Maria Jade had so much fun using her laughing gas & masturbating the last time, that she's been doing it on a regular basis. She sits down on the floor, and places the mask over her face & takes in a deep breath. Her eyes go bright as the nitrous oxide courses through her & she gives a big toothy grin. She rubs her tits, and takes another breath, this one deeper. Now she's really beginning to feel the effects of the gas. She takes a few more big inhales, and rubs her body a little more ferociously. Soon, she's stripped out of her clothes with the mask strapped to her face & masturbating to full orgasm.
