Friday afternoon arrived. I waited until everybody else had gone, then strode into John's office. "On your feet!" I ordered crisply.

He obeyed smartly. I looked him up and down for a few seconds: "You've got one minute to strip naked!" He blushed, saw that I meant it, and began removing his clothes. His body, as he bared it to my gaze, was tanned and muscular, and his excitement was obvious in the hardness of his handsome prick.

"Now your wrists together." I snapped a pair of steel handcuffs on his wrists, and standing on the desk behind him, tied the attached cord to the solid light fitting in the ceiling.

The initial moment was over. My prisoner was helpless, his naked torso stretched taut and totally available to me. I must confess I gloated a little as I took the incriminating documents out of my purse and showed them to him. He grinned ruefully, but gave no sign of anger - he was a true submissive, I decided, and was really enjoying himself hugely!

For about ten minutes I lectured my captive, telling him precisely what I expected of him and giving him some idea of what would happen to him. At last I said: "I'll leave you for a while to think it over. When I come back, you'll have just one opportunity to call this off... but if you don't take it, you're mine for the weekend!"

I went out and checked that we were alone in the building, taking the precaution of locking a few strategic doors. Then I took a few papers to my car in the basement and returned with some other items of equipment.

Not a word was said. I simply held a large rubber ball-gag in front of John's face and paused for a moment. He looked me in the eye - and obediently opened his mouth wide! Next I padlocked leather cuffs, joined by an 18-inch chain, on his ankles and fitted a metal cock-ring firmly about the base of his still rampant prick. Untying the cord from the ceiling and refastening his wrists behind him, I passed the cord between his legs, through the cock-ring and back to knot it firmly between his cuffed wrists.

Finally I packed his clothes into an overnight bag, clipped a dog leash to the front of the cock-ring, and with a little tug led my slave out of the room.

I could see the shock on his face as he realised I was taking him, stark naked and shackled, where someone might see. "Exciting, isn't it?" I murmured, "What if the boss comes?" His reply was a stifled gurgle behind the gag.
