My wife flirting with and fucking a bigger guy at a nude beach

I want to beat a nude beach with my wife where everyone can see how hot her tight body is and how small my dick is. I want someone with a much bigger cock to approach us and her flirt with him. Eventually he’d point out how much bigger he is than me and she’d agree that she could use a real fucking. Everyone would see my little dick getting hard and eventually we’d go to a hotel where he’d fuck her in front of me while they laugh at how small I am.
