I first noticed him sitting in the Jacuzzi watching my wife as she swam lengths of the hotel pool. I couldn't honestly say I blamed him. If I say so myself she is a bit of a stunner. Blonde with a nice slim athletic body and small pert breasts. I guessed that, like me, he was kind of hoping that her very small bikini top would slip as she swam to reveal a glimpse of her breasts.
On that particular day we were both out of luck and everything stayed where it should. His bad luck was further compounded by the fact that within seconds of him going into the sauna she got out of the pool to go and sit in the Jacuzzi. I climbed in to join her and in no time her hand was grabbing the bulge in my trunks under cover of the bubbles. Returning the favour I eased her bottoms to one side and started to rub her exposed clit. She was starting to breathe much more heavily and force herself against my busy fingers when the timer switched off. I would have carried on regardless but she whispered in my ear that we should have a quick shower then head back up to our room. I was in no mood to turn down an offer like that, and on the basis that I didn't know anybody there, didn't even wait for my erection to subside before climbing out and heading for the changing rooms.
When I went into the shower area the guy from the Jacuzzi was in there. The showers were arranged on a communal basis with no separate cubicles, so I was a little surprised to see that his cock was semi erect as he rubbed shower gel into it. We nodded greetings at each other as I went and switched my shower on, and removed my trunks. My hard on from Sally's attentions had not completely subsided and as I looked up I saw that he was clearly looking at me from the corner of his eye.
For my part I couldn't help sneaking a surreptitious glance to see if he was still in a state of semi arousal. If anything he was even harder, and I looked away quickly, not wanting to get caught. I was a little disconcerted to find that my erection was growing as I felt a curious sense of unexpected and unwanted excitement at the position I found myself in. I tried to studiously avoid looking at him any more and almost managed, but I did notice that he was pretty much fully erect as he finished rinsing off and walked out of the shower area.
Feeling very uncomfortable about what had just happened I made sure that I took a very long time over finishing my shower. Even so I was still hard by the time I had plucked up the nerve to go and get dressed. To my relief he had gone and I dressed quickly to go and find Sally looking very impatient in the reception area of the health club. I apologised profusely and promised an explanation when we got up to our room.
Once in the room she sat on the bed with her arms folded. "Well? What was so important to leave me sat all turned on by myself?" I think she was teasing me with her sternness but felt it best to be conciliatory in any case.
"Well, did you notice that guy sat in the Jacuzzi while you were swimming?"
"What, the tall, slim good looking one? Absolutely not." Now I knew she was teasing.
"He was naked in the showers when I went in and he had a hard on, and then I took my trunks off and I had one too. So then I had to stay in the shower until he had finished dressing and left."
"So seeing another man's hard on gave you one?"
