Their parents were off work the next day, so they stayed up later than usual. Their horny children were tortured enough, let alone having to wait. Jeff spent the evening fighting a hard on, Amy grew wetter and wetter with each passing minute. She mischievously changed into her ‘sleepwear’, which consisted of – loose blue hospital pants, and a white T-shirt that showed off her belly. Her panties accidentally were revealed above the pants, and ‘oops’ – they were pink with dark pink hearts.
Then she came back downstairs and smiled at him, knowingly. By 9pm, they were both climbing the walls with arousal, and both were racking their brains for a reason to be alone, as they watched TV with their father in the recroom. Their mother watched TV alone upstairs. Finally, their dad went upstairs, either for more beer, or to go to the bathroom, or both.
No sooner was he out of sight then the two siblings were on each other. They kissed passionately, his hand immediately going down the front of her loose pants and into her panties. He slid his fingers through the curls of her pubic hair, finding her slit. She was so incredibly wet, he couldn’t believe it! Her own hand went down to his crotch, undoing his jeans and reaching into his underwear. He slid his tongue far into her mouth as he slid his finger into her tight hole. “Mmmmph…” she moaned as her fingers wrapped around his shaft.
She pulled out his cock and broke the kiss, bending towards his lap. She flung her hair out of the way, and he was able to watch his cock disappear into her mouth. He was forced to take his hand out of her panties as she sunk her lips down his shaft, touching her throat with his member. ‘Slurp slurp slurp slurp slurp’ she slurped loudly and eagerly on his manhood.
“So what’s my surprise?” he asked as she gave him head. She pulled him out of her mouth with a ‘slurp’ and appeared to think for a second. Her hand habitually stroked his penis.
“Ummm…okay, I’ll tell you one of them.” She said, “last week when Bonnie was over we talked for like an hour about lesbians. I think she really liked it, and was turned on, though she would never admit it.” His cock seemed to grow incredibly hard in her hand. “And,” she went on, “she is coming over this weekend and I’m
going to get her really drunk and put the moves on her then. I think I can include her in our fun soon!” His heart was pounding as he looked at her incredulously.
He grabbed her, roughly spun her around onto her hands and knees on the couch. She was silent, smiling, as she let him have his way with her. He grabbed her pants and forced them down to her knees, revealing that skinny ass of hers, barely covered by those skimpy pink panties. Straddling her legs, he ripped those panties down, joining her pants at her knees, revealing her ass, and the quivering pink pussy lips beneath. He held out his rock hard pole, touching her slit. She was so wet she practically sucked him into her tightness.
“Ohhhhh…” she let a moan escape as her brother’s 6-inch penis entered her all the way in just one stroke. Her ass was pressed against his groin; he was in her so deep. Her pussy was so hot around him. Wasting no time, he grabbed her skinny hips and began to fuck her as hard as he could right away. She grabbed a pillow and buried her face in it, moaning loudly into it.
He slapped hard against her, unable to control himself. ‘Slap slap slap slap slap’ his groin made her ass cheeks shake with each rapid impact.
“Mmmmph! Mmmmph! Mmmmph! Mmmmph! Mmmmph!” she moaned. He was fucking her so hard. Lucky for both of them their father was called into the living room by their mother, else he would have come down and perhaps caught them. She was helpless, her brother had her in a tight grip and he was thrusting forward as fast and as hard as she could. She couldn’t breathe, but she couldn’t move the pillow because her cries were too loud. “Mmmmph! Mmmmph! Mmmmph!” she cried.
He was losing it. The thought of fucking his other sister really setting him off. He thrust into Amy a few more times before sliding into her all the way, holding it there.
He looked down at her ass pressed against his groin. It was at this point where they were at the complete mercy of their parents. If they chose to come down, Jeff and Amy would be caught. Jeff was cumming, and at that point, he had no control and couldn’t stop. His cum fired out the end of his penis and deep into his sister’s vagina. He moaned, ejaculating deep into Amy’s womb.
That moment, their father headed for the door to downstairs where his son was shooting semen into his daughter.
More of his seed fired violently out of Jeff’s penis and sprayed off the back of Amy’s pussy.
Their dad reached for the doorknob.
Jeff’s cum continued to trickle out of his cock and into her hungry, needy vagina. They heard the door upstairs open. Jeff pulled his cock out of his sister with an audible ‘slurp’ and ran into the laundry room, doing up his pants. Amy merely pulled her panties and pants up and sat down, pussy full of her brother’s cum. Their dad entered the room, oblivious to what had happened, and Jeff came walking innocently out of the laundry room, just ‘checking on his laundry’.
Their dad ended up staying with them until just after midnight. Finally, both parents went to bed.
“Now for your other surprise.” Amy said, getting up and going upstairs. Her pussy was tingling with excitement, she was all flushed, and her heart was pounding. She grabbed the jar of Vaseline and rushed back downstairs, subtly hiding it behind her back. She was determined, no matter how much it hurt her, to let him fuck her up the ass as long and as hard as he wanted.
