The pool is large. The lights are dim. It is dark out. But still. Surely someone will see her. My wife, her husband, somebody. Hopefully not.

She walks from the house to the side of the pool with such a beautiful predatory stalk. I cannot see her eyes at this distance, but I know in my heart that they gleam with lust.

She dives into the water the way a shark would, if sharks dove. She is gone. I cannot see her. But I know she is there, headed for me, focused on me, wanting my cock.

I reach down, freeing it from my swim suit, ready for her arrival, then put my elbows back on the edge of the pool, very calmly, and in the dark, I smile.

Her head breaks the surface like a tail fin, her dark hair wet and glistening. She flashes me a look that makes me even harder. I look around. Nobody is paying attention. Too dark. Too drunk. Too sensible to go near the pool inebriated, but she does not drink, and I am not trying to swim.

Down she goes again and oh my god. Her mouth is on my cock, underwater. I never cease to be amazed by her many talents. But even she must breathe. She is back up, beside me this time, panting, happy, smiling, kissing me, pulling me into her. Her suit straps are down around her arms and yes, her breasts are free, bobbing in the pool between us, and then pressed hard against me as I pull her even closer.

Still nobody has noticed.

Under the water my hands are on her firm ass, and then between her legs, pushing the fabric of the suit aside, strumming her clit, slipping inside her.

She takes it for a moment, then pulls my hands away. She stands in front of me holding my hands. I am disappointed. I want more. She knows I want more. Danger be damned. My cock is at attention, her cunt wants attention. She stares at me and then, still holding both hands, does a little hop so that her feet are planted on either side of me against the wall of the pool.

I cannot believe her audacity or the unobservance of those around us, but I cannot help now but participate, and pull her in, until hip is against hip, cock is against cunt, until she wriggles and bears down? sideways? toward me anyway, as my hips thrust out from the wall and I pull her in gasping.

I am insider her. In a swimming pool. At a party. With our spouses. It is way too much to contemplate, and I am not in a contemplative mood. I am in a fucking mood. I am fucking. She pushes out four or five inches against the soles of her feet, and then with our clasped hands I pull her back in. Her head is thrown back like she is ready to take off in backstroke race, but again she pushes out just enough and lets me guide her back in, my cock sliding in and out of her under water, pulling in, pushing out, pulling in, pushing out, faster and faster. We are both going to come very soon.

I am still paying attention to the other people. Not as much as I was, but enough to see my wife detach herself from a conversation and look around, probably for me. It is too late to stop. "Hurry," I hiss, "She's coming. "

"Yesssssss," she hisses back, "So am I!" And so am I. I can feel it rising in the tips of my underwater toes, up the backs of my legs to my feeble, wife-watching, about to explode, OH MY GOD brain.

That pushes her over the edge. She is trembling and jerking and moaning and gone and my wife is walking purposefully now down the side of the pool, unable in the dark to see quite what is happening, to see this wonderful beautiful long lithe naked woman kissing me deeply and then pushing off into that backstroke race, her race with time and danger.

My wife arrives as she surfaces at the other end of the pool, her suit straps quite properly back on her shoulders. Sure now that it is me, my wife waves, and smiles, and asks me if I'm enjoying myself. I smile at her and answer affirmatively, a little wistfully, before sticking my cock back in my suit and climbing out to join her.
