It's after hours and I'm the only one left at the medical clinic! Wearing my pink nurse's dress, glasses, and a medical mask, I sneak into my boss' office. Once safe inside, I take off the glasses and surgical mask. I know the doctor keeps a nasal cannula and gas tank of gas in his office, so my plan is to hook it up and breathe in that gas! As soon as I put on the nasal cannula and start inhaling, I get horny! To insure that I get as much of the gas as possible, I put the blue medical mask back on, over top of the nasal cannula. Then I caress my breasts and remove my dress plus the mask. Sitting on the edge of the bed, I confess that I brought a sex toy! I turn on the small vibrator and rub it against my wet pussy. For the next 8 minutes I masturbate, moaning and talking about how hot it would be if my boss walked in on me, or had a secret security camera recording me
