Partial unbirthing is the act of inserting one's head into the vagina and through the pelvis. It is a fetish that is extremely rare, probably one of the rarest of all sexual activities. The reason for this is that to be mutually enjoyable it requires that vagina stretches to an enormous size. The woman must also have a huge justo major pelvis. This condition is where the minimum pelvis size is enlarged uniformly in every direction by a linear factor of 1.5, or more than the average 11-inch wide pelvis. This 16.5-inch ‘or more’ Justo Major pelvic width is a condition that is only present in less than one in a thousand adult women. If these conditions are met partial unbirthing is possible. I can't provide links it seems. You can Google the articles below.

Partial Unbirthing
Additions to this gallery will obviously be very slow in coming. My apologies for that. I could use your help filling it though. If you know of more images of partial unbirthing that are real it'd be greatly appreciated if you'd share them or send links so long as they don't violate ImageFap's Forbidden Publisher List. If you are a couple or have a meet up and have done this, images would be greatly appreciated. Faces are not required. They can be obscured or cropped out. We simply want to add more images to the gallery.
