You groan as a small sprout bursts from just above your stinky butt, slipping through a small hole that you never noticed in the back of your beast briefs, and growing out with a tuft of fur at the end of it. Hair surges across your body, covering you in a thick coat of warm fur, as well as an extra load of fluff appearing around your neck and atop your head. Your skull cracks forward, painfully for only a moment, before settling warmly again and feeling much more comforting. Your body grows and you can't stop stroking your cock, loving the extra girth in your meat, the cum surging into your sack as it bloats up full of more and more cum, and your muscles explode all over until you're just as big and hulking as the rottweiler.
As you stand there, tail lifted and ready to fill up your diaper with your first load of stinky lion turds, you lock eyes with the rottie. His eyes are twinkling and the drool coating his lower jaw has dripped so much it's nearly coating the front of his beast briefs. He look infatuated with you, and you feel the intense desire to breed with him... regardless of how you do it. Your golden brown fur shines in the light of the room, both of you stinking but him much worse than you. The stench is incredible, and you feel so many different desires flooding your mind at once.
Before proceeding, you turn around and begin to purr, leaning over and sighing in pleasure as the turd from before is joined by so much more shit. Lion turds burst and splorch out at incredible speed, assaulting the back of your diaper with your stinkiest and fattest dump you've ever had. All of the pushing and grunting has worked up a sweat, and you feel much stinkier now as your musk drips from your entire body as thick globs of grease. "Damn, you're really getting into it..." The rottie compliments, a swift and buff paw spanking against the back of your messy diaper and making you blush deeply in pleasure. Only now does it occur to you that your long hair and skirt makes you seem like a naughty bottom. The rottie seems to have picked up on it, still jovial but much more naughty as you feel the front of his diaper bulge grind against the back of yours, squishing your mess against your ass hard as the stench fills the room.
Without looking back, you can hear the door open, and a few other men in their own diapers enter the room. You and the rottie continue to grind together as they approach, the pleasure of unloading a fresh dump and having it humped across your fat feline booty is too good to bother looking, and you can only assume what will happen next...
