Well, as long you find a way to keep the dialogue as interesting as you did with the Cow Succubus, I doubt if anyone will complain about the design.This is a good question.
I might use these scenarios for sure (like drugging the MC), but I won't go too much into monster girls, like "gargoyle succubus".
I don't want "Succubus Monster Girls" so to speak. That doesn't mean that I won't use some of these scenarios, but they will be adapted to the lore I created.
After all, who doesn't love being dominated by thick women?
