She had you tied to a bondage rack. You were on your knees, upright, legs spread. One hand was tied behind your back. The other was free. She had told you, "Stroke. Don't cum." It hadn't taken long to hit the edge, then you stopped. She immediately kicked you in the balls three times. The blinding pain helped you come down off the edge a bit, which was good because she only gave you a little bit of recovery time before she repeated, "Stroke. Don't cum." Again, once you got the edge and stopped she kicked you three times.
You lost count of how many times this went on. The kicks came closer and closer as the edges came faster and faster. Eventually, she dropped the "Don't cum" with each command and just said "Stroke" but you could tell it was still there. You began to dread reaching each edge, knowing that you would have to stop, and knowing what pain awaited you once you did. You started stroking slower and lighter, trying to make it take longer to reach the edge. She didn't seem to mind; it was playing very well into this little mindfuck she had put you in. Besides, your balls were still making cum, thinking they had a job to do, so her other goal of making your blue balls worse was still being accomplished.
Eventually, long after you were desperate for this little game to end, she said, "You can cum if you want..." Oh sweet Jesus! Not only was the game over, but she was giving you a reward! Desperate to end both the pain and the frustration, you grabbed your dick firmly and gave it the few strokes it would take to burst that long-awaited load.
You were so desperate, in fact, that you only heard the words, not the tone that said her sentence wasn't finished. You stopped stroking immediately when she said, "....but I'm going to kick your balls a hundred more times if you do." Your hand flew from your cock as though it had been burned, but it was too late. You could feel it welling. You tried, desperately, to hold it in, but it was too late. You felt it dribble out in the slow, leaking stream of a ruined orgasm. You tried to apologize, but it was too late.....
