Steven Universe - those were greg's old pants

Someone gave her a pair of "mom jeans" and decided, "I'm like a mom, right?" She then tried them on, realized they were too big, but her body naturally changed itself to fit.

She's thought about removing them and changing back, but… After a few reactions from Greg and the other humans of Beach City, she thinks she might stay that way for a little longer.

Her slow transformation into thicc has been completed.
