Once you turn your back on a slave, and he has his hand in his diaper and plays around with his tiny dick. Well, you wait little pig! For such cases, I always have my stun toy at hand. So I'm driving him through the stairwell in front of me. I love the sound when the sparks spray and the slave meat twitches. I hope that this will be his lesson and that he will not play with his cock in the future. Although, he can not come anyway, because he is of course securely locked in the chastity cage.
