And it is as smutty as Satan intended it.
Nothing else to see here. See you next episode.
But since I promised myself I’d give every episode my very best let me say this: It is tremendously facetious of the show to keep “characterizing” Araragi Koyomi as someone who is “normal” – as someone who wouldn’t be seriously into children, his sisters, etc. by making him say he isn’t at the same time exploit every situation he’s with them by making them naked, showing their crotches, and having them play out pornographic scenes substituting elements with supposedly non-pornographic items (which just makes it dirtier).
I am performing this innocent totally non-sexual game which is totally unfair but that’s okay since I am upfront with it so as to protect my innocent little sister who is now possibly close to the perfection that is the body of Hanekawa Tsubasa because and only because I want to protect her from the perversions of Suruga Kanbaru.
This is the courage of being meta.
Nisemonogatari shows incredible commitment to being smut: oral hygiene for a whole can of foreplay involving toys and oral sex. The very idea that it uses cleaning one’s teeth as an incestuous hentai scenario makes it the fucking god emperor of smut in mainstream anime.
STOP SMUT! CENSOR NISEMONOGATARI! WHY CAN’T ANIME BE MORE LIKE DISNEY!?! SIEG HEIL!!!
