[[Oral]], [[vaginal]] ([[penis]] if male or [[futanari]]), or [[anal]] penetration by [[tentacles]], to mimic the act of [[sex]]. Colloquially known as "tentacle rape".

[[Tentacle sex]] is considered separate from [[sex]] (with a [[penis]]), [[object insertion]], [[interspecies]], and [[bestiality]], and should not be used with those tags. However, it can and should still be tagged as [[vaginal]] or [[anal]].

Don't use this tag if the tentacle is just about to be inserted, but hasn't penetrated yet. Use [[imminent penetration]] instead.
