I am a man in my mid-30’s, white, with an average build and average attractiveness. I have a large, very thick cock. I have gone into a massage with a new masseuse named Kateri. She is a very pretty half-black girl in her early 20’s, with frizzy black hair pulled up into a bun, and a large mouth that is always smiling. She is 5’6", with the body of a yoga enthusiast and large, very perky breasts. She wears yoga tights and a loose tank top and sports bra. Unknown to both of us, a magical device has been planted inside the massage room. Neither of us know the device is there and we never discover it. Kateri just feels compulsions building, but does not know why. When I roll over halfway through the massage she briefly glimpses my naked dick and starts to feel the compulsion build. The device causes Kateri to feel compelled to put my dick in her mouth and suck it until it cums.She knows it’s unprofessional and fights the urges for a long time, and almost succeeds, but eventually it starts to feel like an invisible force is literally forcing her mouth open and pushing her head down onto my dick. She tries to apologize and explain what’s happening, but can’t get the words out with my dick in her mouth. I start to dirty talk to her, given them I’m white and she’s black, my dirty talk takes on an increasingly intense racial element, which Kateri finds both shocking and extremely exciting. Tell in great detail with lots of dialogue. Tell in the style of a thriller novel.
