Ballbusting and ruined orgasm to this slave

Description: I use this slave to kick his balls which he likes so much. i tease him with my body while his cock gets hard and i decide to tie his cock so i can give some good kicks to his balls and knee strikes. then i let him go and tell him to lie down. he doesn't expect that he wants to touch himself. i order him to touch himself but i'm not going to let him cum. i'm going to ruin his orgasm.
