Don't like stories that includes women having sex with women? No need to keep reading
Though generally not mentioned, there is an overlap between nudists and swingers. Most nudists are surprisingly prudish when it comes to sex at designated nudist areas, understandably so considering how many non-nudists conflate nudism and sex. Swingers are considerably less concerned about the connection between swinging and nudity, but they are also a group that keeps their sexual activities to places where everyone else is also a swinger. Or at least swinger curious, so to speak.
Today I had brought an air mattress, inflating it using a battery powered air pump next to the motorcycle. This early, the lot was almost empty. Walking on the path from the parking lot, the need to deal with the blackberry bushes, even after having cut them back the day before, took up all of my attention. This summer had been very wet, causing their height and growth to be much higher than normal. Rounding the corner to the section, I concentrated on making sure the already inflated mattress did not snag any thorns. Explaining why the scene in front of me came as a total surprise.
Having stopped to make sure the raft did not snag, watching carefully as it swung, when finally looking at the section, I saw a woman on her hands and knees. Quickly realizing that she was sucking cock, large breasts hanging down, followed by noticing how she was being fingered, her pussy not quite exposed by my line of sight.
I just kept looking, the weed smoked earlier starting to captivate my cock, watching a married couple I recognized having sex. The way the section was laid out meant Charles and Alice were in a somewhat discrete area, reducing the risk of casual discovery. Unless they were too turned on to pay attention, or somebody swam by, as the view from the water was completely unobstructed.
This was not the very first time seeing a naked woman giving a blow job at the lake. That time, she did not stop as I walked past to the next section. Unlike that first time, today involved indulging my voyeur side. My cock was growing heavier under my jeans, and as it did, the feeling she was aware that someone was watching also grew temptingly.
Already knowing them as a couple made it easier to keep watching in a certain way. Normally, they were in the company of another woman. One about my height, bald pussy, a bit plump but also very feminine, and unusually for a nudist, quite devout. On the other hand, her various beliefs, sincere as they appeared, tended to be all over the place, not easily categorized into a single whole. That she was not here seemed to offer an explanation for what they were doing, unconcerned about having sex openly outdoors.
Seeing her head turn slightly, I realized that my hand was rubbing my downward pointing covered cock at the same time it became clear that she had seen me. Lifting her mouth away from her husband's erect length, she said "Join us."
Grinning, she then said I needed to get undressed to get head, looking directly at my crotch. For the very first time, I took off my clothes at this lake with an erection. Her husband was still on his back, eyes closed as he kept fingering her. After I finished undressing, she moved to straddle his face. Sighing, saying I should come closer, she reached out to grasp my rigid cock. As she guided me into her mouth, I looked at her swaying breasts, nipples displaying a female nudist's tan.
That being when a woman's nipples get as tanned as her breasts, so that there is only a minimal contrast in color, often making it difficult to recognize her aerola. Their friend was not as tanned, but she too had all round coloring, without her breasts being lighter than her exposed skin, highlighting the different skin tone of her nipples.
Alice's lips and tongue had a hypnotic effect, in part because of how turned on she was getting from having her pussy skillfully eaten. One reason 69 is so good is how each of you can feel the other sinking into pleasure, increasing your own as you increase each other's. Today, it was her husband making her provide such addictively slutty head, just as he had been fingering her earlier for the same likely reason.
Reaching down to feel her heavy breasts, she shifted position a bit, her sucking becoming even more lusciously uninhibited, moaning around my cock. Looking more closely, seeing how her husband had lifted his head a bit while she had moved back and down. "God yes, tongue her hot ass" I groaned, cock in heaven.
So much so that I could not stop when hearing a voice say "She does love that" from behind me. Turning my head, I saw their friend standing there in a thin cotton dress. The mouth left my jutting length, Alice saying "You were a bit late."
"Not that late" Sarah said, pulling her dress up and off, revealing that she had not been wearing any underwear. Plus revealing fairly erect nipples, making me wonder how long she had been watching our threesome. Looking between her thighs, Alice's hand moving over my slippery shaft, her inner lips looked more prominent than normal also. She noticed my attention, a hand briefly touching the top of her slit, saying "I was watching."
Stepping closer, arms open, pressing her smooth soft body against mine, lips near my ear said "Alice loves new cock." At which point Alice's lips slid over my cock head, tongue sliding over my sensitive slit. "Normally, they wait until we share a bottle first."
"A bottle" I was barely able to say, my ability to think disappearing in a haze of animal satisfaction, outdoors with three other naked horny people.
"We like to drink a bit before swinging" she replied. I could feel her large breasts against my back as one of her hands began to roam over my chest before some of her fingers concentrated on a nipple. After making me moan "that feels so fucking good," her other hand grasped mine, moving it between her legs.
