Make a deal with the Demon.

"Fine. I'll forge a contract with you."

He nods and offers you a hand to help you. A bit reluctantly, you take it and stand back up. "Excellent decision. I have a feeling that we'll get along famously my dear."

"Right... And? Do you have a name? You seem to know mine, but I can't keep calling you 'demon' forever."

"Hm. I don't, actually. I might have had one, but spending a few centuries inside a mirror can muddle your memory." He thoughtfully looks up at the ceiling. To be honest, if it weren't for his strange entrance you would never have thought him to be a demon at all. Actually, you begin to question if he's even all that dangerous. So far he's been acting quite well-mannered and harmless. "I'll call myself Kris for now. Yes, Kris will suffice for now."

"So... Is that it now? We have a deal?"

Kris laughs. "Not at all. We're just getting to the fun part Casey." He places his hands at your waist and pulls you right up against his chest. "You recognized one of my other labels, didn't you? As an 'Incubus'. And I told you that I need 'lust' for power... In order to make a contract with me, you have to offer your body to me."

You gulp. "Y-You mean..."

"We need to have sex. Well 'Master'? Last chance to change your mind... Though I honestly wouldn't recommend it at this point."
