Squeezing and Slapping Balls!

Description: Last time i squeezed my slave's balls, he was bucking a lot, so today i tied his legs to a metal tube. i really like this thing! i sat on my slave and started playing. i was squeezing his little nuts and he couldn't do anything! he tried to grab my hands, but then i squeezed his balls even tighter. sometimes i also spanked his genitals and played with his cock!
