The late-night cleaning crew finds more than dirt in the office; they stumble upon the HR manager and the IT guy in a passionate embrace. She's bent over her desk, her pencil skirt hiked up, revealing her round ass. He's pounding into her from behind, his hands gripping her hips. They're oblivious, lost in their own world of lust, the sound of their bodies slapping together echoing in the empty office. The crew watches, entranced, as the duo reaches a simultaneous, shuddering orgasm.
