This is a TRUE story...
This all happened back in the early nineties. My wife to be, my fiancé, was away doing an internship the summer before graduation and a year before our wedding. I was bit jealous in a boyish way that she would leave me for an entire summer. Although I surmised that would allow me to work hard, save some real money, and be ready for our new life after the wedding.
My summer was started in a blur and I work twelve hour days in the sun and was in the best shape of my life. I was working construction and work long days 4-5 days per week. On the weekends I would visit my parent's summer house to water ski and hang with the family. It is there that the story gets interesting....
My in-laws, to be, owned a resort where my parents had their place. So my looking for some side action was a big no-no. My sister in law who was two years younger became my pal. She had ended a serious relationship and didn't want another before school in the fall. We spent a lot of time on the boat and in the bars getting shXt faced and falling down drunk. On many occasions I would spend the night at the family house in town as I could not drive back to the resort. We would tease each other and talk a lot about relationships and sometimes worked around the discussions of sex and our experience. She was younger and purer and was all ears. I had described oral sex with others to her and could tell she had not experienced the bliss of being eaten by a madman!
