The following story is going to sound like it was made up to go in a men's magazine back when they were popular. I assure you that it is true and only the names have been changed to protect the guilty.
My wife is Karen and I am John. Karen is a 5'8" tall, large breasted, thick blonde, think Anna Nicole Smith in her prime. I am a normal looking 5'10" tall brown-haired guy with broad shoulders and large build. At the time this story occurred we were both in our early 40's and had been married for over 20 years.
One Saturday in March of 2000 we met another couple, Robert and Nicki, at an adult theater in Dallas during a couple's night. Nicki is about 5'4 with C cup breasts, blonde hair and a thick body. Robert was a 6' tall, lean blonde guy with an athletic build. They too had been married for a long time and were just a couple of years older than us.
We had been to this theater a couple of times before but this was Robert and Nicki's first time. Karen likes to tell the story of how Robert and Nicki were standing up against the back wall and Robert pulled Nicki's top down showing me her chest. Being the tit man I am, it drew me in like a moth to a flame. Apparently, Robert had gotten a look at Karen's ample chest and he wanted to meet her. After a short discussion we all adjourned to a small nearby viewing room.
Once in the room Nicki and I took to the couch while Karen and Robert had nowhere to go, so they went for the floor. In moments we were all mostly naked. I had my face buried in Nicki's pussy while she moaned appropriately. Robert had Karen on her back with his cock buried up in her pussy. After Nicki came, I moved up and slipped my quite hard cock into her and pumped till I couldn't take it anymore, pulling out and shooting all over her stomach and tits. Robert did the same to Karen.
