She found love at the family reunion! My step-sister-in-law would not quit hitting on me, right in front of my wife even. So I decided to take matters into my own hands. I tricked her into an upstairs bedroom with the idea of a secret hookup, then I tied her up to keep her away from me. She thought it was going to be part of the sex play. Now that she's unable to get to me, I tease her with the idea of fucking her as she continues to taunt me for sex and struggle with the ropes I tied her in. Great taboo family fun!
