"S-Sarah!!" My former voice squeaked out in anguish as I slid a finger in. "N-Not in-"
"You're the one who didn't wear my panties today." I whispered into my former body's ear with a grin. "You're gonna squirt all over the store, aren't you, you little slut?"
"Sarah!! S-Sttttttttahpppppppp!!" That cute voice moaned as its legs shook, my new fingers drenched in the sweet nectar Mike was making in my old body...
Swap Class. Most people are absolutely terrified of it. A week in another body, your own used however your partner wants. Poor Mike was out "sick" when everyone grouped up. And ever since a former teacher abused a student's body, I didn't have a partner. The only one in the class without one. When Mike showed up the next day, he bitched and moaned about swapping with me. Apparently I was a "butterface", and his girlfriend Jenny wouldn't let him swap with me. Like the teacher listened or cared.
Mike made sure to let me know about how much disdain he had, being a woman and all. Apparently I was "the worst possible swap classmate", although there was already two reports that year of students who "disappeared" with their new bodies. He made sure to complain when I flirted with his girlfriend Jenny. He made sure to scream at me after Jenny dumped him after I spent a night with her, using Mike's body to the fullest. He definitely made sure to moan when I pushed him against the wall, using my new football player muscles to hold him down and take his cherry. After that, Mike gave up. He was putty in my hands, free to use however I wanted.
That was two years ago now. Somehow the swap machine broke, right before Mike and I were supposed to go through it. And our school couldn't afford to replace it. So we signed some waivers, one of us more eagerly than the other, desperate to please me. And now, here we are. Mike's nothing more than a little slut for me, my source of entertainment whenever my wife Jenny isn't around...
