ATID-557 My sister-in-law is my old crush

Yuki returns to her hometown after many years of living in Tokyo. This is the place where he was born and raised, containing happy and sad memories, and especially memories of Yuki's sister-in-law. As children, he and Shizuka were extremely close. Because Shizuka is an only child and older, she always sees him as a younger brother. Every time we go anywhere, people treat the two of them like sisters. That made Shizuka very happy, but Yuki didn't want that. He wanted to be Shizuka's younger brother and wanted to be her man! But Shizuka fell in love with Yuki's second brother and got married. Because she wanted to forget everything, Yuki left her hometown and moved to Tokyo. But when he returned, previous memories appeared in his mind. Shizuka is still the same, even more beautiful than before. They warmly welcomed Yuki, prepared delicious food, and asked about his life situation. That night, while going out for a drink, Yuki accidentally discovered that his sister-in-law wanted to have sex with his second brother, but his second brother firmly refused so he could admire the entire scene of his sister-in-law masturbating. Knowing that Shizuka was not satisfied, suddenly the desire to possess Shizuka emerged in his mind. The next morning, while his brother went to work, Yuki invaded Shizuka's body! Shizuka also knew Yuki's feelings for her but it was too late. She loves her husband and her husband also loves her. However, she cannot deny Yuki's feelings for her. During their stay here, the two continued to secretly fuck each other. When sending Yuki off, Shizuka wanted to know when he would return to this place, but Yuki knew that he would only hinder the happiness of the girl he loved. In order to truly forget Shizuka, he would never return to this place...
