Detroit's underground comes alive as couples explore their wildest fantasies in a game of head-based challenges. Tongues twist and turn, lips stretch wide, as the game master calls out increasingly naughty dares. The room fills with the sound of wet, sloppy kisses and gagging moans, the scent of sex and sweat mingling with the faint taste of beer. As the night wears on, boundaries blur and inhibitions shatter, leaving only the raw, primal desire that binds these couples together.
