Koji, who had to stay out for several days due to a burst water pipe in his house, was asked to stay at his friend Ichiro's house. Koji, who secretly has an ass fetish, secretly feels the joy of spending time with Ichiro's wife, Yuu. Then, by chance, I witnessed Yu sticking out her buttocks in sexy underwear. Yu asks Koji, who has an erection due to excitement, to apply her beauty oil with her smile.
