Fucking while she watched

This about our next door neighbor, a female around my wifes age which at the time was 35 years old, she was single and very friendly with us. I remember once sitting outside with my wife having a few cold beers on a hot summer day, she came over and had a few cold ones with us. Somehow we started talking about sex and then we invited her inside the house to watch me and my wife having sex. She agreed and even asked my wife if she could lick her pussy, my wife agreed and my neighbor went down and started eating my wifes wet pussy. By this time my cock was just throbbing hard, so then I began to fuck my wife doggy then my neighbor asked If I could shoot my cum load on her face, my wife said it was ok with her so then I pulled my cock out of my wifes pussy and shot the load in my neighbors face.... That was really great and so much fun. I never did get a chance to fuck my neighbor, but I really wanted to give it to her in the ass bad....
