An AV director, Takahashi Koichi, invites his wife's female friend Mitsue, 30, a married woman who runs an orchard, to stay at his place while the wife is away. The two end up alone after a misunderstanding, and over yakiniku she mentions her husband's premature ejaculation, which leads Takahashi to teach her how to improve it, then to sex, including a vibrator session, and in the morning the wife wakes up and teases him for more.
