My slave has been very naughty. Today he's going to be shown what happens to naughty little balls. I'm not going to slap them around or even tie them up. I'm going to use my steel tormenting devices to constrict, nip, squeeze, and flatten his sensitive balls. I delight in the punishment of helpless pathetic balls. Using a spiked collar and two different vices really seem to have the effect I desired - contrition.
