You see a pelt of orange fur standing in front of you. The tall muscular fox costume looks at you with it’s hollow eyes, it’s fluffy tail
“You!” you freeze, hearing the costume speak, the long muzzle moving with it’s speech. “I’ve been trapped hear years alone. Fuck staying in this musty room. I’ll take you for a night you’ll never forget.”
You, scared shitless by the orange and white fabric behemoth, simply stutter out “W-what the f-fuck...” as it approaches you, it’s huge cock dangling from his furry crotch, deflated. It, in a fluid like motion, slithers on the ground towards you.
You flinch, feeling the costume jump into your shirt, opening up its seams and enveloping your torso in fur, white on your chest and stomach. “Oh fuck yeah, I’ll finally have a host,” you hear it say, as it forcefully shoves the dildo in the costume’s ass up in your asshole, keeping it expanded under your clothes, and sliding your cock into it’s bright red dildo. This all makes you moan in pleasure.
As the costume finishes wrapping your well built legs in its digitigrade legs and plasters its vulpine mask over your human face, it invades your mind with strong, foxy, instincts.
Must fuck... you think to yourself, the rational part of you still feeling inside the costume’s muzzle to see if you’ve actually transformed. The costume relishes in the fact that all it needs is cum in your ass to transform you permanently, and leads you too...
