Miki is a fitness instructor who draws attention for her beauty and skill—an unconventional mistress known for challenging not only her students' bodies but their minds as well. Today, she once again subjects the men brought by her personal slave to intense treatment. During abdominal training, she adds thrilling intensity by dripping hot wax, and under the guise of measuring lung capacity, she performs face sitting. Yet, the sight of men enduring this suffering, desperately seeking the drink bestowed by the Dominatrix, captivates all who watch. Each richly charged moment deepens the story further.
