You keep shitting up a storm, forcing out another pile of manure onto the dirty carpet, both embarrassed and completely aroused by the new sensation of each greasy, rank pile forcing its way out of your asshole, it's almost euphoric. You look down at your massive pile, feeling the warm shit squish against your feet as you step in it, it's impressive really. You keep staring at it, it slowly becoming less disgusting, and more...appealing. You feel yourself begin to drool, the horse man giggling as you become more and more fixated with scat pile.
"Just one bite," you tell yourself, trying to justify this venture, as you crouch down on all fours and take a massive chunck of greasy brown shit out from the pile with your mouth. Your eyes water begin to water from the overpowering, sour and meaty taste, but you have no problem swallowing it. The horse man continues to laugh, but you don't even notice, going in for another bite, a much larger bite than before, thanks to the snout you also failed to notice growing from your face. You keep savoring each bite and the scent of the rotten manure with your rapidly heightening senses as you continue to wolf down your own excrement, only stopping to raise your tail, hunch over and push out more savory, steaming, green piles to enjoy. You keep continuing as you feel your furry belly begin to fill completely, distended by the sheer amount of scat, you've ingested. You stand back up on your feet and turn to your friend,
"Good going bud," the horse man says. "Now you have a costume, and I have a new roommate." Confused you tilt your head, sucking the shit from beneath your claws. He just laughs and points to the nearby mirror. You walk up to it and staring back is an anthro german shepherd. You accept it immediately, admiring your toned abs, with 8 nipples, your shit-covered fur, your new muscles, your tail wags with glee. You begin to strain again, lifting your tail and drop the biggest load of sticky, wet shit, you've had so far. You go down for it, tantalized by the scat, and start rolling around in it, spraying loads of cum all around the room as you cover your furry body in your warm, wet stink. You soon finish, electing to lick it off your body afterwards, going into every crevasse and every cresse with your canine tongue. You glance up to see your friend, completely naked, allowing you to admire his muscular horse body, covered in his dark brown fur, his exposed, erect cock is even longer than yours dripping with copious amounts of precum. He presents you with his pair of overalls, still shit filled. You gladly accept them, sliding them over your loincloth, feeling the warm squish of his horse manure against your pelvis, your cock becoming rock hard as his horse shit cloaks it. You go for it, grabbing a handful of his manure, shoving it into your canine snout. It's a bit more nutty than your own, but it's even more delicious. You get down on your knees and beg for more, closing your eyes and opening your mouth, but instead of the shit you had wanted, you get his salty wet horse cock in your mouth, not what you wanted but it's now something you needed. You have no trouble rubbing your tounge along the tip, stimulating it, forcing him to let out a loud neigh of pleasure as he pumps his sticky fluid into your mouth as you gladly lap it up. Days pass and the two of you become more, intimant and even more disgusting, soon you forget about your human life, resigning yourself to a life of an Anthro German Shepherd, obsessed with eating his own shit, and his stallion boyfriend.
