You wander the store, not quite sure what you wanted. You looed to your left, deciding you didn't really want a bright pink elephant costume or a yellow hyena. You turned right while walking, coming across a section full of a rainbow of dragon costumes, deciding to examine them. You walk past all of the busty female costumes and over to the male costumes.
You pick up one costume. The design was of a furry blue Japanese dragon with a white underbelly, almost looking like some sort of anime character. You hold it out in front of you to examine it. The costume has well toned muscles, to the point of seeming like it would easily be skin tight over your large abs and thick biceps. You reach out to stroke the costume's furry pecs, feeling a strangely flexible yet rough and rugged fur fabric. The fur feels like it was skinned straight from a wolf or fox, and the 1 inch navy blue claws on the hands and digitigrade feet felt just like your own fingernails, just bigger and sharper, as well as the white horns sticking out from the head just above the dragon's ears.
You think about how fun it would be to fuck around in a cool dragon costume. Maybe you could even meet up with some other costumed people and party hard. You, with the costume bundled into your arms, go to the front of the store to find an employee. You see a woman in a realistic giraffe costume standing behind the registers. You ask her for directions to the changing rooms, and she points them out on the other side of the store, 80 m away. You thank her and start walking there.
You shut the door behind you and plop the bundle of blue and white fur onto the seat of the dressing room. You fumble around the costume's back and end up finding a well hidden zipper running from the costume's neck to its huge draconic tail. You open it up, seeing a smooth, warm, flexible material, and notice something you didn't before. There was a slit in the costume's crotch, presumably to have sex through, and there was a hole in the ass of the costume, leading to the outside of the costume just under the huge tail. "At least I won't have to take it off to shit." You also notice the smell of musk emanating from the costume, particularly in the crotch and armpit areas. You, deciding you don't care and still want to use the costume, strip to your boxers and try to put it on, but it gets caught and you can't get it past your waist. You were in fact unbothered by the musky smell, chalking it up to your own body odor, so you saw little problem in simply putting it on nude. Your boxers are thrown aside as you admire your naked body in the mirror, stroking your cock briefly, absentmindedly. You slip your leg into the costume, wiggling your toes in the foot of the dragon, and then slip your other leg into the costume. Your cock, being soft, doesn't poke out of the costume's crotch slit as you pull the costume up to your waist. You slip your arms easily into the costume's arms, and admire how well the costume outlines your biceps, in the mirror. You bring the head of the dragon costume and set it on your head. The head of the costume is tight and was clearly made to tightly encase a human head, with every movement of your head being almost perfectly mirrored by the costume. You reached around to your back and pulled the zipper shut, surprised at the dexterity and flexibility in the costume.
You take a moment to admire the costume in the mirror. The furry fabric of the costume hugged your body tightly, but was thin, showing your muscular contour under the costume. You moved and stretched, and the costume's fabric moved in exactly the way you'd expect skin to move. You opened and closed your mouth and the dragon's jaw did as well. Examining your face in the mirror, the eye holes hugged your face for maximum visibility and the holes were so small that only 1 mm of your skin was visible in the eyeholes. The horns of the costume rested comfortably on your head and came out at a very natural angle. The crotch of the costume showed a noticeable bulge where your cock sat.
Satisfied with the way the costume accentuated your muscular body, you realized you didn't want to go out with nothing but a flap of fabric between your dick and the open air. You put on your boxers over the costume, as the costume was so thin your clothes still fit, and then your shorts and shirt as well, choosing to ignore any footwear as that would no longer be necessary on the costume's draconic feet.
You approached the giraffe girl again.
"How much for this costume?"
She looks up from her phone. "All costumes are $49.98"
You take your wallet out of your pocket and take out your card
You, now much more confident in your new skin, waltz out of the shop and look for shit to do. There were many groups of costumed people around, maybe one of them would show you?
