CRB-042514-588 Asking her naked brother to draw her, her younger sister suddenly became interested and...

As a senior student at an art university with a drawing department, she was having a headache thinking about a big assignment topic so she could graduate on time, when Ruka Kanai received a very attractive suggestion. Quoted from his brother, it is nude painting and of course the nude model is also him. I thought everything would go smoothly until I started working and things went in a completely different direction. The older brother had just taken off his pants when the younger sister exclaimed in shock because of what could be said to be the biggest penis she had ever seen. Seeing big potatoes made her happy, and she wanted to experience strong feelings for once, so she made a small suggestion before starting to draw, hoping that he could meet her sexual needs, and at the same time. had an incestuous relationship with her. Even though he knew this was against morality, if he didn't accept it, his sister would refuse to paint, so he had to reluctantly comply with that lewd request.
