We reached a point where the creek forked off in several directions. We clung to the left wall of the canyon and followed the water around the bend to where we could hear another small waterfall. Up ahead, Becca had stopped and was peering over a small bush, toward the waterfall. I came up behind her. It was then that I realized why she had stopped. Under the small waterfall, I saw a man’s back, with two legs sticking out by each hip. I looked closer. It was Jim, our muscle-bound New Zealander guide and the legs belonged to Jen. He was standing in the creek. She was seated on a rock just behind the small waterfall. By the way his hips were moving, it was clear that they were fucking. He had his arms around her hips, supporting her on the rock as he thrust into her.
I grabbed Becca by the hips and motioned for her to move forward. We got closer, so we could get a better view, though we were still 15 to 20 feet away from them, with a large rock to provide us some cover. From my new vantage point, I could see Jen’s face and breasts. Her eyes were closed, lost in passion. It was the most erotic sight I’d ever seen, and despite all the sex I’d had over the last few days, I was instantly hard. And I could tell Becca was just as transfixed by what she was seeing.
We were standing in a portion of the creek with very warm water that came up to our mid thighs. Becca was directly in front of me, wearing nothing but a skimpy bikini bottom. Reflexively, I reached out and grabbed her hips, rubbing my erection against her ass. She sighed, offering no resistance. As we continued to watch, I lowered my trunks and began rubbing my bare cock up and down the crack of her ass. She pushed her ass up against me and sighed again, continuing to watch Jim and Jen. I reached down and moved her bikini to the side, exposing her pussy, and a second later I was inside her.
For what seemed like a long time, I slowly thrust in and out of her, both of us continuing to watch the scene in front of us, silently. At one point, Jim lifted Jen off the rock and into the creek. He spun her around. She put both hands on the rock and extended her ass toward him. In an instant, he was back inside her, fucking her aggressively from behind, his huge arms wrapped around her, groping her.
By this point, Becca had begun fingering herself and I could tell she was getting close to orgasm. As much as I’d enjoyed the show, I’d seen enough by that point and I wanted to focus on Becca. I pulled out of her and spun her around. Then I reached down, lifted her up and gently laid her down on the sandy bank of the creek. She spread her legs, welcoming me, and I wasted no time plunging my cock back inside her. I dug my hands into the wet sand below her thighs, propping her legs up high and wide, maximizing my penetration. We kissed passionately as my balls slapped against her over and over.
After a few minutes of this, we were both nearing orgasm. It was then that Becca’s eyes suddenly went wide. “Clint! Clint! Stop!” she whispered urgently, putting her hands on my chest to stop me. “They’re watching us.”
I stopped thrusting and looked back over my shoulder. Jim and Jen were standing in the creek, about 15 feet behind us. They were no longer screwing but were just standing there, casually watching us, smiles on their faces. My brain was telling me I should stop. But I was so close to coming, so desperate to get my release. So instead I turned back toward Becca, looked her right in the eyes, and began thrusting again, urgently.
Becca looked shocked, but after a few seconds, I could tell that her lust had regained control. Her fingers shot back down to her clit and she began fingering herself frantically. Her eyes soon grew wide again and she started saying “oh god… oh god… oh my god… oh fuck, I’m coming, Clint!” Her eyes closed and she threw her head back into the sand as she climaxed, her hips shaking and her pussy spasming, pushing me over the edge as well. I’m not sure quite what came over me, but instead of coming inside her, I pulled out at the last moment and watched as my cum shot across her belly and up onto her chest and face. Feeling the droplets hit her face she opened her eyes again and lifted her head. She smiled and shook her head, as if chiding me for acting like a porn star. But she was all smiles, basking in a post-orgasmic glow.
By the time we stood up to wash ourselves off in the creek, Jim and Jen were gone.
Chapter Three: Putting the Cots Together
That night, during dinner, Becca ditched me to join Lisa and Alesha. With some amount of trepidation, I went and sat next to Alan and Brent, who were sitting by the bank, drinking beers. As we spoke, it quickly became clear that Alesha had already filled Alan in on our “swap” and the circumstances that led to it. Alan was a doctor and former army field medic and he had a very direct way of speaking; he was never one to beat around the bush. Within seconds of me sitting down, he was peppering both Brent and I with questions. He asked us how we felt about what had happened, how we thought Becca and Lisa were handling it, etc. It was awkward to talk about, particularly in front of Brent, but in a way, I was hugely thankful to Alan for making us get it all out in the open. It was like a group therapy session. And by the end of it, Brent and I were in a much better place, once again friendly and relatively at ease with each other.
Eventually, the conversation turned from “the swap” to a more general discussion of the sexually charged atmosphere of the last few days: the loud, ubiquitous sex at night, the increasingly frequent nudity on display each day. Though I’m almost never one to kiss and tell, I found myself telling Alan and Brent about our experience at Havasu earlier, stumbling upon Jim and Jen and then having sex in the creek. As it turned out, both Brent and Alan had similar stories to tell. Alan told us that he and Alesha had snuck off and had sex at the creek as well. And Lisa had given Brent a blowjob after they’d watched Candy and Keith going at it.
At one point, I commented that I hadn’t had this much sex since I was in my 20s and expressed some doubt that I could keep up this pace for two more days. Brent nodded in agreement. It was then that Alan excused himself briefly, heading back toward his cot. When he returned, a minute later, he reached into his pocket and took out a handful of what looked like individual packs of aspirin or ibuprofen. He gave several to both Brent and me. It took a moment for me to realize what they were: Viagra single packs. “This should do the trick,” Alan said. “It’s one of the perks of being a doctor. I don’t use these much, but they’re kinda fun once in a while. I’m planning on taking one tonight.”
I’d never taken Viagra or Cialis or anything like that before, but I had always been intrigued. The night had suddenly gotten more interesting.
It got even more interesting after dinner, when Becca told me that she and Lisa and Alesha had, after some discussion, agreed to rearrange our cots, moving all six of them into the same little clearing that originally just held ours. Intrigued, I walked through our sleeping area on the way back from a bathroom break. The cots were all packed into a sandy area about 15 feet in diameter. While each couple’s cots were spaced out on the perimeter of the circle, they were all close enough to each other that, with any amount of starlight, it would be easy to see what the other couples were doing. And no doubt that was intentional.
Once I’d made my way back to the communal area, I sat down next to Becca. She looked at me immediately, clearly wondering what I thought of the sleeping situation. I raised my eyebrows and then whispered into her ear, “not much privacy there. Are you sure you’re okay with this?”
“Not really,” she whispered back. “I can’t stop thinking about what we did earlier, and how they were watching us. Is it weird that I kind of got off on that?”
