Teasing the swollen blue balls of a slave

Description: I have full control of his cock. he has been in chastity for a week, locked in a cage. after the last beating of his private parts, they are very swollen and sore. i let him out of the cage, only for his balls to swell even more. how unpleasant it is to watch helplessly as i stroke him to orgasm over and over again. and every time he moans in pain.i sensually rub my ass against his blue balls and stroke his cock. it drives him crazy, he gets very excited, but in the end i knocked out an erection and lock back the even more swollen, blue slave eggs, for an indefinite period.
