I returned home after a long time because my sister and her husband wanted to go on a private trip, so I agreed to look after my nieces while they were away. When I saw my two young nieces again, they seemed slightly more mature, but they still warmly clung to me just like before. For someone like me who's never been popular with women, their affection felt refreshing and truly heartwarming. Kids in the countryside often have little entertainment, and perhaps that makes them more curious about sex. With only the three of us at home—two girls and me, the only man—the atmosphere slowly began to shift. We've always been close since they were little, and even now they naturally gravitate toward me. How long could I possibly resist their innocent charm? Over the course of those three days, with their parents gone, our relationship gradually turned intimate. It was a fleeting yet intense time where the girls' pure emotions intertwined with my uncontrollable desires.
