You trusted a demon. Thanks to that little spell we shared and which you willingly cast with me; you're entirely under my control." The demonic trickster seemed engrossed with Aaralon's penis, "And your first task for me, well, after you've cum all over your fingers, is to steal Mistress Janna's ruby emerald for me."
