You look at Mike and say "what do you mean turn into shoes?" Mike replies and says "it really is as simple as it sounds. If you cum in the back room, you'll turn into a pair of shoes for people to be able to wear and transform into you. You'll be aware you're shoes, and you'll feel their feet inside of you. You'll also feel them and see them turn into you." You're first instinct is to run, but something is keeping you in there. You don't really believe Mike it's possible to turn into shoes anyway, so what do you have to lose? I mean, since you already have a hardon anyway, you might as well jerk off since you have the chance. You look at Mike and say "how long do these effects last." He says they're permanent until your wearer turns into a pair of shoes. You'll become shoes on my shelf forever until then." You still think he's bluffing, and you really want to jerk off, so you decide to go into "the room" without any shoes or socks. You just really need to jerk off.
Mike closes the door, and you pull off your clothes. Looking down at your body, you're really proud of yourself for spending years at the gym. You're not really a gym rat per se, but you do have a nice body with good biceps, abs, and pecs to kill for. Your shorter spike styled blond hair just accentuates it all. It feels good to take your clothes off and grab your dick. You begin to jerk off, and you feel it's almost extra sensitive today. It doesn't take you long to reach the point of no return. You begin to feel the surges of pleasure come to the base of your dick, and then it happens. You begin to cum, moaning deep in the pleasure of it all. It feels soooo good to be cumming in this room. But you notice the cum doesn't stop. You continue the glorious orgasm, long after it should've ended. Your moans continue as you look at your arms. They're starting to get thinner and longer! Your hands and fingers are disappearing, forming an aglet on the end of each of your arms instead of hands. Your legs are doing the same thing. They're becoming laces! Your orgasm is continuing and more cum is spurting out as your body turns into a think fabric. Your mouth begins to widen, and begins to take over your whole head. Your tongue forms into a shoe tongue, and sticks straight out from your chest into your mouth. You feel your chest begin to turn into shoe fabric as your arm starts wrapping itself all through your chest. Your chest and head is a left shoe! Your bottom half is starting to do the same, with your butt becoming the whole for this shoe. Your thighs are starting to become the shoe itself, and you feel your legs begin to wrap through and around your thighs and butt. Your penis is still untransformed, continuing to spurt out large amounts of cum. It then begins to turn into the tongue for the right shoe that is your lower half, spurting out the last of your human seed. You are now a pair of shoes. An object. And since you didn't wear a pair into the room, you didn't change anyone back into a human. Mike comes in and picks you up, and puts you on a shelf with the label "muscular stud gym shoes."
