My slave can't satisfy me in bed anymore and tries to make excuses for his lack of a performance.

I proceed to grab his nuts from right under his towel and squeeze them while I lecture him on how hard he's about to get his balls busted. I kick knee punch and slap his little nuts furiously so that he learns to not piss me off again. While he's on the floor he worships my cute little feet and begs me to stop kicking him in his balls. I get a few more off before standing triumphantly on top of him :)
