It was midnight when Jen heard the door to her room open. She shoved her face into her pillow with a loud groan. "Not right now Dan!" She shouted into her pillow. "It's late and we have a test tomorrow! I for one want to graduate senior year." Her brother Dan ignored her and walked to the edge of her bed where he sat down and rested his hand softly on her back through the thick comforter.
"Come on sis, you know I need to masturbate before bed, it's the only way I can go to sleep and I have the same test that I need to wake up for."
"Can't you just go use mom?" Jen said, still talking into her pillow. She refused to come out of her soft and warm blanket cocoon unless there was no other choice.
Dan shrugged and said "Dad is fucking her right now and they don't like to share at night. Something something "respecting privacy and the privilege of marriage" and other such bullshit. C'mon sis, I will be quick just need to rub one out before bed."
Jen groaned one last time into her pillow before she finally flipped over and looked up at her brother. They were twins and the 6 months since they turned 18 taught her one very important lesson. When it came to fucking her brother was never, ever, quick.
"Dan if you could be quick I would just have raised my ass and let you have your way. But you and I both know you won't be satisfied until you fuck all of my holes at least once. Quick for you means we are done by 1am at the earliest and we both have to be up at 6:30! That's not enough sleep!"
"Look I know it's late but I was up studying! And you know I wont sleep well if I can't cum."
"Studying? Or playing video games. Cause I am pretty sure I heard Jeff on discord bragging about getting to claim Sarah over the weekends when I went to the bathroom an hour ago. I seriously doubt you guys were studying" She raised her arms from the covers and gave him air quotes for the word studying which caused the blankets fell away from her oversized d-cup tits that defied gravity with the power of youth.
They were her proudest feature and on her small and skinny 5'6 frame they seemed twice the size they actually were. Of course that immediately drew her brothers attention and Jen knew with a tinge of regret there was no way she was getting out of sex now. Not that there was much of a chance of it before.
Staring straight at her tits now that they were exposed Dan mumbled sheepishly "I was just taking a break!" Dan looked back up at her eye's and said "Look if I could just jerk it myself I would but you know the law. Masturbation needs a partner and you are the only cocksleeve available in the house right now."
Jen sighed and threw off her covers revealing the rest of her athletic and firm body. She was one of the star runners on the track team (mainly because it was the only free time she got without a cock inside of her as most of the track boys were not fast enough to catch her) and it showed in her toned legs and tight shapely ass. Her long blond hair cascaded over her shoulders as she leaned over towards him. Her sapphire blue eyes stared into his and her soft fingers wrapped around his already hardening cock.
"Next time just don't be so late to come and use me ok? You know how much I need sleep and it would mean a lot to me if you could be a bit more considerate in the future."
After saying her piece she wrapped her lips around the tip of his thick 9 inch cock and began to suck and lick him, starting her blowjob slow. She could still taste her mom on him from when they were having dinner.
Dan groaned in pleasure when she went down on him but seemed mortified when he said "You got it sis, I will try to go to bed earlier myself. I promise."
She doubted he would fulfill the promise but she had more pressing concerns. Mainly trying to deepthroat her brothers cock. He had one of the biggest cocks in school, especially in the girth department at almost 3 inches wide, and was pretty popular with the other girls as a result. That meant she didn't get to practice on him as much as she would like despite living with him. He was the only guy she knew that she still had trouble deepthroating.
"Fucking hell Jen. It's only been 6 months since we turned 18 and already you give the best fucking head in our class" Jen would have smiled if she could but her mouth was stretched wide has she fed inch after inch of him into her gullet.
She decided tonight was the night she would fit his entire cock in her mouth. She took pride in her abilities as a fucktoy and regularly practiced the cunt and ass exercises they taught in school to keep them tight as she could despite the large number of cocks she took every day. Her throat ln the other hand got practice all on it's own as most of the boys in school loved to fuck her mouth. She was one of the few who could already deepthroat regularly in their grade.
Dan took a handful of her hair in his fist and gathered it at the back of her head as he got ready to help her get him past that final hurdle. She felt her pussy begin to heat up in anticipation of the hard throatfuck she knew was about to receive.
