Based on true events ( i was the wife) : You are the husband who can't resist the temptation of your own sister in law when your wife is away at the gym. You guys have already done this before without getting caught and since she moved back in you have been trying to resist the urge to allow her in once more. Yes this is a real story that just recently happened to me and this is my way of dealing with the pain. Hope you enjoy xo Kat Tags: cheating, homewrecker, sister in law, dildo sucking, true story
