"Vorarephilia (often shortened to vore) is a paraphilia characterized by the erotic desire to be consumed by, or sometimes to personally consume, another person or creature, or an erotic attraction to the process of eating in general practice. ... The word vorarephilia is derived from the Latin vorare (to "swallow" or "devour"), and Ancient Greek φιλία (philía, "love").
The fantasy usually involves the victim being swallowed whole, though occasionally the victims are chewed up, and digestion may or may not be included. Vore fantasies are separated from sexual cannibalism because the living victim is normally swallowed whole." -Wikipedia
