Sota is dating Chizuru, a beautiful girlfriend, and feels on top of the world. Before long, however, he discovers that he has been tricked into taking over his parents' debt, leaving him crushed and desperate. Chizuru, seeing no other way out, suggests they become "sextreamers" — adult streamers who broadcast intimate content online for money. Though both are inexperienced (Sota is a virgin and Chizuru a virgin as well), the couple decides to start a sexy streaming channel together to earn their way out of debt.

Their journey begins with learning the ropes of adult streaming, from hesitant first attempts to bolder experiments. Early narrative arcs include trying oral acts, shopping for adult goods, performing their first outdoor broadcast, and eventually preparing for their first full sexual experience on stream. The story follows their awkward yet determined steps as a real-life couple figuring out how to monetize their intimacy, all while navigating the emotional and practical challenges of their sudden financial crisis. The manga blends erotic comedy with the tension of two young people whose relationship is tested by the very public nature of their new enterprise.
