A rookie cop pulls over an 18-year-old girl, suspecting she's underage. She's nervous, her hands trembling as she gripping the wheel. He asks for her ID, his eyes widening at her youthful appearance. "I'm 18," she insists, but he's skeptical. "I've heard that one before," he smirks, leaning in to chat. She squirms, her cheeks flushing as he flirts, her uniform suddenly feeling too tight. "I'm not that kind of girl," she protests, but her body betrays her, her nipples hardening beneath her shirt.
