You wince as you feel another volley of shit and another spurt of cum fill your diaper simultaneously as you take your furry, hide-covered hands and cup more cum-soaked shit and coat your chest. The female horse attendant, who seems too turned on to think clearly, reaches inside your shitty diaper and coats your back in shit. You feel your muscles tense up as the manure turns your hair into hide and your muscles pop out more and gain some definition. You push out more shit and cum again as she starts to strip, not bothered by the shit staining her clothes as she reveals a diaper on her ass as well. She starts grinning at you as you fill the diaper more and more, it noticeably sagging now. She turns her ass to your face and says, “You’re gonna be my sexy stallion hunk, free of charge.” You hear a hiss and smell an even tangier shit smell come from the padded ass in front of you. You fall back and smash the shit in your diaper, it explodes from the leg holes and starts to transform your legs into that of a very muscular stallion. You watch her diaper bulge out as she lays shit into it, you even hear a hiss as it seems she is full on using it as a toilet in your face. You are completely overwhelmed with the smell of manure, the sound of shitting, and the feeling of pleasure from the entire experience. It was as if you were hypnotized, only enjoying the feeling of transformation as you were numb to the changes. You were didn’t even notice the diaper leaving your face and the mare standing back up. She peels the diaper from her ass and puts it in her hand. She then smirks and turns towards you, prepared to throw the shit-filled diaper into your face. You only register the words, “Eat up, dummy!” as you are immediate covered in wet manure and piss from her diaper. Because you were still entranced, some of it slipped into your mouth. Instead of reaching to pull it off and immediately gagging, you feel your face start to shift, greedily snorting the shit and licking it up as you cum even harder, your diaper barely holding the mess you’re making. Your whole body is now transformed into a massive, muscular horse anthro as her diaper slides off your face and your diaper falls to the ground in a loud, messy splat as you now stand 7 feet tall. You flex as your messy ass sputters a wet fart. The mare in front of you walks up to you and leans against you, loudly smelling your body. Despite the absolute filth you did to transform and the new fetish, you do look like an absolute stud, and she makes your new 2 foot girth rock hard. What do you do now?
