>succubi as stealing seed from men
at least they work for it instead sucking it from your testicles with a straw lol
>When succubi give birth, we never got to see it.
i've seen it. they don't reproduce like mammals because they can't menstruate, instead they have sacs that produce inside them. the embryo develops in that sac which has thick membrane(protecting fetal) and fluids, it can be laid out like an egg, or kept inside (whichever). the sac has small tight collum that can be expanded to receive male load (like handheld water balloon), shortly after it needs insertion of succs energy which starts the process otherwise it is a sac of stored energy. for practical reasons they don't bear the children instead they bring the sacs to their nursing chambers (as the sac requires energy, and in my understanding succ can be bred in almost an instant given enough energy), and more importantly the nurses can teach the developing embryos before they reach toddler stage.

If she wants to come in, she can.

Tell us more about succubi biology. Are the sacs used for storing energy the ones they use to feed? Do they have other ways of feeding? Can they store energy in other ways(IE getting fat)?
