Yes Mistress, Thank You Mistress!

Mistress Ariel and Mistress Amanda are whipping their slave's bare back with their vicious bullwhip, like they never want to stop. They take turns and that way they can save more energy for the backwhipping. The slave suffers like hell, but he doesn't dare to complain, he says: Yes Mistress, thank you Mistress! whenever one of his sexy dominatrix whips his back.
