田舎に暮らす義母が初めて僕達夫婦の新居に泊まりでやって来た。義母は最近ヨガにハマっているらしく、その姿を見た僕は不意に義母の色気を感じてしまった…。よくよく考えたら義母はまだ若く、とても男心をそそる、何とも言えないエロい身体つきをしていた…。妻とのセックスレスも相まって、僕は義母の身体を想像し自慰にふけっていた。運が悪いのか…いや運が良かったというべきか…僕の自慰行為を目撃してしまった義母。その事がきっかけで、ある事を提案する僕。母親である責任感、僕への情け、そんな気持ちがあったのだろう…。義母と僕は禁断の関係になっていくのだった…。
My mother-in-law, who lives in the countryside, came to stay at our new home for the first time. It seems that my mother-in-law has recently become addicted to yoga, and when I saw her doing so, I suddenly felt her sexiness… When I thought about it, my mother-in-law was still young, and had an indescribably erotic body that was very appealing to men… Combined with the lack of sex with my wife, I was indulging in masturbation while imagining my mother-in-law’s body. I guess it was bad luck… or should I say good luck… my mother-in-law witnessed me masturbating. This prompted me to suggest something. I guess she had some feelings of responsibility as a mother and pity for me… My mother-in-law and I were entering into a forbidden relationship…
