Mistress Sidonia is conducting an expert CBT session on her bondage slave. She attaches a custom weighted ball stretcher and warms up the cock with a whipping. Once the endorphins are flowing she takes it up a level, bands are tightly wrapped around the shaft, the urethra stretched wide and electrical pads charge through his cock. Mistress has other ingenious CBT torments in store and loves the control she has over her slave.
