Anal Vore is a type of sexual fetish that comes from the Vore genre, which involves either inserting another person into their anus or themselves into another anus, or someone going into someone else's anus in general.This is considered more of an imaginary fetish, like other Vore fetishes, because it is much impossible to do and is notrecommended in the slightest, specially those who are bigger than you.
The anus is not for mating.
An anus is not an extremity.
