I admired my wife as she lay on the lounger in the sun. Her black bikini, while not super revealing, nevertheless hugged her curves and showed off her sexy body. At 37, she still looked as amazing as she did the day I met her 10 years earlier. Her perky B cup tits were covered by small black triangles of fabric. And her curvy ass was attempting to eat a black bottom that was rapidly turning into a thong. She smiled as she saw me staring at her and winked at me. With that, she got up and began sauntering towards the water. I stared at her ass as she walked into the water. 

I quickly got up and followed her, and we both happily swam out into the warm water. It didn’t take long for us to be in water too deep for Jessie to stand, but not too deep for myself. I pulled her to me, and we began to make out as I held her and she wrapped her legs around my waist, straddling me. We laughed as we kissed and enjoyed the sun, letting it warm us as the waves lapped around our bodies. 

We continued to make out and I felt my cock grow in my shorts as she ground her crotch against me. She reached down and began to rub my cock through my bathing suit as I grew harder. Her hands knew how to make me feel good, and she wasn’t holding back. This wasn’t like her, this sudden daring in public. But I wasn’t going to argue, I was going to enjoy this while it lasted. I began to head towards deeper water away from the beach and the people scattered tanning there. 

I had walked us out fairly deep and we were the only two out this far. Jessie pulled her lips away from me and looked around, then steered me so that her back was to the beach. With that done, she reached up and pulled her bikini top to the sides, exposing her perky and now hard hard nipples to me. I reach up and tweak her nipples while she continues to rub my cock. Her light pink nipples looked beautiful in the tropical sun. I couldn’t resist and bent my head down to lick them. Salty and firm in my mouth, I enjoyed licking her chest. 

I heard her moan softly as my tongue circled her nipples, and I knew what I was turning her on. This was so unexpected from her. Hell, even just the making out and over the pants hand job was unexpected, this was outside of my wildest dreams. I continued to enjoy her tits as her moans grew more urgent and her grip on my shoulders tightened.

She moved my hands back down to her ass as she reached both hands in between us to pull my shorts down and set my cock free. She stroked me and continued to grind against me while I had two handfuls of supple ass. She kissed me again, deeply, our tongues dancing. I needed her and she needed me. I could feel her grinding her pussy against my cock, only the thin fabric of her bikini bottom separating us from what we both wanted, and needed. 

She pulled her bikini bottoms to the side, and slid me into her. I was fully inside her in one thrust. She slowly lowered down on my cock, trying not to make what we were doing too obvious. She was using her pussy to grip me, and I was slowly sliding in and out of her, enjoying the tight sensation. We were both slowly enjoying the sensation when suddenly we both felt it together. The sensation of being watched. We both looked over to see a man, maybe 10 years older than us, watching intently while he stroked his cock.

Jessie looked me in the eyes and kissed me and slightly sped up her grinding. Then she leaned back, supported by her legs around me and my arms, so that our mystery man could get a view of her tits. He began jerking harder and I began thrusting with more urgency. He slowly walked closer, and through the surface of the water we could see his hard cock as he stroked it.

We had never fantasized about anything remotely close to a situation like this, and I was shocked at the display Jessie was putting on. She barely even like to wear low cut tops at home, but here she was riding my cock and showing a stranger her tits so he could jerk off. And he couldn’t take his eyes off her as he got closer. I began to wonder if he expected to join in or would be content with just watching.

I felt the grip of Jessie’s pussy get tighter as she watched this stranger jerk his cock to her fucking me. A low moan escaped her lips, the only sound any of us had made so far. Jessie was getting close and all three of us knew it. It didn’t take long for us to hear him grunt and see his hips thrust forward. He was cumming. He looked Jessie right in the eye as his cock spurted into the ocean, cumming hard for the sight of my wife grinding on my cock. 

At the sight of this Jessie kissed me and ground down hard on my cock, squeezing me with her pussy. I lost control and unloaded inside her. I thrust deeply as my cum filled her pussy. We kissed deeply as we both came down from our orgasms. When we looked over, our audience was swimming away. Jessie fixed her top and tucked my cock back in my shorts. She kissed me again and grinned and blushed. We both swam back to the beach and we went back to our chairs. 

We never saw our audience again.
