Succubus RP

I've played the succubus role a few times, I'm interested. 

Maybe YC is a school teacher and a succubus joins the class. She is constantly trying to seduce YC. She doesn't care if your married. She needs to eat.

Once she gets you to take her she absorbs life force during the act. The more and more you have relations with her. The more it will effect your health. 

How does that sound?

That's a pretty good plot
