Stuck working overtime, a man thinks everyone has gone home until office beauty Mai Sasaki appears with a smile and offers him a massage. She starts at his shoulders, but her hands soon wander as she asks him to speak to the department head about a promotion. Even after he agrees, she grabs his cock and begs to lick it, revealing an astonishingly dirty tongue. Her innocent office image collapses, and the excited man decides to fuck the shamelessly horny coworker as hard and as long as he can.
