Leashed balls for kicking

Mistress Brianna is in a particularly sadistic mood and wants to make sure her bitch's balls are thoroughly busted. She makes a ball leash out of some rope and forces her slut to take kick after kick. He can not get away, and with his balls securely bound, there is no where to go - and with his arms bound, no way to resist. He is totally helpless and must absorb the full force of each ball kick. Even collapsing to the ground does not mean that Brianna will stop the assault on his balls. Satisfied that they are completely busted, Brianna stands over the slut in triumph.
