mechanical pussy
The character is a cyborg or android with mechanical, robotic or cybernetic female genitalia, the nature of which is obvious, for example, if the character is partially disassembled, damaged, shown through an x-ray, or an organ has undeniable external signs of artificial origin. At a minimum, if the genital module has a visible border on the skin, separating it from the rest of the body.
Also suitable for single images of cybernetic or robotic female genitalia intended to be mounted as part of a robot, android or cyborg body.
The tag is not used for an artificial vagina, which is just a sex toy.
The tag is not relevant if the artificial nature of the pussy is implied by the nature of the character, but not visually.
