My sister’s flatmate – Chapter 06 – Liz learns to obey

Chapter 06 – Liz learns to obey

I was once again visiting Liz. It’s always a pain in the ass discussion to find a weekend where we are both free. For me it’s easier to get to her but in my flat we would have more free time for ourselves then in her shared flat. We had discussed the anal topic via chat. She still doesn’t like the idea of something in her butt or to even touch me there. I of course respected that but since she no longer forbid me to even touch her anus I planned to continue touching her there until she becomes more comfortable with it.

I met Liz in the city center. She stayed a bit longer at university and I picked her up there. We drove to a nearby Chinese restaurant to have dinner. The restaurant was nearly fully booked since it was a Friday evening. Liz and I searched the menu for some nice food to our liking. Once we ordered Liz was going to visit the bathroom.

“Take your purse with you and text me once you are done.” I said vigorously when she stood up. She looked a bit confused but obeyed. We had also talked briefly about BDSM. I’m a bit of a switch but she would only want to try submitting. We hadn’t made any plans about this yet and I wasn’t planning to have a real session with her however I want to figure out if I’m able to order her around a bit. I haven’t had any real life experiences with being a Dom at that point in time. As far as I know she also hasn’t had any experience with subbing. Her ex boyfriend never pleasured her sexually but she stayed with him for quite some time. I wonder if that was an indication for her submissiveness.

“I’m done and coming back now.”

“No. Stay in the cabin.”

She had one of those giant purses where she also could fit in her university books. I slipped a little present into it while we were in the car. We talked about our previous adventures and she told me how much she liked the outdoor plays. The thrill of getting caught and the fear of accidentally flashing.

“Search your purse. You will find a small present in the outer pocket. Text me once you put it in its place.”

The present was a vibrating egg that can be controlled via my phone. I paired it with my phone back home and added a very small bag of lube into the packaging. It took Liz a while to text me back. I already feared that I had gone too far.

“Done. Thanks for the lube.” I was a bit relieved.

“Good. Now turn it on and hurry back. Drinks are already served.”

I watched on my phone until I saw that the toy was connected.

“Oh and put your panties in your purse.”

When Liz came back from the bathroom she was a bit red in her face and I noticed that she walked a bit differently. She wore very tight black leggings and a white shirt that covered her ass. It was not a typical Liz outfit and didn’t give me any chance to validate if she actually wasn’t wearing any panties. When she arrived at our table she placed the purse next to her chair.

“Cheer’s” I said with a big smile on my face and grabbed my glass of wine. Liz was taking a big sip before she put her glas down again. Liz was sitting with her back to the rest of the room.

“Should I put your purse next to my chair? That way it’s not in the way and nobody can steal it.” I said with a wink. Without a comment Liz handed me her purse and I quickly checked the outer pocket. Happily I found an empty packaging and a black thong. I smiled at Liz and put the bag down.

“Did you read the piece of paper?” I asked her. She nodded and drank another big sip of wine. I also had added a little note to the box to tell her that I never tried the toy before. I also wrote down a safe word for her. “Lasagna” a word that nobody would use in s Chinese restaurant but which also should be very memorable for her because it’s one of my favorite dishes which she already prepared for me multiple times in the past.

“Do you remember the word?” I asked as confirmation. Liz nodded again.

“Say it.”

“Lasagna” she whispered.

“Good.” I smiled happily and switched to some Smalltalk.

In my lap, out of sight for Liz, I started the control app on my smartwatch. While Liz was talking about the past week and what she had experienced in university I started the vibrator for the first time at only about 10%. Liz stopped talking for a few seconds and continued afterwards like nothing had happened. While we waited for our food I played around a little bit with the vibrator. Liz was obviously getting aroused by it. Her nipples became a little bit stiff and her Dekolleté red and sweaty. From time to time she moved on her chair, or closed her eyes. For me it was obvious but others wouldn’t notice. The vibrator was a little bit hearable at 70% so I tried to stay under it. Liz was already making big eyes every time I came close to those 70%. She obviously had no idea that another 30% are yet to come. I added a few short vibration patterns to the shortcut list on my Smartwatch. One of those was really close to the typical smartphone vibration pattern. My idea was that nobody would pay attention even if they hear it from time to time. When I saw the waiter arriving with our food I turned off the vibrator. But when he stepped to our table and handed Liz her food I activated the pattern with 100%. The sound was very hearable and if you pay attention you could also hear the difference to a phone. But nobody except Liz paid attention. Her shocked o-face was maybe the biggest indicator for something happening. The waiter looked a bit worried for a second but handed Liz her food. As soon as he wasn’t looking at Liz anymore and handed me my food, I activated the pattern again. This time Liz played it a bit cooler. She still made this weird looking o-face for a part of a second but other than that she played it cool. For the time where we are eating I had prepared a long running pattern that stayed all the time below 50%. I only want her wet but not yet cumming. I was pretty sure that Liz wouldn’t cum from this anyways. She really needs some stimulation at her clit to cum. But the vibrator egg is obviously not delivering that kind of pleasure to her. After we were done with the dinner I was pretty sure that Liz was horny enough to do some more things for me. We got in the car and changed the settings before I turned on the engine. The toy had a mode where it would translate actual speed into the strength of the vibration. Meaning it will vibrate at 100% when I drive fast and it’s turned off when I stop the car. Of course I haven’t told Liz about this feature.

“How do you like your present?” I asked while we are still in the parking lot of the restaurant.

“It feels really good. Thank you. But there wasn’t any need to try it out in a fucking restaurant.”

“Didn’t you like it? I bet you are pretty wet!”

Liz blushed.

“Of course I am. I have a fucking vibrator inside me for over an hour. I really would like to pull it out and press it against my clit. But no way I gonna do that in public.”

I laughed about her reaction.

“Exactly you are not taking it out. But I have another task for you. I want that you cum. But not at any time. I want that you cum while we are driving on the road you are living at. Not a second earlier and also not when I parked in front of your flat. Do you understand?”

Without waiting for her approval I started the engine and headed towards her flat. The vibrator started right away and gave Liz some pleasure. We chatted about this and that until I stopped the car at a red light.

“It wasn’t a joke Liz. I want that you cum. Do you understand? You better put your hands in your leggings and get to work.”

“But I can’t masturbate while we drive through the city. What if someone sees me?”

“Nobody can see your lap from outside the car. They won’t notice.”

“But still, I don’t …”

“Liz!” I interrupted her, “we both know that you are really wet down there. Am I right?”

She shrugged but didn’t answer me. Since the traffic light was still red I moved my hand under her shirt and into her leggings. She didn’t resist at all. I could feel her wetness and had the confirmation I needed. I looked into her eyes.

“Liz.” I said way more relaxed now, “we both know that you like this.” I started to tickle her clit a bit which got me a moan as response. “You don’t have to deny it. It’s not bad that you like it. It’s actually kinda hot and really turning me on. So please don’t be so scared. You don’t seem to have a problem with me playing with you. But I have to drive us home. So you have to finish the job for me.” I pulled my hand out of her short and hold it in front of her face. Without me saying something she licked the fingers clean. The traffic light turned green and I had to concentrate on the road again. When I looked at Liz the next time she had one hand in her leggings and closed eyes. I smiled but didn’t say anything. But at the next red traffic light I interrupted Liz.

“Good girl. But next time I want that you do something like this without a discussion. And to help you remember that I want you to give me your bra.”

Liz looked at me but didn’t dare to say anything. She removed her bra under her shirt and placed it in my waiting hand.

“Good girl” I said with a smile and stored her bra in the door pocket. “Don’t forget that you are only allowed to cum when I turned into the street you are living at. Did you understand that?”

“Yes. But why are you doing this to me?”

“Because I know that you like it. And I like it too!” I grabbed my hard cock through my trousers and gave it a quick rub “You know what? You could actually do something for me!”

“What can I do for you?” Liz asked scared.

“You can flash me your breasts. Lift your shirt for me Liz.”

“No way!!! Someone will see me, it’s way…”

“Liz. Relax. Look around. There is no other car around us. And also no pedestal. If you don’t do it now you might have to do it at the next traffic light with people around.”

Liz’s eyes wandered around on the street searching for people. When she realized that nobody was there she pulled her shirt up for the quarter of a second.

“Liz. Try again. Until I say you can take it down again.”

She pulled it up and I looked at her wonderful perky full tits. I grabbed the left one, which was closer to me. I massaged it for a second before I pinched in her nipple. Short but hard.

“Aua!” Liz screamed.

“I told you, that you should stop arguing with me.” The traffic light turned green and I started to drive forward. This triggered the vibrator and made Liz moan. In the middle of the crossing I told Liz that she can pull her shirt down again. When she realized that we started driving she blushed and hectically searched for someone who might have seen her. We continued the drive and Liz continued to play with herself.

“It’s only two more minutes Liz. I hope you are getting close.” This was a rhetorical question. Liz was breathing heavily and her hand was moving rapidly. Her eyes were closed and her mouth a bit open.

Due to Liz’s closed eyes she didn’t notice that I switched lanes at the last crossing. Instead of turning right into the street Liz lives at I’m turning left. Onto the highway. When I accelerated I could hear the vibrator at 100% and Liz shocked moaning.

“You…oh fuck… drove wrong.”

“No. I never said we would drive to your flat yet. Remember that you are not allowed to cum.”

Liz removed her hands from her leggings and pushed herself a few centimeters out of the chair.

“Fuuuuuck. I’m cumming.”

“No, you are holding it! It’s only two more exits.”

“At least drive slower.”

I slowed down for a moment only to accelerate afterwards and overtake some other cars. Liz was breathing heavily all the time. Whenever I accelerated she inhaled very sharp. She got way more relaxed when we took the exit and the car slowed down. From the exit it was only a minute or so before I stopped the car at a parking lot near a forest.

“I thought after having dinner we might want to go for a walk.”

“That’s a nice idea, but I would have preferred to do some other things at home.”

“What other things do you mean?”

“You know what I mean! I’m super horny right now! And that is your fault! I want you to fuck me!”

“I will. But not now. Now we are having a walk.” I said and got out of the car. Since Liz didn’t join me immediately I walked around the car and opened her door. She sat in the seat, arms crossed before her chest and looked a bit mad at me.

“Haha, you are the first girl that is mad at me for not fucking her. Get out of the car Liz.”

When she shook her head I pinched into her right nipple and pulled at it.

“Ouch ouch ouch, okay okay okay!” She removed the seatbelt and swung her legs out of the car. As soon as she stood on her feet I let go of her nipple.

“See, it wasn’t that hard.”

I used the free hand to turn on the vibrator again. She moaned out and stared at me with a slightly opened mouth. I reused the pattern from the restaurant to give her a constant stimulation and keep her horny.

“Please not” she asked between two moans. She crossed her legs and pressed them together. I grabbed her hand and started to move.

“Let’s walk. You won’t notice it anymore when you are distracted.”

We walked along the trail and met other people from time to time. All of them were heading toward the exit. None of them noticed Liz’s stiff nipples or my constant erection. I really had to hold back so far. Multiple times I was really close to just grab Liz and fuck her. But my plan was a different one.

It was getting late and the sun would soon be gone. We climbed to the top of a little hill which gave us a nice view. We sat down on a bench and watched the sunset. The place was kinda open. We had the forest behind us and a little slope in front of us. So nothing was blocking the view towards the sunset. We could see the sun slowly going down behind another hill.

Liz was leaning against my shoulder and it was super quiet. I could only hear some birds, Liz’s breath and very quiet the sound of the vibrator. I needed to laugh out loud when I noticed it.

“What’s up?” Liz asked.

“Nothing. I just heard this very quiet buzzing sound.”

Liz jokingly hit my leg.

“Do you still want to cum?”

“Yes of course! But it’s easier now. It’s not stimulating me enough to bring me close to orgasm.”

“Good. Do you like the view?”

“Yes a lot. Thanks for going here.”

“I’m also enjoying it. But there is one thing that would make the view even nicer.”

“What is it?”

“It’s you Liz. Get up and move over there.” I pointed to a place a few steps away. It was close to the slope and from my perspective directly in front of the sun.

“Did you just call me beautiful in your own weird words?” Liz asked while getting up.

“For sure. You look gorgeous Liz. Move a little bit to the left. Perfect. Do you mind if I take a picture?”

“Sure do it.”

I started a 5 second timer in the camera app. When there was only one second left I increased the vibrator to a hundred percent. That way I got a beautiful memory of Liz’s moaning face. I turned the vibrator off afterwards.

“Okay Liz. I feel a little bit left behind. You are getting all the satisfaction and I’m just sitting here completely unsatisfied. Maybe you can show me your gorgeous tits.”

Liz looked a little bit confused at first. Then her eyes started to scan the forest behind me. When she made sure that nobody was there she flashed her tits for half a second by lifting her shirt.

“That was not what I meant Liz.” I said annoyed “Throw your Shirt over to me. I want to enjoy the sundown while watching your tits.” As I expected she started to hesitate.

“What if someone else sees me?”

“Then they are very lucky. But I don’t think anyone will hike up here that late. So either you throw your shirt over or I will rip it off your body and you have to drive home shirtless.”

Slowly Liz pulled her shirt above her head. Slowly she was revealing her beautiful tits to me. Once she was done she tossed it over to me and I placed it next to me on the bench. Liz then tried to cover her beautiful tits with her hands.

“Liiiiiz. Put your hands behind your head please.”

After hesitating for a moment she did as I asked and presented her stiff nipples to the cold air. I enjoyed the silence and the view that was presented to me. The sun is slowly going down behind Liz and shines through her slightly spread legs. Only now I realized that there was a giant wet patch between her legs. I opened the zipper of my trousers and pulled my rock hard dick out of it. I started to stroke myself while my eyes wandered over Liz’s body. From time to time I started the vibrator to hear the beautiful moaning sound from Liz. My eyes then always wandered to her face to watch the moan escape her mouth. Her eyes on the other side were glued to my cock.

“Get on your knees. Hands stay where they are.”

Liz looked to the ground. It was mostly dried soil with a few rocks in between.

“Please not, that will destroy my leggings.”

I hadn’t thought about this to be honest.

“Then get out of your leggings first.”

Being completely nude was something else then just being shirtless. So I expected Liz to protest. I was really surprised when she didn’t do so. She looked down to the ground, breathed out heavily and started to get out of her leggings. It took her a moment before she was done and had thrown it over to me. When she continued to get to her knees I stopped her.

“No please keep standing for a moment. I want to enjoy the view.”

The sun was still shining between her legs and created a nice silhouette of her pussy lips.

“Play with your pussy.”

This time she didn’t hesitate at all but moved her hand to her eagerly waiting wetness. After watching her for a few moments I got up and stepped towards her. I gave her a long kiss during which our tongues played with each other. I grabbed her tits and gave them a good massage. I caressed her nipples and gave them a few pinches. I could feel and hear that Liz was getting closer and closer to an orgasm. To protect her from reaching it I grabbed the hand that was playing with her clit and slowly moved it away. She tried to resist at first but quickly gave in. I also grabbed the other hand and moved both behind her head.

“Now get on your knees.” I said and pressed her head down. I didn’t need to say anything more. She instantly closed her lips around my cock and started to bump her head up and down my member. I couldn’t really believe the moment and the luck I had. I was standing at the edge of a slope and watching a nice sundown while a beautiful naked girl was giving me a really nice blowjob. Liz was really trying everything to get me to a fast orgasm. Her tongue was playing with my head and from time to time she also tried to deepthroat me. I could feel my head touching the back of her mouth for a moment. Then she started to gag and retracted. I think she really was training her gag reflex with a dildo at home. Picturing her doing so was bringing me another step closer to the edge. I was getting really close but I didn’t want to cum in her mouth this time so I pulled myself out of her mouth. She watched a little bit irritated at me when I grabbed my cock and started to masturbate. With a few quick strokes I reached my orgasm. I pointed my cock at her tits and coated them with my cum. When I was done my cum was glistening orange in the setting sun.

“Do you have tissues on you? I left mine in the car.” Liz asked when I helped her get up.

“No I don’t. Just leave it dry for a moment.” I responded and guided Liz to the bench. “No, not yet.” I said when she was reaching for her shirt and her leggings. “Let it dry first. We don’t want to ruin your shirt right?”

After we sat down we watched the last few minutes of the sunset. Liz put her head against my shoulder again and I had my arm around her, resting at her waist. I gave her a few moments to relax before I turned her vibrator on again.

“Oh God, not again. Please!”

I only grinned and moved my arm from her waist to her crotch. She opened her legs and invited my hand to further explore. But I already had a target: her clit. It only took a few touches before she was close to the edge again. I stopped and let my hand travel along her pussy towards her wet hole. I inserted a finger and felt the vibrator buzzing in her.

“Okay let’s go.” I said as soon as the sun was gone. I pulled my fingers out of Liz and licked them clean. Liz, as always, rolled her eyes when she saw that. But she grabbed her leggings and started to get into it. When she leaned forward her breasts were dangling so nicely I couldn’t resist, grabbed them and played with them a bit.

“The cum is still wet so better no shirt for you.” I told her once she was done and grabbed for her shirt. I took it from her and led her back to the path from which we came. I was a bit surprised that there was no argument with Liz. Maybe she got used to it by now. It was quickly getting really dark and the path downhill had no lights. We used our Smartphones to brighten the way at least a bit. In general I can advise you to not walk down a hilly forest in the night. Wasn’t that much fun. Once we reached the main path there were streetlights every now and then. When I heard voices in the far distance I gave Liz her shirt back which she took thankfully. My cum was still visible in her cleavage but no one would notice in the dark. When we reached our parked car we fell into the seats. Exhausted from the long day, the hike and all the activities. But at least Liz wasn’t done yet. As soon as I started the car, I also activated the speed based mode at her vibrator.

“Oh really?” She asked “I’m done. I don’t have any more energy for this.”

“You still have your mission. Cum when we reach the street you are living at.”

“I’m too exhausted, I can’t.”

I turned onto the highway and accelerated the car and the vibrator.

“Oooooh fuck.” Liz moaned.

“Sounds like you can. But better hurry it’s not that far.” I reached over to her and kneaded her left breast for a moment. Then I pulled down her cleavage and exposed the breast.

“This stays out until we exit the highway. And now start.”

From the edge of my view I saw Liz’s hand moving inside her leggings. A few seconds later her moaning gave me confirmation. The ride was rather short. There was little traffic and we reached the exit in only a few minutes.

“Okay Liz, we are nearly there. Are you ready?”

“Oooooh yes.” She moaned.

We stopped at the same traffic light at which we had stopped earlier.

“Okay Liz, as soon as it turns green you are allowed to cum.”

She looked at me and nodded. Her mouth was slightly open and a moan was on her lips.

“Oh and by the way Liz. It’s not that I care, but we are off the highway for a couple of minutes now and your tit is still out. She instantly blushed and pulled up her cleavage hiding her beautiful breast from my view. The light turned green a few moments later. I accelerated the car slowly. Liz moaning also accelerated. It became faster, louder and more intense. It was really hard to focus on the traffic and not on the masturbating girl next to me.

“I can already see your house Liz. Remember, when you don’t cum before we arrive you will not cum at all today.”

“I can do it. Oooooh fuck.” Liz was really working on her clit to make it possible. I drove a little bit slower than I could to give her a little bit more time. And also to take a quick look at her. Her face was kinda sweaty. Her mouth was wide open and her eyes closed. Her hair was a mess. Her nipples were poking through her shirt. She had pulled it a bit up with her left hand, which revealed her belly and gave me a good view of her right arm. It was buried deep inside her leggings and it was clearly visible that her hand moved very fast inside. A few moments later Liz came. It was one of the biggest orgasms I ever saw. Liz moaned so loud that a person outside of the car would have been able to hear her. Her left hand let go of her shirt and she supported herself by placing it at the dashboard. Her body center was twitching rapidly. And her right hand continued to rub her clit. The whole orgasm lasted a minute or two and I safely parked the car during it. When Liz came down from the wave she realized where she was and quickly scanned her surroundings for any person who might have spotted her. Of course there was no one. She blushed in her own innocent way. She wasn’t saying anything and looked down in her crotch. She slowly pulled her cum covered hand out of her leggings. She looked at it for a few moments before the wiped it clean at her leggings.

“You did great Liz. Let’s move upstairs and get you a shower.”

Liz only nodded and I got out of the car. While moving to the passenger side I turned off the vibrator. I opened Liz’s door and helped her out of the car. She wasn’t stable on her legs so I assisted her and carried our bags. I helped her climb the stairs and went into the bathroom with her. I placed Liz on the closed toilet, started the shower and adjusted the temperature to her liking. I got her out of her shirt and out of her leggings. I quickly got nude as well before I helped her get on her legs again. I walked with her in the shower and put her under the hot water. When I was sure that she was standing safely I kneeled down and looked at her destroyed pussy. I touched it briefly but stopped instantly when I noticed Liz’s reaction to it. I reached towards her opening and slowly pulled out the vibrator. It was covered in her pussy juice. I tossed it to the side. The water would clean it. I got on my legs again and helped Liz clean her whole body. My cock was half stiff the whole time but I had no intention to fuck her in her current state.

When we were done I dried Liz and put a large towel around her to move her into her bedroom. We got into bed directly and Liz dozed off to sleep a few moments later. I watched her sleep for a while. I still couldn’t believe the luck I had to find her. I also fell asleep a few moments later.

When I woke up the next morning Liz was still asleep. I silently moved into the kitchen and prepared breakfast for us. While doing so her flatmate Ellie came freshly showered into the kitchen. Shit, I thought. I normally always sleep in the living room when her flatmates are around.

“Haha. Don’t worry. Liz has told me.”

My shocked face must have been more obvious then I thought.

“And I also won’t tell your sister if I can get some of the scrambled eggs.”

“For sure you can. No need to blackmail me.” I laughed.

Ellie and I did a little small talk. She was a nice looking girl too. Her still wet brown hair was up in a bun. She wore a white blouse and a black skinny jeans. The blouse had a decent cleavage revealing a good part of her medium sized breasts. I remember them smaller so I guess she helped a little bit to make them look bigger.

“Going on a date?” I asked her?

“Yes, I’m meeting that guy from university.”

“You look great. Enjoy!” I said while leaving for the bathroom.

“You two too.”

While sitting on the toilet I noticed the pink vibrator still laying in the shower. “Fuck” I said silently and laughed. There was no way Ellie hasn’t seen it when she showered. Maybe she had even used it. With the pink toy in my hand I made my way back to the kitchen. On the way I thought about what to say to Ellie but luckily she was gone when I reached the kitchen. I felt really lucky to be able to avoid talking with her about this. Maybe she also doesn’t want to talk about it. I placed the toy on the trail next to the coffee cups and headed back to Liz’s room. Liz was awake now and texted on her phone. She quickly threw it away and moved to the side when I placed the trail on her bed.

“Good morning” I said with a smile.

“Good morning! Thanks for the breakfast. How did I deserve that?”

“You did really great yesterday.” I answered with a wink. Liz blushed. She blushed even more when she saw the toy laying on the trail.

“Why is this here?” She asked while grabbing a cup of coffee.

“We forgot it in the bathroom yesterday evening. Ellie has seen it but I haven’t talked with her about it. But I figured out that you have talked with her about us.”

“Yes I have. I’m sorry I should have told you.”

“Don’t worry. What have you told her?”

“Not much. Just that we are friends with certain benefits. She asked for details but I didn’t gave her any. I also talked to my other flat mate. Both promised to not tell your sister. So at least for the next few months we are safe.”

(My sister is still in a foreign country in case you forgot)

“Good.” I said. I already could feel my cock harden again. Liz was still not wearing anything and while we talked the blanket had revealed one of her breasts. But I wanted to talk about one more topic.

“How did you like yesterday?”

Liz blushed.

“A lot” she whispered between two bites of egg.

“All of it?”

She thought a bit about it and then she nodded.

“You know that I did it because you added ‘submission’ as one of your kinks in the app, right?”

She nodded again.

“I also really liked my role and I’m planning to do it again.”

Her eyes became big.

“Don’t worry it might be different. And it might be in one of our bedrooms instead of a car. But I also will try other things of your and my kink list. However you can always make it stop by using your safe word. Do you understand that?”

She nodded again.

“But can we also have normal sex?” She asked.

“Haha of course. We can and will. Actually most of the time we will have normal sex.”

“Okay good. Because I like that as well.” She said and turned towards me kissing me.

“Me too. But I have one more request.” I said with a smile after our kiss. Liz looked with big waiting eyes.

“Get out of the bed, kneel down and thank me for the breakfast with a nice morning blowjob.

Liz didn’t waste a second, jumped out of bed and got to work.
