Because my sister and her husband decided to go on a trip alone, I returned home after a long time to take care of my nieces. The two sisters, whom I hadn't seen in a while, had gradually matured, yet they still clung to me just as affectionately as before, which put me at ease. For someone like me who's never been popular with girls, their innocent affection felt refreshing and made me genuinely happy. With few other forms of entertainment in the countryside and naturally curious kids, it was just me and my two young nieces at home—two girls and one guy. We'd always been close since childhood, and now they kept snuggling up to me, acting sweet, and drawing nearer each day. Surrounded by these affectionate niece sisters, how long could I possibly hold onto my self-control? Over the course of three days, taking advantage of the parents' absence, we indulged in forbidden, erotic relations. Those three days became a special, unforgettable time—for me, and for my nieces.
