There were only two days left at camp, but only one full day. The next day we would leave in the afternoon.

Jenny's parents and my parents had planned a day trip to visit some local places. I think they just wanted adult time away from the kids before the Summer was over.

In the morning, both families gathered in our camp for breakfast. Once we finished eating, our parents got dressed for their trip. Carrie, Jenny, and I prepared to hit the beach again, and maybe a hike later. Jake showed up as we were getting ready.

My parents were dressed and ready to go just as we were about to head for the beach. Jenny's parents came back over, and the adults explained to us where they were going, and said they would be back in the late afternoon.

Jenny's mom reminded Jenny and Carrie that they hadn't put on sunscreen yet, and Carrie assured her mom that they would do that at the beach. Sunscreen was an everyday essential at camp. A few years before, I didn't follow instructions and dared to spend the entire day in the sun without sunscreen. I paid a big price, with a sunburn on various parts of my body, including very sensitive ones. We didn't fight our parents on that issue.

The adults left in my parents' car, and we were off to the beach with towels and backpacks full of water, sunscreen, and snacks.

We decided to climb over the hill and set up at the smaller part of the beach, where there were less campers. We laid out our towels. Jenny and Carrie were on the inside. Jake was next to Carrie, and I was next to Jenny. There were only a few people on the small beach, and they were pretty far away from where we set up.

"Sunscreen," Carrie announced to Jenny.

Carrie unzipped one of the backpacks and pulled out their sunscreen.

Jake and I had already put some on at our own camps, so we were fine. It was customary for you to ask someone else to put sunscreen on your back, so the girls agreed to do that for each other.

But then Carrie looked over at Jake, who was on his back on his towel. The rest of us were still sitting up on our towels.

"Do you want to put this on me?" Carrie asked him.

Jake looked up at Carrie and smiled.

"Sure," he said.

Carrie handed him the bottle of sunscreen and laid face down on her towel.

Jenny then looked over at me, smiled broadly showing her braces, and shrugged her shoulders with a sort of questioning look on her face.

"You want me to put sunscreen on you?" I asked.

"Yeah," Jenny responded.

Jenny laid face down on her towel next to her sister.

By that time, Jake was up on his knees straddling the back of Carrie's hips. He reached down and picked up the bottle of sunscreen, as I got up and straddled the back of Jenny's hips. Jake squeezed out some lotion on his hand, then handed me the bottle. I did the same, putting the bottle down between the girls.

Jake started rubbing the lotion on Carrie's upper back and neck. I did the same on Jenny. Jake grabbed the bottle for more, and then handed it to me. We moved down their lower backs and then their butts. I could feel my cock start to fluff as I rubbed the lotion on Jenny tight little butt cheeks, but I did not want to get an erection, so I tried to think of anything other than sex.

Jake and I worked our way down the back of the girls' legs. When we were finished with their backs, Jenny and Carrie flipped over. Jake and I moved up into position again, this time straddling the front of their hips. For some reason, the sight was stunning to me. I'd seen them both naked many times, but sitting in that position, looking at their gorgeous bodies, pink erect nipples, and pussy mounds with light brown hair, was erotic. My cock started to fluff again. I swallowed hard as Jake handed me the lotion. We started at their shoulders and arms.

The next round of lotion led to their breasts. I rubbed lotion on Jenny's breasts, which were almost non-existent when she was on her back, but also glanced at Jake massaging lotion into Carrie's boobs, which were a nice handful for him. My cock was now half erect and sticking straight out. I didn't dare look over at Jake to see if he was having the same problem. I didn't want him to look over at me. The girls had their head backs and eyes closed, so they couldn't see anything.

We moved down and rubbed lotion into their tight firm bellies, pussy mounds, and hips. This didn't help my erection, which was nearly full. Then Jake and I moved down and put lotion on their legs.

"Inside of your legs," Jake said to Carrie.

Carrie moved her right leg away from her body, bending her knee, exposing her inner hips and her pussy for Jake's viewing pleasure.

"Jenny," I said.

Jenny did the same, except with her left leg. I now had a great view of Jenny's pink pussy. My penis was hard as a rock.

Jake handed me the sunscreen bottle one last time. I rubbed lotion on Jenny's inner hips, as Jake finished up with Carrie.

I finished rubbing sunscreen lotion on Jenny's body as Jake moved back over to his towel. I couldn't help but notice that Jake's cock was not hard, which made me even more self-conscious about having a full erection.

As I moved back over to my towel, Jenny moved back over onto her stomach. As she did, she spun to her left and glanced at me. I thought she might have seen my erection, but I wasn't sure. I laid face down on my towel, hiding my hard cock.

"Thanks," Jenny said to me.

I flipped my head toward her. She looked at me and smiled.

"Sure," I said.

"Roll on your side," Jenny instructed in a whispering voice, a smile still on her face.

"What do you mean?" I asked, pretending not to understand what she was directing.

"Roll on your side and face me," Jenny said in a whisper.

I reluctantly did as she instructed, exposing my hard cock to her view, if she looked down. She didn't. She just reached out with her right hand and wrapped it around the shaft of my fully erect penis.

"We'll take care of that later," she whispered.

A broad smile exposed her braces again.

Jenny let go of my cock, put her hand to her side, and turned her head toward her sister.

I sighed and rolled back onto my stomach.

About five minutes later, just as my cock was back to normal, I saw Carrie and Jake get up.

"We'll be back in a while," Carrie announced.

Carrie and Jake walked off, hand-in-hand, toward the hill leading to the bigger part of the beach and the campground. I turned my head to the right and watched them walk off.

"John," Jenny said.

I turned my head back toward her.

"They're going to have sex," Jenny declared.

"How do you know?" I asked.

"I heard them whispering," Jenny replied. "They're going to our trailer."

"Oh," I said.

"Do you want to go to your trailer?" Jenny asked.

Jenny didn't have to spell it out.

"Sure," I said.

Jenny and I got up and followed the direction her sister and Jake had just went, leaving all four towels on the beach, and our backpacks as well. Just like Carrie and Jake, we held hands as we walked across the beach and back to camp.

Once Jenny and I were in my trailer, she looked around. She had been in our trailer before, but it had been a while. It was very small compared to her family's big Airstream. Jenny spotted the bed at one end.

"Is that where you sleep?" Jenny asked.

"Yep," I replied.

"Come on," Jenny instructed as she went over to my bed.

Jenny climbed onto the bed, which was basically a flat square with a thin mattress and sheets. Under the bed platform were storage cabinets.

She rolled over on her back and smiled at me. I climbed on the bed and positioned myself on top of her, straddling her hips with my knees, like I had done earlier on the beach when I was putting sunscreen lotion on her body.

I kneeled down and we kissed. Then I moved down Jenny's body and gently sucked her left nipple into my mouth. Jenny breathed heavy and moved her hands to the back of my head.

I moved to Jenny's right nipple. As I did, there were distinct noises coming from the window near the bed. At first I was alarmed and looked up, and then at Jenny, who was also looking toward the window.

But then we both realized the source of the sounds, as we had heard similar sounds before. It was the slapping and moaning sounds of Jake fucking Carrie, this time in the trailer in the camp site next door. Their sounds of sex were travelling out their trailer window in and into ours.

Jenny and I smiled at each other, then I got back to business. I scooted down Jenny's body, but there was very little room, even with Jenny's diagonal on the bed. I scrunched up against the trailer wall, with my knees against my chest, and buried my head in Jenny's crotch. She assisted by pulling her legs back and holding the insides of her knees with her hands. I put my hands on the back of her hips as I started to lick up and down her pink pussy slot.

"Mmm," she moaned softly.

I glanced up as I continued to lap at Jenny's pussy. I resumed my concentration on the cunnilingus. Because of the position of our bodies, Jenny could watch as my tongue moved up and down her pussy slot, and then concentrate on her clit. Jenny's breathing got even heavier.

We faintly heard Jake say something about 'cum,' and then moan repeatedly. I was pretty sure he was ejaculating into Carrie's mouth again. Jenny and I looked at each other.

"Do you want to fuck me now?" Jenny asked.

I pulled my face away from her pussy.

"Not yet," I said.

I wanted to make Jenny cum again. Plus I knew that if I fucked her right then, it would only last a minute or so, and I wasn't ready for our sex to be over.

Jenny continued to hold her knees, pulling them back to her sides, keeping her body tight and spread. I increased the pace and force of my tongue lashing over her clit, still holding the bottoms of her hips with my hands.

A few moments later Jenny started to gyrate her lower body.

"I'm gonna cum," Jenny whispered.

Her pussy muscles started orgasmic contractions, as she continued to watch me lap at her clitoris. After a few more contractions, Jenny's clit was too sensitive for me to continue. She jerked her hips a bit.

"Okay, okay," Jenny hissed. "Fuck me now."

That time it wasn't a question. It was a command.

I raised my upper body, spread my knees, and scooted my hips underneath and to the side of Jenny's hips, which were still pulled back and spread by her hands.

My hard cock was pointing straight up, so I had to use my hand to bend it down. I rubbed the tip up and down Jenny's wet pussy. She watched it all. Then I pushed the head of my hard penis into Jenny.

The feeling was amazing. Tight and wet. I pushed further into her pussy, as both of us watched. I looked up at Jenny, and she looked back at me, her mouth open. I gazed back down at the sight. Jenny inner pussy lips were stretched tight and wrapped around the hard shaft of my cock.

I began a slow rhythm with my hips, fucking Jenny with most of the length of my penis.

I realized that looking at the action was only going to make me cum fast, so I looked up again, but that was no help. Jenny's hard nipples and her cute face, glancing back and forth between my own face and the fucking action, meant I was not going to last more than a minute or two.

"Cum in my mouth," Jenny said in between breaths.

I nodded. But it was too late. I was already on the verge of orgasm, and the position of our bodies was difficult.

I pulled out quickly and grabbed my cock with my right hand, trying in vain to delay my orgasm.

"Ohh," I moaned.

The fist jet of semen flew out of my cock, straight out into the air above Jenny's body. The furthest drop hit the wood paneling above her head. The rest of the stream of cum landed in a string from Jenny's forehead, down the inside of her left eye next to her nose, and down her left cheek. Jenny immediately flinched and closed her eyes.

The second burst of cum hit her chin, and left a string of semen on her neck and upper chest. By this time I was stroking my cock through the rest of my orgasm.

The next few shots of cum landed on her chest between her nipples.

I was breathing hard, and more cum sputtered out, landing just above Jenny belly button.

Jenny opened her right eye and looked down at my cock as I squeezed the last of the cum onto her belly.

"Geeze, John," Jenny said.

"Sorry," I said.

Jenny laughed.

"It's okay," Jenny reassured. "But can you get me something?"

"Sure," I said.

I scooted off the bed. Jenny let go of her legs as I went for a hand towel in one of the drawers near the sink.

Jenny was laying there, with my cum all over her face, chest, and belly, with only her right eye open. I handed her the towel. She wiped the cum off her face, and then wiped the strings of semen from her belly and chest.

Jenny sat up on the bed.

"At least you didn't cum in me," she declared.

I nodded. I reached out for the towel, which Jenny handed to me, and used it to wipe up the small amount of cum that had dripped down the paneling next to the bed. Jenny turned and watched. She just shook her head and laughed.

After we left my trailer, Jenny and I walked back to the small part of the beach, where we found Jake and Carrie laying on their towels.

Nobody asked anybody where they had been.

We had a good time at the beach for a couple hours, swimming, talking, and laying out on our towels.

Later, we headed back to camp. Our parents were there, and we discussed their day trip adventure.

It was mid-afternoon, and Carrie announced that she and Jake were going over to his camp for a while. Jake had Carrie's backpack on, and I couldn't help but notice that Carrie was wearing her hiking boots instead of the usual sandals. But I didn't think anything more of it.

A short while later, Jenny pulled me aside.

"Jake and my sister didn't go to Jake's," Jenny said.

"Oh," I replied. "Where'd they go?"

"Up to the landing," Jenny answered.

"What for?" I asked. "Are they going to do it again?"

"No," Jenny declared. "They're waiting for us."

I asked Jenny what she meant, and she explained. Jenny told me that she and her sister had talked after we got back to camp earlier that afternoon. Carrie had told Jake everything, including Jenny and I watching them have sex. Jake asked Carrie to set things up in reverse, without me knowing. But Carrie and Jenny agreed they would tell me anyway. But I needed to pretend I didn't know. The plan was for Jenny and I to go up to the landing and have sex, while Jake and Carrie watched from behind the tree that Jenny and I had used to watch Jake and Carrie. It was kind of strange, but I agreed. Jenny said they were waiting.

So I announced to our parents that Jenny and I were going for a hike, and we would be back in a couple hours. We got on our hiking boots, and I put on Jenny's backpack with towels and water.

As we trudged up the trail to the landing, Jenny explained further. Carrie had an ulterior motive in helping to set this up. Jenny had told Carrie how I licked her pussy long enough to make her cum. Carrie told Jenny that Jake didn't do that, but Carrie really wanted him to try. So Carrie thought that if Jake watched me do that to her sister, Jake might get inspired. It started to make a little more sense.

When we got near to the landing, Jenny instructed me that I was not to look toward the tree on the hill where we had hid the other day. I agreed.

Once we got to the landing, Jenny took her backpack off me, and set up our towels end-to-end on the landing. Then she summoned me to her towel. We kissed.

My cock didn't respond as quickly that time. I wasn't sure if I was just nervous about the situation, or if it was because we had sex a few hours earlier, and I had a major orgasm. In any event, Jenny didn't seem concerned, so I didn't worry about it.

Jenny got down on her towel, face up, with her head away from me. I crouched down onto my towel as she spread her legs, giving me a great view of her pink pussy. I laid down on my stomach, put my hands on the insides of Jenny's hips, and planted my head in her crotch. Unlike earlier in the day in my trailer, I had plenty of space. It was fun.

I started gently licking the lower part of Jenny's pussy. I decided to go really slow, partly so that it would last a long time, and partly to put on a show for Jake and Carrie.

I lapped at Jenny's pussy slot for a few minutes. I glanced up occasionally and saw that she was just laying back and enjoying the feeling, with her head fully back, not looking at me or up the hillside.

I eventually worked my way up Jenny's inner pussy lips to the spot where they joined.

Jenny sighed.

As I gently licked at Jenny's clitoris, she put her hands on the back of my head. I increased the speed of my tongue flicking over her clit. She responded by pulling my head harder onto her crotch, causing my mouth to fully cover the upper part of her pussy. I put more pressure on her clit with my tongue, causing Jenny to gasp and gyrate her hips, still holding my head tight against her.

"Ohh," Jenny called out in a breathy voice.

She looked down at me, holding my head steady against her crotch, as her pussy and lower body twitched in orgasmic contractions.

By using her hands on my head, Jenny controlled the stimulation of her clit, causing her orgasm to continue longer than ever.

When she could take no further direct stimulation, she pushed my head away from her body and looked at me, my mouth saturated with her wetness.

"Fuck me," she said softly.

I nodded. I forgot about my own cock during the cunnilingus, but now realized it was fully erect and ready.

I scooted up to face Jenny, as she reached down, grabbed my hard cock, and positioned the head of my penis to enter her tight, warm, and wet pussy. I pushed my hips forward.

My cock sank into Jenny as I looked down on her face, holding my body above her with my arms. I felt a surge of pleasure.

Jenny reached her hands up to the sides of my face and pulled me down to her. We kissed.

I gently fucked Jenny as we continued to kiss. Then I moved my mouth to her neck, and nibbled as I continued to pump my hard cock in and out of her.

I was determined to last longer, so I concentrated my efforts on making sure the timing of my pumping into Jenny reduced my chances of reaching the point of no return. I totally put out of my mind the fact that Jake and Carrie were watching every move.

"I want you to cum in my mouth," Jenny whispered in my ear.

"Okay," I whispered back.

"Do you want to do me from behind?" Jenny asked. "That might make it easier."

I lifted my body up and of Jenny, and pulled my cock out of her pussy.

Jenny turned over and got onto all fours, exposing her gorgeous ass and pussy. I immediately lined my cock up against her, and pushed. I watched as my cock disappeared into Jenny, her pussy lips tightly wrapped around the shaft of my erect penis.

I fucked Jenny more vigorously, slapping my hips up against her ass on each stroke. I knew I wouldn't last much longer. I moaned.

I pulled out of Jenny again, and she immediately spun around, grabbed the shaft of my cock with her right hand as I stayed on my knees, and leaned down.

As Jenny put the head of my cock into her mouth, I exploded.

Spurts of semen blasted into Jenny mouth as I put my hands on her head.

"Ohh," I moaned, as my orgasm continued.

Jenny kept working my cock until I was totally drained. I used my hands on her head to guide Jenny in providing the best level of stimulation.

When I was done, I pulled my cock out of Jenny's mouth and sat back on my feet. Jenny leaned forward, and we kissed again.

Then we stood up, embraced, and kissed some more.

After that, we packed our towels into Jenny's backpack and headed out of the clearing.

On the way down the trail, Jenny told me that was the first time she had more than one orgasm in a day. I told her that was the same for me. She smiled.
