You and your hot, 40 something coworker have started a fling together and have begun hooking up at work. You invite her to the break room where you both plan to fuck wearing your Zodiac NBC hazmat suits. Sierra comes, horny and excited to fuck you. You see, she's modified her suit to accept your rubber sheathed penis as she rides you, fully protected behind her gas mask and heavy rubber gloves. If the plant experiences a gas leak, you both would be fully protected while having passionate sex. She incorporates her vibrator, using it on your cock and her clit before incorporating before having you each cover up your masks' filters to intensify the orgasm. The experience culminates in an orgasm countdown where you both beautifully cum together as the lovers you are.
