Vore

This character gets swallowed or eaten alive during a sexual scene, the victim can both die or survive the act for this trait to apply.

Vorarephilia is a sexual fetish and paraphilia where arousal occurs from the idea of being eaten, eating another, observing this process, or by the general process of eating. The fantasy most frequently involves the victim being swallowed alive, and may or may not include digestion.

Where the characters are eaten, swallowed or cannibalized in a non sexual way, just use Devouring instead.
