I want to suddenly lose the ability to walk on two feet and have my butt, hips, and thighs grow to jiggly proportions so that every step I take causes them to wobble. I want a puffy donut anus that drools lubricant and winks spastically. It'd be big enough that it's constantly on full display no matter how hard I try to hide it. And I'd give off pheromones that encourages any male, human or otherwise, to fuck me and dump their seed inside my ass. This is what I want more than anything in life.
