On his way home from school Friday afternoon, Jack discovered a short cut. Usually it took him forty minutes to get home, but after cutting through a few back yards, he was home in only twenty. This was pretty cool, because his mom and dad were always out until at least midnight on fridays, and he liked to have the place to himself, well except for his younger sister, but then she usually stayed in her room or went to a friend’s for the night.
He arrived home, eager to check out the new porn website his friend had told him about, and headed straight to his room, his nineteen year old cock already hardening and ready to go as he passed his sister’s door.
“Ooooh god yes!” Jack froze when he heard Sammy moaning in her room. He waited a minute, nothing but silence, and then; “So….so good.” Was his fifteen year old sister getting laid? He usually wasn’t home for another twenty minutes, so she clearly thought she had the house to herself. Curious, he quietly pressed an ear to her door. Samantha was panting and moaning, whispering little ‘yes’s and ‘oh god’s. And it was unbelievably hot, so much sexier than the actresses he watched in pornos. His young cock shot straight up at the alluring sound, and he began to rub it through his jeans as his sister sped up her moaning, clearly working up to an orgasm.
“Oh god yes..Yes….Oh so good ahhh…ahhhh…..YESSSS!” She actually screamed as she came, and just the sound almost made him come too. He was still standing there, rubbing his prick when he heard the bed springs creak and realized she was standing up, so he quickly slipped into his own room down the hall.
Once alone in his room, Jack dug quickly through his desk until he found a recent picture of Sammy, and masturbated furiously, coming almost immediately, shooting his jizz all over the photo of her face.
