I'm going on a week long business next month, and like I always do I started checking out web sites, looking to arrange a hook up or two while I'm away. I was on a fetish dating site when I saw a very familiar looking body shot. The ass and legs in the pic are one's I've stared at many times before. They belong to my sister in law. The location is right, age and other such details match.

She's always been a very conservative type. Church going, PTA member, republican, the whole works. I've always thought she was sexy, but was sure she was the last person I knew who'd be looking for something else.

I read the profile and she's talking about how much she needs to be degreaded and controlled. I started to think I had to be mistaken, it couldn't be her. But my curiosity, and my libido, were in overdrive. I set up a second account on the side, took pains to hide anything that might give myself away if it was her, and wrote her. Told her the basic truths, I'm in town for a week, looking for a nice slut to serve me, no strings. I haven't let her know it's her brotehr in law writing.

We've been exchanging notes all week. It's her all right. I've been talking about all the things I want to do to her at my hotel room. She's been asking for more and more. Begging me to tie he down, fuck her ass, whip her, piss on her, you name it. The only restriction she's asked for is that we use protection. She's already sent me her cell phone number and says she's arranged to be free the first night I'd be into town.

I can't wait for that night. I figure by the time she shows up, it will be too late for her to back out when she sees it's me. Heck from the way our letters have gone, I think she'll love the idea of having to submit to keep me from telling her husband.
