My wife and I spent the day in the garden a couple of days ago as the weather was great. We have a double sunbed that we use. We put a blanket up on one side not to upset the older couple next to us and sunbath naked. On the other side of us is a single mother with a couple of girls at college, who we dont mind if they see us naked in the garden. We had been out all day naked which I love to do and because my wife is naked I do get hard from time to time, which I just let happen I love having a hard cock. I love to rub sun cream into my wife because it makes my cock hard and she knows that she as control over me, but I get to touch her tits and bum, so I am more that happy. We had heard that Ali was in next door and she had opened the windows to the upstairs while we were sunbathing. We could hear Ali from time to time walking into the bedroom and she was maybe doing this to have a look at us naked. I find this a big turn on. I was get to the point that I wanted to have sex so we started kissing and I was playing with my wifes tits. I asked my wife to lay on her side so that I could make love to her. I slipped my cock into her pussy and made love on our sides. I just pushed my cock inside her very gently to enjoy the feeling of making love to my wife in the sun. My wife gets so wet it is so sexy to feel. I played with her until she cum while we made love and I felt her pussy grip my cock. We carried on making love for a while and she decided to suck my cock and make me cum. I was layed on my back watching my wife and it was great. We was not being noisy and we had not heard Ali next door, when I looked up and caught Ali watching from the bedroom window. When I cum in the mouth of my wife it was the best thing ever, also aware that Ali had been watching what we were up to. We countinued to sunbath for the rest of the day naked and make love agan later and I did think about Ali watching us.
