In a stark, fluorescent-lit room, a teen girl learns the art of deepthroating from a seasoned lover. He teaches her to relax her throat, to breathe through her nose, as he slides his cock in and out of her mouth. She's clumsy at first, her teeth scraping his shaft, but he's patient, guiding her with gentle words and firm hands. She tries again, taking him deeper this time, her eyes widening in surprise as she feels him hit the back of her throat. He encourages her, his voice hoarse with desire, until she takes him all the way in, her nose pressing against his groin, and holds him there, swallowing around his length.
