Eroi Kuma's manga / #confused(4)

I'm not saying that I dislike it, but I'm just wondering where the logic is? A grown man who seems very strong gets nailed down by a high school kid who is like half of his size? I mean by the looks of it the bottom could yeet this tiny shrimp with a single arm

I normally don't mind a story with rape, but the story didn't even make sense. So many things happened and the guy who didn't even want to shake the hand of a guy who kissed another guy got pretty quickly over the fact that he was now raped and threatened by the same guy

This story sucked harder than any bottom ever has
