Dick shrinking spell

Oh, what a big throbbing dick you have. You've been aching to stroke it in front of Me. I told you I'm a witch, but you didn't believe Me. Here, watch this. I'll gradually make your cock smaller and smaller until there's nothing left to stroke. You realize only I hold the power to turn it back to its former glory. Where is your pride now? That's correct: It's lost until I give it back to you. Maybe you won't be so arrogant next time, slave. You'll just have to do as I say, and maybe only then will I give you back your manhood. How dehumanizing is this! I won't even consider turning you into a woman. You are just a weak sexless toy now.
