Jim felt a little bad knowing that his shoes were once a person. But he didn't know that you enjoyed it, and would have for at least a while longer.
"Mike, is it possible to change my shoes back into a person?"
"Well, yeah, you go back into the room here, jerk off and you'll regress into your old self and then into a pair of shoes. There can only be one of any person so you change that guy back, and so do you. You can always try something else on, but you'll be in the same pickle don't ya think?"
Jim knew Mike was right; and this new body, your body, was too good to pass up. But the question had got Mike thinking because it wasn't one he'd been asked before. A smile creeped across his handsome face.
"Actually... What if we just turned him back, but into your old body?" Mike proposed with a chuckle.
You wanted to scream "No!", the thought of being that nerdy wimp was terrible. But Jim selfishly thought he might be doing the right thing for you, unaware that Mike was toying with you.
"Okay! How do we do it?"
"Easy. I'm gonna need those shoes and your old ones, old socks too. So you'll have to leave here barefoot."
"Deal."
You tried to make it clear you didn't want this, but there was nothing you could do as an inanimate object. Jim handed you over, along with his old shoes and ruined socks and followed Mike into the back room.
"Whoa, I feel so... horny in here..." Jim said.
"Yeah it's a special place," Mike replied, "Get off in here and before you know it you'll be a pair of shoes. If you wanna keep that hot, perky body o' yours you shouldn't stay long. Unless you wanna be my next pair."
Mike's sleazy but handsome grin was a sign for Jim that he should go. He nodded at Mike and backed out. The door chimed as Jim left the store. You screamed internally. There was no way you were going to track down your old body now. Mike placed you and Jim's old shoes next to each other and placed his big hands over both. Everything went blurry for a moment and suddenly you found yourself in Jim's shoes.
"Well, what do you know, it worked," Mike laughed, "Now, time to change back, slick."
Mike clicked his fingers and pleasure took over you. Your sneaker form spread out and unraveled. The rubber sole became fleshy as you felt arms and legs return to you. The end of the shoe became your head and soon you heard your own moans once more. But they weren't "yours". They were higher than yours were, just like Jim's had. Before you knew it, you were human once more on the floor in a sweaty mound.
Mike slapped his knee and laughed, pointing you toward a mirror, "Lookin' a little different there."
You shuddered at the sight of Jim's naked, nerdy body looking at back at you. You were once a lean, muscled 6'1" man who hit the gym regularly. Now you looked at yourself: thin, pale, about 5'9". This was a body that had never set foot in a gym. Your golden blond hair was replaced with Jim's scrappy, untidy brown hair and underneath you had his plain, definitionless face. Jim's eyes were blue like yours had been, but that was the only similarity to your old body. Mike opened a few cabinets and drawers and threw you some small clothing that fit you perfectly.
"Why did you do this?" you sighed.
"Hey now, it aint so bad. Ya wanna go back to being shoes, be my guest."
"Who's going to want wear 'weak nerd shoes' or whatever?!"
"You might be surprised," Mike laughed, "I don't think that guy was ever going to give up that body of yours anyway; so look man you can always take your pick of other stuff in my store too. Remember, all those shoes grant different bodies. The socks usually only change your feet, but can have some unpredictable outcomes; some guys actually end up as socks. Or, ya know, we can just have a little fun."
Mike winked at you. You were still repulsed by his manner. But his blond, masculine good looks and thick southern drawl had a strong effect, as did the huge, oddly hypnotic size thirteen feet he had. Mike was right though that you did have options. You turned your thoughts to the other items in the store, and then back to Mike. The sexual pressure of the strange room made the choices even harder to make, but you managed to make a decision.
