Being watched by the neighbor [M/F] [Voyeurism}

It was only mid-May and the temperatures were already in the low nineties. The early heat had brought heavy rains with it causing the lawn and garden to grow wild and fast, leading to long afternoons of yard work in the hot sun. The wife and I had spent the better part of the morning pulling weeds and mowing but after hours of work, we were finally finishing up and would be able to relax for the rest of the day. It was Saturday so we both had the next day off and could get away with having a few drinks by the pool as a reward for all of our hard work. I started mixing some mojitos while she went in to get her bathing suit on and grab us a couple of towels. As I went to make our drinks, I noticed our neighbor. She was in her upstairs window that overlooked our backyard. She had only moved in a few days ago so I had not had a chance to speak to her yet, but I knew her name was Chelsey and that she was divorced and had no kids. I started to wave but then noticed that she was topless. I caught a quick look at her breasts as she continued to walk past the uncovered bay window.
