"Why'd we come out into the lake?" Dylan asked.
"I don't want to risk anyone hearing us," Adam replied.
"They're probably not up, but yeah. What's up?
"So, it's strange, right, all these girls hanging on us?"
"Totally. It's like they're all so horny, if it weren't for Dr. Catton around we'd be fucking all day."
"I know, right? They are all so hot to trot."
"No foreplay needed, they are wet, ready, and eager. You think something is up?"
"Yes," Adam nodded, deep in thought.
"I mean, if you got an idea, I'm all ears. Would love to bottle whatever it is and take it back to the states with me."
"Yeah. So, it could be the water, we filter it, but maybe it's drugged."
"What kind of drug would do that?"
"No idea. Imagine a derivative of MDMA, with a bit of inhibition lowering effects like alcohol."
"Certainly nothing I've heard of."
"Yeah, if I knew how to get some, I'd be a billionaire."
"If I knew how to get some I'd be fucking my way through sorority row at Lincoln."
"Yeah, so let's talk about that. I don't want to ruin a good thing, and I don't want to cross you. You got dibs on any of these hoes?"
"Nah. All good, not great. Ashley looks fine."
"Yeah. So here is what I propose. We keep it quiet. Dr. Catton can never find out. I've bagged Sarah and Lisa. You?"
"Macey and Anis. Sarah and Ashley blew me while we were out yesterday."
"Nice. Anyone catch you?"
"Not that I know. You?"
"Yes, kinda. I fucked Lisa with Macey watching, and neither batted an eye. Which got me thinking about this whole thing, how weird it is to be fucking some grad student while another one watches like it's no big deal. Something is up, man. These girls ain't party girls."
"They sure are acting like it. So how were they?"
"Meh. Lisa was a starfish, still was a screamer when she came. Sarah, now she's a freak."
"Always the quiet ones."
"Yeah man. Hot. Sarah has the tightest pussy I've ever used. Don't think she's had much action, but once I cracked her, she was wild. Kayla is just dying for some action. Ashley is another quiet one, but she's a total hottie, with curves for days. Samatha, tall and skinny and flat. She could be totally wild though. Heather is the hottest of them all, with those big tits and thick thighs."
"Yeah, totally. Macey's up," Dylan noted motioning with his chin.
"Noted. So, let's continue fucking in secret, I plan to get them all, as long as you're okay with that."
"Me too, bro."
"Make sure Dr. Catton never finds out."
"Agreed. You want to tag her?"
"Fuck no, not with these chicks available."
"Yeah, I'd need to be pretty desperate."
"You know, we should probably make a schedule. And that's another thing, these girls, watch over breakfast. See how Kayla and Samantha look this morning. Like they haven't slept, spending all night thinking of fucking, desperate for our attention. I tell you man, we gotta play it cool and manage them or things are going to get out of control fast."
"I'm with you. Fuck 'em when we are out in forest, or at night by the stream. The stream will help mask any noise they make."
"Great fucking idea. I'm not into bondage, but we need to come up with some gags to keep the noise down. Any ideas?"
Dylan thought for a moment. "Yeah, let me think of something."
"No drama, absolutely no hickies or bruises. Can't have Dr. Catton seeing anything."
"Agreed. You really think it's the water? Why hasn't it affected us?"
"Who's saying it hasn't? But I'm always a horndog, so it wouldn't change nothing for me. But I'm raw dogging these bitches, and I wouldn't do that back at home, so maybe?"
"I mean, me too. No condoms."
"But yeah, my current hypothesis is that there are plants or bacteria or something that are in the lake that are putting a drug in the water that is getting past our filers. Can't say if boiling takes care of it, but most of what we drink isn't boiled, just filtered."
"Interesting. Certainly these girls weren't acting like this on the way up here."
"Yeah. The first morning is when I started to notice. Something about this place bro. The spectrometer isn't set up yet, we'll have to run tests. Secretly."
"Fuck, Macey is the expert on that. You know how to use it?"
"No, but how hard can it be? Anyway, remember that shaman that held us up?"
"Yeah?"
"Well, first, it seemed like he kept on asking if we were 'married' to the girls. Second, there seems to be no evidence of large scale settlement here, just small shelters for two. Maybe this is the honeymoon spot for the local tribes? Come here, get horny, get freaky."
"Hilarious. Maybe. Hey, all these chicks are on birth control, right?"
"That is my understanding. There's a bunch in the med pack, enough for all of them."
"Camp's up."
"Yeah, we should go in. Keep your eyes and mind open. If we crack this mystery, it could make us both rich beyond our wildest dreams."
"You think the girls have figured it out?"
"I don't know. Keep your ears open, let me know if you hear anything. Sarah's a total brainiac, she didn't say anything. Who you aiming for today?"
"Samantha or Ashley."
"Cool."
The men bumped fists and waded back to the camp, where the women were waiting for them as if they were rock stars. Dylan and Adam glanced at each other with a grin and a shrug and greeted their adoring fans.
Adam pushed Heather and Kayla hard as they headed out on their mapping trip. He ignored their longing looks and focused on the task at hand. His plan was to get the work done as quickly as possible so that they could play later, and he was a strict taskmaster. The girls were completely compliant to his leadership, even seeming to compete on who was the harder worker. By lunch time, they had gridded out two thirds of their goal for the day. The work wasn't arduous, but still everyone was sweaty. As he had planned, they broke for lunch near the waterfall.
"Hey, why don't we take a quick shower in the waterfall," he suggested.
"Oh my God, what if someone sees?"
"Oh, I'll definitely be watching," he grinned as he peeled off his shirt.
He watched the girl's reactions closely. Their jaws dropped and their eyes glazed over. This was going to be a big step, but if his reading of the situation was correct, they would agree. Heather looked at Kayla and then back to him. With a shrug and a giggle, she pulled off her tee. Kayla followed suit, and then turned her back and peeled off her sports bra. With a lascivious look over her shoulder to Adam, she squealed, pulled off her shorts, and pranced into the waterfall. Heather looked stunned for a moment, then finished stripping and joined her.
Heather and Kayla laughed and shrieked as they stood under the curtain of water. The sight of them, their naked bodies slick with rivulets of trickling water, filled Adam with an almost overwhelming urge to run in and ravish them both. Instead, he took a deep breath. His plan worked.
Let's take it slow.
The sun glinted off the rough face of the stone outcropping that formed the edge of the pool and cast a shimmering veil over Heather's full breasts. He felt himself grow hard as he watched her hands travel down her body in a gentle caress.
"Come on in," Kayla shouted over the roar of the falls. She beckoned to him with one hand, while the other sensually caressed her own pert chest.
Adam didn't need to be asked twice. He quickly stripped to join in their fun beneath the cascading waterfall. His skin prickled from the force of its spray and his heart raced at being able to enjoy the two women. The three of them splashed around in the waterfall and each took turns to stand beneath the cascading water. As they stood there in all their naked glory, Kayla closed her eyes and spread her arms out wide, enjoying the feel of the refreshing pressure on her skin.
