This was in 1978.
My wife and I had been married a few months after living together for over a year. My wife is 5' 4" and about 120#, Brown hair and eyes. 38D tits with dark nipples, a very hot pussy with a long clitoris back then she did not shave her bush. I am 6' 3' around 195# 6 1/2 inch thick dick.
We had a friend of ours over for a shrimp boil and to party. After about an hour my wife said she had a bad headache and went to lay down. After about 10 minuets she called me to the bedroom I walked in and she tells me she is so horny I kissed her and said Keith is here and had the water on to boil the shrimp. This came from left field because we had never talked about adding another to our sex life. She says turn the water off and tell Keith to join us.
I went and told Keith that she was crazy horny and wanted to know if he would like to join us and fuck her. He said he had dropped the shrimp in the pot and did not have a girl with him to share and said no, but would finish with the shrimp and leave but for me to go take care of her. I went back to the room she was naked on the bed with her legs wide open playing with her pussy. It was the wettest I have ever seen it.
I took my clothes off as fast as I could and got in a 69, I was licking up her juices, as I am coming up for air I see Keith in the doorway I spread out her juicy pussy for him to see hopping he comes on in and joins I even waved him in. She is sucking my dick like never before. I went back to licking her pussy when I looked back up he was gone. I heard him in the kitchen next thing I know he is at the door and telling us he was going to head out. I said man come on and get in on this pussy but he said thanks but was going to leave.
After he left we had the hottest sex we ever had. After we caught our breath, I asked her where that came from? She said she got so horny she just needed to be fucked and right then.
After that I would make up stories with other people as we had sex and this would make her so wet. Over the years we ended up having a MMF but oddly enough it took a few tries. After that things got really hot 3 sums, swinging, and DVP's.
I know this is not a very hot story but I would like to tell all about our sex stories in more detail.
