Only if you get him to show you his cock

"Only if you get him to show you his cock," you say, your own meat throbbing in your fist as you slowly pump, trying not to attract more attention on the beach than you already are. It's starting to fill up, and you don't want this game to stop, especially not the cops.

"Oooh, fuck I'm wet," your girlfriend mews. Even over the sound of music, the waves lapping at the shore, and the people on the beach, you still hear her fingers in her pussy as it gets wetter and wetter. You watch as she's getting closer to cumming and she pulls the triangles of fabric off her tits, her tight, dark nipples getting harder and crinkling as they stretched toward the sun. She licked her lips, looking right at the guy taking the most interest in her and started licking her lips like she was sucking his cock from across the sand.

He looked around, looked down as if he was trying to figure something out, and then fished his rod out of his board shorts.

"Mmmm, I bet that would feel amazing. His girlfriend's a lucky woman," your girlfriend cooed and looked at you. "Watch him for me, I can't," she said, her voice catching and she moved the soaked piece of fabric from her pussy, exposing her dripping twat to the sun, surrounded by dozens and dozens of people.

"Fuck this is amazing!" she whispered and bit your shoulder as she came a little.
