CBT, orgasm control and ruined orgasm with the magic wand - part 1

The slave and his slave cock are challenged today properly. In midsummer temperatures, the slave is in a short black rubber coat. Today I want to play at the beginning only with his dick and his balls. He kneels on the bench and I start to take care of his "best" piece. The Dick gets very quick very hard in the hand of the mistress. The first surprise for him will be: I'll get out a very old chastity belt that another slave gave me many years ago and test it out to see if it's still complete and working. Friends of CBT with a lot of soft eroticism will get their cash worth.
