At first, it was just by chance that I saw her, but from that moment on, my heart raced at the sight of her soft breasts, her fluffy peach-like buttocks, and the tightly curved waistline. Her adolescent body, though still immature, radiated a strangely pure charm. Gradually, secretly watching her bathe became the seed of growing desire. One day, our eyes met—and her response was unexpected. "I've always known you've been watching me, big brother," she said mischievously, instantly shattering my defenses. My heart pounded wildly—her wet hair, the faint scent of shampoo, her bare skin mingled with summer sweat—reason vanished completely. Overcome by a sense of taboo, I hungrily licked her body, our passion merging until we were drenched in sweat, unable to stop. Perhaps our bodies were simply compatible—her returning the favor by peeping on me during baths soon became the secret signal for forbidden sex.
