I've swum in our pool and now I'm sunning on the lounger. By chance, I notice a twitch in a upstairs curtain next door. I'm being watched. I know both parents are out. It can only be their teenage daughter. I look carefully out of the corner of my eye and sure enough the curtain is pulled very slightly to one side. I can't see her without turning my head but I know she's there. I know at once that if she wants to watch, I'm going to show her. I slide my briefs down and kick them off. I touch my cock and fondle. I get hard quickly and remove my hand so that she gets a full view of my erection. Then I masturbate. I take my time as I would if I were on my own. It's a good five minutes before I cum. After a bit, I masturbate again. It's about the best wanking I've ever had and I've had lots. Still, I'm a little fearful I haven't been stupid. Will she tell her parents? Will they complain? What would they say? Would they tell my wife? She'll certainly tell her friends but I don't care about that. I rather hope she will. You know the guy next door to us, she'll say to the other girls and they'll giggle or roll their eyes and say gross. A couple of days later, I'm parking the car when I see her coming home from school. Hi Anna, I say, being as natural as I can. Hi Mr Wilson, she replies with a smile. That's it, but I'm sure now she was the watcher. There was something complicit in the smile. We're both pleased with ourselves.
