It was a hot, lazy, summer’s afternoon.   The sort you spend doing as little as possible, or like me, in the pool.  I’m not much of a swimmer, but the kids wanted a splash, the heat was oppressive and there was Katy.  That would be Katy, wife of Jim, mother of two, turn-on of one – me.  Having her bob up and down, reaching for the ball, ducking under water… plenty of chances to admire her smooth body and full breasts.  Katy’s no supermodel, but she has a sensual way about her and a pretty face, which somehow make her much more attractive than many more classically beautiful women.  So I enjoyed nipples defined clearly against a bikini top, ample opportunities to admire barely restrained bosoms, and occasional sightings of long legs when she dived.  We’d known Katy and Jim for a few weeks, and I’d liked the look and company of Katy from the get-go.  Jim was as boring and bland as they come – if he was a food, he’d be a boiled potato – and I kind of got the impression Katy was a little frustrated with his lack of adventure.  It had been an effort to persuade him out onto this weekend away.

But none of that was in my mind as I was treated to a view of Katy surging out of the water to grab a high catch, breasts moving magnificently down, then up as she fell back into the pool. Fortunately my own bathers were loose enough to hide the evidence of my appreciation, and I had taken care never to come out of the water, so to speak.  I noticed another guy in the pool shooting the odd glance.  Why the hell not.  My own wife was out of the water in a chair, reading, as was Jim, so maybe he thought we were together.

Of course, even perfect afternoons need to end, and eventually we climbed out of the pool.  The kids had their clothing there, but Katy and I had left our clothes back at our shared house when we’d fetched the kids’ bathers earlier in the day.  So we left our partners to towel off the tired kiddies, and started on the five-minute walk back to the house, pleasantly bantering about our skills with the balls.

Of course, I was thinking about fucking her.  Had been all afternoon.  But I had no intention of doing so.  I’d take my own wife later on, good and proper.  Anyway, I could admire the view, as, even the gentleman, I let Katy go ahead and open the door.

“I’m going to have a shower before we head back,” she said as the key turned in the door.

“Me too,” I rejoined.

“Me first,” she declared as we moved towards the bathroom.

“No, me, I’ll be quicker.”

“No, I said it FIRST!”

“Hey, look what the cleaner left over there!” I pointed towards the curtains.

Momentarily distracted, Katy peered over in the direction I indicated, and I took advantage of the moment to sneak ahead
