Hentai fetishes - Futanari and Tentacle art

Hentai is a Japanese word that used when referring to sexually explicit or pornographic manga, animation and computer games. The word hentai is mostly used to mean – sexual perverted.
Hentai anime features many niches like heterosexual interactions are known as yaoi, and yuri which focus on the woman homosexual relationships. There are much more other different sub-niches - bakunyu, the depiction of women with gigant breasts, futanaries, depictions of hermaphrodites, tentacle erotica, the depiction of tentacled creatures and sometimes monsters. Let’s talk about last two in details.
Tentacle erotica is a bizarre niche of anime and manga in which women are catched and penetrated by weird creatures with tentacles. Japanese shokushu goukan is a concept found in many horror hentai titles, where various tentacled monsters (usually fictional monsters) catch or otherwise penetrate women, futanari and, less commonly, male. This niche is very popular in Japanese sex fantasies.

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

Tentacle erotica has a strong influence at the hentai world. Lot of hentai anime and manga have been turned into live action tentacle. Many famous AV idols like Maria Ozawa, Haruka Sanada, Sasa Handa, Yuka Osawa acts in well known Touch of Tentacle Orgasm live action tentacle series.
Other popular Japanese fetish is futanari. This fetish depicts hermaphrodite anime characters. Other common words used to describe futanari characters are dickgirls or hentai shemales (but terms dickgirl and shemale is incorrect). Futanari, along with term newhalf, are more common terms.
Originally futanari referred to any hentai animation and movies character that having both man and female sexual signs.
The term futanari is usually reserved for characters painted in Japanese hentai anime style. Western art is usually simply referred to as toons dickgirls.
