The nearly-worshipping touches trailing over his skin make Finn shake, pleasure ramping up so high so quickly that he's sure he's about to explode--to pull himself back somewhat, he leans down when Kurt's head falls back, and mouths over Kurt's neck, something to focus on. He nibbles lightly on the tendon, flicks his tongue into the dip just under his adam's apple. With the smaller boy's slim thighs falling open wider, Finn sinks deeper inside, and he groans thickly in the feeling, tilting his head up a bit to pant hotly against the skin just under Kurt's chin, breathing him.
His hands slide down his stepbrother's back, slipping low to grip the slender curve of his hips. It's all so good it almost hurts, but it's too slow, too little; Finn needs more, needs it desperately. Pulling Kurt's hips up against his own a bit, changing the angle, he starts thrusting a little quicker, bit by bit, gasping for air. (It actually sucks, Finn thinks, that this isn't the first time he'd done this sort of thing...this is everything he'd thought it should be, the way it hadn't come even close to feeling with Santana. Even...getting as far as he ever had with Rachel, it hadn't felt this intimate. And that's sort of terrifying. But amazing, at the same time.)
He keeps up that quicker rhythm, fingers tightening into Kurt's hips and rocking them together perfectly--vaguely, he's aware that he can feel Kurt's own erection pressing against his stomach, leaking profusely, and somehow that doesn't freak Finn out in the slightest. In fact, it just...turns him on more. To know that Kurt is this aroused because of him...it's feeding his own desire, pulling all the heat inside him higher and higher. "A-again," Finn gasps, nipping at the smaller boy's jawline, "C-call...call my name again."
Kurt whimpers at the hot, wet touch to his neck - the nips, that lick. His arms slide away to rest on the sheets, and he tilts his head a little to give Finn easier access. Another cry when suddenly Finn's length sinks deeper yet, hands shifting to grip the sheets tightly. He actually keens again when the angle is changed, each thrust now stimulating Kurt's sweet spot and making him see stars. The quicker pace steals his breath away again. He can't stop shivering, sparks of pleasure trailing up his spine before traveling over every inch of him, bringing back that restlessness to his limbs and making his skin feel over-sensitive.
There's something incredible about letting Finn do all the work, control the pace. It means Kurt doesn't have to do anything but feel - feel his stepbrother's thick cock pumping in and out of him, rubbing against all the sensitive spots inside him and that one in particular that's making him moan, high and shaky. In addition he can feel his own cock pressed against Finn's stomach, the pressure and slight friction cause by their movement making the length twitch, leaking pulses of precum as his pleasure climbs, as heat pools, thick and heavy, beneath his stomach. He can't help but pull at the sheets that are being tightly clutched between his fingers. That restlessness has slowly spread from his limbs to his hips, which he desperately wriggles and bucks, practically writhing and arching. He's anything but quiet during this - whimpering, panting, moaning shamelessly. These sounds transform into words, cried out at Finn's request. "Finn! Oh my god... Finn, d-don't stop! I love you! Oh! Oh, d-don't you.. don't you dare stop," he ends in a whimper. It's almost ridiculous how good this all feels. The thought briefly crosses his mind that he could easily become addicted to this, this heart-racing, tear-inducing, breath-stealing pleasure that makes him want to scream... At the same time though, he greatly suspects it wouldn't even be half as incredible, as intense with anyone but Finn.
The desperate words spilling from Kurt's lips, unlocked when Finn had told him to do so, are beyond pleasant--it makes it hard to keep control, to not grab hold of his stepbrother's legs and open him up wider yet, slam his hips so much faster, harder, claiming Kurt as his own with each thrust. But...he's sort of doing that anyway, with the tight grip on those slim-curved hips, every plunge of his cock into Kurt's body smooth and deep, his entire body thrown into the feeling.
He can't even begin to help the sounds he's releasing--low moans, heavy pants and whispers of expletives and Kurt's name--he'd been completely unprepared for the sheer onslaught of pleasure. He'd had no idea it could feel like this...and the thought does occur to him, at the same moment, that there's the very real danger of becoming addicted. It's possible he already is. And there's a certain amount of possessiveness to it--he doesn't want anyone else to see this side of Kurt, he wants it for himself, Kurt is his.
It's becoming almost too much, but Finn doesn't want this to end, not yet, not when everything feels this fucking good. In some attempt to hold on, he leans down, bodies tightly pressed together as he seeks out Kurt's mouth again--and not quite so gently this time; he flicks his tongue into the smaller boy's mouth right away, probes every inch of it, nipping lightly at those plush lips before going back for more. It's intense, devouring, as though he'd been holding back up until this moment and simply can't anymore.
Bringing his arms up and wrapping them tightly around Finn's neck, Kurt returns his kiss eagerly, wetly, whimpers and moans muffled by their busy mouths. He's already dangerously close to climax, his body still moving desperately, restlessly beneath Finn (as much as it can, anyway, what with it being so tightly pressed to Finn's own body). That almost possessive quality to Finn's actions isn't lost on Kurt - no, it's something he can read and understand even in his currently very distracted mind. And honestly that quality to it just makes everything that much hotter, that much more intense. The kiss, his smooth, deep thrusts, even the tight grip on his hips - it all attributes to that unspoken claim 'You're mine'. And Kurt can't deny it. It's true. He is Finn's, no matter what. He always has been, and probably always will be. And if that means that Finn will always continue to lay claim to him like this... Well, then Kurt certainly has no problem with that.
Okay, well, there is a teensy problem, one that honestly has yet to cross Kurt's mind because of his current state of distraction, but nevertheless it is there, waiting to pounce the moment his mind becomes still and clear enough for the thought to surface. Which is that their parents are married. Which wouldn't be a problem with Kurt except for the fact that they may not exactly approve of this relationship. Oh, and then there's also the fact that he's currently on good terms with Rachel and he highly doubts she'd be immediately thrilled upon finding out the ex-boyfriend she wants back is currently nailing his stepbrother to the mattress, and quite enthusiastically, too. Thankfully Kurt is still, for the most part, blissfully unaffected by these little complications. He is far too concerned, at this particular moment, in the said nailing that is currently in progress.
Similarly, Finn's mind is nowhere near anyone else right now; he's not considering what anyone might think, not their parents, not Rachel, no one. He's not thinking of anything at all, actually, outside of this particular moment...where this will go in the future, what all this possessiveness inside him means...it doesn't matter right now. All that matters is the two of them, the almost-unbearable heat of their bodies pressed together, the taste of Kurt's soft mouth against his tongue, and this incredible, impossible pleasure that's like a string pulled tight inside him, so, so close to snapping.
There's a moment, when Finn has to break the kiss in order to breathe, that his eyes open half-mast and his gaze catches Kurt's, and everything seems to suspend from reality, slowing down. Kurt is flushed and panting and wrapped tightly around him, wanting, desperate, adoring...and Finn can honestly not think of anything he's ever seen more beautiful than this.
Shaking slightly, Finn can't help but pick up his pace a little, thrusting quicker into the hot, tight clench of his stepbrother's body, and pushing down a bit in such a way that Kurt's own (probably insanely aching by now) cock gets a little more friction between their bodies. He pants brokenly against the smaller boy's lips, moans. "K-Kurt, I'm--I can't h-hold on--it's...mnn, you're so--so good--" he manages to gasp, clinging tighter; he's getting to the point of no return.
When their gazes meet, a thrill runs through Kurt's body, chased by goosebumps on his skin. He wraps his legs as best he can around Finn's waist, arms still encircling his stepbrother's neck. His noises get higher and higher pitched as Finn picks up his pace, the increased friction against his almost painfully neglected cock pulling a shaky moan from his lips. He tosses his head, drops his arms once again to the bedspread so he can clutch the sheets between his fingers. He can feel himself rising to his peak, his rapidly approaching climax preceded by increasingly desperate whines. "-too. M-me too... I-I'm g-going to.. G-going to..." And that's all the warning he manages to murmur out before orgasm takes hold of him, rips through him, his body arching and a high, throaty cry leaving him. He shudders tremendously, nearly pulls the sheets clean off as he comes, wracked by pleasure. He's at once both too hot and too cold, and his orgasm is so intense it pulls tears from his eyes, momentarily steals his breath and voice away. Strings of white decorate his belly and chest and, thanks to their being pressed so closely together, also Finn's. During his climax, the muscles in his body spasm, causing him, as a result, to tighten magnificently around Finn's cock. The pink tinge of his flush spreads far over his body, which is dotted with sweat even though Finn did most of the work, and his kiss-swollen lips remain parted as he tries to regain his breath. Overall, it's definitely the most amazing orgasm he's ever had.
'Magnificently' is selling it a little short; the sudden tightening-pulsing-throbbing around Finn's aching cock is so intense that he has no hope of holding on any longer--he'd wanted to watch Kurt longer in the midst of his climax. The way he'd thrown his head back, practically ripping the sheets right off the bed, it's so sexy Finn can't even wrap his brain around it...but then it's too much, the sensation racing to a sudden peak, and his head drops to Kurt's collarbone like he doesn't have the ability to hold anything else out any longer.
His orgasm hits him like a train, that dense knot of heat in the pit of his stomach erupting like a supernova. His arms suddenly lock around Kurt's waist, and a deep groan lingers in his throat as his thrusts become twice as slow and twice as hard, coaxing each pulse of his climax with the tightness of his stepbrother's body, spilling himself deep, deep inside the other boy. He's never come like this before, prolonged and so deeply, and the sounds he's making are nothing short of stunned.
When it finally tapers off, Finn shudders heavily and his strength all seems to leave his body at once. He practically collapses forward, panting so hard his lungs almost ache, head swimming pleasantly. Without even completely intending to, more acting on some tender feeling borne of his now-overwhelming sense of afterglow, Finn presses his lips softly to Kurt's shoulder.
The way it feels to have Finn release inside him is indescribable. It's the one thing Kurt's always been wary about regarding sex - he'd thought it would be gross. It's not. And Kurt probably wouldn't have the energy to be disgusted at it even if it was. Their coupling, not to mention his intense orgasm, has left him completely exhausted. He's never felt so spent, and satisfied, before. His eyes slip half shut, chest rising and falling as he slowly regains his breath. Arms come up to wrap around Finn's back, and Kurt can't help but press a soft kiss to his stepbrother's forehead. His afterglow leaves a sleepy, sated smile on his lightly flushed face. It's still a little too soon for reality to come flooding back completely - his mind, though certainly not distracted anymore, is just the opposite: too empty, void of any thought at all, or even the capacity for thought, at this particular moment. No, there's no thinking. Only feeling. And what he feels is a tremendous surge of warmth, of love. He feels the need to be wrapped up in Finn's arms this way for as long as he possibly can. He feels the need to listen to Finn breathing, to his heart beat. But when a thought finally does begin to surface in that former void of his mind, it's merely that he would be even more sated and happy if he could get cleaned up a little, as his essence rapidly cooling on his stomach is decidedly not attributing to the warm-and-fuzzy feelings of afterglow.
Finn can't even keep his eyes open at this point, too thoroughly sated--that had been a much stronger orgasm than he's at all used to {the usual being the result of a quick masturbation session in the shower or before going to bed, nothing terribly intimate), so the afterglow matches it. He's completely drained, leaning his weight mostly on his elbows and forearms, braced on either side of Kurt's body even as he's still pretty much lying right on top of him. The soft kiss against his forehead makes him smile softly, affection making the whole feeling deeper, filling some empty spot deep inside of him.
Thoughts haven't caught up to him yet, and reality is even further off. It's easy to forget where they are, who they are in relation to one another, all the reasons this might not have been the best idea, because at the moment Finn can't remember the last time he felt this content. The slowly-evening breath against his temple is marvelously soothing, and...hm, that wet feeling cooling on his abdomen is a little uncomfortable. Shifting with a soft groan, Finn presses another soft kiss to Kurt's skin, this time on the underside of his jaw, and he murmurs, "One sec." With effort, he lifts his head and moves a little, carefully slipping himself out of the smaller boy's body while looking for something he could use to...
...ah, tissues, that would work. A bit clumsily, Finn grabs a handful of them from the nightstand and flops down next to his stepbrother, actually flushing a little again as he carefully wipes the seed from Kurt's skin...there's kind of a lot. God, Kurt had come hard, hadn't he? (Not that Finn's had been any less intense.) He finishes wiping it up, first from Kurt then himself, before tossing them onto the nightstand out of lack of other places to throw them (the trashcan is by the desk, and the idea of getting up to get to it is not so awesome at the moment). Feeling both oddly sheepish and deeply in need of more of that soft affection, Finn lays back down again, wraps his arms gently around Kurt's lithe frame.
Kurt's eyes slip shut as he feels Finn start to move, the contented noise he makes when Finn presses that soft kiss against his jaw shifting into a whimper when he then withdraws from Kurt's body. The smaller boy shifts lazily, moving the covers a bit with his legs. He breathes a "Thanks" as Finn cleans him off, his own flush deepening a little from how intimate that feels. Eyes flutter back open the moment his stepbrother lays back down, wraps his arms around him, and Kurt rests his head against the larger teen's shoulder, hand pressed to the broad chest, right above Finn's heart. He murmurs a "Blankets," which is basically all he can manage in his contented exhaustion, so he hopes the single word is good enough to convey the message. Though Finn's body is warm against his own, not quite enough to stave off the cold completely - it's always cold in the school and the dorms (Kurt suspects it's on purpose to make sure the boys don't repeatedly shuck off their blazers), although Kurt hadn't noticed it in the slightest during... The sweat cooling on his skin now, though, is making him shiver in his stepbrother's arms.
Blankets...right, that's a good idea. Finn's starting to feel a little cold too, even with the warm body against his own, warm hand on his chest, warm breath on his shoulder, sedating...right, he should move before he falls asleep or something. Nodding a little, he pushes himself up only as much as he needs to, grabbing the edge of the blankets that had been tossed back (and he catches sight of how barely the fitted sheet under them is hanging on in lieu of Kurt yanking so much at it, which makes a lopsided grin tilt his lips) and pulls them up over the two of them.
He lies back down again, sighing softly like that had taken it all out of him, and returns his arms to their place around Kurt's body. It's...almost strange, he thinks, how well they fit together like this. Finn tilts his head down a little, closes his eyes, as he presses a kiss into Kurt's soft hair and then stays there for a long moment, just breathing the faintly sweet scent of the smaller boy's shampoo. He could...stay like this for a very long time, really.
Finn's eyes flutter shut, but he does his best not to drift off for now. This is too awesome to sleep through...this tenderness he's never felt before. And he's sort of adamantly staving off any thoughts of 'what comes next', because...oh, that's such a big question right now; everything is up in the air now, and what it all means is...it's important. It needs to be thought about, and deeply. But...it can wait. For now.
