It was Memorial Day weekend when I and my wife went to visit her mother's. It would be a full house as her sister and husband would be staying as well. I was told that we might go swimming and I secretly hoped my sister-in-law would pick a small bathing suit.
Her name was Brooke and I had a big crush on her. She was thirty years old which was about eight years older than I was. Brooke was a dark brunette with glimmering blue eyes and pale red lips. I would guess she was a couple inches over five feet and about 130 pounds. She had beautiful double-D breasts that didn't drag like so many other busty women with a very luscious ass. She was a prime cut of woman.
Sometimes we kind of flirted. Nothing big but there were little things. For instance, I was sitting in the living room and she bent over to rummage through a magazine pile. She bent over in a way that tightened her dark blue jeans around her succulent ass and revealed an inch or so of her butt crack. With the fan on, she knew that her pants were pulling down but she kept both hands on the magazines.
Then there was another time when she came out of the shower with just a towel on. She walked around in front of me with her wonderful tits nearly popping out. I knew she was showing off and trying to make me uncomfortable. I just wanted to pull that towel off and start sucking her nipples.
The day came when we went swimming. She had chosen a two piece black bathing suit. As we swam I kept glancing at her tits and ass hoping that no one noticed. After we had swam for a couple hours we returned to my mother-in-law's house. Brooke jumped into the shower and all I could think of was that she was naked in the same house I was in.
