Jason Gilbert was feeling very disappointed as he lay in bed. For the first time in over a week, there was nobody in bed beside him. On the rare occasions when he had slept in his own bed either his mother, or one of his two sisters, had always crawled under the covers beside him. More often than not, the entire family had squeezed together in his mother's Wyoming King. The previous night he had fallen asleep in between his mother and his grandmother, all three of them drenched in sweat and both women full to the brim with his cum. Now he was a alone, and while he did wish his family could spend at least some time doing normal activities together instead of just fucking, he was quickly realising that he didn't enjoy the feeling of empty space beside him in the bed anymore.
His youngest sister, Sophie, had decided to spend an extra night at their father's house for some reason, which is why she hadn't joined Jason that night. Unfortunately, he knew that neither his mother Alison or his older sister Sarah would be arriving into him any time soon either. Sarah was currently sharing a bed with her best friend Megan, a stunning ebony beauty who was in town for the weekend. They had offered to set up Sophie's room for their guest, but she insisted that she didn't want to impose and that she was well used to sharing a bed with Sarah from their early college years. Both Gilbert women were afraid that Megan would hear any incestuous activities, and so Jason would have to wait until the next day before fucking his mother and sister again.
It didn't help that Megan had been flirting with him all evening. Jason had never been with a black girl, and Megan was particularly stunning. He often found himself feeling stupid next to the soon-to-be law school graduate, since every time she had asked him a question he had stumbled over his words. The problem was that he couldn't stop staring at her. She had incredible plump lips that screamed 'amazing blowjobs'. Though not as big as Alison's or Sarah's, her tits were definitely on the huge side and the crop top she was wearing had clearly given up any hope of hiding them. When she had gotten up from the table to hug him when they first met, he saw that she was wearing an extremely tight pair of yoga pants and showed off the perfect curves of her ass. Megan was clearly a fitness fanatic, and although Jason usually preferred BBWs like his mother and sister he couldn't help but admire the sculpted muscles of her body. Particularly her abs and thighs. He kept getting a vivid image of his cock spraying white cum all over the midnight skin covering those abs. Usually right before Megan asked him something and he had to scramble to find words aside from 'I want to cum on you'.
Perhaps she had noticed his fascination with her. Perhaps that was why she kept touching him, his biceps and shoulders, complimenting the muscles and asking about his workout routine. He left out the part where the only cardio he had done for the last week or so had been ploughing every woman in his family. She also asked a lot about his love life, whether he had a girlfriend in college and insisted that they should meet up for a coffee sometime when the next semester started. Jason was non-committal about the coffee. He could see the jealousy flaring in the faces of his mother and Sarah, especially Sarah. He thought his sister's jealous face was cute, and he wondered how upset she would really be if he took her best friend up on the offer of coffee.
Now though, he was alone in bed absent-mindedly tugging at the pole between his legs. Ten and a half inches of rock hard cock ready to fuck, with no waiting holes to welcome it. He replayed his incestual trysts in his head. The first time he and Sarah had hooked up, his mother squirting all over him and his grandmother while they fucked, the taste of Sophie's tight teen cunt as she came on his face. Then Megan joined his fantasies. She was everywhere. She was throwing her ass back on his cock in doggy while burying her face between Sarah's thighs. She was 69ing with Sophie, licking his balls as he pounded his little sister. She was sucking on his mother's gigantic tits while Alison impaled herself on his cock. No matter what he imagined, though, it brought him no closer to cumming. Thinking back, he realised that this was the first time he was jacking off since the first month of college nearly a year ago, after which the rumours about his endowment ensured a steady stream of willing partners. Not to mention the week long incest fuckathon he had just been on. His cock was too used to the good life, and wasn't interested in orgasms that didn't involve at least one partner.
"You've been spoiled." he muttered at his member, before turning off his bedside lamp and trying to go to sleep.

Sometime later he awoke to the feeling of a warm wet mouth enveloping the first two-thirds of his cock. He let out a contented moan, as quietly as possible, delighted that either his mother or his sister had been unable to resist a sneaky fuck. They would have to be extremely careful to make as little noise as possible to avoid Megan hearing them, but he was too horny to stop the amazing blowjob he was getting.
"Mmmmmm that feels so good, I was hoping I'd have company tonight." he moaned gently.
He slid his hand under the covers to try and find his lover, guessing that she was kneeling by the side of the bed. His fingers touched the soft flesh of a breast and he began groping the large mammary. Then he froze. The tit he was feeling was much, much larger than his little sister's A cups, which ruled out the idea that Sophie had snuck home for a quickie. On the other hand, it was definitely smaller than his older sister's KK cups and far smaller than his mother's mind-boggling P cups. With a start he pulled the covers off the bed and flicked on his bedside lamp. There, kneeling beside his bed with over half his cock stuffed down her throat, was Megan. Despite his shock he couldn't help but admire the contrast between her ebony complexion and the pale skin of his shaft.
"Megan what the fuck are you doing?" he whispered.
"What the fuck does it look like I'm doing, Jason?" she whispered back once she had pulled her mouth from his cock. "I'm sucking off this big white cock."
His head fell back onto the pillow as she resumed bathing his manhood in her saliva. Her tongue felt incredible, working magic along the veins of his tool and making him struggle to keep quiet. Any fear that his mother or sister would catch them was overwhelmed by horniness. He continued massaging Megan's breast until he felt her remove his cock from her mouth again.
"Wait a minute," she said, her eyes narrowing as she jacked him off with both hands, "if you were surprised to find me swallowing this monster cock then whose company were you hoping for tonight?"
He remained silent, unable to think of any good excuse. He watched as the realisation dawned on Megan's face.
"Oh. My. God. It's Sarah, isn't it? You're fucking your own sister!"
Jason glanced towards the door, half expecting to see Alison or Sarah barging through. Megan, understanding his feeling of panic at her outburst, lowered her voice again.
"Fuck me, I always suspected that she was a freak in bed. But her own brother? That's a new level of fucked up to me." she whispered, still furiously stroking Jason's cock. "Then again, having this fucking weapon in my hands I can't blame her. Did it start before or after Ethan dumped her?"
"After." he answered, not quite believing that she was still wanking his prick.
