“Are you sure you know where you’re going?” asked Jen as Kevin turned off the highway onto an old dirt road.
“Quite sure,” he replied. Kevin is my older brother. He met Jen at school and they’d been seeing each other for a few months now. Summer vacation had just started and he said he knew of a nice place to go swim for the day to beat the heat. It sounded like a good idea at the time, but as we go further down this road, the woods aren’t the only thing that’s looking shady.
I look over at Cathy, sitting next to me in the back seat. Cathy is Jen’s younger sister; she’s the reason I’m along on this trip. She convinced Jen that it would be better to bring her along than leave her alone all day at home. I was brought along to keep her company.
My name is Mark. I’m the same age as Jen. Due to the oddities of the school districts, we went to different schools even though we live down the street from each other. It’s another oddity why Kevin and Jen didn’t bother to introduce us earlier.
She is looking around at the deep woods and the decrepit roadway. Then she notices me watching her and gives me a nice smile. I grin back. I’m never sure how to act around girls anymore. Last year, I could just ignore them. Now, I find the shape of their bodies and movements fascinating while at the same time being scared to death of interacting with them. Maybe that’s why Kevin never mentioned Cathy to me before.
“We’re here,” Kevin says as he drives his Jeep into an open clearing.
“Oh, wow! This is beautiful,” gasps Cathy as she looks around. The old dirt road we had been following opened up into a grass-covered clearing. Off that clearing is a still lake with a tall waterfall crashing into it on the far side.
“This used to be an old campground a dozen years ago, but it closed down and was forgotten,” Kevin explained. “It’s a nice quiet place, and the water is cool and good for swimming. A friend told me about it during graduation.”
As we all got out, Jen walked over towards Kevin and wrapped her arms around his neck. “Well, this is beautiful,” she said and gave Kevin a deep kiss.
I glanced awkwardly around and went to the back of the Jeep to pick up the basket and towels. Cathy turned towards the water on the other side of the clearing. She peeled off her shirt and shorts, revealing a yellow bikini. The color complemented her sandy-brown hair and her light skin nicely. I also noticed that she was curvier than I first thought. She looked back at me and shouted, “Race you to the water,” and took off towards the shore.
Kevin and Jen immediately striped down to their swimsuits and took off after Cathy. I was stuck holding the blankets watching them run off. I tossed the blankets in a pile in the middle of the clearing, peeled off my shirt, and ran after them. By the time I got to the edge of the water, Cathy was half-way across the lake, while the other pair was splashing water at each other in the shallows.
I swam out towards Cathy but when I got near the middle of the lake and lifted my head up, she was nowhere to be seen. Suddenly, I hear a “Got you!” from behind me as Cathy jumped on my back from behind, pushing me down under the water.
I tried to turn around and get back to the surface. I could see Cathy ahead of me and surfaced right next to her, drenching her with a splash. After the initial expression of shock crossed her face, we both started laughing. I particularly liked the way her chest bounced when she laughed.
We swam around the lake together, enjoying the cool water. The waterfall on the other side of the lake was really nice. It was so tall that the flow of water when reached the bottom was scattered enough that it was like being in a light rain shower. Under that shower, when we were swimming close together, she darted in and gave me a quick smooch, before swimming away out of reach.
“Want to head to shore for a snack,” I offered, hoping to make some use of that basket of treats I’d been forced to carry.
“Sure,” Cathy said.
We reached the shore and the pile of towels that I dumped. As I toweled off, I realized that we hadn’t seen Kevin or Jen in a while. As I looked around, I saw Cathy over by the edge of the clearing, near some bushes. She was waving in my direction, and as I started towards her, she indicated to be quiet.
“What’s up,” I asked quietly when I got over to her. Cathy pointed towards a gap in the bushes and I looked through.
Behind the bushes in a small clearing, I could see Kevin and Jen. Jen was lying flat on her back. Her bikini top was untied and lying to either side of her generous breasts. Kevin was kneeling over her, holding both breasts with his hands, kneading them slowly. As we watched, he bent down and started licking one of her tits. Jen’s head was slowly rolling back and forth and you could hear little sighing sounds coming from her.
Both of us were watching with rapt attention and breathing faster. “Are they supposed to be doing that?” I asked.
“I wonder what that would feel like,” Cathy mumbled.
Her comment broke my reverie. “What?”
“Why don’t you try it? I know how you’ve been looking at my tits.”
Well, why not? I reached out towards her breasts, taking one in each hand. I could feel their weight and firmness, even through the damp bikini top. There was also a hard point right in the middle. Cathy gasped sharply when my thumb ran over that bump. I jerked my hands away at the noise. “Are you okay?”
“Fine… it was just intense,” she nodded. “Keep doing it.”
I put my hands back over her tits, giving them little squeezes. After a moment, Cathy reached back and untied the string holding the top on. The material fell away in my hands and then onto the ground. My hands were now directly on her tits and it felt much smoother and warmer. I could see the little pink circles in the middle with the tiny nipple points sticking up. It’s odd how the nipples could be so hard when the rest of the breast was so soft.
I leaned down towards one of the nipples, watching for any signs of disapproval from Cathy, and put my mouth around her left nipple. She gave another gasp as my tongue touched her skin, and sucked on the nipple point.
Cathy wasn’t sitting idle during this either. I felt her hands move down my body towards my swim trunks. When her hand glanced against the bulge of my cock, I instinctively jumped back.
Cathy motioned back towards the bushes and I looked over. Kevin was kneeling straight up now, with Jen sitting up in front of her. She had pulled his trunks down to his feet and was moving her hands all over his cock which was sticking straight out in front of him.
I was sitting on the ground now and Cathy crawls over towards me and says, “Let me see too. Is yours that large too?” She reached out towards me, her tits hanging in front of my face, mesmerizing me, and grabbed the waistband of my trunks, pulling them off me.
My cock sprang out in front of me. Maybe it wasn’t quite as large as Kevin’s (just like Cathy’s tits weren’t quite as large as Jen’s), but this close, it seemed to make quite the impression on Cathy. She seemed as uncertain about what to do with it as I had about her tits. Cathy reached one of her hands out and touched the tip, flinching back when this caused my cock to twitch involuntarily.
Cathy looked back at what Jen was doing and then reached out her hand and put it around. “It’s so soft,” she said, “but so hard at the same time.” Her hand started slowly moving up and down the outside. I was leaning back, just taking in the feel of this. It felt way better than when I touched it myself.
I could feel myself getting close to cumming though, and I didn’t want to freak Cathy out. Instead, I sat forward and ask, “Can I see yours too?”
Cathy clearly looked reluctant and I could see her mulling things over in her mind. She still had a hold of my cock though, slowly pumping it. Then she came to a decision, smiled at me, pushed the bottom down her legs and sat down on the towel that we were drying ourselves with earlier.
I leaned forward and looked down between her legs. I hadn’t seen a pussy before and I didn’t really know what to expect. There was thin brown hair around the opening. I tentatively reached out and touched the slit and found it very hot and very slick. As I stroked up and down, Cathy’s hips squirmed around.
As my finger reached the top of the slit, I felt a little bump. When I touched it, I heard a loud gasp from Cathy. “Right there…” she said. “Not too hard.” As I rubbed my finger around in circles, I could feel even more wetness leaking from her, making my finger very slick. “Not too hard,” she said.
I looked up from her pussy up the rest of her body. Cathy was breathing quite rapidly. Her tits were heaving up and down on her chest, and she was rolling her head slowly back and forth, the same way Jen was earlier. That reminded me of our siblings, so I glanced back over across the bushes.
“Cathy, sit up and look at this,” I said. We could see Kevin was on top of Jen now, both lying flat on the ground. Kevin’s ass was bobbing up and down, causing Jen to slide a little bit back and forth.
“Are they…” Cathy asked.
“I think so. They certainly look like they’re enjoying it.” My finger, which was still at Cathy’s pussy, stroked up and down a few more times, as I asked, “Do you want to try it too?”
Cathy paused and slowly said, “Do you think we should?”
“Not any more than Jen should,” I replied. Actually, I was pretty sure we shouldn’t, but I didn’t want to stop now.
Cathy appeared to be pondering. “Will it fit?” she asked, as she put her hand back on my cock.
“Let’s find out,” I said, as I laid her back on the towel. I lay down on top of her. The tip of my cock brushed against her pussy, causing both of us to gasp at the contact. I rubbed the tip up and down the opening and then pushed in.
It was a very tight fit. Even though I felt like I was pushing so hard, and everything felt so slick down there, it was barely sliding in. I looked up and could see Cathy wincing in discomfort. “It won’t fit… it won’t fit…” she muttered.
Now, I wasn’t about to stop after getting this far, so I pulled back a little bit and then pushed in hard again. This time, I felt something give and suddenly most of my cock slid deep inside. Cathy screamed out at the penetration. “Are you okay?” I asked, buried inside her, but not moving.
She lay there, looking back at me. Her breathing became more regular. “It fits,” she said, smiling at me. “It really hurt when you went in, but it’s better now. I feel so full!” I was marveling in the sensation myself – it felt so warm and tight inside her. I could feel a squeezing sensation and it seemed to undulate when she moved or talked.
It looked like Cathy had recovered, so I slowly pushed back and forth. The sensation of my cock sliding in and out of her felt so intense. Very different from when I touched myself. I could tell that Cathy was similarly overwhelmed, as she started moaning and rocking in time. “I had no idea it could feel so good,” she gasped.
It was getting easier to move in and out. It felt like her insides had loosened up a little for me. I started moving faster and Cathy wrapped her legs around my back, pushing me deeper and deeper with each thrust. As the pace increased, I could feel that familiar tingling in my cock and I knew it was time.
I gave one final push deep inside her and felt a large jolt as my cock squirted a large jet deep inside her. “Oh!” Cathy started as she could feel the twitching. I gave another push into her and another twitch marked a second squirt of my juice into her. A third push and a third squirt followed. At this point, I was just resting as deep inside her as I could, feeling the remaining pulses of my cock deliver the last bits of cum into her waiting womb.
Cathy kept moving underneath me, thrashing about. I could tell that her moment came, as she was moaning and panting, while thrusting her pelvis up at mine, trying to get my cock even deeper inside her.
We just lay in each other’s’ arms, letting the sensation of our orgasms pass. I had never felt anything so intense before and I don’t think Cathy had either. “That was wonderful,” she said to me. “We have to do this again.” I couldn’t agree more.
Then we both heard a voice from above us that put the shock of reality back into us. “What have our little brother and sister been up to?”
