A nerdy high schooler, her uniform buttoned up to her neck, finds herself in detention with her teacher, a rugged man with a secret hunger for forbidden fruit. He watches her innocent fidgeting, her petite frame squirming in her seat. 'You're a good girl, aren't you?' he asks, his voice low. She nods, her cheeks flushing pink. He stands, his massive cock straining against his pants. 'But you want to be bad, don't you?' She bites her lip, her eyes wide. He unzips, revealing his throbbing cock. 'Touch it,' he commands. Her small hand wraps around his shaft, her breath hitching as she feels his heat. He grabs her wrist, guiding her strokes, teaching her the rhythm he likes. She's a quick learner, her innocent eyes never leaving his as she brings him to orgasm, his hot cum spurting onto her uniform, staining her innocence.
