My family decided to take a vacation together to Las Vegas. To my surprise me and my brother in law arrived, unexpectidly, about a day ahead of everyone else due to our schedules. He and I have always had a very flirty relationship, with alittle bit of touchy feely over the years, but with no one around to cool the flirting, things soon got way outta hand after a few drinks. I was soon straddling him with my tounge down his throat. The passion was incrediable as this is something we have both wanted for along time!! I sucked his cock while smoothering his face with my sloppy wet pussy until he filled my mouth full of his cum ... Does the fact that I fucked my husbands brother make me a bad wife? probably but it also makes me one hell-of-a great sister in law!!
