Casually, you pee into the urinal in front of you. Bored, your eyes wander a bit. This wandering has your eyes lock onto a big body to your right. Caramel brown fur over bulging muscles all leading up to a pair of giant horns atop his head. His body is like a large tower of muscle, he's seven feet tall at least! You immediately pull your eyes away and awkwardly stare forward. Unfortunately, your peeking didn't go unnoticed as a pair of eyes burn holes in the side of your head. He starts in a deep baritone, "I see you don't have a costume; you've been eyeing me up, do you want mine?" At first, you think to ask if he's really in costume. It's very realistic. His chest rises and falls with his breath. His fur looks thick and plentiful, and no part of his body looks deflated. With seemingly no other way to get a high quality costume, you force out, "Sure,"
"Alright, follow me," You zip up your fly and follow him into a shop across the zoo path from the bathroom that has a changing room. You see his bovine legs as he walks. You also notice that he's wearing nothing but a long loincloth.
"Wait here," He enters a changing room after grabbing some jeans and a shirt and leaves you waiting right outside his room. You wait and listen as he changes. You hear him huff and grunt; such a realistic costume must be tough to get out of. Five minutes pass before the changing room's door opens again. Exiting it is a man of about six feet in height, with smaller yet still sizable muscles. His striking eyes meet yours and he hands you what looks like a pile of fur with a couple of horns as well as a loincloth. "Here you go, I'm not asking for anything in return," That same baritone voice says to you before walking off into the zoo crowd. You stand there with a decently heavy bull hide in your hands. This is going to look rediculous on you! That guy was muscular, but you're average at best! Maybe there'e padding? You hope there's padding. You take the man's gift with you into the dressing room and begin to strip down. You stop at your underwear and look for an entrance to the costume. In your search, you find a rather large prostrusion from the minotaur's crotch. "Oh wow, this thing has a dick?" You wonder aloud. It's a big on two. It's 2.5 inches thick and 10 inches long.
Eventually, you find an opening on the minotaur's back. A long slit down the back of the costume allows your feet to slip into the strange legs. Immediately, you notice that the penis is hollow, "So that's how he was peeing! But it's so big..." You decide to remove your underwear so that you don't have to get out of costume to take a leak. Placing your feet back into the sleek confines of the digitigrade legs -- toes falling into the hooves -- you feel cool and comfortable so far in the costume. Wanting to feel it more, you slip your dick into place and move your arms into the smooth arms of the costume. Despite being covered in fur, the costume is actually quite cool. However, you look down at your body in the costume and are disappointed. Rather than being large and in charge like the man from before, the costume hangs loosely over your lackluster frame. You frown and are about to take it off when you feel something strange in your legs. Looking at them, you feel the bones in your legs shift and watch as the swell up in the costume until it looks tight over them. You stand in awe of your new legs and go to feel them with your hands. The rough hands of the costume stroke your bovine legs, and you feel the hands as if the costume were your skin!
Suddenly, fear takes you. Is this thing turning you into a minotaur forever!? How can you go back to your job or your friends as a minotaur? They'll think you're a freak! You immediately scramble with your still costumed hands to pull off the costume from the waist. Your hands grope around your back for the slit, but find nothing! Craning your neck to see, a mirror shows that the slit has sealed up! Before you can think of another solution, a familiar swelling feeling takes your chest and arms. You feel your chest widen in the costume. Pecs grow until the bulge forth proudly. Hard abs grow into place, and your biceps ache until they're more than 6 inches thick. Your hands expand and fill out the rough hands of the costume. You are just about paralyzed with shock and pride. Look at you! You're a behemoth and you didn't even have to try!
The aching and swelling have stopped, leaving the costume stretched over your giant body. Also, did you get taller? The floor seems farther away after your massive growth spurt. This is actually nice. You feel so powerful! You squeeze one of your meaty biceps with one of your manly hands. It feels and looks like a melon! You feel like you could wrestle gorillas and win. Why don't we finish this up and lut the mask on? Wait. No! The costume's getting to you. You have to get this off! Maybe your new strengh could allow you to rip the costume off? You grab the opening at the head of the costume, and -- just before you pull -- you feel the swelling from before in your dick. Your knees almost buckle beneath you with pleasure. You moan quietly as you watch the formerly limp dick of the costume fill up with your meat. In your tantalising moment of lust and pleasure, your bull cock gets hard and strains against the costume as it stands at attention at a foot long. A shaking hand traces your buff torso to your cock, where you give a big squeeze. This time, your knees come out from
under you, and your big body slams heavily on the floor. A hot breath escapes your mouth and you feel your human balls fill with you bullish lust. They grow until they sag at the size of a baseball together on the floor. Another squeeze and you moan loudly, dripping precum on your hand. Your face is hot and sweaty and you decide aloud, "This... forever... so good..."
With that, you pull your hand away from your hard cock and pull the mask over your head and seal yourself in. You feel swelling in your nose and mouth ad they push out into a bovine muzzle. Your horns cling onto your head and lock into place right above your ears. You continue huffing and pull on your dick with both hands. You instantly release a deep moan in baritone just lower than the man who gave you this amazing gift. You also smell your hot breath. You feel blood course into your bulging muscles, the cool floor under you, you feel a bovine tail trace the floor from just above your toned ass, your hooves clop on the floor as you masturbate on the changing room floor. Chocolate brown fur covers your legs while your caramel hands tug on your bull cock. Your pulling and pumping get faster and faster until you reach a peak of heat, pleasure, and pressure in your dick. For the first time, you shoot a giant load of bull cum onto the wall and floor of the changing room. Loudly, you moo with sweet release.
You breathe heavily in and out, hot breaths until you cool down and your member returns to ten inches and soft. You lug you heavy body off of the floor and remember your clothes. Won't need those anymore, you just leave them on the bench. You then tie the loincloth around your waist and stretch. You feel the cool air conditioning on your hot body and you huff hot air out of your nose. You finally open the door and leave it a new person. You see the lady running the front of the store and apologise, "Sorry, made a bit of a mess back there," Your voice comes from deep in your throat, and you like the feeling. The lady gives you a knowing nod, and you leave the store, back to the zoo and the night.
