The Knowledge Of It (Kakashi X Iruka)

The marvelous smut of Kakashi X Iruka.

I know there are a few people out there who see Ruru as a seme, but for me he's always going to be uke - I mean, Dolphins are smart and they can fend off sharks.. but they ain't semes.


The shore along the small lake outside Konohagakure was always quiet, especially on nights like tonight, when all the young shinobi were called inside to have one last dinner with their parents before school started back up. Only the older ninjas were out now, not that any of them had anything important to do tonight anyway.

Such was the case with Umino Iruka. The nineteen year old had nothing to do - he’d written up all his teaching plans for the year, for all his classes; he’d assessed the talents and weaknesses of all his new students; hell he’d even begun memorizing names! Perhaps he did get a little carried away.

Was Maito Gai actually right?

Iruka scoffed and walked towards the water, pausing to take off his sandals. The air was still thick and sticky, the days were still hot, and so the water felt good right about now. It was at that temperature where it was just cold enough to make goose bumps rise over his skin.

He smiled a little and closed his eyes for the breeze, his mind blank for the few moments he was lost to the world around him.

This was the last bit of quiet he would get for about a month - the first month, with all the back to school ruckus, was always chaotic. Iruka was glad school was starting back up, but he would be even happier a little later in the year, once the children learned he wasn’t as easy to pull one over on as he seemed.

He chuckled and started back towards the village, kicking the water as he walked and wetting the bottom of his pants - he found he didn’t really care.

This was his last stop before he retired for the night - he always came here before he went to bed. He wasn’t sure why, he’d come to terms with the death of his parents, he had even been able to talk about it with others in a proud way before. It was just a ritual, he supposed, since he’d done it every night after they died it had become embedded into his nightly schedule.

Iruka reached out and gently laid his hands over the names of his parents, smiling softly to himself, though his kind eyes were pulled back in bittersweet sorrow. How different would he be if they were still around? How different would everything be if they were still around?

His mind wandered to Naruto and he chuckled as he drew his hand away.

It hurt, his loss, it was always nagging at the back of his mind - but there were others like him. There were those who had suffered more than he had suffered. There were those who needed his help. He had a lot to live for; he had a lot to look forward to.

He shifted his wieght a bit, wet feet feeling odd in his dry sandals as he leaned forward.

“’Night,” he whispered, his voice light and completely at ease with itself, alone in the vast soundlessness of the area.

As he stepped back his eyes wandered over some of the other names and he felt a small shudder run through his body before he turned and started his slow trek home.

~~~~

He dropped his sandals just inside his room, and paused to stretch as he flicked on the light. His chocolate brown eyes landed on his clock and he raised an eyebrow: it was much earlier than he thought it was. He must have walked quicker tonight than he normally did.

He was excited about school.

He’d be damned if he let Gai know it, however. He’d just be ostracized for it again - like he’d been at dinner the other night.

He started towards the small refrigerator in his kitchen but shook his head just before his feet met the cold tile - no, a snack before bed wasn’t really a good idea. He’d have a big breakfast instead.

He turned and pushed open the sliding glass doors which led onto his balcony - his favorite part of his apartment. He wasn’t quite sure why, it wasn’t like he had a great view or anything, he just really enjoyed the balcony. He was on the first floor, so it was more like a patio, though it was definitely a good five feet off the ground - Kakashi had proven that a year or so ago when he’d suddenly appeared at Iruka’s railing, giving that pitiful little puppy dog look he seemed to reserve for only Iruka.

The brunette chuckled and leaned onto the railing on his elbows, clasping his hands together as he decided to take in the scenery despite its unimpressiveness.

Konoha was so peaceful at night, so calm and quiet. For a few moments it seemed to just suck away his doubts, his worries and his pain - and then the moment would pass, and he would remember it all, just as bad as it had been before.

He smiled a true, soft smile.

He wouldn’t trade in his life for anything. He wasn’t sure there was a single other person in all of the world who was as content as him at that very moment. It seemed like everything was finally…

Perfect.

Iruka pulled a towel over his head as he stepped into his pajama pants, closing one eye under his unruly hair. He stumbled out of the bathroom amidst a cloud of steam and reached up to rub the towel viciously over his wet hair.

He loved long showers, the water was warm and calming and it was always a good way to kill time. Plus they tended to make him tired - not that he did anything tiring in the shower! - he had just always gone to bed after hot showers as a kid, and his body got used to the routine.

He stepped onto the cold tile in his kitchen, making a bit of a face as he started to walk on the sides of his feet; he hated cold tile on his bare feet. He fished through his freezer for a moment before removing an ice tray, grabbing an empty glass from the dish rack.

Humming to himself he cracked the ice tray and dumped all six pieces into the glass, poured some fresh water into the empty holes, replaced the tray, and filled the glass half-way with water. He turned and leaned back against his sink to take a sip of the cold water, the towel slipping to the countertop as he did so. His hair was about as dry as it was going to get anyway, and it was too late for him to sit up and blow dry it - not that it mattered, his hair was too fine to really care one way or the other.

He snickered and started towards his bed in the far corner of his room. The headrest sat just under a large window - perfect for those lazy Sunday mornings when he had nothing to do.

He set the glass of ice water down on his bedside table and pulled down the sheets as he began tugging down his pants. A light flush fluttered briefly over his cheeks as his hands paused on his boxers, trying to decide if he wanted to sleep nude or not. It had been a very humid day, sleeping without the added insulation of clothes would feel good - or so he told himself as the boxers slipped around his ankles. He stepped out of them gingerly and climbed into bed.

He took a moment to adjust his hair on the pillow and rolled to his side, smiling at the pictures on his bedside table. He and his team and sensei. He and his parents. Gai and Kakashi, drunk and ready for a fight.

Naruto.

He chuckled and rolled to his other side, closing his eyes and settling in for a peaceful night.

~~~~

The street outside Iruka’s small apartment was empty, silent - and then suddenly, out of the darkness, a pair of sandals hit and pushed off, followed by another. The third pair stopped, skidding slightly on the dry ground and turned, angling towards the short patio/balcony on the bottom floor. The first two ANBU chuckled from up ahead, but continued on, knowing the third member of their party could catch up after he’d played ‘peeping tom.’

Kakashi felt like he hadn’t seen Iruka in ages. Over the past couple of weeks his schedule had been filled with mission after mission, leaving him home for sometimes only hours in-between trips. He reached down and touched his left side, right above his hip, where a deep gash served as a reminder of another close call. He’d had too many of them lately - his team said it was because he wasn’t concentrating, because something else was on his mind.

They were right - so right.

He sighed and kicked off the ground again, landing on the railing of Iruka’s small patio/balcony. He walked carefully towards the edge and crouched down, reaching out to knock on the window - but he hesitated and draped his arms over his legs with a smile.

Iruka had gone to sleep with his hair wet and down - it stuck out over his pillow in strange, almost flame-like patterns. He looked as if he were lightly asleep, his breathing even but his eyelids still. Kakashi traced the line of Iruka’s scar with his right eye, still smiling behind his mask.

A few months ago Iruka had nearly cornered the white-haired shinobi, and insisted they discuss what happened on a certain night a couple of years ago with Maito Gai. Kakashi chuckled, but realized Iruka was quite serious. He started to explain that they were all quite drunk, and that as far as he could remember there were no protests, but Iruka stopped him with a sharp shake of his head and an anxious glance. ‘No’, he said. Something had happened between he and Kakashi, and he wanted to know - he needed to know, what the ANBU thought. Was it just a drunken passion or did Kakashi really feel something for Iruka?

Kakashi hadn’t been able to answer. He made up some lame excuse and took off.

Lately things had become more comfortable, but Kakashi still felt guilty when Iruka looked at him, and Iruka still blushed when they met eyes.

Iruka had sad eyes.

Kakashi was brought out of his thoughts as Iruka rolled over in bed, dragging the sheets with him. Kakashi raised his eyebrows; he hadn’t known Iruka slept nude. He held in a chuckle and reached up to gently place his hand on the window, tapping with his forefinger in a light rhythm.

Iruka started, his eyes flashing open and his heart nearly stopping as a few quick raps came to his window just as he was about to succumb to sleep. He slowly turned his head to look up through his hair and a blush spread quickly with the shock on his face.

“K-kakashi-san?” He muttered as he sat up, and immediately regretted it. He began pulling frantically at the blankets to gather them into his lap, his hair still bent at odd angles as he reached over and opened his window, looking quickly away.

“I didn’t mean to scare you,” Kakashi said, and though Iruka could tell he was smirking under his mask his voice sounded sincere, “I just - wanted to talk with you before I left again.”

“Again?” Iruka scooted a little towards the end of his bed, a clear invitation to the ANBU. “They know that you do need sleep, correct?” He muttered in a bitter way, leaning down to pick up his pants, though how he was going to get them on without giving Kakashi a glimpse of himself he didn’t know.

He tilted his gaze slightly as Kakashi stepped gingerly onto the window sill, and then to the floor, standing in the small space between the head rest and the night table. He shoved his hands into his pockets and took a moment to look around Iruka’s room.

The brunette had the strangest of thoughts as he watched Kakashi, and couldn’t help but look at him completely. He seemed - nervous, unsettled, ruffled even. What did he want to talk about that would make him loose his composure like this? Granted Iruka could only tell because he’d grown up with Kakashi, he was sure any onlookers would see nothing wrong, but the way Kakashi’s eye scanned the room, the way his foot tapped just gently against the floor - he was nervous, really nervous.

Iruka swallowed and opened his mouth to say something.

“Kakashi-”

“Iruka-”

They both laughed, short nervous laughs, and then silence again. Iruka fingered the pants in his hands, bringing the blankets over to cover all of his bare legs as Kakashi continued to fidget just slightly, eyes resting on the floor at Iruka’s feet.

“Wh-why don’t you go first..” Iruka said in a moment of strange calm and courage, looking up to try and meet Kakashi’s eye, though he knew he wouldn’t be able to hold it long, “you’ve got a mission waiting - I’ve just got sleep.”

Kakashi smiled and chuckled again lightly at Iruka’s small shrug, the blush over his features that made him look about fifteen - of course the lighting wasn’t helping either. He found his eye tracing over the line of Iruka’s hair, glad the other boy couldn’t see his smirk. He loved it when Iruka let his hair down.

“I just - do you remember, a few months ago, the conversation we had near the academy?” Kakashi started, finding he could no longer look at Iruka. His throat tightened and his heart began to move higher with each pound, until Kakashi was sure it had moved up behind his tonsils. He’d thought about this, mulled it over for days, until he unknowingly worked up a speech to give the younger man - but he couldn’t remember any of it. He recalled bits and pieces of the way the scene would play out in his head, but not enough to give him solid footing.

“H-hai.” Iruka said after a long pause, his voice slightly shaky.

For some reason Kakashi was put almost immediately at ease. Iruka sounded scared, like he knew what Kakashi was going to say next -when he didn’t. Nothing Kakashi was about to say would solidify anything between them, but it most certainly wouldn’t be what Iruka was thinking. Maybe- maybe he would even smile. Kakashi felt a heat rise in his cheeks that caught him off guard.

“I wanted to… to tell you that - I want to know you, Iruka-kun. No-not in a sexual way, I mean - not not in a sexual way. I - uh.. I just meant that - I don’t really know much about, um, you as a person and I’d - I’d like to spend time with you.. Figure you out. Uh, not like - like you’re supposed to do with an enemy, o-or a dangerous situation, bu-but like .. A person, I suppose.” In that fraction of a minute Kakashi had shattered all the confidence he’d brought with him. He’d completely lost his composure and his cool demeanor and steady voice went flying out the window.

Iruka was in love.

The younger shinobi’s jaw fell open lightly as he stared at the white-haired boy pinned against the wall. Kakashi was flabbergasted, and blushing - he was nervous, pressed against the wall as if he was trying to vanish into it. For some reason, seeing this side of Kakashi made Iruka’s heart melt - made his skin tingle and his throat lock up.

He wanted to say something - he wanted to break the silence - but he couldn’t think of anything to say. What was he supposed to say to that!?

He smiled - and then started to chuckle, stunning even himself. He looked up at Kakashi after a moment, still grinning.

“Arigato, Kakashi-san, it’s alright - I know what you meant. Arigato.” Kakashi’s eyebrows knitted together and a strange expression crossed his face, most of it hidden. Iruka was practically glowing, the way he smiled and laughed, the way his scar crinkled just the tiniest bit when he scrunched up his nose. He wasn’t sure why Iruka’s words calmed him, but they did - he didn’t even register them, but the tone in the brunette’s voice, the look in his eyes, and Kakashi was better.

He took a few steps away from the wall, his hands having somehow freed themselves from his pockets, and sat on the bed, rather close to Iruka. He paused, looking at his hands as he clasped them in front of him.

He should go now. He should thank Iruka for hearing him out, for letting him in - and then he should go. Close the window and finish his mission. Save whatever dignity he had left.

He unclasped his hands and reached up to fix Iruka’s hair without even looking, feeling goose bumps rise over his arms at the noise Iruka made - a sort of surprised noise. He took a deep breath and lifted his hand again.

Iruka didn’t know what to do now. His small bout of confidence was gone, and he was squeezing his pants again - nervous with a blush on his face he was sure made him look like a child. He shook his head lightly, setting his newly arranged hair behind his ears and turned to look at Kakashi.

“Uh-” He paused, his eyes growing wide. Kakashi had turned to look at the exact same moment, his forehead protector and mask removed. Iruka knew what to expect, he’d seen Kakashi’s full face four years ago - but it was the act of trust, the blind act of trust which shocked the teacher.

“I - like your hair down.” Kakashi said, startling Iruka again. He sounded so - far away and young, as if he’d suddenly remembered he’d never had a childhood - as if he’d suddenly become a shy teenager on his first date. The Chuunin reached up and pulled a lock of it into his face, looking at it disdainfully for a minute.

“I-I think it makes me look like a girl, when it’s down. Maybe I’ll cut it.”

“No.” Kakashi said suddenly, again surprising them both. He chuckled, and Iruka got to see the curves of a small, magnificent smirk on his lips. “You don’t look like a girl, your eyes just stand out.” He reached up to trace a thumb under Iruka’s eyes to illustrate, his hand more steady than he thought it should have been.

Iruka’s cheek fit perfectly into the palm of his hand as he cupped it around the younger ninja’s face, tilting it slightly. His heart stopped completely as he watched Iruka lean into his hand and close his eyes in an almost desperate way -as if this one touch was all he had ever wanted.

He needed to get back to his mission - but it could wait. This moment would never happen again.

Kakashi leaned forward, hoping it wasn’t a mistake, and closed his own eyes as he brushed his unused lips over Iruka’s in a kiss so quick it was hardly a kiss at all.

Iruka didn’t jump or make a noise or start or anything, the touch was so small he simply opened his eyes to meet Kakashi’s, a serene sort of longing on his face. He felt Kakashi’s thumb rub over his cheek softly, shaking a little, and he took on Kakashi’s usual half-lidded expression, looking more seductive than he knew. This was the longest he’d ever held Kakashi’s gaze and it gave him a sort of light-headed feeling, making him tip into the hand just a bit more.

Kakashi was amazed by the little looks Iruka gave him, and he didn’t even try to second guess himself as he lifted his other hand and gently stretched it over Iruka’s neck, high on the back so he could reach his fingers through faded ebony locks.

As Iruka reached up to take Kakashi’s wrist in small hands the ANBU leaned forward again, this time making strong contact - reigned passion behind his lips.

Iruka was slightly startled this time as Kakashi’s fingers tightened lightly at the roots of his hair, but he leaned into the kiss all the same, reaching out with his other hand to touch Kakashi’s chest, somewhere beneath the tight ANBU armor. His pants slipped from his lap and landed on the floor, but, despite the cliché, Iruka didn’t care or notice.

Kakashi’s lips were so sweet, so firm and perfect, why he hid them under his mask Iruka would never know. He felt a strange purr run over his tongue and he blushed deeper - realizing it had been Kakashi, holding himself back. Did he think he was going to hurt Iruka? Was he not sure about what he was doing?

Iruka frowned but managed to pull himself away from the lip lock, knitting his eyebrows together.

“I-I want you to know th-that I’m not g-going to stop you, K-kakashi-san…” He said truthfully, the blush and expression on his face belaying the confidence in his voice. “B-but be sure you w-want to do this… A-and - you won’t break me, I-I promise.” He said, a small almost embarrassed smirk over the corners of his lips.

He watched Kakashi process his words for a moment, the sharigan almost expressionless as it scanned the truth behind Iruka’s voice.

“Y-you won’t stop me?” Kakashi said, his voice now sounding hoarse. His hormones were battling with his mind - he knew this should stop, there were so many reasons for him not to continue - but, God, he wanted this, and apparently so did Iruka.

The brunette shook his head lightly, his fingers petting Kakashi’s chest in an anxious way as he tried to hold his gaze even longer, but eventually looked away. He felt his heart thud hard against his ribs, and he manipulated the hand in Iruka’s hair to turn the boy to look at him once more.

“Promise me -” He started, holding Iruka’s gaze with a far-away sort of fierceness, “that if we- that if I do something.. Y-you don’t like… Promise me that… that if I hurt you- you’ll-”

“I promise.” Iruka said as he leaned forward and rested his head under Kakashi’s chin, his arms moving up to grip the ANBU’s shoulders. Kakashi had the most delightful smell, and pressed up against him Iruka could find it - hidden somewhere under the stench of blood and sweat. Iruka knew that no matter how many times you washed your clothes, those smells never came out - it almost made him sick sometimes.

He felt Kakashi’s arms slowly wrap over him, on hand resting between his shoulder blades the other moving slowly to his lower back, stopping just under where his pants would have been. Iruka had another strange thought - he wondered if maybe Kakashi was so uneasy not because he was scared he would hurt Iruka, but because he didn’t know what he was doing. He knew that on some level Kakashi knew exactly what he was doing, he’d done it before with the added distraction of Gai, but this time it was definitely different. Kakashi had expressed a sincere feeling to Iruka, now there were strings attached, it wasn’t just drunk sex, he had a commitment now.

Iruka slid his hands down Kakashi’s shoulders a bit, closer to his chest, and found the zipper down the chest-piece of his armor. He felt Kakashi stiffen slightly, but he didn’t move other than to rub his fingers between Iruka’s shoulder blades. He was still unsure about the whole thing - hesitant. Iruka felt selfish, but he knew Kakashi would stop if his mind made itself up to do so, and so he continued. He gripped the tag of the zipper and leaned slightly to one side so he could pull it all the way down, exposing a dark blue shirt pressed tightly against taunt and tired muscles.

Kakashi had closed his eyes when Iruka leaned closer, and hadn’t opened them since - he wasn’t sure why. They slowly opened, just a fraction, as he felt Iruka finish with the zipper on his armor, and pause, fitting his tiny hands to the sides of Kakashi’s chest. He would have to let go of Iruka in order to undress himself, the former of which he was not ready to do.

He managed to slide his arms from around Iruka and began unsnapping his gloves and arm-guards, dropping them rather hastily to the floor. He then slid his bare arms out of the white chest-plate, and that too was discarded haphazardly. He reached back up, body fueling itself on adrenaline now, and pulled Iruka in for a desperately passionate kiss.

He felt his body pound, his thighs shake as a rush of blood passed around them, and he felt slightly upstaged at the fact that Iruka was already nude. He shifted his position on the bed enough to unfasten and kick off his sandals, which was immediately followed by a grunt as he struggled to remove his shirt, nearly ripping it as he tossed it off the bed.

Iruka was taken aback as the now bare-chested Kakashi suddenly leaned onto him with enough force to knock him to his back on the bed, his head just barely hanging of the end. He closed his eyes as Kakashi brought him in for another kiss, a moan passing through his lips as the ANBU’s hands barely touched his genitals in the attempt to unbuckle his pants.

Something about seeing Kakashi like this put Iruka at ease - even though he knew it was just a bunch of over-acting hormones and the revenge of an under-exposed sex drive - he felt so much better now that Kakashi was taking the lead, acting desperate and feverish.

“Damnit..” At first Iruka wasn’t sure what Kakashi had said, but his mind deciphered the words as Kakashi pulled back, sitting up on his haunches to fix the mess he’d made of his pants and boxers. Iruka blushed and brought a hand to lay over his chest, leaving the other one to curl around the blankets gathered at his hips. The younger man was rewarded with a brief glimpse of snowy white hair and a rising erection before Kakashi’s pants were kicked from his ankles and he was pressed atop Iruka once more.

Kakashi tensed as he felt Iruka jerk under him, and he closed his eyes as he realized he could feel each and every curve of the brunette’s body under the blankets - he could feel the smaller man become hard under him. He slid one hand up Iruka’s chest, making the other man suck in a deep breath, while the other he steered towards the hindering blankets.

He rocked back onto his knees and the balls of his feet as he pulled the blue fabric away, revealing Iruka’s full nakedness. Kakashi looked back up at Iruka as one of the man’s hands came down as if to hide his own arousal with a sort of childlike shame. The expression on Iruka’s face was instantly locked into the ANBU’s mind, one for later use when he was alone.

He leaned in for another kiss to distract Iruka as he moved his left hand down, past Iruka’s own hand, through the patch of hair, to wrap around the modest erection.

“Uuh!” Kakashi turned his head to kiss the side of Iruka’s neck as the other man’s back arched just enough to put space between his shoulders and the bed. Kakashi pulled his fist up Iruka’s length gently, enjoying the feeling of Iruka’s newly placed hands kneading at his lower back and shoulder blades. He pulled his fist back down, and up once more, smearing pre-cum over his fingers - a sort of make-shift lube in unprepared times such as this.

He released Iruka’s erection reluctantly, leaving the other man panting and biting his lip, to slide his fingers further between his legs. He stopped however, and slid his other hand down Iruka’s form as well, nearly making the teacher moan. Kakashi moved his hands to the underside of Iruka’s thighs and gently eased his legs apart, laying them on either side of himself and making both ninja blush a ridiculous amount.

Iruka quickly stuck the knuckles of his right hand into his mouth, turning his head away slightly and biting down as he closed his eyes. Something about the act of being fully exposed made his whole body shudder; knowing that he was now almost completely at Kakashi’s mercy, well, a few more minutes of that and he wouldn’t need another hand-job to finish up.

“Huhn!” He arched his back slightly and tilted his head to look at Kakashi as there were suddenly two fingers between his legs, prodding softly at his opening. He closed his eyes and dropped his head back to the mattress in a sort of silent permission. His crotch practically hummed as Kakashi leaned up to smother kisses over his chest, wasting very little time in pressing both fingers into Iruka. He sucked in a breath and held it, but Kakashi knew what he was doing and he bent his fingers slightly hitting the prostate with an almost frightening accuracy.

“Ahh!” Iruka shouted, then quickly pulled his bottom lip into his mouth to quiet himself. He felt Kakashi’s warm tongue just under his nipple and squirmed as the fingers were pulled out slowly, leaving behind a barely noticeable burning sensation. It wasn’t long before they were thrust back in, further this time, curving as they were removed. Iruka moaned and curled his toes against the bed sheets, feeling his erection shudder.

“N-not so…” He gasped, arching again as Kakashi’s speed continued to pick up, “fast!” He cried out as the fingers were one again thrust into him and curved, hitting the spot just as expertly as they had before. He felt a sort of strange tightening all through his body and then a release.

“Ah-uh!” Kakashi’s eyes widened as Iruka suddenly orgasmed, shooting a single thick white stream onto his lower abdomen. He tilted his head up and kissed Iruka’s neck lightly, enjoying the flushed, contented look on his face - though his throbbing, almost painfully needy erection gave him little time to enjoy the look.

He shifted to his knees, holding himself up with his legs as he slid his arms once more to Iruka’s thighs, lifting them, bending them gently towards the man’s chest. He slid his arms up, towards the back of Iruka’s knees, and folded them over his shoulders, tilting his head to kiss the inside of Iruka’s left thigh.

He tilted his head to look up at Iruka, to give him one last chance to say no. The teacher was far too gone to make coherent thoughts, or so it appeared. One of his hands was tangled into the sheets, pulling and twisting, the other had woven itself into his hair, furthering it’s state of disarray.

Iruka finally met Kakashi’s eyes and smiled, nodding even under his bright vermilion blush. He tried to relax, tried not to tense himself up as Kakashi moved his gaze, tightened his hands on Iruka’s legs, and thrust.

“Gyyyah!” Even though Kakashi had spent a far amount of time warming Iruka up, the feeling of the ANBU’s full erection completely penetrating him left him breathless. It didn’t really hurt, not this part anyway, it felt strange, of course, but it also felt good - to a certain degree.

Kakashi wanted to make sure he wasn’t hurting Iruka, but he was lost to everything but the feeling of Iruka’s tightness around his erection. His hands fell from Iruka’s thighs to the bed, where he gripped so hard he could almost hear the fabric ripping. There was a slight slap and a sting to his shoulder and he tilted his gaze as much as he could, his vision white, to see Iruka’s hand clamped tightly over his shoulder.

“J-just…” Iruka breathed, his eyes close in what was a clear combination of bliss and agony, “go-go slow..”

Oh, those words. Something about those words. Kakashi felt a throb pass through his whole being, making his body nearly vibrate, and he nodded. If Iruka wanted slow, Kakashi would go slow. He tightened his grip on the sheets and pulled out, earning a slow sort of hiss from Iruka. When he had come out nearly all the way he slowly eased back in, clenching his jaw closed tightly at the sensation.

He had to - go slow.

He gasped and tucked his head in so far his chin touched his chest. He began to find a rhythm, a painfully slow rhythm of in - nearly out - and in. With each new penetration Iruka tightened unconsciously, and sent Kakashi spinning. He could go for quite a while when he masturbated (not that he took great pride in it) but he knew he wouldn’t be going for nearly half as long this time. It was different when another person was involved - and not just any person, one you.. Truly wanted.

Iruka let out a short cry of pain and moved his other hand to Kakashi’s hair, pulling at the roots lightly, drawing blood from his bottom lip as he bit down a little too hard. Even going slow the feeling of Kakashi pulling out left a burning sensation behind, one that got no better with time. It was worth it, though, it really was.

“Ahh!” Iruka shouted, scooting back on the bed as Kakashi gave a few particularly rough thrusts - and then came. Iruka winced at the strange sensation, his lower abdomen filled with a delicious warm and burning feeling that took away from the irritation between his legs.

He shakily laid his hand on the back of Kakashi’s neck, rubbing his thumb at the base of his hair lovingly as they both came down from the momentary high.

Kakashi left quickly once he’d caught his breath. He dressed with a small groan and took off through the window, pausing as Iruka leaned out and called his name.

“B-be careful.”

There was a beat during which they looked at each other, right before Kakashi pulled his forehead protector down. A beat where they knew the thoughts of one another, a beat where they knew - it was just this.. Just the knowledge of it.

They smiled.

Iruka would have to try hard to hide the pain tomorrow, during class, but he would manage - and when his classroom was empty, one no one was looking, he would smile and blush.. And no one else would know why.
