"Mako", a full-time housewife, was asked by a friend from school when her husband was on a business trip, "I want you to keep my son Shota for a few days." When I went to meet her, Shota was there. In fact, Mako met Shota when he was young. The two reunite for the first time in several years, and the old story blossoms, but Shota's heart is pounding when he sees Mako's oversized breasts. Eventually, Shota, who could not control her desire, proposed to take a bath with Mako. Shota gets excited when she sees her naked woman for the first time.
