A runaway girl begins staying at a man's house after meeting him by chance. Understanding his ulterior motives, she still allows him to use her body in exchange for shelter and pocket money. She then invites her runaway friend to join them, and the friend also succumbs to temptation, surrendering herself to the man. Watching the relationships between the other girls and the man, she gradually becomes desensitized, and the acts in the room grow increasingly intense and depraved. The encounters involving multiple runaway girls become deeper and more passionate, escalating into hardcore, fetishistic pleasures.
