The drive home from campus was tense, Emily's thighs pressed together in the passenger seat of Professor Harlan's sleek black sedan. The vibrating butt plug still hummed faintly inside her ass, a constant reminder of the denied orgasm from class. Her pussy throbbed with unmet need, juices soaking the seat beneath her. Harlan's hands gripped the wheel tightly, his jaw set, eyes forward. 'You were very naughty today, Emily,' he said finally, voice low and stern. 'Exposing yourself like that. You need punishment.'

She nodded, biting her lip, a mix of fear and excitement churning in her belly. They pulled into his driveway, the modern house quiet and isolated. Inside, he led her straight to the living room, the spacious area with its leather couch and large windows overlooking the garden. 'Bend over the arm of the couch,' he commanded, rolling up his sleeves. Emily obeyed, hiking her skirt up to bare her ass, the plug's base visible between her cheeks. She braced her hands on the cushions, heart pounding.
