Staying after work when the power is off at home, using the work wifi to watch videos and browse. Arousal strikes, and no one else is in the office... you’re sure the doors are locked, the lights are out. A full moon outside, your mind turning to more lustful pursuits. Why not? Masturbating after hours... caught by your fox woman superior on the project, and subjected to her helpful ministrations. You might have different urges in the morning.
