FSDSS-608 Sister-in-law...

When I was still a student, my brother introduced his girlfriend, Aika, to the family. Ranran Fujii is an incredibly cute and beautiful girl, especially her big breasts that I couldn't take my eyes off! I felt jealous of my brother for having such a good girlfriend. Hearing them have sex in the next room made it very difficult for me to control my arousal. After some time, Ranran became my sister-in-law, and I graduated and started working. When I had a business trip to Tokyo, my brother invited me to stay at his house for a few days instead of renting a hotel. So after many years, I finally got to see Ranran again. She was still as cute and beautiful as ever. However... she wasn't wearing a bra! I could see her nipples poking out and the shape of her round breasts! Especially knowing that my brother was working overtime and not sleeping with her made it unbearable for me! I couldn't let such an attractive body go to waste! At first, she resisted, but after realizing her feelings and enjoying the pleasure that my cock brings, she began to actively join me. And so, during my stay here, I took care of my beautiful sister-in-law on behalf of my brother...
