Nokini Atoll Pt 02

Kyle got up from the dinner table first. "Hey, chill out, I got the dishes tonight."

He knew it'd be good to keep his hands busy, and give himself something to focus on other than his sister sitting naked across the table from him. They were still in "detox mode" after going a little too far together, and Kyle's balls objected, despite how often he emptied them into the bathroom sink. What he'd felt with Claire was more intense than anything he'd ever experienced before, and it was hard to suddenly put all that aside.

"You washed the dishes every night for the past week," Claire said, and he was surprised to hear a note of complaint in her voice. "Sit down for a sec. I want to talk."

He joined her at the table again, putting his hand out towards the middle between them, where she could take it if she wanted to.

"I know what all this is about, Kyle," she said.

"What do you mean?"

"Well, ever since we...you know...stopped. You've been extra nice to me."

"Why shouldn't I be nice--?" he started to ask.

"Let me guess. Being nice to girls has been a somewhat successful strategy for showing girls that you're attracted to them and convincing them to sleep with you."

"Claire. It's not. It's not that," he stammered, his face growing hot. "I wouldn't. I just. I wanted to."

"I get it," she said, ignoring his protests. "But...it can't work that way with us. You know it can't, right?"

"But...it's been what, thirty-five days since that last time, and we've done it. We've detoxed, right? We've proven that, even if we went down that path a little, we can still come back from it," he said. This wasn't how he wanted to end up making this case to her, but she had backed him into a corner.

"Kyle, you're making it really clear to me just how not over it you still are." She rubbed a hand over her face. "It's not easy for me either. And you're not making it any easier. But I need you to just assume that nothing like that is ever going to happen again. I need you to be the sane one when I'm the one faltering, because...otherwise we're not going to make it a year here. And worse than that, it's going to hang over us for the rest of our lives."

Kyle slumped in his chair. "I get that. I know we have to be careful. I just don't see why 'careful' has to mean nothing at all."

"You're saying a blowjob would do it for you?" Claire asked with a smirk.

Kyle spared a glance at her naked body. All the places he longed to touch. Imagined them conjoined, writhing together. He was firming up under the table, not at all subtle, since it was a glass table.

"Yeah. Absolutely," he said.

There was a long pause; she seemed to be seriously considering it. "No. I can't. We can't," she said. "I shouldn't have mentioned that. Besides, this isn't a negotiation. I need you on my side."

"I'm always on your side," he said, and he meant it.

Maybe it hadn't always been true, but it was how he felt now. Even if she didn't want to do anything physical--sexual--with him, he still wanted to be there for her. This wasn't some no-strings-attached hookup for him.

***

It was a couple weeks after that. When the sun was at its burning height, and the sand was hot, they took a siesta in the cottage. Today they were playing cards at the table. The cottage was air-conditioned, but it was struggling to keep up today. They would have been miserable if they weren't already nude.

Claire had her legs crossed, bouncing one heel, keeping her arousal on edge. It didn't help that Kyle was erect, as he so often was, his shaft clearly visible under the clear glass table, pretty much pointed at her, leaking precum. She had her desires largely quashed, but she still had challenging moments like this. Realizing she was getting herself worked up, she uncrossed her legs, and tried to sit still.

Kyle was looking at the fan of cards in his hand, or that's what it looked like he was doing.

"You're...uh...bleeding a little," he said.

She looked down and saw what he was referring to, a thin line of red between her lips.

"You never encountered this with any of your girlfriends?" she asked.

His eyes shifted to the side. "I've never really had...that kind of thing with anyone."

"What do you mean?"

"There was Sandra first. We were dating, kinda, but for most of the time we were together, it was completely chaste. And then eventually, once we were both eighteen, we had sex, and it was a whole production, with her mom making sure she was prepared and okay and everything. We tried it a few times, but she just wasn't that into it. Which is fine. And I get that it's not about me..."

Claire was quietly impressed that her little brother had the emotional depth to accept that. But the way he had acted with her had mostly been like that too.

"...and since then, I've only had a couple one-time things. There was Mary, one of my best friends throughout high school. And then we graduate and we're about to go off to different colleges, and she confesses she's had a crush on me since freshman year. So we ended up having sex once, but that was it. It was so hard to hook up at all, living at Uncle Toby's. The only other time was with someone named Emily, at a friend's party."

"Huh," Claire said. It seemed like Kyle had only ever just fooled around with whoever was willing. She wondered if he had ever been in love. But she didn't ask, worrying what his answer might be.

"Well, as long as you don't faint at the sight of blood, you should be okay," she said. "It's just a thing that happens, on a monthly basis."

"Does it hurt?" he asked.

"No, not really. It used to hurt worse, and then I went on the pill. And then since I've been off the pill again, it's come back just a little." She took some private amusement at seeing his cock throb as she talked about going on and off the pill.

"What about you?" he asked. "What have your relationships been like?"

She couldn't tell if he was trying to be a good friend, or looking for more wank material. And the question brought back memories of Greg, which she really didn't want to get into.

"I've been with five men before. Well, six. But outside these walls, it's still five," she gave him a wink. "There were a couple brief flings. One older guy who really shouldn't have been messing around with a high school senior. One guy it took me several tries to quit. And one guy where I thought we had it locked in, and he was still shopping around."

"What an idiot," Kyle said.

"That's a bit harsh," Claire said, thinking he was judging her dodgy dating history.

"He should have realized what he had," Kyle said, not meeting her eye.

"Anyway, it's your turn," she reminded him. "Whenever you're ready to finish losing this game."

She got up to wipe away the blood, but there really wasn't a lot. More of a thin red streak mixed into the evidence of her near-constant state of arousal. Kyle must have really been looking close to notice; it couldn't have escaped him how turned on she was around him. It was a little embarrassing for her; she was glad he wasn't pressing that point.

That night, Claire lay her head on the pillow, her eyes open to the dim wash of moonlight that filtered into the cottage. In the couple weeks since she'd given Kyle a stern talk, he hadn't pushed her. He hadn't propositioned her, or anything remotely leading in that direction, though it was obvious how much of the time they both spent aroused out of their minds. Maybe they were "detoxed". Maybe crossing the line once didn't mean they were messed up for life. The thought felt dangerous; it made her heart beat faster.

She felt his back against hers. They were being more careful now. No more spooning. No more kisses on the back of her neck. No more slipping into her in the early morning. She missed his embrace though. Maybe that contact had been tiding her over, in a way nothing else was.

They had made it six months here without committing incest. Even when it meant sharing a bed, and being nude in front of each other. That should have meant that they could get through the second half of the year with no problem.

But then they lost that control. They crossed the line that mattered, even if the sex they'd had wasn't the way most people did it. Claire kept thinking back to that night she took him inside her, how her body came alive with the sensation of it. With the forbidden knowledge of what it meant.

Claire felt feverish with that desire that wouldn't leave her. This desire had been with her so long, that it never really went away anymore, like a constant hum. She only ever noticed the peaks of it, when it became nearly overwhelming. It was so bad it gave her headaches, made her hands shake, left her parched. She tried to hide it, but it was a lot to endure.

She rolled towards Kyle, her erect nipples pressing against his back.

"Are you still awake?" she asked softly, though there was no one else around to hear. Her hand slipped around his waist, in something that could have been an innocent embrace.

He answered her by stroking her arm with his hand. She let her hand travel further into his lap, found him rigid there. Already hot and sticky at the tip.

"Am I supposed to be your self-control right now?" he asked. "Because I don't want to be, but I can, if it's what you need."

"That's not what I need," she said, brazenly stroking him now, feeling the pleasure settle into his whole body with her every movement, her every tease and promise.

She went on, "Since I'm on my period...let's just consider this a one-time jubilee."

"Like a carnival?" he asked.

"Right. For the next three days, anything goes," she said, and felt his cock pulse in response. Three days was a bit arbitrary, but it felt about right somehow, for a temporary suspension of the rules between them.

Claire got up on her knees, and rolled him onto his back. She straddled his waist, and held the tip of him to where she needed him most. Lowering herself down on him, she felt him slide up into her. She was so well lubricated that it was all too easy, but all too sweet too. In that moment, she knew she was discarding all the normalcy they'd painstakingly clawed back, but she was ready to give it all up, for this.

She moaned as he pressed into her. His hands went to her hips, his grip almost painfully tight. When her weight fully rested on him, his cock about as far up into her as it could reach, she sat there for a breath, feeling herself adjust to him. Feeling him feeling her adjust to him. It helped that she knew him so well, knew his naked body in more detail than a sister ever should, and could clearly read his reactions in every labored rise and fall of his chest, every subtle shift of him inside her. She felt so sensitive that every little movement between them was a broadcast in her mind.

They'd been here before, conjoined but unmoving. She could just finger herself to orgasm with him inside her. She could bring him to orgasm in the process. That would be territory they'd trodden before. Safe, or no less safe than before at least. She knew this, but she wanted something new, to make this transgression worth it.

She started to rise and fall, her hips finding a rhythm atop his, until he was pushing off the mattress, thrusting up into her in time, unlocking new pleasures inside her. His hands moved to her breasts; she felt his caress adoring them, exploring them, gentle and teasing and patient.

She didn't expect this to last long, didn't expect it to take this long, her arousal already at such a high, unsustainable plateau to start with.

Then he suddenly gasped in a high pitch, "Oh fuck!" This could have given her a moment's warning to pull away if she didn't want what she knew was coming. Instead she pushed herself down on him as hard as she could, taking him deep into herself. She felt him swell inside her, and consciously answered it with a contraction of her vaginal muscles.

His seed shot up into her recesses. She felt the pressure of it, and the warmth of it spreading through her. She collapsed forward onto his chest, unable to support or balance herself, as her orgasm overpowered her. She felt herself squeezing down on him hard, harder than she consciously knew how to. She felt him swell up inside her again, and give her more. There were sounds coming from her mouth, but they were outside her control. His arms cradled her tight, as this process rocked them both.

Seismic earthquakes ran through Claire's core, and a white hot pleasure that threatened to blot out her consciousness. Eventually Kyle was spent, his cock gradually spasming weaker and weaker, adding less and less to the voluminous well inside her.

Afterwards, she expected to feel disgusted and ill at ease with what she'd just done--taking her brother's seed deep inside herself--but instead she felt euphoric and relaxed. It was like she'd finally released a tension that she'd been unconsciously carrying for longer than she could remember.

In fact, she couldn't remember ever experiencing an orgasm quite like that before. She'd known what it felt like to have a man ejaculate inside her, and had taken pleasure in it plenty of times. The sensation of it, and the knowledge of what it meant--it was literal fluid evidence of the ecstasy she induced in her partners. But this time, it was something more. Something an order of magnitude more powerful.

"I've wanted to do that for months," Kyle said softly, still out of breath.

"I know," she said. "It felt like you were saving up. Though we both know that isn't true."

For one, she'd brought him to orgasm just a month ago. For another, she knew he jacked off that morning.

"This is top secret, but guys have an extra reservoir that only opens up when they're ejaculating in a woman's vagina," he said.

"Gross," she teased, mostly in reaction to his clinical choice of words.

"Okay, that's not true either," Kyle said. "This wasn't the first time I've...done it bareback, but I've never experienced anything remotely like that before."

"Maybe because you've never been with a grown woman," she joked, and felt him hardening back up inside her, making her gasp. "How are you doing that again so soon?"

"What, you don't remember what it was like to be eighteen?" he joked.

She started moving her hips again, and was rewarded by his soft moans beneath her. Their union was hot and sticky already with his semen, sliding easily against each other.

This time he lasted long enough that she climaxed first, losing her rhythm as her instincts muscled into the driver's seat, her vaginal walls squeezing down on him almost painfully hard, drenching his crotch with the overflow of his previous deposit. He was soon to follow, pushing up into her with all his strength, as if searching for some untouched part of her to explore, to conquer and make his own.

And then somehow he came inside her again, not as much as before, but a surprising amount, considering. The sudden rush of it, the renewed heat, sent her climax into the stratosphere, to the very edge of consciousness. On one hand, it felt natural and right and like what she was built for. On the other hand, her body had limits, and she was pushing them. It felt like the white-hot pleasure was rewiring her brain in real time, as much as any narcotic.

They took the time to shower before settling back down again to sleep, washing off their combined fluids, though Claire knew a lot of it was still inside her. It was reassuring, in a way, to see a streak of her blood on Kyle's cock, reminding her that this was the safe time to indulge this impulse. Otherwise, with that much of his sperm exploring her uterus, she was sure to end up pregnant.

Back in their bed, Claire felt sleep drawing her under as soon as she laid down, but it helped to feel Kyle curled around her, warm against her back, no longer keeping a careful distance.

***

Kyle woke up still spooned against his sister's back, cozy and warm, to the sight of her sex-tousled hair. It was hard to believe they'd gone so far last night. And she'd said three days of this. He was going to make the most of it while it lasted.

He breathed her in. The scent of sex, a little iron of blood, a little salt of the sea, and something familiar that had always been her. Her sweat, maybe.

He brushed a bit of her hair aside and kissed the back of her neck, feeling the shiver travel down her spine to where he was already hard again and pressed almost painfully against her. But after everything they'd gotten up to the night before, that gap between her thighs was well-lubricated. Maybe it was her arousal, or more of him leaking out between her legs.

He slid easily between her thighs from behind, and when she angled her hips down, and her butt up against him, he felt the tip of his cock nudge just inside her, the way he had once before, months ago. Except this time he gripped her hip and pushed forward to meet her, pushing himself deeper into her. It sent a ripple of pleasure throughout her body, all the way down to her toes curling against his leg.

He paused there, letting her awaken a little, letting her object, if she wanted to. There was still a chance she'd regret their transgressions in the daylight. Maybe that thing about "three days" had been an empty promise made in the throes of passion. He felt her vaginal muscles tensing around him, waking up, measuring up the intruder, or maybe egging him on. When she pushed her whole body back at him, that made her intentions clear. He might've been content to take his time, but she was driven.

They rutted like that for a good while, until Kyle felt sweat beading on his skin. But he could only get so deep in this position. He could feel her organ tugging on him, squeezing down on a shaft that hadn't quite been driven all the way into her yet.

Her desperation was palpable as she drew away from him, only to roll towards him and put one leg up over his hip, drawing them into contact again. He slipped back into her, and now he could push that much deeper, making them both gasp and groan. His arms wrapped around her torso, and she clutched his back with all her strength, their muscles straining to bring their bodies into more complete contact. He could feel her tensing up inside, and recognized it by now as the precipice of her climax.

With a strangled cry, he pressed hard into her, burying himself as deep as he could go, until there was no length of himself between them. His breath stopped as his shaft pulsed inside her, and then he let go and filled her again.

Her reaction was a sigh or a sob, high and plaintive. But it wasn't only his ears that told him she felt his release, and that it brought on her own. He could feel her squeezing down on him, drawing his semen out of him like poison. Her chest heaved with every contraction, her shaky, hot breath against his ear, as every interior inch of her caressed every surface of him, the stimulation so overwhelming it was almost agony.

Kyle was in awe. Over their several months together, he had come to see how beautiful she was, curves and all. But the more they did together, the more he was blown away with her relentless sex drive, and the athletic musculature that made it seemingly effortless to match his every move. He marveled at the incredible pleasure her body was clearly capable of, and the pleasure she was able to draw out of him.

He'd never been with anyone remotely like this before, and it was a perverse twist of fate that it would be his sister. The same person he'd grown up with. He was in awe of her even before last night, but now she was special to him in a whole new way. For Kyle, the experience already felt life-changing, and not just for the way it might forever redefine their sibling relationship.

As they came down from their shared bliss, Kyle indulged himself by feeling the curve of her hip and the soft skin there, feeling her breast, the heft and fullness and softness of it, running a thumb gently over her nipple, tracing the curve of her neck down to her shoulder. Had she always been like this? Could he have truly been so oblivious?
