A male employee falls asleep at his desk while working late alone. Cute young adult cleaner Rinka Natsume enters without realizing anyone is still there, and the sound of her cleaning wakes him. Aroused as he watches her work, he grabs her breasts and forces deep tongue kisses on her to keep her from crying out. Though startled, Rinka barely resists and gives in to his demands. Several days later, she returns for another late-night shift and finds him waiting with a sex toy. When he presses a powerful vibrator against her clit, her panties quickly become soaked.
