I downloaded it from a DL on notfourchan at the start of June but I lost it when my HD crashed in July. Since then, I've been searching for it online, but I can't remember the exact title of this single story, which was just one word that was synonymous to either imprisonment or rehabilitation (rs.4chan was no help). The summary of the story was that there was this salaryman who kept this young female junky tied to a bed in order to break her drug addiction, and everytime she went through withdrawal syndrome, he raped her instead as a therapy; after a week, he realizes that she's already finally free of the cravings, but by this time, he has become dangerously addicted himself to sex because of her, so much so that he has lost track of time and can't bring himself to leave her side.
