My friend's girlfriend propositioned me on a camping trip

I was planning to go camping with a few close friends, but for some reason, my friend asked me to bring another woman, and we all felt uncomfortable. her, but she believes she is cheating on her best friend, who is suddenly out. In the camp, I was alone with my friend's girlfriend, whom I met for the first time. Yet it is the richest and most erotic space I have ever experienced.
