I was out camping with three guys and shared a tent with one of them. There was supposed to be another girl but she flaked on us. It was almost midnight when we were all back in our tents hoping to get a good nights sleep so we can head out on our hike early the next morning. That’s when we started hearing moans coming from another campsite. It got louder and more obvious over time. Someone was having some amazing sex.
Our friends in the other tent clearly heard it too, and texted us in a group text, teasingly asking if it was us. I was already extremely horny and wet, and the text called out the elephant in the room. The guy I shared the tent with responded back “i’ll bet you perves wish we were”. He then gave a nervous chuckle and said to me “she sure sounds like she’s having fun.” I awkwardly responded “the time of her life.” At this point we were both laying next to each other in this 2-person tent in our sleeping bags. He then turned away from me and said “goodnight”. About 5-10 minutes pass as we laid there to the sounds of this woman’s fast-slow-fast moaning, with a few long grunts sprinkled in.
