Rei takatsuki - 我想要我的姐夫，一个画家，所以我自愿成为他的裸体模特

I have a brother-in-law who is an unsuccessful painter after graduating from art school. My husband was always tired from his work and I was frustrated because he didn't care about me. At that time, my brother-in-law asked me to be a nude model. I knew it was wrong, but I really wanted to seduce my brother-in-law. I stripped naked in front of my brother-in-law.
