Hentai anime features many genres like heterosexual relationships are known as yaoi, and yuri which focus on the female homosexual interactions. There are plenty more other different sub-niches - bakunyu, the depiction of women with big breasts, futanari, depictions of hermaphrodites, tentacle erotica, the depiction of tentacled creations and sometimes monsters. Let’s talk about last two in details.
Tentacle sex is a bizarre niche of anime and doujinshi in which women are gripped and penetrated by weird monstres with tentacles. Asian shokushu goukan is a concept found in many horror hentai titles, where various tentacled creatures (usually fictional monsters) attack or otherwise penetrate women, dickgirl and, less commonly, male. This niche is very popular in Japanese erotica.

Tentacle erotica has roots in classical asian art. In painting ‘The Dream of the Fisherman’s Wife’, a nude woman is graphically attacked by a pair of tentacles.

Tentacle erotica has a strong influence at the anime world. Lot of hentai anime and manga have been turned into live action tentacle movies. Many well known AV idols like Maria Ozawa, Haruka Sanada, Sasa Handa, Yuka Osawa acts in well known Touch of Tentacle Orgasm live action tentacle series.
