I knelt on the floor in darkness, the blindfold strapped to my head keeping out all light.

My hands twisted nervously in the leather cuffs that kept them locked and secured behind me. A similar pair of cuffs were locked around my ankles.Not for the first time that day, I mentally cursed myself for not just taking my lumps and reporting this whole sordid affair. After all, it wasn't like the university was going to fire a teacher over watching porn in his own office. Embarrassing, certainly. I might not be able to look certain colleagues in the face for a long long time. But I don't think I would have minded being a recluse. More time to myself, certainly. And it would have avoided my current predicament as well.

Because, it seems, I had been spotted. Found out. I had no idea how. All I knew was that a couple days after the particular event in question I received a snapshot of myself in a rather compromising position, with the screen of my computer on display as well. The demand had been simple. No financial benefit, nothing too insane. The woman, for I had to assume it was a woman, wanted to play out some of the scenes she had watched me enjoy. An odd request? Damn right. But at the time it had seemed like a no-brainer. Let her have her fun, a couple meetings, and then the blackmail would come to an end. She would tire of it, or simply agree I had held up my end, and that would be that.

If only she shared my logic. If only she had been a run of the mill blackmailer out for a quick buck, or a one time thrill.

I heard the door to my office open, and the click-clack of heeled boots enter. Even after all this time, I still had no idea who was doing this to me. I was always blindfolded or hooded during our little play sessions. She rarely spoke either, and it was not a voice I was overly familiar with. I squirmed a little in my bonds, then stilled as I felt the tip of a crop run down my naked chest.

A chair was pulled up in front of me. I felt her hands bring a leather collar, my leather collar, up to my throat and buckle it on. Her fingers spent a few moments tracing it in place, before snapping a leash to it. I felt her pull the leash down. Down. Down. Then I tasted rubber pressing against my mouth. I moaned as she pulled me further down, my mouth engulfing the first couple inches of a strapon. I didn't need further instruction, this was not the first time she had done this to me.

I began to bob my head up and down, moaning. She liked it when I moaned. Somewhere in the room, I knew, a camera was recording. As it always did during my sessions with my anonymous blackmailer. If I could have gone to the authorities at the start, there was no way I could go now. Dozens of clips had been shared with me already, illustrating the absolute hold she had over me and my life. There was never a hint in any of them as to her identity, just very clearly me pleasuring her and myself, or worshiping her, or sucking her strapon as now, or another half dozen kinky humiliating tasks. All ready at a moment's notice to flood the inboxes of my colleagues, and my bosses. That would certainly see me disgraced and let go.

Soft fingers traced along my face and neck as I continued to bob up and down. I had learned not to put up a fight, as that only led to more restrictive bondage our next time. Once it had led to two weeks locked in a chastity device, with pictures of the key sent every day along with a list of tasks to complete to win freedom from the lock. That had been excruciating, and did not bear repeating. No, I behaved now for my anonymous blackmailer. My mystery mistress. 

I moaned into my mouthful of rubber cock as she began to methodically spank my rear with her crop. I wondered if our game would stop when classes ended for the Christmas break. Nearly a month off and away. Surely she had to be getting tired of this whole thing? At some point, I would be left alone?

As she took hold of the back of my head to encourage my sucking, combined with a steady spanking rhythm, I felt doubt niggling at the back of my mind. Perhaps not. Perhaps this was to be my new work life. A blackmailed bondage slave to some woman who, for all intents and purposes, owned me lock stock and barrel.

I moaned, and heard her softly laugh.
