While my wife and I were bored, I was seduced by Yuki (my sister-in-law) and ended up ejaculating over and over again... Yuki Takeuchi

My wife went on a trip alone - as their relationship began to cool down, she became unable to resist the temptations of her younger sister, Yuki... ``Anyway, my sister...she's having an affair while I'm on a trip...'' The more I think it's no good, the more my sanity is blown away... Evening, night, and morning, while my wife was away, I had intense sex with Yuki and ejaculated over and over again... The immorality felt too good...
