Mistresses Alexis Grace and Macy Cartel have had their milking slave bound with his balls locked in a humbler for days, and now they want to drain every last drop of cum from his pathetic balls. The Mistresses toy with his helpless nuts, smacking them and crushing them before jerking his cock, still locked in a humbler, just to cause him pain.
When the Mistresses actually want the bitch to cum, they stand him up and remove the humbler so they can really jerk his pathetic cock. Alexis makes sure the slave cums in her hand because she is going to make sure he eats every drop. With his mouth pried open with a gag, it is not like he had any choice in the matter.
