Merciless testicle flogging

I'm with my friend Mistresses, we have this slave with us who, as soon as he sees us coming, starts getting excited with his very little dick. Imprisoned and restrained Today we have some bad intentions about him, we want to have fun with his small cock. We want to make him suffer even more and he will sacrifice his balls for our amusement. Restrained and exposed for Us we want to flogg his genitals badly... more and more...
