Maki Sanjou, the daughter of a famous model, has not only inherited her mother's astonishing looks, but is also incredibly wealthy. She is immensely popular with young men and women alike, exuding the aura of a prim and proper princess. Despite Maki's perfect image, she has a tendency to masturbate in public, often imagining herself being caught, blackmailed, and forced to obey her captor's wild sexual desires.

Coincidentally, her neighbor is Seiichi Sakonji, a young writer employed in the erogames sector. One summer night, when he decides to take a break from work, he overhears Maki moaning in the veranda. Seiichi approaches cautiously, but the wall separating their balconies accidentally comes down and he is caught eavesdropping. However, Maki quickly interrupts his apologies, confessing that she secretly hoped he would come.

After Maki suggests that Seiichi coerces her into whatever he wishes, the two make love and become a couple. As they engage in various sexual activities, Seiichi cannot believe that he has found such a beautiful girlfriend, and Maki is ecstatic with a boyfriend willing to satisfy her perverted fantasies.
