Hey everyone,

last night was really hot. We hosted a little house party with lots of booze and dancing. It was a great night with wonderful people. Around 2 am almost everyone had left except for one of our friends. He’s really more one of my gfs friend, but anyway. So, my gf came to me and asked me if he could spend the night. I wasn’t sure yet what that was supposed to mean, so I asked her whether she liked the guy and she said and yes and I also asked her whether she had slept with him and she also said yes. The thing is we have an open relationship and my gf sees other men from time to time and surprisingly for many, I think this is really hot and support her in fulfilling her sexual desires. I still didn’t know whether that meant that she wanted to have sex with him or that he really just needed a place to crash. We just prepared a mattress for him on the floor next to our bed and we all went to sleep. I thought nothing was going to happen but at one point during the night I woke up and noticed that my gf wasn’t sleeping next to me anymore. I looked down and there she was next to her friend cuddling. My heart was pounding so fast. I didn’t dare to move a muscle or make any noise and then I heard them. They were kissing. It was the unmistakable noise of lips touching and tongues melting. They were really making out right next to me! As they got more and more into the heat there was a lot of rustling and bustling. The kissing got more passionate and suddenly I heard my gf give out a sigh of arousal. I assumed he was touching her and caressing her under the blanket. I stared at them transfixed but also super turned on, my cock was hard as a rock. He proceeded to take of her nightshirt and then her panties! He also got rid of his boxers and I knew they were completely naked together under the blanket. The They kept kissing and embracing and touching for what felt at least 20min. Their breaths were going really loud at that point. Then, he got a condom and put it on his cock. I could see his erection when he removed the blanket, it was beautiful. I could also my gf completely naked embracing him, kissing him and pulling him on top of her. There was just enough light for me to see the moment he went inside of her, she let out a muffled moan, it was so hot, I thought I‘d burst. They proceeded to fuck first slowly and carefully and then more and more passionately. My gf was panting, I heard her say „oh my god“, I think she came right after. She came on his cock right next to me. He must have come soon thereafter cause they went still. They kept lying there in a deep embrace and kissing for another 20min until she slid out from under covers and lay down next to me again. She spooned me and cuddled me, kissing my neck and was really sweet. „That was very hot“ I whispered, „did you enjoy it?“ she nodded sleepily „oh yes“ she noticed how turned on I was and started to kiss me. She wrapped her hand around my hard cock and stroked it until I came all over her staring into her eyes that had just been wide from the pleasure she experienced. The next morning we all had breakfast together and she sent him home with.a kiss and a promise to do that again sometime.
