Big Step-Mama Muscle is back training her new pet on how to worship her big bountiful biceps. The nervous pet is intimidated with every flex knowing if he doesn't perform, she will use her biceps on him. She orders him to kiss, feel, massage her biceps. trembling and scared, he slowly kisses and massages her flexing mountains of muscle. She orders him to stand up and shows him the strength of her biceps by coiling her biceps around his waist and ribs and tightening her grip in a bearhug.
