Starting off in a tight bikini top, I put my military style gas mask on as tight as I can fit it, I work myself up, breathing hard the entire clip rubbing my pussy and playing with my breasts until I remove my top. I cover one filter, causing me to breath louder and harder and it feels so good that I cover both filters at the same time. It feels euphoric! The way my green eyes look thru the mask are an added bonus :)
