In the first chapter of their anal training, Miss M, a stern and tattooed dominatrix, introduces her new slave, P, to the intense world of anal pleasure. She commands him to worship her body, starting with her feet, before presenting his ass for her inspection. Miss M admires his chastity cage and deems him ready for his first anal experience. She begins with a large dildo, pushing it deep into his eager ass, stretching him wider with each thrust. The slave moans in pleasure and pain, his body shaking as Miss M expertly brings him to the edge of ecstasy.
