My first swinging experience just happened last month. Let’s start by describing ourselves first. My girlfriend named Serene is an Asian girl with a middle tanned complexion and skinny frame. She is at 5ft 2 & weighs 38kg and has small petite breasts of 32A but very protruding nipples. When I first met her a year ago, her relationship with her then boyfriend was rocky and right before they broke up, they had a final sex. She told me she no longer had feelings for him and the final sex was just pure sex with no emotions but she did admit that it was really good as he banged her doggy style real hard and deep. Six months later we got together and our sex life kicked off actively where we have sex 4-5 days a week. She has been really honest with me about her past sex life and I am her 3rd sex partner. Her first partner named Andy really sucked at it and has a thin 4.5’ cock while my 6’ cock has an average thickness. She tells me the sex with me is awesome and she enjoys my cock size. I asked her about her 2nd partner named Jay and she told me his cock is marginally longer and thickness is about the same. Sometimes she gets me really horny, my cock gets really hard and I will bang her doggy style real hard and she will start saying things like “oh yes, fuck me, fuck me harder and deeper, oh yes that’s it, yar those spots, u r going to hit the spots”.... and she will be really very horny and bucks on me like trying to get my cock deeper. One day, she told me her last fuck with Jay was actually awesome as he was hitting deep spots with his longer cock and he just kept fucking her for nearly an hour before he came. Serene and both her ex’s are still friends and one day we all went for a same party at another friend’s place. We were actually quite drunk and some of the guests has left and only myself, Serene, Andy and his gf Jay and the host and his gf stayed back. We were all quite drunk and we started to play spin the bottle. We started off with drinking dares and slowly more funny dares. Then it went a bit more wild where the dares became more sexually charged. We now used poker cards to replace the bottle whereby the person who draws the highest card is the boss while the lowest card is the slave. Each person has also written in blank cards for secret dares. The first round began and I got the highest card while Andy’s gf got the lowest card. The dare card was for the boss to squeeze the slave’s breasts through the shirt, so I went for it and I must admit her boobs are really amazing and way bigger than Serene’s 32A, I later found out that it was 34C when the host had to remover Andy’s gf’s bra as part of the dare. As the game went on, Serene drew the highest card while the host drew the lowest card and the date was for the slave to rub the boss’s pussy through the knickers. It started off with lots of laughter and the host proceeded to to put his hand under Serene’s skirt and she playfully moaned and all of us just continued laughing. After a while, the moanings became louder and it seemed more real as if Serene was being fingered. After around 5 mins, she was shaking a lil with heavy breathing and it looks like she came, but I didn’t think much as it was the host was supposed to rub through her knickers. I could see the hosts hand moving more vigorously and her skirt came up a lil and all of us saw he had 3 fingers in her pussy. We all protested that he cheated as he wasn’t supposed to finger her. But he just replied “how am I supposed to just run her pussy over her knickers when she is wearing a g-string thong” and we all had to agree and we were quite drunk so we continued with the game. Fast forward, Serene gotten the highest card while myself, Host and Jay got the same lowest cards. Andy came up with a brilliant idea whereby Serene will feel each of our cocks and the one with the biggest cock gets to fuck her there. Serene took up the date and started to feel our cocks through our pants. I was a lil intimidated as Serene told me before that Jay had a slightly longer cock and I didn’t know how big was the host’s cock. Finally she announced, “ok, I have done my measurements”. She came to me and started to unbuckle my pants, I was thinking that maybe Jay’s cock was just slightly longer and she didn’t want to hurt me there. She whipped my cock out and everyone started cheering as if I had the biggest cock. Suddenly she looked at me and said, “honey, you are a lil smaller than both of them but I will blow u while the biggest gets me, don’t worry I just lost by a lil”. My heart sank straight away and she turned to the host and Jay and starts removing their pants. The host had a cock of 6.5’ and same thickness as mine and he thought he was the biggest. After that she removed Jay’s cock and to my horror, he is not slightly longer, he is way longer. I’m sure it was around 8’ and it was way thicker than mine. Now I understood what she meant when she said he fucked her real deep. Serene stood up and said “I guess Jay is the biggest so come and claim your dare but go slow as it’s been a while since I had your big cock”. She went down on all fours, took my cock in her mouth and wanked the host’s cock. Jay positioned his cock at her pussy and he slowly slid it in. She stopped sucking my cock as she slowly takes his big cock in her pussy. Jay starts thrusting and says “oh gosh, it’s been a while and I can’t remember your pussy being so tight”. Serene replies “I miss your big cock stretching my pussy, oh yes, fuck me deep, I miss those deep thrusts, come on, those spots, oh gosh I miss those spots”.... she keeps cumming and after around 30mins he announces he is about to cum and he pushes one final time and blows inside her, bare back. I can’t believe it because she will never allow me to cum in her. Jay tells me it’s ok as he had a vesectomy. After that everyone was so horny, Andy had sex with his go while the host was also shagging his gf. Jay fucked Serene a few more times and the only thing Serene didn’t lie was that Andy’s cock was really small. I fucked Andy’s gf and she was moaning like crazy but I’m the end, all of the girls was worshipping Jay as he fucked all of them really hard
