Tentacle erotica

Tentacle erotica (触手責め, shokushu zeme, "tentacle attack") is a type of pornography most commonly found in Japan that integrates traditional pornography with elements of bestiality, fantasy, horror, and science fiction. It is found in some horror or hentai titles, with tentacled creatures (usually fictional monsters) having sexual intercourse, predominantly with females or, to a lesser extent, males. Tentacle erotica can be consensual but mostly contains elements of rape.

The genre is well known enough in Japan that it is the subject of parody. In the 21st century, Japanese films of this genre have become recognized in the United States and Europe, although it remains a small, fetish-oriented part of the adult film industry. While most tentacle erotica is animated, there are also a few live-action films that depict it.
