I was doing my Saturday morning yoga session in the livingroom. I had left the windows open to ventilate and feel the fresh morning air when I noticed that the neighbor across the street was watching while I did my poses. This made me really horny so I had to give him a bit of a show. I pretended to don't notice so he would think I wasn't seeing him, but out of the corner of my eye I could see his arm disappear from the window and begin to make rhythmic movements...
