Recently, my wife, who is addicted to dieting, was stretching after watching a certain video. The female trainer on the video posting site is a slender beauty named Himari, who apparently runs a personal gym in Tokyo. A few days later, I went to Himari's gym with her wife. During the training, I couldn't control my heartbeat because of the strangely close distance and my toned body. At that time, Himari asked me if I would like to take a one-on-one lesson without telling her wife.
