He's Mine

Pairing: Nagisa/Rei

A/N: Wow, I deserve a brick to the face for this super late chapter. But there's an intimate scene and it's now rated M! To be honest, I don't think it fits in the M category since the 'action' is fairly mild, but it's barely there. If only there's a borderline T/M category...

Disclaimer: This is a fan fiction of Free!, a fantastic anime with interesting plot, ifyouknowwhatimean.

A lot of things happened in a span of a day, and despite being highly intellectual, Rei couldn't quite comprehend everything just yet. He had encountered a life-threatening experience in the pool, seen Nagisa cry for the first time, confessed his secret love for Nagisa (after being in denial for so long) and finally gotten himself a lover. It hadn't been such a bad day; in fact, Rei had been engulfed in a warm cocoon of contentment now that he knew that his feelings were reciprocated.

Well, that was until Nagisa mentioned that he wanted to sleep over.

It was not that Rei hated having Nagisa over, and he's not worried about his family's reaction toward Nagisa's sudden appearance in their house either. In any case, they seemed to be accepting Nagisa very well and enjoyed his company, judging from the way they treated him kindly the last few times. Heck, sometimes Rei even wondered if his mother loved Nagisa more than she loved her own son, what with all the affection she lavishly showered him with!

But there was just something that made this time different.

They're lovers now, and lovers do things when they're alone, things Rei had absolutely zero experience in.

Presently, Ryugazaki Rei wished that the steady ground would just open up and swallow him whole.

He watched warily from the side as the golden haired boy skipped around in his room, marveling at the impressive collection of trophies and medals Rei had received back when he was still active in track and field events. Despite having seen the collection for a few times already, somehow it never ceased to amaze Nagisa.

"Everything about Rei-chan is soooo cool and impressive!" was what Nagisa had told him once, and Rei had responded with a blush and a pathetically stuttered "I-it's nothing, I just followed theories and c-calculations...", which was essentially the truth. His steps were always based on meticulous and intricate formulae, and Rei would never be satisfied until he got it right.

Nagisa was the sole person who had told Rei that he's beautiful, beautiful the way he is -no figures, no calculations, no theories- and Rei's thankful for that (though he had troubles expressing it).

Presumably slightly worn out from all the ruckus he was making, Nagisa plopped on the bed face down and hugged one of the black pillows close to his chest, burying his face into it fondly. Rei immediately felt his face heat up upon realizing that Nagisa had picked up the one he had accidentally humped when he was having the wet dream.

Coughing loudly to distract himself from the embarrassing thought, Rei cleared his throat to attract Nagisa's attention.

"Err, Nagisa-kun?"

"Mmhh..."

Nagisa stopped nuzzling the pillow and turned around to look at Rei. In the process, his pajama shirt (Rei's, actually, as always Nagisa almost never brought his with him) rode up his abdomen, exposing the milky alabaster skin teasingly. Rei could see the vividly displayed contours and outlines of Nagisa's pectoral muscles, as well as a tiny hint of dusky caramel patch of skin peeking out from underneath the clothes that Rei's perverted mind imagined to be Nagisa's nipple. Rei cursed under his breath; that sight was undoubtedly not good for his young vulnerable heart.

"Uh, do you want me to get us some drinks? Barley tea, maybe?"

"Oh Rei-chan… You and your barley tea!" Nagisa snorted and sat upright on the bed, shaking his head to signal his disapproval. "Nah, I'm not thirsty," he said with a smile. Noticing how much of a nervous wreck Rei was becoming at the time, he wanted to see how Rei handled the awkward ambiance.

"Then, what would you like to do? We can play games if you want to... But I have nothing other than chess and scrabbles, so don't expect too much."

Gaming was Nagisa's forte; it was one of the few things he could excel better than Rei besides swimming, but chess and scrabbles were hardly 'games' when classified according to Nagisa's standards. The last time they had a chess battle, Rei pulled the 3-steps checkmate trick on him and Nagisa vowed to never touch the checkered board again.

"It's okay, we can play another game, Rei-chan!"

With that, the jubilant boy stood up and ran toward Rei, grabbing his hand and tugging on it harshly. Both of them fell unceremoniously onto the cramped single bed in a jumbled mess of tangled limbs, and Nagisa's infectious laughter slowly faded out when he rolled them over. He climbed on top of Rei's stiff body, placing his bottom directly on Rei's thighs.

Nagisa was radiating comforting heat from the points where their bodies touched, and the room became eerily silent now that he'd stopped laughing.

Feeling anxious and intimidated under Nagisa's suddenly serious expression, Rei fiddled with his glasses and darted his eyes away, avoiding the intense gaze.

"W-what kind of... game is this, Nagisa-kun?"

Nagisa remained silent. His predatory eyes did not waver; instead they now sparkled almost cat-like. He's planning something, Rei could sense it. True enough, Nagisa leaned down in a painfully slow pace, shortening the distance between them and Rei could only think 'Oh god he's going to kiss me again what is the correct angle should I lean to the left or right I can't screw this up-'

Rei already had his eyes closed when out of the blue, rapid tickles attacked his sensitive sides. Things went downhill from there as Nagisa's nimble fingers left fleeting touches everywhere; the area just beneath his ribs, under his armpits and around his collarbones. Rei squirmed underneath the assaults and broke into an inevitable fit of giggles.

"We're playing the tickle game, Rei-chan! It's fun!" Nagisa squealed, the usual bright grin returning to his face as he continued tickling Rei. For some reason, Rei seemed to be ticklish all over, like his whole body was a huge blob of sensitive points, and the sadistic part of Nagisa enjoyed watching Rei writhing beneath him, helplessly trying to get away from his naughty hands.

Not to mention that Rei's laugh was mellifluous music to his ears.

"Don't- Na-nagi- sa!" Rei's protests came out in breathless pants. Tears prickled his eyes, and some were already leaking out and trailing down his cheeks. His face was flushed from laughing too much and his body had melted into a puddle of goo, but putting physics into practice, he managed to use the last few ounces of his strength to manipulate his weight and inertia, turning them over so that Nagisa was pinned beneath him.

'Ahh, revenge is sweet. I knew that inertia would come in handy someday,' Rei thought when he successfully caught Nagisa's wrists and held them down.

Nagisa struggled to break free from Rei's vice grips but to no avail; once Rei had made up his mind, his determination would not be shaken. Now that Rei was on top, gravity pulled his already loose red glasses downwards, leaving it crooked and hanging ridiculously off the bridge of his nose. He looked funny, but Nagisa had to stifle his oncoming laugh for fear of an angry Rei.

"Rei-chan, I was just kidding 'kay?" Nagisa grinned toothily, feigning innocence. "Let's play scrabbles!"

"Hmm..." Rei went silent, as if he was reconsidering his actions. The Rei prior to meeting Nagisa would have scowled angrily and furiously stalked off, unwilling to participate in such time-consuming and preposterous activity like tickling, but the current Rei was already exposed to the joys of fooling around, and Rei would be lying if he claimed that he wasn't curious to find out if Nagisa was ticklish.

'Two can play this game...' Rei thought to himself and smiled darkly. The corners of his mouth twitching upwards contradicted his menacing stare, and it sent icy shivers down Nagisa's spine.

"But Nagisa-kun, I'm thinking of returning the favour..."

Upon hearing the playful threat laced in Rei's words, Nagisa slowly backed away from Rei's looming presence, dragging along the black bed sheet underneath him as he moved. He only managed to move a mere few inches before his head hit the headboard.

He was trapped.

There was no turning back now. After all, he was the one who started the game in the first place.

"W-we can talk this through, Rei-chan… We ca- Ahhh!" Nagisa's scream was followed by cheerful laughter -much louder and less reserved than Rei's- as soon as Rei's fingers started attacking his waist. Considering the strident noises they were making, Rei was initially quite surprised that his parents had not knocked on his door to ask them to keep it low. But then, he recalled that his parents had left that evening to visit his older brother in the city.

This meant that they were alone with the whole house to themselves.

Nagisa and him.

Alone.

The mere thought of it drove Rei's composed mind wild with all the possibilities the situation held.

The tickles intensified, with Rei's large hands roaming freely all over Nagisa's trashing body, even reaching up to leave soft feathery touches on the sensitive skin just behind Nagisa's reddening ears.

"Ahaha- st-stop it Rei-chan! N-Not there!"

Nagisa squirmed and thrashed around, throwing his head back in reflex, his contagious laughter never ceasing. In the heat of the moment, he accidentally let out a moan; a sexy sound that shot straight to Rei's heart and unfortunately, the area between his legs.

Rei halted.

Ryugazaki Rei was usually extremely proud of his seemingly resolute self-restraint, but like other regular humans, he had his weakness, his kryptonite. Right now, feeling the inexplicable warmth enveloping his person and the way his heart leaped to his throat, Rei's dead sure his weakness was Nagisa.

Nagisa's cackles began to die down when he noticed that Rei had stopped the tickles, opting to stare with glazed half-lidded eyes. Their faces were close; close enough for Nagisa to notice the love, the adoration, the desire embedded in those amethyst orbs.

At the moment, Rei was Nagisa's center of gravity, much like Nagisa was Rei's. Both of them were drawn towards each other, both unconsciously leaning forward, closer… and closer…

Until their lips touched.

Sparks ignited when they shared their second kiss, and they stayed that way, both savouring the moment, wanting to permanently burn the sensation into their minds. It was merely a sweet, innocent peck on the lips –or rather, on the corner of their lips, because Rei had actually miscalculated and barely missed it- but Rei swore he could hear freaking fireworks exploding in his head. Rei pulled away first, probably out of hesitation or fear of what was to come had the kiss continued, but Nagisa wouldn't have any of that.

And so he placed his hands on Rei's head, pulling him closer and smashing their lips together in an almost violent manner.

Nagisa actions thus far –the sleepover, the tickling, the seductive smiles- were all done under the perverse intention of making it to the first base (French kissing) at the very least. Nagisa could already guess that Rei had lesser experience in a relationship, and the fact that Rei seemed awkward with this made him kind of happy.

Gently, Nagisa ran his tongue along Rei's moist bottom lip, coaxing it to open and allow entrance. When Rei did not respond accordingly, Nagisa nibbled lightly, making Rei gasp, undoubtedly surprised by the bold feat. Like a hawk swooping down to grab its prey, Nagisa wasted no time in exploring Rei's mouth, his hands now buried in silky cobalt locks and clutching onto them for dear life.

If Rei were to describe how the deep kiss felt, he would run out of adjectives and be forced to make up his own new words. It was certainly mind-blowing and oddly arousing; a feeling so foreign to him. Nagisa's tongue was unbelievably skilled in dancing around his own, and although French kissing was a completely new subject to him (he didn't have the time to read or do some research on it yet, and was probably too ashamed to do so), playing along felt so natural.

The kiss intensified when Nagisa started sucking on Rei's tongue, the obscene slurping and sounds of lips smacking filling the room. To be honest, it wasn't in Nagisa's agenda to let things progress at such a rapid rate. He had thought of taking it slow, really, but being around Rei-chan just made his heart beat like mad, butterflies churn in his stomach and his love struck mind float on cloud nine. Besides, Rei-chan was reacting positively to his advances, so what's there to lose?

Nagisa let out a cute little whimper when Rei's hand slipped under his pajama shirt; the area where skin met skin feverish and the sensations electrifying. Rei didn't know where the greed came from, but suddenly, he wanted to hear more of those small noises Nagisa was making; craved to see more of the lusty expressions, just… he wanted to feel more. He followed his instincts and desire –something he never knew he was capable of until Nagisa came into the picture- and let his hands and lips greet Nagisa's soft skin.

Nagisa was beautiful, oh so beautiful and perfect and Rei felt his sanity slowly slipping away with each gasp and moan, each movement and contortion of Nagisa's face that clearly spelled bliss and pleasure.

It was only when Nagisa pressed his small palm against the bulge in his pants did Rei finally snapped out of his desire driven state. The touch had sent him jolting up most ungracefully, hands stopping their quest on uncharted territories (in other words, Nagisa's nipples).

'What am I doing? I'm not even ready for this!'

"I-I-I'm sorry, I shouldn't have done that." Stuttering a panicked apology, Rei retracted his hands from Nagisa's chest like he had just touched a scalding hot item, quickly removing himself from Nagisa's embrace and fumbling to make his way off the bed. Without his fallen glasses, even such a simple task turned troublesome.

"Why are you stopping, Rei-chan? You don't want this?" Nagisa asked, staring at Rei's retreating form with half-lidded lustful eyes that were now filled with confusion, bewilderment and a hint of hurt. 'Does Rei-chan prefer girls? Does he think I'm disgusting?'

"No!" Rei retaliated immediately, reclaiming his seat on the bed and letting his hand grasp Nagisa's smaller ones in a gesture of assurance. There was less awkwardness in their hand-holding now that they're doing it more often, and when Nagisa's sugar-coated smile returned, Rei felt a pang in his heart. He had to clear this up lest Nagisa misunderstands.

"No, that's not it. Of course I do, but…" Rei trailed off, unable to utter the real reason behind his reluctance.

"Let me guess, insufficient research?" Nagisa said, cheeky grin suggesting that he's joking. Surely it couldn't be such a trivial thing, right?

Rei bit his lip in embarrassment, the spreading blush reaching the tip of his ears giving the answer away. Bull's eye.

"Rei-chan, seriously?!" Nagisa exclaimed loudly, amusement clear in his tone. "You planned to read up on sex?" He shook his head in disbelief, giggles threatening to spill from his tightly pursed lips. He tried hard not to laugh, but lost the battle in mere seconds.

"Don't make fun of me, Nagisa-kun! It's just that…" Taking in a deep breath, Rei continued, hands tightening their grip on Nagisa's. "Look, I want our first time to be perfect, okay? No complications, no mistakes, just impeccable, immaculate and passionate copulation that ultimately results in pleasure and heightened levels of endorphin, and then... "

Rei's imagery of a perfect first time went on and on, and at least half of the technical jargon coming from Rei's mouth sounded like a Chemistry teacher's babble to him –incomprehensible, complex and boring- but Nagisa had to admit that intelligence was part of Rei's appeal.

Still, using 'copulation' to refer to sex might be going a little overboard.

"Oh, stop being so idealistic, Rei-chan, relax a little!" Nagisa chimed, pinching Rei's cheeks endearingly before leaning forward to rest his forehead on Rei's. The gesture worked wonders as Rei began to unwind under his touch. "It's not like I have more experience in this than you do. We're still learning, it'll get better with practice. Let's follow the flow, hm?"

For once, the things Nagisa was spouting actually made sense. Rei sighed deeply, closing his eyes to focus on the warmth seeping from his forehead and the gentle, loving way Nagisa was stroking his hair. "I just don't want you to be in pain, Nagisa-kun…"

"Awww, that's so sweet of you…" Nagisa beamed, kissing the tip of Rei's nose affectionately. However, the joy was short-lived when he replayed the sentence in his head, only to wound up feeling confused. "Wait... Pain? But Rei-chan, aren't you the one who will feel the pain?"

This time, it was the genius' turn to be puzzled. "Why me?"

"You know, I'll be entering you and stuff, so naturally Rei-chan is the one who'll feel it, right?"

Had Rei been drinking water at that moment, he would have spit it out, sending disgusting sprays of water onto Nagisa's face in a state of shock. Nagisa's lucky this time, because Rei's only responses were a choking sound and horrific widening of violet eyes.

"B-b-but I thought I will be penetrat—I mean, entering you!" Rei retorted, hands grabbing Nagisa's shoulders like he's struggling to find something, anything, that could anchor him to this world.

"Silly Rei-chan, you're the more beautiful one, so you're the bottom!"

"No, Nagisa-kun, you are definitely cuter and significantly shorter than me, so you'll be on the receiving end!"

The bickering went back and forth (as did the subconsciously uttered compliments that went unheeded) with neither wanting to back down and succumb to submission. It never occurred to Rei that Nagisa –petite, ridiculously adorable, innocent little Nagisa- would ever conjure the thoughts of dominating him, who was at least a good 5 inches taller and 20 pounds heavier, and when his mind started playing games with him by flashing images of a sexy smirking Nagisa straddling him suggestively, Rei for once hated his own blessed brain.

Was Nagisa ever innocent, anyway?

"Rei-chan," Nagisa suddenly interrupted their bantering session, effectively silencing Rei as well. "We'll settle this later… Right now," There was a pause, and then a mischievous smile; an added dramatic effect that send Rei's poor heart spiraling down a staircase of suspense, "we can just do this."

Rei gasped brightly, breath hitching in his throat, heartbeat increasing tenfold and having all the various bodily responses appropriate for when someone re-enters a state of arousal (mixed with fear and uncertainty) when he felt a sneaky hand slipping underneath his pajama pants' waistband and into his briefs.

And then he felt a squeeze.

"Nagisa-kun, please tell me you did not just do what I think you're doing."

"Hm?" An innocent smile appeared, followed by a long slow stroke and another squeeze that had Rei stifling a moan. "Do what, Rei-chan?"

"You did not just grab my hard-on." was what Rei had planned on saying, but he knew fairly well that Nagisa was doing just that, maybe even more because right then Nagisa's sinful fingers started making its way down, down, down to the base and fuck, that felt good. Incredible, even.

"Ahh, Rei-chan… Yours is so wet already!" The way Nagisa said it was downright disturbing, like he's talking about lollipops or strawberry ice-cream and not Rei's manhood, with his eyes dazzling and twinkling and his luscious lips curving up into a smug and satisfied smirk, much like a child getting his favourite popsicle.

In this context, the popsicle that Nagisa's getting and holding onto was… well, it was Rei's.

'Organic taste, eh?'

The thoughts echoed like a nightmare in Rei's mind; the embarrassment was enough to make him want to crawl under the bed and disappear. Just when he thought things couldn't be worse than having his classmate grabbing his dick like it's the most normal thing in the world, Nagisa yelled "Oh, it's twitching in my hand!"

"Stop that! Don't say it like it's nothing!" Rei croaked out, burying his feverish face in his hands to hide his mortification.

"It's fine~ Hey... Let your voice out, Rei-chan…"

Rei was about to protest again when he noticed Nagisa's heavy breathing and the occasional gasps that escaped his mouth. Entranced by the golden-haired boy's spell (Rei's 88% sure that Nagisa possess some sort of magic by now), Rei's lilac eyes travelled south; past the enticing strip of skin partly hidden by the halfway unbuttoned pajama, lower, and lower, until his vision saw clearly what was happening down under.

'Is this reality? Or is this yet another one of my despicable dreams?'

What Rei saw had him questioning his life choices: Nagisa had his hands preoccupied, his left grasping Rei's erection, and his right jerking off his own. His movements were far from smooth and languid; the strokes were rough, erratic and almost desperate, but for some reason, Rei couldn't look away.

A curious thumb swept over the slit of his length and Rei let out a shaky breath, his eyes closing in reflex of losing himself in the throes of pleasure. Driven by his desire alone -rationality and morals long forgotten-, Rei reached out to curl his hand around Nagisa's weeping erection, stroking it in tandem with Nagisa's hand, feeling the searing heat radiating and the rapid pulse on it. It should've been revolting; to touch another guy's arousal when he was never a batter for the other team to begin with, but somehow, like every other thing related to Nagisa, it was strangely enchanting.

"Nagisa-kun," Rei breathed out, voice husky and rasped, trying to get Nagisa's attention. But Nagisa seemed too lost and dazed to notice, so he grabbed the boy's hand to still him. His body screamed angrily at him, trashing and begging for the addicting friction to return, but Rei didn't want to just watch. He wanted to participate, to explore this intimate side of their relationship actively instead of just watching Nagisa doing all the work only because he was too much of a dumbfounded nerve wreck to know what to do.

He looked straight into Nagisa's eyes, deep creases between his tightly knitted brows, and asked.

"May I?"

Nagisa was confused at first, but then he looked down and saw Rei shifting closer, trembling hand still curling around his erection that was by now close enough to bump into Rei's own with the slightest of motion.

Oh.

Ohhh.

Nagisa didn't bother to provide a verbal reply; he let his actions speak his desires. He bucked his hips up, and their lower halves bumped against one another. Without hesitation, Nagisa grabbed Rei's hand, and together they started a rhythm; slow at first, gradually increasing in speed as the pressure built up. Asking for permission to let their erections touch was such a Ryugazaki Rei thing to do, and it was amusing, but Nagisa was too desperate for release to even laugh.

"Nagi—sa! Nghh…"

The little gasps and moans Rei was making were affecting him even more than their grinding and rhythmic strokes themselves, and Nagisa felt his completion edging closer and closer, the heat pooling in his groin almost unbearable. Amidst whatever that's left of his awareness, Nagisa barely noticed Rei's hips snapping forward in time with their hands moving lower to reach the bases and graze the coarse curls. He knew that Rei-chan was close too.

"Rei-chan… ahh… Together?"

Rei opened his previously tightly shut eyes to see a heavily panting Nagisa underneath him, cheeks a radiant pink and moist lips apart as if inviting him in for a kiss. He heard Nagisa's question, but his brain was too fizzed to come up with a coherent response. So he nodded lightly and leaned forward, capturing his lover's lips in a melting kiss, drinking the moans of ecstasy and pushing into their hands one last time before coming, vision blanked out with brilliant white and thoughts of Nagisa flooding his mind.

It's Rei's fourth attempt of getting up to fetch them fresh new clothes, what with the old ones strewn around somewhere below the bed, but Nagisa's undeterred cuddling urges and death grip around his waist rendered the mission simply impossible.

"We have school tomorrow." Rei tried to reason, inwardly thankful that at least he had the box of tissues on the nightstand (he would rather not sleep in the sticky state of mess they were in after the little rendezvous they shared) but still appreciate it more if they were to sleep with comfortable clothes on instead of just half naked.

"We can deal with it." Nagisa whispered softly, nuzzling his head onto Rei's collarbone and making a small satisfied sound. "Night, Rei-chan. Love you."

Before Rei could reply, Nagisa had already drifted off to sleep. Poor Rei could only silently pray that he'd wake up on the bed, still covered in blanket the next morning and not on the floor, shivering to death.

"Goodnight, Nagisa-kun." Rei said, landing a kiss to the top of the messy golden hair, sinking in exhaustion.

[It was unsaid -partly because he had said it before but mostly because Nagisa was already too far gone in his wonderland to even listen- but Rei did have a little something to add to the simple greeting.

'Love you too.']

A/N: I can't write graphic scenes without laughing halfway through when typing 'dick', so for now I present to you this faintly lemon-scented chapter. More of Nagisa's (and possibly Rei's) possessiveness in the next ones! Hope you liked it. Reviews/comments/criticisms are welcomed. Do tell me what you think of this chapter :)
