Tentacles are commonly used for kink purposes, both commercially and in fandom. Probably the most infamous use of tentacles is with the tentacle monster from anime, which has inspired much fanart and fanfic across a variety of fandoms as well as influences in other commercial mediums, though various types of tentacles have been used in many fandoms.
Tentaclefic is fanfiction that makes use of tentacles in some form. Fanworks and commercial works in many mediums make use of tentacles.
Origins and Commercial Examples
The most obvious and famous example is Urotsukidouji aka Legend of the Overfiend, the progenitor of the tentacle hentai genre. Another manga from the same creator, Demon Beast Invasion, is also a famous example. The genre is sufficiently old and diverse in Japan that it has spawned numerous parodies such as La Blue Girl, an anime about a sex ninja who uses her powers to battle tentacle monsters. Commercial examples tend to feature female victims and nominally male monsters, though female monsters are also somewhat common, and male victims are not unheard of. Many other kinks are commonly found along with tentacles, including inflation, pregnancy, guro, and body horror.
Outside of tentacle porn, tentacles also make an appearance in slightly less overtly sexual ways in many types of media. Superhero comics and their adaptations feature many characters with tentacles, whether organic or mechanical. The SGA episode "The Seed" also features tentacles.
The tentacles can belong to creatures, such as the tentacle monster. In these cases the encounter is often combined with non-con or rape kinks, known as tentacle rape, as the penetration is involuntary. Often, the creature is either an amazing lover or produces aphrodisiac fluids.
The tentacles can also belong to machines. This can be non-con, but can also take the form of elaborate sex toys. For example in some Stargate Atlantis fic, Atlantis can provide tentacles as sex toys that react to the thoughts of ATA gene carriers. Mechanical tentacle arms are common in superhero canons.
Sometimes the kink can be voyeurism when the other half of the pairing witnesses the tentacle violation and is turned on by it, or the tentacle monster acts as an AMTDI device and makes them have sex too.
A different kind of tentaclefic is a subgenre of an alien kink in science fiction stories, in which aliens have genitals different from the human norm, that are or come with tentacles. This can be canon, like in Babylon 5 for the Centauri, or fanon as in Star Trek: TOS K/S for Spock, who is frequently described and depicted with genitals that are alien to various degrees, including tentacled versions. For more detail, see Vulcan Genitalia.
There is also the option that a normally non-tentacled character (temporarily or permanently) grows tentacles and uses them for sex.
Especially works with alien kink or temporary tentacles may feature characters consenting (often enthusiastically!) to tentacle sex, in contrast to tentacle rape. Such works are sometimes tagged "Consentacles".
Humans With Non-Sexual Tentacles
Due to a genetic mutation, some female and male characters in the Sime~Gen fandom have tentacles on their arms. They are used for "feeding" and bonding to other characters, both opposite and same gender.
While the tentacles are technically not used in a sexual way, there is a strong undercurrent of sex, both consensual and non-consensual, in these fanworks.
Fandoms with a lot of tentacles
- Harry Potter - the Giant Squid under Hogwarts lake doesn't inspire a lot of fic, but it's often mentioned in passing in other stories.
- Batman comics have canonical tentacle monsters, and Poison Ivy has tentacled plants that feature in many stories.
- Marvel Cinematic Universe also has villains (and sometimes heroes) with tentacles.
- Cthulhu Mythos and writings of H.P. Lovecraft are frequently associated with tentacles, though some fans argue that this association is exaggerated and that tentacles don't appear that often in Lovecraft's stories.
- Any fandom with a lot of aliens, mutants, or weird unexplained events may inspire tentacle fic.

Other types of tentacle fandom
In other circles, this type of kink is often called GOT for "Galaxy Of Terror", the title of a 1981 cult film as well as a website devoted to the kink. The GOT community tends to be heavily male with an interest in superheroines and Western science fiction as well as commercial tentacle porn. This community produces fan art and fanfic as well as original erotica.
