arousal is caused by her brain and by the drugs. Regardless, sister Riley crawls over with a 62 cm (24.4 inches) tail dangling from her ass, welcoming her with the same submissive enthusiasm as always.

The mistress pulls out the tail plug fast enough to make sure that her slave cries out and subsequently shoves increasingly larger dildos up her ass until she reaches her limit with a barely tapering dildo having a base circumference of 35 cm (13.8) and a top circumference of 20 cm (7.8 inches) and a length of 30 cm (11.8 inches). Sister Riley breathes heavily trying to fight her ass from ejecting the large object.

Then, the mistress pulls out a gun shaped device against one of sister Riley’s tits and shoots. The girl jumps in shock, when she hears some bubbling followed by her breast expanding.

“Mistress, what are you doing?”

“I’m inflating your tits. Your implants are filled with a foaming agent and traces of a liquid that boils at very low temperatures. This gun heats up the liquid, forming bubbles that expand your breasts.”

“What the fuck? I’m scared, mistress, please stop. What if they burst?”

“Shut up and stand still. I want to see how far it goes.”

The mistress keeps shooting in rapid succession, causing sister Riley to panic and back off, waddling backwards with the dildo restricting her movement. The mistress keeps chasing after her shooting relentlessly into the expanding tits until the heating gun stops making sounds. A few silent clicks indicate that the heating gun is empty and the mistress tosses it to the side in frustration.

Sister Riley is scared of both, the angry mistress as well as her expanded breasts. The skin is stretched and her nipples feel tense around the nipple piercings. At first, she barely dares to touch them, but eventually she gropes herself more curiously. Even the mistress starts poking them, but using her hard fingernails.

“They are at 3300cc now. Does it hurt?”

“Yes … especially your fingernail, mistress… are they going to stay like this? I’m freaking out.”

“No, eventually the gas will condense and your tits will shrink to the original size.”

Sister Riley lets out a huge sigh of relief.

“Oh, thank god … I didn’t know that was even possible, mistress.”

“Usually, they do that with sisters already at lower levels. But you are an external sister with normal skin, so we had to wait a bit.”

The mistress disregards the worries of the girl and lays down on the bed, pointing at her crotch. Sister Riley quickly shoves her head between the mistress’s thighs and starts tenderly eating her out. After an hour, she came already 4 times and pissed down her slave’s throat as well.

Afterwards, sister Riley has to put leather cuffs on her ankles and wrists. After binding her arms behind her back, the mistress inflates her tits again to full size and orders her slave to lay on her back. Sister Riley has to pull her legs behind her head, where they are connected with a chain. Once the mistress makes sure that her slave is completely immobile, she pulls out the toy from sister Riley’s ass, who groans loudly during the massive extraction. However, the mistress promptly shuts her up by stuffing her cock in her mouth. Sister Riley obediently sucks herself, while the mistress’s starts shoving her hand into the girl’s ass.

With her feet behind her head, sister Riley’s body is in a folded position that makes it difficult to insert anything in her ass. But the mistress seems to not care and aims to overcome the additional resistance by applying more force. Sister Riley tries to continue sucking her cock, but can’t suppress her occasional groans and screams muffled by her dick. A few times, she wants to pull down her leg, but the chain between her ankles keeps her in her uncomfortable position.

Once most of the mistress’s lower arm is buried deep inside, sister Riley loudly makes clear she has reached her limit.

“That is a good little whore. Look how much your dumb ass can take. Don’t you love having your ass stuffed like that?”

Sister Riley gives her a slow nod with a worried expression.

“Then come in your own mouth. Go ahead my stupid slave. Make yourself come.”

Just like she was told, she starts going faster, trying to move her head as much as her position allows her to. But despite her difficulties to breathe and an arm up her ass, she manages to come a few minutes later. Like a good girl she opens her mouth to show her achievement and then swallows, giving her a nervous smile.

“Don’t smile, keep sucking.”

Sister Riley quickly puts her cock back into her mouth and massages it with her tongue. Her mistress watches her for a while with a sinister smile and then applies more pressure with her arm, causing sister Riley to scream out. The mistress gets closer to the heavily breathing girl and whispers in her ear.

“Shut up, you stupid fuck hole! Do you remember that? Almost a year ago, there was a man who raped me. When he noticed that I come from a wealthy and influential family, he got scared and immediately got into his car, driving through the same night in order to cross the border to Mexico. Even though cameras had identified the car, police said they could not pursue him into a different country. With conventional justice not available, my father turned to the institute, which demanded an enormous amount of money that would be enough to support an entire person’s life. But we gladly paid the price to ruin that man’s life instead. Don’t you think it was worth it, Ethan?”

The mistress pulls her black wig off, revealing her red hair, and watches her slave’s face slowly realizing what is going on. Sister Riley remembers that hair, remembers that woman, and remembers that fateful night. She raped that woman and this is the revenge. She tries to get up, but her shackles keep her immobilized on the bed.

“… Bela? Is that you?”

Bela applies more pressure to sister Riley’s insides.

“Shut up, you stupid fuck hole! That is what you said while you abused me. Now who is the fuck hole, Ethan? I can fit my entire forearm inside your ass already. And you will get fucked every day for the rest of your life. You have been here more than a year already. What have you achieved so far? I asked the institute and you probably already swallowed over 20 liters (5,3 gallons) of cum. That is three times the size of your inflated tits right now. And you probably gulped down 40 liters of piss, which means you consumed more than your own body weight in piss and cum. I, on the other hand, was accepted to one of the most renowned business schools and already passed my first semesters. The second you put your hands on me, you have doomed your own life, whereas I’ll succeed in every endeavor. Oh, what have you done Ethan?”

“I’m sorry, mistress. It was horrible what I did to you. I’m so sorry …”

“I don’t care about your apologies! I don’t want you to feel sorry, to feel redemption or justice! I want you to hate me, hate what happens to you, hate what will happen to you, hate your body, and hate your life. I want you to hate yourself! I want your anger to consume you while being powerless to do anything about it. That is the torment I wish upon you.”

“Ok, I’ll hate myself, mistress!”

Bela stares at her intensively, trying to voice her anger and frustration.

“I want you to hate me.”

“I’ll hate you, mistress!”

She looks perplexed and disappointed at her obedient slave.

“I want you to envy me for my better life.”

“I’ll envy you, mistress.”

Bela hears no fighting spirit in these words. She looks puzzled around the room trying to understand what happened with Ethan. Her angry face gradually shows disappointment and her breathing slows down. After a sigh, she curses a silent ‘fuck’ and withdraws her arm from sister Riley’s ass, who groans from the sudden extraction.

“Are you ok, mistress?”

“This is not how I hoped it would turn out. It seems the institute has gotten to you before me. Your mind looks already broken. I wanted to enjoy the satisfaction of seeing Ethan’s ego shatter, to know his eternal rage. But he is gone. All that is left is this useless docile ‘sister Riley’. I’ve been robbed the best part of my vengeance.”

“I’m sorry, mistress. I’ll try to be angry.”

“Oh, for fuck’s sake, stop it, you are making it only worse. You don’t think like Ethan and don’t look like him either. I wish they didn’t make you that pretty and instead made you as ugly as you are on the inside.”

“You asked them to make me woman, mistress.”

“But they even changed your brain, which means you won’t even suffer from dysmorphia. And these stupid drugs unfortunately make you even enjoy some out of this. What a shame, I hoped my revenge would be sweeter.”

“I’m sorry, mistress.”

Bela rolls her eyes and unleashes the wolf, who promptly jumps on the bed, fucking his bitch’s ass. The animal is well trained and knows to pull out in order to come in her mouth. An hour and six loads later, the time is over and the mistress gets up, while the wolf is still ravaging his human pet.

“Ethan”

“…”

“Sister Riley!”

“Yes, mistress?”

Bela shakes her head in disbelief and throws the key to the shackles onto the bed.

“Happy fucking 20th birthday.”

After she has left the chamber, sister Riley rolls over to the keys and unchains herself. Like on autopilot, she tidies up the room and showers. While she cleans herself, she can reflect on what just happened. All this time she had wondered why she was brought to the institute, but she had already assumed it was some divine justice for assaulting that woman. It turns out that this was indeed the reason, but the justice was not carried out by a higher power, but the very woman she had raped. And the only reason she got caught was because she wanted to violate another woman just days later. It is really her own fault for ending up where she is now.

But the mistress was right. Sister Riley feels closer to her current body than her old one and she enjoys a lot of the action she gets, even the wolf. She has learned long ago that there is no sense in fighting back and that following the rules causes less trouble. Just keep improving and everything will be easier.

Soon after, sister Riley passes the requirements for level 7 by being able to take a circumference of 38 cm (15 inches), a flexible depth of 80 cm (31.5 inches) and a rigid depth of 40 cm (15.7 inches). This time, she comes easily when father John is fucking her ass. Afterwards, she gets a silver collar and is led to surgery in order to insert new 3000cc implants that can be filled even more.

It takes her another eight months to reach level 8. Her ass can now take a circumference of 42 cm (16.5 inches), a flexible depth of 80 cm (31.5 inches) and a rigid depth of 44 cm (17.3 inches). She feels pride when she is given her gold collar and passionately pleases father John’s cock with both of her holes.

For her new chamber, they take the elevator down, where finds a luxuriously decorated room with paintings. However, it does not take her long to notice a second door, leading them outside. For a moment, she enjoys the fresh air, thinking that she gets her own little garden to relax. But her smile fades when father John whistles for a large horse. She has been here long enough to know what he wants from her and tries to run back through the door, but father John grabs her by the arm.

“The stallion will fuck your ass today, but you decide whether you will be conscious while he does.”

“Are you crazy? I’ve read the stories on the internet. People die from getting impaled by horse cock. You can’t expect me to do this … father John.”

“We would not be standing here if you weren’t ready. This is even an easier one, with a length of only 40 cm (15.7 inches). Pureblood Sisters usually have to go right for 45 cm (17.7 inches). If you stop whining, I’ll even let you use lube.”

“That is the choice I get? It’s a fucking horse, it’s too different from a human! I can’t just go on all four like I did with the wolf, father John.”

Father John presses a button and a support frame extends from the wall. The horse seems to know what it means and runs to the little girl standing next to the support frame.

“If you let him fuck you right now, you can use lube. If we argue for 5 more minutes, lube is off the table. If there is no horse cock in your ass in 10 minutes, I will tie you to the frame and then it may actually be dangerous for you. You decide.”

Sister Riley exhales with anger and shakes her head. Her mind is wrestling with itself and the hopeless situation. Eventually, she leans against the wall, starting to sob. A hint of a smile appears of father John, who understands that these are not pleading cries, but cries of accepting her fate. With closed eyes and clenched fists, she takes a big breath and pauses for a moment.

“I’d like the lube please, father John.”

She inserts the bottle in her ass and squirts a large amount directly into her guts. Then she pours more into her hands and carefully approaches the large beast, which seems to be eager to get some action, as his cock is already growing.

Sister Riley thoroughly lubes up the long shaft, which finally stops growing when it has reached its full size. The randy stallion follows her eagerly to the support frame and lifts his front hooves over an upper bar. Sister Riley steps under him and reluctantly guides the big cock to her ass, where the horse immediately starts pushing until he manages to pop inside the scared little girl. She pushes her pelvis as far forward as possible, trying to minimize the depth of the stallion’s thrusts to about 25 cm (9.6 inches). After a while, sister Riley manages to find a good angle, in which the horse can thrust freely, allowing her to calm down from her initial panic.

However, father John urges her to go deeper. Despite all her instincts telling her to move forward, she slowly backs into the horse, while carefully adjusting the angle of her body, in order to avoid being harmed by the massive member. The deeper it goes, the slower she moves, feeling more and more of the horse cock poking inside her guts. After a long time, she can feel her body reaching its limit at 30 cm (11.8 inches). But father John instructs her to keep pushing until 33 cm (13 inches) at which point she is finally allowed to stay still. For a moment, listens to her body, checking if there is any unusual harm, apart from the horse cock in her ass.

She is still alive! Father John seems less enthusiastic about her achievement and is rather interesting in boasting about the horse breed.

“Normally, horses do not thrust a lot, maybe ten times before they come. So, we bred them to last a lot longer. You would be surprised about the difference in muscle structures that allow them to thrust so much.”

Sister Riley tries to look interested, but can only focus on the massive member ravaging her ass. Suddenly, the horse flares its nostrils and breathes heavier, while speeding up its thrusting until it pushes its cock as deep as possible into the little human’s ass. Sister Riley can feel a seemingly endless amount of jizz filling up her insides. In the meantime, father John has already fetched a bucket and places it in front of her. Just when the horse is about to start thrusting again, she finally pulls herself forward and extracts the biggest cock she ever had from her ass. Without needing to be told what to do, she dutifully empties her insides into the bucket. She shakes her head in disbelief when she sees how much the horse had pumped into her.

“About half a liter (8.5 ounces) and they also can go many times in a row.”

Sister Riley is a bit disappointed that he seems prouder about the horse breed than her miraculous achievement just now. But she disregards her thoughts, lifts the bucket to her lips, and downs everything in one go. For a moment, she can catch her breath, but she already noticed that he is still standing there, not intending to go inside already. This time, she takes the initiative, avoiding any discussion and starts jerking off the still hard horse.

She can get the head of the horse inside her mouth, but there is no chance that she can get any of that into her throat. Unfortunately, that means that the stallion keeps thrusting against the back of her throat. However, she can eventually contain his movements, by stroking his shaft fast enough and with enough pressure. When he still starts to thrust, she knows she has to buckle up, close her lips around the head and start drinking as fast as possible. When the horse starts coming, her cheeks inflate and the pressure almost pops the cock out of her mouth. But she gulps everything down quickly and eventually, the stream of cum slows down.

After a few steps backwards, away from the animal’s hooves, she sits on the ground, breathing heavily and holding her stomach.

“There you go, I made the horse come twice without dying a single time. Are you happy, father John?”

“You did well, in case you needed to hear that. But you know this was not the last time. Your chamber is right next to the horse, because it will now replace the wolf.”

“The masters made me fuck the wolf pretty much every day, father John.”

“And now will the stallion. You really need everything spelled out for you, do you?”

“I keep stretching my ass, but you just come with a larger animal! What’s next, a whale?”

“No, horses are the largest animal we have. They could be bred to have cocks so large, no one can take it all anyway, so why bother with a different animal?”

“I’m already at the highest level, right? I have a gold collar, that should be the limit I presume … doesn’t that make sense, father John?”

“It goes up to level 10, next would be an emerald collar followed by a diamond collar.”

He notices her utter resignation hearing the unexpected news.

“But those are goals for the pureblood sisters from the institute. For an external sister, you got pretty far. As a matter of fact, as a level 8, you are allowed to request a sister for one hour per week. You can be a mistress over her.”

These words of consolation are even less encouraging, as it sounds like she has no chance of reaching level 9. But she loses these thoughts when she hears about requesting her own temporary slave, a service that she subsequently uses repeatedly as soon as her last slave leaves her chamber.

Four months later, Bela visits her again for the 21st birthday, where she gets to brag about finishing her bachelor degree and sister Riley has to show how she can get fucked by her stallion for half an hour. A year later, Bela boasts about her millionaire boyfriend while sister Riley’s achievement is to get fucked by her horse for an entire hour.

Despite her life going nowhere, she keeps practicing and actually manages to reach level 9 eventually, being able to take up her ass a circumference of 46 cm (18.1 inches), a flexible depth of 90 cm (35.4 inches), and a rigid depth of 47 cm (18.5 inches). As a result, her implants are expanded to 4000cc and she gets to wear an emerald collar and receives pills with a stronger dosage. Father John explains to her that she now gets to request either a brother or a sister once per week.

Half a year later, she is again visited by father John with an unexpected offer.

“You have made quite the progress, but unfortunately, I can’t offer you all the perks that come with it. Usually, level 9 sisters occasionally travel to institutes in other countries, but external sisters like you do not travel, as their obedience is not certain.”

“Fucking hell, after all these years of doing everything that I was asked to, you still don’t trust me, father John? Even after reaching level 9?”

“I will always be careful with externals. Because the institute is cautious, the masters are able to trust you. But I admit, I did not expect you to reach level 9, albeit that was probably only possible because we had stretched your pelvic bones to have a larger opening when we modified your body. But it would seem that you have reached your limit. I don’t think you will ever get to level 10…”

Sister Riley looks down in disappointment. She agrees with him, but didn’t want to hear it said out loud.

“…however, there is something special about external sisters that pureblood sisters do not have. You have been outside; you know the world.”

“… which has helped me zero times, father John. On the contrary, I am aware of what I am missing and can even be mocked about it. Bela visits me on my birthdays to brag about her great life.”

Father John can’t help but smirk at her comment.

“Yes, our client has paid a lot to have you brought to the institute. And we have just received an order, about bringing in a new target to become a potential sister. We need a sister who can navigate the outside world to play the bait, to seduce our target. I offer you the chance to do that. As a reward, we will give you a level 10 chamber. What do you say?”

Sister Riley is surprised by the offer. She has not seen the outside world in years. She tries to remember. The last time was when she met sister Casey. Wait, was that why …

“Was that the same deal for sister Casey?”

“Yes, abducting you bumped her up. However, she was stuck at level 8 and we pushed her to level 9.”

Sister Riley takes a long time to think, but eventually shakes her head much to the surprise of father John.

“Thank you for the offer, father John, but I refuse.”

“Huh, I did not expect that answer. Why?”

“I don’t want to be responsible for that person to be enslaved. I admit that being constantly horny and having non-stop sex is enjoyable, but I don’t think it is worth my freedom. Maybe I deserve this for my actions in the past, but I don’t want to force that onto another person.”

Father John has an almost disgusted expression on his face, which she probably had never seen before, despite what she has seen in the institute.

“You reject the offer out of compassion for some random person? Your naivety and logic are astonishing. I guess you still have to learn a lot here in the institute. But fine by me, I’ll respect your decision, however, not your reasoning.”

After she rejected the offer, she continued with her daily routine. However, a month later, she is booked together with another sister. Sister Riley has to go to chamber of the other sister, which can only mean that it is a level 10 room. When she goes through the door, she looks in awe at the beautiful multi-room apartment, until she sees a familiar women on the bed.

“Sister Casey? This is your room?”

“Hi, sister Riley, come sit with me!”

On the way to the bed, it slowly dawns on her.

“Sister Casey, how did you get this room? I’m worried that you made a deal with father John.”

“Yes, I did. I was surprised to hear that you rejected his offer.”

“I … I didn’t want the institute to make another slave.”

“Oh honey, it was not about an ‘if’ but a ‘by whom’. There are many other sisters who would have done it anyway. You can’t prevent an order from being fulfilled. Do you really think the institute would decline the order of a client because one of us would not play along?”

“I don’t know. It didn’t feel right. I mean, you did the same to me. Do you not feel bad about it?”

“I do … honestly. But you have to play the hand that you are dealt. At some point, there is no perfect solution and you need to compromise between you and your ideals.”

Sister Riley drops onto the bed with a face of defeat.

“So, I made the wrong decision. I have gained nothing.”

“Well, you have gained my admiration, I can tell you that. But other than that … not really anything, no. I guess you now know that you take the offer if he gives you one more chance.”

Their conversation is interrupted by their master walking inside, pulling behind a trolley with various devices. The two sisters quickly scurry over to serve him.

After sister Riley sucked him hard, sister Casey takes him in her ass and rides him gently and passionately, while she is getting sucked of by sister Riley.

Once they made the master come, the girls lie on the bed in order to please each other. After sucking each other’s dicks for a while, they play with each other’s asses until they both have an arm inserted deep inside their rectums. However, this does not prevent the experienced girls from pleasing each other until they swallowed the other’s load.

The master takes something of his trolley and hands it to sister Riley, who takes it with her still free hand.

“I had this award made for sister Casey. Can you read to her what it says?”

“It says … ‘winner of the most cold-hearted bitch of the year’, master.”

“Can you guess why she gets the award?”

“Is it … because she helped abduct another slave, master?”

“Good job, you are correct. And when you say another slave, who are you talking about?”

“… about me, master. She seduced and drugged me. Now I am here …”

“Exactly. You probably noticed that the award is shaped like a huge penis. Please hand her the award.”

Sister Riley withdraws her hand from sister Casey’s ass, and inserts the golden cock instead. Despite having been stretching by a thorough fisting, it takes some time until her ass swallows it up entirely.

The master then gets another trophy and hands it to sister Casey. She takes it and reads it out loud.

“This one says ‘winner of the most naive sucker of the year’. My guess is that because she thought rejecting the offer would prevent the abduction.”

“But the target was still taken in. How come?”

“I took the offer. Just like with sister Riley before, I sedated the target and now he is in a half year coma, being transformed to a woman.”

“That was indeed quite cold-hearted. Well, go ahead, give her the award.”

She proceeds to replace her arm with a large golden dildo pushed deep inside sister Riley’s guts. Afterwards, sister Casey gets up to thank her master by sucking him off, while sister Riley carefully removes the award from sister Casey’s ass.

Once she gulped down his load, the master plays loudly plays ‘we are the Champions’, while sister Casey rides sister Riley’s cock, who still has her big award in her ass. He makes them kiss each other tenderly and embrace for a slow fuck between sister Riley and her abductor.

Once the session is over, both girls are told that they get to keep their awards forever to help them remember what happened. Sister Riley has to walk back to her chamber with her ass still carrying the large and heavy gold trophy. Once she is back, she puts it in her bathroom, looking at her eternal reminder for when she thought she could save another person from the institute.

On the next two birthdays of sister Riley, Bela comes again to brag about her engagement with her millionaire boyfriend and that she has gotten her degree from the university. Sister Riley has lost her sense of time and is surprised to hear that she had been fucked for five years already. Her life had become stagnant with no future. Even in the institute she does not manage to achieve any new milestones, staying firmly at level 9. The only noticeable improvement is that she got a stallion with a 45 cm (17.7 inches) cock that she barely manages to take in her ass. A fact that Bela enjoys when she makes sister Riley take the horse for an hour.

When father John approaches her a few months later with another offer to help with an abduction she almost surprises herself by how quickly she agrees. His victorious smirk does not matter. She won’t pass the reward to some other girl this time.

To her surprise, she is given some clothes that she gets to wear, while father John explains the plan. It now occurs to her that this is the first time in her life that she wears women’s clothes.

“In one hour, you will drive with two men to Chicago. Your target is this man Bryce Geller. He is dating the daughter of one of our clients, who hates him and is quite certain he is a cheater, but the daughter is too infatuated to listen to her father. He asked us to solve his problem. You will flirt with him, go back to his place, and inject this syringe into him.”

“What is it, father?”

“Etorphine. It instantly immobilizes him. Then you inform the men in the car with this phone. You can’t contact anyone else with this, so don’t even bother trying.”

She has to sit down for a moment in order to process everything. Not only does the plan scares her, she also feels like she is reliving trauma, seeing the other side of her abduction. Father John does not show much sympathy for her anxiety.

“What, are you not up to the task?”

No, she won’t back out anymore. She rather faces the danger of this unknown man than more years of regret. After taking a big breath, she gets up and picks up the luggage they brought her.

“You should rather worry about setting up your medical equipment, because I’ll soon bring you your next sister, father John.”

He smirks and accompanies her to the car. She was hoping to finally see the outside, but unfortunately has to spend the entire ride in the back of a van, where she at least gets to study all the information she is provided. In the van she puts on a bright red wig and heavy make-up, changing her appearance so far that, for the second time, she can’t recognize herself in the mirror. When they reach their location, sister Riley changes into skimpier clothing and the trio waits until they see their target entering a bar.

The moment she steps out of the car, countless memories of her previous life in civilization come back to her. The thought of escaping crosses her mind, but when she glances back in the van, she can see one of the men showing her a device that tracks her location. After a few steps in the high heels, she realizes that she would not be able to run away anyway.

Inside the bar, men and women immediately notice her, but she ignores all the onlookers, and steers towards a seat at the bar close to her target. Prior to her journey, father John had drained her breasts in order to reduce the size down to 2000cc, which felt tiny to her, but still enormous to the people in the bar. Everyone notices her, including the cheating son of a bitch, Bryce. After some eye contact and exchanges of smiles, she sits down at his table, flirting with her target.

Now that she interacts with normal people in the outside world, she notices how easy it is to twist men around her finger. As much as she enjoys her temporary power, she gradually realizes that this seemingly real interaction is just as fake as any previous one in the institute, and she focuses back on her mission.

Copying the playbook of sister Casey, she pretends to be drunk and flirtatious, which easily nets her a ride back to his place. However, she is wary about the light coming out of the windows and when they enter, they are greeted by four of his friends. Fuck, she can’t sedate them all! And even if she gets some alone time with Bryce, she can’t get his unconscious body out of the apartment while they are here.

After some chatter, she learns that the friends wanted to hang out with him, but will leave early in the morning. Bryce seems stoked about the idea and calls sister Riley a taxi, so she can get safely home. Shit! Just a second ago, he was about to cheat on his girlfriend, but at the worst time he acts like a gentleman. Quick, you need a plan!

“Wait Bryce, cancel the taxi, can I stay?”

“Why?”

She turns to the entire group of men.

“Look, this is my last day in Chicago, and I had this fantasy for the longest time …”

The room suddenly gets silent and everyone looks at the hot girl playing with her hair.

“I always had this fantasy of getting fucked a group of man … thoroughly. Would you guys do me the favor?”

The men seem unsure, whether she actually meant it and hesitate for a moment. However, when she slowly pulls down her top, revealing her gigantic tits, the room is cheering. Sister Riley eagerly continues pulling down her dress, until she remembers that they do not know she has a cock. The men see that she is suddenly a lot more nervous when she continues to pull down the entire dress, revealing the longest cock in the room dangling between her legs.

The men go silent and look at each other while sister Riley’s face grows red. However, as one of the men starts to shrug, so do the others, and the cheering resumes.

With her confidence returning, Sister Riley walks to Bryce, unzips his pants, and starts blowing him. After a few minutes, she is surprised to see that none of the men starts approaching her, but then she remembers that outside of the institute, men show restraint. So, she encourages them a bit.

“Guys, fucking my ass feels amazing. Please gentlemen, ravage me. Nothing is off limits.”

Shortly after, the first one starts drilling her ass, while she jerks off another one. When Bryce is about to come and wants to pull out, she pushes him into her throat and looks him deeply into the eyes while swallowing his load. After giving his penis a loving goodbye kiss, she turns around, and sucks off the guy that had just fucked her ass.

Compared to what she does at the institute, the five men pose no challenge for her, but for them it is the greatest night ever.

An hour later, she has downed everyone’s load and they are happy sitting around drinking beer, while sister Riley excuses herself to go to the bathroom. Inside, she messages the men in the van that she will try to stay in the apartment until the friends of Bryce leave again. Once she knows that they are informed, she heads back into the main room, still naked, while the men are already dressed again.

They start thanking her for the nice evening, which means they probably want to kick her out already. For fuck’s sake, why do they not continue ravaging her?

She tries to steer the conversation back to sex. When she is out of ideas, she sits down and starts stroking herself until her cock has grown rock hard with a length of 25 cm (9.8 inches). The men sit back down, mesmerized by the show she is putting up. One of them eventually is brave enough to ask if he can jerk her a dick for a bit. Seeing her moan from all the pleasure, everyone wants to have a go. After half an hour of edging, she pops the leaking cock in her mouth and sucks herself. The captivated crowd watches the rare spectacle and cheers loudly when she finally comes, shooting ropes of cum into her mouth.

After catching her breath, she crawls to one of the men and pulls out his cock. It is hard again. While she sucks on his shaft, she wiggles her ass, inviting the rest of them. Sure enough, moments later the gets thoroughly fucked in the ass again.

One and half hours later, all the men are satisfied, sitting exhausted in the room. Sister Riley manages to squeeze another half an hour of conversation out of them until they start again to hint at calling her a taxi. It is time for the next show, but the guys can’t go another round. That is ok, they don’t need their dicks to have fun.

“Have the gentlemen here ever fisted an ass?”

Everyone turns to her with a curious look. As they all stand there frozen, not knowing what to say, sister Riley turns around and bends over. Bryce drops his phone and walks up to her, pressing his index finger into her ass. Encouraged by her moans, he proceeds to enter more and more fingers, until he presses his knuckles past her sphincter. The room goals wild and everyone asks him to go deeper. Without much problems, the rest of his hand and subsequently his wrist vanish inside her ass. She stops him for a moment, so she can crawl to a sofa in order to brace herself. After she nods at him, he keeps pushing, until half of his forearm is in her ass.

Now everyone wants to take a turn fisting the beauty. They get quite overzealous, but sister Riley does not stop them, hoping that they get hard for another round. After getting fisted for half an hour, she tries to change the object as she feels a bit sore. When she looks around, she sees an empty beer bottle and proceeds to insert it, bottom first, into her ass. With only a small tip poking out, she gets up and poses in front of the crowd.

However, the men soon demand more and bring her a 750 ml (25 ounces) wine bottle. She nods and even lets one of them insert the large glass bottle. It takes her some time until she manages to get the bottom inside and once she has 20 cm of it inside, she stops the man. She needs a short break and lays face down on the sofa, as she cannot sit down with the bottle sticking out of her ass.

While she is catching her breath, one of the guys comes back from the kitchen with a 1.5 liter (50 ounces) soda bottle, giving his fellas an excited look. However, one of the more sober men calms him down.

“I think we have pushed her far enough tonight. I don’t think she can go larger anyway.”

“I know, I know, I was just kidding. I know it is too big. I’d let her fuck me if she got that thing inside.”

The men are laughing, but sister Riley gives them an inquisitive look.

“I don’t know if I can fit it up my ass, but I am curious about it. I want to take you up on the bet. If I get it inside, I get to fuck your ass, gently of course.”

The guy stops smiling and gets a worried look. But the other guys keep encouraging him to take the bet until he relents.

“Alright, you have done a lot for us, I should let you have some fun as well. I mean, who else should take my ass other than the fucking hottest piece of ass I have ever seen. But only if you get it in. And, you have to have keep it inside of you while you … well, while you take me for a ride I guess.”

Sister Riley wobbles over, still with the wine bottle inside of her, and shakes his hand. The guy even gets to push the bottom of the bottle inside her ass. However, afterwards, she needs to sit on it, using her entire body weight in order to force it slowly inside. Luckily for her, the bottle has a smooth surface with a cylindrical shape. Therefore, she gets the first half of the bottle inside quite easily. However, her ass is starting to struggle with the depth. Her progress slows down, but she keeps slamming her ass on the bottle until her sphincter closes around the top, with only the bottle neck sticking out. While getting applause from everyone, she lays face down on the sofa again.

“Thanks guys, but I can barely move. The bottle is stretching my insides so much. I don’t need to fuck that guy’s ass.”

However, the men don’t want to hear anything like that and turn her on her back, revealing her limp dick. Against her objections, they start playing with her tits and masturbating her cock and until it magically hardens to its full size again. One of the men gets a bottle of lube and applies it thoroughly on her cock. Sister Riley gets a bit angry when she sees that.

“You sons of bitches had lube? Why didn’t you tell me earlier? That would have made the bottle a lot easier!”

But having her giant cock stroked feels too good to hang on to her anger and soon they get her to moan, despite the large bottle stuck in her ass. Eventually, the guy who lost the bet lowers his ass onto her lubes up tool. He manages to get 15 cm (5.9 inches) inside, but then has to get up.

“Fuck, no way, she is too large, I can’t sit on it fellas. But I think I honored my part of the deal, don’t you think?”

Sister Riley shoves him to the side and very carefully gets up from the sofa, while cursing them out.

“Goddamit, I gotta do everything myself huh? Come on man, get on all four and let me take your ass, I promise I’ll be gentle.”

He reluctantly agrees while the others are cheering at the beautiful girl, groaning with the bottle in her ass, while she kneels behind the man. Just like she promised, she gently inserts her cock in her ass and stops going further when it gets uncomfortable for him. After some shallow thrusts, she gets into a steady rhythm, causing the man to quietly moan in pleasure while the girl groans in discomfort. Eventually, she reaches around and starts massaging his cock with her hand.

Initially, the men around were laughing at their friend getting fucked in the ass, but when they see her pleasing him, they gradually start cheering. Against all odds, she manages to make him come, but not without catching his cum with her hand in order to gulp it down. The room erupts in cheers, while she stays kneeling on the ground, stiff as a board, trying to move as little as possible.

One of the men reaches for her cock and starts stroking it again.

“I wonder if you can come with that thing stuck in your ass.”

She looks over to him and shakes her head in a pleading manner.

“Please don’t… my horniness is the only thing that allows me to endure the bottle.”

The men don’t care, and pick her up, laying her upper back on the ground, with her ass leaning against the sofa so that her legs go over her head and her cock is pointing right at her mouth. While four men are holding her down, Bryce is jerking her large cock, regardless of her pleads for them to stop. Everyone gets excited when her legs start to shake until she buckles up, as she can’t fight against her orgasm

“Fuuuuuuuuuuuuuuuuuck! Fuuuu …”

Her screams are muffled by a large ropes of cum shooting straight into her mouth. She didn’t come for many hours, while being horny herself, which has built up to a powerful climax.

Once she has calmed down, they let go of her and she rolls to the side, holding her ass. She wants to pull it out, but the guys stop her.

“Wait, wait, you got me hard again. Please, suck me off. I know that was mean, but I’m rock hard. Make me come one more time and you can take it out.”

Sister Riley shakes her head in frustration, but eventually relents as she got what she wanted. She got another session out of them. It’s already 5 o’clock in the morning. She almost made it.

Despite being held down against her will just minutes before, she gently sucks them all off, catching every last drop of cum. Once everyone is satisfied, they thank her and leave the apartment. Bryce sees them off at the door and the second the door closes, he feels a stinging pain in his neck. He turns around with a shock in his eyes and sees sister Riley with a syringe in her hand.

With a sigh of relief, she calls the men from the car, who show up moments later to help her get the bottle out of her ass. Afterwards, they pack up Bryce and head back to the institute, where father John is displeased to hear that she had sex with him, as he had to change the *********** for when he wakes up in half a year. But he nonetheless commends her for adapting to the new situation at the apartment.

The next day, she is brought to her new level 10 chamber, with multiple rooms and luxurious decoration. However, she is surprised to find a computer setup opposite her bed. Father John explains to her that she will now do video stream from 5 to 6 o’clock in the evening. But if she does not manage to get a sufficiently large audience, her streaming time will be reduced or entirely eliminated. In return, she gets some very limited access to the internet, which allows her to watch movies or news during her training. However, father John repeatedly warns her that the stream and her internet traffic is monitored strictly and that she will have to answer to any conspicuousness. After having fought so long for her new privileges, she does not plan to risk them anyway.

Initially, she masturbates in her streams, assuming that her viewers would want to see her pleasuring herself. However, she quickly notices that her views plummet unless she jams large toys up her ass. Any larger toy quickly becomes a new normal and she has to repeatedly increase the size, until she only uses exclusively the largest toy that she can fit inside.

Once the size cannot be increased, the viewers demand her to increase the time that the toy is inside her. A few seconds turn to a minute, to five minutes, to half an hour, to the entire session. In the end, she has to have the toy already buried in her ass when the stream starts. Because it still slips out from time to time, the viewers demand that the toy is held in place by leather straps around her pelvis. The straps are connected by locks, which are opened afterwards by one of the managing sisters. As a result, sister Riley has to wait after each streaming session for someone to remove the straps and the toy.

However, especially new viewers now complain about not being able to see the size of the toy anymore. The dildo subsequently is modified to be hollow with an opening at the bottom that allows looking inside. The hollow construction results in a new game, where sister Riley inserts water into the hollow toy and subsequently closes the toy with a screw cap. The viewer numbers increased a lot, as everyone wants to see how much water she can fit into the toy and how she struggles to move with the weight from liters of water in her ass.

Eventually, she performs her shows in a water pool on a different level of the institute, where she can easily fill the dildo with water to be carried around or fill the toy with air, pushing her up, when she swims in the pool.

Despite performing the show for years, she struggles every time with the toy in her ass displacing all her organs and stretching out her ass. A few times, the size of the toy is even further increased, which means she never really gets used to it.

However, her struggles are not in vain. The institute removes some limitations to her internet access and increased her pill dosage. But most of all, she loves the adoration from the audience. During the day, many masters treat her with more respect and in the evening, during her show, she feels like a diva adored by the masses. She used to envy online influencers with a large following and now she gets to experience it herself. Her fame and popularity feels intoxicating, pushing her to continue using the large toy in her shows, despite the strain in puts on her body. Despite all odds, she manages to feel a purpose in life.

After one of the shows, she accidentally drops her towel in the pool. When she looks around for a tool to fish it out, she notices that a door in the back of the room is not unlocked. As she glances inside, she sees a small janitor room with various tools. But since she can’t see a long rod, she closes the door again. However, she pauses with her hand still on the door knob. This is the first time that she saw a room that she was not supposed to be in. Usually, everything is strictly locked up, but someone must have forgotten about this door. Her curiosity gets the better of her and she goes back in, looking around. She finds nothing too fancy, just some tools required for pool maintenance. It still feels like she is given a glimpse behind the curtain.

When she looks out of a window of the room, she can see the park and the forest behind it. Usually, it is sprawling with masters, sisters, and wolves. But now it is completely empty. Wait, the window has a handle. Can it be opened?

She gasps quietly, when she turns the handle and the window begins to swing open. Sister Riley enjoys some fresh air and chirping in the night. It is a rare occasion for her, since, so far, none of her windows could ever be opened. Probably in order to prevent any escape attempts.

Since this window is located on the sixth floor, no one can jump out of here anyway. What a beautiful night. For a moment, she even forgets the gigantic dildo in her ass. After another minute of enjoying a fleeting sense of freedom, she silently closes the window and hurries back to her room, where the managing sister unlocks the leather straps.

She visits her little window almost every evening from then on. Today was a tough day though. It’s her 27th birthday and Bela bragged about her perfect family with her newborn baby. She kept going on and on about how her lineage will go on and benefit from her successful businesses, whereas sister Riley will die alone, having achieved nothing other than playing cum dumpster for rich people.

It does feel unfair. She works every day, diligently and selflessly and has nothing to show for. Even her beloved audience vanishes the second she switches off the camera. What is really the point? Why continue tomorrow? Her little window may not allow her to escape from the institute, but maybe from life? Her struggles would be over in an instant… but, the thought somehow does not interest her much. She is not going to go out the easy way. Bela gives her grief, but she does not have that much power over her.

Time to go back to the chamber, her ass can’t take the toy much longer.

The next day, sister Riley feels much better, full with energy. She skips lunch and instead stretches her ass a bit more, while listening to the second movement of Vivaldi’s summer. While she has access to all music, she has gained some appreciation for classical music. The piece ends, and she receives her first master of the afternoon.

After her last master of the day, she puts the gigantic dildo in her ass and waits for the managing sister to strap it in place. Time for the third movement of the summer. While the managing sister locks the strap in place, sister Riley looks outside the window, watching dark clouds blacking out the sun. On the way to the pool, the rumbling of a storm can be heard and lighting occasionally brightens up the dark windows.

When she is standing alone at the pool with her heart pounding, in her head, she still listening to Vivaldi’s storm. After taking a deep breath, she walks past her streaming setup and goes for the door to her window of freedom. She opens it and looks down. The park is completely empty and entirely dark due to the storm.

Sister Riley reaches for her dildo and screws off the cap, causing a long bundle of rope and two shower sandals to fall out. The rope had been used by the masters countless times to bind her, but today it might set her free. She attaches one of the ends to the door handle and throws the other end down the window. It reaches all the way down, just as she had hoped. More rope would not have fit into her ass.

Just like the weather forecast on the internet had predicted, the institute is getting hit by a massive storm today and heavy rain has started to pour.

Her fear of heights screams at her to stay inside, but Sister Riley overpowers her instincts and climbs out of the window. As fast as she can, she climbs down until her feet feel wet grass. She made it! Now put on the sandals and start running into the forest! Aaaaah fuck, the dildo is too big. All that stretching did not prepare her for the escape. Ok, don’t run, but keep moving, goddammit!

The admin of the institute sits on his chair, playing a video game, when he hears a lot of messages appearing on his computer.

“Huh? What’s with all these messages? Let’s see:‘Where is the stream?’, ‘When does the stream start?’ ‘The steam is not starting!’ … What stream are they talking about? It seems to be … sister Riley … hang on, is that not the pool whore? Lemme check … yeah, it hasn’t started. Fuck, I can’t pause online games…”

He calls one of the managing sisters, who checks in the pool and sees that sister Riley is not there. After looking inside the water that she didn’t drown, she searches around and notices rain noise from the storage room. The door can’t be opened as sister Riley had tied the rope around a bush on the ground, which holds the door shut. Only after one of the guards kicks it open do they realize that the girl had roped down. When father John answers the phone, he only hears a guard screaming.

“Sister Riley has escaped! She is gone from the pool room!”

“Dispatch the tracking team and sound the alarms. I’ll come down to the control room!”

Sister Riley is already in the forest, when she hears a faint alarm behind her, but she is too far to see the searchlights scanning the park.

The rain feels cold on her skin, which she welcomes having ran so fast. But the dildo in her ass makes it difficult to move. She tries to walk as upright as possible, almost as if she had, well … a stick up her ass. But she keeps pressing forward. She needs to get going, because she can’t turn around anymore.

After half an hour, she also hears barking, which was terrible news for her. She had hoped that the rain would wash away her scent, but the dogs might still catch small traces of her. Another problem is her raging boner, which made it awkward to run. She received level 10 drugs, which are incredibly potent, even in a state of fear.

Since she needs a bit of rest anyway, she soon proceeds to quickly jerk off. Instinctively, she is about to catch it with her mouth, but instead she shoots into the bushes, creating a possible source of scent, distracting the hounds. However, coming made her sphincter clinch hard onto the toy, causing her ass to hurt even more. After a few seconds of cursing out the pain, she proceeds, but not before backtracking a few steps from where she jizzed into the bush and continuing at a different angle.

At first, the barking vanishes completely. However, half an hour later, they seem to get closer again. Despite dreading the pain in her ass, she decides to again jizz into the bushes and to proceed at an angle from her original direction, which seems to work, as she manages to shake off her pursuer. An hour later, she has to pull off the trick one more time, until she finally hears no one chasing her anymore.

Completely exhausted, she lies down on a dry spot under a rock in order to catch her breath. Her ass hurts and the rain feels so cold to her naked body. However, just a few minutes later, the exhausted girl falls asleep.

Sister Riley is woken up by bird’s chirping in the early morning. For a moment, she forgets where she is, but the dildo in her ass quickly reminds her of her getaway. She feels so hungry, because she didn’t eat anything for the last two days, so her guts stay empty for the toy.

Even though her entire body hurts, she forces herself to continue walking. After half an hour of walking in the hot sun, she notices that her breasts feel tense and realizes that the heat caused her implants to expand. But with nothing to cool her down, she has to endure her stretched tits now as well.

After a while, she finally comes across a street. Civilization! If she just walks long enough on it, some car will have to eventually show up.

Not long after, she hears a truck approaching. She immediately starts waving her hands and jumping, bouncing her giant tits. However, the truck just honks its horn and drives past her. Two more trucks ignore her until a small car comes along.

An old lady looks confused at the naked girl.

“What is this? What are you doing, young lady?”

“Thank God you stopped. Please, you gotta help me. I escaped a prison and they are after me. Please take me with you!”

However, when sister Riley tries to open the door, she finds it locked. As she knocks against the window, the old woman shakes her head with a dismissive face.

“I’m not going to fall for these tricks. I’ve seen it on TV. You pretend that you are in danger and once I let you in, you will rob me. Shame on you and shame on you running around naked.”

“No, I swear to God, I’m not trying to trick you. Please help me. I … I’ll get in your trunk if you want. Anything, just please take me with you …”

The old lady only gives her a mean look and steps on the gas. Sister Riley screams out of desperation.

“Pleeeeeeeeeeeeease, help meee! You are my only hooooooope! Aaaaaaaaah!”

Suddenly, the car slows down and breaks at the side of the road. Without disregard for the toy in her ass and the bouncing tits, sister Riley runs as fast as possible to the waiting car. When she reaches the window, she uses her little remaining breath to thank her.

“Thank … you … so … much …”

“If you try anything funny, I swear to god, you will regret it… now, get in.”

Sister Riley jumps into the car and they drive off.

“Who are you running away from anyway?”

“It’s called the ‘institute’. They took me prisoner to have sex with their clients.”

“Well, you were probably asking for it, getting those breast implants and running around naked. In my days, we had more decency.”

Sister Riley tries to not argue back. All she needs to do is stay in the car, no need to anger the old woman any more.

After a short ride, they see men with uniforms and guns standing at the side of the road in some distance ahead of them. The old woman points at them.

“Ah, there are some policemen. You can get out of there and then you are their problem.”

“No, they are from the institute. Fuck, I gotta hide. Don’t let them see me.”

Sister Riley quickly unbuckles her seatbelt and pushes her seat all the way to the back, which allows her to slide down to her leg room, where she huddles to a ball. Her tits are poking out the side and her guts are in agony with her body folded onto the toy, but she grits her teeth and endures the pain, in order to hide.

The men in uniform see the old woman in the car and wave her through. After a few minutes, sister Riley tries to get back up, but the old woman insists that she stays down, so she can’t cause any more trouble.

After 20 more minutes of bumpy roads, they finally stop at a house. The old woman fetches a blanket from the trunk and covers the girl, so they can both go inside.

Once the door is closed, sister Riley urgently asks for some scissors, so she can finally cut the leather straps. As soon as they are cut, the dildo shoots out of her ass and crashes onto the ground. Sister Riley groans in pain and relief, holding her ass, which is still gaping open.

The old woman is in shock.

“That thing was in your behind? Why would anyone do that?”

“How often do I have to tell you? The institute did this to me. If I enjoyed it, why would I have cut it loose?”

“I don’t know, don’t ask me that. I’m not the weird woman running around naked.”

Sister Riley sighs and tries to compose herself. Don’t fight her.

“You are right, I’m sorry and also very thankful for your help. However, I have one more favor to ask? Do you have some clothes and some food, please? And do you mind if I use your bathroom and shower?”

“Go ahead, better not make anything dirty in here.”

While she enjoys what seemed like the best shower in her life, the old woman puts some old clothes into the bathroom, which sister Riley gratefully changes into. They meet in the kitchen, where they eat a warm soup that she slurps down eagerly. Afterwards, she tries to come up with a plan.

“Ma’am, thank you for your hospitality. I understand that it was not easy to trust me. So, I think I should not overstay my welcome and better leave. The more distance I get between me and this place, the better.”

“Don’t worry about that, young lady. I have called the police. They will come soon to help you take care of that man that kept you prisoner.”

“You called the police? I’m pretty sure they work together with the institute. It’s not just one man. It’s an internationally operating network working with powerful men. Oh no … they know I’m here. I have to get going right now!”

Sister Riley quickly sneaks to the window and already sees cars approaching them. The main door is too dangerous now. She runs for the backdoor and jumps over the garden fence. While still scared for her life, she is so relieved to be able to run with nothing up her ass. Unfortunately, her escape does not go unnoticed and the men in uniform start chasing her.

She reaches a street and keeps running as fast as her legs allow it, but the men are getting closer. When she is about to collapse, a van stops in front of her and two men with rifles jump out, running towards her. With her lungs and legs burning, she is at the end of her rope, and she only manages to fall to the ground, holding her arms in front of her as if they would provide any protection from gun fire.

However, the men from the van run past her and start shooting into the direction of her pursuers. A woman emerges from the van and beckons sister Riley.

“Get in, quick, let’s not risk a shootout!!”

What is going on? She picks herself up and uses her last ounce of power to jump inside the car. The two men follow suit and shut the door, whereupon the van drives off with squealing tires.

“Are you hurt?”

Sister Riley can hear her, but she can’t talk. All she can do is breathe and give a thumbs up.

“Don’t worry, you are safe for now. They can’t chase us, because they left their car when they followed you through the garden. We are driving to our headquarters, where you will be able to rest. I’m Hellen. What’s your name?”

“Hi Hellen. I’m … sister Riley.”

“So, you are from the institute.”

“You know about the institute?”

“Only bits and pieces. Maybe we can learn more from you. I have never met someone who managed to break out. When we heard from the police radio that someone escaped, we immediately came in order to help you.”

“Thanks, that was a close call. But where are you taking me? What is your headquarters? Do you have an army?”

“… no, we are only a small handful of people, operating from the mansion of Baron Tomslay. He finances our group.”

“Then I should thank him, I suppose.”

“Don’t worry, you will get the chance to meet him soon.”

The car eventually reaches the mansion and the group is welcomed by an old man eagerly waiting at the door.

“You actually got her out! What a relief! Oh dear, you must be scared stiff. Please, come in and get some rest. Welcome to my home, I’m Baron Tomslay.”

“Hallo, Mr. Baron Tomslay, I’m … they call me sister Riley. Thank you for helping me.”

Once they are inside, she gets more comfortable clothes and they ask her to lie down on a bed with her head over a scanner device for accessing the chip in her brain. While computer specialists try to decipher the device, sister Riley and Baron Tomslay continue their conversation.

“You were quite ambitious with your escape. Were you born in the institute or in the outside world?”

“In the outside world. They abducted me when I was 18 and modified my body to look female. I have been a slave ever since.”

“A slave for … sex with the clients? That must have been grueling.”

“For sex, yes, but eventually I got used to it. Having sex with them wasn’t that difficult.”

“Dear heavens, that sounds like there were even worse things happening to you.”

“Try getting fucked in the ass by a 45 cm (17.7 inch) horse cock almost every day. It doesn’t get harder than that.”

“Good grief, that is dreadful! I’m so sorry to hear that. But you are safe now. As a matter of fact, you could help us bring them down. Would you be willing to testify against them and to provide information for our fight against the institute?”

“I owe you my life. Of course I’ll help you. Let’s give them hell!”

“I admire your resolve after all this time, thank you. I don’t know if we can change your body back to a male one. The breast implants may be removed, but I can’t promise you anything more.”

“That would already be a great start. But don’t worry about my body. This may sound weird to you but … I feel more female than male anyway. I don’t really remember what it was like to be a man. They altered my brain too long ago. I don’t think it can be reversed.”

They continue their conversation, talking about the inner mechanisms of the institute and possible plans for attacks. He also gives her a gun and explains how to protect herself with it. After some time, the computer specialists say that the chip appears to be deactivated.

However, meddling with the chip may have given away their position, as some time after scouts sound the alarm about incoming vehicles. The group manages to leave the premises in a van, but after a short car chase are eventually blocked in the back and the front by a jeep. Driven into a corner with no escape, the group gets ready for a shootout, until suddenly father John steps out of one of the jeeps.

“There is no escape for you all. And even though it appears you won’t let the girl go to save your life, I’m not so sure if she would want to risk your life on such an unwinnable gamble. Don’t you think, sister Riley?”

When she unbuckles herself, Baron Tomslay holds her by the sleeve, gesturing her to stay inside. But sister Riley knows that father John is correct. She can wait in the car until everyone gets shot or face him on her own accord. She breaks loose from Tomslay’s grip and exits the car with raised hands.

“I’m coming out. Don’t shoot. Let them be … do you still think I am too considerate of others, father John?”

“I do. But I’m glad you came out without force. It wouldn’t be worth risking the life of my men to bring you back. Still, what a waste of time. And you were wondering why I still wouldn’t trust you.”

“What, father John? Are you nervous, because you lost control?”

“No, I have control over you, don’t you remember?”

He pulls out his remote and presses a button, whereupon sister Riley collapses motionless to the ground. Father John walks up to the girl that gave them the trouble and shakes his head.

“What a nuisance. Alright men, get your stuff and pack her up so we can …”

He is uninterrupted by a loud bang and collapses to the ground. Sister Riley is breathing heavily, still pointing her gun at him. Hurry, get up, his men haven’t registered yet what happened.

She quickly jumps back into the van and screams at the driver to break through the jeep barrier. He steps on the gas and forces the car through the blockage, toppling the jeeps. Once they are through, they can hear gunfire behind them, but with the enemy unable to chase after them, the noise eventually fades with distance.

After checking that nobody was injured, they celebrate sister Riley’s victory and plan to drop her off at a safe house that is an hour drive away. Sister Riley is told to stay put until Baron Tomslay contacts the authorities.

Once they arrive in an underground parking lot, sister Riley and Baron Tomslay take the elevator to an upper level. The elevator doors open to a luxuriously decorated hallway, in which they are welcomed by familiar faces.

“Surprise! Did you miss me?”

Sister Riley is mortified. They are back at the institute and in front of her is its staff with … father John. She runs to the elevator panel and presses any button trying to close the elevator door, but they are not moving. With wide open eyes, she backs into a corner and curls into a ball. Father John is alive? He is not even injured. Was she given a fake gun? Who gave her the gun again? It was the group in the mansion of … the baron. Where is he? Oh no, he is talking with father John! They are laughing. They were no enemies? Was everything just a show? Oh no, it was a trap, she should not have jumped into the van. She should have run into a different direction.

Wait, who else is talking with father John. The old lady from the car! She was part of the setup as well? Did they plan all that? How much did they plan?

She can’t run anymore, so she may as well face them directly. Sister Riley crawls out of the elevator towards the laughing group of people.

“What just happened? Who are these people? Father John …?

“These are two of our clients, who paid a lot to play a part in your escape attempt.”

The baron is smiling to the old woman.

“But it was well worth it, wasn’t it darling?”

“Yes, my dear, it was so exciting. I felt like I was in a movie, but more real. Oh, when she was begging to get into my car … exhilarating … I still get goose bumps.”

Sister Riley in disbelief.

“But father John, how did you plan it? How did you know that I was escaping?”

“We unlocked the door in the pool room in order to give you access to an escape path. Once we knew that you had familiarized yourself with the window and you had enough time to come up with an escape plan, our guests stayed a few days, waiting for you to take action.”

Sister Riley is in utter shock. They planned everything from the very start. The door was intentionally unlocked. They wanted her to escape, to give her false hope. But, the plan was missing a trigger…

“But how could you know that I decided to escape? I could have done it now or half a year later.”

“That was indeed a bit of a gamble. If you had waited too long, we would have had one of the managing sisters pretend to help you. But luckily that was not necessary, because our client’s daughter was helping.”

“Their daughter? Who do you mean? How did she help?”

The baron speaks into his phone.

“Did you hear, darling? You can come in; this is your cue.”

A door opens, and a young woman walks in slowly, with a gloating smile. Sister Riley gasps at the surprise guest. Bela! Of course, she had tortured her about how meaningless sister Riley’s life is. She wanted to provoke her escape … and she succeeded.

“It worked exactly as planned. We live streamed everything for our clients and it was a massive hit. The only thing we didn’t plan was you trying to trick our hounds by masturbating into the bushes. When we saw in our cameras what you were trying to do, we told our men with the dogs to fall back intentionally in order to make you think it would work. People went crazy watching you try to repeat it a few more times.”

“You always knew where I was?”

“Of course.”

“What about the trucks that went past me?”

“Our men. As well as our street. The search group with the dogs was pushing you towards that particular street. Because it is our private street, there would not have been any traffic. But by making some trucks pass you first, we ensured that you would try your best to get into the car of our client.”

“And the chip in my head?”

“Was never deactivated. But here it gets interesting for me. When I pretended to use the remote, I assumed that you would be surprised by nothing happening and then eventually realize that you can use the gun. But I underestimated you. You already pretended to be immobilized, which means the moment you got out of the car, you had planned to kill me.”

He was absolutely right. She intended to kill him and now she is back at his merci. She is back to being powerless after showing what she would have done if she had power. What will he do to her now? What can she do?

“I’m … sorry, father John.”

“Right, you are sorry that you didn’t really kill me. But I can’t hold it against you too much, as you were set up to do that. And the terror in your eyes, when you realized what happened … that alone made it worth it to me. That spark of will power that you showed by your escape skyrocketed your value. We have months of reservations from clients who want to be with you already, which is good for the institute. But first in line, are our two clients who were part of our play.”

Father John turns to the old couple.

“Have you decided what you want to do?”

“Yes, my wife saw how much she hated the toy in her ass, and the slave told me that the horse is the most difficult thing for her. So, we decided to go forward with option C, the picnic.”

“Great choice. Please, come with me, I’ll explain the route. And sister Riley, clean yourself, you need to be ready for action in 20 minutes.”

Sister Riley watches the three people walk away still talking gleefully about their experience, when a managing sister grabs her by the arm and pulls her into the elevator in order to get back to her chamber. She is showering in the same apartment as before, which indicates that she has not lost her privileges yet, but it feels so much more like a prison after having tasted freedom, or at least an illusion thereof. She breaks down in tears, but still manages to finish cleaning in time.

When she comes out of the bathroom, father John and the couple are already waiting. He hands her the big dildo and instructs her to force it into her ass. Once it is crammed inside, the toy is attached to her with straps and locks, for which the couple gets the key.

Father John has spread out on a table all sorts of food and eating utensils and asks the couple what they want to bring for the picnic. The old lady feels like a kid in a candy store.

“Oh, we need a blanket, a thermos of tea, some silver cutlery, some croissants, jam, some paper plates. Look, they even have caviar…”

Sister Riley is instructed to go on all four, allowing father John to put the ***********ed items into the hollow lumen of the toy in her ass. Once it is jammed full, it is closed with a screw cap and the group goes outside, where her stallion and two other horses are saddled up. Sister Riley can barely walk with the heavy toy in her ass and groans in pain when she is lifted up on her stallion. Even when she finally manages to sit on top, her ass does not stop hurting as almost all of her weight is on the toy abutting against the saddle. She grinds her teeth, trying to deal with the pressure in silence.

However, when the group of horses starts to trot, she can’t contain her screams of agony, as she bounces up and down with every step of her stallion. The elderly couple is unperturbed, enjoying the sight of the beautiful nature, pointing out grazing sheep and flying birds to each other, while hearing the screams of torment from the person that had raped their daughter so many years ago.

After half an hour, they reach a flowery meadow with trees and a metal frame, which sister Riley recognizes all too well. Once they are off their horses, the old lady unlocks the straps and sister Riley is allowed to expel the dildo from her ass. She then has to set up the picnic right next to the metal frame while the couple is appreciate the beautiful scenery.

Once everything is in place, they tell her to bring her stallion to the metal frame, so she can get fucked by him. Soon after, the couple enjoys some hot tea with all sorts of luxurious snacks while listening to the wailing of their picnic basket getting ravaged by the horse.

Eventually, they start conversing with her, while the horse is still going to town on her.

“We had such a blast, watching your attempt to escape. Say, when did you think you could make it? Was it when you had roped down from the window?”

Sister Riley feels humiliated, having to recount being tricked by everyone. But she can’t walk away from the conversation and answers truthfully, speaking in the rhythm that the horse is thrusting.

“No, I first thought I had a chance, when I heard alarms, but was already out of sight of the institute. That is, until I heard the hounds barking.”

“And then you tried to get them off the scent, by jerking off into the bushes. Haha, to be honest, I also thought that would work.”

The old lady slaps her knee laughing at her husband, who shakes his head.

“It would not work, Elisabeth. Think about it, the trail of scent is not interrupted. The hounds can just keep chasing.”

“Oh, you are right! I have to keep this in mind, in case I ever get chased by dogs, hahaha … anyhow, when you met me in the car, what were you thinking? I was so worried that I messed up the ***********. I haven’t practiced that much since school, hahaha.”

“It was frustrating having to fight your hostility, as you were my only way out.”

“Hah, yes, I almost felt sorry for you. Oh, I wish my scene was longer. But eventually, you left the house in order to meet Richard.”

“Was the house even real? Was the village real? What about the huge mansion?”

“Oh, those were real, but they don’t belong to us. The house was father John’s and the mansion belongs to the institute. We will be able to stay the night there, after they removed all the props. They did a great job, didn’t they, Elisabeth? it looked so real!”

It sounds like they are talking about a movie. Sister Riley is getting irritated by their disconnect from reality.

“What do you mean, it looked real? I am a prisoner and I did try to escape! This is real!”

“The only reality that I am accepting is that you raped our only child and that you are punished for it. We may as well make it our entertainment.”

“But this is out of proportion. How is this fair?”

“No, it’s not, which is exactly what we wanted and what we were able to afford.”

Sister Riley stops arguing. She realizes that it is not about what’s right or wrong, but about power. And that trivial question needs not be discussed.

After some time, they give her a large plastic cup, because she starts leaking horse cum out of her ass. She is allowed to step away from the horse and empty her ass. Once she has downed everything and the couple is done eating, sister Riley has to clean up the picnic and put the rest into the dildo, which goes back into her ass.

The ride back is even worse for her, as her ass is completely sore from being stretched and fucked constantly. Back at the institute, the old couple is welcomed by their daughter, while sister Riley falls off the horse in exhaustion and pain. Bela walks up to her, promising the key to the leather laces once she has jerked off into her mouth.

It takes her forever to come, due to the painful dildo in her ass and the three people watching her dismissively. After she finally swallows her load, they throw the key on the ground and say goodbye forever.

This was indeed the last time she saw them, but not the last time she was mocked for her escape attempt. Father John was right. For months afterwards, there were masters who saw the video footage and sought her out. Some wanted to ask her about her experience, some wanted her to insert the giant dildo, some wanted to visit her escape route with her. She got fucked under the rock in the forest and the mansion. Ironically, being forced to relive it over and over eventually made her numb to the misery and once her emotional pain was gone, so was the interest of the masters.

Gradually, she got back into her routine of receiving masters and streaming live shows. Once her penis reached a length of 30 cm (11.8 inches), she didn’t even have to use the machine on her dick anymore. But other than that, nothing new happened in her life. At least for some time.
