Author's Notes: Hello again! Second installment of Entanglement. Things are just getting steamy all of a sudden. This is a warning for m/m action in this chapter (already?!), so if you do not want to read an m/m scene, please skip that part in the chapter or skip the chapter itself! Thanks for reading, always.

"Dobe," Sasuke called out, earning no response from the blonde nuisance. Naruto scratched his head absentmindedly, as if he were unsure as to whether he heard his name being called. Sasuke leaned against his desk, facing toward the front of the room where Naruto sat. He called Naruto again, using his childhood nickname for the unintelligent blonde. Yet again there was no response, but a scritch scritch scratching of Naruto's head again. Naruto vainly looked around himself in attempt to find the match to the voice.

"Naruto." The voice beside Sasuke called out Naruto's name. In record speed, Naruto turned around to look at Sai. He grinned at the taller raven haired boy with his trademark "village idiot" smile. Sasuke tsk'd as he saw Naruto's quick recognition to Sai's voice, but not his. He tapped his desk in annoyance, wondering if Naruto had forgotten his voice or something along the lines of that. How mortifying, if his best friend had really forgotten all about him. All those years invested in a "good friendship", or so he thought, down the drain...

"Sasuke was calling you," Sai glanced at Sasuke, then Naruto, who was still facing backwards. That was quite kind of him, Sasuke thought as he peered over slyly at Sai, who returned to drawing in his textbook. Although he would never admit it. Naruto glanced from Sasuke to Sai, smiling to himself as he saw slight interaction between the two males. It seemed as though despite that they had just recently met, they were quickly getting closer. Naruto giggled and grinned sheepishly at Sasuke, earning a questionable stare from the Uchiha. What was the idiot grinning about now?

"Let's go get changed for PE before lunch." Sasuke called out, getting out of his seat to go downstairs to grab his school-issued black PE bag from his locker.

"Hey, Sai, let's go!" Naruto slung his arms around Sai on the way out of the classroom. Sasuke let the smile fall from his face, only to recover it in a quick second before his grimace was spotted. Sai let himself be dragged out of the classroom by Naruto. He still couldn't tell if his heart was beating irregularly due to Naruto or if he had a serious health issue...

Sasuke sighed as he put his hands in his pockets and walked down the stairs to the first floor, making sure to look cool even though he was simply walking. Of course Sai would be invited to change together. The four of them were all supposedly friends now. Sasuke was not sure of how pleased he was to see this rapid development. Sasuke couldn't help but to think "the more the better" was not the case in his close friendships. The easily irritated Uchiha had enough on his hands with Sakura and Naruto without Sai barging in.

Naruto successfully broke Sasuke's silent chain of thought by swinging his left arm around Sasuke's neck, Sai on the other side under Naruto's right arm. Then, Naruto proceeded to whistle cheerfully in both the boys' ears. This earned a grimace from Sasuke. Sai glanced over at Sasuke as he grimaced and smiled slightly, and began whistling in harmony with Naruto. To Sai, Sasuke was intriguing. He was sure that Sasuke actually enjoyed Naruto's company and wished to be even closer to him, but hid behind a facade, pretending that he didn't give two shits about his blonde haired best friend. Which was absolutely ridiculous to him, and Sai could not comprehend Sasuke's character whatsoever. Why not just be honest to yourself and the ones important to you? Maybe Sai's personal issue was his tactless honesty that never failed to earn a curious, scrunched up expression on his friend's face. At least whatever that was on Sai's mind was also printed across his forehead for everyone to read, despite the lack of readability in his facial expressions. And Naruto, on the other hand, was obviously an open book in every aspect.

However as of late, Sai had found that Naruto's ability to lie and cover up his feelings had been improving to his immense dislike. Naruto's openness had been a quality that Sai had admired, even to the point of striving to shadow. Whatever Naruto possibly had to hide from his friends, Sai didn't like it. In fact, he despised it, and deep down, he could feel his insides bubbling even with the thought of it. These feelings were all new to Sai, and it was too difficult to decipher the deep-seated, inner feelings that would occasionally arise with the ruminations of his best friend.

Sai was much too ignorant to Naruto's feelings. Even when Naruto attempted to hide away his sentiments regarding a certain person, it was completely transparent. Only Sai could not detect these signals that Naruto sent to Sakura. Around her, Naruto overly exerted himself. He would always try to suppress his immaturity, but apparently failed to do so, which would earn questionable stares from Sakura. Not only was his immaturity (attempted to be) hidden, but Naruto would frequently boast about his endeavors. How this was all unbeknownst to Sai was the main question. He was normally known for his cleverness and academic success, but when it came to others' feelings and his own, Sai was utterly lost. And in a sense, Sai's ignorance was a blessing to himself, Naruto, and their teetering friendship.

When Sakura called for Sasuke, Naruto's head immediately turned in the direction the voice came from. Sasuke nonchalantly turned his head to glance at her without even bothering to respond.

"Sakura! We're going to go change, don't peek at our six-packs, okay?" Naruto grinned and untangled himself from the two raven-haired boys. This earned an eye roll and the crossing of arms from Sakura.

"Please, Naruto, like I would even look at your flab pack." She turned on her heels and began to walk in the opposite direction. Sai and Sasuke glanced at each other, shrugging. Naruto's bottom lip protruded offensively, his whole body drooping from the blunt rejection. To his surprise, Sakura turned around again.

"But I wouldn't mind stealing at peek at Sasuke!" Sakura attempted to throw Sasuke her most enticing smile, but his back was already turned and walking away. To Sakura's disappointment, Naruto had been the only one to catch this seduction, whose jaw instinctively dropped. Sai hurriedly put Naruto's jaw back into place and dragged him to the lockers. They grabbed their bags, and on their way back into class, Naruto animatedly told another story while waving his PE bag around dangerously. Sai routinely laughed in amusement at Naruto's actions, and Sasuke managed to let out a pitiful chuckle.

Sasuke slid the white classroom door open to find no one inside. Naruto scratched his head in confusion.

"It's the ramen special set in the cafeteria today." Sai responded to Naruto's silent confusion. Naruto's eyes abruptly brightened.

"Well what are we waiting for? I have to go before it sells out!" Naruto stripped as soon as the door was shut behind him. He threw his white shirt on his desk and left his pants pooled around his ankles in haste. Sai and Sasuke both stared at the boy in amazement. The love of ramen Naruto had was immense and apparently, unable to ever be filled. Naruto threw his white gym shirt over his head whilst simultaneously kicking his shoes and school pants off. Sasuke and Sai could only stare silently as Naruto pulled his PE shorts on and slipped into his shoes. Without a goodbye, Naruto speedily ran out the classroom, leaving Sai and Sasuke speechless and staring at the empty space Naruto left behind. They both slowly looked at each other in unison, unable to utter a single word for minutes to pass.

Finally, Sasuke broke the silence.

"What an idiot..." He shook his head and placed his gym bag on his desk. Sai did the same, nodding silently in acknowledgement.

An eerie silence clouded the classroom. Sai looked away as he opened his bag to change, and Sasuke imitated his exact actions. Without Naruto or Sakura, it definitely seemed awkward, especially as they had just met today and were taking their clothes off in front of each other on top of that. Sai glanced at Sasuke's body as he was the first to take off an article of clothing. Sasuke lifted his shirt over his head captivatingly without bothering to unbutton the shirt. He turned to look at Sai, who was staring at him blatantly. Sasuke blushed a deep shade of red he didn't even know he could make.

"W-what?" He looked fixedly into Sai's eyes. To Sasuke's shock and embarrassment, Sai gave him a once over, looking up and down at Sasuke's body. Almost contentedly, Sai smiled and replied, nothing. Sasuke looked away quickly and slowly began to take off his pants, to leave him in his dark grey Calvin Klein boxer briefs. Sasuke had to look good regardless of what his actions were. At this point, Sai had begun to take off his own pants. Sasuke couldn't help but to sneak a peek at Sai's body. His eyes ran up Sai's entire frame, scanning each defined muscle and curve that 18 year-old Sai had.

Sai glanced at Sasuke, who had been gazing at his body silently for a while now. He smiled slightly.

"Are you a virgin?" Sai managed to break the silence, albeit quite untactfully. Sasuke turned flushed a deep red in response. He could feel his flush creep to the tips of his ears, making them hot with embarrassment.

Sasuke felt himself die a little inside. "H-huh?" He grimaced, "What are you talking about?" Sasuke mentally reproached himself. Oh god, why did I stutter?

"You're just staring at me as if you've never seen a guy without clothes on before," Sai smirked almost uncharacteristically, "Or is it because I'm just that good-looking?"

"Don't kid yourself." Sasuke muttered under his breath, as he reached into his bag to grab his gym shorts. Who was Sai trying to fool with his fake bravado? The alpha male here was supposed to be Sasuke. He was much more popular than Sai, better looking, smarter, and superior in every way… Or so Sasuke assumed. There was hardly ever anyone who was more popular than Sasuke at school, and he prided himself on that fact alone.

"Just so you know, I'm not a virgin, okay?" Sasuke felt the sudden urge to assure his new friend of his sexual orientation and prowess, "And I'm not gay either." He turned away again, embarrassed that he had to tell Sai these things with his own mouth.

Sai shrugged as he put on his gym shorts and turned away to pack up his PE bag. Not that he actually cared whether Sasuke was a virgin or not. And what was so wrong about being gay anyways? Sai could see no problem with it. He opened his mouth to respond, but proceeded to shut his mouth as he saw the tips of Sasuke's ears still flushed in distress. Sai felt a small smile tug on the corners of his lips.

"Are you sure you're not gay?" Sai smirked as he approached the smaller male. He placed his left hand on Sasuke's desk and proceeded to lean closer to Sasuke's turned back.

Sasuke flinched as he felt the sudden warmth emitting from Sai's unfamiliar body on his back. "How could I possibly be gay?" Sasuke managed to spit out. He could feel his whole body ignite with what felt to be a mixture of embarrassment and an unknown, hot feeling. Sasuke shivered as he felt Sai touch the back of his neck softly.

"Is there something wrong with that?" Sai responded as he traced his fingers down Sasuke's bare neck. At this point, Sasuke felt as though his whole body would turn a vivid red from Sai's touch. Sasuke could feel his own hands tremble with excitement. But he couldn't go on with this, and he knew this all too well himself.

"Stop." He commanded, turning around to give Sai the dirtiest look he could possibly muster up in the moment. Sasuke's face was still flushed with both excitement and disgust as he glared at Sai and quickly spun on his heels, leaving Sai all by himself.

Sai stood awkwardly in the classroom, the air feeling heavier than Sai had ever felt it. He didn't feel any form of embarrassment, but rather felt intrigued by Sasuke's response. In some ways, Sai found himself feeling quite pleased by the outcome of his actions.

And as typical in fabricated stories such as this one, the school bell signaling the end of lunch-time rang with impeccable timing. Sai quickly pulled the rest of his gym clothes on. Breaking Sai's lonesome but nevertheless slightly awkward silence, Sasuke surprised him by storming back into class.

"Don't. Tell. Anyone." He walked up to Sai, their faces losing more and more distance. Sai, nor Sasuke knew what he was thinking when he did what he did. Sai nodded and smiled in response, succeeding in irritating Sasuke.

"Yes, of course."

They were interrupted by the chatter of classmates, coming closer to the classroom. Sasuke turned around abruptly and sat himself down onto his seat. He put his head down on the desk and held his breath. His excitement and thoughtlessness had gotten the better of him. Sasuke groaned silently as he buried his face into his arms, feeling hot once again from thinking about Sai and how close he was, how gently his fingers brushed down his neck…

Sai let a small smile trace his lips as he sat down across from Sasuke. He leaned over and breathed into Sasuke's exposed ear.

"You're amusing, Sasuke-kun."

Sasuke jolted in his seat but did not raise his head to look at Sai. Sasuke could feel his ears redden where Sai murmured into them, but Sai did not seem to notice. His eyes were on Naruto, who pranced happily into class with Sakura, just like his usual self. No one would know of what happened between Sasuke and himself.
