妻とは結婚5年目です。たまに「妻の妹」ルカちゃんが、我が家へと、遊びに来てくれたりしていて。先日の晩、私、会社の飲み会で、少々飲み過ぎて…酔って帰った勢いで、久しぶりに、寝室で寝ていた妻と、夫婦の営みの方を、頑張ってみたのですが…。翌朝二日酔いで目覚めると、妻と、「妻の妹」が、台所で仲良く並んで、朝食の支度を、していましてですね…。「さっ昨晩私が抱いたのは、妻ではなく、妻の妹だったかもしれない…」。










The beginning doesn't show her face, so it wouldn't work unless the actress could captivate with her body alone; I think it only works because of her great figure. The second half is quite nympho-focused, so it might be a hit or miss depending on your taste.
*There are some settings in S1 and others that really liven things up, but this work's excitement is one step further. In Toshiro's words, I guess it's the act of acting out during sex, and then it's the process of getting fired up again.
The story starts with the protagonist mistaking his sister-in-law for his wife and having his way with her; Ruka Inaba's reactions are so sultry and arousing. The rest of the scenes are just average.
My sister-in-law, Ruka Inaba, visits our house quite often. One night, I came home drunk and, finding my wife asleep, I ended up having sex with her in a drunken stupor. But it turned out to be my sister-in-law, Ruka, and from that moment on, an affair began right under my wife's nose. Whispering, 'It's okay... I'll keep it a secret from my sister,' she completely seduced me.
