After the brief, acrimonious conversation with his sister, Scott headed back to his bedroom. Closing the door behind him, he sat down on his bed playing the scene with his mother as she stepped out of the shower in his head over and over. His cock, which had immediately softened when he argued with his sister, was hard once again. Remembering how it felt the first time he watched his mother, the time she was with her half-ass boyfriend Jason and Scott got caught watching them from his mother's closet. It all seemed so oddly natural as she had Scott join Jason and her in the bed. She let Scott fuck her that afternoon and the memory of that sensation still burned in his mind.
It was even a turn on for Scott to watch Jason go down on mom and eat her cream pie. Seeing Jason's face glittering, spotted white with Scott's sperm was really strange and arousing. Letting the images of that afternoon join with the memories of maybe forty five minutes ago when he kneeled down and ate her newly shaved pussy, Scott opened his pants and began to stroke himself.
It was beginning to feel pretty good and he was about to rush into his bathroom to grab something so he could clean up after he came when he heard his sister say something to their mom and then rush out the front door. With his hard cock still sticking out of his pants, he moved over to the window and watched his sister drive away. Almost immediately he heard a quick knock on his door and then his mother slipped into the room.
Scott just stood there not even trying to cover himself up as his mother said, "She'll be gone for just a few minutes, but I didn't want to leave you like this." She walked over to him and grasped his cock, stroking it firmly. "Were you jacking off thinking about what we just did?"
Scott nodded.
Smiling she said, "It was nice, I only wish we could have some more time so we could really make love."
