The muscular tiger grunts in compliance and tells you: “Bring a costume, don’t worry about paying.” You follow him to the back of the emptying store; it was 11:00 at this point. He leads you to a door which, according to the tiger, leads to the dorm rooms of the mascots. You wonder why the party would be held at the dorms, completely ignoring the fact that this zoo has dorms anyway. He walks you to a well lit bedroom. You see another man, this one led by another tiger, approach as well. You realize that you had seen that man in the tiger section of the store just earlier. You are both left in the bedroom, holding tiger costumes, while the two Tigers leave.
You notice the very strong smell of a man’s sweaty musk in the room, and immediately think it’s the other man with you, but wanting to be polite you ignore it.
“So you like tigers too?” You ask him. His body was similar in build to yours, pretty athletic and moderately muscular. You could clearly tell he lifted weights as much as you did and found yourself staring at his muscular chest under his tank top.
“Yeah.” You see him glance at your crotch a few times. “You got a big dick?” he asks, then clearly hides a look of shock and embarrassment. He thinks to himself, “Why did I say that? I’m not even gay.”
You begin to notice something is off. You aren’t gay, yet you can feel yourself become attracted to the man you’re speaking to; you don’t even know his name. Your thoughts are invaded by an image of his uncovered muscular chest, his stubbly face in a sly smile, asking you for a kiss.
You suddenly see him take off his tank top, revealing his muscles, as he discreetly flexes at you. “Is it just me or did someone turn up the temperature?” he says.
“Yeah...” you reply, following suit and taking a step closer to him.
You look down lovingly at his crotch, mesmerized by his body. He takes off his shorts, revealing his boxers, and grabs his costume.
“Maybe these costumes can keep us cool...”
You reach down to pull down your shorts as well, only you pull down your boxers as well, revealing your cock. “Oops!” you say playfully. “I guess we won’t need those anyway.”
He smiles coyly, taking off his boxers as well.
“You’d be pretty hot as a tiger...” you tell him.
“You too.” he replies.
You see him pull the zipper down on the back of his tiger costume, it reaching to his 6’4” muscular frame. You, wanting to help, guide his legs into the tiger costume. You see him wiggle his toes through the paws of the tiger costume, testing his mobility.
“I need help. Can you push that thing in the back into my ass?”
You gladly oblige. Seeing the dildo in the costume, you slowly guide it into his asshole. He moans lightly, feeling every barb of the tigrine dildo penetrate his asshole, now held permanently due to the barbs. You get extremely horny seeing his cock fill the costume’s condom. The striped tail hangs perfectly from his ass and he continues, pressing the fur of the costume against his chest, his muscles outlined perfectly.
He puts his arms inside the costume’s sleeves as you lightly stroke his furry chest, almost done. He finally allows his mouth to take the dildo in the costume’s maw, as the barbs scrape his mouth. You zip the costume up and trap him in the tiger suit. The only thing about him that stays human is his eyes, with a small border of skin shown through the costume’s eyeholes.
“Make me a sexy tiger too...” you whisper into his ear, running you hand down his large bicep, the smell of manly musk now overwhelmingly attractive to you and your costumed partner. You slide your left leg into the costume, sitting on the bed, as the costumed “tiger” strokes your cock lightly. You slip your legs into your costume, and without even having to ask, he shoves the dildo into your asshole, making you grunt in slight pain as you feel it implant itself into you permanently. You stroke your own cock lightly through the costume’s condom, as you feel your “feline” companion pull the costume over your body. You stick your hands and arms into the costume’s, surprised at the dexterity you get in the padded hand paws of the tiger. You finally feel the other dildo enter your mouth as the “tiger” pushes the costume’s mask over your face and zips up your zipper.
You moan as the other costumed man, dominant, shoves his now hard cock into your face. You allow him to stick his cock into your dildoed mouth, still feeling his cock go deep into your throat. You use your tongue to cause him pleasure. He pushes you onto the bed and turns around so he can suck your cock as you suck his. You moan as his tongue massages your barbed, costumed cock, and feel his cum enter your still human mouth, spilling over your orange fur as well. He still strokes his own cock while you feel his muzzle pleasuring your cock, causing you to cum into his mouth, and you both swallow each other’s cum, too turned on to care.
He reaches behind you to finger your asshole through the dildo, penetrating your ass with his clawed paw as he sticks more fingers into your asshole. He fists your human asshole as you moan in pleasure, but this prepares you to take his nine inch cock. He releases his large fist and is able to force his cock into your muscular but loose ass. You grunt with every thrust until you feel his thrusts get faster. You moan, in pure bliss, until he spills his cum into your ass.
You feel the changes wash over you, as the tiger costume invades your body, powered by the cum of the man. Your muscles become much stronger despite not changing in size or mass. Your feet deform into the shape of a feline’s, as you feel the striped tail hanging from your ass gain feeling. Your skin tingles as your new fur settles into your pores. Finally, you feel the muzzle of the costume overtake your body as the dildo in your ass makes your tiger asshole loose permanently and as the suit’s penis takes over yours, taking it to ten inches in length.
You let out a growl, your cock dripping with precum, as you turn back to him. Your mouth now free to speak, you tell him, in a deeper voice, “You’re gonna take all ten inches of my cock. You’ll be a hot tiger.”
You pounce on him, his cum staining his fur, and shove your fist into his asshole, stretching it out considerably. You hear his muffles moans as you thrust into his ass, sending spikes of pleasure into his asshole with your furry, clawed fist. You remove your fist as your cock enters his asshole. He moans and strokes his cock as you thrust into him, as you grunt and pant loudly, your new nose picking up the scent of his sexy musk, until your cock shoots a gallon of cum into his ass, it also spilling out onto the floor and drenching your fur in your own sperm.
You feel his muscles ripple under him as his changes happen. His tail comes to life, standing erect rather than limp to the side. His cock grows to become bigger than yours. He stays at the same build and height, still 3’ taller than you, and he roars loudly as his face is transformed by the mask.
You stop pumping your cum into his asshole as he cums all over the both of you. You slow the stroking of your cock as he pants heavily, his rough tongue hanging out of his muzzle.
