I went on a camping trip when I was 19. I was invited by a girl that lived in the same dorm as me and it was just her and I with three guys she knew somehow. Once we got to the campsite the boys set up a couple tents and then we all went swimming in the lake nearby. After swimming, we started a fire, cooked food, and started playing drinking games.
I never ended up changing out of my swimsuit or putting more clothes on so the more I drank the more confident I became. Some of the drinking games were getting competitive, causing us all to make bets that turned into dares. By the time the sun went down my friend was completely passed out and it was just me and the guys playing.
