The professor's office is dim, the air thick with tension. Two shaven pussies, belonging to his naughtiest students, await their punishment. He circles them, his gaze intense, before ordering them to touch themselves. They comply, fingers slipping into wet folds, moans filling the room. He watches, his cock hard, then steps forward, his belt buckle clinking. 'You've been bad girls,' he growls, tracing the leather across their asses. They whimper, eager, as he begins to spank, the sound of flesh meeting flesh echoing. After each strike, he orders them to lick each other, their tongues meeting in a dance of desperation and desire.
