I remove my slave's cock cage and tell him that I'm going to give him a very short period of time to orgasm, and then he's going back in the cage. He is excited.. But fails to realize that after months in the cage, he's over-sensitive to my ministrations. I know, of course, and decide that it will be great fun to watch him struggle to orgasm. I begin to stroke and tease his cock, taking my hands off every few strokes and making him hump the air in a degrading fashion. His cock becomes more engorged and he begins to shake.. I know he won't be able to cum so I make it harder and harder. I stroke him relentlessly, making him cry and cry, with no satisfaction. Then I smile as the cage goes back on for another 3 months..
