We settled into the sleeping bags, both of us on our breadbasket, I had a book I was going to translate but she just laid her head on the pillow watching me. I rolled to my backrest and held the book so the pages would catch the watery light from the barrage fire lamp. My babe Helen flipped to her side away from me as if to kip. We were on a house camping slip ; mom, dad, me and my sis and our golden lab nut case, AKA ‘ Screw ’. At that moment screwing was lying on my feet at the bottom of my bag. I tried to plain him off to make a motion to Helen's bed but he wouldn't Don Budge, my infantry were pinned to the ground by the 70-pound dog. I was 18 at the fourth dimension and my sister was quickly approaching 16 but since we only had two tents, I was forced to take Helen into one with me, our parents required their privacy. This had been the sleeping transcription for years and they gave no thought to the fact I was pretty much an adult. I was going to ingest to expend four nights with my baby sister in the Sami blank space, I would have to be damn careful if I jacked off.

We were in the lot of Western Oregon. We planned on hiking some of the many mountain trail, kayaking and sportfishing on the Umpqua River. Our stay would be four daytime and Nox. Dad had his camera with three various sized lenses hanging from lanyards around his neck opening, he looked like a Nipponese tourist. I wore a heavy shtup haversack with power snacks and deglutition while mom and Helen of Troy got to enjoy the day unencumbered by anything but Screw's lawn tennis chunk which they threw as we hiked. After setting up bivouac and settling in the first night, we could centralise on the Clarence Day coming. That was the Night Screw told me ‘ screw you, this is my bed ’.

The next day, the first full day, was spent hiking, we might own covered 15 miles of hills and vale following a twosome of the popular trail and met respective other hiking radical along the way. By the time we returned to the clique my legs were straining, I was tired from want of sleep, I was ready for some down time. It wasn't full wickedness when we got back to the campsite where mom and Helen cooked a campfire dinner then dad retrieved some beer from a cooler in the rear of the truck. Neither my sister nor I refused when he offered us a bottle, Mom tried to object"Goddamn it Roy, they aren't old enough."

"Ah piss Margie, it's been a long hot day, we could all use one."I wasn't a stranger to beer but I wasn't sure if my sister had tasted any before. When she tipped the nursing bottle and sucked down two quick sup, I knew, she wasn't virgin to beer either. The Milky Way was brilliant in the night sky when we went to the tents. I had to stay out until my sister changed into her slumber wear then she invited me in. I wasn't so damn low so I stripped to T and shorts then slipped my PJ pants on while my babe tried not to watch. She didn't try very hard, she kept glancing at me as I changed. jailer immediately took his spot in the eye of my bag and refused to displace. As Helen of Troy laughed at my efforts to move Screw, the fucking dog groaned contentedly and rolled to his vertebral column. He wasn't about to give up his space easily. I laid on the bag and tried to take out it over me but got only one-half covered, my ass was sticking out in the night air which was getting colder. I flopped and flipped and tugged but couldn't get any more cover than what Screw allowed. My sister was lying comfortably on her stomach watching me with undisguised amusement while I got frustrated with the sleeping arranging.

I gave up trying to get completely covered and lay silence with my pass on English getting cold, my toes were numb. Helen had gone to log Z's, she looked so peaceable, so warm. Our suitcase were not mountain climbing bags ; narrow, down stuffed coffin, but larger ; large enough for two if the two didn't take care some torso contact during the night. roll in the hay it, I was cold, the dog owned my bed so I crawled across the small distance between the bags then lifted the top of Helen of Troy's and carefully put beside her. She rolled to her position away from me so I had room to lie on my side behind her and pull in the cover over, we were back to punt. Ah, that felt good, I was super tired and the warmth of the bed lured me into a immobile, late slumber.

Hands pushing on my back woke me up. I opened my heart and looked out the minuscule net window over my mind, it was not full day, but quickly break of the day. The hands on my back pushed again, with more importunity, I rolled over to face up Helen."What the hell are you doing in my bed ?"was the first thing she said.

"I was cold."

"You were cold so you think that's a good reason to log Z's with me ! ?"

"Shh, you'll viewing mom and dad."

She toned down the mass"Get out, god, I have to go pee and you're in the way."Screw came alert, rose from his ( my ) sleeping bag and stuck his big olfactory organ in my boldness, he was cook for the day too. shite. I threw back the top screening and stood, Helen quickly followed then slipped out to go pee somewhere while I changed back into my clothes. shag followed my Sister.

The day passed with more hiking and a little, fun, run over some stratum II rapids in our inflatable kayaks. That evening after dinner and another stale beer my sister and I returned to the tent. piece of ass didn't hesitate to stake his title to my bag, directly in the middle. Some fucking eldritch law of physics about dogs lets them gain weight when they lie down. The normally 70-pound Lab weighed about 150 pound when I tried to move him. After a little scuffle I gave up and told Helen"I'm with you again."

She looked at the dog then at me with divert eyes,"I don't think you have a choice, turn your spinal column while I change."

She was behind me, asleep I think, but I wasn't. The tactile property of a girl's ass pressed against my book binding was really starting to stir my Lucille Ball. My cock elevated to ‘ proud'and my junkie were tingling. I tried my best to cut the cause of my growing arousal but my sister was too nigh. Lying with her was causing a tempest of immoral sentiment and delightfully awful musical theme as my clump began to languish. I was beginning to overheat. I kicked the cover off my legs to cool off off and just as I did Helen rolled completely to her early slope and threw an arm over my waist. She was lying against me, her tits pressed on my backbone, her inguen fitted against the curve ball of my ass. I damn near climaxed when the finger on her hand flexed against my abdomen and the soft ardent breath from her nostrils wafted on my neck."Are you awake ?"I whispered. No answer, and the deep even breath on my pelt let me hump she was still benumbed.

I reached over my back and put a hand on her hip then gently pulled her even tighter against me, I could sense her pubis detrition on my butt. My cock thumped and spit a guggle of pre-cum into my underdrawers. Helen murmured something then bent her back, moving her pussy away from me. When she did her chief pressed against my ear, her knees touched the back of mine. I could feel the top of her tits heating my shoulder blade.

I lay still but my heart was thundering, my heated up blood line was warming the full tent. Helen of Troy hadn't moved for a few transactions then she shifted slightly away and went to her binding. I took advantage of the move and rolled to face her. Her centre were closed, her dresser ascension and falling evenly, she was still out. Driven by the hormones flowing full flood in my mineral vein, I put a hand on my sister's leg just over the articulatio genus. She didn't object so within arcsecond I eased it up until the boundary of my hand pressed her body at the junction of her legs. Helen of Troy rolled her pass to the right, away from me, then her legs moved boost apart. Encouraged by her move I put my hand over her pussy, the cloth of the pajama pants was quick and damp, and getting warmer. I don't know if it was because of the heat I was radiating or it was her, but the temperature in the sleeping bag rose another 20 degrees. I rubbed my sis's sex lightly which caused her hips to shiver. When she reacted to my skin senses like that I was lost, I was going to fuck her even as she slept.

I carefully moved my mitt to her stomach, over the band of her drawers then eased my finger under the elastic. I pushed my hand into her panty then down and through her soft pubic hair until I was again covering her slit, only there was no material between her and my fingers. I flexed my long finger then stroked Helen from ass to clit. She gasped lightly, rolled her hips then let her breath out of partially open up lips, my erecting damn near split open with the heat energy and pressure. Slowly I moved my fingertip in band as I pressed between the lips of her snatch until I felt the opening of her body, she was affectionate and wet, I easily slid my finger into her to the second knuckle. I began to finger fuck my lilliputian sister and her branch moved even further apart.

I stroked Helen and she was warming, her slit was getting wetter and hotter, the puffy pillows of her cunt were growing softer. My Sister humped her hips, moaned, then put a hand over mine and pressed it closer to her body. She rolled her head to me and one-half way opened her oculus, her lips parted slightly as she puffed inadequate sips of air. I pressed my aching hard-on against her leg and humped it like I was fucking her. Helen of Troy's eyes flew panoptic with surprise and her rim formed the silent word"NO !"She gripped the hand between her leg and jerked it out of her trouser then rolled away far enough that there was no more touch between us. Rebuked by Helen for making a strait at her, I rolled away then dig my overheated rooster into the cool nighttime air. I gave her decent meter and blank to go back to sleep before I dared rap it. Even with the insistency off I worried like netherworld she would severalise our parents what I did. lie with never opened an eye.

The future morning my sister didn't lead off a war or say anything to me or dad about me molesting her while she slept. After couple of minute in her company, I my frayed mettle calmed and I became comfortable around her again. The day passed, I spent much of the time catching and releasing several vauntingly trout. Helen and Screw roamed the nearby hills and John Rock, mom and dad went for a cost increase. It was a hot mid-afternoon when Helen and the dog came back to where I was fishing. The big yellow lab didn't ask license or hesitate to jump off into the river pool I was fishing in as my Sister complained"I'm hot, I wish I brought my swim suit."

"You can go wading, that should chill you off, at least your legs."

Helen thought a moment then said"I want to get all wet. I'll wear my bra and panties but you can't stare or make fun of me."

"I won't, in fact, I'll get in the weewee too, in my Jockey shorts if that's okay."She didn't result but started unlacing her hiking boots. As my sis undressed to underwear, I did the same.

Even though I'd been in bed with my sister twice and damn near raped her the night before I'd never seen her without clothes before. Being in the final phases of pubescence, her physical structure was a vista of soft curve ball, firm fleshy pitcher of tits and ass, she glowed with animation. She had morphed from a precious little girl to a pretty teen and at eighteen year old, pretty stripling young woman attracted me like fucking attraction. Helen was no different. I watched as she stepped into the body of water wearing just brief scanty and a delicate full-of-the-moon bra, and my nuts vibrated. She turned to me and asked"Are you coming ?"

"Not yet but damn near."

"Huh ?"

"Yeah, I coming"I said as I pulled off my shirt.

We splashed and played in the refreshing H2O, throwing the nut for Screwball, laughing and bantering, just having a fun sibling episode. Neither of us was self-conscience about frolicking in our underwear, it became a dead letter as soon as we were in the weewee. After a half hour or so Helen of Troy got out of the river then went into our tent, moments later she stepped out to hang her delicate wear on a Sir Herbert Beerbohm Tree leg. She was naked. I stopped moving and stared at my sis, she turned and saw me looking at her, flushed pink in the cheeks then scuttled quickly back into the collapsible shelter. My prick flared with carnal interestingness. The dog leaped at the ball, reminding me he was still there.

That was the hold up full day at the cantonment, we would be leaving in the morning. After dinner party mom and dad shared the last of the beer with us while they showed us scores of video taken on the hikes. A little before ten that evening, they bid us practiced dark and went to lie. Helen and I were left to stare at the star. We ignored each early while we tried to get signals on our smartphones but it was a wasted effort. In three days, we hadn't been able to connect with friends or Facebook. My sister gave up and said sound night then retreated from the moonshine to the tent. Me and ass stayed international, giving her time to get settled in bed. It was well into the late hours when I finally went to join Helen. Screw took up his locating in the heart of his sleeping bag and challenged me with his eyes to push him away. I didn't even try. I changed to my nap wear then went to bed with my babe. I turned off the bombardment lamp before I crawled into the bag future to her so I didn't see Helen as I lay behind her. When I was on my spinal column in the bag she shifted slightly, bent her leg at the human knee which put her understructure on my lower leg. Her toes twitched against my ankle which caused a thrill to shiver up my leg. Helen turned over to front me, looped an arm over my chest and snuggled to my incline. Her breasts were pressed on my shoulder, her legs rubbing mine. My putz exploded in length and cinch, I started to panic because if she didn't move, I would start something she might not care again. I reached across my physical structure to push her away and when my hand touched her, it was strip peel I felt. My header jerked back, I squinted in the iniquity at her then moved my bridge player from her shoulder down her English. She wasn't wearing anything. Helen was naked under the cover. My heart started tripping, my face flushed hot, my turncock bobbed with each accelerate heartbeat. Just as my hand slid over her leg, she turned her font up then nuzzled my cervix. Her handwriting moved from my bureau, down my stomach, under the isthmus of my pj's then her finger's breadth encircled my hard-on. She started rocking her hip, rubbing her mole on my thigh as she managed to campaign my sleep pants down, off my waist.

I rolled to my side to face my baby and she pulled me closer by my hard-on until it touched the junction of her stage. The end of it slipped between the hot wet bend of her sex then I felt the head word enter her. Helen held it tighter then started rolling her back, pumping her body on the difficult muscle between her legs. She gasped softly, moved her hand and put it on my hip. She pulled me even closer which forced my cock deeper into her. I pushed against her making her go to her back while pinned to me by my cock. When I was over her, she spread her legs as far apart as she could in the quiescence bag then put her sleeve around my backrest and pulled me down. I was lying on her from breakwater to breasts, she puffed softly in my ear then began to make a motion with me. lupus erythematosus than a minute after going to bed with Helen, we were fucking.

What we were doing was not only a phantasy come true, but also a surprisal. Helen of Troy had stripped nude then waited in the collapsible shelter until I came to her. She knew that Screw would highjack my bed and I would be forced to share her bag with her again. My sister got hot for me, waited, then without saying a Holy Writ, invited me to have sex with her. I pushed up on my blazonry, looked down on the middling fifteen-year-old girl and smiled my delectation as I plunged down and in. My soundbox slapped hers too loud so she put a bridge player between us to break what I was doing. We had to be quiet, the material rampart of the tent were not soundproof, something we learned long before. Helen of Troy put a finger to her backtalk to schuss me then smiled, humped her back and I started fucking her again, only softy, quietly.

She was warm, piano, legal tender and deep. We were both heating up more as my cock slid in and out of her easily. I pushed into her as far as I could and held still as I twitched my stopcock, causing her to heave and groan softly. The unruffled outburst wasn't quiet enough because just after Helen of Troy grunted, we heard our mother claim out from the early tent"Helen, are you okay, what's amiss ?"

We froze, afraid to move, my erection was lodged in her, her legs crossed over mine. Helen took a breathing space then answered"That goddamn dog is lying on my legs, I'm trying to quetch him back to James Mason on the other sleeping bag."With that one statement Helen said two thing, she covered for the noises and hinted I was in my own bag.

Just as our mom said"OK, good night dear"I pulled out of her pie-eyed pussy and erupted. I gushed cum into the cracking of my sister's ass, down her butt to the bag. When I was done convulsing, I lifted off her and went back to my side.

Helen was grinning, her eyes sparkled in the nighttime, she whispered"You messed up my bed."

"bettor than in you."

She put a hand on my face and pulled my face close enough she could suspire in my ear"Yeah, maybe, but I'm not done, I hope you can get it up again."Saviour, this was a babe I didn't know, but sure as hell was one I was volition to see about.

I didn't answer verbally, I reached between her legs then started rubbing her button with two fingertips. Her hot clit swelled immediately, she widened the gap between her second joint and began to sleep together her back. I could feel her getting prepare to climax but didn't want her to start yelping so I felt around in the dark until I found a sock. I put it to her lips, she opened her mouth and I stuffed it in. mo later Helen was staring at me with wide, passionate centre and a sock jammed between her teeth when she launched into the clouds on a trip of raptus. The rush of air through her nostril was the just noise she made.

We couldn't talk ; I couldn't ask her why she came on to me and let me screw her but I sure as perdition wasn't going to complain. As her chest rose and fell while she relaxed on the downside of her sexual climax, I put a paw over the firm mound of her give breast. Helen pushed the wind sleeve out of her sass with her clapper then put a hand over mine and pressed it to her chest, she put her eyes on mine then smiled. I tweaked the mammilla which caused her hat to flutter. I played with my sister's tits while she slipped a bridge player over my prick and began to promote another session. She and I played, felt and got hotter until my erecting was what we both wanted it to be. I pushed her so she was facing away from me then she lifted her top leg, reached between hers and grabbed my erection. Helen pumped it three or four prison term then rubbed the point against her slit. She loosened her bobby pin then with just her fingertips put it where she wanted it. I slipped into my babe's bid wet tunnel and began to fuck her again, totally silent, totally lost in her hot velvet twat.

Maybe eight or nine proceedings after I started fucking her, Helen started flopping a hand around, looking for something in the iniquity. I paused and pulled out then whispered in her ear,"What ?"

I barely heard the resolution"The sock, where is it ?"It was lying next to my straits so I took it and handed it to Helen. She jammed the drogue in her mouth again then arched her back, pressing her ass against my groin. I slid my erection back into her then heard the muted sigh as she took every inch I could give her.

My muscle were tensing, my tool was bloated with cum, I was ready to erupt. Helen's eubstance was flowing in moving ridge against me, her kitty-cat flooded with wet rut. When I pulled out of her she pushed back on me, trying to keep me captive in her trunk. She felt me pulling back but put a hand on my hips and pulled me miserly against her. She didn't want me to deplume out so I breathed a monition close to her ear"I'm gon na cum."She didn't say anything, she couldn't with the sock in her rima oris, but the bridge player on my ass gripped even harder. The military capability of her grip as she held me let me have a go at it I didn't have to pull out. My erection clenched then I started cumming in my sis. She must have been teetering on the edge too because when I slammed closely against her she groaned and started vibrating from legs to head. My Sister came in sync with the erecting pulsing in her.

Just as she stopped shaking, we heard"Helen ?"

Helen jerked the sock out of her lip and answered as calmly as she could"That fucking dog won't motion dad."

We heard a easygoing chortle"That's no reason to swan like that. Try to get some sleep."My relaxed prick slipped out of my sister's muddle, followed by a laundry of semen. My babe turned over, put an arm over my chest and hugged me while her breathing slowed to convention.

I fucked Helen twice more that Nox and we managed to keep from alerting our parents to what we were doing. The dog slept carefree on my dormancy bag, my baby and I didn't get any sleep at all. Days later I overheard our father talking to our female parent,"When we go camping with the kids again, we should get hold of another tent or eternal rest men in one, char in the other."

"Why ?"she asked.

"Because I found a vauntingly stigma in the bag Mason slept in, he either had a wet dream or masturbated. That's normal for an 18-year-old, but we should continue a distance between him and Helen from now on, she doesn't need to be exposed to his night activities."

I smirked, because he was one camping trip too late .
