The Island: A Sibling Rivalry Tale

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.
