My girlfriend and I went to a party on a mountain top in Peru. We got high and danced for hours. When we decided to leave a guy we were with offered to help me carry her down because she was kind of wasted. She put her arms around our necks and we made our way down slowly. When we got back to the hostel we lay her down on the bed and she leant in and kissed the guy right in front of me. She then pulled me in and kissed me too. We ended up taking it in turns to kiss her while we slowly took off her clothes. It was so, so hot. After a lot of kissing, she ended up naked. Our hands explored her beautiful body. She started to moan. We put her hands down his trousers, grabbed his c*** and asked him to f*** her. I almost came just hearing her say those words. We got on top of her and I watched with bated breath as he put his d*** into her. They f***** for a few minutes then he came inside her p**** with no condom. He collapsed next to her but she wasn't done. It was mine turn next. It felt weird but kind of hot to f*** her dripping wet p**** that was full of c**. He watched for a minute until he got hard again. Then he tried putting his c*** in her at the same time from behind but it didn't fit. To my amazement she told him to f*** her in the ass instead. I tried desperately not to unleash my load. It was hard but we managed to double penetrate her. We all came at the same time. It was amazing feeling her p**** tighten and his c*** spew sperm into her ass. It was the weirdest experience of my life but I'll never regret it.
