Visiting up North

Each year at Thanksgiving I travel north to visit with my sister and her family in Michigan. While I was there this year they planned a trip to the cabin.It is more of a large secluded house. My sister and I were the first ones to arrive. We made the beds and got things ready for everyone. My niece and her family got there and agreed to go out for groceries. My sister went with them to pick the wine and I stayed behind to shower.

The water was hot and felt good, It was relaxing to be alone and take as long as I wanted, When I was finished I dried off and hung the towel to dry.
I walked out of the bathroom naked to dress in my room. I thought I was alone but at the end of the hall was my nieces father in law.

I just froze and was saying I'm sorry. He laughed and told me I look nice.
I smiled and hurried to my room,
I was a little shocked when he followed me to the bedroom. He said he had wondered what I looked like naked. I told him now you do!
All of a sudden I was horny like a school girl. I told him to come in and hurry before anyone else showed up.

We had great quick hard sex and were back in the living room before my sister and family got back. No one suspected a thing. I spent most of the next night in his room while my sister slept. He went back home the next day but I can't wait for next year!
