It's so funny to me when you have "almost-hentai" mangas that have poorly disguised porn plots and they end up taking the story way too seriously even though everyone is just there for the H scenes. This one is just "nah just straight up porn plot" to the point I was almost sure this must've been an eroge adaptation.
The problem is, of course, that it is in that limbo of being way too sexual for a normal manga, and too censored for a hentai. But it seems it is goint into fetishes so it might be a lil interesting
