Noticing a rather interesting folded up latex suit hanging from the rack in the back you ask the guy at the register about that one.
"What One?" He says looking at what you were pointing at. "Oh that old thing? Used to be the store mascot before it became defective."
"Defective? How?" You asked.
"It popped. So we made it a full body rubber costume. last guy who wanted to be that thing did it permanently, so no renting that one because if you put it on you wont be able to ever take it off. But no one wanted to buy a used rubber costume without a dick, it so i stuffed it back there after awhile not really knowing what to do with it."
"It doesn't have a dick?"
"Yeah, last guy ended up popping it, i repaired it by removing the dick and welding some rubber shorts onto it. Then I put some magic into it so it wont pop again. It comes with a strap on that functions as a detachable dick and the anus is still usable since the underwear had a anal condom. So there's that. If you want it its free. been trying to sell it for months."
"I can seriously have it for free?"
"Yeah but you got to put it on here in the store. So do you want it or not?"
"Yeah sure i'll take it. Sounds sexy."
"I'll wait outside the secret room, knock twice when your done." The man said as he stepped out and closed the door.
You walk over to the costume and realize why it seemed incredibly folded up, its not just a single rubber suit, but a full blown incubus costume, with wings, horns, tail, claws, spikes on its back, elongated pointed ears and everything, even has a few heavy rubber bracers with spikes on it around its arms with loops on them, possibly for tie-downs and some rubber spiked shin-guards that also have the same loops for tie-downs. It has claw-like fingernails on its hands and feet, and some rubber vampire fangs in its mouth. Its horns bend backwards in a perfect arc all the way around to the back of its head and its hair is made of many strands of rubber that flow to slightly above its ankles. The hair is of strands of red and black, the underwear on it is black with no seams and a red waist-band and leg bands, its eyes are solid black rubber, as are its claws, wings, back-spines and tail, its skin is a pure pearly white.
Looking over your costume, you can see its going to be a really tight fit, as this thing has a really effeminate twink-boy build to it, but hey, a free rubber demon costume for a gay guy isn't worth passing up. You undo the zipper in its back and glide one foot in then the other, you pull its legs up yours and are surprised on how stretchy it is. You then pop your arms into its arms and then struggle to get its head and face over yours, you finish situating it on you as best as possible but then here a zipping sound as it seals you in on its own and feel something bizarre happening to you as you begin to feel lighter and the zipper disappear completely, something feels like its poking out of your lower back right above your butt.
"What the hell?" you say as your voice starts to raise in pitch, quickly turning to something that sounds like its made of latex rubber. You get your hand around to feel what it is growing in you and check your back. the zipper is completely gone and you feel what it is poking out of you. You nearly fall over in orgasm as you touch what must be an air-valve. You cry out in pleasure but your voice is fading into rubbery creaks and moans as the suit changes you. You feel your body morphing into its shape it was intended. Everything tingles and is becoming more sensational as you can feel the suits extremities becoming your own, you can feel its wings as if they were yours as well as its hair and horns, spikes and tail. everything is becoming more and more sensitive on you, both inside and out as your inner body is quickly turning into air.
Your tail is incredibly sensitive, like touching your dick when its fully erect, but twice as good, you fall over backwards onto the rack and try to catch yourself as you turn into a balloon of an incubus, and can feel that something inside of your ass feels solid, and something in your groin feels missing, you then remember it doesn't have a dick, but you can feel like your fucking your own ass right now, huffing with rubbery creaks and moans, you put your hand in your asshole to find out whats in there and pull out a massive 12 inch black rubber dildo with your claws. Your claws are surprisingly tough, being made of rubber, but you nimbly pull the dildo out of you, it pops out with a loud plop! and you feel like you pulled your dick out of your ass and are holding it in your hand.
You then try to get a good look at your new dick and can see theirs a suction cup or something on the base of it, and you instinctively stick it to your crotch and it sucks onto you with a thwomp, you instantly feel like you have an erection and are ready to start spurting. You are becoming sexually stimulating to the touch anywhere, even your hair feels stimulating rubbing against everything around you. Your inner body is almost gone and you feel your heartbeat stop as your chest cavity turns into air. Your vision then starts to change as does your sense of smell and hearing, your ears become more attuned to their surroundings and can hear the rubbery squeaks of your own body as well very sharply. Your eyes seem to dim a bit from the black latex but are also working better in the low light, the vision then starts to come back as you realize you can see in the dark and in full color. your nose is also becoming more attuned to the smells around you, and your own latex body. you then can feel your mouth open as the fangs, rubber tongue and mouth of the incubus costume pushes into your mouth and locks into place, your throat goes back about maybe 6 inches into your torso, but strangely it feels like your asshole and throat are trying to connect in a long rubber tube, you feel them connect together and try to talk, your vocals are gone and only rubber moans and squeaks come out as you try to talk.
~great, i cant speak anymore now. that's great...~ you think to yourself as your brain and the last remnants of your human body turn into air and rubber. You feel yourself complete the transformation and a great lust in you to go out and find a human to fuck fills your mind, you give a good sniff and can smell things you couldn't before, you can smell the old guy in the other room, and strangely can kind of see a weird aura about him you couldn't before, its a deep crimson red and it calls you over to it. You hone your new senses and realize you can smell and see his lust. You then grab your dick and pull and it pops off with retaliative ease, and without thinking stuff it back into your own ass. Your rubber vocals moan in enjoyment with your dick back in its storage compartment to carry it until when your ready for sex.
You then try to take your first steps in your new body and find its incredibly nimble and strong for being a big balloon, even with its dainty form. You walk over to the door, rubber squeaks coming from your body as you walk. You get to the door and knock and the cashier opens it up and gives you a once over.
"Well rubber boy, looks like you did take the costume after all. its yours now, or i should say, its you."
~yeah but i can't talk anymore asshole~ you grumble in your mind.
"No shit, you don't have any vocal cords anymore, but others can hear your thoughts. so try to think nice sexy thoughts when looking at people unless you want to have them hear you calling them an asshole."
You stopped for a moment surprised he could even hear what you were thinking. You then have a feeling that the man your looking at is getting aroused by your form, you can smell his hormones and its making you hungry. You don't even notice yourself starting to sweat rubber polish from your skin as you lust for sex.
"Get used to being this b/c its permanent right after I deflate you."
~What!~ you scream in your head as he grabs your valve and unplugs you! ~No!~ you say as your strength quickly starts fading from your body and you deflate, falling unconscious on the floor.
When you wake up...
