One of the times I most enjoy visiting a sauna is when it snows. Sitting outside in the middle of winter in a warm pool watching the snow fall after being inside a hot sauna is wonderful. Often, the sauna is fairly empty on such days, allowing for the feeling of just being alone naked on a winter day. Not precisely the opposite of being alone on a nude beach, even if both are entrancingly sensual. The winter offers a more extreme contrast between the warmth of the water and the temperature of the air, and there is no warmth in the sky when it is snowing.
Following the 95°C hut 'infusion' session, sitting outside in the pool with just a couple of other people, I was surprised to see a pair walk by, one woman in a towel and bathing suit, the other naked, towel over her shoulders. Seeing a variety of naked bodies is a true attraction of the sauna, but normally it is not polite to concentrate attention on strangers. However, the naked woman was familiar, being a longer term visitor at a local nude lake. She looked over at the pool, smiling as she saw me.
We had not seen each other much over the past several years, but I certainly enjoyed comparing my recollections of how Ellen's large nippled breasts moved as she walked with the actual sight now. Recognizing Ellen meant being able to look at her lovely naked body without being rude. Especially a lovely full bush, something rarely seen, and only then in the spring at the lake. The person she was with was unknown, plus the fact she was wrapped in a fluffy large towel meant there was little to see. The straps of a bathing suit were visible, a bit surprisingly.
There has been a recent change to the rules meaning bathing suits are allowed in all pools, but when walking or sitting, the bathing suit has to remain covered. In the past, nudity was mandatory everywhere, though towels and bathrobes were completely acceptable when walking or lounging. Much like at the nude lake though, a bathing suit stands out in a place where nudity remains mandatory in different saunas.
As the person she was with continued walking, Ellen moved her head to indicate where they were going, a smile suggesting that I should head the same way too. Since we were not strangers, any doubts concerning mixed signals were easily dismissed.
The light snow meant that a towel over my shoulders was preferable to carrying it in front of me as usual, looking much like Ellen. Seeing how they went into the small cafe between a stainless steel pool and Finnish sauna, I decided to enter too. The grilled paninis are quite good, particularly when combined with a dark bock beer. Once inside, I saw one couple, both nude, sitting and chatting quietly at a middle table.
Ellen and the other woman were ordering wine and salads, then went to sit down in a corner booth. I ordered and waited for the sandwich to be finished. Turning with my plate and beer, Ellen waved, so I walked over. She made introductions, sitting between us, telling me her friend's name was Sue, and that they used to be coworkers. This did not lead to much further discussion into the past, but both seemed to have been unattached for a while.
I had not finished when Sue went to use the bathroom on the other side of the pool. Ellen asked about a lesbian/bi pair I knew, also regular lake visitors, saying she was curious about Lisa and Helen. After a pause, she added being curious about Sue too, asking for an opinion. Not trying to dodge exactly, starting out by saying that wearing a bathing suit was a tiny bit jarring and that was about it, having literally just met.
The other thing a bit jarring, though also intriguing, was how her leg started touching mine. This sort of first contact is always exciting, and like her greeting smile, something suggesting her mood was not quite the same as customary when swimming at the nude lake with other people around.
Ellen mentioned that one thing to know is that it had taken a while to finally successfully invite her friend here, the bathing suit rule making the difference. Sue knew that Ellen was a nudist, but had never done anything like that, one reason Ellen had never invited her to the lake. Making me laugh a bit, as Lisa hated a wet bathing suit with a passion and never avoided being naked. Making Ellen grin, saying that Lisa enjoyed showing off her body, to which I grinned back, sharing the same appreciation of that fact.
Leading Ellen to observe that Lisa rarely wore a bra. Which was true, but her noticing surprised me a bit, especially when she further mentioned that big breasted women like Lisa almost always wear bras instead of showing their breasts off like she did. Her foot slid over mine as she asked if I had ever noticed? Looking at Ellen's breasts for a brief moment, I lifted my head to say noticing lovely braless breasts was always fun.
Continuing on the subject regarding swim wear, we agreed that wearing something when everyone else was naked could be awkward. Chuckling, saying she hoped that Sue being naked was not going to awkward when we went into the large Finnish sauna. Not on my part, remarking being curious is nice, especially when such curiosity is satisfied.
Mine hasn't been really, Ellen explained, a certain expression suggesting she really had been looking forward to it. Sue had stayed on the other side of the dressing room, not looking at her at all. I knew what she meant, as there were lockers on the facing walls, with several flat wooden benches dividing the space. Basically, it was possible to dress/undress in such a way that any sight of exposed skin was fleeting.
By now, legs comfortably pressing, the thought arose that this was possibly part of a plan, her pleased to having me play a role to set her friend at ease. Or to at least make Sue believe Ellen had no specific goals by offering the company of a naked man also. One who could be expected to be familiar enough dealing in a social setting with a just met woman to at least not be embarrassing.
Sue returned and stopped near the counter, as if on the verge of ordering another glass of wine. We stood and walked to her, Ellen explaining good humoredly when meeting Sue that another glass of wine would not be the best idea in the heat. We held our towels loosely, quite exposed, something Sue noticed in a way that she might have done her best to ignore before drinking that first glass of wine.
Hanging up my towel, glancing at Sue starting to take off her suit in the vestibule area, Ellen standing near her, looking intently. She undressed in much the same fashion as in the dressing room, but Ellen had anticipated this. What she likely did not anticipate is how Sue took the suit off under the towel, remaining fairly covered as we went inside the pine log building. It was a humidly warm 70°C, and empty. Though this was the only sauna where chatting is not only allowed but encouraged, conversation is easier when not shared among several strangers.
Sue sat on the middle tier, with me sitting to her left. Ellen spread out her towel to the right, then lay down, head near the middle of the bench, one foot on her towel and the other on the wooden floor. Providing a great beaver shot, one I could not resist looking at. Not only because of how sexy she looked, but because Sue still had her towel closed.
Sue glanced very quickly towards me, seeing that I was uncovered, then focused on Ellen. After turning her head, it was a surprise to see her right hand slipping under the towel. Obviously, she could not resist looking directly at her friend's close at hand exposed pussy, one starting to show certain signs of what was occurring with Ellen. My cock was still under control, the swelling feeling delightful nonetheless. One of the advantages of having already seen Ellen's pussy was that it allowed the chance to make a comparison to how it looked now.
Ellen slid a hand over her bush, palm moving gently over the curly hair. This may not have been quite what Ellen had expected, but watching Sue's hand rise and hearing her sigh, it occurred to me that this may have been what Sue imagined. Not wrongly, as this was definitely the sort of non-explicit sexual play that could be done at the sauna.
Further, this was not the first time encountering this dynamic between two women. Several years ago, there had been a female couple, one always wearing a bathrobe except in a sauna. However, as time went on, she became less concerned. The bathrobe still covered her, but no longer so tightly wrapped, until by the end of my visit, they were passionately kissing naked under a shower's wet stream of water, the formerly shy one no longer able to resist the situation, body moving sensuously over her partner, hands fondling and pressing against the other woman's ass cheeks. A most definitely not shy tongue was clearly in her partner's mouth, and the way their nipples rubbed as their breasts pressed was delightful.
Ellen lazily mentioned Lisa and Helen again, saying she had not seen them last summer. I said they did not go as often, adding that over the years, there had been something of a reversal. Lisa had introduced me to nude swimming, and she used to go as often as possible. Sue was still looking intently between Ellen's legs, without noticeable motion of her arm or towel. Deciding to provide a bit of advice for a potential novice nude swimmer, I remarked that Lisa had not gotten a sun burn since Helen was with her.
