Prosthetic tits

Boobpedia - Encyclopedia of big boobs

Prosthetic tits are latex moldings that a model wears over her actual chest, comparable to movie props that actors wear in films. This is an extreme rarity in the adult entertainment industry. Zena Fulsom (who served as an experimental model in this field) and her "sister", Cindy Fulsom are the two most famous women to use prosthetic breasts.
