John Wakes, Takes Advantage

The sun cracked on John's eye as he opened his eyes to curiously find his penis out of his pants. He could smell the dried semen on the shirt, but couldn't think of doing anything the night before. Standing up, he pulled up his pants and opened the door.

Walking down the hallway, he peered into Sams room which was usually closed. Coming on the door, he was shocked to see her half naked on the bed. From his view, he could clearly see her milky white ass. With hastening breath, he took a couple of steps closer to see that she did indeed not have any panties on.

His cock was starting to harden at finally seeing what he had fantasized so many years ago. He stopped to hear that she was in deep sleep. Also quickly noticing the vibrator, long since it's batteries died, sitting at the entrance of her pussy. He picked it up, with the initial intention of putting it on the dresser, only to get curious and bring it closer to his face. At first, she smelled it and inhaled the musk of her scent. Sticking his tongue out, he licked one side to the other effectively cleaning the excess. His cock was throbbing with each breath he took.

The blood was rushing to his other head fast; convincing himself that she wasn't going to wake up, he unzipped his pants to fish out her iron hard dick. He gave it some strokes while staring intently at Sam's pussy.

After a few moments of his heart racing and quickening breath, he thought there would be little harm in putting himself in her. He went back and forth, in the end instinct won. John slowly got on the bed and positioned himself over her on his hands. Taking one hand, he spit on a couple of fingers and rubbed it on the head. Taking his cock, he rubbed himself into her.

It was like being in a dream. Sam's vagina gripped his dick like a heated vase. He was already pistoning into her for all he was worth. It didn't take long before he was ready to cum.

At this point, Lilin was coming to her senses. "Mmm" she said out of Sam's mouth without opening her eyes. "Keep it up big boy."

John's brain was suddenly alerted to her being awake, while the last thrust put him over the edge. John couldn't take it and started to pump his sister full of cum as he held his hips down. Lilin felt it come and clinched her pussy tightly. While the first squirt coated her womb, but Lilin was sure to collect the rest into her essence.

While her pussy was very sore from the night before, the fresh batch of semen gave her a boost.

John quickly got up and apologized before stumbling out of the room. Pitiful, Lilin thought. She could try to condition him but first her stomach started to make noises. Guess humans have to eat.
