half way through first period, Jon felt like doing something, to start the day, he slowly bent his body's bra hooks, until they came loose and were unable to be rehooked
Sarah felt it and excused herself to the bathroom, thinking that she must have just missed a hook and it came loose or something.
in the bathroom,
"damnit, I can't go around with my bra loose and i can't go without in a tanktop. oh I've got a sports bra in my gym locker i could use for today"
Sarah quickly made her way to the gym proud of her quick thinking.
jon hadn't thought of this and needed to think of a way to stay as her entire wardrobe.
she made her way to her locker, and opened it revealing her gym clothes and sports bra, she took the sports bra and laid it on the bench in front of the locker.
she started taking off her shirt, and Jon saw his opening, he made a copy of the sports bra in the short time he had.
using the his body/sports bra, he slid the real one under the bench and a few feet away.
Sarah, unaware of the switch removed her Jonbra and replaced it with her Jonsportsbra.
She relocked her locker and hurried back to class, Jon purposely shifted up and down, causing her to bounce, much to her discomfort.
