First Bi experience

My first bi experience happened a few years back while still working in western sydney area. After work, I decided to have a drink at an Irish pub in Parrammatta. It was fairly a not so busy night with only a handful people drinking at the pub. A friendly young muscly German bloke casually approach me and began a friendly chat. He offered to shout for a schooner of beer and asked what my background was. I thought, perhaps that night being the only Asian guy in the crowd made me look interesting. He introduced himself as James, originally from Germany who got married and settled in Epping. I shouted back the next rounds of beer. When I came back to the table, I noticed that he briefly went out of the pub and was talking with someone on the phone.
When we resumed our drinking and chat, he told me that it was his Sarah, his wife on the phone asking him to go home as it was getting late. He then straightforwardly asked "hey mate, would you consider coming home with me to fuck my wife tonight?". "What?? I replied". I got shocked and almost fell to the chair. Back then, I was so naive about the swingers/threesome scene in Australia after freshly coming from overseas to work in Sydney for a 6 months contract.
"Are you serious James?", and "Do you think your wife will like me". He then confessed that he had quietly taken my picture on his phone while we were drinking and sent to his wife. He continued that for the last 6 months, his wife's fantasy was to play with another guy....but someone who is raw and inexperience and at the same time with fit body and decent looking. Those times were the peak of my training days at the gym and I had recently joined a gym in Parrammatta. He added that he had offered to get some nice looking male escort from the area but his wife was not interested. Deep inside, I was telling myself "Wow what a jackpot that night!". As soon as I agreed to take his offer, within 15 minutes we were already driving back to his place in Epping. He notice that I was fidgeting in the car and appeared to be nervous. He tried to calm me down, "My wife already had some ecstasy" so she will be very horny and eager to meet you.
We were greeted at the door by his wife wearing a sexy, laced white underwear. He introduced me to his wife and said "I think I got what we had been looking for honey ". I felt a bit flattered. His wife motioned me to come to their masters bedroom and whispered "be quiet the kids were asleep at the room upstairs".
She then asked me to take off my clothes. I decided to keep my undies for a start and offered to give her a nice relaxing massage in the bed. While massaging her lower back, I got the hardest boner and was intentionally pressing it on her very sexy ass. She then asked me to take off my underwear and motioned me to stand at the side of the bed so that she could suck my throbbing cock with some precums flowing while James was watching. It was rather an intense experience as it was my first time to be sucked by a girl while her hubby was watching and stroking his huge German 8 inch size cock. But having an exhibitionist streak, I got more turned on...
James then asked me to put a condom and fuck Sarah in doggie position. He added, "fuck her hard!". And so I did, but got so carried away that James told me "not that hard mate!". After some nice doggie fucking, Sarah asked me to lay down on the bed she straddled and ride on my cock. It was then that James joined in by fucking her in the ass as Sarah was riding me. I thought I had only seen that scene in porno movies with double penetration and that time I was actually doing it with this young hot couple. After some steamy fucking for 1 1/2 hours, and lots of loud moaning from Sarah, I was pretty exhausted and rested on the bed for a while and closed my eye trying to catch my breath. .
I felt that she wanted more....she started licking my balls, and her tongue slowly going up to the shaft of my cock until my cock was again throbbing hard in her warm mouth. I was enjoying every moment of it when suddenly I realised that there was another mouth sucking my cock while Sarah was licking my balls. I opened my eyes and was shocked that it was James sucking my hard cock. I freaked out initially when Sarah said, "Relax, this is part of the deal". " You will play with both of us". I tried to settle down and just closed my eyes and relax again ...and I felt James actually sucked my cock better than Sarah. He even deep throated my cock...
As soon as Sarah noted that my cock is very hard and ready to fuck again, she said "put a condom on, and fuck James in the ass while he is fucking me doggie". "What?very dominant " I initially refused. But felt complied to follow Sarah's instruction. James squeeze in some lube on my cock and started fucking her in doggie position. I need to get the right rhythm so that I was fucking James in the ass while he was fucking Sarah. My first experience to fuck a guy. It was different, rather tighter hole. Took me a while to put my hard dick into James hole. It was another 30 minutes of fucking.
Later on, James continued to suck my cock as he had noted I enjoyed it earlier. And then, time to go home, Sarah was behaving funny. She might have noted that James was becoming more into me than her. James told me, its time to drive me back to the Irish pub. On our way back to Parrammata, James pulled over on the side of the highway and told me "go at the backseat baby, I noticed you did not blow on the second rounds and Im gonna finish you off". He then feasted on my hard cock at the back of the car . The highway was dark but early that morning a few cars were passing by and there was a thrill of actually being seen while having a blow job at the back seat. I blew again and James swallowed all of it.
I told this sexcapades to my brother overseas but omitted the part that James played with me as well. My brothers from Manila, told me "you lucky bastard". Deep inside, I told myself, yeah I was really lucky.
Looking back, after that experience, I then joined AMM, and this bi experience pave way to more experiences of of playing with couples from AMM. And happy couples I had played with further introduced to me to other couples ...
