Tell us some more about the guy next door. I know you feel a bit guilty about it but did he get horny and go for it or did you get horny and go for it. The two of you had to have some sparks fly and wind up fucking. What happened? Was he any good? Too bad you aren't more comfortable with it with him right next door and the house empty. At his age, you could grab a fuck any time if you were a little more comfortable with it. Did his youth and energy make up for his lack of experience? You can train him and make him a lot better for you and all his future conquests.
