In the dungeon, Miss M, a dominant mistress, begins her weekly fisting session with her submissive slave, P. She starts with a massive dildo, stretching his tight asshole, then moves on to her gloved hands, pushing two, then three fingers deep into his raw, unlubricated hole. P moans in pain and pleasure as Miss M tears into his ass, using him as her personal fuck toy. She makes him lick his own ass juices off her fingers before resuming her brutal anal assault.
