“Your boyfriend, Gunnar?” I asked.

“Pfft, yeah, he is probably with your sister. Those two have been going at it non-stop for the past couple of days,” she exclaimed with a laugh.

“You know about that?” I questioned.

“Of course, I do! He’s my boyfriend,” she replied.

It was more than I could even begin to process. I mumbled something about letting him know as I mindlessly left the room.

As I walked back to the cabin, I didn’t even know how to go forward. I was greeted by the familiar sounds of Chan and Gunnar fucking inside of the cabin. The lights were off, but there was enough moonlight shining into the cabin that allowed me to see an outline of their bodies.

Gunnar was sitting on the edge of the bed, while Chandra faced him and straddled his body. He would unleash a flurry of strokes as the crisp sounds of impact echoed through the night air, and then he would abruptly stop. His tongue caressed from her breasts to her chin in long strokes, seemingly marking her as his property. Once again, he had Chandra begging him to finish her off. His arms locked around her chest, holding her in place as he restarted with slow, powerful strokes. He grabbed onto her hair and yanked her head backward slightly.

I could hear him say, “Yeah, cum on my cock again! You know how much I love that.”

From the manner he spoke those words, I was convinced that he was inferring that he had made her cum only a few minutes prior. He pinned her against him tightly as he continued to slowly grind the entire length of his cock inside her. Chan was shaking and letting out squeaking noises as she struggled in his grasp.

Once she was through, it was once again Gunnar’s turn. He started to slam away at Chandra with reckless abandon. A slower, deeper “clapping” sound rang out from the cabin as I watched him rail my sister like she was a twenty-dollar whore.

I couldn’t take it anymore. Just as Gunnar had grunted out his release, I burst into the cabin and turned on the lights.

“Your girlfriend wanted me to tell you that she wants you back at the apartment. That’s what she said after I fucked her.” I snarled.

I turned the lights off and closed the door. I didn’t even go back to the cabin that night, in part because I probably hurt Chan more than anyone else (other than myself, of course.)

As I wandered around, I noticed the lights were on at one of the other private cabins. When I walked by, I saw a man and a woman casually fooling around on top of one of the beds. They looked to be in their forties, and the lady, in particular, seemed like she had really fixed herself up for the occasion.

Her face had a considerable amount of cosmetics applied and she clearly had recently shaven all over her body. They each had a bit of a mom and dad-bod thing going on but of the two of them, she was probably in marginally better shape. She had shoulder-length, light brown hair, and reasonably large breasts. They had a bit of sag to them, as you would expect for a woman of her age with natural breasts, but overall they still looked pretty good. The man had a fairly handsome face but he had a decent-sized belly and didn’t seem to be in very good shape. He had uneven, dark body hair all over and his cock was pretty average at under six inches long.

I watched them kiss and touch one another for a while. Then I heard footsteps coming. I quickly walked away, pretending not to have been spying on them. Once I was out of sight, I found a place to watch the action in the cabin without being seen.

It was another couple. They seemed to be a bit younger than the ones in the cottage and in significantly better shape.

The lady was quite attractive. She had long, blonde hair, and was just slightly underweight. Her small breasts had started to sag in a way that they seemed to lie almost flat against her chest. She was mostly smooth-shaven, other than a short, thin strip of dark pubic hair that was neatly trimmed into a small heart-shaped pattern. She had long, skinny legs and an overall nice, petite body.

The man walking with her was in relatively good shape as well. He wasn’t chiseled, by any means, but he looked like was still pretty active. He seemed like the sort of guy that women would find handsome, especially with his prominent, dimpled chin. Other than his legs, arms, and a small patch of hair on his chest, his body was mostly shaven as well, including his cock. Since his dick was soft, it was hard to tell, but he seemed to be slightly above average.

To my surprise, they knocked on the cabin door and the first couple invited them in. They talked very briefly. Then the first man joined the blonde on one bed, while the younger man sat with the older woman. I watched as they gradually started to fool around, much like the first couple had done before. It was pretty boring and there wasn’t much action, but I didn’t have anything better to watch, so I stuck around.

Slowly, individuals and couples started to gather around the cabin. They scattered around to different sides of the building. I was quickly beginning to wonder if the abundance of large windows on the cabins, coupled with the absence of window coverings was intentional.

The onlookers were certainly not trying to camouflage their presence either physically or audibly. A brief discussion occurred inside the cabin, and then the action started to pick up. Unfortunately, I was too far away to actually see it in any degree of detail.

The couples started out with assorted exchanges of oral sex. I could see the individuals outside of the cabin touching either themselves or their partners, if applicable. I decided that it was alright to make my presence known and get a better look, particularly of the blonde girl. I slowly crept forward, remaining ten feet or so behind the nearest voyeur.

As the action started picking up, I could see why the two couples might have decided to hook up. The older woman got a handsome younger man with a slender, but reasonably lengthy, rock-hard cock to serve her needs. He also paid considerable attention to her breasts, which were much larger than those of his partner.

The young woman got a very attentive partner with a thicker, but shorter, cock. He was clearly enamored with her looks and body and seemed willing to do anything she wished.

Over on the other side of the cabin, the younger guy took control with his new partner. He was trying out one random position after another, switching it up every several minutes.

The young woman, conversely, had taken charge on the other bed. She had her new partner flat on the bed and was slowly and deliberately riding his cock. I couldn’t help but notice that she spent a considerable amount of time with her hands over her breasts. She didn’t seem to be doing it for pleasure, but, instead, to conceal them.

It made me feel bad for noticing what seemed to be her only physical flaw. I know that I am far from perfect, so seeing that she was clearly self-conscious of them made me feel bad. It was obvious that any guy would have been lucky to have been with her, and I was pretty sure that she was easily the most watched of the group inside that cabin.

There was a definite imbalance in the level of aggressiveness on the two beds. Even when the older man took control of the blonde girl, he was the far more controlled and measured of the two men. Meanwhile, the younger guy was thumping away as he squeezed, licked, and sometimes nibbled at the older woman’s breasts.

Not surprisingly, the younger man would be the first to finish (if you don’t count the observers.) Many of the couples were fucking, while the solo men would approach the cabin one by one and blow their wad onto the wood siding. I thought to myself that I obviously knew what I was doing the other day.

The “first to finish” couple joined the others and the younger man presented his cock for the blonde to lick clean, while the older lady cheered on her partner. The blonde seemed like she was on the verge of orgasm with the gentleman looking like he wasn’t far behind. He managed to just get her there with the help of his thumb before he pulled out and sprayed thick globs of cum onto her tummy. The crowd outside cheered his efforts.

His original partner sucked him clean and he licked her “recently creamed” pie clean in return. The show seemed to be winding down and the crowd slowly dispersed, so I followed suit. I couldn’t help but think that this all seemed to be pretty routine for the people involved. Nobody seemed to be the least bit surprised that any part of this was happening.

Eventually, I ended up sleeping on a hammock that night. The next morning, I had a change of heart, though, and decided to act like everything was normal.

I bumped into Skye at breakfast. Gunnar and Chandra were together at a different table. I really do hate him. Just as I suspected, everything was back to normal, whatever that was. It had become apparent that I was the only one of us who wasn't clued into what everyone's personal situation was.

I told Skye the story about the scene that I saw the prior night, well…actually earlier that morning. She didn’t seem surprised and she asked me if I went for a romp with the blonde girl, afterward.

When I told her that I hadn’t, she seemed surprised. I told her that couldn’t believe some of the kinky stuff that goes on at night. To that she replied, “What do you expect? A lot of the people here are swingers, too.”

I nodded my head, but I didn’t know what that meant. Fishing a bit, I followed, “Yeah? So they do some crazy stuff then?”

“You don’t know what a swinger is, do you?”

“Um, no,” I admitted.

She gave a quick explanation, which triggered something in my head. I had to ask her if Gunnar and her were swingers, as well. Skye responded that she didn’t really consider themselves as such because they had never interacted with another couple before. She classified themselves as having more of an open relationship. Then she added being a swinger didn’t exclusively mean that two couples had to be involved anymore. There were plenty of single people who came to the resort to meet both couples and other singles. In this case, it just seemed to be a generic term that was used to describe people who enjoyed casual, impromptu sex with strangers.

Skye said that she had an hour before she had to be at her next event, and asked me if I wanted to join her back in her room. That seemed like an offer that couldn’t be refused, so we quickly finished our breakfast and headed that way.

Once inside, Skye sat at the edge of her bed with her legs spread wide apart. “Now, I’m going to teach you how to eat pussy,” she announced with zeal.

I was more than willing to learn and couldn’t think of a better person to learn how to do it with than Skye. She gave me very detailed instructions on where to put my tongue and how to move it. I was directed to be gentle at first, then to press more firmly the more aroused that she got. She even showed me exactly where her clit was, but I didn’t really see anything. At least I knew where to find it. But before she let me get started, Skye had one more surprise for me.

“So, I’ll make you a deal. If you can make me cum, I’ll let you fuck me any way you want to. If you don’t, then it’s blue balls for you.”

To be honest, there was no downside to the arrangement for me. I got to be taught a sex skill, and I got to taste Skye’s beautiful pussy for the first time. If I was fortunate enough to make her cum, the deal would be all the better.

I leaned in slowly and took my first tentative lick. I gave every bit of her soft, delicate vulva a taste before redirecting my attention to my intended target. Skye continued to coach me and guide me when I drifted off-target. She was also not hesitant to let me know when I was doing something right. When she finally let out that first sigh, I felt like I was actually catching on.

The familiar click of Skye’s phone made me wonder if she was going to document all of our sexual exploits. It wasn’t a problem for me, but I hoped she intended to send me the images at some point.

She grabbed me by the hair and pulled my head away. “Now look at it,” she ordered.

I wasn’t sure what she was referring to, but she delicately peeled back her hood and showed me how much her clitoris had grown. I could see it and suddenly I had a larger target. I remembered that Skye said I should be more aggressive as we went on, so I did just that.

After our first sexual encounter, I was eager to redeem myself. I realized that she was holding my hand through this little exercise, but I knew if I wanted any hope of stealing her away from Gunnar, I had to be able to satisfy her in every way that he could.

I leaned forward, once more. I was still deliberate in my actions but pressed downward with a bit more force. Much more quickly than the first time, Skye started to respond to me. She gripped her knees with her hands and spread her legs even wider than before. Feeling bold, I wrapped my arms around her, squeezing her firm backside. I used my newfound leverage to better control how much pressure I was implementing.

“Oh, fuck! I’m gonna cum. Don’t stop! Don’t fucking stop!” she cried.

My tongue was getting very fatigued and I was clearly slowing down. I hoped that more subtle movements with increased pressure would get Skye over the finish line.

I could feel her body start to tremble, and she let out several jagged gasping sounds. There was no doubt in my mind that I could make it, at that point. Skye’s body curled up as she buckled over top of me, almost knocking me off-target. She was squeezing me tightly, as she humped my face. She cried out to me in a squeaky voice that cut in and out. Then, she released me and fell backward onto the bed.

As I slowly climbed to my feet, most of my face was wet with my own saliva. I was smiling so hard that my cheeks hurt. Skye rolled around on the bed briefly, clenching her hands between her thighs and reveling in the moment.

“Alright,” she sighed, “I guess you get to have your way with me now.”

Just hearing her say those words gave me goosebumps. Skye rolled over onto her hands and knees, stuck her ass up in the air, and lowered her head.

“Let me guess, face down, ass up?” she asked playfully.

“No…um…I just want to look at you. Maybe something face-to-face. Isn’t that the way that most couples do it?”

“Missionary, huh?” Skye giggled. “It’s not the most adventurous, but it gets the job done.”

Skye rolled onto her back, spread her legs for me, and smiled. When I approached her, she quipped, “Aren’t you forgetting something?”

It took me a moment, but I finally realized what she had meant. I walked to the nightstand and retrieved a condom. I fumbled with it a bit, before finally getting it in place.

Once I had climbed onto the bed, I started to feel quite nervous. My hands got shaky as I had to position Skye’s body appropriately. As I edged closer, I nervously held my cock as I got ready to penetrate her. I looked at Skye for encouragement and she responded, “Do what you want to do.”

My shaky right hand guided my cock inside of Skye. Her pussy was so warm and wet as it snugly wrapped around my cock. I lowered my torso so that I hovered just above her. It took a moment to get situated so that I was comfortable and had some degree of leverage. I locked eyes with Skye and she gave me permission to take charge.

I started slowly as I gently ran my fingers through her hair. She never ceased to amaze me with how stunning a woman she was. As I picked up the pace, her breasts started to bounce with each of my thrusts. They glanced off my chest with each repetition, which I thoroughly enjoyed.

While I knew that I wasn’t going to last long, I wanted to make the most of our second encounter. I pulled back slightly and hooked my arms underneath her thighs. As I folded her knees back into her chest, I leaned in, once again, and gave her what was supposed to be a look of confidence. She smiled at me, looking a bit surprised that I had turned up the intensity.

I fired back up, this time quicker and harder than before. I pumped away until my body wouldn’t respond anymore and my cock was throbbing inside her. I stared at Skye once again, hoping that she would give me the signal to finally kiss her, but I didn’t receive it. I backed away slowly, feeling a bit better about my performance than last time.

When Skye got up, she checked her phone. It was time for her...
