I made my way back to my room in a daze. I didn't know what had hit me or what had come over me. I had given myself completely to this woman and I could still feel her hold over me. Even if I had tried to put her out of my mind, the presence and weight of the chastity device locked around my cock was a constant reminder of the hold that my Mistress had on me.
The next day I tried to go about my business as usual but no matter what I did my mind kept returning to the session that Mistress had spent training me as her slave. I could felt the pain of her punishment, I tasted the leather of her boots as she made me lick them, and I remembered her cold dismissal of me when she decided that our session was complete for the day.
Most of all though, I felt her control over me. Even when I was no longer in her presence, I still wanted to please her. It was like I had taken a drug, I had felt the power of submission, and now I needed more of it. Although part of me wanted to cum so badly, another, a bigger, part of me wanted my cock to stay locked up as that would increase my torment and increase my submission to my Mistress.
The time between the end of my training session and the first time that I would see my Mistress in class again was like torture. I craved to be in her presence again; I craved to submit once more to her will.
What had she done to me? My being belonged to her now I realized.
Two days later I walked into her class and it was jarring to see her dressed in her normal clothes again. She was no longer a leather-clad dominatrix, but was instead back to being a sexy professor in a conservative, professional outfit.
I glanced nervously at her as I walked in but she gave no indication that anything out of the ordinary had taken place between us so I sat down in my normal seat.
"Now class," She began, "Today we begin our section on female domination. This will be the study of women who control all aspects of the sexual relationship with their partners."
I hand came up indicating a question and I looked over at who was asking it. I saw that it was Emily. She was one of the most attractive girls in the class and I had masturbated while thinking about her many times before.
