My wife was away on a solo trip when my stepsister, Ai, and I had a secret rendezvous... Our relationship has been growing cold, but I couldn't resist her seduction any longer. Even though I knew she was cheating on me while she was traveling, I just couldn't help myself. "If you're going to cheat, might as well be with someone hotter than me," I thought foolishly. We engaged in nonstop erotic sex throughout the day and night, morning after morning, leaving me completely spent each time. It felt so good to be connected like that; the guilt and bliss were overwhelming.

妻が1人旅で不在の間、義妹の愛と禁断の密会…。夫婦の関係が冷めて行く中で、彼女の誘惑に耐えることが出来なくなって…。「どうせお姉ちゃん旅先で不倫してるよ…」それでも、ダメだと思うほど理性が吹き飛んでいく…。昼も夕も夜も翌朝も、妻よりもずっとエロ過ぎる愛と濃密なSEXを繰り返し何度も何度も中出し。互いに求め続ける最高の一時。ずっと繋がっていたい。背徳感と多幸感で頭がとろける程気持ち良過ぎた…。
