“Cum for your Mommy,” Jill begged. She couldn’t believe how incredible sex with her son was. “I need to feel your cum in me! Fill me up, give it to me, oh hurry!” Her body was demanding more, suddenly she shouted, “Spank me! Spank your dirty Mommy! I’m so dirty, fucking my son, begging for his cum, oh Tim! Punish me! Spank my ass!”
Hearing his Mommy beg him for his cum, for rougher and rougher sex did the trick. Tim felt his balls pull up under his cock. “All right Mommy, you want it? Here it comes!” Tim started slapping his Mommy’s ass-cheeks as he fired his hot jism deep into her hungry womb. Jill felt his cock swell inside her, her orgasm got stronger, it was like they were somehow becoming perfect for each other!
Inside the rutting pair, at the cellular level, tiny nanobots swarmed their systems, rewiring their bodies and brains. They had been passed to Tim from his mother’s mouth, now they were being tuned to each other. Soon they would be each other’s ideal sex partner. In the other room on Tim’s desk, The Thing dissolved into dust and blew away.
