You lust after her and jerk off that night.

Laying in bed that night, John realizes that he can't keep her off your mind. Remembering back to earlier in the day, he thinks of how soft she looked and her potential to become truly chubby. Maybe even fat. Or bigger...

John imagines what it would be like if she had walked into that classroom today looking different. Fatter. You imagine her waddling in, easily 3 times her size with a fat paunch overhanging over her pants, which themselves were still too small to fit her thunderous thighs and much rounder ass. Her arms would be puffed up with with fat, and tits nice and round, fat enough to for two hands to barely cover one. The shirt she would be wearing have no hope of covering her stomach, pulled tight across her much larger round breasts.

As she waddles in, her entire body would seem to jiggle and shake, her eyes on John with a wink on her way to her seat. Just like earlier today, he would of course find himself needing to shift in his seat to hide the growing erection from the sight of her alone, much less the way she moved, and her fat too. To make matters worse, since she sits nearby, John'd never be able to keep your eyes off her for very long. He'd simply drink in how her belly would gently fill her lap, her wide ass overflow the sides of her chair, how her puffy fat arms would always push against her round... fat.... tits...!

John cums, and cums hard, finding himself **** to use a nearby t-shirt to even clean up the mess.

This is wild, right? Every time he jerks off lately, he seems to cum more than before. And Anna? Is she... from his...? Nah, that's impossible.

Right?

These thoughts continue to linger in the back of John's head as he finishes cleaning up and turning over to sleep for the rest of the night.
