A submissive male, self-conscious about his small penis, seeks training from a stern dominatrix. She begins by humiliating him, laughing at his tiny cock and comparing it to a clit. She orders him to crawl, calling him her "little worm." She then ties him up, suspending him from the ceiling, and teases him with a large dildo, rubbing it against his face and making him worship it. Throughout the session, she maintains a humiliating dialogue, degrading him while he whimpers and begs for her approval.
