CBT and Tickling Under My Sadsitic Fingers

First, the slave was securely strapped to the bed, and his testicles were tightly bound so I could work everything roughly. I alternately tickled him intensely and pulled his testicles. He squirmed against it, but I prevented that by sitting on his chest, immobilizing him. Additionally, I worked his cock with my bare feet, stroking and kicking it.
