JAV Tokyo

Iori is a married woman who works as an instructor at a swimming school. Her relationship with her husband has cooled down compared to when they were first married, and swimming in the pool is the only way for her to relieve stress. Then, her husband brings home a junior colleague, Sugimura, who, on his advice, decides to attend the swimming lessons. Iori, who usually teaches children, becomes aware of her husband's muscular junior swimmer as a man. Sugimura is no different. He sees Iori in a swimsuit as a woman, forgetting that she is a married woman, and crosses the line.
