A dominant mistress trains her cuckold husband to serve her every need, including satisfying her insatiable appetite for big black cock. She brings home a rotating cast of black strangers, each one bigger and more hung than the last. The cuckold is forced to watch, helpless, as his wife is filled and stretched to her limit, her screams of pleasure filling the room. After each session, the cuckold is made to clean his wife's cock-filled pussy, licking up the copious amounts of cum left behind, before being sent to bed, hard and unsatisfied.
