The clock strikes midnight in the office, and two curious students, locked in together, find themselves alone and bored. They start exploring each other's bodies, their hands wandering over desks and chairs. The girl, in a short skirt, teases her partner by rubbing her ass against his crotch. He responds by unbuttoning her blouse, revealing her lacy bra. They move to the desk, where he bends her over, pulling down her panties, and begins to fuck her slowly, the soft thuds of their bodies meeting in rhythm with the ticking clock.
