Sexual Research

Mia steps into the locked room expecting a stipend and lab coats. The doctor hits the bolt behind her. One hard shove and her shirt splits open down the middle. He peels the rest off in quick, mean tugs, tosses it aside, then snaps cuffs on her wrists and jerks her forward until her knees hit the floor. His cock shoves past her lips, deep, no pause, and her throat tightens around it. When he yanks her up and bends her over the padded bench, he drives straight into her pussy, fucking her with hard, short strokes that slap skin on skin. He flips her again, spreads her cheeks, and works into her ass without warning. Mia’s yelp cuts off when he slams in balls-deep and stays there. The cuffs bite, the bench creaks, and he keeps pounding until her hole stretches and sucks around him. With her wrists hooked to a spreader bar above, legs wide, her big tits get wrapped in rope so tight the nipples stand out hard. Clamps bite down next, sharp and sudden. A gag goes between her teeth, drool slicking her chin. The doctor switches between her cunt and ass in long, brutal thrusts while a vibrator presses to her clit. Her body jerks, fights the ropes, then locks up hard as the orgasm crashes through her. He doesn’t slow down. Another position puts her on her side, one knee yanked to her chest. He uses every hole in turn—mouth, pussy, ass—fucking each until it’s swollen and shiny. When he rolls her onto her back, arms pinned under her breasts, the ropes push those tits up high and proud. He stands over her head, feeds his cock between her lips upside-down, and fucks her throat until his cum streaks across her cheeks, lips, and lashes.
