You arrive to work late at the lab, and your coworker made an excuse to the boss to cover for you. She tells you that the boss is out on one of his usual long lunches. You both get right to work on processing lab test samples. Your coworker notices you staring at her chest, as she's very obviously not wearing a bra under her tight tshirt. She calls you out and you admit it. Surprisingly, your coworker isn't upset... she starts flirting with you. She takes out her titts and teases them with her gloved hands. She encourages you to take out your hard cock and start stroking it. Don't worry, no one will even know. You have plenty of time before your boss returns to work. Your coworker begs to give you a handjob. She desperately wants to stroke your cock, and you eagerly let her. She pumps your cock until you blow your hot load all over her titts and gas mask.
