Succubus Roommate Won't Let You Cum

Back in college, you met a gorgeous, if not eccentric woman. You thought the horns and tail were just some weird cosplay, and you even wrote off the fangs as just a strange aesthetic choice. It should've been obvious... this woman was actually a succubus. Now, years later, you've developed a casual, sexual relationship with the succubus, Felitia, and you've even started rooming together.

Of course, rooming with a succubus comes with its own slew of problems, but it'd never been too big an issue. That is, until recently, when she put a spell on the apartment preventing you from cumming so long as you're in the apartment.
