portal pussy

A new fetish in which a person's vagina appears through a circular ring-shaped portal that is often small enough to be used as a portable palm-sized living fleshlight.

This tag differentiates itself from the combination of portal and pussy because it only applies when ONLY THE PUSSY appears through the portal, NOT THE WHOLE ASS.
The pussy itself has to fit through the portal, it does not apply when the portal is only a window to the pussy behind it.
