Chastity magic gives me...
Chastity magic gives me the power to tease and torment you in ways you couldn't imagine.
I call this one "the waterfall."
One spell gives you a never-ending blow job. A second spell turbo-charges semen production in your already tight balls. A third ruins your orgasms.
The final spell directs the near-constant flow of creamy ejaculate into your mouth. Swallow every drop, or it gets worse.
How long am I going to keep you like this?
As long as it takes me to think up your next torment.
