I just realized that I never updated this story to let people know (oops), but I've started a "reimagining" of Succubus Tail called Succubus Tail: The Under Side! It's not exactly the same as this one—in fact, it quickly diverts into its own very different story. One that I hope is a fair bit better. It does begin with the same initial premise, however: a young college/academy student gets transformed into a succubus by their own demonic summoning spell. It's been a ton of fun to write, and unlike this one, I expect it'll end up being quite a bit longer.
