We settled into the sleeping suitcase, both of us on our stomachs, I had a leger I was going to say but she just laid her head on the pillow watching me. I rolled to my back and held the book so the pages would catch the decrepit visible radiation from the battery lamp. My sister Helen flipped to her side away from me as if to log Z's. We were on a fellowship camping trip ; mom, dad, me and my sis and our golden lab Screwball, AKA ‘ Screw ’. At that moment nookie was lying on my feet at the bottom of the inning of my bag. I tried to kick him off to motivate to Helen's bed but he wouldn't Budge, my human foot were pinned to the ground by the 70-pound dog. I was 18 at the time and my sister was quickly approaching 16 but since we only had two tent, I was forced to take Helen into one with me, our parents required their privacy. This had been the sleeping arrangements for years and they gave no persuasion to the fact I was pretty very much an adult. I was going to have to spend four Nox with my sister sister in the same infinite, I would have to be damn careful if I jacked off.

We were in the mountains of Western Oregon. We planned on hiking some of the many mountain trails, kayaking and fishing on the Umpqua River. Our stay would be four days and nights. Dad had his camera with three various sized lens system hanging from lanyards around his neck, he looked like a Nipponese tourer. I wore a weighed down fucking haversack with power snacks and swallow while mom and Helen got to delight the day unencumbered by anything but Screw's lawn tennis lump which they threw as we hiked. After setting up encampment and settling in the foremost Night, we could condense on the days coming. That was the dark ass told me ‘ screw you, this is my bed ’.

The next day, the first full day, was spent hiking, we might consume covered 15 miles of Benny Hill and vale following a couple of the popular trails and met various former hiking grouping along the way. By the time we returned to the camp my wooden leg were straining, I was tired from lack of sleep, I was ready for some down meter. It wasn't full wickedness when we got back to the bivouac where mom and Helen cooked a campfire dinner then dad retrieved some beer from a cooler in the back of the truck. Neither my babe nor I refused when he offered us a bottleful, Mom tried to object"Goddamn it Roy, they aren't old enough."

"Ah piss Margie, it's been a longsighted 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 bottleful and sucked down two ready drink, I knew, she wasn't Virgo the Virgin to beer either. The Milky Way was brilliant in the Nox sky when we went to the tent. I had to stay out until my sister changed into her rest wearing then she invited me in. I wasn't so damn modest so I stripped to T and trunks then slipped my PJ pants on while my sister tried not to watch. She didn't try very hard, she kept glancing at me as I changed. Screw immediately took his berth in the eye of my bag and refused to incite. As Helen laughed at my efforts to impress screw, the roll in the hay dog groaned contentedly and rolled to his back. He wasn't about to establish up his outer space easily. I laid on the bag and tried to pull 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 covering than what screw allowed. My sis was lying comfortably on her abdomen watching me with undisguised amusement while I got frustrated with the sleeping arrangements.

I gave up trying to get completely covered and lay tranquil with my go forth incline getting low temperature, my toes were numb. Helen of Troy had gone to sleep, she looked so peaceful, so warm up. Our old bag were not mountain climbing bags ; narrow, down stuffed coffins, but big ; great enough for two if the two didn't take care some consistency contact during the night. Fuck it, I was cold, the dog owned my bed so I crawled across the small space between the suitcase then lifted the top of Helen's and carefully laid beside her. She rolled to her English away from me so I had room to lie on my side of meat behind her and pull the cover over, we were back to stake. Ah, that felt good, I was super bore and the heat of the bed lured me into a immobile, deep nap.

deal pushing on my back woke me up. I opened my middle and looked out the small-scale net window over my head, it was not full daylight, but quickly dayspring. The hands on my back pushed again, with more urging, I rolled over to front Helen."What the infernal region are you doing in my bed ?"was the first thing she said.

"I was cold."

"You were cold so you think that's a just reasonableness to sleep with me ! ?"

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

She toned down the volume"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 nose in my face, he was ready for the day too. poop. I threw back the top natural covering and stood, Helen quickly followed then slipped out to go pee somewhere while I changed back into my clothes. Screw followed my sister.

The day passed with more tramp and a short, fun, run over some Class II rapids in our inflatable kayaks. That evening after dinner and another coldness beer my baby and I returned to the tent. screw propeller didn't hesitate to post his claim to my bag, directly in the middle. Some fucking unearthly law of physics about dogs LET them gain weighting when they lie down. The normally 70-pound Lab weighed about 150 pounds when I tried to move him. After a short rough-and-tumble I gave up and told Helen of Troy"I'm with you again."

She looked at the dog then at me with disport centre,"I don't think you have a choice, grow your book binding while I change."

She was behind me, asleep I think, but I wasn't. The feeling of a little girl's ass pressed against my back was really starting to stir my balls. My dick elevated to ‘ majestic'and my nuts were tingling. I tried my estimable to ignore the grounds of my growing stimulation but my sister was too near. Lying with her was causing a tempest of base thoughts and delightfully foul ideas as my balls began to suffer. I was beginning to overheat. I kicked the binding off my legs to cool off and just as I did Helen of Troy rolled completely to her other side and threw an arm over my waist. She was lying against me, her tits pressed on my back, her bulwark fitted against the curve of my ass. I damn near climaxed when the finger's breadth on her hand flexed against my stomach and the soft strong breathing time from her nostrils wafted on my neck."Are you awake ?"I whispered. No result, and the mystifying even breathing place on my skin let me cognize she was still asleep.

I reached over my back and put a hand on her hip then gently pulled her even tighter against me, I could feel her pubis rubbing on my butt. My peter thumped and spit a bubble of pre-cum into my underdrawers. Helen murmured something then bent her back, moving her twat away from me. When she did her question pressed against my ear, her knees touched the back of mine. I could finger the crown of her mamilla heating my shoulder blade.

I lay still but my ticker was thundering, my heated line of descent was warming the total collapsible shelter. Helen hadn't moved for a few minutes then she shifted slightly away and went to her rear. I took vantage of the move and rolled to front her. Her middle were conclude, her chest insurrection and falling evenly, she was still out. Driven by the internal secretion flowing good flood in my veins, I put a mitt on my sister's leg just over the genu. She didn't object so within indorsement I eased it up until the boundary of my handwriting pressed her soundbox at the junction of her ramification. Helen of Troy rolled her head to the right, away from me, then her ramification moved further apart. Encouraged by her move I put my hand over her pussy, the cloth of the pajama bloomers was warm and damp, and getting heater. I don't know if it was because of the high temperature I was radiating or it was her, but the temperature in the sleeping bag rose another 20 point. I rubbed my sister's sex lightly which caused her rose hip to shiver. When she reacted to my touch like that I was lost, I was going to fuck her even as she slept.

I carefully moved my hand to her stomach, over the dance orchestra of her pants then eased my fingers under the elastic. I pushed my hand into her panty then down and through her cushy pubic whisker until I was again covering her scratch, 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 rose hip then let her breath out of partially open air backtalk, my erection shit near schism open with the high temperature and pressure. Slowly I moved my fingertip in circles as I pressed between the lips of her twat until I felt the first step of her body, she was warm and wet, I easily slid my finger's breadth into her to the secondment knuckle. I began to feel fuck my small Sister and her legs moved even further apart.

I stroked Helen and she was warming, her incision was getting wetter and hotter, the puffy pillows of her pussy 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 straits to me and half way opened her eyes, her lips parted slightly as she puffed brusk sips of air. I pressed my aching erection against her leg and humped it like I was fucking her. Helen's eyes flew wide with surprise and her rim formed the dumb word"NO !"She gripped the hired hand between her legs and jerked it out of her bloomers then rolled away far enough that there was no more contact lens between us. Rebuked by Helen for making a fling at her, I rolled away then poked my overheat hammer into the cool nighttime air. I gave her enough time and distance to go back to sleep before I dared whang it. Even with the pressure off I worried like hell she would tell our parents what I did. Screw never opened an eye.

The adjacent morning my baby didn't start a war or say anything to me or dad about me molesting her while she slept. After couple of hours in her caller, I my frayed nerves calmed and I became comfortable around her again. The day passed, I spent much of the time catching and releasing several large trout. Helen and Screw roamed the nearby hills and rock and roll, mom and dad went for a hike. It was a hot mid-afternoon when Helen of Troy and the dog came back to where I was fishing. The big yellowness lab didn't ask license or hesitate to jump off into the river syndicate I was fishing in as my sis complained"I'm hot, I wish I brought my swim suit."

"You can go wading, that should cool you off, at to the lowest degree your legs."

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

"I won't, in fact, I'll get in the water too, in my legal brief if that's okay."She didn't answer but started unlacing her hiking boots. As my sister undressed to underwear, I did the same.

eventide though I'd been in bed with my sister twice and beshrew near raped her the night before I'd never seen her without apparel before. Being in the final stage of pubescence, her torso was a vista of soft curves, firm fleshy heap of titty and ass, she glowed with energy. She had morphed from a cunning little girl to a pretty teen and at xviii age old, pretty stripling missy attracted me like fucking magnets. Helen was no different. I watched as she stepped into the body of water wearing just brief panties and a soft full bra, and my egg 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 weewee, throwing the ball for nut case, laughing and bantering, just having a fun sibling episode. Neither of us was self-conscience about frolicking in our underclothing, it became a non-issue as soon as we were in the water. After a half 60 minutes or so Helen of Troy got out of the river then went into our collapsible shelter, moments later she stepped out to cling her finespun clothing on a tree offshoot. She was nude statue. I stopped moving and stared at my sister, she turned and saw me looking at her, flushed pink in the cheeks then scuttled quickly back into the tent. My putz flared with carnal interestingness. The dog leaped at the ball, reminding me he was still there.

That was the last full day at the camp, we would be leaving in the dayspring. After dinner mom and dad shared the last of the beer with us while they showed us slews of pictures taken on the boost. A little before ten that evening, they bid us just night and went to pillow. Helen and I were left to stare at the star topology. We ignored each former 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 protagonist or Facebook. My babe gave up and said good night then retreated from the moonshine to the tent. Me and gaoler stayed out of doors, giving her time to get settled in bed. It was well into the former hours when I finally went to join Helen. turnkey took up his view in the middle of his sleeping bag and challenged me with his eyes to push him away. I didn't even try. I changed to my log Z's wear then went to bed with my sister. I turned off the shelling lamp before I crawled into the bag future to her so I didn't see Helen of Troy as I lay behind her. When I was on my book binding in the bag she shifted slightly, bent her leg at the knee which put her metrical foot on my humbled leg. Her toes twitched against my ankle which caused a bang to shiver up my leg. Helen of Troy turned over to present me, looped an arm over my dresser and snuggled to my side. Her breasts were pressed on my shoulder, her legs rubbing mine. My stopcock exploded in distance and girth, I started to panic because if she didn't move, I would go something she might not like again. I reached across my consistency to agitate her away and when my bridge player touched her, it was bare skin I felt. My head jerked back, I squinted in the nighttime at her then moved my script from her articulatio humeri down her side. She wasn't wearing anything. Helen of Troy was naked under the mantle. My heart started tripping, my font flushed hot, my cock bobbed with each speed up heartbeat. Just as my mitt slid over her leg, she turned her face up then nuzzled my neck. Her hired man moved from my chest, down my breadbasket, under the band of my pj's then her finger's breadth encircled my erection. She started rocking her hip, rubbing her groin on my thigh as she managed to labor my sleep trouser down, off my waistline.

I rolled to my incline to present my Sister and she pulled me nearer by my erection until it touched the joint of her legs. The end of it slipped between the hot wet folds of her sex then I felt the top dog enter her. Helen held it fuddled then started rolling her back, pumping her body on the grueling muscleman between her legs. She gasped softly, moved her hand and put it on my hip. She pulled me even closer which forced my pecker 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 peg as far apart as she could in the sleeping bag then put her arms around my back and pulled me down. I was lying on her from mole to knocker, she puffed softly in my ear then began to move with me. to a lesser extent than a minute after going to bed with Helen, we were fucking.

What we were doing was not only a fantasy come true, but also a surprise. Helen had stripped nude then waited in the collapsible shelter until I came to her. She knew that Screw would commandeer 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 word, invited me to consume sex with her. I pushed up on my implements of war, looked down on the jolly fifteen-year-old daughter and smiled my enjoyment as I plunged down and in. My torso slapped hers too loud so she put a hand between us to finish what I was doing. We had to be quiet, the cloth walls of the collapsible shelter were not soundproof, something we learned long before. Helen put a finger to her lips to schuss me then smiled, humped her back and I started fucking her again, only softy, quietly.

She was ardent, sonant, stamp and mystifying. 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 carry still as I twitched my cock, causing her to gasp and groan softly. The quiet down effusion wasn't quiet enough because just after Helen grunted, we heard our female parent birdcall out from the former tent"Helen, are you okay, what's wrongfulness ?"

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

Just as our mom said"okeh, well night dear"I pulled out of her plastered pussy and erupted. I gushed cum into the crack of my baby's ass, down her butt to the bag. When I was done convulsing, I lifted off her and went back to my position.

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

"bettor than in you."

She put a mitt on my cheek and pulled my face close enough she could respire in my ear"Yeah, maybe, but I'm not done, I hope you can get it up again."Jesus, this was a sister I didn't know, but sure as snake pit was one I was leave to learn about.

I didn't answer verbally, I reached between her legs then started rubbing her clit with two fingertips. Her hot button swelled immediately, she widened the gap between her thighs and began to hump her back. I could feel her getting fix to climax but didn't want her to start yelping so I felt around in the iniquity until I found a sock. I put it to her lips, she opened her mouth and I stuffed it in. moment later Helen of Troy was staring at me with wide, passionate eyes and a sock jammed between her teeth when she launched into the swarm on a head trip of ecstasy. The rush of air through her nostrils was the only noise she made.

We couldn't talk ; I couldn't ask her why she came on to me and let me have sex her but I sure as hell wasn't going to complain. As her bureau rose and fell while she relaxed on the downside of her orgasm, I put a hand over the firm pitcher of her left breast. Helen pushed the air sock out of her mouth with her tongue then put a hand over mine and pressed it to her tit, she put her heart on mine then smiled. I tweaked the nipple which caused her chapeau to flutter. I played with my sister's pap while she slipped a hand over my dent and began to further another session. She and I played, felt and got hotter until my erection 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 of Troy pumped it three or four clip then rubbed the head against her snatch. She loosened her grip then with just her fingertips put it where she wanted it. I slipped into my babe's legal tender wet tunnel and began to do it her again, totally silent, totally lost in her hot velvet puss.

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

I barely heard the answer"The sock, where is it ?"It was lying next to my head so I took it and handed it to Helen of Troy. She jammed the sock in her backtalk again then arched her back, pressing her ass against my groin. I slid my erecting back into her then get word the strangle suspiration as she took every inch I could move over her.

My muscleman were tensing, my stopcock was bloated with semen, I was ready to erupt. Helen's body was flowing in waves against me, her pussy flooded with wet high temperature. When I pulled out of her she pushed back on me, trying to observe me imprisoned in her body. She felt me pulling back but put a manus on my hips and pulled me tight against her. She didn't want me to pluck out so I breathed a warning close to her ear"I'm gon na cum."She didn't say anything, she couldn't with the windsock in her mouth, but the hand on my ass gripped even harder. The strength of her grip as she held me let me know I didn't have to pull out. My erection clenched then I started cumming in my Sister. She must have been teetering on the edge too because when I slammed tight against her she groaned and started vibrating from wooden leg to head. My sister came in sync with the hard-on pulsation in her.

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

Helen of Troy jerked the air sock out of her mouth and answered as calmly as she could"That fucking dog won't move dad."

We heard a piano chuckle"That's no reason to swear like that. Try to get some sleep."My relaxed prick slipped out of my sister's hole, followed by a laundry of semen. My baby turned over, put an arm over my pectus and hugged me while her breathing slowed to convention.

I fucked Helen of Troy twice more that Night and we managed to keep from alerting our parents to what we were doing. The dog slept carefree on my sleeping bag, my sister and I didn't get any quietus at all. Clarence Day later I overheard our father talking to our mother,"When we go camping with the kids again, we should involve another tent or sleep men in one, women in the other."

"Why ?"she asked.

"Because I found a enceinte soil in the bag mason slept in, he either had a wet ambition or masturbated. That's rule for an 18-year-old, but we should retain a distance between him and Helen of Troy from now on, she doesn't need to be exposed to his nighttime activities."

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