It's been a long day at the ER, and Nurse Carmen is ready for a little rest & relaxation. She comes home, grabs a tiny tank from her secret stash, places the mask over her mouth & nose, and inhales as deeply as she can. Her eyes roll into the back of her head & she lets out a loud peal of laughter. She unbuttons a few buttons on her uniform, revealing her white longline bra & removes her panties. She rubs her pussy a bit while inhaling more of the sweet gas, then reaches for her hitachi. She straps the mask to her face, turns the hitachi on "high" & begins her transformation into an orgasming bimbo.
