My girlfriend, who was 23 at the time of this story, and I were invited to a bbq by a cpl I new from work. At the time we were only involved for a month. There were 3 other cpls and a single older gentleman of about 55-60.
We had a fun time and the wine helped a lot to get us in a mellow, laidback mood. The friends who invited us and one of the other cpls eventually left. The host cpl and the single gentleman went out of their way to treat us with champagne, canapés and exceedingly risqué stories. I noticed that the husband of the cpl was very flirty and touchy with my girlfriend. I have never been a jealous person and actually found it sexy that the husband who was around 45-50, was so into my girlfriend.
The wife interestingly enough, were going out of her way to flirt with me and to keep my attention with her and away from her husband. She was around 40-45, voluptuous with huge DD's that were trying to spill out of her tight dress. The husband then announced that he was taking my wife on a tour of the house which was a very flush, modern masterpiece. The wife kept chatting to me whilst my girlfriend and the husband disappeared through the lounge doors. The older guy just laid back in his chair enjoying his drink and the mood music filtering from the ceiling somewhere.
After about 5 minutes he got up with an excuse to go to the bathroom and disappeared from the room. The wife had her hand on my leg by now and were all flattery about my looks and physic. I new something was up so I said that we should find her husband and my girlfriend and join their little tour. Off we went through the house, eventually up the stairs and then I heard it.
The unmistakeable groans of somebody in ecstasy. The wife just smiled at me and said, "How about that". I walked down the hallway with a nervous lump in my stomach, short of breath and a cock as hard as a diamond. As I entered the bedroom where the noises were coming from, I was confronted with a sight I will never forget until the day I die.
The husband was laying on his back on the bed. My girlfriend was spreadeagled over him, her tongue in his mouth and his cock buried deep in her pussy. Leaning over her back with his cock also squashed into her pussy, was the older guy. They where double fucking her with violent gusto and she was loving every second of it.
The wife stood behind me and wrapped her arms around me, playing with my nipples, pushing her big tits into me and whispering in my ear " Look how she is taking their cocks! She is loving it and she wants you to see how she craves strange cock!" Something to that effect.
I can honestly say that it was the first time I ever came without touching myself. Big ropes of cum shot out of my cock and soaked my pants.It was the sexiest thing I have ever seen! The girl I loved, who would later become my wife, was split open by two big cocks and I wanted more!
The night turned into a blur of fucking and sucking. At one stage the older guy was laying at the bottom with the wife on top of him and I was on top of her, both our cocks in her pussy. The rubbing of his cock over mine had me shoot strings of cum over his cock and in her pussy. He let go and i could feel his cock pulsing and the soaking feeling of cum over my cock and balls. She then turned around and pushed me onto my back and slowly crawled up my body until she was squatting over me with her pussy in my face. She started to mash her pussy into my mouth whilst saying " Eat all the cum. Suck me dry. Clean me up. You've got to practise cleaning because I bet you are going to clean your girlfriend's pussy from strange cum in the future" or something to that effect. I happily obliged.
Later that night I took my time giving my girlfriend a tongue bath. We were married 2 years later and are still happily together after 20 years. She runs her own business successfully, is a good mother to my son and loves to fuck strange men on European beaches or in swing clubs all over the world. She still feeds me cum directly out of her pussy from strange cocks.
