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 seems to be opening a personal gym in Tokyo. A few days later, I went to Himari's gym with my wife. During training, I couldn't suppress the excitement of my chest with a strangely close sense of distance and a toned body. At that time, Himari invited me to take a one-on-one lesson without telling my wife.
