For the last day of our vacation on Maui, my wife and I were soaking up the sun and enjoying the surf at Black Sand Beach near Hana. A few other people were on the small beach, mostly couples and some families with children. About 20 people in all, everyone naked.
The female partner of a twenty-something couple came over with her camera and asked us to help with taking vacation photos of the two of them. Of course! So we went to the edge of the rocks and took several shots. Most were full frontal nudes, standing or sitting, with their arms around each other. They explained that they were on their honeymoon. The full nude pictures were for themselves, but they also had us take several that hid their pubic areas and her breasts, by strategic placement of hands, legs, or the branches of the one small tree on the beach. These would be for showing to relatives, or, maybe to future children. My wife and I took turns with their camera, and after reviewing the dozen or so shots, they were satisfied, thanked us, and went back to their own towels.
Toward the end of the day, people started leaving, all except for four women. Once there were no children, the same couple came to us again and asked if we would take a few more photos, only these would be more daring. Sure; why not! We moved all our towels and gear to a more secluded cove, just around the rocks from the main beach. These poses were explicit: fingers inside her pussy, or her hand around his dick, or the tip of his dick just inside the lips of her pussy, doggy style and cowgirl position, forward and reverse. Him licking her, she taking him in her mouth. Some sixty-nine. No close-ups of body parts; just full-body with faces. Not fucking, but just barely penetrating if at all, and with both of them smiling at the camera. Then a few with it all the way in, each followed by one taken just at the moment his dick pulled away, to show her pussy still open, and their shared wetness. We did many retakes of this particular pose, until we finally got a shot showing a strand of fluid stretching between them. In that final photo, they are smiling (as in all the photos), but the shiny string of juices connecting them, along with their grins, really made this one the 'money shot'. My wife and I then took a short walk to the next cove to give the honeymooners time to take care of the sexual needs they had built up by posing.
Joining them again, we learned they were pleased with their pictures, so we handed them our camera so we'd have own special photos to take home.
Once our camera was turned on us, we just carried on they way we usually do at a nude beach: hugging, kissing, posing singly or together, lying on the sand, frolicking in the surf, climbing on the rocks. Lots of touching and some nipple play and ass grabbing. My wife has exceptionally long, prominent nipples, but today they seemed even more erect than usual. After we ran out of the usual tame poses, we went for more explicit:
Me kneeling behind her, looking out from between her legs. Or her with my soft dick resting on her face. Several imitating famous paintings. Some with her stretching her pussy lips into different shapes, to mimic the smile on her face. (Neither the young bride nor my wife was smooth shaven; each had a neatly-trimmed bush.) Some shots of us climbing the rocks, with the camera looking up from behind and below. In these, she's smiling back at the camera while her legs are wide open across the rocks, giving a nice view of the smooth underside of her pussy. (The similar view of me is not so appealing!)
In every picture, we're smiling at the camera or at each other, wearing only sandals and wedding rings, and sometimes hat or sunglasses.
After taking so many shots of us, the newly-weds suggested that maybe we'd like to have some photos of ourselves fucking. My wife and I agreed, but secretly decided to play a little game: we made them think that in our many years of marriage, we knew only a couple of positions, and they'd have to coach us through some additional ones to make the pictures more interesting. We would play dumb, and let them 'instruct' us.
They led us through several poses, not actively fucking as in stroking in and out, but rather putting it in and holding it there for the camera, then withdrawing and going on to some other position. (This photography was stills, not video, so no motion was needed.) We didn't really call this fucking; it was just arranging cock into pussy for the camera. Slide it in, click, slide it out. No humping. This was good, because although my wife got a few orgasms, I would have been good for only one or two and then be too soft for any additional 'instruction'.
When we got to reverse cowgirl, we kept making like my dick was slipping out, until finally, in frustration, the young bride used her hands to force it up into place, then had to instruct my wife how to slide down onto me (the newlyweds on their hands and knees trying to fit us together, and both of us playing dumb the whole time!). And when we got to 'doggy', my wife, on all fours with her butt in the air, feigned complete ignorance and asked the young groom to use his fingers to hold her pussy open while his bride steered me in. This was 'hands-on' training! "Oh, so that's how you do it!"
We'd fucked on beaches before, but now being under the close supervision of these young newlyweds added another dimension. For me, the hottest aspect of all this was that for the whole hour or so, with an raging hard-on I was on the verge of coming but held off by not stroking. Whenever we fuck for real, of course it's all over after one or two orgasms, but today we were 'learning new positions', not going for orgasms. That meant we had to hold out for an extended period, resulting in me erect and throbbing, and her open and wet the whole time. A prolonged sexual high! Frustrating but titillating.
Also, instead of an internet audience, we had a live one. I mentioned earlier that this late in the afternoon most of the other beachgoers had left—but not all! The four women who remained wandered around to our cove to see what was going on. While we were engaged in yet another innovative but unusual acrobatic configuration of our bodies that still somehow allowed my dick to be inside her pussy (I think the inside of her knee was somehow around my neck), they even asked us whether we were making a porn movie or training for an Olympic event! We explained the honeymoon pictures, and about how we decided to get private pictures of ourselves as well. The bride told them she just couldn't understand that this older couple (us) only knew intercourse a few boring ways, and therefore she had to teach us some new positions to make the photos more interesting. Well, at that, the four new women, once they realized we were going to continue fucking, or at least penetrating, described some of their own favorite configurations, so we got to try those, too.
By now the four women had figured out the deception we were putting over on the newlyweds, joined our ruse, and took active parts in further 'instructing' us.
We were the only ones 'fucking', although as I explained before, I don't really think positioning my dick inside her cunt long enough for the camera qualifies as fucking, since we weren't moving in and out, and no climax was sought. I think a better term would be 'coupling', like plugging in electrical cords, or hooking up railroad cars. Plug it in, click, Unplug; next position; Plug it in, click, Unplug. We had plenty of help assuming new poses, with lots of hands on us, moving one leg this way, turning my wife that way, or guiding my dick in when I couldn't see it.
