Mirei lived with her husband and father-in-law. Mirei inadvertently cut her finger while cooking one day. My father-in-law asked if it was okay and gently licked Mirei's broken fingertips. The next day, when my husband left, my father-in-law licked his finger again, wondering if it was okay. Then, the days when my father-in-law licked my fingers almost every day began. Mirei missed the timing to stop. The act of licking my father-in-law gradually escalated. One day, when Mirei was working in yoga, her father-in-law appeared and started reading a book. Mirei continues yoga without worrying about it. My father-in-law is looking at Mirei sweating with a grin. Then my father-in-law began to lick his toes as he approached Mirei. Mirei hates it, but her father-in-law licks it regardless. And she began to lick her whole body to taste the sweaty Mirei, and Mirei was gradually attacked by pleasure.
