[MFM] First time ever sharing my girlfriend with the best friend.

Hi there, new here( had to create another account so it could be secret lol). A little context. I’ve been with my gf since high school almost 10 years now. Time is flying. We love sex when we have it, although it’s not as often because we both work all the time. My girlfriend let’s call her A, she loves attention though, it’s been hot out in NJ and on the weekends we go over to my dads pool. With the heat wave the water would be HOT, and the weather humid and perfect outside. The weekends are for drinking, my girlfriend has 34DD titties and they are amazing. To play with, touch, look at you name it. My best friend let’s call him, C. Comes over to hangout also. We’ve been weekend chillin all summer but this happened probably end of July. He’s always looking at her as she gets in and out of the pool. He also has had bad luck with girls, getting strung along for months on months by this one girl. So he is deprived. None of this was planned it sort of just happened. ~~~~ Thanks alcohol. Lol. Okay the good stuff. A was wearing a very revealing top. He could not stop commenting on it. The entire night we are downing glasses of alcohol. So we are all drunk by this time and it’s 3am I think by this time. My girlfriend complained about being hot so I said just take your bathing suit off. Which she replied “okay” and she got right out of her bikini and there was just a naked goddess swimming around in front of us. She would swim around and do flips in the water and then just pop up and lay on a raft stomach down so her booty was in the air. C just kept saying “your so lucky dude” over and over again. You could tell he was getting worked up. Then my girlfriend sits on the ladder with her boobs out and he’s just jaw dropped by this time. I started feeling them, and asked him “do you want to feel?” He asked A “can I?” I said sure, and he felt one and then the other. While we’re also talking about random sex stuff that night. I was also a little nervous because I never let anyone do that before, but there was some sort of rush… after a few minutes I said something along the lines of “ A get out of the pool and go on the grass, I want that booty on the ground “ “ she replied “are you sure?” Of course I said. My friend was a little confused. I said she’s going to give us both a handjob. (That’s what I was comfy with) so A got out and we followed her naked self to the side of the house. C said he was rock hard so I said take it out. A took my hard cock in her mouth and started sucking me off and jerking C off. You could tell she was liking it. She turned more to focus on C and he was playing with her boobs at the same time. I was standing there jerking off so I decided to get down behind her. She was dripping wet, i took some of her wetness and spread it between her boobs. I said to titty fuck her. C started pumping away between her boobs while I slid right into her, he was moaning in pleasure a little( fun fact any girl he’s been with had small boobs.) A was also moaning in pleasure from being used from both sides. I ended up shooting my load all over her ass after 5 minutes from it being so hot to actually share my girlfriend. Once I finished my girlfriend laid down and let him on top to finish titty fucking her . He blasted all over her boobs and face. It was dark so I didn’t really get to see that sight haha. Once we were done she got a towel and cleaned off. C headed home all satisfied. I’d say I’m a good friend:p
Drove home and fucked my girlfriend again. The next day we had to have fucked at least 5 times, the most we ever have in one day. A few weeks later we were all hanging out again In the pool, that’s a story for another time. Have any of you ever had an encounter like that? Let me know what you thought! I think it awakened something in me lol
