In the past couple of weeks, Bill had come to enjoy the sex he had with his daughter Jenny. Her cock filled his little pussy wonderfully, and he was glad for the first time that she'd gotten his huge cock and he'd gotten her little girl's pussy. The pleasure of being filled so completely was far greater than he'd ever gotten with his cock, and she was insatiable. Every couple of hours when she was home from school she came up to him and, wherever he was, fucked him relentlessly. There wasn't a room in the house they hadn't had sex in by that point.
He was going through the house as he usually did, checking on his family, and saw something surprising in Benny's room. The two of them were lying together in Benny's bed, and Bill's heart sank as he saw that Jenny's cock was inside of Benny; they'd obviously had sex, and though Jenny had told him about her friend Nina who sucked her off every day at school, this was very unexpected. His daughter had had sex behind his back, and with his son, no less.
Jenny looked up at him and waved, smiling. "Hi, Daddy! Benny's really fun to fuck, almost as much as you." She cuddled up closer to him, and Benny moaned, rubbing his leg against hers and pushing back and forth against her. They scrambled back into a better position, Benny laying under her as she pulled out of him and then thrust herself back in, heedless of their father watching with a finger inside his tiny pussy, rubbing and pushing and moaning quietly.
