Open on Literotica

The Island: A Sibling Rivalry Tale

Lauren was in her string bikini, the one dad fucking hated.

It was even better than I could have hoped. In her never-ending quest to reduce her tan lines to as near to nothing as was possible, without violating state law, she had even left the straps that went around her neck untied.

Lately, her plump tits always seemed on the verge of spilling out of her top, but now they were defying the laws of physics.

Even her bottom half was indecent, the back of her swimsuit left about an inch of ass crack bare. Again, she argued that it gave her the best tan lines, but I knew it was because she liked having the eyes of every guy at the lake on her.

It was distracting that every time she turned her upper body to dig in her paddle I caught a generous flash of sideboob. I knew it was wrong to notice these things about my sister, especially given that they were starting to turn me on, but she was impossible not to appreciate. It was even more challenging after half a summer at the lake, now that her skin had turned a to a burnished bronze and her curved lines had toned up slightly from all the hiking, paddling and swimming our parents encouraged us to do.

It was made worse by the fact that I currently hated the conceited little brat she had turned into. I hated any power she held over me and her tits were, quite frankly, an unfair advantage in our ongoing feud.

The island was close enough that you could swim to it from the shore, but it was around a bend and a good long stretch of paddling away from the lakeshore. Few people ventured this far away from the cabins, but we had been going there for years. First, as kids, pretending we were pirates, and the later to get away from our parents and whatever activities they had planned for us.

My sister and I fought a lot, often to the point where it got physical. She was a lot smaller than me, but that girl could throw a punch. When we were little I would even wrestle her just to torment her and to reminder who was stronger. I always won, I weighed nearly twice what she did, but more than once I was surprised by the compact power she had stored in that little frame.

"Are you sure they have booze?" She half turned as she spoke, showing me her profile.

"They said they had a bunch of it and wanted to party."

"Did you have to suggest the island?" I hadn't, but she did not need to know that. Not yet anyway.

"Can you think of another place we can drink and not risk getting caught by our parents?"

She mulled over this while we paddled in tandem against the slight wind chop on the lake surface.

"Yeah, okay. I just kind of always thought of it as our secret place, you know."

"Loli, I'm pretty sure other people know about the island. The lake is big, but not that big. Remember, we used to find old campfires there all the time?"

"I guess," I was surprised by her nostalgia. Lately, we had not been getting on at all. Honestly, she had turned into a real bitch since this holiday began and she had noticed that every guy within a hundred miles could not stop staring at her tits. From being my dorky little sister she suddenly seemed desperate to fit in. It was getting painful and she needed a lesson in humility.

She had been all sweetness and rainbows with me today though, when I had invited her for a secret drinking session with my buddies. She was always desperate to hang out with them, probably because she had a thing for Ryan. She always mooned over him when he hung out with me. It was so embarrassing, I can't tell you how much it annoyed me.

A short while later we gave a last spurt of effort and paddled the nose of the kayak up onto a beach of scrubby plants and shaly sand. I hauled it a little further up the beach, leaving the tail of it still floating in the water.

"Where are they?" She stretched out a crick in her lower back and I had to turn my head so I did not have to stare at her flat tummy and the way her breasts perked up towards the sky as she arched her back.

The piercing in her navel glinted tantalizingly in the sunlight, like a lure to a fish.

I had to remember my mission.

"I told them to meet us at the mermaid lagoon," I flushed a little when I saw her grin, adding, "I didn't tell them it was called that."

Many of the landmarks of the island had retained the names we had given them in our childhood, despite their now, apparently, laughable naivete.

She walked up the steep shore, with me following close behind her. Apart from the barely existent bikini, she wore only a pair of pink aqua shoes. As she climbed I was unable to stop myself admiring the sway of her hips and the jiggle of her buoyant backside. She had blossomed remarkably this year and it annoyed me considerably that all my friends had begun noticed too. Worst of all, I had begun to find myself agreeing with dad about her choice of slutty outfits.

Away from the water the sun seemed to bake down on us with increased ferocity. Insects whined loudly around us, occasionally forcing one of us to slap at a stinging bit of exposed flesh. I began to regret leaving my shirt back at the cabin. I could see the sweat beading on Lauren's lower back, making her flawless skin glisten in the bright summer light.

She turned back at one point and caught me staring full on at her ass, but her only response was a knowing smirk. It only increased my resolve for what was to come.

Annoyed, I pointedly ignored her as was walked inland. Mermaid lagoon was only a few hundred yards from our landing site, over the shoreline's escarpment and along a short, overgrown track and then down to a wide basin. It was not so much a lagoon as it was a large puddle.

Lauren stopped on the small rise from which the stagnant water was visible. Without turning she said, "I guess they aren't here yet, huh?"

"Nope," I replied as I drew up behind her.

The time had come to claim my revenge.

I took a moment to plan my next movements carefully while she took in the vista around us. I checked all the securing points and ran over my actions in my head.

I knew from experience that she was quick, so my timing had to be good.

Bracing myself, planting one foot a shoulder's width behind the other, I flicked out my hands. With each one I took hold of the ties on either side of her bikini bottoms and pulled sharply outwards.

The tiny garment seemed to melt off her body.

"Hey!" She squealed as her starkly white ass was revealed, the bottom half of her suit now clutched tightly in my hand. Her shock had been something I had been counting on. While she hesitated between trying to take back the suit and covering her sudden exposure, I grabbed at the string of her top and yanked that too. It came away with surprising ease.

"Chaz, what the fuck?!" Lauren spluttered as she half turned, incredulity inscribed on her face.

I caught a glimpse of her fattened tits, perfect in their orbicular regularity. Her pink nipples seemed dark against the untanned skin the surrounded them. I had little time to enjoy the sight, firstly because she was already moving to cover them up, and secondly because I was also turning, and launching into a run.

"Revenge, bitch!" I yelled back over my shoulder as I sprinted off back the way we had come.

To my surprise, I hadn't gone far before I heard her thrashing through the low brush behind me. Seeing her running naked would have been worth seeing, but I had to keep moving. She was faster than I remembered.

I leaped down the sandy hill that led to the little cove where our kayak rested in a few huge bounds. I threw Lauren's swimsuit into the front of the kayak and shoved it out. The oars were still stowed inside the boat, so all I had to do was climb aboard and I my getaway would be complete.

That was when I was hit by tackle any cornerback would have been proud of. A hundred pounds of naked woman-flesh knocked me off the kayak, just as I was putting my full weight on it.

Lauren and I went down in a spray of water.

I was still trying to rise to my feet, spitting out a mouthful of lake water, when she came at me again.

"Asshole!" She screamed, "What the fuck are you doing?"

The water was only up to our waists, so I caught a full view of her swaying bared breasts as she threw a fist at me. I might have blocked it if I were not so distracted. As it was the blow clipped me painfully on the ear.

Knowing how hard she could hit, I did what I always did when we had fought as kids, I moved in close.

A little discomforted by her bare skin, I wrapped my arms around her and pulled her into a hug before lifting her off her feet. She kicked and squirmed against me.

She was slippery with sweat and sunscreen. Her bare tits were flattened against me. I could feel her nipples, hardened by the cold of the water, poking my chest.

I tried to ignore it, but my body was starting to respond. She was strong and had already managed to wriggle her way half free, when I hip-checked her and sent her under the water again. I thought it would give me enough time to get the boat, but once again she surprised me.

I had barely turned when she came out of the water like an alligator, leaped onto my back and got a stranglehold on my neck. I could not shake her off, restricted as I was by the water.

"Why did you do that you that, perv? Did you want to see me naked?" She shouted in my ear through her pants of exertion.

"It's payback you little bitch. For what you did at the campfire."

"The campfire?" She clearly intended to sound outraged by whatever reason I gave, but I heard the realization dawning in her voice.

"Melanie was there, you fucked up everything!"

"Melanie Rogers?" Even in the heat of the struggle she sounded surprised.

"Yes, Melanie Rogers. And now her and all her friends and pretty much everyone at the lake has seen my dick because you thought it would make you cool if you pantsed your big brother."

"So you planned to leave me naked out here, marooned on an island? That's some fucking escalation, Charles" She did not sound pleased. At this reminder, and the feeling of her naked body coiled around mine, I felt my hardness increase. I willed it down, I could not be getting a hard-on for my little sister.

"You can swim to shore. We did it a million times as kids. But you'll have to do that, and the long walk of shame home through the entire camp, buck-naked."

"Maybe I would have, but you forgot that I ran track in high school. Now give me back my clothes, asshole."

"Too late," I laughed, pointing to where our kayak now spun lazily out from the island, picking up speed as a breeze ruffling the water caught it, "Your suit is in the boat."

I expected her to deflate at this realization, but she surprised me again. I felt her hold around me tighten and heard the vehemence in her voice as she growled, "Well then, if I am going to be humiliated, so are you."

"What? But you already..." My protest was cut off as she clambered, monkey-like up my back. She dug her toes into the crack of my ass and began to put her full weight down on my boardshorts.

"Hey," I yelled, "Quit it!"

"Fuck you, you little perv," She spat back through gritted teeth. She had a tight grip on me now and I could not throw her off.

She jumped up and brought her full weight on my shorts. The velcro securing them, as well as a length of the seam, gave suddenly and they slipped down my hips. My erect cock spilled out and I dropped low in the water to hide it from her. She could not see that this fucked up sibling wrestling match was turning me on.

In the process she lost her balance and I was able to swing her around in front of me.

I shoved her roughly away and scrambled to pull up my boardies. I could feel, however, that she had ripped them badly. I had little time to dwell in this though, because Lauren came back at me almost immediately. The girl would just not give up.

She came in swinging, and shouting, "You are such an asshole!"

"Me?!" I yelled back, as I fended off her attacks, "You are the one who has been acting like a total bitch all holiday. All you've been trying to do is impress my friends by making a fool out of me."

"Well, now you know how I feel. What do you think you did to me for the last ten years of my life? Huh?"

"Fuck you!" I shouted back, but something about that last comment threw me off balance. Was she right? I had a flash of our previous summers here. All the times she had tried to tag along with me and my buddies, how I had ridiculed her, found ways to leave her behind and had teased and taunted her mercilessly for the amusement of my friends.

I didn't want to think about it. Most of all, I did not want her to see my inflamed dick. What if she told our parents? I had to get out of there.

Taking the fight to her, I stepped forward and shoulder charged her. As I lifted her out of the water she rained blows down on my spine. I gripped her around her chest, accidentally grazing the pliant flesh of her breasts, and then flung her away into the water.

Then I spun and began to retreat rapidly towards the shore, trying, unsuccessfully, to pull up my shorts as I waded. The worst of it was that they were now acting like a sea-anchor, slowing me down even more as they bulged with water.

I had just grabbed at an exposed root sticking out of the sand that I could use to pull myself out the water when she was on my back again, clawing scratches into my skin with her fingernails.

I was starting to think she might be some kind of cyborg sent back from the future. The kid had tenacity.

"Dick muncher! Cock Gobbler! Ass bandit!" She yelled, punctuating each insult with a blow to my back. Each strike she landed stung something fierce, so I instinctively twisted to catch her little flailing fists.

Bad idea.

As I turned I lost my balance in the muddy lake bed and fell on my back, with her still atop me. The water was shallow enough that most of our bodies were out of the water. Her strong legs were gripping me at the hips and she had a hand raised in preparation to land a slap.

A slap that never came.

We both froze. In the same moment we had become very aware that we were both completely naked.

Neither of us dared to move.

Then, slowly, as if by agreement, we lowered our respective gazes in unison.

My little sister was astride my hips and, to my horror I could both see, and now feel, her bare pussy on my rock hard shaft. It was positioned as if it were planting a very tender kiss on the underside of my cock.

I could not help but take a moment to take in her beauty. Her breasts had budded into their full ripeness, emphasized by her sharply defined tan lines. Her little belly was flat, with just the barest hint of the puppy fat that had melted away over the previous year, and it ended in a small, but untrimmed patch of pubic hair, sharply contrasted with the milky skin around it.

Her pussy lips were puffy and seemed to be trying to clamp around the cylinder of my shaft.

There was an ache in my chest when I truly realized for the first time, in that moment, how beautiful she was. It was made worse in knowing she was the one woman I could absolutely never have.

Lauren had turned into a statue, apparently, because she had not moved for the long moment I had hungrily ran my eyes over her. Her mouth hung agape as her eyes remained fixed on my dick.

Finally, after what seemed like an age, she spoke in a small voice, "You're hard?"

"Loli..." I began, having no idea how I could explain it.

"You're fucking hard for me?" She said it louder, with a little laugh of surprise before adding, "You are!" She beamed, "You have a hard-on for your little sister, you fucking perv!"

"It's nothing," I argued, my face burning red, "It's just a physical reaction, okay. You can get off now. It's nothing..."

My words were cut off as she suddenly dropped forward onto my chest. I let out a surprised "Oof," as her body thudded into mine. Only this time, instead of an attack, she pressed herself against me and kissed me full on the lips.

For obvious reasons, this stunned me more than any hit she had landed. I was too stunned to fight the intrusion of her tongue into my mouth.

Realizing a moment later what was happening I pushed at her shoulders, trying to raise her off me, but she resisted.

"Eww, Loli. You're my fucking sister. Stop it, okay."

She was grinning stupidly at me now and replied, "You can say what you want, but your body is telling a different story." For emphasis she lifted her butt and slipped a hand between our bodies. Her cool hand was suddenly wrapped around my shaft.

She lifted it, rubbing it against her sunscreen oiled stomach in the process.

"You like me, Charlie-boy," She whispered.

Slowly her hand slid up my length and then pinched the tip of my cock just the rough side of gentle.

I nearly exploded in her palm.

Both our mouths were open, we were breathing the same air. We were so close that when she moved our teeth clicked together. We each just had to lift our tongues a fraction and we would be kissing again.

I dared not move an inch.

There was a wickedness I had never seen before dancing in her lapis lazuli eyes.

It was so incredibly wrong but, this time, when she slipped her tongue into my mouth I kissed her back.

It was a long, sensuous kiss. The skin prickling heat of the sun contrasted delectably with the cool, silky water, making it easier to let her fall into me.

She moved her hand so that our bodies could adhere together once more. Her hands sank into my hair and held me tight, tilting my head so that she could kiss me even more deeply.

I, for my part, slowly let my hands descend from where I had been holding them out in a defensive gesture. Tentatively I let them rest on her skin. It was hot to the touch and perfectly smooth.

When she broke the kiss next she breathed out, "God, I've wanted to do that for the longest time, Chaz."

"I... I..." I stammered.

"What the actual fuck?!" Was what I wanted to shout, "My little sister had been fantasizing about me? But then why was she such a total bitch to me all the time?"

I could not deny that I had noticed my sister. She had, in a very short time, turned from a gawky teenager into a ripening woman of surpassing loveliness. But she was my sister! The rules are that you have to pretend like you do not notice her cleavage, or her pokey nipples, or what the lycra of yoga tights does to her ass.

You are supposed to banish the thoughts of that time she left the bathroom door ajar and you glimpsed her peeing with her panties around her ankles.

Especially when you are jerking off in the shower.

You are supposed to, but that is not realistically possible.

I could feel her tits sandwiched between us.

I could feel the soft fuzz of her pubic hair tickling my stomach.

Shit, I could feel the heat of her little pussy against my cock.

My sister and I were naked and we were making out like lovers.

I tried to move, turning my head so that those damn pouty lips of hers would not draw me in again, "This is wrong, Loli, we shouldn't."

"Who says?"

"I don't know. People. The law. God."

She turned her head from side to side, forcing my breath in the sweet coconut scent of her hair.

"I don't see any of them here, Chaz. This is our island, remember?"

"Loli, seriously. This is fucked u..." Again my voice trailed off as she gave a small rock of her hips, using her pussy to stroke my shaft.

"You like that, Chaz?" She asked.

My only answer was a groan.

As she used the greased smoothness of our bodies to slide over me in a languid, sun-warmed glide she said, "I can't tell you how often I dreamed about this, Charlie. Dirty, wicked dreams."

"Seriously?" I finally managed to gasp out, "I thought you hated me? You certainly acted that way."
"I just wanted you to notice me. Why do you think I tried to hang out with you and your stupid friends all the time?"

Between words she nuzzled my neck, planting kisses along my jawline. I wanted to fight her, I really did, but my body was working against me.

I could feel her lips on my Adam's apple when I replied, "But, I thought you liked Ryan. That's why you were always flirting with him."

"Ryan?!" She forgot about being sensual in her incredulity, "I only did that to make you jealous. You look so cute when your jaw clenches. It does that every time one of your friends tries to look down my cleavage. Ryan is an idiot. I could never date a guy who, despite being shown all the evidence to the contrary, still argues that Washington DC is in Washington state."

I felt her hand slip down and then it was cradling my balls, playfully tugging at them.

Jesus, my little sister was playing with my balls.

"I tried everything to get you to see me as I see you, but you were such an asshole to me. I was just your bratty little sister. I only pantsed you because you had spent the whole day before the campfire patently ignoring me." She emphasized her points by squeezing hard on my balls.

"Jesus! Ow! I'm sorry, Loli. I didn't mean it. It was just, you know, older brother stuff. Ouch! Can you let go now?"

She made a great show of mulling over this prospect and the way her eyes narrowed and her nose crinkled when she did this was suddenly the sexiest thing I had ever seen.

"Do you still see me as your bratty little sister?" She asked, comically batting her eyelashes.


"How do you see me then?"

When I didn't answer she lifted her chest off mine and, taking her weight on one hand, used the other to grip my wrist. Slowly and deliberately she raised my hand up to her breast.

"Fuuuck," I moaned as my hand cupped her firm, full mound.

"How do you see me, Chaz?" She repeated the question.

"Beautiful," I choked. I was not sure it was in answer to the question.


"The most beautiful woman I have ever seen, okay? I fucking hate that you are my sister, Loli. It drives me insane. This whole vacation all I could think about was your sexy little body, and all you did was flaunt in front of me and every other guy within a hundred miles. Do you have any idea what that is like? Do you have any idea how it made me feel, that all I could think about every night is bursting into your room, tearing off your pajamas and fucking you on your bed, even with mom and dad in the next room?" My confession poured out of me in a rapid flurry of words.

Lauren, for a response, gave me her warmest, most genuine smile before bending down again to place a small peck on my lips.

"That's the right answer, Charlie-boy," She giggled, releasing her tight grip on my testicles.

"Oh," She added as she breathed into my ear, "And, I don't wear pajamas."

I let out a small whimper.

She sat up then, giving me all the time I wanted to run my eyes over her incredible body. I let them roam from her face, half hidden by the dark wet hair that had fallen across it, to her breasts, which seemed a size too large for her slender frame.

She still clutched my outstretched hand to one breast, the puffy pink nipple peeking out between my fingers. I desperately wanted to rub my tongue over it.

The flat plane of her belly ran down to where our bodies were sinfully touching. I wanted to bury my nose into her sparse little patch of pubic hair and breath in her scent.

She lifted my hand off her breast. I tried to resist her, but she drew if forcefully to her mouth and proceeded to suck on my finger.

Then she began to move her hips. Her hot, wet little pussy slid up my shaft with greased ease. As she moved lazily atop me, she lowered my hand again and guided my finger in a slow circle around her sensitive looking areola.

I moaned. Loudly.

I tried one last time, my resolve crumbling, "Loli, this is wrong."

"Maybe that's why it feels so good."

I could actually feel the little dip each time her entrance slid up to, and then briefly cupped the head of my cock, before sliding away again.

Lauren shamelessly rode me, grinding her pussy along the edge of my cock, like she was sharpening a blade. A blade I wanted desperately, in that moment, to impale her on.

Looking down at me she giggled, reminding me of how recently she had been but a girl to me.

The expression on my face must have been transparent because she laughed harder and asked, "Are you seriously about to come already?"

"No," I lied, trying to ease the rictus from off my face. I am normally not a minute-man. I have always had staying power, but that was before my sister. Her shy beauty stole the breath from me.

She batted the hand I had on her breast away and leaned in close again. Her grinning lips were just brushing mine as she said, "I'll tell you what. I'll let you finish what we started, but..."

As she spoke she sprang to her feet and turned. Before she dove back into the water she yelled, "You have to catch me first."


I lay there, half in, half out the water, utterly dumbfounded.

My cock was a fucking sundial.

"I really should just let matters rest here," I told myself, "That got a pretty weird, and some things were said, but it's not too late. You just have to lay here and not go after her. You literally have to do nothing to do the right thing here. Sure, she might be a little hurt. But it is the right thing to do. She needs to move on. Find someone else."

Even as this stream of reasoning battled to take control of my mind, my body was already lifting itself off the sand. That last thought, of her finding someone else, had stabbed a tender spot within me that had not been there a few minutes ago.

I watched as she came up out of the water, turned to look at me and laughed. When she dove under again she deliberately did it in such a way that her bare white ass came up, giving me a flash of her cleft and a little bit more, before it too disappeared under the water.

My thoughts switched over into background noise. Any consideration as to the fate of our kayak was erased and I leaped into the water after her, heedless as the force of it tore my broked shorts away. Now, as naked as she was, I stroked with fierce determination through the water. My undiminished hard-on slowing my progress.

I had to catch her.

I looked up to see her treading water, that big grin still on her face, not far from me. She was clearly waiting for me and, when she saw that I had spotted her, she struck out again, rounding a promontory of the island.

I knew where she was headed, and I smiled inwardly. She was trapped.

Rounding the corner I turned into a small cove.

When I got there I could see she was nearly at the Hydra.

Once, long before we had first come here, it had been a very large tree that grew on top of the island. But something must have happened: erosion, or a shift in the land, maybe even a storm. Either way, at some point, a slice of the island had calved away, taking the tree with it.

Now it lay on its side, dead and stripped of its bark. More than half of it was submerged and the bare branches that stuck out of the water formed smooth curves. With a little imagination you could see it as a many-limbed, writhing sea monster.

It used to terrify us as kids. We would challenge each other to see who would dare paddle the closest. But, now Lauren was boldly swimming towards it. Already she had slipped under an arch created by one of the branches. She was headed towards the center of the tree.

I cannot be sure if it was anger or frustration that drove me on. Perhaps it was both.

I moved slower now, knowing I had her trapped in this shallow inlet. I followed her into the tangle of tree limbs. The game had changed now. She too had slowed and swam only to keep the distance between us. When I moved, she moved. It was a game I grew tired of quickly.

When my feet found a submerged branch I stood on it. It was wide and a little slimy but, provided I kept my hand on another nearby branch above me, it was easy to balance on.

"I can wait here all day, Loli," I shouted at her, waist-deep in the water, "You have to come out this way some time, and when you do, I'm going to get you."

"What will you do if you catch me?" She asked, giggling.

"I...uh" I did not have an answer for her. I wasn't quite sure what I would do. I just knew what I wanted to do. But would I regret it forever? Would it later tear my family apart? My dad would literally kill me if he knew things had even gone this far between us.

"Come on, Loli. Let's get out of here. We just won't ever talk of this again. We're brother and sister." The swim had given me time to reconsider, this was something we could absolutely never do.

"Show me your dick."


"Your dick, show it to me."


"Prove to me that you're no longer hard for me and I'll go home with you and we'll never talk of this again."

I stared back at her in grim silence, not moving.

"I knew it!" She crowed, "You want this every bit as much as I do, Chaz."

"That's beside the point. We can't act on it. It's wrong."

"It's only wrong if someone finds out." She was swimming closer now. Suddenly I felt like the one who was cornered.

She had a conniving look on her face as she paddled smoothly towards me, saying, "And no one will ever find out. This is our island."

"Loli..." I began, but she ignored me and slipped completely under the dark water just a few yards from me.

There was a long stretch of quiet, while I waited for her to come up for air.

But, she did not resurface.

I was just beginning to worry when I felt something brush my foot. I flinched involuntarily, but then two hands were firmly gripping my legs just below the knees.

They moved up. I looked around, sure there had to be someone watching. But, Lauren was right. There was no one out here and, if there was, we would probably know about it before they saw us. Sound carried far across the lake.

I hissed as a warm hand wrapped around my cock in the cold water. I placed my hand over hers in an instinctive attempt to stop her.

Then it was as if a bubble of heat had engulfed the tip of my cock. I knew then that my sister had taken my dick into her mouth under water. I did not try to put a hand out to stop her this time. It felt too damn good.

There was a strong suction on me, delightful in its intensity and the attached sense of wickedness. If I was any sort of decent person I should not have let it proceed any further.

As it was, when she finally surfaced for some air - her lung capacity just one more thing for me to marvel at - I felt disappointment more than anything else. With just her head poking up out of the water, she grinned at me. It was a challenge. Her hand still gripped me by the root, giving little tugs and consistent pressure.

She held one finger to her lips as if to forestall any further protest I might have. Then she sank back beneath the surface.

A furnace engulfed me. It hit me like a wave of heat and tossed me around in its eddying currents.

Her tongue rubbed itself roughly on the underside of my cock. There was no timidity or caution to her blowjob. Loli seemed to want to own, and leave her mark, on every square inch of surface area my cock possessed.

A steady stream of bubbles came up from below.

The spell broke again far too quickly, her breath running out, and she popped up again to suck in great lungfuls of air.

"Jesus, Loli. That's incredible." I said.

She shrugged and looked away a little shyly at the compliment.

"But I don't want you to kill yourself." I couldn't believe I was going to suggest she stop. But, before I could do so, she grabbed me by the shaft and pulled me forward, none to gently.

I followed, not able to do much else, as she led me further along the tree limb I stood on. The branch above us ran almost parallel to the one I stood on, so I could keep a hand on it for balance.

Treading water, Lauren led me like a scolded puppy until the branch began to rise to the surface. I no longer had the will or inclination to stop her. She halted me just short of where the tree limb snaked out of the water, when everything above my knees was above the surface.

I looked down disbelieving at the sight of my tumescent cock clutched in my sister's small hand.

Then I watched with undisguised lust as she took hold of the tree limb and shimmied her naked body out of the water, paying close attention to the flexing of her taut backside and trying to glimpse her perfect little pussy again.

She struggled awkwardly for a moment, taking my proffered hand for support, as she turned. Then she straddled the tree branch as if she were on a pony. The branch was thick and her legs had to spread wide to go around it. I stared, slack-jawed at her slightly spread labia.

The downward slope of the tree branch meant she had to put her hands on my hips to keep her balance. I, in turn, braced myself between the top and bottom limbs I was using for support, pushing out my hips to meet her weight.

Her eyes did not meet mine. Instead, they were solely focused on the hood of my cock, which bobbed and twitched involuntarily just a few inches from her face.

Tenderly, she leaned forward and placed a small kiss on my tip.

I swore softly.

Her eyes flicking up, while she clearly fought to contain the smile spreading across her face, I watched in mute fascination as she opened her mouth and let my dick come to rest on her tongue. It curled up and folded around me. It slid upwards until my heavy shaft fell off the tip and bounced. She repeated this several more times before she began to rasp the roughest part of her tongue against the sensitive underside of my glans.

I used a finger to brush a wet strand hair off her face. She was so beautiful I wanted to see her, all of her.

Smiling blue eyes looked back up at me as her mouth opened a little wider and she began to stuff my length between her inviting lips.

With her eyes closed, and a look of contentment on her face, she began to very gently suckle on my cock. It was so sweet and tender, more loving than any blowjob I had ever received.

I had my hands up, on the tree limb above. My body felt good, stretched as it was with the sun on my back, the knotted muscles on my stomach standing out proudly.

Unable to stop myself, I began to move my hips. I used what little leverage I had to begin pumping myself into her mouth with growing determination. For her part, she seemed to welcome it, her hand joining her mouth in the effort to milk everything out of my cock.

I let her slowly and opulently bring my orgasm up like something from the bottom of the dark lake waters. Slowly drawn up from the depths, it seemed to increase in pace and urgency as it sensed the promise of light and heat from the sun high above.

"I'm going to come. Loli," I warned her, my hips stuttering in their short thrusts.

For answer, she used one hand to grab my testicles and tug downwards and she sucked down hard on me, cheeks inverted with the force of it.

The sound of my shaft slotting with a liquid "Schlock. Schlock." into her mouth was enough to set me off on its own. It sounded much louder in this quiet little shelter from the breeze.

I let out a sound somewhere between a yelp and a growl as I felt the bunching up of tension in the head of my cock.

My orgasm came like the first taste of sweet air after being under the lake so long your lungs had begun to burn. I unloaded into her mouth in a spattering gout of release. She slurped noisily at each fresh lash of come that jettisoned out of me.

I could feel my nails gouging marks in the softened wood of the tree as my body clenched tight, every muscle rigid and standing out like bundles of chords.

"Jesus, Loli" I panted as I fought to regain control of my trembling body, "That was... Something else."

She seemed pleased with herself and kept teasing me by leaning forward to kiss my cock, even though she could see it caused me discomfort.

I wondered if she would suddenly feel shame at what we had done, if she would back off and show regret. But that was clearly far from her mind. Instead, she leaned back on the tree limb on one hand, and used the other to spread the puffy lips of her pussy, showing me the deep pink hidden in her folds.

" Still thinking about Melanie Rogers?" She asked with forced casualness.

"Who the fuck is Melanie Rogers?"

Her grin returned and she said, still toying her slit with one finger, "I think you owe me, Chaz." She purred as she let that finger slide up and down the crease while the others held back her labia.

Dumbstruck, I nodded, my eyes locked on to her perfect sex.

She stopped and seemed to think for a moment, looking around her for something. When she spotted whatever it was she reached out and took my hand. I was too deep under her hypnosis to do anything other than obey her.

Together we slipped back into the water, the coolness wonderful on our sun-warmed skin. We paddled cautiously to avoid the hidden branches below the water.

She took me to the wide bole of the tree, from which all the many branches around us originated. I saw now where she was headed. A section of the toppled tree was scooped out in a bowl shape, around which many of the branches connected to the main trunk. If we had been brave enough to venture in here children it would have made the perfect fairy throne for one of our fantasy games. As it was, it made a pretty good seat.

Lauren started to pull herself up into it, but I grabbed her by the hips as soon as her bare backside broke the surface and let my fingers dig deep into her firm flesh.

I had been waiting my whole life for this moment, even though I had not realized it until now. I could not wait a second longer.

"Chaz...?" She began to ask, but the trailed off into a long, "oooh," of surprise as I buried my face between her cheeks.

I was too far gone now, I wanted to possess every part of her and make it mine. I had never done anything like that before, any oral sex I had performed until that moment had been entirely vanilla.

Now I was running my tongue up her crack in broad, flat strokes. I would start by thrusting my tongue into her pussy, and sucking in her wetness, tasting the water of the lake mixed with her juices, then I would move upwards slathering her valley with saliva, rolling my tongue over the little depression of her asshole and upwards.

I licked her out like that until she was making little whimpers in her throat. The suddenness with which this ferociousness had taken over me was surprising for both of us. My body seemed to be telling my mind I should have realized this was what I wanted a long time ago.

I probably could have let her climb out of the water and allowed her lay back comfortably in the embrace of the tree, but I was ravenous now. The taste of her overwhelmed me.

Instead, as she lay half out the water on her stomach, I shoved her right leg up by the thigh until she let her knee rested on the ledge with her upper body.

Her pussy was now opened before me. I stared, fascinated at her spread legs and the parted lips of her sex, which glistened in the sunlight. The pose emphasized the generous curve of her perfect backside. I let my hands dig into the dense flesh of it, using them to pull my face up to her dripping sex.

I was still in the water up to my shoulders, but I managed to find some footholds. It gave me the leverage I needed to burrow my face into the gap between her thighs. My nose was now between her ass cheeks, while my mouth formed a seal around her tight little entrance. My tongue, meanwhile, began to thrust into her, testing the constricting tightness of her.
I munched on her in the sloppy way I would have if I had to devour a mango with my hands tied behind my back.

My dick had already swollen back up to its full size, plus what felt like a little bit extra I had reserved only for my sister.

Being in the water, I could let her juices and my saliva grease my face, drip off my chin, and onto my chest without concern. It was oral sex at its most uninhibited. Seeing as we had already broken so many taboos I felt no reservations in taking complete ownership of her body.

The hollow, wet sounds that were made by my mouth on her sex reminded me of an animal gulping down its feed. Which, given that she had turned me into a starving beast, seemed appropriate.

When I finally regained some semblance of control I let my lips continued to nibble and pinch her folds of skin, while my tongue slid forward into her cleft, parting her labia. I had to tilt my head back and open my mouth wide until my tongue found the little bump just above her little fragile hood of skin.

I prodded the tight bundle of nerves and felt her body respond. Her ass flexed, pushing my fingers out of the depressions they had made in her skin. Her tight belly muscles gave a flutter like moth wings against glass.

"Oh fuck, Chaz," She moaned, "This is... it's so... I can't believe this is finally happening."

She seemed to melt and reform around my tongue, giving me access to her most sensitive parts without any effort on my part. Her proud clitoris stood up to greet me, rubbing itself on my tongue like an affectionate cat.

I slid myself as far under her as I could, my neck starting to take strain, but I could not have cared less. Her hips were bouncing up and down on my face now. What little finesse I had was gone, all I could do was nip and prod at the slippery flesh that came into contact with my mouth.

Apparently it was enough because I felt her body buck hard. I nearly lost contact with her, so I gripped her ass as tight as I could, adhering my face to her quivering pussy, even as her hips thrashed my head around.

"Chaz!" She screamed, heedless that there might be anyone nearby who might hear us.

She came so hard her body beat at me as if she were a landed fish. I felt the contractions of her pussy under my tongue and her ass juddered in a thousand tiny micro-flexes beneath my hands.

Even as the convulsions stopped she continued to smear her sex over my face, now sticky with her juices, it lazy circles.

Feeling an incredibly warm pride settling in my chest that I had been able to make my gorgeous sister climax so hard, I sank back into the water. I put my feet up on a branch and lay back, using just my hands to keep me afloat.

I was sure I would feel terrible shame and guilt for what I had allowed to happen later. But for now the afterglow of what I felt blazed brighter than the sun overhead.

I heard a stirring in the water and looked up just in time to see Loli dropping back into the water like she had been poured off the tree. Dreamily she made her way over to me. I expected her to say something to mark the incredible divide we had just crossed, and could never go back over, but she just kept swimming right up to me until our faces came together.

She kissed me, each one of us still tasting of the other, and as she did so she wrapped her arms around me.

We immediately sank beneath the water, my body unable to hold the weight of both of us up.

As we descended we kissed long and deep, while her small, strong body curled itself around me. I had never felt so close to anyone before, she just seemed to conform perfectly to me. I lost track of how long we stayed under, but when I finally kicked us back up to the surface, we both took in long, deep breaths to recover.

When I saw the enormous grin on her face I could not help but laugh. She joined me and kissed my mouth again, then my cheek and down the line of my jaw.

Her legs wrapped tightly around my hips and I had to work hard to keep us both afloat. My reawoken cock was crushed between our bodies.

She seemed oblivious to my struggle to stop us from sinking. Her hands held my cheeks and pulled me in again for another passionate kiss. Blindly I fumbled for the tree. After a few misses, my hand finally came down on the algae covered wood under the surface. I used this to pull me closer until my feet found the limb and I could stand, using the hollow I had pinned her down on earlier to steady myself.

As our bodies rose out of the water she lifted herself up with her hips and brought her kiss down on me from a higher angle. I tried to lift her off me gently, so I could position us more comfortably, but she resisted fiercely, pulling me tighter into the kiss. It felt so incredible I did not try it again. Instead, I revolved my body and put my back to the hollow.

She was so tightly coiled around me I could use both hands to lift my backside up into the depression in the tree.

Humming sweetly, she lowered herself into my lap while I settled into our throne, our kiss never breaking, our tongues writhing over each other.

I ran soft fingers down her spine, feeling the undulations all the way down to the cleft of her backside. My other hand stroked her flank, drawn to where her soft breast bulged outwards from between our flat-pressed bodies.

When my left hand found my hard cock it pulled it in close and wedged it between her ass cheeks. I made a bridge with my hand over the valley to keep my manhood in place, then I began to rock back and forth gently. She clenched her bottom tight, squeezing down hard on my shaft.

Then I was kissing down her chin. She let her head fall back, exposing the full length of her elegant neck to me and I kissed a line down her throat to her collar bone. Eager as I was, she raised herself up on her knees and brought her magnificent bosom up to me.

She presented first her right breast, which I anointed wetly with my tongue, and then her left, which I treated with similar reverence. Her areolae were so puffy that her nipples barely seemed to rise above them. But, when I used the tip of my tongue to curl under one, it lifted and swelled to attention.

I tasted her sunscreen and the salt of her sweat, which the lake had not washed away completely. As I gave those perfect nipples the full extent of my focus she dug her fingers into the hair at the back of my neck, turning my head so that she could run her tongue in a rough circle around my ear.

It seemed to further awaken the animal inside of me.

I sucked in a great bulge of her fatty tissue, squashing it flat between my lips and lapping my tongue over her newly puckered nipple.

She gasped and rolled her body against me like a crashing wave.

My dick slipped out from where it was being rubbed against her ass. But, before I could try and reset it into position she grabbed my hand and looked down into my eyes, hers burning with a fierce intensity.

"I want you inside, me Chaz."

"Are you sure?" I tried to ask, but with her breast still in my mouth it came out "oh oooh ohr?"

I already knew I wanted it more than anything I had ever desired in my life. I was too scared to admit that though, this sudden awakening of emotions was too powerful. I was in danger of being swept away.

Apparently she understood me because she answered, "I've never been more sure of anything Charlie. I've wanted you for the longest time. I don't think I could settle for less now."

When she saw there was still hesitation in my expression she added, "Relax, I'm on the pill."

Then, after a brief moment, she added, "But, just to be safe, maybe don't come inside?" It came out as a question, but I understood her concern. It caused me physical pain to consider that conclusion, but I knew she was right.

I nodded, her tits bouncing along with the motion.

She smiled nervously, and her eyes widened, "Okay," she said, more to herself than to me, "Here goes."

She rose up on her knees and positioned her ass over me. Then reaching behind her with her left hand, she gripped my pained cock and lined it up with her entrance.

By some silent agreement we both looked unblinking into each other's eyes. With slow deliberation, she lowered herself onto me.

As she did so I tracked every micro-expression that played out across her face, from her initial nervousness, to renewed self-reassurance, and, finally, a small grimace of pain as she strained to insert my thickness into her narrow opening.

"I can't believe we're actually doing this," she breathed out. "It feels unreal." I could only murmur assent as I felt her body resisting mine. Was this one last reminder from the universe that what we were doing was against the natural order? Or was she, on some level, reluctant to complete this dark tryst?

These doubts, and more, plagued me, until I felt a shift, like the right key finally being fitted into a lock, and she sheathed herself on my length in one long smooth descent.

We sat like that for a long while. Looking into each other's eyes, each worried the other might break or lose courage, but neither of us did. Her body squeezed mine in a smothering embrace. The tissues of her inner lining pulled in tight around me, as if trying to make sure that every square inch of me came into contact with some part of her.

It was the most tender I had ever felt towards anyone. She was wrapped around me on so many different levels and I was terrified how it would feel to be separated from her again.

She had been right in front of me the whole time, but I had only just found her.

Unable to take the incredible intensity between us any longer I finally broke the silence, asking, "I'm not the only one feeling this, right?"

She smiled and shook her head. There was the glint of tears at the corners of her eyes. Was she close to crying?

Now that I thought about it, there was a lump in my throat too. This was something so beautiful perhaps we were the only two people in the world who would ever know it.

"This is not like any time I've ever done this before. Not even close. Those were like," I searched for a metaphor, "like elevator muzak. This, Loli, this is a full symphony orchestra."

She sniffed and nodded, Her smile pulled adorably askew by her raw emotion she was experiencing.

We hadn't even started to move and already it was the best sex I had ever experienced. Probably because it was not about sex, it was about a connection of fathomless depth. A connection that had been covered over and left dormant for most of our lives but, when the debris was cleared away, it had revealed itself to be unbreakable. Now it had brought us together and made us as close to oneness as could be in two imperfect human bodies.

"I love you, Charlie," Her voice was choked and so soft I could barely hear it.

"Loli.." I sighed, "Fuck." I shook my head and the added, "I think I feel the same. I mean, damn, this is all so sudden and unexpected, I need time - a lot of time - to process all this. But, this is on a whole other level. I didn't know anything could feel this... incredible."

She kissed me again, not passionately, but with an aching sweetness. It was just her lips pressed to mine, but it hit me like a knockout blow. I lay back against the tree, not feeling the discomfort of the hardwood, and watched her begin to move.

Her tears were gone now, and her smile had returned. She put her arms up, wrapping her hands around her head and closed her eyes. She seemed to be listening to some secret song that made her body begin to sway entrancingly from side to side.

Slowly, and ever so gently, she began to circle her hips, using my shaft as the pivot.

I let out a sharp hiss at the feeling of her inner tissues rubbing against my hypersensitive hood.

Lauren had always moved with grace, but now she was making sex look like the most sensual dance I could have dreamed of. Her body moved like a flame. The rolling contractions of the muscles beneath her skin needed to have a poem dedicated to them. Every part of her seemed to be in sync with the others, allowing her to move with almost supernatural fluidity.

My little sister was some kind of sex goddess.

I was little more than a passenger along for the ride at first. All I could do was place my hands on her small waist and hold on tight.

Later, as she began to lift herself higher and then began to plunge herself down on my erection over and over, I was finally able to move with her. It was as if my body had been waiting all night for an invitation to join the dance and, for once, it knew all the moves.

Our bodies found the rhythm together almost instantly.

Each thrust of my hips happened in perfect counterpoint to hers, so that my cock went from being buried inside of her up to the hilt, to being on the very edge of slipping out of her at the end of each sequence. It was incredible to feel every inch of her with my entire length on each stroke, without a single short thrust or missed beat.

My hands were sliding up her water-slicked belly, to where they could cup the weight of her bouncing tits. My fingers searched and quickly found her nipples. They were clearly engorged now and well defined enough for me to tug at them between thumb and forefinger.

Her eyes were still closed and she was softly muttering words. I had no idea what she was saying, but every once in a while I heard a breathy, "Charlie."

It made my dick pulse each time I heard my own name.

She leaned forward and braced her arms against my shoulders, pushing me back into the tree. The angle changed and she now rode me like a derby winner. Internally, her body clung to mine, seemingly determined to absorb me into her. The traction between us seemed design to draw everything out of me.

I am not sure how long we remained fused like that, staring deep one another's eyes, lost in each other's bodies. It was as if we had reached some higher plane where the climax was not the end goal, the journey was already enough in itself. An orgasm just seemed like just a good, but very distant, way to exit this plane of perfection.

I loved how my body fitted perfectly into hers. The island, the entire world, was one vast empty ballroom and we were waltzing along to the most beautiful music either of us had ever heard.

It was Loli who finally broke from the pattern. I had felt her body changing around me. Her inner walls vacillated erratically and I had both the time and inclination to watch how her muscles had begun to bunch, as if there was some clockwork mechanism behind them gradually being wound up.

Gasping, she pushed herself back. Her breasts pulled free of my grasp and she fell back onto one hand. The other slapped down on the verge of her mound and curled inwards, digging into the supple skin between her folds.

The crescendo of her performance was one burned so brightly into my memory I take it with me everywhere. It is a singular treasure that I can pull out at any time and polish and, though it bears only a fraction of the lustre of that original moment, it is still brighter than any star in my memory.

The ecstatic contortions of her face only seemed to magnify her beauty. Her body shook and jogged, emphasizing every perfect line, swelling, curve, and slab of compacted muscle.

Her fingers were whirling around a small point just above where I was buried inside of her. As she wound herself up, her hips clamped tighter and tighter until she was no longer moving atop me, but had focused all of her energy into a single nexus point.

A sound started in the back of her throat, low and strangled. It rose in a long drawn out whine, rising and rising until it tore itself free from her in a scream that must have been audible back at the lake shore.

"Charlieeeeeeee!" She cried as her body first locked down tight around me and then began to shudder uncontrollably. She grunted and twitched in that drawn-out moment of undiluted euphoria, uncaring of how it twisted her face and hunched her body.

It was the most perfect thing I had ever seen. I might have climaxed with her if I had not been watching her with the appreciation of the most ardent patron. This was truly a form of art.

As her convulsions subsided she slipped forward and I caught her. But my body was catching up to my mind now, and it began to burn and tingle up and down my shaft. The eruption was well past due, I was surviving on borrowed time.

Quickly I sat up and pushed her back. She flowed off me and arched her back over my knees, her hair actually brushing the surface of the water. When her hips lifted I slid free of her. My dick was painfully engorged, angry in its blood infused state.

I was gripping it, preparing myself for the finale, when she pulled herself up. Her abs announced themselves in the motion, while her hand reached out to grasp my dick.

"Mmm, Charlie-boy," She moaned, "Do it for me, I want to feel it on my body."

I was already so close, and her words were like the final trigger. With only a few quick pumps of her hand, I exploded.

A high arc of come shot out of me. It laid out a straight white line from her belly, over her chest, her face and ended up curling over her hair.

A second followed, and what it lacked in force it made up for in volume. It landed with a heavy splat on her ridged belly and quaking tits. It ran between them and down toward her collar bone.

Her exhausted muscles were finally relenting and I had to grip her thighs painfully tight to stop her sliding off me into the water. As it was, her hand had tiredly pulled my cock down to where it rested on her pussy like a stock. The remaining spurts lanced out at a low angle, scorching lines down her abdomen before splashing off the underside of her breasts.

Having disgorged my entire load and, what felt like, considerably more, I sat up and shifted my position so that she lay back over my knees. My semen, which now coated her body, quivered, jelly-like, while her chest expanded and fell rapidly to haul in air.

"My God, Loli." I panted.

"I know, right?"

With my last ounce of strength I leaned forward and gripped her shoulders. I pulled her up into a sitting position and then flopped over backward with her atop me.

We lay like that for ages, her curled up and wrapped up in my arms, my seed sticking out two bodies together as it dried in the hot sun.

When I turned my head I could see she was staring at me. Staring and smiling. I darted forward and placed a small peck on her nose.

"That might actually be worth going to hell for, little sis," I teased.

Laughing she slapped my chest lightly, replying, "Stop it."

There was an awkward moment when the laughter stopped and we were both forced to break eye contact. I knew this was the moment that could unravel everything. We could let it spin out of control and we could lose this contact we had so newly forged through shame and over-consideration.

I could not let that happen, this was something I wanted to hold on to with everything in my being.

I squeezed her tight and kissed the top of her head. It was hard to say, mostly because it was the truth, but I forced it out anyway, "I love you, Lauren."

It was the right thing to say. She tilted her head up, her wide eyes making her seem even younger than she was, and asked, "You do?"

"Yeah," I replied with iron-hard confidence, "I really do. I mean, I think always have, even when I was being a dick to you."

"So you admit it?"

"Yeah, I guess it was my way of keeping you distant. Keeping myself from falling in love with you. Too late to worry about that now though," I chuckled as I hugged her to me.

This seemed to satisfy her, she snuggled contentedly into my chest and used her forefinger to draw small circles in my sparse chest hair. "Well it's about time," She murmured.

I did not need to see her grin, I could feel in where she was pressed into my skin.
"Just do me a favor?" I added.

"Hmm," she murmured sleepily.

"If you ever want to get physical again, let's rather work out our difference in this way. It's far more enjoyable than fighting."

"Deal," she responded, "Besides, I wouldn't want to break this body, now that I have finally found a use for it."

I laughed and held tight her and tried not to think about when we would eventually have to let each other go.

Eventually, as the afternoon cool set in, I felt her shiver and we were forced to sit up. We laughed when we realized my dried come had partially fused us together. After separating ourselves we slipped into the water, unwilling to let our bodies lose contact with each other as we swam back to where our fight had started.

My boardshorts had washed up nearby but were mostly ruined. We reasoned that, if I held them up with one hand, I would be able to make my way, with some difficulty, back to the cabins without further exposing myself.

There was still the matter of dad's kayak though, and Loli's swimsuit. Together we swam from the island to the mainland. We spent a good hour picking our way down the shoreline until we finally found the boat, where it had gotten snarled up in a tangle of brambles that grew into the water.

We retrieved the kayak, and Lauren's bikini.

Now, as decent as we could make ourselves, we made the long paddle back home as the sun began its final descent in the sky. When we arrived we were cold and tired, but simmering with a secret elation that only we knew of.

On the trip back we had agreed that, while we could not deny the magnitude of whatever we had begun out there, it was something we would have to keep secret. No one would understand it, least of all out parents.

Our island was where it had begun and our island was the only place we would allow it to continue. It would be our secret paradise.

There were still many days left of the vacation, and we reasoned we could get out there several more times before the summer ended. We promised ourselves that we would be cautious and stick to this pact.

That pact lasted precisely until about midnight of that very same day when Lolli slipped into my bed. I knew immediately, because I had been lying awake contemplating doing the exact same thing to her.

As we entwined our naked bodies and merged into another long kiss, I took a moment to remark to myself how pleased I was that she had not been lying about her pajamas.
