As I followed her into the spa she looked directly at my cock and said that this was the first time she had seen a penis other than her husband's. We sat in the spa beside each other a suitable distance apart and enjoyed the warmth. Her body was good, nice breasts and her mound and pubes were invitingly close under water. As much as I wanted to touch her, I was worried that someone could come in at any time. She asked me how I avoid getting an erection, and I laughed, saying 'I just think about something else'. She asked about my wife, and if we have sex with other people. I said, 'not generally'. My gaze kept returning to her crotch and, when my hand lightly brushed her thigh she noticeably quivered. She moved a little closer and reached for my cock, but I moved away, saying 'would you like to see my camp?' She told me her husband was due to pick her up soon, but yes, she thought she had enough time.
We dried off, and I got back into my clothes, relieved that I would not need to hide my erection, and she threw on her towelling poncho. The tension as we walked down the track to my campsite was unbearable. Her mobile phone rang, startling me. It was her husband. She said 'I'm walking back from the beach, see you in the car park in about 20 minutes'. When we reached my campsite she motioned to follow me into the tent. I stepped out of my jeans, quickly tidied my tent, sweeping away the used tissues from my morning masturbation, and as I turned and lay on my side she pushed me over on my back and straddled me, squashing my hardon against her pubes.
No need to take off her poncho, I had barely got my hands up inside it to cup her breasts when she reached down between her legs to guide my cock, which slipped into her already-wet pussy, and before I knew it she was fingering her clit and humping my cock like there was no tomorrow. I fondled her breasts and tweaked her nipples while I tried to control my cock but she clenched her cunt around me and spasmed before I had time to cum. Like nothing I had experienced with my wife, except one time, but that's another story. I was still hard, embedded to the hilt, as she lay down panting on top of me, her breasts squashed against my chest.
I put my arms around her, starting to hump her from underneath, and said, 'I'm going to cum'. She just said 'OK' and whimpered as the sound of my cock squelching in her cunt sent me over the edge and I came inside her, both of us breathing hard. There was no time to lie around, so I took her by the hand and we quickly showered in the communal showers before she set off down the track to the car park to join her husband, without looking back.
I did not see her again, but finished my book inspired by our brief meeting. The book has been rejected by several publishers and the unpublished manuscript is still sitting on my desk at home. My wife took some time off to join me a few days later, and as we made love in my tent she asked, 'Have you been using a new kind of soap?' I'm sure she noticed the woman's scent, but I said 'It must be the shampoo from the shower block', before I pushed my cock deep into her and came, thinking of that fleeting encounter.
