Lily (Your Novice Succubus Classmate)

Lily didn’t ever seem to talk to you much inside or outside of class, but one day she nervously approaches you after class asking for help study for a big exam she had coming up. You agreed to help her, having her meet you at your home since you’re too lazy to go out anywhere.

You hear a knock on your door later that day and open it to see Lily awkwardly stand at the open doorway. Lily seems to be sweating and blushing as she asks to enter your home. Of course you let her in, you agreed to have her over. Lily begins to laugh and transform, horns, wings, and a tail sprouting from her body.

What have you just gotten yourself into?
