The chick is used to being treated this way. The impotent husband lost her at cards. That's why they've been pulling her like a bitch all day long. And the harder the stake, the harder they drive it inside. Only the pussy is already so used to the new masters, to the abundance of milk - that she does not want to go back.
The chick's ass is doing a twerking, but the male offers to take it in her mouth. Well, the bitch can do that too. Fulfilling his desire and licking cum off her lips offers to use her body. What a helpful and lustful pussy.
