(Complete fantasy based on bits of reality)
This late in the season, the local nude lake can be empty even when the sun shines in a clear blue sky on a warm day. A woman a decade older than me was almost ready to walk from her parked car to our normal section when I parked my motorcycle. Earlier in the season her car had had an electrical problem, stalling in the gravel lot. I had helped her out, though there was nothing I could determine or fix. Pushing it into a luckily empty spot was the temporary solution. She had been quite grateful, almost too much so, as it was the sort of thing I do normally. Helping out is not much of a problem, especially when making it easy for me to leave instead of creating a traffic mess in the crowded parking lot as more people arrived.
Walking along the path, we chatted about how unusual the weather was, her remarking how empty the parking lot had been compared to when I had helped her. We set our blankets down on drier than expected grass. I undressed as she stood in the sun for a bit, looking at her as she took off her white t-shirt, with her customary blue bikini top underneath it. With familiar people, no need to look away as they dress or undress at a nudist area.
As we kept talking, there was mention of kids and how she was happy to not worry about them, then saying something about my wife and own kids. Explaining I was divorced, she said she knew. Then asked, straightforwardly, what had happened, something I have not really told anyone this way. Following on the discussion's path, I said a good part of it involved her wanting a third child, something completely against my wishes. Leading to some strange distortions involving sex that grew worse.
Taking off her top facing me, seeing how her well tanned breasts appeared in the light, intrigued as always by their lovely fullness, and the way her nipples pointed somewhat downwards. The sight of a topless woman in jeans is something that I always find sexy, and starting to talk about the past involving my love life made me quite aware of having an exposed cock. Asking what distortions meant, she sat down to take off her jeans, still facing me. I explained how my ex wife had insisted, a couple of years after having a second child, that the only sex she would have with me meant unprotected sex, especially at the peak of her cycle.
I kept looking between her open legs, seeing a bit of hair on the sides of her bikini bottom. Her undressing was nothing new, knowing that she did not shave between her legs, something I always appreciated seeing. Having started to talk about marital details, a certain temptation kept growing while speaking and looking. Something that became a minor issue, my cock starting to twitch subtly. Telling her another thing that divided us was her wanting to shave her sexy bush, looking like a girl, not a wife.
You like a woman's bush she said, I have noticed how you like seeing mine. Explaining to a degree the way her undressing had seemed more inviting than usual. The reaction those words caused was less subtle, though I tried to remain matter of fact, saying she did have a pretty bush, and that unshaved women were rare compared to a couple of decades ago. Her smile, after glancing at my cock, confirmed she knew that I was not lying, but not saying everything.
Soon getting into ever more private marital details, revealing how hot fucking my ex wife had been at the peak of her cycle, though with cumming not an option. Being inside my wife, even with how wonderfully natural it felt, was taking a chance that needed to be avoided. Sex can be hard to resist, but that can happen when it is no longer something shared, just a contest at which a winner and a loser play. This is condensed, as the conversation was considerably more drawn out and more oblique at its start.
Taking off the bottoms, she said she could understand how frustrating sex like that might be, waiting to see if the next period skipped after fucking at the best, or worst, time. Looking between her open legs, her labia looked a bit larger and darker than normal, much the same way my cock was larger than normal, at an angle she had never seen before. This discussion was clearly interesting to both of us, in a thoroughly adult way. With no one around, we could keep discussing married sex and not having children.
Causing me to mention that waiting had happened with several different women, including the very first time using a latex condom, which broke. She was curious, and by now, my cock was happy to be involved in talking this way with a naked older woman I'd always considered attractive.
Telling her how that happened with my first girlfriend, fucking like normal when not on the pill - which meant really good sex with condoms. We had never really used latex before, but the lambskin condoms we both preferred had grown rare. Knowing the condom was there as I fucked her from behind meant that when the sensations became utterly magical for both of us, we just kept going. The sudden wave of growing pleasure made thinking unnecessary as the fucking grew ever better. Only after we came, cock ramming and pumping cum deep inside her squeezing tunnel, then slowly separated did it became obvious that the condom had broken, creating a ring at the bottom of my shaft. A fact explaining why we had had such hot pounding sex. Also, providing a useful reminder of how fantastic unprotected sex is.
