Atsushi falls in love with his best friend's mother, Shiori. He often went to her best friend's house and was thrilled to see her, but gradually he wasn't satisfied with just looking at her face. At that time, he ends up having Kina teach yoga for some reason. Two bodies in close contact. A nice butt sticking out in front of me... Atsushi, who was aroused by the indecent yoga poses, still endured that he could not touch his best friend's mother.
