Experiment gone wrong - gas mask fetish (HD MP4)

I'm working on an experiment in my lab when i get a phone notification and accidentally knock over my work! the chemicals mix together and form a potent gas that immediately triggers the lab into a security lockdown. i'm coughing and freaking out, they've locked the lab doors with me still inside. i rush to put on my gas mask, but it's too late; i can already feel the effects of this strange gas coursing through my body. it makes me feel... hot. and confused... and horny! before i can even tell what i'm doing, i start caressing my body. i frantically strip off my clothes (revealing black lacy lingerie underneath) and can't stop myself from masturbating! pulling my panties to the side and fingering my gorgeous hairy pussy, moaning with pleasure even though i'm doing all of this beyond my control. the gas mask stays on while i'm bringing myself closer and closer to orgasm, but as i reach climax, i rip the mask off and let myself reach a hard climax! the gas is too much though, and after i cum, i gasp and cough and lay down on the table.tags: american, brunette, gas mask, respirator, experiment, nurse, scientist, lab assistant, roleplay, black lingerie, role play, masturbation, solo female, solo masturbation, body control, orgasm, coughing, gasping
