Electric Shocks Beating and Three Ruined Orgasms

During his period of chastity, the slave committed several offenses, which will now be punished mercilessly. I sentence him to 500 lashes, to be carried out while he is suspended. Trapped helplessly in the ropes, I also attach an electrode to him and turn the electrical stimulation device up to level 30.
Then the lashes rain down on his defenseless body. The rules of the game are cruel. He is allowed to beg for mercy at any time. I grant his plea, give him a brief respite, and stimulate his cock but the catch follows immediately. For every plea for mercy, the next lashes become all the harder. Torn between sweet pleasure and inescapable pain, he fights his way through until the last ten blows push him completely to his limits.
After he's endured the 500 strokes, I remove the electrodes and devote myself intensely to his rock-hard, aroused cock. Due to his long period of abstinence, he is immediately on the verge of exploding. I drive him to the brink of climax again and again and stop him cold, until he finally slides into an extreme, ruined orgasm.
Despite the considerable amount of semen, I show no mercy, continuing to massage him relentlessly and driving him through a total of three frustratingly ruined orgasms. Completely exhausted, I let him fall to the floor, where he looks up at me gratefully, caught between gratitude and exhaustion.
