I knew that my brother Nick's invitation to join him at the campground had a covert reason. He hoped to restore the relationship between me and him over the ten days we spent together and he had the reasonable knowledge that my relationship with his wife and two daughters would follow along. After leaving the campsite, I can unequivocally say that I felt closer to my brother and his wife, Amanda, than ever before. The reason I felt so close to my brother and sister-in-law was because I became very close to their two beautiful blonde daughters, 17-year old Kristy and 14-year old Karly.

What I cannot say, well, not to Nick nor Amanda, was that I was very close to Kristy and Karly. I was in them. Physically. Okay, I'll say it plainly and directly. My cock was in their pussies almost every night during the camping vacation. Maybe it was just me but my guess was that my brother and Amanda would not be too hot on the knowledge that I fucked their daughters. Again though, it might be just me. What do I really know? I guess because life suddenly said to me 'Go ahead and fuck your sexy nieces' that I became an optimist. Anything could happen. Maybe they'd be okay with it. Maybe. Okay, I'm not optimistic enough that I would actually tell them.

I made sure I called Nick the very next day after I arrived home from the campground.

"Just making sure everyone came home okay," I said to my brother.

"Yeah, nothing happened on the drive home. How was your drive?"

"Good. No problems. I'm really glad you invited me, Nick. I had a great time."

"I'm so glad you came."

Boy did I come! I fucking came and came and came in my two hot nieces.

We made additional small talk then I asked to say 'hi' to Kristy.

"Uncle Mike!" Kristy said excitedly when she was on the line.

"Hey, beautiful," I said. "I miss you."

"Me too! I feel so lonely without you..." She trailed off.

" ... in your cunt?" I finished for her. Our geographical distance didn't allow me to finish in her. Wireless technology had such a long way to go to be truly useful.

"Yeah. I didn't want to say it, you know, while here at home."

"Maybe I can talk privately to you and Karly at the same time and we can have some phone fun?

"Ooooh, kinky. I'd love to but Dad or Mom might pick up."

"We can do it on your cell phones. I'll do a three-way call."

"We don't have cell phones, Uncle Mike."

Of course. Fucking duh! My brother didn't have a lot of extra money. Well, he did have that new job that allowed him to extend his vacation, so maybe he could afford cells for the girls now, but I was sure he still thought like he didn't have the money.

"I want to get you and Karly out here," I said.

"I know. You told us before we left the campground."

"Just want you to know I haven't forgotten."

"It's only been a day."

"I miss you so much," I said.

"I miss ... would you hold a minute?" Kristy said her question with annoyance.

"What?" I said. I could tell the question wasn't directed to me.

"Karly is being a pest."

"I want to talk to her too," I said. I didn't want Kristy hogging the whole time on the phone.

"Oh, alright," said Kristy with irritation in her voice.

"Hi, Uncle Mike!" practically shouted Karly when she came on the line.

"Hey, Karly. How are you doing?"

"I'm terrific. I love you, Uncle Mike."

"I love you too, Karly. How's your virginity?"

She giggled and said, "You have it."

"Oh, that's right."

"You took it. Don't you remember?" she teasingly challenged.

"I remember very clearly that you gave it to me."

"Oh, Uncle Mike!"

"I wish I was doing it again right now," I said.

Karly's virginity was obliterated during the camp experience. Big sister Kristy wasn't a virgin before I fucked her but if she had any remnants that was long gone also.

Karly whispered, "You're making me all drippy."

"I'm already wet," yelled Kristy dimly from the background.

"I told Kristy that I want to get you both out here before summer is over."

"You told us before we left."

"I know. I just want to make sure."

Can't an uncle make sure his nieces know he's thinking about them? That's all I was trying to say. Well, kind of. Sort of. Okay, I was extremely horny. After a week of putting my cock in both nieces' cunt holes each night, I didn't look forward to abstinence or Mister Hand. I couldn't be blamed for feeling that way, could I? I was so desperate that I was willing to initiate phone sex but I guess I wasn't going to get that either. Aargh!

"You girls still on the phone with Uncle Mike?" my brother's voice said.

"Just finishing," I said to Karly.

"Just finishing," Karly said to her dad.

Both girls said a quick good-bye.

"Mike?" said Nick as he came on the line.

"A week wasn't enough with my two nieces," I said. "Lots I want to do to them."

Nick laughed and said, "I hope you mean with them."

Fucking shit!

"Yes, yes," I frantically said. "With them. I am just getting to know them."

Well, not quite. I knew them quite well now. Very, very intimately.

"If I let the girls, they'd run your phone bill to five hundred dollars," apologized Nick.

"Daaaaad," whined Karly in the background.

"I enjoy talking with them," I said.

I contemplated mentioning letting the girls come out to see me. I so wanted to ask now but I knew the best thing to do was wait. I would talk to Nick in a couple of weeks so that way there was no suspicion at all. I didn't think my brother was suspicious but I didn't want to give him any reason to develop any.

I signed off with, "Give Amanda my love, Nick."

I was able to make occasional contact to the girls through email. Kristy said the computer was not private enough to consistently IM. Karly wanted to try IMing anyway but I figured big sis knew better. The girls found a few private moments to check their email and type very provocative replies. My nieces' emails were of great assistance to Mr. Hand's provision of sexual release.

Mr. Hand was still excessively unsatisfactory. Compared to my cock inside Kristy's and Karly's cunts, jacking off was barely better than a urology doctor with a sledge saying, "Hold still. This isn't going to hurt a bit."

My loins literally ached for my nieces. I needed the girls. I had to have them. To be blunt, I fucking had to fuck them again.

I lasted a fucking week before I called my brother.

"Hi, Uncle Mike!" answered Kristy. One could be so clever with caller ID.

"Can I talk to your Dad? I decided to ask him today about you coming to visit me."

"You said you would wait two weeks."

"I know, but if I know when you are coming I can look forward to the day so that there's hope. I am going crazy without you both."

"Hold on a second," said Kristy. I waited silently then she quietly said in baby talk, "Do my Uncle have a big boner? Poor Uncle."

"Dammit, Kristy. Don't do this to me. It takes forever for my blue balls to fucking go down and I practically have them all the fucking time."

"You can't talk to Dad," she said more seriously.

"He's not home?"

"Wait another week."

"Kristy!" I said frustrated.

"You think I don't miss you?" she replied. "I rub myself at night but my orgasms are nothing compared to when we fuck. I want to be with you just as bad. Karly's just as sexually frustrated when she gets herself off. We want to see you, Uncle Mike..."

I interrupted, "I want to fuck you."

"That's what I mean. It will be soon enough. Call back next week."

"Kristy..." I lightly protested. In my heart, I knew she was right. She had more strength than I did.

"I love you, Uncle Mike," she said.

"I love you too," I replied morosely.

Kristy and Karly were flying in today!

They would have a week with their Uncle Mike in the big city and when they returned home it would be a week before their schools started. Kristy was a senior and Karly was a freshman.

When I talked to my nieces a couple of days before they flew out, I asked them to pack light since they wouldn't need much to wear.

Karly gave me an, "Oh, Uncle Mike!" but giggled merrily. She wanted to give me what I wanted as much as my older niece. Karly seemed so grown up now. I guess fucking her changes one's perception.

I waited outside the exit from the flight gates. Person after person passed by as I eagerly hoped to get the slightest glimpse of the girls walking this way.

There they were! The girls were here!

I had an instant boner. It meant sex tonight. No Mr. Hand. It was warm flesh that would please my cock tonight.

I moved into the magazine shop, so they would pass by me. The girls were in matching light pink skirts and each carried a small duffel bag. We would head straight to the car. I pushed back against the wall as if it would hide me better.

As Kristy and Karly walked by they slowed down. I glanced at their cute asses. Soon I would be on my knees behind those pretty rumps and about to fuck my cock into a fine pussy. I stepped quietly forward as they looked around undoubtedly in search of me.

Karly was on the right. From behind, I quickly kissed her cheek. As she turned in reaction, I quickly moved to kiss Kristy's cheek. I missed. She had turned in response to her sister's reaction and all I got was air.

"Uncle Mike!" screamed Karly. I didn't remember her being so shrill before. She danced frantically up and down. In other circumstances, I would have assumed she needed directions to the bathroom.

"Uncle Mike!" shouted Kristy happily.

"Kristy! Karly!" I said and opened my arms.

They shot into my arms and we hugged. I was soon cognizant of their rubbing hands over my back. It possibly would not look okay to observers, so I reluctantly broke away. I'd fuck the girls right here if we wouldn't get thrown out. The girls wouldn't care. Airport security however probably frowned on an uncle fucking his two nieces in the middle of the walkway.

"Ready to go?" I asked.

"We need to get our bags," Karly said.

Kristy said, "You didn't really want us to come with only one set of clothes did you?"

Hell, yes I did! What were they thinking? This week was about fucking, fucking, and more fucking. Oh, the girls could go to the kitchen to get something to eat but it wasn't like you needed to wear clothes to do that. The best thing about two nieces was that while one niece rested the other niece was ready and fuckable. No breaks were ever needed!

"I meant are you ready to go get your bags," I said.

Kristy looked at me like she knew I lied.

"We'll need to take a break sometime," Kristy said. "We can go shopping for clothes. I bet you have really cool shops here."

Take a break? Couldn't she have just read my mind about taking breaks?

And shopping? For clothes? I didn't want my nieces wearing anything. I didn't want even a piece of sexy lingerie covering up any of their sexy bodies. Nakedness ruled!

Each girl had her own big bag and there was also a large duffel bag they shared. It was a heavy load to carry to my car. Make-up, hair dryers, brushes. It was so unnecessary. Fucking was an activity where the messier the better. Why brush cum out of your teeth when you'll have more in your mouth later? If it wasn't for their fucking hot fuckable cunts, sexy blonde hair, and toned teenage bodies, my nieces would likely drive me crazy. They were so immature mentally and emotionally, but oh how incredibly, incredibly mature they were sexually! Oh, yeah! Fucking their cunts was a trump card over any female deficiencies.

It was a forty-five minute drive to my house. I bought a little three bedroom house in the suburbs several years ago. The house wasn't much but I owned it.

On the travel home, everytime I passed a mall off the freeway the girls would perk up and actively look at all the signs. Pavlov's dog and bell chime had nothing on the response my nieces had to the sight of a mall. I did plan a couple of activities to 'cover' that Kristy and Karly did something with their Uncle Mike while they were out here. I certainly couldn't report back to Nick and Amanda that we rarely left my bedroom. I guess I could make the mall one of the activities.

"I need to go to the bathroom," said Karly about 35 minutes into the trip.

"Just a little longer," I said. She was fourteen and I had fucked her cunt many times but she could still whine like she was a little girl. Fine fuckable cunts over female deficiencies I reminded myself.

"The house is cute," said Kristy when I pulled into the driveway. The ability to park in my garage was a future project that I likely would never get around to doing.

The girls bustled into the house and explored. I was stuck bringing their bags inside which even included their two smaller bags.

"Why is the door at the end of the hallway locked?" Kristy said with a flirtatious grin.

Aw, that. The lock was something I added recently. I wanted the girls' first sight of my bedroom to be on my terms.

"You'll sleep here, Kristy," I said and pointed at the guest room with a twin bed.

I then pointed into my office door next to the guest room, "You'll sleep here, Karly. I'll get some blankets. Hopefully it's not too uncomfortable on the floor but you're young."

"What?" Karly cried out in shock.

Kristy quickly said, "He's joking but it's so not funny."

I smirked. I was rather pleased with my silly joke.

"That's not nice, Uncle Mike," chastised Karly.

"I'm sorry," I apologized with my grin still on my face.

"How could you believe that?" said Kristy and shook her head in wonderment.

"Ready to see my bedroom?" I said directly to Karly to ease her embarrassment. I took her hand and led her to the end of the hallway.

"Our bedroom," said Kristy.

"Right," I said and still grinned. I couldn't remember ever being happier.

I took my keys out of my pocket then inserted one key into the door.

"Tada," I said as I opened the door. Okay, it wasn't the most dramatic statement but I didn't plan that part of it very well.

The girls entered.

"Wow!" said Karly.

"This is weird," said Kristy.

"No, it's cool!" said Karly. "It's making my pussy wet."

That's my girl!

"This is freaky," Kristy said.

"You don't like it?" I asked.

"I don't know," said Kristy. She slowly spun around.

"I love it!" said Karly. "I can't wait to fuck in the middle of it." She plopped on the bed and propped her head up on a pillow.

All four walls of my bedroom were giant pictures of waterfalls. I wanted to recreate the feel and aura of fucking in the waterfall when we went camping.

"That's not all," I said excitedly. "Listen to this, Karly." I decided to focus on the niece who appreciated my efforts more.

I went over to my stereo and pressed 'play' on the CD player. Out of the four speakers in the corner of each room came the sounds of a waterfall. I turned up the volume so the sound effects filled the room, but not too loud that we couldn't still talk.

"Cool!" repeated Karly.

"This is so weird," repeated Kristy.

"When can we fuck?" said Karly. "This makes me even hornier than I was."

"It's hard to fuck when your clothes are still on," I teased.

"Come on, Kristy," Karly said. "Let's get undressed."

"What if I fuck you first?" I suggested. "Kristy is still getting used to the environment."

"Hey!" Kristy protested.

"You heard him!" said Karly. "He fucks me first!"

I didn't care who I fucked first. I just needed my cock inside one of my nieces' cunts.

I pulled off my shirt and Karly did the same with her shirt. I climbed on the bed and pulled at her skirt but the action dragged Karly. She laughed gleefully. Karly undid her clasp and lowered the zipper of the skirt. I tried again while she lifted her ass. Off went her skirt and I was onto her panties. Next I fumbled with her shoes as she took off her bra. The flurry of activity only took several seconds. When my task was completed, I sat up and worked on my own shoes then my pants. By the time I was only in my underwear, Karly was naked and up on her hands and knees. She faced the headboard and the large waterfall picture on that wall. My cock throbbed hard and repetitively which unexpectedly made it more difficult to remove my underwear.

I stared at Karly's little pink cunt lips. How long I waited to put my cock back in between them again! I rose up to my knees and scooted forward. I was so focused on my nakedness and Karly's cunt that I didn't notice Kristy was on the bed. Kristy, while still clothed, slid on her side before me. She grabbed my cock in her hand and put her mouth over it.

"Mmmm," Kristy moaned.

Karly looked back. "Hey! Uncle Mike is going to fuck me!"

"I'm just getting him nice and wet," Kristy said between delicious bobs on my cock. Oh, how delicious they felt!

"You don't have to. I'm so wet already," half-moaned, half-angrily said Karly. "I'm dripping."

Kristy bobbed a couple more times then said, "Go ahead. Fuck her good."

Kristy began to pull off her shirt but I was focused on Karly's sweet little 14-year old cunt. I closed the gap between my cock and her cunt, aimed the head into position, and thrusted forward.

"Oh, Uncle Mike!" Karly instantly moaned out as I entered her. Her knees buckled from ecstasy but she stayed up.

Fuck! Fuck! Fuck! I so missed my nieces! Her pussy was as wet as she advertised. It was warm and wonderful.

I said, "Your cunt is as good as I remember."

"Fuck me, Uncle Mike. Fuck me," purred Karly.

Fucking great idea!

I began to stroke inside her.

"Oh, yes! Yes!" cried out Karly.

"Fucking great cunt!" I growled and meant every word of it.

I gripped her thin waist and fucked her twat harder.

"Oh, fuck! Fuck!" shouted out Karly.

"Yes!" I grunted with every thrust and my power increased. "Yes! Yes! Yes!"

"Ohhhhhh, fuuuuuck!" Karly moaned out and her young lithe body trembled in my hands as she orgasmed.

I groaned deeply. I jabbed my cock as far inside as possible. My cock ached for release. The pressure was almost too intense. I gasped out and felt great satisfaction as I spewed spray after spray of my cock's cummy contents into Karly's cunt.

"Oooooh," she moaned as her pussy was reminded of the feel of my jizz.

"Oh, fuck!" I groaned and collapsed down onto my knees. It was so tremendous.

My thoughts immediately turned to Kristy so my cock stayed semi-hard. As soon as Karly rolled onto her back in post-orgasmic bliss, Kristy retook my cock into her mouth. Within the minute, I was hard and ready.

I caressed Kristy's cheek where my cock bulged in it. She looked up and I nodded. She scrambled to her hands and knees where Karly was a moment ago. I looked eagerly at her more mature but still very youthful 17-year old cunt. The way my cock waved in front of her cunt gave the impression it looked over Kristy with its one 'eye'.

I pushed forward.

"Ohhhh!" Kristy immediately moaned. "I so love your cock!"

I could understand her sentiment. I so loved my cock when it was in her cunt.

"Fuck! Fuck!" I grunted as I wasted no time and pounded into her.

"Yes! Oh, yes! Oh, fuck! Fuck!" Kristy responded.

Oh, fuck, it was good to be with my nieces again. Did I mention that before? I might say it again. It was so good to fuck Kristy and Karly again!

"Oh, Uncle Mike," Kristy moaned. "You stretch my cunt so good!"

"Fuck!" I grunted as I continued my twat slam.

"Yes! Yes! Yes!" Kristy said louder.

"Oh, fuck!" I groaned. Was I that close to cumming already?

"Yessssss," Kristy verbally stretched out and I could tell she was on the peak of orgasm.

I decided to change rhythm. I switched to slow long strokes.

"Fuuuuuck!" moaned Kristy. "Oh, yes!"

Kristy's orgasm started.

"Oh, Kristy," I groaned as her cunt contractions moved my cock to the bursting point.

I hissed out and bathed her cunt in healthy doses of my cum.

"Ooooooh, yes, Uncle Mike. I feel it."

My cock slowly exited Kristy's cunt. It was limp this time but I didn't care. I was very happy. Okay, here it is again - I was very happy to be with my nieces again.

We dozed that afternoon. I was on my back and each niece lay against my side with my arm around her with my hand on her bare ass. What a peaceful and blissful way to sleep!

I woke up an hour later with the need to pee. When I returned Kristy was awake. I motioned for her to lie on her back. She opened her legs and I reentered her. We fucked while Karly slept by our side. By the time I came inside Kristy, sister Karly was awake. I rolled to my back, Karly sucked me to hardness, then mounted my cock. She bounced on top of me until we both came powerfully again.

I took the girls out to dinner. I didn't want to take the chance that the girls would get sick by cooking for them. I wanted them healthy all week long. Oh, I could handle breakfast and lunch, but anything fancy ... okay, maybe "fancy" was not the right word. The better word was probably "complicated". The key emphasis was that I didn't want any of the girls to be out of commission because of something they ate. I had my priorities.

I fucked Kristy's cunt and Karly's cunt before we went to sleep that night. Imagine that, heh-heh!

"Put these in your bags," I said after morning breakfast which was after I fucked Kristy then Karly. We were in my bedroom. I know, I know, it's no surprise.

Fucking - it does a body good! Fucking was an essential part of any healthy life! Fucking your two nieces gets your day off right!

Advertising executives had nothing on me.

"What are they?" asked Kristy as each girl took one.

"Museum stubs," I answered.

"What's a museum stub?" Karly inquired.

I said, "It's like a movie theater stub. You take your ticket to the guy standing in front and he rips your ticket in two and gives you half. That's a stub."

Kristy's face was a knowing smile. Karly's face was a question mark.

"I don't understand," Karly said.

"Do you want to go to the museum?" Kristy asked.

"Not really," Karly answered hesitantly as if she didn't want to disappoint me.

"Neither do I," I answered with a grin. Karly looked further confused.

"You can be so dumb," said Kristy.

I shot a sharp glance at Kristy to say "take it easy on your sister".

Kristy said, "We're not going to the museum. Uncle Mike bought tickets to show that we went to the museum."

"Why... ?" Karly said.

Kristy shook her head in annoyance. "The main reason we're here is to fuck Uncle Mike."

"I know," said Karly with a voice that showed she was bothered by Kristy's condescension.

I decided to step in. "We need to prove we went and did things while you visited. This will look like we went to the museum when all we did was this..."
