My wife has a very beautiful sister who just came from the countryside. She has a curvy body, big breasts and a firm butt. I was captivated from the first time we met. Perhaps Niimura Akari still doesn't have a lover because during my time here I accidentally saw her masturbating many times. Even though she is married, standing in front of such a tender body like that I couldn't help but feel lustful while she was masturbating. I rushed in, caught her in the act, and threatened her to indulge me or else I would tell this story to many others. Even though Even though she was scared and knew it was against morality, due to the threat and still in heat, she agreed immediately.
