No one captivated me more than my wife, Ann. After three years of marriage, she is still the sexiest girl on the planet, in my estimation, especially considering the sexual experimentation we opened ourselves up to in the past year. Sex was and still is pointless unless my wife is deriving at least as much pleasure as I am from the experience.
We both know I would be lying, however, if I said Ann was the only girl who had my attention, and we have both decided we are OK with it. No, I'm not that jerk that flirts with anything wearing a skirt. In fact, I barely notice most other women. There is actually only one other girl who captures my attention in a way I cannoy deny, and it is really only because that woman is my wife's own sister, Brittany.
The attractiveness of Brittany, my wife's younger, shorter sister, was never lost on me, but it wasn't until the past year that she took up permanent residence in my head - and it was all Ann's doing, by the way. In initiating our decision to test the boundaries of sexuality within a healthy marriage, Ann had invited her sister to join us in a threesome one night. While I chose not to join myself to Brittany in an intimate way, seeing her naked, especially while she was having sex with my wife, forever sealed the young lady in my mind. From that day forward, I couldn't effectively get my sister-in-law, her sizable rack or bare round ass out of my thoughts. It eventually culminated this past summer when Brittany's husband and I agreed to swap our wives, allowing me to release my lust and have exceptionally hot sex with my wife's sexy sister.
Having that experience, which we all agreed at the time would be a one-time thing, did satisfy my urge for a little while. However, within a couple months, I couldn't help but notice how good Brittany looked in her sexy sundresses and cute shoes - and Ann couldn't help but notice the monster she created. Before long, there was no point in hiding the fact that I would enjoy another run with my wife's little sister.
Thankfully, Ann didn't mind. If it had been any other girl, it would have been a different story, but she actually sort of welcomed my attraction to Brittany, who was in many ways Ann's closest female friend. Beside, Ann was enjoying the different sexual escapades we were experimenting with in our third year of marriage as much as I was, and it wasn't fair to include other men and not at least one other woman. That woman might as well be her sister instead of some skank.
While I told myself it was for the best that Brittany not be involved in another one of those exploits, I couldn't stop thinking about that fun afternoon I had spent with her this past summer or the erotic adventure we had last year. Thing started to progress toward the end of the summer, beginning when Ann and I were moving into our new house. Brittany had come over to help briefly before going to some sort of party. There was something about the way she looked in a tank top and shorts that just grabbed my attention and wouldn't let go. While I think the other helpers didn't suspect anything, it was painfully obvious to Brittany and Ann that I was thinking about fucking my sister-in-law again.
Brittany had plans for later that night, so she had to leave around the time the rest of us were winding down and eating pizza. Once the helpers began to head home, I left my wife at home so she could put our daughter to bed while I completed some errands that are always inevitably necessitated once you begin to settle into a new house. When I returned, all our other friends had vacated the premises and one had returned: Brittany.
Brittany had come back over following a party she had been to in order to help my wife with arranging some of the bigger furniture. I joked with them by asking what they had been up to, as my mind couldn't help but wander in that direction, given our history. Both girls giggled and didn't deny that there had been any fooling around, but I'm sure they were just teasing me.
Speaking of teasing, Brittany was doing a very good job of that at the moment. The workout clothes she had worn before had been traded in for a short skirt and sleeveless blouse. Her hair, which had been in a ponytail when she had been helping us move, was now hanging loose. She was looking irresistibly sexy, and she didn't make it any easier to turn my attention away from her by the way she was lying on our couch, her legs straight out to her side, her skirt up just enough to give me a slight glimpse up toward that sweet spot I had conquered just a month ago. The way she continued to move and pose on that piece of furniture had me convinced she was trying to tempt me. I wasn't able to get her out my head the rest of that night. I even had trouble sleeping.
Not long thereafter, I found out that Brittany had indeed been teasing me on purpose. Even more, the girls had originally considered surprising me with a threesome that night, but Ann was much too tired after a fast-paced evening of moving to muster the energy for such a special session. Once again, we decided it was for the best that it didn't happen.
At some point between then and the middle of October, the sisters changed their minds again. One Friday morning I woke up to a text from Brittany confirming dinner plans for that night with her, Jack (her husband), Ann and me. I knew nothing about it, but Ann told me to respond in the affirmative. I figured it was just to celebrate that Brittany had gotten a new job and that everyone would be there. I didn't know it just yet, but it was the beginning of the most memorable week or so of my life.
