I never considered myself attractive, but after three years of dating the kind-hearted Mari, I started thinking seriously about marriage. One day, I joined her family on a hot spring trip and met her mother, Naho, for the first time. As someone who prefers older women, I instantly fell for her—she was my ideal type. But she was already married and a mother, and from the moment we met, I knew my feelings were hopeless, forcing me into heartbreak. Confused and shaken, I went alone to the hot spring, only to find Naho already bathing. Despite knowing it was wrong, I couldn't resist touching her beautiful, wet body. This moment of impulse and inner conflict marks the beginning of a deeper, more intense story.
