You grin as you feel the satisfying squish of shit against your ass as you press down on the diaper, forcing out more scat onto your hairy legs and the wooden floor of the dressing room. Stench filling your nose, only seems to bring a smile to your face instead of the disgust you had imagined, why not add onto it? This is only teenage human shit, imagine what else it could be, bear shit, werewolf shit, a mountain of shit sticking to a new hairy lumberjack body. You feel your cock press up against the brief imagining the possibilities. Quickly you slide off the brown stained diaper, letting it fall onto the slop on the floor. You feel your asshole constrict to its original size, stopping the flow of warm, brown, poop out of your ass. Quickly you toss on your pants and rush over to the costume rack, hoping not to be questioned about the stench hanging over the whole store. You move fast but you find the perfect one.
