A married woman who has been married for 6 years and works as a swimming instructor at a fitness gym. I've been working part-time at a gym since I was a student and married a salaried man who was going to the gym at the time. My husband, who is 8 years older than me, stopped going to the gym after getting married, and now my attractiveness as a man has decreased. The couple's work has also decreased sharply. When I saw a muscular man at work, I got horny and masturbated in the gym's toilet. Still, I couldn't control my sexual desire and jumped into AV.
