Luper thought he heard a noise coming from the supply closet in the back room. His wolf ears clearly heard someone climaxing only 30 feet from him. He, on his padded hind legs, investigated. He walked over to the supply closet, his silvery grey fur smoothe and soft under his clothes.
You quietly whispered “Shit, shit, shit, what do I do” as you put your clothes over your suited body, somehow still fitting perfectly. Silently, Luper opens the door at that moment, straight after you put your clothes back on, and says “Who goes there?” You see the silhouette of a wolf much taller and more muscular than even your 6’2, 200 lb, wolf-suited body. Luper spots you in a short moment and takes your by the arm. “You know you’re not supposed to be...” he trails off, noticing you don’t smell like a wolf. He notes the smell of your human cum, and smiles. “Oh...” he says suggestively. “I see how it is... human. Zoo policy says you wear it you buy it.” You stand up and try to run past the wolf but he grabs you in his muscular grip. “Oh I don’t think so. You’re going to pay the price of trying to steal a costume.” You desperately try to reach behind you for the seam to take it off, and he says: “Don’t even try. That adhesive you used was permanent.”
He aggressively pulls down your pants and begins sucking your erect 6” cock. You stop resisting and moan in pleasure. Luper has ben trained to do this to thieves because of the increased costume libido. You feel his mouth leave your cock and come to your mouth. Letting Luper’s body-builder-like 6’8” form dominate you, he aggressively sticks his tongue into your mouth, far enough for you to feel it in your throat past the dildo. He pulls out and gracefully takes his green t-shirt off, exposing his ripped physique. Through the nostrils of the suit, you now became even more aroused at the smell of Luper’s lupine musk. He threw his shorts and boxers off, revealing his huge cock. With you lying on the ground, he stuck his 8 inch cock into your throat. It, covered in precum, slid effortlessly into the pink oral dildo and into your mouth. He let out a pleased grunt as he came inside your throat, you being forced to swallow his cum. You moaned in pleasure under the mask and his smell got even stronger. He now knew he had to finish again into your ass to transform you. He started stroking your cock first. “Oh fuck yeah..” you whisper. He’ll make a great boyfriend someday, he thought to himself. Overcome with passion, he is surprised as you momentarily gain control and fuck him in his ass. He, the only other gay wolf at the zoo, lets you fuck him. “Fuck, so tight..” you say. “Oh shit.....” he moans. You feel the effects of your raised libido and thrust harder and harder into his loosening asshole. You finally feel your climax and cum into his ass. Luper must now finish his mission and stops letting you have control. “It’s time, big boy.” He sticks two of his fingers and sticks them into the dildo in your ass. You begin stroking your still hard cock as Luper thrusts his strong fingers harder into your ass. He pulls out his fingers and, holding your shoulders, sticks his red cock into your ass, reaching just past the dildo in your ass. “Oh fuck... keep going” you say as he fucks you in the ass, pulling your fluffy tail up to have access to your toned ass. You feel his hard cock fuck you harder and harder until he releases his warm cum into your ass. You feel the cum left in your throat and ass tingle and quickly spread into your body. You gain 6 inches in height as the black wolf you are falling in love with cums in you. You feel your spine extend and take control of your new tail. Your face expands into the muzzle of the mask and you feel your mouth open up and your tongue grow, now outside of your new muzzle as you pant from the heat. The fur on your body creates pinpricks in your skin as it becomes a part of your new frame. As you grow taller, you also gain many pounds in muscle. You can now much more clearly smell Luper with your new nose. As the last of Luper’s cum enters your asshole, you howl in pleasure. Luper looks over you, satisfied with his new boyfriend. You look at him in dazed happiness, then shock. You are now a wolf. “What the fuck just... happened?” You say out loud, to no one in particular.
“You’re my boyfriend now” Luper replies.
