Jenny and Benny slept in Benny's bed, exhausted, after several more rounds. Bill marveled at the sexual stamina of his son and daughter, remembering similar events between him and his wife... events which would never happen again. Lauren, his wife, was changing for a while, changes which scared him. His wife had been turning into a man. But then the changes stopped, as abruptly as they had begun. She was just a woman with a little boy's genitals.
A few hours later, as Bill was lying in his bed (their bedroom; Lauren had let him back in), Jenny came in. "I'm horny, Daddy." She said in her sweet voice, and the innocence of her angelic face was completely destroyed by the next thing out of her mouth. "Can I fuck you? I don't mind Mommy watching. Please, Daddy?"
This was part of their game. Her asking and acting coy made him wet before they began. "I won't be too hard on my little girl." She smiled widely, and jumped up onto the bed, grinning at Lauren before pulling Bill's sleep pants down (he hadn't worn underwear, and never did anymore, when sleeping) and pushing into him.
Bill bucked and swayed with her, stroking her hair and moaning as she fucked the twenty-eight-year-old man's eight-year-old pussy as hard as she could. Lauren watched them curiously, pulling on her twelve-year-old penis with one hand, the other hand playing with her nipples.
He'd forgotten about Jenny being with Benny by then, his mind too consumed with lust and pleasure, focusing only on the now, on Jenny filling his pussy almost to bursting, thrusting in and out, stretching him to his limits. She finally exploded within him and withdrew, leaving him dripping cum and his own juices, staring at the enormous cock attached to his cute eight-year-old daughter.
His eyes barely noticed a sticky note stuck to the ceiling, and though he couldn't see it, he still somehow read it out loud...
