You keep examining all the packages of diapers, curious on what they're all doing lying in this decrepit old mansion as you hear the door open behind you. "You've made a big mistake, friend," you hear in a deep bestial voice. You turn around to see a tall muscular black anthro wolf, dressed in only a diaper staring down at you, of course the same scent of shit wafting from him. You try to run but he's far too quick, in an instant he's dragging you by the leg back into the door from earlier.
Inside is a huge empty room, almost a gymnasium in scope, filled with all sorts of other anthro animals, like a gorilla, a bear, a lion, among others, all dressed in diapers and all reeking of shit. "We were just like you once, normal people." The wolf tells you. "But we were so fascinated by furry culture, we wanted to do anything to make it a reality. So when a certain scientist gave us a way to experience it, of course we couldn't turn down his offer. So we formed this little club. The only downside is we can't really leave, and now neither can you." You try to to protest but the wolf man just covers your mouth with his giant paw," don't worry, just do as I say and i think you'll learn to like it here." You stare at hin with fearful eyes, awaiting his command.
