A housewife with an athletic physique who works hard to satisfy her sexual desires is unable to resist the young and firm penis of her fitness trainer. (Sayaka Nito, SONE-442)

She said she wanted to get her indifferent husband's attention back... A sexy married woman with a full bust, slender waist, and rounded hips, recently joined the gym. She was gentle and easily manipulated... Today she was soaking wet again, sweating and swaying her breasts and hips as she diligently trained. No... To improve the training effect, I must take it seriously... But I couldn't hold back any longer. Without realizing it, I had begun to fondle her perfect, voluptuous body... Perhaps it was because of the accumulated lust from my daily life, but I directly penetrated her body, the muscles I had been training colliding, making a sound of muscle thrusting. Each time I penetrated deeply, she would let out a voluptuous panting, her excitement growing higher and higher. She kept twisting her waist, unable to stop. After finally ejaculating, I suddenly regretted it, wondering if we would ever see each other again... But she had come back to the gym to renew her contract, and her dog-like eyes were irresistible to me. We were alone in a private gym, sweating and climaxing, indulging in our lust. Without realizing it, she had become a prisoner of my penis. I guess she had forgotten the affair, even her husband. She had become an incredibly horny, perverted wife, and we kept going until she had an unbearable orgasm.
