A spiky handjob is the only relief he deserves

My slave has been locked in chastity for a month, but today I'm going to allow him a release. I fixated him to the St. Andrew's cross, because he will only get an orgasm under special conditions... Before I let him out of the chastity cage, I tease my slave with my naked breasts. I just love seeing how his swollen cock presses painfully against the cage. As soon as the penis cage is off, I get the next lockable toy: a cock ring with nasty spikes. These spikes will make him suffer immensely, as soon as he gets an erection. Too bad my slave is so easily aroused! The fact that he hasn't cum for a month doesn't make it any better. Now I'm going to give my slave a painful handjob until he cums!
