My parents and sister were out of town looking at colleges for the weekend leaving me home alone. I spent some of the time hanging out with friends doing normal things but Saturday afternoon I was home alone and went swimming in our pool. Our house backs up to a field and a wooded lot so is semi private except for the neighbors on either side. After a short time something came over me and I took off my bikini and swam around naked which then turned into me laying on one of the lounge chairs fingering myself until I came. That led me to spending the rest of the afternoon and night hanging out in the house naked and playing with myself all over the house. I'm not sure if any of the neighbors saw anything though.
