Young office worker Takuya is pulling an all-night overtime shift in the office. In the quiet, empty space, the sound of his keyboard typing echoes through the room. Taking a short break between tasks, he begins to feel restless as time ticks by—his crotch gradually growing tense with arousal. With no one around, he resolves to start masturbating. In the silent office, the wet sounds of his cock and Takuya's heavy breathing now replace the earlier keyboard clicks, spreading through the room like his desire enveloping the entire workspace.
