My father's remarried mother-in-law, Miku, was a woman who was closer in age to Kazuhiko than my father. Although there was a slight repulsion, he felt attracted to Miku's beauty. While deepening his relationship with Miku as a parent and child, Kazuhiko accidentally sees the relationship between his father and Miku. A sight too exciting for a virgin. Kazuhiko goes out of control and begs Miku to have sex... from there, their forbidden relationship begins...
