Nikky French is a true sadist, so maybe not the perfect match-up with slave Kneel that is more into boot worship. Mistress Nikky will however always get it the way she wants and goes hard on slave Kneel. She starts with some sensual boot worship and then gets more a more brutal the slave to swallow her big heels. When she have had enough of boot worship, she orders the slave to the cross for a flogging.
