My best friend and I met in 1 st grade. After we graduated HS, we joined the Army together and did a 3 year tour for college money.
I had a gf in HS who was a sophomore at the University we went to. My best friend soon found a Freshman girl and started dating her. Summer came around and we both went off for 2 weeks reserve duty. The second summer session we took more classes, so we could graduate sooner. That turned out to be our summer routine during college.
So when the fall semester started, I found out she had been dating a guy for 3 years from our HS who was at another university. After a good weekend of banging her brains out ended up dumping her that Monday. That left me free.
As soon as that happened I end up hanging out with my buddy and his GF, sometimes at her apartment. There were 3 girls staying in this 2 BR, 2 bath place. I dated around some, but A year later I got set up with his GF's roommate after a spring breakup. They were sharing a room. From then on we dated these girls through college. By graduation, we were all engaged. We had a double wedding, and even same honeymoon destination.
A year after getting married, we were all hanging out (he and I got a job at the same company headquarters. Our wife's also got jobs near by) nearly every weekend. We even lived in the same small apartment complex. So one rainy weekend we all started drinking at lunch. By the time dinner was over we were all pretty trashed. Around 8:30 that night the thunderstorm knocked out the electricty. So no more tv, we started talking that lead to a round truth or dare, which lead to more drinking. We normally didn't talk much about sex, but it came up and got deeper. Started out with how many partners have you had? I had 2, my buddy said 3 (I knew about 2 because we were so close, but had no idea about the 3rd), his wife said 1 and mine said 2.I pretty much knew she wasn't a virgin when had sex the first time during the late fall of our senior year. My wife asked if the two husbands had ever had sex with the same girl. That was a no brainer, definitely a yes. Then his wife asked if who had ever had a 3 some? I was surprised to hear everyone had. Then there was a bunch of questions that I don't remember the answers, like skinny dipping, being nude in front of other, going commando, ..... by now we were all very drunk and very horney, and it was raining cats and dogs outside. I was feeling up my wife and he was feeling up his. I wasn't really paying attention to his last question how many wives had sex with the same guy? Both said yes. I had gotten up to go to the bathroom as they were answering. After peeing I came back and everyone rotated to pee.
I was about passed out when she came back. We started making out. She was unbuttoning my shirt, I was feeling up her tits under her t shirt and had slipped her bra out of the way. All of the sudden she sat up, pulled off her t shirt, and pops her bra off in front of everyone, but since the batteries were getting weak, it was pretty dark in there. They were sitting in the other end of the L shaped sectional, she was facing them.
All of the sudden the electricity came back on, and so did the lights. That left her tits fully exposed, but she made no effort to cover up. I looked aroundat my buddy and his wife, his dick was out, hard as a rock, she was was sucking and jacking him off. I looked back at my wife and noticed sometime when the light were off she had pulled her panties off and her skirt was up high enough that I could see her pussy. Based on his angle he had even a better view. She then spread her legs a little more, and started rubbing her clit. I looked at her and said Dear!, by now his wife had turned around and said, Oh don't worry, he's seen it lots of times before. Then my wife said and I've seen his dick plenty of times too.
All the sudden it struck me. Both wives said they had both had sex with the same guy, and his wife had said she had only had sex with one guy (obviously her husband). That ment my wife had had sex with my best friend. I didn't get too upset because it had been before we started dating. Well my buddies dick is a whole lot thicker than mine and maybe an inch and a half longer. In fact it kinda made me hornier. A short discussion and confirmation, and they got up, he stripped totally nude, she grabbed his dick and they went to their bedroom.
As they were leaving the room my wife stood up and dropped her skirt and was also totally naked.
We fucked like rabbits that night.
Next morning, we all get up for breakfast. His wife was dressed and in the kitchen. I got dressed and went into the kitchen. Shortly after he comes in totally nude with my wife right behind. I was a little concerned, but his wife was fine with it.
After a little bit I said, why don't we all just get nude. His wife said go ahead, my wife said I'm good with it, so I started stripping down. Then I took my clothes into the livingroom. When I came back I was expecting his wife to be nude, but she wasn't. She did take off her robe, her pj's definitely weren't see through, but it did show some shape.
That Sunday we all discussed what was going on. So here's the bottom line. The two girls had had an unknown number of 3 sums during college. Even a bunch after my then gf were dating, and a couple of times after we were engaged. My wife said she enjoys having sex with me, but wished she could have another 3 sum with them. His wife said she misses it too would love it! He was just smiling. I asked about a 4 sum or swapping? His wife said she couldn't do that. In fact she wouldn't even agree to being nude in front of me. She said she could wear a bikini when we were nude. So the rest of that Sunday and many many times since his wife wore a bikini and we were all nude.
For my wife's next birthday, I asked her what she wanted. She instantly said a 3 sum, with them. After a week of trying to get out of it, I finally gave in. But then I asked if at least I could watch. She said no, because I would see his wife nude if I was there. They finally agreed that his wife could video it and I could watch with my wife later.
So my wife has been having 3 sums with them around 5 times a year. I've briefly seen his wife's tits a couple of times, thats been it.
