I would probably question why you're walking around on the beach in high heels. That seems like a good way to get a twisted ankle
I'd probably stare at you from behind my sunglasses for a while, and when I noticed my wife notice me looking at you, would say some kind of unappreciative comment about your skimpy swimsuit or how you're going to get severely burned with that pale complexion. I will then try to be more subtle in staring at you admiring you.
Politely look the other way after getting a good enough glance to take it in. It's rude to stare.
See if you want something to cover you up with. Either my body or something sticky 😉. Thought the back looked good but the front is amazing!
I'd wait for you to lay down and then take a fat dump on your back, then lay down on it and make a sort of poop sandwhich with me and you as the bread
