I'm about to go to college, so I'm going to live with my brother. I met my sister-in-law Aki for the first time, and she was very beautiful. Just as I was getting excited about our new life together, she suddenly started to seduce me... I ended up having raw creampie sex with her because of her sex appeal and beauty. After that, she would often seduce me while studying or in the bath, and we ended up having raw creampie sex many times...
