A/N: Thanks to all my reviewers! I'm glad you all enjoyed the last chapter. The experiments are complete and things are beginning to wind down. Soon the semester will wrap up and with it this story. There are a couple chapters left yet so as always, I appreciate reader input. Are there any other loose ends to be tied up? Any questions left unanswered? Let me know!

Warnings: Please enjoy this lemon - I squeezed it just for you.

Disclaimer: I don't own Naruto and I do not profit from this fic. I do receive warm and fuzzies from my reviewers, but I cannot pay the bills with those.

"So what do you think Iruka is going to say?" Naruto asked as he and Sasuke made their way up the stairwell.

Sasuke shrugged, "Depends... how incriminating do you think the videos are?"

Naruto mocked a grimace, "I think we are gonna have some explaining to do."

They arrived at the office only to find Jiraiya alone in the room. He smiled at the boys as he moved out from behind the cluttered desk, "Iruka is pretty busy this week, you know end of the semester and all. What do you have for him?" Naruto and Sasuke both pulled out their cameras, handing them over the the white-haired man, "I see. Excellent. I will make sure Iruka gets these. He will need time to check the documentation, how about you come back Wednesday?" The boys nodded and Jiraiya set the cameras down on the desk, "Oh and when you come back..." he turned and rummaged through a stack of papers on the desk, "bring these with you." A packet was handed to each boy, they looked down and back up curiously. Jiraiya crossed his arms over his chest, "Exit questionnaire."

"Dammit," Naruto flipped through the pages of the questionnaire as he shoved fries in his mouth, "there are like 20 questions."

Sasuke smirked, "And here I thought the point of extra credit was so you could be lazy."

Naruto glared at the raven-haired boy and looked back down, "Some of these questions are ridiculous..." Naruto flipped through the pages, "'Did you ever feel you were no longer consciously in control of your actions?' What does that even mean?"

Sasuke shrugged in response. He himself was uncertain what he had experienced over the course of the semester or how he felt about it. The only thing he knew for certain was that these experiments had allowed for events to unfold; events that he had wished for but had been unable to bring to fruition on his own. Whatever the value of these experiments to Iruka, Sasuke saw their value to himself.

Naruto huffed and pushed the packet away as he brought his soda to his mouth, twirling the straw with his tongue, "So Sasuke... got any plans after Statistics?"

A dark eyebrow arched as obsidian eyes followed the pink muscle. Sasuke sighed, "Unfortunately."

Lips closed around the straw and Naruto sucked lightly, his azure eyes swirled with lust. Sasuke's stony resolve waged an epic battle with his hormones; responsibility combating desire. It was the end of the semester... he had shit to do and sadly Naruto was not on that list.

Sasuke frowned, "I have a study group then I need to work on my German oral."

Naruto smiled, "What a coincidence I also have some oral to do..."

A lesser man may have blushed, Sasuke simply smirked, "How about tomorrow?"

"I don't know," Naruto pursed his lips in consideration, "I really have to get started on my history paper. Maybe if I get a good start I could take a study break."

Onyx eyes rolled as Naruto waggled his eyebrows. This was going to prove to be a frustrating couple of weeks; study groups, essays and test anxiety threatened to cock block them at every turn. Not to mention their omnipresent roommates. Sasuke couldn't wait for the semester to be over, the three weeks of winter break would prove to be the best holiday in years. Sasuke's brow furrowed ever so slightly, the break would only be good if he was able to spend it with Naruto but there was no way he could get away with skipping Thanksgiving and Christmas – his mother wouldn't have it. Sasuke's eyes grew distant as he considered his options.

"Sasuke?"

The pale boy snapped back and offered the blond a small smile as he stood up, "I have to get going. I'll see you tomorrow."

Naruto followed Sasuke to the trash and tossed in his wrappers. He caught the raven-haired boy by the wrist and pulled him back. They stood chest to chest in the cafeteria entrance, a few people tossed them a wayward glance – judgmental eyes disapproving of their proximity.

"Don't think you can leave just like that," Naruto whispered in a low foreign tongue before leaning in.

The millisecond that Sasuke hesitated rekindled feelings of cowardice. He was so tired of restraining himself for the sake of sanctimonious onlookers. Embers of trepidation were swallowed by temerarious flames that licked at his desire.

The resulting kiss was neither tender nor chaste. Sasuke's mouth ravaged Naruto's in a display of defiance. Naruto clutched at Sasuke's jacket as the pale boy's tongue clashed violently with his own; his legs threatened to give out under the intensity of the exchange. Sasuke's searing, slick muscle invaded the depths of Naruto's mouth, coaxing out a wanton mewl. The pale boy pulled back and smirked at the panting blond who was still clinging to him for support.

"Wha...?" Naruto asked softly, eyes betraying his dazed state.

Sasuke's smirk grew more satisfied as soft Japanese fell from his lips, "Just get your fucking paper done."

"Come in!" Naruto shouted from his chair.

Sasuke tossed his bag to the floor next to Naruto's desk and leaned over the blond's shoulder to see how much he had completed. Pale lips quickly fell into a frown.

'Charles Darwin by Naruto Uzumaki'.

"Seriously?" He deadpanned and looked down to mess of blond spikes, "That is all you've done?"

"I know!" Naruto growled and tilted his head up to offer Sasuke an apologetic smile, "I just don't know what to do. I've got all my resources..." Naruto waved his hand a stack of books on his desk, "but I don't know what to say."

Sasuke moved to the pile of books and sifted through the titles, "He was born, he sailed around on a ship, he wrote a book, he died." Midnight eyes returned to Naruto, "Done."

Naruto heaved a sigh, "Not good enough. Professor doesn't want a biography. We are supposed to highlight some feature of their life, something that isn't necessarily what they are known for, but everybody knows Darwin," the blond turned to his computer and growled again, "stupid fucking Darwin."

Sasuke rolled his eyes, "It really shouldn't be that tough. His research was very controversial... you should talk about that. The social ramifications of his work rather than the work itself." He flipped absentmindedly through a rather thick text, "You know he was in seminary or some shit before he wrote 'Origin of Species'?"

Naruto turned and blinked at the pale boy, "Sasuke... you are a genius."

The raven-haired boy shrugged as if the comment was old news. His dark eyes returned to the near blank screen, "So how many pages?"

Naruto pursed his lips, "Five plus bibliography."

"Five pages..." Sasuke repeated as he looked around the room, "and where is Kiba?"

"Uh..." Naruto furrowed his brow, "library maybe."

Sasuke nodded, "So here is the deal," he spun the blond around in his chair, "for every page you finish I will give you five minutes to do..." obsidian eyes flared, "anything. And if you finish the paper before Kiba gets back..." he shrugged and took a step back.

Naruto spun around to his computer and grabbed a book. Sasuke smirked as he walked around to Naruto's bed, the sound of furious typing filling the room. Nobody could say Sasuke wasn't a good tutor.

Naruto was supporting himself with the wall as Sasuke knelt before him. The raven-haired boy was employing every weapon in his arsenal; his right hand slid leisurely up and down Naruto's shaft while his left prodded playful at the blond's puckered hole, with his mouth he gently sucked on Naruto's sac – scraping his teeth along the skin before offering a contrite lap.

Naruto growled as he looked down, admiring the pale face buried between his legs. But Sasuke wasn't looking up at him, the bastard didn't even have his eyes open. His ministrations were as magnificent as they were frustrating – Naruto's climax remained just out of reach. If those smoldering eyes would look up, even briefly, Naruto would be able to cum. Of course, all of this was known to Sasuke and he purposefully kept the blond on the brink.

One minute left. One minute and it was back to the computer; the fifth and final page was all that remained to be completed and with it came the promise of Naruto's own completion. As every page had escalated Naruto's reward – there was only one thing left upon finishing his paper.

Page one had earned Naruto a heated exchange of tongues, lips and teeth. Sasuke allowed the blond to pin him to the bed and be plundered. It was a rare occurrence that Naruto dominated the pale boy and it was a refreshing change of pace. Sasuke appreciated the blond's passion and didn't mind the aggressive force of Naruto's tongue clashing with his own.

The second page brought skin into the embrace. There were no pleasantries exchanged as Naruto stood up from his desk, walked over to the pale boy on his bed and pulled Sasuke's T-shirt up and off. Within seconds Naruto was in the same state of undress and bare torso's pressed together as their mouths collided. But they didn't stay locked for too long, soon lips and tongues found themselves wandering across flesh – sliding over muscle, flicking against pulses, sucking on dusky nipples. Five minutes were officially up just as Sasuke's tongue dipped into Naruto's navel.

After page three they picked up more or less where they had left off. This time Naruto was on top, grinding down and hissing as clothed erections were pressed together. Tan fingers pulled at the button to Sasuke's jeans and the pale boy shifted his hips to help release it. Naruto ran his tongue up Sasuke's taut stomach as his hand pulled down the zipper. He brought his head lower and lower, planting soft kisses along the way. With the denim out of the way Naruto brought his teeth to Sasuke's hard length, gnawing lightly through the fabric of his boxers. The pale boy shuddered at the sensation and just as the tan hands returned to finally release him – five minutes were up.

So Sasuke may have been a little sadistic as he rolled one of Naruto's balls against his tongue – but the blond started it. None of that mattered though, so long as Naruto could finish his paper before Kiba returned.

Sasuke perked up at the sound of whoop from the other side of the room. He closed his text book and moved off the bed; he needed no further indication to know it was finally time to take his pants off.

Pale hands paused as the door opened and closed quickly, "Naruto?"

The blonde sauntered around the corner, also in the process of undoing his pants, "Just giving Kiba a little warning."

Sasuke nodded and continued to strip. Naruto kicked off his boxers and for a moment the two boys just stood – eyes roving over the naked body of their lover. Naruto broke first, stepping toward the pale boy and pushing him back onto the mattress. Before Sasuke could offer a complaint the blond was straddling him, grinding lightly. He leaned forward, their hard lengths pressing together as he reached behind the raven-haired boy. Naruto didn't have a drawer to hide paraphernalia in, instead he kept a bottle of lube tucked firmly between the mattress and the wall.

Pulling back with his trophy in hand, Naruto smiled down at the pale boy. He slicked his fingers and handed the bottle to Sasuke. Naruto reached behind himself and slowly inserted two fingers; the intrusion caused a grimace, one eye squinting closed. The other eye drooped closed as the fingers began to pump steadily in and out of the tight hole.

"Naruto..." Sasuke breathed as he watched the blond prepare himself.

It was such a beautiful sight; eyebrows tweaked between pain and pleasure, sharp inhales and a steady rocking of hips. The introduction of a third finger was made known by the hiss released. Sasuke ached to be buried inside his blond.

Naruto's voice was thick as he spoke, "Sas... lube."

Tan fingers wrapped around Sasuke's hard cock. The pale boy gasped and fumbled to open the bottle. Naruto smoothed the liquid over the hot skin, stroking the length in time with his own pumping fingers. Wide obsidian eyes took in the erotic sight. Jesus, fuck. Naruto could not be outdone.

This had to be the most shameless and salacious thing Sasuke had ever witnessed. Naruto's eyes were closed, his bottom lip clenched between his teeth. His right hand was obscured from view, but the steady rhythm coupled with the rolling of hips spoke clearly of the activity. As if the ministrations of the right hand weren't sexy enough, the left held Sasuke's dick firmly – stroking and twisting to spread lube thoroughly across the shaft. Naruto's own erection was dark and pulsing, clear beads of precum rolling down from the head.

If it weren't for the promise of what was to come next, Sasuke would have wished for this scene to never end. Naruto finally removed his fingers from inside himself and slowly his eyes blinked open. The cobalt depths were screaming for Sasuke – they spoke of an insatiable need. Naruto did not release Sasuke's cock, instead he held the length firmly in place as he lifted himself up on his knees.

The blond positioned himself above Sasuke and swallowed subtly as he began to descend. He had never been in control before, the thought straddled the line between thrilling and terrifying. Naruto always depended on Sasuke to guide him through uncertain moments, but now he was in the lead. He felt the tip brush against his taint and Naruto maneuvered the length until he could feel it pressing against his entrance. Naruto bounced a little, feeling as the tapered head barely pierced the pucker. Feeling more confident the blond settled more of his weight against the tip. The sensation of being stretched made him feel strangely weightless, he lost the feeling in his extremities as all his attention was refocused to the intrusion. Naruto rolled his hips slightly, coaxing the hard length to sink deeper.

Sasuke watched with what could best be described as appreciation. Not just appreciation for the act that was taking place, but appreciation for what this undoubtedly meant to Naruto. He wasn't just taking control of sex, he was taking control of his sexuality. He was grabbing it by the reigns and commanding it. Sasuke had been serious before when he said that Naruto was strong, but the blond still had his reservations; now, as he slowly settled down on Sasuke's cock, Naruto was tossing aside all doubt. It truly was the fucking sexiest thing Sasuke had ever seen.

One achingly slow inch at a time, Naruto descended until he was hovering just above the pale boy's hips. The blond lifted himself up ever so slightly and brought himself down forcefully. Both boys cried out as Sasuke was finally buried completely in the tight heat.

Sasuke released a shuddered breath but his hands remained steady as they ghosted up tan thighs to grip Naruto's hips. Finding leverage with his knees, Naruto lifted himself slowly and Sasuke held him firmly as he slid back down. The blond repeated the motion, as little more this time – rising farther and falling faster.

"Oh God..." Naruto moaned as he found a steady rhythm, "Jesus... Sasuke..."

Azure eyes rolled back as Naruto groaned again. Sasuke's thick cock continued to slide in and out of him, stretching him deliciously. His head fell back as he cursed and cried out. The ecstasy created by penetration was entirely different from the sexual gratification he had grown accustomed to; it was nothing like have his cock stroked or sucked. It was the pressure – a deep pain coated in a viscous pleasure. And as the blond continued to impale himself on the hard length, he couldn't imagine how he had gone so long with out the sensation.

"Ahhh... fuck..." Naruto moaned as he rocked his hips harder, reveling in the way Sasuke' bulbous tip rubbed against him from the inside.

Onyx eyes darkened, lust seeping up from their depths, "That's right Naruto," Sasuke caught his lip under his teeth to hinder his moans, "ngghh... fuck... you like riding my cock... ahh... don't you?"

Under any other circumstance Naruto may have laughed or offered a hollow glare, but this was neither the time nor the place to be coy. The words spurred his actions further, hastening his pace and increasing his force. Slamming his body down onto Sasuke, his sac smacking against the pale abdomen and aching cock bobbing in time, Naruto released unrestrained sounds of pleasure.

Between wanton moans, Naruto found the strength to reply, "Yes... Sasuke..." several sharp inhales interrupted his response, "ahhh... ahhh... I love riding your... mmm... fat cock!"

Naruto lost himself to his screaming cries of ecstasy; his body fell forward, hands splayed out across Sasuke's chest. The pale boy tightened his grip around tan hips and forcefully pulled the blond up before slamming him back down. Naruto screwed his eyes shut tightly as he gaped in a silent cry. Sasuke lost himself to the rhythm, the hard and fast movement of the blond up and down his cock, and he began to thrust up. The blond cried out once more before biting down on his lip.

They collided violently – feeding off one another, extracting nothing but pure pleasure from each other. They were perfectly balanced; Sasuke's thick cock offered an ecstasy equal to that he received from Naruto's tight channel.

Naruto fell to his elbows and pressed his lips against Sasuke's. The rocking of hips against hips made the embrace difficult to maintain – teeth knocked together, lips and tongues slid against skin. The heated exchange was broken completely when Naruto arched his back, screaming out Sasuke's name. The pale boy cursed and thrust against Naruto's prostate again. And again. And once more.

The blond's moans grew to incoherent cries as Sasuke continued to plunder his ass. The raven-haired boy watched intently as the boy above him cursed between panting breaths. To know that he was the cause of Naruto's agonizing pleasure brought him a great satisfaction. Though not nearly as great as that which he was about to experience.

Thrusts grew frantic and Naruto found he could no longer control his rhythm. Their bodies moved greedily, searching for their impending climax. Naruto found his when he brought his hand to fiercely stroke his aching cock; white streams exploded from him, landing unceremoniously on Sasuke's chest and stomach. Sasuke came as the tight channel constricted around him, milking out his seed as the pale boy shuddered and moaned.

Naruto collapsed, falling into the pools on Sasuke's torso. He groaned in displeasure but couldn't be bothered to move. Sasuke brought his hands to stroke along Naruto's back, grazing the hot skin. The blond purred contentedly.

Kiba approached the door to his room with caution. The muffled sounds filling the hall seemed to get louder as he approached. He pulled a fluorescent yellow sticky note off the door and hung his head. 'Fucking' was all the hastily written note said. What happened to the days of hanging a sock on the doorknob? At least that displayed a hint of modesty. He shook his head and turned back down the hall.

Naruto shifted his gaze between the expectant eyes upon him. He wasn't used to Jiraiya being present during the psychological exam, the man's presence made him inexplicably nervous.

"I'd like to start," Iruka smiled reassuringly, "by congratulating you on completing the experiment. I know it must have been very straining."

Naruto's lips twitched up in a nervous grin, "Yeah, thanks."

The brunet tapped his pen against the file in his lap, "So, why don't you tell me about your experience?"

"Okay," Naruto chewed his lip, "well I really don't remember a lot of it. I mean, I remember the big stuff like the airport and the gun range..."

Iruka nodded, "Yes. There were definitely some... interesting scenes you recorded. Do you think any of the activities you engaged in were the result of the sleep deprivation?"

Naruto cocked his head slightly, "What do you mean?"

"Considering that impaired judgment is a symptom of sleep deprivation, do you think you would have still done some of the things you did if you hadn't been... under duress?" Iruka's soft eyes slitted slightly as he questioned the blond.

"Duress?" Naruto repeated, "We didn't do anything we wouldn't have done under normal circumstances. Sasuke would have punched his brother, we would have gone to the gun range, I would have f-uh..." he stammered to a stop and shifted his eyes to the floor, "I don't think our judgment was impaired."

Iruka nodded and scribbled on the page in his lap, "Go on. Did you experience anything unexpected? Odd sensations or hallucinations?"

Naruto pursed his lips as he pondered the question. His eyes slowly widened, "ah ha ha," he laughed nervously, "I had a little confrontation with Kyuubi."

"Kyuubi?" Jiraiya questioned.

Iruka leaned over to his adviser, "Manifestation of subconscious."

"Ahh..." the white-haired man nodded.

"Continue," Iruka looked back to Naruto with a smile.

"I didn't see him this time, he was just in my head. It was nothing really," the blond shrugged, "just more harassment about Sasuke."

Iruka's brow knotted slightly, "Why do you suppose your subconscious is so focused on Sasuke?"

Naruto's tongue swiped across his lips, "I guess because..." I love him, "there are aspects of our relationship that I have a hard time accepting. Kyuubi forces me to confront those ideas."

Iruka's gaze was just short of piercing as he watched the blond respond. While he did answer the question, he managed to avoid revealing anything. The brunet sighed, as interesting as that line of questioning may be it was unfortunately irrelevant – he needed to move on.

"Anything else? Trance states or lost time?" Iruka asked as he jotted down more notes.

"I really don't remember," Naruto pursed his lips and looked up as he tried to recall the events of the past weekend, "I guess there were a few times where I would find myself someplace and not know how or when I got there. It was like I woke up someplace different than I fell asleep... except I never fell asleep."

Iruka nodded, "That is not uncommon at all, especially if you are doing something routine like going to dinner or watching TV."

"I have a question," Jiraiya stated suddenly. All eyes turned to him, "How long have you been in love with Sasuke?"

Naruto stiffened in his seat as if a volt of electricity had shot through him. Iruka whipped his head to the side, "That is not appropriate," he turned back to the blond, "you don't have to answer that."

"On the contrary," Jiraiya turned to the grad student, "if my assumptions are correct, Naruto's realization of his feelings are a direct result of the experiments." The older man turned back to Naruto and smiled, "Am I right?"

Wide sapphire eyes shot back and forth between the two men and Naruto's hand shot up to the back of his head, scratching nervously, "I-I..." he looked down, studying his shoelaces intently before bringing his eyes back up, "I don't really know... I probably always loved him."

Jiraiya sat back in his chair, smirking with satisfaction, "So what changed?"

Naruto pursed his lips in thought, "It started with the hypnotism I suppose. Sasuke began to make advances and I didn't stop him. And then the sweat lodge with Kyuubi... I really couldn't deny it after that."

"Naruto," Iruka spoke softly, "would you say that your change in perspective was a direct result of these experiments?"

The blond furrowed his brow, "No. I mean... I didn't really change my perspective, I gained a new understanding. I always felt something strong, I just didn't know the extent of it until now."

Iruka smiled, "It sounds like you have learned a lot about yourself."

Naruto smirked, "You have no idea."

Naruto smiled as the door to the stairwell opened, he stopped and leaned against the wall as Sasuke crossed the threshold. Sasuke offered a small smirk as he sauntered up to the blond. A pale hand found its way to Naruto's chest before traveling up. Fingers ghosted over the column of his neck before coming to rest in golden locks.

Naruto's smile was consumed by pale lips, he tilted his head and deepened the kiss. Sasuke's tongue gently slid against Naruto's, eliciting a moan from the blond. Begrudgingly, Naruto pulled back; he smiled again as Sasuke shook his head and pursued him further, tongue forcefully infiltrating his mouth.

He pushed the raven-haired boy back, "Nice to see you too."

"Hn." Sasuke responded with hazy eyes.

Naruto moved off the wall and toward the door, "Good luck up there," he offered a contrite smile, "they know about us."

A dark eyebrow arched, "Really?"

"Try to behave," the blond replied dryly.

"So Sasuke..." Iruka began.

"Hn."

"...tell us about your sleep deprivation experience."

"Those were quite possibly the best and strangest three days of my life," the pale boy replied with a smirk.

Iruka and Jiraiya exchanged a quick glance before the brunet continued, "Care to expand?"

Sasuke shrugged, "You saw our videos. Why don't you stop being coy and ask what you want to know?"

Iruka pursed his lips, his eyes taking on a devious glint that seemed very foreign in the soft brown hues, "Let's start with the synesthesia. You said at one point you saw sound. Please describe it."

Sasuke's face remained placid, though his pulse quickened with the memory, "Naruto appeared to glow and when he spoke sparks came out."

"Yes, that is what you said before," Iruka's tone was teasing.

"What more do you want to know?" Sasuke retorted dryly.

Iruka smiled, "I'm looking for... details."

Midnight eyes chilled a few degrees as Sasuke stared defiantly at the brunet, "If you must know..." his gaze flitted between the two men across from him, "we were fucking." Sasuke smirked at the wide eyed grad student, "He glowed red and as I plowed him harder it grew brighter and when he came it was like a geyser of light... Any other questions?"

Jiraiya appeared thoroughly amused, "My, my Sasuke. You really were able to find ways to entertain yourself."

Sasuke's smirk grew, "Oh, we kept ourselves very entertained."

Iruka recomposed himself and cleared his throat, "Did you have any other hallucinatory episodes?"

Sasuke shook his head, "No," he chuckled darkly, "I thought I did, but it turns out some nightmares are real."

The grad student took pause, "You had difficulty distinguishing between reality and hallucinations?"

"I think it was more disbelief than confusion," Sasuke replied coolly.

"Given your experiences," Jiraiya began and dark eyes turned to him, "do you believe what you have developed with Naruto to be genuine?"

Sasuke's onyx eyes slitted, "What are you implying?"

Jiraiya raised his hands in defense, "Sasuke, I am not implying anything. I am just curious if you believe the sincerity of your emotions... or Naruto's."

"There is not a single doubt in my mind," Sasuke's icy tone cut through the space between them, "that what we have is real."

"Hey Sas–" Naruto was cut off as he was pushed roughly into the wall. He looked around the empty hallway before returning his eyes to Sasuke's. With a tint of concern in his voice he continued, "What's up?"

Pitch black eyes searched Naruto's wide azure obs. Fucking Jiraiya. Sasuke had never once doubted Naruto, but now the idea was festering in his mind. But as he peered into Naruto's eyes he found his uncertainty waning. Those sapphire eyes, flecked with darker hues that added dimension and depth, shimmered as they stared back. There was no doubt, fear or pretense.

"Naruto," Sasuke brought his hands up to cup Naruto's jaw, "I love you."

Those cobalt eyes blinked away their confusion and softened, filling with warmth. Naruto brought his hands up and grip Sasuke's wrists, "I love you too."

Sasuke visibly relaxed, he dropped his head to Naruto's shoulder and sighed. Still slightly uncertain exactly what was happening, Naruto wrapped his arms around Sasuke and gently rubbed the strong back. He felt as Sasuke took a deep breath before straightening and taking a step back.

Naruto cocked his head, "Is everything okay?"

Sasuke's posture relaxed, "Everything is perfect."
