JUQ-186 Lustful husband has an affair with his wife's PT

Recently, my wife, who is addicted to dieting, tensed her muscles after watching a certain video. The female trainer on the video posting site is a slim beauty named Himari, who appears to run a personal gym in Tokyo. A few days later, my wife and I went to Himari's gym. During practice, I couldn't control my heart rate because of the close distance and my toned body. At that time, Himari asked me if I wanted to study one-on-one without telling my wife.
