Before I start, let me say that my sister in law, we will call her Amber, has never spent very much time talking with me. I am fifteen years older than her and I didn't think we had much in common. We would make small talk and every so often she would talk to me about sports and that was it. She wasn't rude but never went out of her way to try to get to know me as I had first tried with her. She is a cute girl, with long hair and a great body with huge tits. Here is how I found out about her body.
For the first two years I knew her, I never saw her in anything other than a big sweater or very large t-shirt. I just thought she really didn't care about what she looked like until one day in the summer when I was in the pool. Amber came up on the deck and asked how the water was. I told her it was great. That's when my opinion of her changed very quickly.
She took off her shorts revealing some long attractive legs and then she grabbed the bottom of her t-shirt and pulled it over her head and my heart skipped a beat. She had on a very plain one piece swim suit but contained in it was the biggest pair of tits I had ever seen on a girl her size. They were easily DD if not bigger. I could not stop staring at her. She got in the pool and started swimming around and I tried to think of something else.
About ten minutes after she started swimming around she came over to shallow side of the pool where I was leaning against the wall drinking a beer. She didn't stand all the way up but she was kind of crouched down just enough for her tits to be right above the water line. Amber then just started talking to me like we were old friends. She was joking and talking about sports with me and then she asked for a beer. I told her they were on the deck in the cooler. She swam away and got two beers and brought them back. She handed one to me and kept one for herself.
I opened mine and took a drink and watched her struggle with the cap. All the while, I was really watching her big tits being squeezed together as she struggled. Finally she gave up and asked me to open it. I jokingly asked what's in it for me and to my great surprise Amber responded that I already had been rewarded enough because she knew I was staring at her tits the entire time she was trying to open the beer. We both laughed and that was it that day as my wife and brother in law then joined us in the pool.
About two weeks later my wife came outside and told me her brother and Amber were coming over and I said OK. This time I was cleaning the pool. When they arrived I spoke to my brother in law for about ten minutes as Amber went in the house with my wife. Then out came Amber wrapped in a towel and my brother in law went in the house.
Amber and I started talking and she asked if I minded if she floated around on a raft while I cleaned the pool. Of course I said OK and this time I was smarter, I had on sunglasses so she wouldn't know I was staring at her tits. What I was not prepared for was what happened when she took off the towel. She had bought a new swim suit that was nothing like the plain one from a couple weeks ago.
