I've fallen for my wife's sister, Eri. She's kind and has a great personality, with an overflowing allure of mature sexiness—a truly amazing woman. I want to embrace her tantalizing body to my heart's content... However, Eri has a husband, Kojirou. Still, my feelings for Eri only grew stronger. One day, my wife went on a business trip and left Japan for five days. This is my chance! I called out Eri, raped her, thoroughly trained the screaming her, and recorded my love that was driving me mad.
