I don't see the girl completely resisting or honestly putting up much of a fight so to me it isn't really rape, it is more forced until she gave into the pleasure. I don't get the whole loli and pee thing though, like is it that common for little girls in Japan to just piss themselves? No judgments since the bladder can have a mind of it's own, but I suggest a diaper? I enjoy age gaps, I didn't think it was that extreme. The girl looked to be at least hitting puberty. I enjoyed this manga in it's entirety, I have read it a few times and it is always good, but obviously it will NOT be for everyone.
