I watched my wife fuck our neighbors son

I've been telling my wife for a while that I want to watch her get fucked. She finally agreed, but she wanted the neighbors son to do it. He's 19 and my wife is 40. We invited him over to swim and a few minutes later my wife asked him if he wanted to skinny dip. He said yes so we all got naked. We swam for a while and then got out and we all went into the house naked. My wife saw that he was rock hard and took him by the hand and led him into the bedroom and she started stroking his cock as I watched. She sucked him for a few minutes and then they did a 69 for about 5 minutes. She then got on top of him and she took his cock in her hand and slid down onto it. She rode him hard for about 10 minutes until she orgasmed. Then he got on top of her and fucked her until he shot his load all over her shaved pussy. It was amazing to watch her cum with his big dick deep inside her and then watch her get covered with hot cum. I got onto her and I finished in her wet pussy while he sucked her tits. It was a great time and we plan to do it with him again. He said next time he'll bring his girlfriend for me to fuck while he fucks my wife. I'm fixed, so he told me to cum in her. I'm really looking forward to that. Since then I've watched my wife fuck two other guys and scissor and 69 with a girl.
