Such a distinct smell, you can't quite understand why you can relate that exact idea to the smell you're smelling, at least until you start feeling something entirely new. With the slime nearly halfway inside your belly, with your gut pressing against the ground and your arms and legs still held in the air slightly, you begin to feel a sharp popping feeling come from your ass. At first you blushed incredibly deep, thinking you actually managed to shit around the slime's insertion, but you slowly realize you're growing a tail!
The sensation is over in a few minutes, and your new fluffy wolf tail wags on the outside of the slime, with a lot of it still pushing into you. As the slime loses more mass, you finally feel it split in two, with the frontal half slowly continuing to flow down your mouth, and the back half slowly pumping up into your ass. Only now does the incredible pressure of having such a swollen belly make you feel uncomfortable, your tail ceasing to wag as you lose most of the pleasure. With your arms freed now, you are unsure at first if you should pull the slime away from your mouth or off of your ass. At this point, you just slide across the floor until your back is against a wall, trying to sit comfortably while your intruder continues to fill you up with itself.
After a few minutes, the slime is finally entirely inside you, and you groan at the sight of your obscenely large, hairy belly. Only now do you realize that the smell from before is gone, and ever since you grew out your tail, you didn't seem to mind it. The thought of it crosses your mind again, curious as to why the slime smelled so... gross, but tasted just about as 'nothing' as water. As you continue to think about it, your belly seems to shrink slowly, and without noticing it, the fat spreads to different parts of your body, soon becoming muscle and... fur.
You are shocked out of your thoughts when you look up to see a muscular, and incredibly musky werewolf staring down at you, wearing nothing but a vest and a brown diaper filled to the absolute brim with fat loads of shit. Instead of groaning in disgust or trying to run, you instead feel an incredible desire to get on your knees and sniff at the disgusting diaper.
"I'm glad you could see things our way. This house has many twists and turns, enchanted with magic, and, well... creatures you would never believe existed." The werewolf spoke down to your muscular and fat self, watching your tail wag as your skull was the last thing to change, morphing to the shape of another werewolf's muzzle. Your long hair was much wilder now, but still just as long, dangling by your thick pecs and beefy arms as you lean over on all fours to get a sniff at the bigger werewolf's crotch. The stench was strong, and would have previously forced you to cry in disgust, but now it smells like the most delicious kind of sex, or meal. Your skirt looks much smaller on you, now only covering the top half of your bubbly wolf cheeks, and honestly just making you look incredibly cute.
"But I can clearly see that you already found that out..." The werewolf chuckles, squatting down to look into your bright yellow eyes with his own crystal green eyes. His messy diaper was so full that it squished against the ground, spreading across what you imagine to be his huge wolf ass. Out of the bottom of your vision, you can see his cock tenting the front of that nasty, used diaper, squished against an entire load of wolf poop as if he shit and turned the diaper around, then shit again. Speaking of, you can hear a loud crackling sound and look down as gas and even more shit escapes the bigger werewolf's hole, filling the diaper more and straining it slightly. His incredibly thick musk and potent stench bombards your nose, smothering you in scents that feel like heaven to you now that you have the right nose to appreciate them with. You can't help but drool as you look back to him, noticing him drooling just like you, panting, and blushing. Who wouldn't after pooping yourself right in front of a muscular, attractive werewolf in a skirt like yourself?
