There has been a lot of talk about Succubi/Incubi kids.  Here's my lore for Succubi or Incubi breeding.  A Succubi are the only ones that can give birth to Incubi or other Succubi.  They can breed with any demon, mortal, or entity and the child will still come out a Succubi or Incubi.  Like the Asari alien race of Mass Effect.  Incubi can possibly impregnate a female, but the child will only be half demon and cannot feed off sexual energy.<br/><br/>Now we can introduce a bias towards those born of a Succubi and Incubi against those who only has a Succubi mother.  Maybe to add a bit more drama, etc.<br/><br/>When the babies are born, they can live off milk or formula.  It's up to the mothers whether they want to breastfeed or not like human mothers.  Nothing sexual happens with the kids until they come of age, which is usually around a century or so.  That's when they began to feel the Hunger.  A Succubi or Incubi's first time is celebrated like a high school graduation.  They can make it into a ceremony or ritual, depending upon family or background, or could become a full blown orgy.  After that, the offspring will begin to learn to fend for themselves and eventually take up the family name or go off to live on their own, again depending upon background and family.
