Kubo's an ass for being so rape-y, but I'm also kinda rooting for him being able to keep his friends off of her (which given the title... probably not going to happen).
Well I dunno if there's more out there untranslated but this is some strange shit. Huh, so where exactly is the NTR? Is this a time race for chad to completely make the teacher his bitch before she gets banged by the rest of the squad? Because there's no cuck, wimp or anything so far that chad has to compete against. Or is the guy from the start supposed to be the victim here? He has just as much presence as anime parents and their overseas trips. Inb4 the NTR in the title is for chad to be cucked by the wimp... Well that would be quite something.
