Sierra is suited up in her most chemically protective gear: her Zodiac NBC hazmat suit. She knows you like to see her wearing it and how hard your cock is. She encourages you to put your own suit on, don your own gas mask, and use your gloved hands to stroke yourself off while she jerks off her cumming dildo. Throughout all this, Sierra's vibrator is in the suit with her being controlled remotely so she can cum with you. Of course the video ends with her taking a load all over her protected body.
