Manita Nozomi is an ordinary student. She, prone to competition and unwilling to lose, was once brought into the world of Enjo Kosai by a friend... Enjo Kosai... To an ordinary student, this world seems far away. However! Ordinary student Manita Nozomi, through a chance encounter, was pulled into this strange world by her friend! At first it was curiosity and the need for pocket money, but gradually she discovered a unique pleasure and sense of fulfillment in this world. To prove her worth (perhaps more for the sake of pleasure) and earn more pocket money, Manita Nozomi decided to put herself out there, constantly challenging herself, and eventually became the number one ranked enco-sex intercourse queen!
However, this path was not an easy one. To become an enko queen, you have to accept everyone, whether it's a work uncle, a lusty boyfriend, or even.... father?!?
