Karen seems like a quiet, plain coworker who always wears the same tracksuit and makes mistakes on the job, but drinks reveal her completely different side. After work she pins her senior down, straddles him, and smothers him in relentless, drool-soaked tongue kisses. She pounds him in cowgirl until he creampies her, then keeps riding and kissing even after he begs her to stop, draining him again and again until morning.
