"Matt- I mean, Katelyn... Would you please come to the front of the class and answer this question.” Miss Moretti asked, pointing to a math equation on the chalkboard. From the back of class Katelyn grinned, pulling out her chair and getting to her feet. As she walked between their desks the eyes of every student rested on her body: her huge breasts, barely contained by her uniform, bounced with every step and her tight ass swayed along with her short skirt. Ever since Matt had changed bodies with school cheerleader and curvy heartthrob Katelyn, attention had been all on her.

Enjoying the attention, she pretended to drop the chalk on the floor. “Oops, sorry...” she cooed, bending over and showing off her booty (and a peek of her panties) as she took her time picking it up again. Finally leaning into the board, as she tried to solve the equation her large breasts began rubbing against the chalkboard which smudged teacher’s notes. Seeing that Miss Moretti was beginning to get mad, she decided to take it one step further - hiking up her skirt, she fully exposed her round ass and cute white panties to the class to a collective gasp. “Enjoy the view, everyone! Check out my cute little butt!”

“Matthew!” scolded Miss Moretti, trying (and failing) to obscure the view with her body. “To the principal’s office, now!”

“Sure thing, Miss.” Katelyn replied, turning around and adjusting her bra, letting her big boobs shake on her chest. Leaving the classroom she took a seat outside of the front desk and began playing with her boobs again to pass the time, wiggling them around whenever a group of boys walked past to watch them get embarassed.

A few minutes later the Principal left his office, and instantly his eyes rested on Matt’s sexy body. “Matthew... Not again. I know you’re a usually a troublemaker, but I warned you last time that you can’t exploit Katelyn’s body when you’re in swap class. This time it looks like I might finally have to expel you from the school...”

“Oh noooo...” Katelyn cried, feigning distress. “It’s just, getting used to Katelyn’s body is just so difficult... Especially when I have big, sexy breasts like these...” she pushed out her chest as if her giant H-cups, already colossal on the tiny teenager’s chest, needed any more emphasis. “If only there was something I could do... I would do anything to make sure you keep me here...”

“Hmm... I suppose we could come to an arrangement.” the principal replied. “Here, let’s come into my office to discuss our next steps.” As she turned her back, Katelyn reached into her pocket and turned on the microphone. If all went well, in a few minutes she’d be bent over the desk getting erotically spanked by the head of the school and then she’d have some prime blackmail material to guarantee she’d graduate with good grades. She was glad she’d secretly edited the records so she and Katelyn, the school’s bustiest and hottest student, were paired up for Swap Class, and not just for all the attention she was getting now. She loved playing with her sexy body every night in bed, squeezing her boobs and taking photos for her friends. Even better, she was sure she’d be to convince her new secret 'lover' to sabotage the Swap machine and make it permanent - and she was sure Katelyn (now Matt) wouldn’t mind. After all, rumors were going around that he was using his new body for ‘restricted’ purposes too and was caught getting a blowjob from one of his old friends in the cheerleading team behind the stands. Her mouth watering as she entered the principal’s office, she wondered about what it would feel like to suck off her former body too...
