He reaches into his bag and pulls out a leather collar. "Here, this is for you." he says as he fastens it around your neck. "No thanks, I don't want any more of your freaky shit. I'd actually prefer if you leave." you say, reaching for the collar. You try to pull it off, but it seems to tighten under your grip. "Why won't it come off!?" you worriedly shout at him. "Oh, you see, I work on a farm, this isn't some ordinary collar." he chuckles. He pulls out a thick rope and fastens it to the collar and the other end around the support beam of the room. You sit down on the floor as that's your only option and suddenly start to get itchy. All your body hair starts to thicken and turn white, slowly becoming almost fur-like. "What's going on!?!" you shout, your voice cracking. White fur starts to cover your skin, spreading up your chest. Your fingers turn brown, your index and middle fingers start to fuse as well as your ring and pinky fingers. The fused fingers start to swell and harden, turning into hooves. It all suddenly stops, you hope that it's over, but then suddenly your feet start to hurt and feel tight in your socks. Your feet rip through the socks, now hooves as well. "Stop! please!" you shout, but Aaron looks at you blankly. The fur spreads to your groin, your cock straining against your shorts. Your cock starts to grow again; 12, 14, 16, 18, 20 inches with balls the size of mini watermelons. Your cock darkens to black and your cock head begins to shift shape, flaring out. You look at your cock, now that of a large stallion, in a mix of fear and lust. The fur begins to spread again, reaching your face. Your mouth and nose begin to blacken and your lips swell. Your nose flattens and your nostrils widen as your face gets hot. Your face begins to push outwards and you can see it in your field of vision; a horse muzzle. Your ears shift back, your pupils become rectangular, and your teeth grow larger. You look in the mirror to see a horse/human hybrid staring back at you, you want to scream but it comes out as a whiny. A searing pain runs down your spine as your ass swells, your bones shift and your tail pushed out. You are now a snow white stallion.
