Shelli, the dominant mistress, delights in her sub's discomfort. She clamps the girl's nipples tightly, a cruel smile playing on her lips as she watches her squirm. A thick gag stifles the sub's cries, her muffled protests only fueling Shelli's desire. She slaps the girl's face, leaving a red mark, before pushing her onto her back and spearing her tight pussy with a massive dildo, fucking her rough and raw until she cums hard, dripping onto the floor.
