I’ve had similar fantasies. My wife and I are camping. The evening before we spent some time at the neighbors site. Just having a drink and socializing. In the morning she makes her way to the showers. Unbeknownst to her, the guy in the next site follows her. My wife strips naked and gets in the shower stall. With the water running she can only faintly make out another person walked in. She thinks nothing of it. He strips down and gets into the stall with her. Her back is turned and assumes it’s me. When she turns she’s surprised to see him. But not disappointed. His big cock is hard and ready. My wife goes down on him. Then he stand her up and bends her over! He fucks her from behind!Hot sex in the showerhouse with another guy who “happens” to peek into my shower and ask to join…
When she gets back to our site she tells me everything. And they made arrangements to get together later. That night I can hear the moans, grunts and orgasms coming from his tent!
