ある日の仕事帰り、自宅に着くと玄関の前に見知らぬ美女が立っていた。目が合うだけで仕事の疲れを忘れてしまう程の美しさ、ワシの人生の中では縁が無かったはずのイイオンナは、10年前にワシに好意を抱いていた元教え子のリマだった。地味で貧乳だった当時の面影はなく、美人で巨乳で色気漂う人妻に進化していたのだ。どうやら夫婦ゲンカで家出してしまい頼る当てがないようで、一晩だけ泊まらせてくれとお願いされて…。
One day, when I got home from work, there was a strange beautiful woman standing in front of the entrance. Her beauty made me forget the tiredness of her work just by looking at her. It was Rima, a student. She had no remnants of her at the time, who was sober and small-breasted, and had evolved into a beautiful, big-breasted and sexy married woman. Apparently she ran away from home due to a couple fight and has no one to rely on, so she asked me to stay for one night.
