Mallory is taking a night off work to stay home & relax, but her brother is horny again. He hasn't been getting enough sex lately, and he asks if she'll get him off. Since he was able to blackmail her last time, he thinks he can get her to fuck him again, but sister has other ideas. He can pay her for sex, but it will cost him double. Reluctantly, he hands over all his money. Who could resist sister's big tits?Mallory starts off expertly sucking & deep throating her brother's cock, then giving him a titjob. They fuck, Mallory's tits flopping around wildly. She gets a little creeped out by brother looking at her, so she tells him to fuck her doggystyle. Then she lies down, wraps her tits around his cock & he titty fucks her. He loves her big breasts so much that he nearly cums all over them, but quickly pulls out & cums all over her face & neck. He's going to get his money's worth. Brother might be her biggest client from now on.
