"Mayu" who lives with her husband's parents. Coincidentally, her father-in-law was her teacher when she was in ● school. During her student days, Mayu, who had more than respect for her father-in-law, devotedly cared for her. Mayu literally stretches her body to care for her weakened father-in-law. Before she knew it, her longing for her "sensei" made Mayu's body hot, and she fell into a pleasure she had never felt before.
