The trail leading down to the river is steep and winding but has steps carved into the hard clay and rock. It ends on a very large flat topped boulder about ten feet above the water. I had led the way down and had paused at the edge of the brush line just above the boulder to look around before we came out into the open. We were all three naked except for towels over our shoulders.
The river is well over a hundred yards wide here and has a slow lazy looking current. Mary looked down over the edge and commented, "The water sure is clear, I can see the bottom."
I chuckled and replied, "I should hope so, it's only about knee deep on this side. The main channel is on the other side. If we want to swim instead of wade, we need to follow the bank down stream a little ways to where a creek feeds in. There's a pool about six to ten feet deep at its mouth. You both can swim, right?"
Rita grinned and nodded, "I swim like a fish and Mary can dog paddle enough to keep her head above water."
I looked at Mary for a moment and then said, "Well, I guess that'll have to do but you be careful and stay away from the current. It's not very strong but if you don't swim well it could carry you a ways down stream before you could get out of it. We're not exactly dressed for cross country hikes."
"Yes, sir." She replied and then added, "I swim good enough underwater to stay out of trouble, I just have a problem with the floating part. I sink like a rock."
"Yeah, it's all that lead in her ass," Rita chipped in and then laughed as she smacked her girlfriend solidly on the ass.
"Hey, at least I've got an ass," Mary shot back and danced around, trying to return the slap.
Rita moved away laughing and said, "I can't help it if I got the tits and you got the ass."
"Yeah, between you, you'd make a pretty decent woman, if you mixed the parts right," I said with a grin. That got me a slap on the ass from Mary as they ganged up on me, protesting all the way.
With a laugh, I danced away, and headed off down another trail along the river back. "Okay, okay, I take it back. You're both beautiful in your own ways. Come on, let's go get wet."
This trail was flatter than the first and screened from the river by small trees and bushes. At the end of it, there was a steep section down to a small sand beach at the mouth of the creek. Large willow trees and oaks overhung the water on three sides but there was a large open section out toward the river. A rope swing hung from a large willow limb above the deepest part of the wide pool.
I went on down the steep incline but the girls paused to look around. I hung up my towel on a tree limb and waded into the cool water of the pool. Two steps and it was above my waist. A sound from up river caught my attention and I grinned as I recognized it as an outboard motor. This should be fun, I thought as I turned to watch the girls.
They were talking quietly and didn't seem to hear the motor or at least it wasn't registering. I waited, as the sound got louder and louder. Finally, I called to them, "Are you two paying attention? That sound you hear is an outboard motor and it's probably attached to a boat loaded with at least a couple of fishermen. Now, you might not realize it, but you're both stark ass naked and you'll probably cause those poor guys to have an accident, if you continue to stand where you are."
Both girls just looked at me for a second and then Rita said, "Oh shit, what should we do?"
I laughed and answered, "Either hide in the bushes or get down here in the water. I'd just decide and do it quickly if I was you, they'll go by here any minute now."
Mary started down the hill and Rita started back up the trail. Then they both reversed directions and nearly ran into each other; it was a Chinese fire drill for a few seconds before they both headed up the trail and squatted down behind some bushes. I was laughing my ass off and they were staring daggers at me. I had a feeling that I would end up paying for the laughter but what the hell, I had to have a little fun, didn't I.
As the boat passed, I waved at the man and woman in it, and they waved back. As they motored around the bend below the creek, I turned to the girls and grinned. "Okay, you can come on down, if you want to. I think it's safe now."
Mary stood up first and said, "You're an asshole, you know that?"
"Yeah!" Rita added as she stood up. "You could have warned us earlier."
I chuckled and replied, "Just think of it as a lesson in paying attention to your surroundings when you're out and about naked. You have to look and listen, or you'll end up flashing people that you might not want to. The guy in the boat probably wouldn't have minded a bit, but his wife wouldn't have appreciated it in the least."
They had walked down the hill as I talked and were hanging their towels next to mine. Mary turned to Rita and said, "He thinks he's so smart."
Rita giggled and replied, "Well, in a lot of ways he is, or at least he has all that experience to draw on. We'll get there ourselves one day, if we live long enough."
"Yeah, I hear you but it still gripes me. He could have warned us earlier," Mary shot back.
"If I had, then I wouldn't have had the fun of watching you two, running around like a pair of chickens with their heads cut off," I said with a laugh.
They looked at each other for a second and then both of them were on top of me, trying to drown me. I was laughing so hard that they nearly succeeded.
I finally grabbed Rita around the hips, tossed her out into deep water, and picked Mary up around the waist, with her back to me. I held her up out of the water and asked, "Are you ready to join Rita?"
She wiggled in my arms and shook her head.
"Ok, then," I said and started to lower her to her feet. As I did, my rampant manhood slipped between her thighs and ended up pressed tightly against her hot sex.
She clamped her legs together and wiggled slowly back and forth along its length; little sounds of pleasure coming from deep in her chest. Rita swam up to stand in front of us, a frowning, questioning look on her face.
"Hey, what are you two up to?" She asked suddenly.
