My husband was all ready for one of my famous footjobs, he is on his back naked with his dick so ready for my feet to stroke him off. But he is in for a big disappointing and painful surprise. I checked his phone and saw he was watching porn of other women again, something I told him not to do anymore. 
So instead of the hot footjob stroking his dick up and down I am instead going to use my big strong size 10 feet to CBT his cock and balls, but mostly his sensitive balls.
I use my long strong toes to grip and stretch his ballsack and kick them while he moans and I tell him I am teaching him a lesson he won't ever forget.
