I could hear her breathing getting heavier.I sensed her sadness while I was walking away but I knew it would be too risky to try anything with the sex...y teacher in the parking lot.We texted at night. She told me how she felt a little lonely and bored in a new city and asked me if there was anything fun to do during the weekends. I asked her to define fun as there were plenty of options in the city.She sent me an emoji and told me to take charge calling me the expert on the matter. I got excited. When he saw her, he stopped short and whistled.To his surprise, Cindy stuck out her chest, put her hand around her hair, and duplicated a pinup pose. He took her in his arms and kissed her. "Cindy, you look gorgeous! I've never seen you look better. But what was that action a moment ago? Just a few months ago, you would have taken a swing at my head. What happened?"She grinned and replied, "I finally recognize the whistle for what it is. It's a whistle of admiration, isn't it?" It sure is, but. "I was nervous, but already committed to this. I pulled down my underwear and stood naked form the waist down in front of a beautiful woman for the first time in my life. I saw a bit of a smirk and maybe a smile cross Melissa's face as she looked at my cock - did she laugh? She looked me in the eyes and with a devilish look on her face she said "stroke".I stood there harder than I'd ever been and began stroking my cock with more intensity than I ever had before. I was ready to cum within. It was just me, a slight breeze, and the crickets — I thought.Glancing to the side, I suddenly noticed the woman from two units over, who had silently stepped out for some air, leaning on the nearest railing watching me intently.I froze, hand on my cock, and pretended not to see her. As if she was some predator that could only see motion — ha! I was totally nude, and totally caught, without even a towel nearby.Was it time to act out the fantasy?Out of the corner of my eye I could see her still.
