After returning from overseas, still in the Army, we got assigned to Fort Ord where I worked for Gene, a 33-year-old Sergeant married to a gorgeous German lady named Karen. We got into the habit of going camping after work Fridays and coming back on Sundays.
Gene and Karen owned a large camping trailer and we had a small tent that we would pitch next to their trailer. We had lots of fun fishing during the day, making a bon fire in the evening before going to bed. Sussy said it was getting kind of boring as she wanted to have sex more than anything else and wondered where we could find a fine specimen of a man to get that deep satisfaction of an MFM threesome.
She knew that she was free to express her sex desires and fantasies as they turned me on more than she could ever imagine. During the night we could hear Gene and Karen fucking each other through the thin walls of the trailer and they as well must have heard us but didn't mention it to each other.
During one memorable night, we stayed up listening to them fuck each other with Karen screaming for more. Sussy surmised that Gene, although he was only 5'5 and not a great catch that we could see, must have had a big cock that Sussy also wanted, and was going to get to it through Karen. I told her not to be reserved on my account and go for it. She immediately formulated a plan.
The next day she started getting physically closer to Karen really invading her private space when doing ordinary things like fixing breakfast and just talking. When Gene and I went fishing in the morning she later told me that she really put the squeeze on Karen getting closer to the point where, for most of the day we were gone they were practically touching each other, she used the intimacy of the trailer to justify being so close.
Sussy made excuses to walk past Karen in the narrow hallway of the trailer and would put her arms around her waist and once "slipped" and her arms and hands went higher grabbing her boobs, Karen who like most Europeans was very liberal, started welcoming her advances and did some of her own like staying inside the trailer more than necessary to create close quarters, trying on tiny bikinis for Sussy, and changing in front of her.
Sussy walked up to her and putting her fingers on the bikini bottom elastic ran her fingers all around it touching all around her hips with the back of her fingers. Karen had a child and had light stretch marks that I thought made her even more attractive as I have always loved imperfections and mature bodies.
That was too much for Karen who gave Sussy a still smaller bikini for her to change into doing the same round the body move on her and slowly walking around her making comments about how delicious she looked. They quickly embraced and started making out like old lovers.
She never did make it with Gene on that trip as Karen took up all her free time, Karen and Sussy seemed to have a contest of how small a bikini they could wear, needless to say, Sussy won that one hands down with a black G-string with pearls around her nipples and pussy which brought out her bumpy pussy and puffy nipples with the pearls highlighting her pussy and nipples without covering them up.
All of us agreed Sussy had the best outfit. We could not believe Gene's package when they were done modeling for us. I told Sussy that I would do some reconnaissance since Gene had invited me to go to the gym with him a couple of mornings a week and I had been declining. I would try to find out if his cock was worth pursuing.
The first time at the gym we played racquetball for a while and went to take a shower. I then understood why Karen's screams could be heard so well outside their trailer. Gene's cock was only about 6 inches or so in length, but what he lacked in length he certainly made up in girth. I would say his cock was the thickest I had imagined, at least three inches in diameter, about the size of a 12 ounce soda can. Yes, I thought to myself, he could keep Sussy busy for hours.
I noticed that Gene was easy to get hard, to test my theory I started talking about Sussy's pearl bikini and his rod immediately went up, as he was circumcised his thick dick touched his stomach and he apologized but said that Sussy was such a slut and a tease that he would do anything to fuck her. I responded that if she was for it, I wouldn't mind at all.
I asked him point blank if he had ever made it with another guy and he said casually that of course he had. I then asked him if I could touch his cock and he said "be my guest" so I jacked him off for a couple of minutes and his cock got even thicker, by the time he came I had to use both hands as one wasn't making it around his thickness.
When I went home that day I gave Sussy my full report, she of course got horny and wanted me to fuck her immediately asking me to pretend to be Gene and fuck and spank her hard, she wanted to stop after several orgasms as she said she had to save the rest for Gene. She was sure it would be OK with Karen and would proceed to ask for her permission.
Sussy went to it very direct since she had been making it with Karen almost daily for over a week since we came back from camping, plainly asking her if she could fuck Gene. Karen gave her the go ahead immediately as long as it didn't interfere with their lovemaking. Agreed.
