You spot something strange on the menu, "The Smellinator Challenge" four huge full pound mystery meat cheeseburgers, topped with bacon, chili and mayo, eat it all and you get a prize. Your hungry and feeling bizarrely confident, you'll do it. "One Smellinator," you tell the vendor. He laughs, "feeling brave huh?" He goes back to prepare your food. "Here ya go," he says plopping the plate in front of you, "eat up." You gasp at the challenge you got yourself into. The four huge extreamly greasy meat patties absolutley drencheched in a ton of mayo and chilli. "No silverware or napkins either," he says.
Unable to back down from your challenge you pick up each meat patty individually with your bare hamds, chowing down, getting your hands, face and clothes covered in food. It tastes really good though, you don't know what meat it is, definitley not beef, but you love it. You keep eating, after the second patty you start feeling full but you keep going, you don't want to lose.
You keep persisting until the final bite, feeling absolutley stuffed. "I did it!" You say to the vendor. "What's my prize... " you pause feeling ill. "Actually where's the restroom?" Don't worry Stinky, there's a private one in the back." You ignore the name and go around to the back of the booth and go in the bathroom. You feel really sick, and bloated, very bloated actually. You glance into the mirror and your filthy food covered tank top is looking more like a bra on you, your pants ripped apart from the button and the ass ,you're suddenly extreamly fat.
You feel your belly rumble and let out a loud fart, spraying something warm into your jeans. Did you just shit yourself? Worried, you let your pants fall to your ankles, thankfully you didn't shit yourself but what you find is much worse, thick black fur covering your legs, spreading up your body. As it goes up a large tail erupts out just above your ass. The fur keeps spreading, covering your massive belly and flabby arms soon reaching your face as you watch in the mirror as it molds into its new form. Suddenly it all clicks together, the name Smellinator, the nickname the vendor gave you it makes sense know. The meat in the burger was skunk meat. You know because you're an incredibly obese dirty amthro skunk.
