In this adult sister-in-law role-play, the narrator admits that his obsession with Eimi began exactly a year earlier. He was captivated by her innocent smile, translucent pale skin, and softly rounded breasts and ass. Eimi already has a boyfriend, Atsushi, who works with his wife, but that does nothing to change his fixation. When his wife and Atsushi leave for a company trip to Hokkaido, he sees his chance. He summons Eimi, rapes her, repeatedly creampies and trains her for five days as she cries and screams, then records his twisted idea of love on video.
