Hikaru is the only daughter raised by her single mother, a career-oriented woman who often leaves home due to work. Feeling lonely, Hikaru started going out at night, which led to her mother finding out and arranging for a relative, an older man, to monitor her during her mother's business trips. However, this older man had long harbored intentions towards Hikaru... relentless harassment, forced oral sex, demanded M-leg masturbation, merciless creampie, a hopeless three days. Yet, despite being unwilling, Hikaru's heart and body began to awaken to pleasure.
