Goat Pancake
“Catty?! wait hang on, Dr.Alphys is testing something on me, my body won’t act nor- Mmph!” Asriel was able to eek out before he felt the alley cat’s cheeks collide with her own as she backed up trying to wedge his face deep into the clothed canyon her hefty ass made whenever she slipped into her snug overalls until the back of Asriel’s head met with the wall, that’s when something strange happened. Instead of feeling the goat-boys face being pressed more firmly against the seam of her overalls she instead felt a warm sensation spread out around the inner-sides of her cheeks, curious she turned and saw a strange and humorous sight, Asriel’s face flattened out against her rear while his hands tried to push back against it in an attempt to free himself.
“Oh. My. God. This is so hilarious!” Catty laughed out as she pressed downwards with her wide ass squishing the goat boy flat against the ground before standing back up to giggle at his squashed form before getting an idea and stripping out of her overalls and panties, freeing her ass and jiggling it right above the welcome mat of the goat causing him to blush hard and turn his snow-white body to turn a very light shade of pink as he attempted to get out a word only for the cat-monster to once again plop her wide ass down on top of his flattened form and grinding downwards, trying to get the goat as flat as possible before standing back up and turning around to see her handiwork only to find Asriel’s discarded clothes prompting he to look around for a bit before finally looking at her rump to see Asriel’s fluffy furred body flattened and adhered right against her ass, the sight of which made the feline monster giggle at the goat boi’s current predicament while she gathered up her clothes and began to walk away with him in tow, whether he liked it or not. “Since you’ll be sticking around I guess I’ll have to entertain you, don’t worry, I’m sure me and bratty can think of a lot of different ways to play with you cutie~”
After a while Alphys would finally return with a serum that should cure her assistant’s little situation, alas, she could only find his clothes and notebook, both of which looked as if they had been through some wear and tear.
