Takashi, who wasn't taken anywhere during the summer vacation, decided to go on a hot spring trip with two mothers and children at the invitation of his mother, Miki's friend, Yui. In fact, Takashi has longed for his beauty and glamor body since he saw Yui during class visits. Upon arriving at the inn, the four of us went to a mixed bathing hot spring. Takashi secretly erects in the erotic body of Yui who sees it for the first time. Takashi, who can't stop Musmus, gives a fellatio to Yui who has become liberating. And Miki who was watching it also caught fire, and two moms were fighting for Ji Po! Takashi was able to enjoy a naughty trip with his two moms.
