In upstate New York, a favorite fun activity is to float on a tube on the Esopus river, and in the summer it's often clogged with hundreds of floaters. Not as well known is upstream from the focus of tubing are several tributary steams feeding the river, many quite beautiful and also secluded. One of my favorites runs thru the woods and has several rock-bordered pools the water runs thru forming perfect spots for groups to swim or lay in the sun - often nude.

One sunny summer day myself and a group of 5 friends crammed in a car and equipped with snack and beverage coolers laid claim to one of the larger pools. As we set up several other groups trickled in around us, and everyone was stripping to the buff in the warm sun.

My group was well aware of my horse-hung status, and in fact I'd been inside two of the women and one of the men, so my flacid kielbasa earned no comment from them as I stripped, but after standing up naked I heard "Holy fuck look at that guy!". It was a group of 4 setting up close by, three women and a guy and it was the guy who spotted and commented. I just smiled and waved and the guy and one women came over to the pool edge and introduced themselves and started peppering me with questions.

Do you get dizzy when hard? No

Does it get you laid? You bet

Do you have problems with clothes? Only skinny fit

And my favorite for an opening line:

Does it get bigger when hard? There's only one way to find out.

By this time the attention was starting to arouse me and my cock was partially engorging and now sticking out at a 45 degree downward angle. The woman stepped over and sat on the rock in front of me and started giving me a bj. With that stimulation it only took a couple minutes before I was fully engorged and hard, to the exclaims of the other folks. She couldn't get me in her mouth so she stood and we started kissing and her stroking my shaft with her left hand. I could feel her erect nipples pressed against my chest while I was gripping her ass. I pushed her down sitting, trapped my throbbing cock between my body and hers, rubbing against her, both of us breathing hard. I stopped and went and got a towel and Cetaphil lotion for lube, put the towel on the rock next to her and hoisted her on it for comfort, then bent her over kissing her. She then said in my ear "My last boyfriend wasn't as big as you but he was still hung so I know what to do, so get inside me!"

Music to my ears.

I squirted lotion on my dick, and started to penetrate her. At first I couldn't, then felt her relax and I popped in. I slowly pushed in, her gasping, until I felt my cock hit bottom, then moved around and slid past her cervix into her fornix until I couldn't go further, then just stopped and soaked. She was gasping and moaning, gripping my ass tight, and I was moaning too, neither of us moving.

It was the whole atmosphere - the babbling water, warm sun, cool breeze, aroused onlookers - that made this feel better than I ever had. Her vagina was snug, smooth with slight ripples and I filled and stretched her completely and still had a couple inches of dick left. It felt better on my cock than any vagina I could remember. We were almost in another world of orgasmic pleasure, completely oblivious to anything except us.

She wispered in my ear "I think you should finish, it's starting to get uncomfortable" so I started with long deep slow thrusts rapidly speeding up with us both loudly vocal. She suddenly shouted "I'm cuming'" and her whole body shook and I could feel her throb. I went "Can I cum in you?" And she said "Nut yourself dry big boy!" and that's when I remembered I didn't use a condom. I think she sensed hesitation and said "I'm on the pill." No further invitation, with a shout I popped and started pumping, some of the strongest I ever had. We both slid off the rocks and collapsed in the water, my pulling out in the water which was a cool shock to my still-rigid shaft after her warm insides, cooling off and kissing, then I opened a couple beers we enjoyed in a post-coital glow.

We were there for a while and traded phone numbers. I hooked up with her several times after, and when she found I was bi, she hooked me up with the guy who was there that day, also bi. Nothing we did, though, came close to the orgasmic glory of that day on the stream in the sun.
