Yep, gotta love Hentailand where literally nothing makes sense. The majority of silly plots seem to come from NTR in general too. They're usually ridiculous, apparently talking and common sense is totally absent with no repercussions to allow the sex to even happen.
Next silliest are ones like literal skin suits that genderbend the wearer and then get fucked by other dudes, only to then slip out of the literal skin suit. And then the REALLY completely out there ones where a ninja lady crushes, ahem, CRUSHES a dude's head in her pussy with her vaginal strength and spins around like a helicopter.
