So there's definitely a trend of the author pushing the boundaries to see what he can get away with in a non-H series, first it was just mc falling into tits To Love-ru style, then it was him stripping them for whatever reasons and/or the FLs pulling him onto them, recently it's been them stripping him & getting cock-shocked, & now it's "haha it looks like he jizzed all over them but we swear that's not what happened lol". seems like pretty much the only steps beyond this are "okay he did actually jizz on them but they didn't fuck, promise" followed by Tsugumomo-style "okay they ARE fucking but no penetration, we would never break your rules mr publisher we swear lol" shit but this series doesn't have the fantasy staple "they need to transfer mana" excuse (thanks, FATE) so I really wonder how they'll manage to get away with it, lol
