The act in which a character births multiple characters/creatures at the same time from a single orifice, rather than the typical one-by-one .

Notes:

• Birth must come from a single orifice (i.e. pussy, nipple, etc.). Having each breast birthing one character, for example, does not count as unison birth.
• Often involves interspecies pregnancy, infestation, or hyper belly
• Falls under the multiple_birth tag, but allows for a more specific search of this type of multiple birth.

If the character is laying eggs rather than live birthing, use the unison_oviposition tag instead.
