Mistress Iside - Demolition Balls - Genital punishment

This slave' balls have already tasted my deadli kicks and, for some time, he has lost his sexual appetite and, consequently, the need to jerk-off. But, since a few days, he seems to have gone back to whom he was before: he has strange fantasies that occupy his mind and this is no good. What is required, in such a case, is a double ratio of kicks, to definitively destroy this slave's balls, so that he won't have any more strange fantasies and can concentrate on his job.
