My wife and I had just gotten married when we moved into a small second story apartment in a coastal New England town. Houses were close by on each side of us; one house was rented by a married couple with young kids, and the other was rented by two young, rather attractive women. The neighborhood was quiet and everyone pretty much kept to themselves.
My wife is a tall, naturally beautiful, curvaceous woman (36C-24-36). I am six feet tall and played competitive tennis during and after college, so I am very physically fit. I am also an exhibitionist. I don't force it on people, but if they show a desire to look, I'm willing to oblige them.
As an example, our bedroom window was directly across the driveway, approximately thirty feet, from the upstairs window of our female neighbors. To see if they were interested in checking me out, when they were home at night, I would occasionally leave the shade up slightly, undress to "go take a shower", and then check from a darkened window to see if they had been watching. As far as I could tell, they were not interested, so I continued to be very subtle about it, and see if a spark developed.
The first time I met them was when my wife was selling her old, rusted, Plymouth Scamp. It was amazing how many people wanted to buy that bucket of bolts. As a matter of fact, our two female neighbors came by to check it out, and ended up buying it. Come to find out, they were sisters, one was 21, pretty, thin, had long blond hair and a decent figure with small breasts. The other was 24, less pretty than her younger sister, had dark hair, and an absolutely spectacular body… Zowie! During their car inspection we all became friendly and my wife invited them up for coffee, a tour of the apartment, and a prolonged chat. During the visit I could feel a mutual sexual attraction forming between the older sister and me.
From the time of our first meeting, I observed that the older sister started paying a lot of attention to our apartment and me. I frequently caught her peeping out her window at me when I left the shade up slightly. Little by little I started to give her more of a show. One time when I knew she was looking, I stood with a raging hard and let her get a long, slightly obstructed look. I even quickly walked past the window so she could get a brief, but up close viewing.
