Ball Boxing and Stretching Torment

I put on my boxing gloves to practice my punches on its dick and balls. (it's part of this self defense class that i'm taking) despite the obvious pain i'm inflicting, its important for me to feel safe with a loser out of chastity. (you can never trust a beta that doesn't have a chastity cage on) its quite exhausting punching balls over and over again as hard as i can. i take a break from punching its balls into oblivion and prepare this slave for a ball stretching competition by tying weights to its nuts! (this year is a $50 gift card to the cheese cake factory) i monitor this loser's balls as i add weight. i continuously yank and pull on the rope.... stretching its balls further and further! and just when this loser thinks it's balls can't take anymore, i start punching them again! hahaha this pathetic loser is perfect for multi-tasking cbt
