Womb

The most important organ of all!
  Every single slut has at least one womb. That is, a pink plushy organ whose primary purpose is to be impregnated by You. For nanosluts in particular, these may be brainwombs, organs which are simultaneously brain and womb, and the only major organ in her body. For greater sluts the primary womb is in the belly, with its cervix pointed upwards–connected to the throat and neck, enabling face-fucking impregnation. Many sluts can spontaneously generate wombs in other parts of her body in response to Your Godcock, such as a lungwomb forming from lipple fucking, or a cunt-womb from cunt-fucking.
 

Common Variations:
  Brainwomb
  Heartwomb
