Several days had passed since I had found out about my sister. That day, I had took her virginity and gave her the first blowjob she had ever had. In my mind, I knew that what we did was wrong by society’s standards, but I couldn’t get over how right it felt. I loved Avery with all of my heart. Don’t get me wrong. We were siblings and like all siblings, we had our moments of discontent. But I would do anything for this girl. Mess with her and you mess with me. Piss her off and she’s not the one you need to worry about.
Yet, here I was, the one who had made the move on her. I was the one who instigated the events that led to us having sex. I was the one who couldn’t wait to do it again. There were a few girls in school that I had casual relationships with: Friends with benefits, if you will. I could call them up practically anytime and we’d go out and end up screwing. It wasn’t like I needed to fuck Avery just to get me some. No, it was much different than that. It’s like she was vulnerable. Like I needed to do it to help protect her, yet let her experience that part of life. From what I know of high schoolers, if her secret got out, she’d be ostracized and shunned. She was way too popular and outgoing for that to happen.
At lunch, I grabbed my tray and headed towards my usual table. Avery and a few of her friends were already there talking.
“Hey Tim.” her friend Susan said as I sat down. “What’s new?”
“Not much Susan. How about you?”
“I have the feeling Avery has a new boyfriend, but she denies it.” She looked at me hoping to gain some sort of inclination or information.
I opened my soda can and answered without even looking at her. “No, not that I know of. When would she have had time to find a boyfriend?” I looked up at Susan. “If she’s not in class or at home, she’s with you. So I should be asking you who this new guy is.” I glanced over at Avery. She sat motionless and not saying a word.
Susan contemplated what I had just said. “I guess you’re right. It just seems that she has been way too happy these past few days. I know I only get that way when I have a new love in my life.”
I glanced over at Avery again. She smiled briefly then looked away. I thought about what Susan said. Avery did seem to have a little extra pep in her stride. Could it be possible that she felt the same way about what had happened? I let the thought slide from my brain as I went back to eating my lunch.
Classes finally ended for the day, and being that I had no practice or anything going on, I walked to my car were Avery was waiting for me to give her a ride home. I unlocked the doors with the fob and then got in. As I began pulling out of the parking lot, I turned to ask her “So who is this new boyfriend of yours?”
Avery laughed. “Oh, I think you’d like him. He’s sweet and kind and really hot.”
I glanced over at her. “You think I’m hot?”
Avery feigned embarrassment. “Who said I was talking about you?”
“Okay, okay!” I conceded. “But seriously. Aren’t you the least bit freaked out over what we did?”
Avery turned to face him. “Tim, you stood up for me. I appreciate that. You asked to see my condition when I told you about it. I could have said no, but you sincerely were interested, so I stripped down and let you see.” She continued on. “Besides, what did I truly expect you to do with a naked woman on your bed? Play Mario Cart?”
Tim laughed at the notion. “I guess yo’re right. I know other people would blow their lid if they knew what we did, but I can’t say I regret it.”
“Neither do I.” she chimed. “I just hope it wasn’t a one and done kind of thing. I owe you for the orgasms I had.”
Tom smiled at the memories of their time together. “So what do we do when we get home?” he inquired.
“Get naked and play shark attack.”
“Shark attack?” he asked.
“Yeah, you lay down and scream while I eat you.”
Tim couldn’t get home fast enough. His cum gun was hard as a diamond and about to rip out his jeans. He pulled into the driveway and shut the car off. They both ran into the house and straight to his room. Both were peeling off clothes as they headed towards the bed. When they got there, Avery turned towards him and pressed her lips against his. He continued to shed the rest of his clothes, dropping his pants and his boxers. He unhooked her bra and then slid his hands down to remove her shorts and panties. Both of their cocks were hard and battling each other in a fencing duel. Avery turns him towards the bed and pushes him down forcing him to lie back. She drops to her knees and takes his engorged member into her mouth. Tim feels her warm, moist mouth wrap around the head of his cock. Avery sticks out her tongue and laps it along the underside of his shaft as she goes up and down. She draws her tongue back in as she continues to take all of his dick into her throat. The lust and excitement of the moment has his balls tightening as he can’t hold on any longer. He grips the bedspread in his hands as he lets out a loud and extended groan. His cock spasms in her mouth as he jets several shots of semen into her wanting mouth. Avery moans in pleasure as she sucks and swallows every last drop. She holds still with his prick in her mouth as she lets the after cum sensitivity die down, then she begins cleaning the last few bits from his semi flaccid pecker.
“I love the taste of your cum. I’ll suck you off anytime you want me to brother.” She crawls up on the bed beside him. Tim looks into her beautiful eyes. Man how he loves her.
“That was awesome, Av. My mind is blown.”
“Don’t you mean your cock was blown?” she said playfully. Then her face got serious. “Tim, how does it feel to stick you dick inside of me?
He pushed himself up on his elbows. “It’s kind of hard to explain. You feel this pressure all around your shaft and it is pretty good.”
She sits up and looks at him. “I was just wondering.”
Tim thinks for a moment. “How ’bout we do something special now?”
Avery looks at him puzzled. “What could be more special than what we’ve been doing?”
“Well, if you want to, I’ll let you fuck me.” he offers.
“I already have fucked you, Tim.”
He shakes his head. “Hey, you’ve let me fuck you, but you haven’t fucked me.”
The idea registers in her mind. “Are you serious? You’d let me stick it up your ass?” She couldn’t believe what she was hearing.
“I know how it feels when I get inside of you. You should get the same opportunity to feel that.”
“Are you sure?” she asks. “I mean, that’s a big step for any couple.”
“Yes, I’m sure. If you want to, then I’m good with it.” Avery still sat there not sure she heard him correctly. Tim sits up and reaches for the lube in his nightstand. He squirts out a glob and rubs it all over her penis. He then grabs her finger and squirts some on it.
“You’ll have to loosen me up a bit, but I’m ready.” He gets on all fours as he crawls to the center of the bed. Avery moves around behind him and sticks her finger into his tight asshole. The lube is cold, but the exhilaration of her finger poking into his puckered anus is maddening. She slowly works one finger in, swirling it around and wiggling it back and forth. She then pulls out and reinserts two fingers, widening his virgin hole. Soon, she has three fingers in and is knuckles deep. Figuring she has him prepped, she readjusts herself and lines her cock up with his sphincter. She meets a little resistance as her cock pushes forward, but gently pops into his rectum.
“OOOOOhhhhh?” Tim exclaims. Her shecock is stretching his virgin anus. She slides in a bit further touching his sensitve prostate sending shivers throughout his body. “Oh shit, that feels good.” Avery is also moaning. The feeling of his tight rectal muscles gripping against her womanhood are sensational. “Oh, fuck, Tim!” She pushes in even deeper. She finally has her pelvis pushed up against his ass cheeks. She begins to gyrate back and forth, savoring the felling of her penis against the inside of her brother’s bowels. Tim’s cock begins streaming pre cum as Avery massages his male g-spot from the inside. She pulls out and tells him to roll over. Now on his back, she pushes his knees back towards his head and places her girl cock in his gaping butt hole. She resumes stroking her brother in and out,as her pace begins to quicken. She begins to feel a twinge in her abdominal cavity. She can feel her testicles begin to spasm inside of her. She keeps pumping him, gaining more speed and momentum. The lust and the pressure are too much for Tim. Without even touching his rock hard tool, he begins to shoot sperm everywhere. The first shot lands on his chin. The second flies up landing in Avery’s hair. The next few hit his chest and stomach, then the rest just dribble down the side of his cock. Avery is too busy feeling her own orgasm coming on to even notice. She thrusts hard into his ass. She pulls back and thrusts forward again, this time holding tight against his buttocks. Her rigid phallus pumps stream after stream of hot jizz into Tim’s ass. They both held still for several minutes just breathing hard. Avery finally falls down on his chest. She notices the puddles of cum and begins to wipe them up with her fingers and direct the wayward spooge into her awaiting mouth.
“Oh, Tim.” she breathed out. “That was the best cum I’ve ever had. Even better than the other day.” Tim reached over and grabbed a tissue and wiped the cum from her strawberry locks.
“I’m glad you liked it.” He grabbed ahold of her hips and rolled her over on her back, ending up between her legs. “Are you ready for another one?”
She looked down at his still hard penis. “If you are.” she countered. Tim grabbed the lube, put some on his dick and some in her canal. He lined up his head and inserted it between her plump lips. He gently worked his shaft into her pussy. Avery closed her eyes and enjoyed the effects of their intercourse. Tim began driving into her. He pushed her legs further up to get deeper into her. Her knees were by her head and she was doubled up. As he kept stroking he pushed her legs even farther. Avery opened her eyes and saw her dick was close to her chin. She stretches her neck and bobs her head down taking the end of her cock in between her lips. Tim watched as she begin blowing herself. Avery was sucking and licking her pee hole as it flowed with precum. The sight was too much for Tim, He began pounding her small frame as hard as he could. Avery let out a loud, muffled scream as he saw her cock convulsing and her cheeks being pushed out by her own cum. He let out a loud scream himself as he once again shot his wad in her tight little cunt.
As Avery came off her orgasm, she let her cock slip out of her mouth and swallowed most of the cum in it. Tim dropped down on top of her, placing his mouth on hers and sucking out whatever was left on her tongue. He pulled away from the kiss.
“Damn, Avery! How in the hell did you do that?”
“I don’t know. I just saw how close it was and did it.” Her eyes as full of astonishment as his.
He rolled off of her and laid beside her. “If you could only fuck yourself, then you wouldn’t need me.”
Avery thought about what he said, reached down bending her cock and sliding the head inside of her cunt. She could just barely get it in due to the angle.
“Looks like it’s a possibility, but I’d rather share these times with you.” She rolled over on top of him and began to kiss him again.
They laid there for a while, caressing and kissing. Finally, she got up and told him they should get cleaned up before their parents got home. They each headed for their own shower where they made themselves presentable. When both were dressed, they made their way down to the living room and sat together on the couch, watching TV.
“Avery, I love you.” Tim muttered. “In fact, I think I am in love with you.”
Avery snuggled up close to him. Without looking up, she said “I’m in love with you too, big brother. Do you think I could be your girlfriend?”
Tim didn’t hesitate to answer. “Baby, I’d love for you to be my girlfriend.” He lifted her head up and kissed her sweet lips. “My secret, sister girlfriend. Never, ever thought I’d ever say that.”
Avery snuggled back into his chest. “I think we are gonna be the best brother and sister duo ever.”
Tim smiled at the thought. He was as happy as he had been in a long time. Too bad he couldn’t share it with his buddies. They just wouldn’t understand.
