Juan Largo, the authoritarian principal, sits at his desk, his eyes scanning the rules he's about to enforce. A knock interrupts him, and in walks Sub Girl, her eyes downcast, but her body language screams defiance. She's here for her punishment, but she's not backing down. He tells her to bend over the desk, her skirt hiking up, revealing her ass. He runs his hands over it, feeling her tremble. He spanks her, his palm leaving a red mark. She gasps, her body tensing. He unzips, his cock hard, ready. He pushes into her, his hands gripping her hips. She moans, her body betraying her, her pussy clenching around him. He fucks her hard, his desk slamming against the wall, her cries of pleasure echoing in the silent office.
