(As with all of these fictional stories, a number of real elements exist)
After spending three days away at a customer, after getting home I saw a note from my wife where I keep my helmet, that she would be back later in the evening. In the summer, it is quite typical for her to go swimming in the evening, when the lake can be quite empty, especially after an early afternoon storm.
Like yesterday, which was stormy, but cleared up gorgeously she had said when we last chatted, adding she really enjoyed herself, hoping that we would do the same after I got home. Going into the home office where the PC and laptop are kept, I noticed her phone still plugged into the PC, with another note. Saying to check the ashtray, discovering that she had left something hand rolled in a dish we occasionally use as an ashtray. I don't smoke tobacco, and she rarely smokes anything else, saying she hates the smell of weed.
Now wondering what was going on, with a certain growing pleasant suspicion that it would be delightful, since she knows how smoking a joint goes straight to my cock. Her phone has never been password protected, and after moving the mouse to get rid of the screensaver, the file manager was open. Clicking on the first JPG, I was not surprised to see it was taken at the lake, from yesterday.
What did surprise me was that it was a picture of Karen, a friend of ours. A nude picture taken by my wife, a sight that began making my cock swell. There was a bit of video of Karen turning and going into the water. Then several nude pictures of my wife, obviously taken by Karen, the last couple showing my wife's expression as her friend's hand slid between her legs. By now, things were starting to click a bit, rubbing the full length of a downward pointing cock.
They clicked even more when seeing the next several pictures, selfies taken as they held on to each other, their breasts touching, followed by easily a half dozen pictures of them kissing ever more passionately. With the joint now having its obviously intended enticing effect, joining them at the lake was irresistible. Nude swimming means needing nothing more than a towel, though I did bring the phone along too.
The bicycle ride is only a couple of kilometers, and after arriving it took little time to find the two together on the beach laying on their stomachs. It was Karen that first noticed me approaching, turning on her side, displaying her naked breasts and bush. My cock grew again, outlined under confining jeans. My wife lifted her head, and seeing my obvious condition, grinned at me, her hand moving to Karen's hip.
Even to me, saying that I brought the phone as a way to indicate I knew something was going on seemed unnecessary. It was Karen that answered, saying that it would be nice if I could handle the camera work today. A request that almost made me cum, cock bulging. After the first couple were taken, my wife also turned, her hand starting to move down and between Karen's legs, right in front of me. She knows I love the sight of a woman's bush, making her hand playing with Karen's dark blonde pubic hair an incredible sight.
"We wondered when you would get here - did you enjoy our pics? Really nice, right? Would you like a beer?" she asked in a bit of rush, even as her hand kept moving. Karen's eyes had fluttered closed, and hearing her low moans grow louder the closer I got was delightful. My wife taking the lead with me was a bit of a surprise, though seeing that several beer bottles were empty provided something of an explanation. If my favorite accessory to sex was weed, my wife's is definitely alcohol. A reason she actually avoids getting too drunk at times, not wanting to be too horny to stay under control. And a reason, like today, to drink more than normal, laying nude next to a close friend in public.
My wife has always been curious about women, and interested in Karen more than most. She is slender, smaller breasted and taller than my wife, generally wore her blonde hair loose, and dressed in a style my wife found attractively femme. Several months ago around Christmas, having dinner at a local restaurant with the choir they both sang in, after a good amount of drinking, things had gotten interesting between them. Though that time, it was Karen initiating things, both talking about what it would be like to kiss a woman and ever more obvious contact as her conversation grew more explicit about what women could enjoy with each other. Mainly on Karen's part at first, but my wife soon grew increasingly aroused by the attention, along with the wine she was drinking.
Attention which was not subtle, causing my wife to let out a few surprised gasps before moving away after Karen openly kissed her neck, one arm under the table. My wife has always been extremely reluctant to ever do anything sexual in public, in the sense of other people being around or seeing her get horny. Public in the sense of a public space and getting off is fortunately a different matter. She has cum on several occasions at a local mixed sauna in a small warm pool with water jets that she cannot resist spreading her legs in front of, giving in to the pulsing pleasure centered on her uncovered pussy.
Watching her cum always makes me hard, a bit embarrassing in any public space. Women can easily pretend they are not aroused compared to an erect man. Further, a man obviously should definitely not cum in a public pool. Nonetheless, both men and women enjoy the effect of a water jet between their legs, though typically, my wife finds it unacceptable when other people are around, especially when it is a man enjoying the sensations.
Today represented a definite expansion in her attitude. We have had sex here, but never with anyone else around, following the same privacy rules as at a sauna. Which do contain some leeway for discrete exhibitionistic and voyeuristic delights. My wife knows how to make me get horny at a sauna or nude lake as we both look at a person or couple, taking advantage of my weakness after looking at her naked, having me shift attention to look at another woman, asking what I like about someone else as she slides against me.
