'Mao' decides to attend a drawing class as a new hobby. She suddenly draws a man's nakedness, but she stares at it even though she is shy. In her second class, she does the modeling herself, but she is gradually stripped of her clothes and gradually gets wet with excitement at being seen. At the end, she becomes completely naked, and while her big tits are groped, she goes into an orgy with her teacher and all her students.
