[Boxphilia Engineers (Thomas TABAYASHI)] Futari wa Rival [Digital]

Apparently, this is classified under "ryona" genre, a type of sexual fetish where the MC (or FMC) is subjected to physical or psychological abuse from another. Idk but some sick fucks out there has this kind of kink in them that feels satisfaction from hurting others (kinda related to sadism in a sense but indirectly, and usually just involves fictional themes as opposed to BDSM where it is physical in reality). I kinda like this for other reasons, simply much like a typical boxing doujin.

How is this even on nHENTAI? There's nothing adult about this. MAYBE if they were nude but all they were doing was boxing.
