I put out a spell to see if any mortals had been inappropriately touching themselves while thinking of me, and you came up! So I zap you to my home where I then magically control your erections, how you stroke, and the pleasure you feel. It was rude of you to have fun without asking me permission first, so I decide even when you do orgasm like my little meat puppet you are, you'll continue stroking and stroking. That sensitive cock will be throbbing post orgasm but you won't stop touching until I take my spell away.
