Shota's mother runs a yoga school. Due to the recent yoga boom, it seems that female office workers often go there on their way home from work. Among them, Ms. Sana is exceptionally beautiful and has a big butt. Shota, who has his eyes on her, uses his position as a son of a school manager and does whatever he wants. He does all kinds of mischief, such as looking into the 'sheer buttocks' wrapped in yoga clothes and touching the buttocks in the name of a lesson. He changed into an OL outfit for lessons, took a bath together, and asked, ``Does that have anything to do with yoga?'' It is a must-see for Sana, an S-class beauty, to be raped by her cousin.
