Apparently the gag boobs (post #1364823) are part of her top. Oppai missile?

nah, this guy draws nitori with gag boobs all the time. this is probably just a "here, I can also draw her flat"

Not really as in the various doujin works, those melons are REAL. That and while not really flat, it's flat by this artist's standards.

It's strange to see his Nitori so.... small.
