"It'll be fun," my brother Nick told me over the phone, "and Kristy and Karly really want you there."

I didn't care what my brother or his wife Amanda or his two rugrats wanted. I wasn't into camping.

"It's a great time to spend as family," insisted Nick. "We hardly see each other."

I rarely saw Nick or his family because we lived over 500 miles apart. He had his nice suburban life of a wife and kids and I had my nice city life of a divorced bachelor. My marriage lasted less than two years and I swore I'd never do it again.

"We can spend a whole week together," he continued.

It wasn't the spending a whole week with Nick and his family that was the problem. Well, it wasn't the whole problem. I loved my brother even if I didn't make much time to visit him, Amanda, and the kids. The main problem with the idea was they wanted to spend the week camping. Camping!

Aargh! I knew they couldn't afford a week in Vegas or a fancy hotel somewhere else. Hell, I couldn't afford to do that either on my pharmacist's pay but camping? Camping?

"The girls haven't seen you in forever," Nick said in successive persuasive attempts.

"Nick..." I said.

"Come on, Mike," he insisted.

Dammit! Somehow I said, "Yes."

Nick immediately yelled back and I could hear the happy hollering of three females through the phone.

How long would it take their two daughters to whine? Two hours? Next time I went to Vegas I would check if 'girls whining while camping' was on the betting board.

I rented an RV. Okay, it was probably no cheaper than a hotel but Nick and family decided on camping and I damn sure wasn't going to spend my nights freezing my ass in a stupid ass tent or trying to cook breakfast on a candle-powered camping stove or whatever the hell powered those things. Solar power?

Nick arrived the day before and reserved a camp site for me right next to theirs. I chose a small RV because it was only me and I didn't want the concerns of driving some big behemoth. I backed into the spot easily.

Nick and Amanda were immediately there to greet me along with two girls I didn't know. Maybe they brought neighbor girls along. They were that kind of people. What was the word for them? Nice? Friendly? Something odd like that.

"Mike," Nick greeted me with a firm handshake. "Glad you made it though you're hardly roughing it." He looked my RV over.

I held back any comments. Just be glad you got me out here, brother.

I hugged Amanda and we exchanged pleasantries.

"Uncle Mike!" greeted the taller blonde girl and she hugged me.

I reflexively hugged her back. Uncle Mike?

I separated from the girl and looked into her face.

It couldn't be! Could it?

"Kristy?" I ventured out.

"You didn't recognize me?" she said in surprise but she didn't sound offended.

I looked at the younger blonde girl. Karly? How long ago was it?

I looked back at the original blonde girl. Damn! She was more a woman than a girl.

"How old are you?" I asked to get some bearings.

"Seventeen," Kristy responded.

Wow! When did Nick's girls grow up? Kristy was quite a young woman with her long blonde hair and svelte body.

When she turned around I saw how she filled in her tight jeans. That was an awesome ass!

Shit! My cock stirred.

"Uncle Mike," said Karly more tentatively.

I hugged the young teen.

"So how old are you now?" I asked the other blonde.

"Fourteen," she said.

Karly was maybe a little chunky. It was hard to tell with her shirt hanging over her hips. Puberty would hopefully spur her into a beautiful young woman like her gorgeous sister.

I looked over at Kristy again. Damn! I couldn't keep my eyes off my niece. Fuck! I had a hard-on because of her. That was so not right but what could I do?

Nick and his family were situated in two tents that they had to place on opposite sides of their campsite since that was the only areas that would fit both because of the fire pit and a couple of trees. Kristy and Karly slept in the tent closest to my little RV.

Amanda created for dinner steak-and-potatoes-wrapped-in-aluminum-foil packages that were cooked in the campfire. She made one for me too. I would have gladly volunteered my RV kitchen to cook dinner however the food was surprisingly good.

I was very impressed. Later they heated marshmallows over the fire and made smores or moors or something. That was another pleasant surprise.

We made a lot of small talk then moved on to 'catch up on life' talk. Kristy was about to be a high school senior and Karly was going into the ninth grade. Nick was now the director of his department which provided the money to extend their vacation to ten days. I received immediate urgings to extend the extra few days but I just said, "I'll see."

I begrudging had to admit I enjoyed myself in conversation around the smoky campfire but there was one big problem. I struggled mightily not to stare at Kristy. She looked amazing. I spent much of the evening shifting uncomfortably in the camping chair trying to find a placating position for my hard cock. Why was I jonesing for my niece so badly? She was my brother's fucking daughter of all things! How the fuck could I be horny about her?

It was maddening!

I was dead tired when I headed to my RV. I brought various drugs with me in case of injury or sickness or whatever I thought I needed. I included stuff to help me fall asleep but I didn't need anything to help me enter dreamland tonight.

It was cold that night so I was very, very happy to sleep in my RV away from the wind and chills instead of the tents they had to sleep in.

Would you believe it? Amanda had eggs and bacon cooked on the propane stove even before I came out the next morning. Either they were much more talented than I gave them credit for or else IHOP delivers to the forest these days. It was so delicious I wondered if the truth was the latter.

"Are you ready for today, Uncle Mike?" Kristy asked.

"I guess so," I replied. Time to kill one more camping day which meant I was one day closer to going home.

"Good. It's going to be fun."

Uh-oh! It sounded like she referred to something specific.

"What's going to be fun?" I asked. I didn't really want to know but I had a feeling it was in my best interest to find out.

"The hike."

"Hike?"

"I'm sorry," interjected Nick. "I forgot to tell you.

I thought we'd hike up to the top of the hill."

I followed his pointing finger. Up that hill? It would take a couple of hours!

"There's a nice little trail," said Nick.

"It's a decent workout," added Amanda.

Kristy must have read the reluctance on my face because she said, "Come on, Uncle Mike. You'll like it."

"If you want to stay alone..." said Nick giving me an out.

"Please," pleaded Kristy. "We haven't seen you in years."

"Alright," I said.

She smiled big.

I was sure I would be determined to say 'no' if not for Kristy. The hike meant that I would spend most of the day with her. I felt very bad about my lust over her but I was dealing with it and knew that it was going to be a fact of life this week.

Kristy was energetic on the hike so she surged ahead.

She had changed into shorts before we left so I got to watch her tremendous ass and slender legs during the whole walk up. I tried not to imagine my cock deep in her pussy with her legs wrapped around me because a hard-on was a detriment to my walk.

The top of the hill wasn't the top of the hill. It was just what one could see from the campsite. When we got to the top we walked on a more level area deeper into the trees. The campground was out of view so I trusted that they knew where we were going.

"You're going to like this," said Amanda to me. "It's beautiful."

Somehow I didn't think she meant a big bed, silk sheets, and a young naked woman pampering me by sucking my cock. That would be so beautiful.

We walked on a couple more minutes. I could hear a sound increasing in volume as we neared it.

"Close your eyes, Uncle," said Kristy.

"What?"

"I want you to see it all when you first view it."

Damn girl! Don't talk like that! You make me think of you as the woman in my fantasy.

I closed my eyes and Kristy and Nick guided me several more feet. I could hear the roar clearly now of whatever we were near. A river?

"Turn him a little to the right," said Amanda.

I was adjusted. No, not there.

"Go ahead," said Kristy.

I opened my eyes and before me was a picturesque waterfall straight out of a postcard or a TV nature show.

"It's beautiful," I said. I wasn't that impressed. It was nature after all. If a tribe of horny and topless tree nymphs lived next to the waterfall then that would be impressive.

"We go up here everytime we go camping," Nick said.

"Eight straight years now," said Amanda.

They've gone camping at this place for eight straight years? Eight? There was no room service. There was no masseuse. There was no randy young buxom beauty to rub her tits all over my face.

"Can we go in now, Dad?" asked Karly.

"Sure," Nick answered and nodded.

I looked around. Okay, it was a gorgeous spot. It was a small waterfall surround by lush trees.

My eyes stopped on Karly. She was handing her shirt to Mom and was in a bikini top. My eyes focused beyond Karly when I saw Kristy lift up her shirt. In moments, Kristy was only in a bright yellow and black bikini and Karly was in a light blue bikini outlined with pale yellow.

As the girls walked toward the waterfall, my eyes first gravitated to Karly's ass. She was slightly chunky as I suspected but a growth spurt would make her ass perfect. I stepped to the right so I could see Kristy better. What a fabulous small tight ass! The bikini bottom was a little too small so the sides of her cheeks were exposed plus the fabric bunched into her crack. I could easily see the outline and shape of her ass.

My mind gravitated to a fantasy of Kristy on her hands and knees as the waterfall sprayed over her while I happily and wonderfully thrusted inside her pussy. My hands caressed over her perfect ass. The sensation of her skin was amazing.

Speaking of amazing, I had an amazingly hard cock right now. I couldn't remember having such a strain in the longest time.

The girls ran into the cold water and immediately shrieked.

"The girls always want to be able to say each year that they showered in a waterfall," explained Amanda.

It wasn't worth it. No fucking way was it worth freezing your ass off just to say you bathed under a natural shower. I was about to say they were crazy when my eyes grew large. I could see Kristy's hard nipples because of the cold water. It was worth it after all.

For me.

Kristy's tits appeared to be about B size. That was perfect for her. Anything larger would look too big on her lean frame.

I thought about going into her tent tonight and taking her. She would be so delicious.

There were a couple of large rocks I hadn't noticed until the girls spread out on them to dry in the sun.

I talked with my brother and Amanda until Nick excused himself to relieve his bladder behind a bush. I decided to take the opportunity to do the same thing and I headed in the opposite direction which was toward the dormant girls. When I finished, I was part way back when I noticed I could stay hidden from Nick and Amanda yet I could watch Kristy. She lay with her eyes closed.

I looked at her lovely wet blonde hair and gazed over her pretty face. Beneath those eyelids were beautiful blue eyes. Those lips looked very kissable and would look wonderful wrapped around my cock. I lowered my eyes to her seductive neck and to her tits. I could no longer see her nipples but the sight was still fresh in my mind. I imagined her tits in my hands. I thought about sucking in deeply her boob flesh into my mouth. My eyes lingered on her flat tummy. How would it feel to my touch? My eyes reached her pussy but I decided I would come back in a second to her special place. I travelled down one leg and then up the other. I returned to her pussy. Could I see a little lip outline or was it my imagination? I'd go closer if not for the fact Nick would see me ogling his daughter. So much for improving family relations.

"What are you doing?" asked Kristy.

I lifted my eyes. Shit! She was looking straight at me. For how long did she look? I dared not ask.

"Uh... , " I stammered. "I was using a bush." Why did I say bush?

"You seemed deep in thought."

"I have a lot on my mind," I said.

"Like what," she asked. "What do you think about?"

I wasn't going to tell her I thought about cramming her little cunt full of my cock meat.

"Grown up stuff," I said.

"I'm almost eighteen," she said. "I'm almost an adult."

"You have years to think about such things," I said. "Enjoy yourself."

"Do you have a girlfriend?" she asked.

Now where did that question come from?

"Not right now," I said.

"But you did?"

"Yes but not for a while."

"You get lonely?"

What was all this? Was she going to grow up to be a shrink?

"I'm happy with my life."

"You sure are different than Dad."

"How so?"

"He married Mom right out of college and they've been married almost twenty years while you've been single forever."

"I was married but I divorced. I'm the irresponsible younger brother."

"You're only three years younger," protested Kristy.

I laughed then she got the previous joke and laughed too.

She finally said, "I wish you had kids so we could have cousins to be with."

I didn't need kids. I had something better for her to be with. I was sure that wasn't what she was thinking about.

"We should head back," shouted out Nick.

Kristy woke Karly. The girls dressed and we headed down. I once more had the pleasure of watching a cute ass for a couple of hours. Karly's wasn't so bad in my mind either but she only had the vestiges of womanhood.

By the time we got to camp, my cock was hard up for release and my mind was astir with ideas of how to do it that didn't involve masturbation. My thoughts were drawn more and more to Kristy as the source of my release.

I excused myself from dinner and said I needed to rest after the hike because I was out of shape.

In my RV, I pulled out all my drugs. I grabbed cups and spoons for mixing.

Why wouldn't it work?

I waited until night. I aroused when my cellphone alarm went off at 12:30 AM. My cock was already aroused. I applied skin ointment to my face that I earlier darkened with ibuprofen tablets. I pulled on a hat and made sure my hair was completely covered.

I was only in my underwear and I would be cold when I stepped out but I didn't intend to be dressed for what I planned.

I opened the RV door as quietly as I could to let air inside. I poured a mixture I made earlier onto a dishcloth. This was my risky venture but I felt certain I did it correctly. No harm would come from it.

I walked quietly in the cold to the girls' tent.

I didn't know if my shivering was due to the temperature or the action I was about to undertake.

I unzipped the small tent. It sounded too loud but I saw none of the girls stir in the dim light. It took me a moment to ascertain that Karly was on the left. I stepped carefully between the girls and got down on my knees. I slowly turned Karly's face toward me.

I struck!

I held the dishcloth over Karly's face while simultaneously pinching her nose closed. She gasped out and took two or three deep breaths. She struggled weakly. Maybe it was more of a twitch. Her eyes might have briefly fluttered open in a non-discerning manner and then she stopped.

I checked her pulse. She was fine. Karly was asleep again and now there was no chance of her waking up for a couple of hours. She wasn't just asleep. She was unconscious.

I tossed the towel out of the tent. I'd pick it up later. I didn't want the fumes possibly disorienting me. I zipped up the tent and I was in the pseudo-privacy it provided. Who knew if another camper or even Kristy's parents might get up during the night? I knew it wasn't the slightest bit soundproof but I was out of sight.

I stood and grimaced. My calves were sore from the hike. Maybe I should have waited one more night but my desire was too great. I stepped over Kristy so I was on the zipper side of her sleeping bag. I unzipped Kristy's bag and opened it up.

WTF?

Kristy was topless inside her bag. I couldn't see the full beauty of her tits but I could definitely see she wasn't wearing a night shirt.

WT-bigger-F?

She was ... she was naked!

Fucking shit! Unbelievable. Completely unbelievable.

This would make things way better. There were no risks of her waking as I undressed her and no need to threaten her to make her undress.

I took my shorts off and threw them toward the door. I got down at her feet and slowly pulled her legs open. I couldn't see much of her pussy in the darkness but in my mind I could smell it. She was dead to the world and didn't stir.

Soon she would stir.

I hovered over her so only my cock was on her. I slid over her pussy and she breathed out sharply. I found what felt like approximately the right position. I pushed forward. My cock slid down slightly but it was an angle correction so I knew I was at her opening.

I took a deep breath and I punched in.

Kristy's body shook in response to the sudden invasion.

I pushed deeper and deeper until my cock was completely inside her sweet tight pussy.

Fuck yes! I was fucking my beautiful niece.

My cock throbbed excitedly inside her cunt as I lay on top of her.

There was a sudden if not unexpected gasp beneath me.

"Shh!" I cautioned in a disguised whispered voice. "I won't hurt you or your sister if you stay quiet."

She didn't respond which was a good sign.

"Just a little fun fucking," I said.

I began to stroke inside her. I can't describe how wonderful it was to fuck her young tight cunt. It was immediately the best fuck of my life.

"So fucking good," I said and immediately hoped I didn't sound too much like her Uncle Mike.

I fucked Kristy. I took my time because I wanted this experience to last as long as it could. Tomorrow she would declare that she was raped during the night and her Uncle Mike, who was asleep in his RV, would say he didn't hear anything. I wouldn't get a second opportunity to fuck Kristy.

Anytime I felt build up toward ejaculation, I stopped inside her and let the sensations subside so I could last longer. I don't know how long I fucked her but it may have been ten or fifteen minutes.

I finally came to the point where I couldn't hold back any longer. It was the end of this awesome experience. I thrusted faster until I pounded hard into her cunt. I groaned but I didn't care who heard outside the tent. I needed to cum.

Kristy surprised me when she moaned frequently in response to my hard thrusts.

Then I was really surprised.

Kristy moaned out, "Yes, fuck me, Uncle Mike!"

Normally there would be nothing that would knock me out of my rhythm when I was that close to cumming. I would continue to plow that pussy until seconds later I shot my white bubbly goop.

"Yes! Yes!" she moaned louder. "Uncle Mike. I love you inside me."

Hearing my niece shout my name as I fucked her changed that. Shit! She knew it was me!

"Oh, Uncle Mike! Yes!" she cried out. My cock was still hard and throbbed violently inside her.

How was I going to explain this to Nick? Would he strangle me or was my fate to be the future 'prison bitch' to Fat Eddie?

"Don't stop!" she said.

Wait a minute!

"Kristy?" I hesitantly said.

"Fuck me, Uncle Mike," she exhorted. "You feel so good inside me."

"You knew it was me all along?" I asked.

"You couldn't keep your eyes off my ass the last two days. It had to be you."

"Oh..." I said feeling stupid. "I'm ... I'm sorry."

I knew an apology was a lousy way to make amends for rape.

"For what? Sex? Why do you think I was naked? I thought you were going to come for me last night?"

"You ... you want me?" I asked incredulously.

"You're handsome," she explained, "and the way you looked at me I knew you were interested too."

I wondered what she thought about the uncle - niece aspect of this, but then I decided I didn't want to know. What good would it do? It would only make things potentially messy.

My cock throbbed to regain my attention.

I started my thrusts up again.

"Oh, yes," she responded. "You feel so big."

My sensations accelerated quickly and so did Kristy's.

We rapidly approached orgasms.

Kristy chanted, "Yes!" with increasing vigor until finally she went quiet, tensed up hard, and then exhaled deeply while becoming as relaxed as boiled spaghetti on a campfire stove.

I was moments behind.

"Kristy," I said in a hard whisper and grunted roughly. I shot stream after stream after stream of cum into her teenage twat. I can't remember ever cumming harder even from my youth.

"Oh, yes," she hissed as I filled her cunt with cum.

We lay gasping for several minutes while eagerly we kissed.

Kristy turned her head and looked at the sleeping Karly, "What did you do to her?"

I explained.

"So she's okay?"

"Perfectly," I assured.

We talked about tomorrow night. Kristy would wait until Karly was asleep then come into my RV. It was more private and more importantly it was out of the cold.

The next day was relaxed with no activities planned.

Kristy couldn't keep her eyes off me as much I couldn't do the same with her. We took a couple of short walks along nearby trails but Karly was always a tagalong, so we couldn't kiss let alone grope. It was probably just as well because I'd probably try to drop her to the dirt and fuck her right there. I'd for sure get caught then. After sticking my cock in her once all I could think about was doing it again.

After dinner with darkness beginning to fall, I managed to talk to Kristy quietly.

"I'll leave the RV unlocked with the door slightly open so it doesn't make too much noise. The lights will be out so everyone will think I'm asleep."

"What if you fall asleep?" she asked.

"You'll have no problem waking me."

Kristy giggled softly.

"What if you fall asleep?" I asked.

"I won't," she said.

"I'll set an alarm just in case," I said. "I'll come out and get you."

"What if Karly wakes up?"

"Then we don't do anything tonight."

She pursed her lips at the prospect. I agreed with her thoughts.

"How dark is it inside your RV?" she asked. "I want to see you."

"Very dark but it's too obvious from the outside if the bedroom light is on," I answered. "Hmm ... but I don't want you stumbling into something and making a racket." I had an idea. "Bring your big flashlight. You use it when you go to the bathroom at night anyway, so it will look normal if Karly wakes up and sees you when you return to your tent. We'll aim the light so we can see each other but so it doesn't blind us. If it can be seen from the outside, people will only think it is a night light."

Kristy smiled and said, "You're smart."

It was amazing how smart I could be when my motivation was to fuck a 17-year old beauty.

"I'm tired tonight," announced Kristy around the campfire at about 8:30.

Everyone said "good night" and she headed off to bed.

I proclaimed my need for sleep about fifteen minutes later. Now was the wait for Karly to go to bed and fall asleep.

In my RV, I stripped and lay naked on my back. My cock was hard and ready. I could not wait until Kristy joined me. I glanced at the clock. Only five minutes had passed. It was unreasonable to think Kristy would be so soon. After several five minute intervals passed, I got up to turn the clock so I couldn't see it because I was driving myself crazy in anticipation. I returned to the bed.

"Uncle Mike?" a voice came.

It took me a second but I recognized the voice as Kristy's. Surprisingly, I must have fallen asleep.

I glanced at the clock. Why was it turned around? I guess it didn't matter what time it was as long as Kristy was here now.

The beam of light came closer and then exposed my foot. Kristy scanned the flashlight up my body.

"Whoa!" she said when she saw my cock. She left the light aimed there. "You're huge."

"You fucked it last night," I reminded her.

"It was in me but I didn't see it. You felt bigger than any guy I've been with but to see it, you look absolutely enormous. Good thing you just stuck it right in me last night or I'd be afraid of it."

The words were flattering but I knew I wasn't extra big. Kristy must have only fucked guys with small cocks.

I sat up and took the flashlight from her. I placed it on a stand and aimed the beam away from the bed.

"It's too dark," she commented.

"Give it a few minutes. Your eyes will adapt and you'll think it is too bright."

Kristy was dressed in sweat pants and a sweat shirt to keep warm during the cool nights. As she continued to eye my cock, she took off her clothes.

After she stepped out of her panties, I said, "Come here."

She crawled on the bed and I guided her forward until her tits were over me. I pulled her down and took a mouthful of right tit flesh. I sucked as much into my mouth as I could while I danced my tongue over her nipple which hardened quickly.

"Ohh," Kristy said in a gasping moan.

I released her tit and said, "I wanted to do this last night but I didn't think I had time." I then enveloped her other tit.

Kristy responded with a hearty gasp.

When I released again, I encouraged her to slide down until our lips could lock in fervent passion.

"Oh, Uncle Mike," she moaned into my mouth.

"You are so beautiful, Kristy," I complemented and it seemed to increase the intensity of her moans but maybe it was coincidental.

She broke away from my lips and slithered down my body. I knew what was coming but it didn't take away from the experience. It was still wonderful when she engulfed my cock in her mouth. She slowly bobbed up and down while lovingly caressing the sides of my shaft with her tongue.

"You're right," she said.

"About what?"

"I can see you easily now."

She plunged her mouth back down and my response was a loud groan and gasp. She was magnificent.

"Kristy," I quietly called out a minute later.

I didn't want her to get me too excited where I wouldn't last very long.

She disengaged and looked up with a happy smile.

"You want me on top this time?" she asked.

"When I saw you at the waterfall in that yellow bikini," I said.

"Drove you crazy," she interrupted.

"I already was crazy for you. Do you know what I thought?"

"I was in the waterfall naked?"

"Too simplistic," I said. "You were on your hands and knees and I was fucking your sweet pussy."

"Does my pussy look like you imagined?"

"Even better," I answered. "Your bikini bottom was too small so it was almost like you were naked. How could I not help but come up from behind and stick my cock in your cunt?"

Kristy turned over and got up on her hands and knees. Her beautiful ass was before my eyes.

"You like it best doggy-style?" she asked.

"With a great ass like yours how else could I fuck you?"

I moved to my knees behind her and caressed her half moons.

"Damn! Your ass feels even better than I imagined."

"You like it?"

"I have a great imagination but to touch you is even better."

"That's sweet, Uncle Mike."

I scooted forward as I smoothed her ass cheeks with my hands. My cock bobbed and then pressed against her pussy.

"Watch it there, mister!" she teased.

I fisted my cock into position and thrusted forward. I slammed into her cunt with one hard push.

"Ahhh!" Kristy gasped out in surprise.

"Oh, fuck, you have a great cunt." Kristy's cunt squeezed around my cock. What an incredible and awesome feeling.

"Aren't you going to fuck me?" she asked as I stayed motionless.

"I'm in no hurry."

I purposefully throbbed my cock.

"Ohhhh," she moaned sensually.

That's my girl.

I stroked slowly in her. I wanted to keep a steady good sensation and prolong the sensation before I was forced to cum. Kristy whimpered softly and slowly thrusted back at my incoming cock.

Conversation was over. The only vocals were the moans and groans of Uncle Mike fucking his niece Kristy in his rental RV. The only other sounds were the wet movement of cock in cunt, the creaking of the bed, and the gentle rocking of the RV.
