My wife has a very beautiful younger sister who just came from the countryside. She has a smooth body, big breasts and a firm butt. I was captivated from the first time I met her.

Perhaps Niimura Akari still doesn't have a lover because during the time I was here, I accidentally saw her masturbating many times.

Even though I already had a wife, standing in front of such a young and supple body, I couldn't help but have a desire. While she was masturbating, I rushed in and caught her red-handed and threatened her to indulge me or I would tell many other people about this.

Although she was scared and knew it was against morality, but under the threat and still in heat, she immediately agreed.
