Oppai no Ouja 48 Ep - Season 1

While reading an adult book recently, the protagonist privately wondered if he could identify individuals solely by their breasts, musing that this might make him a 'king of oppai.' Lacking any method to test this notion, he considered it a mere fantasy. His situation changes when he receives a letter containing numerous complimentary sex tickets. Each ticket bears a photograph of a woman's breasts on its reverse side. As he puzzles over this, a girl named Nil appears before him. She explains that the tickets are genuine and that he has qualified to participate in a game. His assigned mission is to locate and match each ticket with the woman whose breasts are pictured on it. Thus begins his dedicated search.
