My childhood friend Hina. She transferred from Hiroshima and we grew up living next door to each other. Smart, beautiful, and elegant—she was the girl everyone admired from afar. But one day, Hina's parents suddenly disappeared. Since then, she's been working as my family's personal maid. One day, I caught her masturbating with my underwear. From that moment on, she began seducing me every day, teasing and tempting me relentlessly. Then one day, during her ovulation period, she pleads with me to make a baby while giving me an erotic service. What will become of me?
