Yuki Itano's stepson, Wataru, had been acting strangely lately. He started taking my panties while I was in the bath, suddenly hugging me tightly—his behavior had clearly changed. I could sense that he no longer saw me as just a mother, but as a woman. Perhaps the stress of his college entrance exams was getting to him, and I myself couldn't suppress my own pent-up desires any longer. Without telling my husband, we began a secret affair. Now, even when my husband is nearby, we continue to indulge in passionate sex, barely able to restrain ourselves.
