When I was still a student, my older brother brought Sister Aika home to introduce her to the family. Sister Aika is an extremely 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 the sounds of the two having sex in the next room made it very difficult for me to control my arousal. Some time later, Sister Aika is now my sister-in-law, and I have graduated and started working. This time, on a business trip to Tokyo, my older brother invited me to stay at his place for a few days to avoid having to rent a hotel. So after many years, I finally got to meet Sister Aika again. She is still as cute and beautiful as ever. However... she wasn't wearing a bra! I could see her nipples poking out and the round shape of her breasts! Especially when I found out that my brother was working overtime and not having sex with her, I couldn't bear it anymore! I couldn't let such an attractive body go to waste! At first, she resisted, but after realizing the affection and pleasure that my penis brought, she began to actively participate with me. And so, during the time I stayed here, I took care of my beautiful sister-in-law instead of my brother...
