My ordeal began when I came to and found myself naked in a shower cubicle in what looked like a normal domestic bathroom. I was standing but bound individually at the wrists and ankles so that my legs were spread and my arms and hands held high and apart, forming an X. I struggled for a while, but the leather straps had been expertly tied. A ball gag had been applied to prevent me from calling for help. Hanging around my neck was a loop of string. A clothes peg hung on the string at about the level of my navel. I could hear a radio - Radio 4 I believe, and from the sound it would appear that the radio was on a lower floor; perhaps I was being held upstairs. After a while I heard the 5 short and one long 'pips' that are broadcast on the hour. Following this came footsteps up a staircase, towards me. The bathroom door began to open, and through it came a casually dressed woman carrying a stool. The woman walked up to the shower cubicle and, having placed the stool in front of me, sat down. I attempted to ask questions but my muffled cries were simply met with a 'shhh' and the information that if I didn't struggle, I might enjoy myself. The then took the clothes peg in one hand, and taking my penis in the other, clipped the peg on to my foreskin so as to lift up my penis, exposing my balls. Next, She switched on the shower and made adjustments so that the water issued from the shower head with some force, but without being anything but comfortably warm. And now began the treatment that I have since experienced many, many times. The spray from the shower head was directed on to my balls, the individual jets each feeling needle sharp as they pummeled my sac. For the first five minutes the shower head was held in one position, and by the end of this period my scrotum was feeling super-sensitive. The shower head then began to move, slowly and in small, back-and-forth movements. By now I was feeling quite aroused, and the new sensations caused by the moving jets were getting quite enjoyable and I had forgotten that I was a captive. As I became more and more erect, the movements of the shower head were slowly increased, and this in turn increased my pleasure. At no time was the water directed on to my cock - it would seem that my captor was only interested in my balls. After what seemed like an age, where the woman constantly teased by balls , I could take no more and experienced a fantastic orgasm which left me weak at the knees. Once I had ejaculated th woman switched off the shower and left the bathroom. I regained my composure, and tempted to release myself from my bonds. However, after a while, I heard the pips from the radio again, and then the footsteps approaching on the stairs. The woman appeared, clipped my penis out of the way again, switched on the shower, and repeated the procedure, firstly giving my balls a good pummeling, and then gently moving the jets around. Again I became erect, and after much coaxing with the fast flowing water on my balls, came again. I had been forced to have two orgasms and to ejaculate twice in the space of an hour. This time I did not recover quite so quickly, but would experience a 'judder', like a mini orgasm, every now and then, together with a constant but pleasant ache in the balls. Again I heard the pips, and again the woman appeared, prepared my cock, and went to work on my balls. This happened every hour on the hour. Strangely, I was always able to ejaculate, and this must have had something to do with the hypersensitive state that my scrotum and testes had been placed in by the hourly pounding from the shower. In addition, the judders began to turn in to more powerful orgasmic quakes which would occur with increasing frequency and duration between the hourly treatments. On one particular occasion, I noticed that, on hearing the pips, I began to become erect. by the time the woman appeared I was stiff and ready. I am sure I saw a smile play briefly across her lips as she saw this upon entering the room. This was the first occasion that my cock did not need to be pegged out of the way - my balls were exposed and the shower was applied directly. The orgasmic quakes continued to increase in intensity between visits from the woman, to the extent that I was beginning to spend more time experiencing them than not. The next significant stage occurred when I heard the pips from the radio and began to get stiff. This time, by the time the woman appeared, not only was I rock hard, but was oozing pre-cum. I believe the woman smiled and actually licked her lips when she saw the clear strand hanging from my cock. This time the woman seemed to take more notice of my pleasurable reactions, and watched me for a while after I had cum. She seemed to be very satisfied that the orgasmic aftershocks that I was experiencing were almost constant now. At one point she simply said in a voice mimicking that of the radio 'pip', and my knees buckled as I enjoyed another orgasm. The woman left the room smiling. I now believe that I am the subject of some bizarre experiment, the purpose of which is to induce a state of constant orgasm. Certainly in the last 24 hours I must have spent 23 hours cross-eyed as my cock throbs and spurts and dribbles. Perhaps I can endure one or two more treatments before I the orgasm becomes continuous. I can't wait.
