Yura is a housewife who lives with a silent and serious husband. Her husband has always been a bland person, and her daily and night life have become unexciting. Recently, she has become friendly with the wife next door, and they have been having dinner parties together. Her husband and the husband seem to get along well, and the couple have been getting along well. One day, while she is having tea with her wife, the husband comes home. When the doorbell rings and the wife leaves the table, the husband suddenly kisses her. Yura, who has never had any excitement in her daily life, is confused, but she doesn't feel bad. However, because it's awkward, she wants to keep her distance from the couple next door as much as possible. One day, her husband says he's going to have a dinner party with the neighbors, and Yura can't refuse and joins in. They drink alcohol and the dinner party progresses. Then the husband and wife get drunk. As if he'd been waiting for them to get drunk, the husband embraces Yura and gives her a passionate kiss. Then when the husband shows her his hard, erect crotch, Yura becomes so excited that she sucks it as if she's tasting it. And she had repeatedly reached climax through sexual acts that she could never experience with her husband...
