Not yet...

Just as she was about to let go, I pulled my fingers out, leaving her hanging. Sarah turned to me, a look of disbelief on her face. "Why did you stop?" she asked, her voice filled with frustration. "Because I'm in charge," I replied, grabbing her by the hips and pulling her close. "And I want to teach you a lesson."

With that, Sarah removed her bikini bottom, turned towards the diver, and began to give him a show. She spread her legs wide, exposing her wet pussy, and started to rub herself, moaning with pleasure. I watched her intently, the diver stroking his cock as he watched Sarah pleasure herself. It was an incredible sight, and I could feel myself getting close to cumming. I couldn't believe what I was seeing. Sarah was really putting on a show for a complete stranger. But at the same time, I couldn't deny that it was turning me on. I continued to watch as she brought herself closer and closer to orgasm while putting on a show for the diver. And then, finally, she let out a silent scream as she came, her body shaking with pleasure. The diver followed soon after, cumming hard as he watched her. The thrill of being caught in the act was a turn-on like no other. When Sarah came in front of the diver, I couldn't help but grin with satisfaction. Seeing her lose control like that was a sight to behold. Once Sarah put her bikini bottoms back on, the diver came up grasping for air after his orgasm. We knew that we had just given that diver the experience of a lifetime.

As we swam back towards the shore, I could feel Sarah's anger radiating off her like waves. She wasn't saying anything, but I knew she was furious with me for teasing her and stopping just as she was about to cum. I had thought it was all in good fun, but clearly, I had crossed a line. "I'm sorry," I said to her, trying to break the tension between us. Sarah scoffed. "Sorry isn't going to cut it, John. You teased me and stopped every time I got close. You'll pay for that." I tried to laugh it off, but I knew she was serious. "Oh, really? And how are you going to make me pay?" Sarah just grinned wickedly at me. "You'll see." I knew I had to do something to make it up to her, but I also knew that I couldn't let her get away with her teasing behavior.
