I come home to my apartment one day and find a large manila envelope with no return address in my mailbox. Curious, I open the envelope upstairs and gasp in surprise as an 8x10 photo falls out. The picture isn't terribly clear, but it's obviously me in the picture, lying back on my bed and masturbating, left hand wrapped around my cock, my body arched in pleasure, obviously building toward a strong orgasm.
After looking at the picture for a moment, I see the cuffs around my ankles, the collar buckled around my neck, and I realize that I remember the night this must have been taken, the fantasies I was acting out then, and I become very nervous indeed. If there are more photos--and there isn't any reason to believe there aren't--this one might look tame by comparison, given what I had done that night.
Several days pass, and then my fears are realized. Another envelope, this time with several smaller pictures, all of me in submissive poses, playing with myself in one way or another. After the last photo, I find a slip of paper with instructions typed on them:
"Leave your blinds open tonight. I want more pictures, you know the kind I want, slut. If you disobey, these pictures will find their way to your boss and your family, for starters. Let me urge you not to test me on this, my pet."
Despite my better judgment and my fear, I find myself incredibly excited by this...I've always had blackmail fantasies and even though this is much more serious I can't help but obey. My blinds are opened and I put the collar back on in front of the large window, then sink to my knees, masturbating in plain view, writhing in ecstasy, thinking of the cameras I am sure are following my every movement, bringing my fingers up to my mouth, sucking my own precum. Finally, after I cum, I crawl back across the room and into bed, stopping to cuff my ankles to the posts at the foot of the bed.
The next day I can't wait to get home and see what is waiting for me. I'm not disappointed--there is a videotape waiting for me with a label that simply says, "Mine" across it. With shaking hands, I put the tape in my VCR and see my performance, obviously taken from across the street, but clear enough to know who is playing with himself, how much I like it as I finally cum all over the floor and myself, then crawl back to the bed, obviously loving it.
After that, silence. I wait for another set of instructions, another picture, anything, but it doesn't come for over a week. Then, finally, a single sheet of paper with an address and time. On the back of the sheet, written in red ink, "Bring your collar."
