A dominatrix, clad in a corset and stockings, takes a sadistic pleasure in humiliating her male slave for his small penis. She makes him stand naked, comparing his tiny cock to a "laughable" size, and forces him to chant "I am sorry my cock is so small" repeatedly. She uses a variety of objects, like a pencil and a small toy, to emphasize the size difference, making him feel inadequate and worthless. She then makes him worship her boots, using his tiny dick to clean them, before making him jerk off while she laughs at his futile efforts.
