TKFC-088 Beautiful sister exposes lewd behavior in front

[From my master] When my wife’s sister and her husband passed away, I took them in. My wife was a masochist. I had been training my wife as a slave, but she passed away a few years ago. Soon after Mari and Yuta started living together, I found out about the ○○○ relationship between the two siblings. Although they are not directly related by blood, they are my wife’s niece and nephew. As masochists, they were not satisfied with just having a horrible sexual relationship and blamed each other. After learning their secret, I was unable to stop my S-preferences from rising, and that is how it is today. Both of them are university students. I think Mari is a very beautiful girl. She is a reliable person due to her circumstances. Yuta is a clumsy sportsman with a strong siscon. And they are both masochists. My wife’s family may be a masochist bloodline. Together with my bad friends, I recorded the whole story of how I humiliated the greedy masochist siblings on video. I hope that all fans will enjoy it..
