A young sexually explicit mother with her son's classmate.

It was winter five years ago, and I committed the sin of infidelity. At that time, Yuzuru-kun, who was unfaithful to his husband, was moved and honestly expressed his affection for me, who was injured. I wanted to fill my loneliness, and even though I knew it was wrong, I responded to that thought. A boy grew older. Every time he was asked, his flickering guilt was overshadowed by intense desire. At first, I intended to provoke my husband's anger, but my feelings for him grew deeper every day.
