While Nozomi's husband, Kenta, is away on a business trip, Takada, who has just moved in next door, comes to say hello. He helps Nozomi on her way home from shopping and suggests they share a glass of wine. Nozomi refuses, but Takada forcefully invites her in, leaving them alone at home. Taking advantage of Nozomi's loneliness, Takada caresses her while her husband is on the phone and they have sex. In the shower, Nozomi regrets her betrayal, but is once again swept away by Takada's eloquent seduction. Later, Takada returns, and they share a passionate kiss before heading to the bedroom. Unable to ignore the call from her husband, Nozomi answers the phone at Takada's instruction while they are having sex. She tries to suppress her moans as they talk, but she becomes immersed in a sense of guilt and pleasure.
