This is a story of a young married couple who experiment with sex and eventually end up Bi swingers. The husband looses his virginity to a neighbor in his apartment buiding while both wives cheer them on. There is a variety of sex here but I guess you could classify the overall topic as BI friends . When I returned from my tour of duty in Japan I was a much wiser guy. I entered the military just out of HS and really had little experience with women. I had fucked the school tramp one night along with some of my friends. It was quick and over with before I knew it and most of my juice went on the ground beside her. We all fucked her and she blew a few guys before we took her home. I was not too impressed with sex at that point but that all changed when a buddy stationed with me took me to Tokoyo on my first pass after arriving in Nippon land. He had been there for nearly two years and really knew his way around. It was peacetime and Japan was booming after the second world war. John Halstrand was my buddy's name and he asked me to call him "Jack" as his middle name was Jackson. Jack took me to a street in Tokoyo noted for sex shoppes, hookers, and girly-boys who catered to the gay tastes. I found out you could buy any kind of sex you wanted there. He took me to a live sex show where the tiny Jap woman fucked a donkey and also later a giant mastiff dog. My mouth must have dropped open as I observed the massive donkey dick slip inside her tiny body. She smiled from the stage as she worked him into her deeper and deeper. I knew that day I had a taste for the bazarre as my dick got hard as a rock. Jack smiled and said as I rubbed my cock unashamedly, "Your goin to enjoy Japan, I can see that as he looked at the bulge in my uniform trousers. I blushed and pushed my cock between my legs a little farther. We spent the entire weekend in town and I sampled my second piece of pussy ever. We ended up finally at a nice little whore-house just off the main drag. There were three whores sitting in the window of the rice-stalk building. Jack discussed price for me and soon we were being led down a narrow hall toward a large room with slding walls and paper-like windows in the doors. Jack told me the Japanesse used a lot of ground rice stalks to build their houses as wood was expensive and scarce. They were also less likely to crack when the Island trimbled from the earth tremors that occured constantly. We both went into the same big room and undressed. I was average in size as far as my penis was concerned but Jack definitely was not. The girl he was with started to babble in Japanesse and point toward hs dick. He haggled with her but she kept telling him no. She told him in broken English to wait a minute and she left the room. She returned in few minutes with another girl. :This girl for you, G.I., you too biggy boy for me!" Jack was satisfied and we were then led to a big sauna which was heated with hot stones laying in the bottom. I unwrapped the towel they had given me and stepped into the water about ankle deep. I almost screamed as the scalding water turned my feet beet-red instantly. Jack and one of the whores helped me out as I danced up and down trying to cool my feet and ankles. '"You must enter it very slowly," Jack said as I agonized over my cooked feet. "Thanks a lot , you son of a bitch" I said good naturedly but half serious too. He burst out laughing along with the whores and about twenty minutes later I had managed to get into the water up to my waist as I sat on a little ledge. We sat and relaxed and when I was ready to get out I was drained and they had to help me to the room. Jack was ready to go as I lay and cooled off. He was one of these guys whom you could not embarrass and didn't worry about anything. He was from Minnesota and had done some lumber cutting and you could tell it by his physique. But his cock was his clame to fame!!! He was over ten inches when erect and thick as a post. He really had trouble getting some of the Jap women to fuck him. Several times we would have women in different rooms and I would just get started when he would slam open the door and say,"Let's go. my bitch won't fuck me!" We would get up and leave to look for another woman for him. But during my two year tour , we sampled everything avaiable almost in the way of sex deviations. I even let him talk me into letting a Jap TV suck my cock one night as several other people looked on. I had been fortified by several bottles of good NIppon beer which made it easier. I didn't tell Jack but I really enjoyed the best blow-job I had experienced to that point. The most drastic sexual act happened one night as Jack watched a tiny little Jap women fuck me with a small six-inch dildo. My postate enjoyed the first one but when she put on the big one I stopped her and we left. Jack called me "Chicken" for several days before forgetting it and letting it drop. Jack's time was up before mine and he shipped out to return to the U.S. and his discharge. I really hated to see him go and I wrote him for awhile and we made all the promses that G'I's make but never keep and soon he stopped writing and I never heard from him again. I still think of him at times and remember watching him shove that massive meat into a tiny little 80 pound Jap whore as she twisted her face in pain, determined to earn the "double" money he had promised her if she would fuck him. They looked like a colorful butterfly pinned on his shaft. Many never made it to the end and he would leave them laying on the mat in pain as he pitched their money down beside them. I will always be grateful to him for helping educate me sexually and that is where my story really starts: I returned to the U.S. and got a job on the east coast in Arlington, Va. working for the Governmet doing almost the same thing I did in the military but making much more money. I settled in a pretty nice apartment in Fairfax, Va. and I started to go out at night to make some connections. That's when I met another guy who was to greatly influence my life. ..........The sex is about to begin so come back for the second part and I will tell you what happened
