“Welcome to the research study. Thank you for volunteering. You have read the information brochure for the study and signed the consent form. Are you ready to begin?”

“Yes”, you say, somewhat nervously, yet interested. The money you will get from participating is good. The study is to test and train an AI model to interpret brain images taken when I am looking at pictures. It sounds straightforward enough.

“Please lie down here”. The technician places the equipment around my head. The fMRI machine whirs and the gurney moves into the cavity. The machine is loud and a little alarming at first, but I have headphones on. The pictures start to appear on the little screen in front of me. First a waterfall. “I am looking at a pretty waterfall” I think. Then a deer. “I’m looking at a deer.” Apart from the noise, it’s pleasant enough and the thought of the money is attractive.

A picture comes on of a pretty woman and my immediate thought is that she looks like my hypnodomme. The picture lingers and I think of the latest trigger she gave me, that I would get aroused at seeing the colour red. The next picture shows a red car and my eyes widen for a moment. I try to think “I am looking at a red car” but my body begins to betray me; I’m flushed and aroused and my breath deepens.

The next picture shows another nature scene and I relax. But the picture after that is of a red fire truck and I begin to grow alarmed as I cannot keep from thinking about my arousal. With the next, also a red picture I feel the heat in my groin and I think of how she stands over me with her hypnotic eyes. I wish desperately for less red pictures, but by now my brain is picking out any bit of red from each picture and I can no longer control my thoughts of how sexy she is and how she said that the words “very good” would trigger me to have an orgasm. My face is flushed now as I desperately hope the AI model isn’t reading my  thoughts. I’d really like to get out from this equipment! In a surreal moment, the next picture just has two words written in red lettering.  VERY GOOD, it says.

I try frantically to lie still, but my body spasms with orgasm. Immediately the noise of the MRI stops and the gurney slides out. I’m relieved, but also a bit concerned that they may have cut the process short because I didn’t lie still.

A voice comes from the viewing room through my headset. “Thank you. You did well, except right at the end but we were almost finished anyway.” I recognize that voice! My domme comes out from the viewing room with a wicked grin on her face.

“My colleagues are going to love what I’ve taught the AI model today!” she says.
