Anal Monster Birth

This game features scenes where it's characters give birth from the anus, through anal viviparous birth, to any kind of non-human creatures or monsters during the course of the story.
In case of anal eggs laying just use Anal Egg Laying.

Important note: Only use this tag if the birth of the baby monsters are part of the story. If it's just implied or covered by a time-jump and only the result (e.g. monsters are running rampart where there were none before) is shown, then do NOT use this tag!
