Spiderman Herself (Patreon)

Transformed into a girl, Spiderman vows he will never wear a bra. "I guess I'm a feminist now," he explains to Spiderwoman, who smirked and nodded. "We'll see," she said, glancing at Peter's bust and thinking, I give him a week. Less if he has to do a lot of fighting.

Then, after a moment, Peter stepped closer and whispered, "but is there such a thing as a bra for my butt? It just keeps-- jiggling."
