Jeff uncomfortably crossed his legs to hide his erection. What Jenny didn't know was her whole acting like a baby was slowly turning him on. In fact when she soiled herself moments ago and that bulge appeared in the back of her disposable pants, a different but equally large one had formed in the front of his.
It was all Jeff could do not to stroke himself at the sight of such infantile beauty. He thought he could contain it and keep his arousal hidden until it went away.
But then the smell hit his nose.
The pungent odor that made many mothers and babysitters cringe or groan upon smelling, instead made him grow excited as his penis hardened, now straining against the crotch of his jeans.
Unable to resist the urge Jeff moved his hand to lightly rub his bulge, closing his eyes and moaning as he did so. Realizing his actions too late he opened his eyes to see Jenny staring at him.

"Wanna have your way with a 2 year old in a very dirty diaper?" Jenny asked in a seductive fashion.
The baby girl then turned around to bend over and stick out her messy diapered rear end, rubbing the bulging back with her hand while looking over her shoulder at him with a wink.
Jenny always did know just what to say and do to send his engine into overdrive. Between the display coupled with the heavy stench that hung in the air Jeff felt like his cock was going to burst right out of his fly.
Wordlessly getting up from his chair he had just enough sense to quickly lock his bedroom door so his parents wouldn't accident walk in and see what he was about to do.
