Miko Tanaka, 22, from Gunma Prefecture. Born as the second daughter of a souvenir shop owner in a hot spring resort. Her family consists of her father, mother, older sister, grandfather, grandmother, and a dog. She first masturbated in a kotatsu when she was in junior high school. She was self-employed and her family was always at home, so even if she dated a boy, she couldn't invite him to her room. When she was 19 and living alone at junior college, she was held by a man for the first time. It felt so good that she cried. She was just happy.
