Mistress Sidonia's slave is tied to the bondage chair, cock and balls exposed on the CBT board. She proceeds to tie them up tight and use sharp pegs to sensitise the head and then zaps it with the prod, in readiness for her special electric cock cage. This squeezes down hard and allows the Erostek to pass it's current directly into his meat, making him moan. When sufficient punishment is taken, he is rewarded by mistresses warm, soothing hand rubbing in the pain.
