Cage Fucking

Mistress Lexi has her slave in quite a predicament - in a cage, with his balls tied to the top of the cage. With every thrust his balls get tugged by the rope. Lexi makes the slave beg for her cock as she is ass pounding him. She begins stroking his cock until it is rock hard, and he is begging to cum. But Lexi ruins his orgasm by barely touching the cock and squeezing his bound balls, making him cum from the prostate pounding.
