Succubus that stick out long tongue is a classic. Thick tongue, serpent tongue, stretched and more. Also add poses where she licks her fingers with her 10cm tongue and licking their teeth and/or lips, and so on.

Succubus with fangs, which can be hot, also a classic. Additionally customize whether fangs go within or without (specifying which overlaps the lips, upper, lower or both... the most common selection would be upper, both or neither... but who knows, maybe orc succubi could be a thing if only lower is selected).

There is no mention about any of this (unless Steam's search discussion bar is broken).
