My wife was away on a solo trip when my stepsister Ichika and I had a forbidden rendezvous... As our relationship grew colder, I couldn't resist her seductive advances anymore. "If you must cheat while traveling, do it," I thought, but reason still wouldn't let go. Day after day, night after night, we engaged in intense, creampie-filled sex that left us both satisfied beyond belief. We wanted this connection to last forever; the guilt and bliss were overwhelming.

妻が1人旅で不在の間、義妹の一花と禁断の密会…。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一花と濃密な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…。
