At the suggestion of Kana, a classmate's mother, Ichiro is able to go on a trip with two mother-child pairs. Ichiro's heart throbs because he admired Nakana, who was by far the most beautiful woman in the class. When they arrive at the ryokan, the four of them enter a hot spring, where Ichiro thoroughly enjoys Kana's long-awaited nakedness. That night, Ichiro hides in the futon while he is asleep and tries to do something about it. Her mother Ayano finds out about the affair between the two, and Tokana becomes jealous and scrambles for Ichiro's dick... Ichiro's mother was very busy with her mother who was in full bloom due to her travels.
