We are what you would call "seasoned" swingers. I met my 2nd and current wife Anna in 1999 in the Philippines. We got married in the USA and then after a few months we went back to the Philippines to visit my wifes family and have another ceremony for her family. When we got married it was with the understanding that we would live a swinging lifestyle. Her twin sister (Sylvia) and her cousin (Maria) live with us in a four way loving relationship and share in our swinging lifestyle. We are pretty well off and I am semi-retired but I still travel a lot (about 10 % business and 90% for pleasure). Over the years my wife has gone with me on trips less and less unless it is a really fancy place. Her favourite place so far is Bora Bora. If it is a trip that involves a lot of adventure and outdoor activities my wife's cousin will usually go with me. If it is a mostly a business trip my wife will let Sylvia her twin sister take her place. If it is a trip that involves going to other swing clubs then all 3 women usually want to go. At the time of this writing we (the 4 of us) are currently on a trip to Europe. (We live in the USA) My wifes sister (Sylvia) is very submissive sexually and likes the idea of multilpe men and has gangbang fantasies where she is being restrained. Sylvia also has a "cum fetish" and wanted to be used as a "sperm receptacle" by a group of men. Recently we went to a swingers club in the Frankfurt area and it was quite fun. I fucked 3 different women and each of the girls got fucked several times (all with condoms). While we were there we did some asking around and were able to arrange for a group of seven german guys the following day in our hotel suite. They were early 20's to mid 30's in age. It was early (about 6pm) when they showed up as a group. I met 3 of them the previous day at the club but the other 4 were invited by the other 3. The girls were in the bathroom when I let them in. Then the came out with Sylvia naked wearing a blindfold and my wife and Maria were topless with just G-strings and they help guide Sylvia to the bed. The guys all knew what we wanted. When we are home there is a small group of friends (3 other couples) that we will have unprotected sex with, but this was to be strangers without condoms. I think Sylvia got this idea from some japanese porn that we viewed that featured an actress that got fucked and creampied several times and and then more guys that were jacking off who would just insert into her pussy and come. Sylvia mentioned that those scenes where really hot. So we wanted to make Sylvia's fantasy come true. We had pretty good assurances that the 7 german guys were clean. My wife and her cousin did the "fluffing" getting the guys hard. My wife helped Sylvia get ready. She was blindfolded and tied to the bed. She also had a ball gag put into her mouth. The guys knew the rules. They each had about 5 minutes they were to try to hold off cumming until they next round. All the guys followed the rules and made a deposit on the second round. After the seventh deposit I asked Sylvia if she wanted to continue. She nodded her head yes and I took a turn in a really sloppy mess while the other guys were getting hard again. Eventually each guy deposited a second load. The guys all got dressed and left. My wife got between Sylvias legs and started cleaning her with her tounge. I was wondering for some reason how much cum was inside Sylvia and how much was coming out for my wife to comsume. I was hard again and Maria got into the doggy position next to my wife. I plunged into Maria and fucked her for a few minutes and then I switched to my wife for a few minutes while Maria took over the cleanup duties. I switched back and forth several times until I was ready to come. I had My wife lay down on her back and Maria straddled my wife in the "reverse cowgirl" position so that thier pussy's were right above and below each other. This is my absolute favorite way to come. When I felt the first spurt go into Maria I pulled out and quickly plunged into my wife in order to finish off. Then I alternated from one pussy to the other. Eventually I pulled out to rest for awhile and Sylvia then performed cleanup on them both. We showered and rested and then about an hour later we got dressed and decided to go back to the same swing club. The girls danced in crotchless sheer or "fish net" body stockings and little black mini skirts. I danced with my wife for a while and then another couple danced close to us with the man behind the woman and the woman grinding her ass into his crotch. I moved my wife into the same position. My wife and the other woman were facing each other and got closer. The woman started putting her hands on my wifes hips and then breasts and then they kissed. The guy made a motion with his hand that I took as asking if we could swap. We quickly swapped positions and I got behind his wife. Almost immediately his wife reached behind her and I thought she was trying to slow things down. But she was reaching for my zipper. She pulled my zipper down and got my cock out. Because of the previous two cums that evening I had taken a blue pill to keep my dick hard. I thought that she would just continue grinding against me to feel my cock outside her panties. But she did not have any panties. My cock was rubbing on the outside of her pussy. And she was trying to manuever her hips to get my cock inside her. We did not even talk to this couple and I could not believe how quickly things were happening. My wife gave me a "come closer" motion and then we got where we could hear each other over the music. She said "He is rubbing his cock on me. Are you OK with it?" I just said "sure... if you are" Then she said "what about more?" I said "Sure... whatever you want to do". I was not really thinking at that point. Within a minute I was inside his wife and I could tell he was inside mine. We were trying to keep doing a grinding dance so it would not be apparent that we were actually fucking. In the USA most swing clubs have seperate "play" areas and discourge open sex in the main club area. But this club I don't think it mattered because I saw a woman giving a guy a blowjob at a table near the dance floor. So pretty soon by our thrusting motions it was really obvious that we were fucking. After two more dance songs I was emptying my balls into a stranger. The other guy had finished also. The woman just gave me a hug and kiss on the cheek and then the couple left the club. Me and the wife went back to our table. I asked if the guy said anything to her. She said " no. nothing" It was first for both of us. I have fucked a lot of strange woman but this was the first time that I fucked one without saying a single word to her. My wife said the same. It was the only time she had sex without talking to someone first. We had a drink. And then I started thinking about the load deposited inside my wife. I suddenly had the desire to get her alone. A weird desire came over me. In so may years of swinging I have never eaten a creampie and for some reason I wanted to go down on my wife right then. I have fucked in sloppy seconds many times but had never had any desire to take a taste. I think it was the fact I didn't know the guy and had very little chance of ever seeing him again. I took my wife to one of the private areas. We got naked and I got between her legs. She noticed what I was about to do and said "I think I should clean up a little first" I just started licking her. My dick was getting hard again. I ended up fucking her to orgasm and this was my forth time cumming for the evening. We went back to the table and Maria went with another couple into a play room for about 30 minutes. Eventually we left the club but when we got back to the hotel room it was about 3 am. Maria was playing with herself and I got into bed next to her to help her out. My wife and her sister had gotten into the other bed and fell asleep quickly. As I was about to go down on Maria she said "I need to clean". I was thinking that she must have also gotten fucked without a condom. I just ignored her and started to lick her pussy and confirmed my suspicions. I don't think I will be making this creampie eating thing a regular thing. I don't feel that any part of my sexuality has changed. It just seems like eating a creampie is something that I was previously adverse to doing; but now I am not averse to doing it under the right conditions. I think being away from anyone else we may know and the whole "stranger" thing is something we will continue to explore.
