Suddenly, something else makes it way to your peripheral vision: A Gym bag. "Isn't that Mr.Mills gymbag?" You ask Brian. "I think so, why--" He stops midsentence before looking at you. "I wonder" You say mischievously, walking over to the gym bag. Brian stands at the doorway watching you.
You finally make it to the neon orange gymbag and unzip it slowly. The only thing you find inside is a grey shirt, grey sweatpants, and some grey tennis shoes. Along with some socks and a jockstrap. At least I know what his favorite color is you think grabbing the handles of the gymbag.
"Where are you going?" Brian asks as you walk to the bathroom. "I don't want to break mine/your clothes" you answer. You walk into a stall and began to take off your clothes. Once you're completely nude, you grab the magic socks and Mr.Mills sandals. "Here goes nothing" You say putting them on.
You don'the feel any different until you feel a strange tingle on your body. Dark hair begins sprouting on your scrawny arms, legs and chest. You feel your face, a Beard has begun forming. "You ok" Brian says from outside. "Yeah" you say in a much more deeper tone. A bit surprised you feel another gentle ripple spread throughout your body. The floor gets father away as you began growing to Mr.Mills full height (6ft 1). You begin your put on a few pounds as your body expands.
Your body begins to fatten up as a belly and two giant man boobs appear on your chest. Your thighs and butt begin to fatten up as well, pushing you in a way you never experienced. After a few more minutes, you'really exactly a copy of Mr.Mills.
You know there's a mirror in the boys bathroom but you don't want to expose yourself to Brian. Thinking quickly, you grab the jockstrap from the gymbag and put it on. You exit the stall and make your way to the mirror. You see Brian gasp as you make your way to the mirror. When you finally see your reflection, you gasp as the jockstrap falls off you.
You look like the exact copy of Mr.Mills, in fact your almost beginning to think like him. Shaking those thoughts, you see your new black hair and hairline. Your face also has a Beard, like you expected it to. The rest of your body is bloated with two drifting man boobs and a big belly all coated with a light amount of black hair. You watch in shock as you noticed your/Mr.Mills dicky. Black curly pubes and a thick cock appear on your waistline. Finally you legs and thighs are just as hairy and thick.

You look behind to see Brian staring you up and down. "This is so weird...seeing my naked gym teacher in front of me" He says. Suddenly you remember the jockstrap falling down and feel your face growing red. "Well, I guess I should change back" You say in your new deep voice. "Wait, Mr.Mills, I mean Adam, how about I get a turn first."
You already begin to feel Mr.Mills memories inside your head and want to change back in case your caught. But you feel that you at least owe Brian a turn.
