My uncle passed away in a traffic accident three years ago. This summer vacation, I visited a remote mountain house where my aunt Yukine lives, accompanied by my father. Seeing Yukine again after so long, she seemed just the same as before, yet somehow more beautiful than I remembered. That evening, I couldn't take my eyes off her large breasts glistening in the sunset, glowing brightly against the fading light. Later that night, I accidentally witnessed an unexpected scene—my aunt Yukine and my father passionately entwined, drenched in sweat, desperately craving each other.
