River Lynn, a budding porn star, auditions for the role of Dairy Diva, a milk-fetish themed porn. Her stepbrother, Jay Romero, helps her prepare, pouring milk over her lingerie-clad body. River, feeling naughty, licks the milk off her fingers, her eyes locked with Jay's. She confesses her desire to be famous, any means necessary. Jay, turned on, guides her through an oral sex scene, making her moan and squirt milk. The shoot ends with River covered in milk, her newfound fame just a cumshot away.
