you slide your cock slowly up her leg as she gently spreads her legs making sure the doctor takes no notice. the doctor is passionately yammering on and on about the formula and how much of a genius he is. the lab tech nods and spreads her legs wider. as you move up her slender thigh you begin to feel the warmth of her willing womb. next you begin to feel the tickle of her short trimmed bush. then you feel the wetness of her cum soaked pussy lips and finally the touch of hot moist inner folds. you can visibly see her shudder as you push inside her deeper. of course the doctor takes no notice, in fact he isn't even looking at her anymore he is kind of looking at the ceiling recalling the day he thought up this concoction. you begin to slowly move in and out of her and notice her grab her tits. the doctor turns around as he is talking and walks across the room. the lab tech turns her head to look at you through the corner of her eyes flashing you a devilish grin and a lick of her lips. you quicken your pace and go a bit deeper with your thrusts. across the room the doctor asks "do you wanna know how i figured that out?" the lab tech squeaks meekly "yes!" the doctor continues on as you begin fucking her fully making her pussy squish and queef. she turns to you quickly trying to hush you but hoping you wont stop. the doctor finally breaks from his ego stupor hearing the noise and quickly grabs his notepad and begins writing.
