Animal transformation fantasy - Definition and Overview

Animal transformation fantasies are a common theme in fantasy and erotica. In these fantasies, human beings can change from human form to animal form, or behave as animals.

Examples include:

• Furry
• the fantasy of lycanthropy (wolf) and some versions of vampirism stories (bat)
• human pony-play and other forms of sexual role-playing

The transformation of a human to animal form is often depicted as sweaty and painful, and often includes 'rippage' (clothes tearing apart in the course of change). The transformee's body also bulks up in muscle mass and sprouts excessive body hair which develops into fur. If the 'transformee' were a woman, sometimes extra pairs of nipples are shown growing on her stomach, as in An American Werewolf in Paris. Such transformation process has elements of 'wet' fetishism, trichophilia, and sado-masochism.
