Fighter Kicks and Punches VS Slave Balls - Preview

A fighter needs a punching bag to practice kicks and punches.
I like being that punching bag and trying to take all the guy's blows.
He kicks me in the balls with all his might, I almost cry, but I don't give up! Punch me! Kick me... I like to feel the hardness of each impact and wait for the next!
When the fighter is hairy and strong, and sweaty, it's even better!
