My mother-in-law is a hair dresser so she cuts my hair. I never minded it because it saved me a few bucks and she's pretty good looking. I have to admit that I liked it when she pressed her tits or her crotch against my body when she'd be cutting my hair. It turned me on, and usually I headed straight home and fucked the hell out of my wife because I was so horny. Then one day I told my wife about this and she didn't seem to be upset about it at all. Actually it seemed to turn her on too. The next time I went for a haircut she couldn't wait for me to get home and fuck her.

Then a few months later she told me that she had told her mother all about what was going on, that I liked it when she rubbed up against me and that it got me horny. I got kind of pissed off, telling her that that was something I had told her in confidence. I asked her how could she expect me to look her mother in the face after she knew that. My wife said that her mother didn't seem to mind at all, and that she said that her mother considered it to be a compliment.

The next time that I went for a haircut my mother-in-law seemed to be deliberately pushing all of my buttons, shoving her tits into my face and rubbing her crotch against any part of my body that she could. Her nipples were as hard as rocks, and so was my cock. I told her that I knew that she was doing and she said, "Good, that'll make things easier."

When she was finished cutting my hair my mother-in-law led me into her bedroom and we spent the next hour fucking. It had to be the best sex I had ever had. When we were done I begged her not to tell her daughter and she promised that she would never do anything like that. Though she did make me promise that I would have sex with her whenever she asked me to, no matter what.

So far my mother-in-law hasn't been too demanding. It's a given that I have to fuck her every time she gives me a haircut and at least once whenever my father-in-law is away on business. Other than that she hasn't been on my case. The thing is, I'm not all that sure that my wife doesn't know about what's going on, and if she does, I don't think that she minds.
