At some point, my husband, who was in good health, got sick and couldn't hold his wife Tomomi. At home, there was a younger brother who did whatever he wanted to his sister-in-law's body, neglecting his older brother who was always stuck in the toilet. My younger brother, who had seen a somewhat sexually uninhibited couple up close, was delusional when he saw the sex life of such a couple. One day, my younger brother encounters a brother-in-law who is immersed in masturbation. And I took a picture of the beautiful sister-in-law's climax with a mobile phone camera.
