We’re working together in the lab when I come in with my latex dress on and put on my gas mask. I notice you watching me and I tease you a little about how you must like girls in latex with gas masks, but I like it too. I shine up the front of my latex outfit, focusing on my breasts. You let me know how much you like it and I offer to give you a handjob. I start stroking you, but soon after an alarm goes off signaling that there’s been a chemical leak in the lab. I’m safe because I have my mask on…but you’re not. And there’s no extra masks. I think fast and grab an anesthesia mask and tell you to breathe into that, it’ll help you. After instructing you to take deep breaths, I start stroking you again and admit that I know this leak is so bad that even breathing in the small amount you did means you’re going to meet your end. I gave you the mask and gas to help make you feel better as you live your last moments. I want to give you pleasure in that time, too, so I continue the handjob, encouraging you to cum for me and give into your final moment of pleasure.
