The weather had been gloriously high summer for the last couple of weeks, making a mid-August visit to the lake earlier in the morning warmly enjoyable, especially in combination with the likelihood of no one else being around as we enjoyed ourselves naked in the water and on the shore.
A point that had been noted the day before by my bi-friend when talking to her now 9 month old girlfriend, as we were preparing to leave at the end of another wonderfully hot day. A point based on previous mutual experience on our part, actually. Kathy has been swimming here for two decades at this point, and I'm quite sure that the time we fucked was not the only time she had so enjoyed herself there. Especially as I had fingered her a couple times before and after that perfect summer day in the middle of the lake, fucking in the water.
Agreeing to meet early the next morning, the traditional the gin and tonic supplies were left to me to handle - the gin, glasses, nonmelting ice cubes and cool packs stored in a subzero freezer overnight, with limes and a couple of plastic bottles of tonic water in the refrigerator.
Arriving at almost the same time, we quickly unpacked, distributing the supplies to carry, and I put my helmet and jacket in the bike's bags. We walked a couple of hundred yards along the packed earth path, with forest to our left and brush and grassy areas to our right. We continued into the essential middle of the nudist area, this summer's favored spot - a nice mix of sun and shade, with a fairly narrow but well maintained entrance to the water, with a broad sloping cove opening up to the rest of the lake. The spot could easily hold a dozen people, with a basically private character, without any direct lines of sight from the paths, both along the shore, cutting through the brush, and from the vehicle sized unrutted path that ran along the lake on that side.
The ground was untypically dry as we spread out our towels, a welcome indication of the sort of summer day we had before us, full of warm sun and cool water. We undressed quickly, wearing minimal clothes as we were - though I was still wearing motorcycle boots. Diana was wearing a fairly clinging cotton top with thin straps, sunglasses, loose hair, a pair of jeans, espadrille style cotton shoes, with simple pair of comfortable black cotton panties.
Kathy was wearing a fairly short skirt and a fairly thin, half unbuttoned top, without sleeves. We do have slightly different styles when undressing, as I generally take off my pants, then my shirt. In contrast, both Diane and Kathy generally take off their tops first, something I always appreciate, as a braless woman in jeans or skirt is extremely attractive. Watching an unembarrassed woman take off her top right next to me is delightful, as I find breasts utterly wonderful.
Having two topless friends next to me as we undressed allowed me another opportunity to appreciate the differences between the two. Kathy's tits are heavy and full, with large and generally flat nipples. Nipples she loves having touched and nibbled, along with them being squeezed, sucked hard, or rubbed and held as she is fucked on her hands and knees. As she would gladly admit, or demonstrate, there is a fairly direct connection between her nipples and her erotic center, one she is quite proud of.
Kathy, in her later 30s, remains very proud of her breasts, which are often braless when she is being casual. Or shown off when she isn't being casual. Her creativity at showing them off is a well developed skill, something else she likes to be appreciated by others, at least in the proper contexts. It isn't quite about sex, and is something she knows will be different in the future, as she has more than occasionally remarked on, noting changes over the years.
Though some things remain the same on her part. Facing me, she unbuttoned and took off her thin shirt, then gave me a tiny grin, followed by turning a bit and grinning even more broadly to Diane, positioned at the third side of a 90° angled box shape - the missing side was towards the water, so in a sense, we were all screening each other from any casual view while being able to see how empty the lake shore in this stretch truly was.
I was already nude, and Diane had just about finished stepping out of her panties, her hand on my shoulder, head turned towards Kathy, who said 'remember last Friday?' then flounced her skirt quite teasingly. Her hands went to the top button, opening it, then she turned sideways to me, her gorgeous breasts hanging as she bent a bit more, and undid the next button, her skirt now loose enough for her to pull it up a bit, revealing pink and white panties around the bottom of her ass.
'No, those aren't...' I began, as she grinned, answering 'yes they are.' I looked briefly at Diane, almost chuckling, and back at Kathy, stepping out of her skirt, then did a slow full turn, providing a complete view of her well worn Hello Kitty panties. The same panties she had mentioned owning, while eating outside with my wife and I, her and Diane having come over to do a bit of grilling, in a discussion talking about Hello Kitty vibrators and how that brand had changed over the years.
A conversation which included Kathy's firm insistence that toys have no place in sex with her. Pretty much the same thing she had remarked a dozen years ago, after agreeing to test my coil vibrator for a night. When she handed it back to me, she said she came several times, but really, she wanted fucking or sucking when cumming, as another person keeps sex from being masturbation, something she considers inferior and vaguely shameful. Masturbation is a subject to be avoided in her eyes, though in the years since, getting off chatting online is something she finds worth her time.
