My first group sex experience [MF]

A few years back when I was at uni I used to party with a big group of friends – sexy young people + music + substances led to a lot of hook ups and experimenting.
One weekend we’d been invited to stay at one of the group’s family homes which turned out to be a massive old mansion on a big plot of land. They even had their own barn which was bigger than most houses. The barn is where it all started…
We’d all had some drinks and danced a bunch but it was starting to get cold so we’d naturally started to sit together in a small circle and snuggle under some sleeping bags. I can’t remember exactly how it began but I remember a few people starting to make out. Before I could really register what was happening one of the girls faced me, gave me the sexiest look and came towards me with lips parted. Let’s call her Christina. I’d always fancied Christina but we’d always been dating other people so had never hooked up. We started kissing deeply and lost ourselves in the passion. When we looked up we saw others swapping partners so we turned to kiss our other friends. Another girl in the group (call her Laura) was close so I leaned in to kiss her and had another passionate kiss. Kissing different people in a short time frame was fun cus each kissed differently but all were great kissers.
At one point I looked up and was facing another guy in the group. I shrugged and asked if he wanted to kiss but he wasn’t as open to it. I’d had limited experience with other guys at the time but I wasn’t afraid of a little guy on guy fun (I’ve had bi experiences since but that’s another story). I could tell Christina was disappointed not to see us kiss as she had been encouraging us to do it. I wasn’t attracted to him but in the moment I would’ve gone with it.
Some people started pairing off and spreading out into other areas of the barn. Four of us stayed together in a group of 2 guys and 2 girls; me, Ben, Laura and Christina. We started to get cold so we headed into the house to Ben’s room. The house was huge and it would’ve been fun to explore and fuck in lots of rooms. Ben and Chris got onto his bed and dove under the covers while me and Laura stayed on the floor. I could hear the unmistakable sounds of foreplay coming from the bed as I undressed Laura and began to give her head. I started kissing her neck and licking her nipples before I worked my way down to her navel, teasing for a second before sliding my tongue down to her clit. I have a tongue piercing which everyone seems to love and Laura was no different. She was arching her back and moaning loudly as she got closer to climax and I was getting hard thinking about her cumming in my mouth. I heard Ben and Chris start to have sex and the covers had slipped off so they were partially exposed and Laura and I watched them for a bit as we played with eachother.
Then I turned back to Laura and she laid on her back ready for me to enter her. I gave one last kiss and lick on her pussy and then slid my dick slowly into her and started to pick up speed with every plunge, enjoying her moans as they got louder and louder. We fucked like this for a long time before we both came, realising how drunk we actually were. On the bed Ben was slamming Chris as hard as he possibly could to reach his orgasm and he came loudly and slumped to the side of Chris. Laura and I enjoyed the show and were playing with each other again and my semi was growing rapidly.
Laura and I were curious to hear how their sex was so we crawled still half clothed over to them. At the time I hadn’t realised I was bi but I did give Ben’s body a good look over before I turned my sights on Chris. I climbed under the covers with her and threw off the last bits of clothing I had on. We pressed our naked bodies together and kissed passionately. I got so turned on thinking about how we’d both just fucked the others and kissed my way down her body to her pussy. Ben had worn a condom so there was no cum leaking out of her so I began kissing and teasing her lips. My tongue bar hit something else metal and I realised she had a clit piercing which I found insanely sexy. I asked her about it and she told me about when she had it done and how it felt. We played with eachother for a bit as we watched Ben and Laura do the same on the floor but called it a night in the end as we were all exhausted and still a bit drunk.
The next morning their were some sheepish grins shared as we sat around the breakfast table. The others that had split up and paired off told us where they’d ended up and had sex and we told them about our night. I think everyone was a bit horny hearing all the stories.
Since this both Chris and Laura were in long term relationships for a few years so we haven’t hooked up since. They’ve broken up with their boyfs now so maybe we’ll get chance to play again. I’d love to have some bi fun with Chris and another guy.
