Slowly Swapping: Chapter 3 - After Class

Jon took a breath as gym class ended, somehow he'd managed to keep anyone from noticing his panties. All he had to do was change back into his clothes and the rest of the day should be a cakewalk. Jon passed the other guys in class already taking off their gym clothes as Jon got to his locker. He put in the combo, it flipped open, and Jon took his clothes out in a pile, but something caught his eye. A pink strap, which when Jon investigated was connected to a pink bra, the same color and style and the panties he was wearing, it had to be connected. Jon paused... he was in the middle of the locker room, some of the guys were looking at him, he couldn't very well hide it now, So Jon tried to play it off. "Is someone playing a prank on me or something? I found this in my locker." Next to him an acquaintance of his, Tim Spoke up.
