I heard the sound of a bucket and the order to raise my butt. Then the order to descend again. I yelped at the cold embrace of icy water and the knocking of ice cubes on my engorged genitals. I felt the way a red-hot glowing iron must feel when it is being plunged in a mountain of snow.
The sensation quickly turned to pain, as if ropes were strangling that part of my anatomy, harder and harder. My breathing became shallow and I felt tears raising to my eyes, but I got comfort in the fact that the orgasm was reeling away to a distant corner of my brain.
