Shiori lives at her parents' house in the countryside and spends her days without stimulation. I was interested in H things and was in agony with information and videos on the Internet. One day, for the first time in a long time, my sister and her husband returned home, and the house was already crowded. That night, Shiori sees her sister's husband's who got drunk after a family meal. Even though I didn't have an erection, I was shocked by the splendid size. After that, Shiori's head is already full of her brother-in-law's, and she finally sneaks into the room where her sister and her husband are sleeping.
