When I first saw the booty, I had just initially thought my eyes were broken or something, lol. Like I somehow didn't notice her skirt, but it seemed to actually truly be, ^'butts in the open', lmao
If you take the cover into consideration, lipstick is also a delicious treat.
I'm pretty sure that's just another snack. Looks like a popsicle or something, or maybe a corndog sort of thing. I do see the resemblance though.
edit: On the other hand, it might be suggesting Hanamaru would make a tasty meal. Might even be true, going by how sweet she is.
edit2: Is this secretly a vore doujin? It's up to you to decide!
