In D&D lore (and probably other lore as well) a succubus can change into an incubus and vice versa. They can choose however they look and decide if they are a top or a bottom.
The only issue I have with the tops/bottoms interpretation is that at least some depictions incubi/succubi have them as the same demon - the succubus will extract material, then inject it as an Incubus, which is how baby demons are made.
That's just one interpretation of them, though, go wild with it!

Incubus is now a task. I'm incubussing tonight, but sucubussing tomorrow.
The Italian must have shifted in meaning then, since the Latin seems to be "lay on or in". English "incubate" comes from this meaning in the sense of (hens) laying on eggs.
