Caught Masturbating in My Office

I was at work, alone in my office during lunch break. I couldn't resist the urge to jerk off under my desk with a small vibrator I kept hidden there. The moment I slipped it in and started moving, the door creaked open, my boss walked in unexpectedly. Caught red-handed, or rather, red-pantied, she froze for a second before closing the door silently. Still gripping my vibrator tightly, I climaxed loudly while staring at her through the glass window. She left without saying a word.
