Note: Uh, I post little personal updates about how chapters are going on my RP tumblr Bakaomine. I also take one-shot requests on it—I will post them on this FF account, too—but they take me a while to write. I apologize if this chapter is difficult to follow and for any mistakes!

Chapter 4 – Doubts and Suspicions.

The day it started, the first thing Aomine had told Kise was, "You're only asking for trouble."

And he was. He knew very well what he was getting himself into, and he'd brought it upon himself.

Kise could vaguely remember the moment things went from shared looks across the gym and locker room, to touching when no one was around; an unbearable desire that grew larger and larger the longer it went unspoken of during their days at Teikou. Little winks and lick of the lips across the room to one another, making the other squirm and cross their legs in class. There was an undeniable lust—a craving for one another they swept under the rug, neither ever daring to acknowledge it until, one day, the two ran each other during the summer break they graduated from middle school.

Aomine was walking home from Maji's, or at least , for as long as he could, when he bumped into Kise, who'd been in the area on the way back from a photo shoot in the rain. Like any normal person, Aomine ran into the nearest bus shelter to take cover as it began to pour heavily, and rummaged through his pockets and back pack for any spare change or his bus pass. Even for someone as uncaring as him, he didn't want to return home soaked and risk catching a cold.

Hah. A cold—It would have been just what he needed to start off the summer with. To be cooped up, sick and delirious when he should've been living it up before high school started? Now, that wasn't appealing at all. Not to mention the thought of having Momoi sleep over just to take care of him sounded like far too much work on his part than it would have been on her part. He always did wonder how he became friends with someone as high-maintenance as her.

As he waited for the rain to stop or calm down enough for him to run through, he noticed a dark limo pull onto the side of the road in front of the shelter. Looking through the clear glass barrier that shielded him from the puddle the expensive car drove straight into, Aomine flinching ever so slightly as the water splashed upwards against the glass, he peered into the tinted car window, his dark eyes squinting. He couldn't see a damned thing until the dirty puddle water slid down the glass and the dark screen rolled down to reveal a familiar face.

Sitting there, decked out in pricey clothes, honey eyes glittering in such gloomy weather, Kise called Aomine over as he waved. Rising a brow, he stayed in place, refusing to budge the slightest inch. If he had to tell him something, Aomine was sure he could have heard it from inside the shelter. Not to mention no one else seemed to be around if the blonde planned on revealing some sort of secret, and Aomine wasn't surprised. Only an idiot would come outside after it started raining.

Aomine shook his head and watched as the blonde's lower lip jutted out in a pout. "Come here!"

"Why? I can here you perfectly fine from here." Countered Aomine.

"Awh, c'mon, Aominecchi, come here!" But still, Kise called to him. He motioned for him with a long finger to come near, and Aomine shook his head once more.

"What is it?" Asked Aomine, his voice loud enough for Kise to hear him through the rain and distance, the sound of pouring rain thick and noisy. "Did you need something?"

Kise chuckled lightly. "More like you need something—A ride. Where you headed?"

—-—

Aomine and Kise had completely forgotten about the tour around Touou; instead opting to make up the time away from each other in the nurse's office. Because Aomine often skipped classes, and he knew the nurse's schedule like the back of his hand. Good thing for him; right now was her break, and she usually spent it in the staff room on the first floor with the other teachers.

As rays of sun flooded through the thin white blinds, there was the low humming of the lights and eerie emptiness of the room and small beds. Aomine found it calming and relaxing. He'd spent so much time in the nurse's office during her breaks; he had found comfort in those familiar white walls that encase him and Kise.

"Hnn… It's been a while, ne?" Aomine bit his lip with a satisfied sigh, Kise humming in agreement as he shifts a little on his knees, the tile floor harsh and uncomfortable against them.

"Ne, Aominecchi… My knees hurt."

"Huh, I thought you'd be used to this by now."

"Eh? How rude!"

Classes were still in session. Some students were studying hard, while others slept behind their books, pretending to listen to whatever drabble fell from their teacher's mouths. It was another half an hour before lunch, anyway, and that called for bearing with it in whatever way possible until the bell went off.

Only a few students carrying heavy books and boxes were in the otherwise empty hall, bringing back the things their teachers had requested obediently, as they chatted to each other animatedly. Quietly, the sounds of lewd slurping and low groaning can almost be heard as they made their way down the wall. Momoi thought she heard Aomine's voice, but shook her head as she adjusted the textbooks in her arms. It couldn't be him—His class was all the way on the other end of the school.

"No, it can't be." She giggled to herself lightly as she continues her way back to class with her peers.

She must be hearing things.

"Right?"

Meanwhile, running his hands through Kise's hair, Aomine gave an encouraging tug, pulling on the lightly colored strands harshly. Aomine licked his lips and gave a nod of approval as Kise dragged his tongue from the base to the tip of the former's cock, the unique taste of precum on his taste buds and a playful moan falling from his lips. Aomine shuddered and rolled his hips into Kise's awaiting mouth impatiently. He couldn't wait or sit through the model's teasing—He needed release, and he needed it now.

Aomine could hear the far off ticking of the clock hanging above the banged up white door, its pace even and steady like the bobbing of Kise's head. How long have they been in there? Aomine wasn't even sure. They had ditched the tour the moment they came across the nurse's office on the other side of the school. All it took were a few suggestive looks and a hand around Kise's hips that brought the blonde practically begging to be taken. It was almost funny how a couple of sex-less days could make Kise want him this much and vice versa.

Opening his eyes, Aomine peered down at Kise, whose bright honeys stared back wantonly, a sinful little gleam telling him he wanted this just as much as Aomine did. Kise forced the cock past his mouth and into his throat where he proceeded to moan, the vibrations sending a shiver down Aomine's spine and left his hips bucking. The blonde gagged and the sound aroused Aomine further, thrusting his hips upward as the hand threaded into the blonde hair kept his head in place.

Kise tried to keep up, tears forming in his eyes from all the concentration and sudden movement on Aomine's part. He opened his mouth wider and hollowed his cheeks, letting the cock slide in and out freely and easily, while he played with his own erection. Kise slid his hand up and down, giving rough and gentle tugs the way he knew Aomine would, his face turning a dark red as he convinced himself; it's not his hand, it's Aomine's.

Kise's practically choked after a particularly deep thrust, his eyes widening, his pumping growing quicker and harsher. The sound of Kise gagging and struggling was delicious and Aomine could no longer help himself as he pulled out and released. The blonde pumped Aomine dry onto his face, and himself onto the cold floor, pearly liquid rolling down the corners of Kise's mouth and down his chin as he gasped for air. He stuck his tongue out and began to lap at Aomine's seed for show, his face growing redder and more flustered by the second.

Aomine bit his lip with a low, satisfied hum and Kise grinned up at him. "So? How was that?"

Reaching down, Aomine cupped his cheek roughly and smeared the cum on Kise's cheek across his soft skin with a smirk. "What do you think?"

As Kise laughs, Aomine moves him onto the bed. Kise's uniform is practically torn off, flying across the room and onto the floor. Loosening his necktie, Aomine unbuttoned his own shirt and slipped off his black school jacket. Things were getting hot, and so was he. He was still in the mood, and Kise didn't seem to be putting up any protests. Spreading Kise's legs, he shoved his fingers into the teen's mouth with a smirk, who took the long digits with a welcoming hum.

Only an idiot wouldn't know what came next.

—-—

They rode in absolute silence. The radio played softly in the background, the sound of rain hitting the pavement and exterior of the limo drowning out the pop-ish beat as it grew heavier and heavier. Aomine ran a hand through his wet hair, as he looked out the window. Kise was glad he had accepted the ride instead of wait outside. It looked horrible—Any longer, and Kise was sure he would have surely been washed away.

Kise watched from his seat across from Aomine as the boy sat in his street clothes uncomfortably, squirming against the leather surface of his seat in an attempt to find a pleasant position. His backpack was dropped onto the aisle between their opposing seats beside Kise's and the two shared a look. Kise smiled over at him, his eyes bright and energetic as usual, and his expression welcoming. Aomine didn't return it, instead keeping his face lax and stoic. It was a little strange. The first time he'd ever met Aomine, he was smiling and Kise was the one looking bored. Funny how things could change like that, huh?

It was just during one of their games where he'd begun losing that sort of excitement in his dark eyes, but Aomine would always be Aomine, and they would always be friends. Leaning into his seat comfortably, he entertained the thought a little; Kise liked the thought of always having Aomine around, his friendship dear and precious. However, he'd been starting to see Aomine in a different sort of light.

Kise took the chance as Aomine turned to look out the window to glance over at him through his peripheral and admire the boy's choice of clothes. Truthfully, he'd never seen Aomine out of their Teikou uniform before, and it never occurred to him that he actually owned other clothes and had his own style and preference until then. Dressed in a pair of faded black jeans, his favorite dark Nikes, and a regular t-shirt, Kise came to the conclusion that, while it personally wasn't what he would have chosen to wear, he liked the way it suited him. It was plain and simple, just like Aomine.

"He looks really nicer when he's dressed as himself. Aominecchi's actually really attractive…" He thought to himself, eyes trailing from Aomine's pants to his shirt, the wet fabric clinging to his every line as he struggled to find a comfortable way to sit. The model caught himself staring a little longer than he should be, and his eyes dart downward towards the floor, his brows furrowed. He felt a little guilty because they were just friends, and he shouldn't be thinking like that.

But he couldn't help it—the way he felt—and apparently neither did Aomine, who reached over to place a hand on the blonde's thigh. His touch was warm despite having been stuck out in the poor weather, and his fingers dip between his thighs, groping between Kise's legs as his face went pink and he shuddered.

"I saw you staring at me." He said, chuckling knowingly. Kise blushed in embarrassment. Aomine's wandering hand, that drifted from the inside of his thighs from his knee, upward, did nothing to help his already heated cheeks. With Aomine's thumb moving in soft little swipes, while his long fingers groped and squeezed, making Kise's knees close, trapping the other boy's hand, Aomine said, "Oi, my hand—It's stuck."

"S-Sorry…" Kise mumbled shyly as he spread his legs to release the boy, but, to his surprise, Aomine used this to his advantage to find a place on his knees between the blonde's legs. He towered over the blonde in his low seat with his back slouched forwards, careful not to bump his head against the roof of the car. Kise's already flushed cheeks flourished into an even fiercer blush, reaching as far as his neck as he gulped nervously; it's things like this that mess with his head and his ever-changing, but equally confusing feelings. "A-Aominecchi?"

"Mm…?" Said boy's hand came to rest on the seat beside Kise's thighs as he leaned even closer, his lips a mere inch from the blonde's. Kise was so sure if he got any closer, he would be able to hear the nervous thudding of his heart against his chest.

"Ne, your face is all red." Aomine stated flatly, moving away slightly and reaching up to poke the model's cheek.

"N-No, you don't s-say." Kise stuttered awkwardly, too focused on the close proximity than his words and the sound of a belt buckle being undone. "Aominecchi, what are you doing—"

"Don't play innocent." The power forward cut in, his low voice effectively silencing Kise, who squirmed around in his seat trying to replace the distance between them; this only proved to be futile as the further away Kise moved, the closer Aomine advanced, an animal slowly closing in on its prey. His hand trailed from the boy's warm cheek, down to cup his chin, forcing their eyes to meet when Kise turned his head to look away timidly. "Oi, don't play shy with me now."

"W-What do you mean—"

"You started it. We've touched and done all this stuff in the locker room already, what makes this any different? We aren't even doing anything." The question leaves Kise inquisitive. He had done a little more than he was willing to admit to Aomine's face; even things he never thought he would have been able to do. The memories and thoughts made him shudder under the power forward. The almost playful expression in Aomine's voice coupled with the way his hand dropped to run over Kise's shirt, tracing over his muscles through the fabric, moving teasingly and feather-light as he went over Kise's nipples, making him hiss through gritted teeth, to the end of his top. Aomine tugged it upwards to reveal the delicious pale skin of Kise's abs and toned torso.

Kise gulped, suddenly feeling more exposed to him than he ever had in the showers at school. "What are you—Okay, y-yeah, I guess, but—"

"But what?" Kise had never seen or heard Aomine this impatient before, all traces of playfulness in his voice gone. The way Aomine looked at him expectantly, and the needy expression in his voice as if begging for more—It caught Kise off guard. "I know you want me as much as I want you."

"Aominecchi, don't say such embarrassing things!" Kise brought his index finger to his lips as if to shush him, his eyes flying towards the front of the limo. In a hushed tone, he stuttered out, "My d-driver can hear you!"

Despite this, Aomine continued, his voice louder if anything to spite Kise. "You aren't denying it."

"Er… I…"

"I'm tired of playing around with you. Do you want me or not?"

"I guess you've made a point." Kise tried masking the confusion that clouded his heart and judgement with an over-confident smirk, and a playful coo, his expression and aura changing completely. He can't let Aomine see his uncertainty. "I think I've made it apparent these past few months, haven't I?"

"Like I've said before, 'you're only asking for trouble.'" Aomine countered with a smirk of his own and he chuckled as he leaned down to press their foreheads together. "It's too late for you to back out now."

With his heart pounding erratically, Kise brought a hand up to cup Aomine's face. "Who said I want out?"

—-—

Standing up, Aomine fixed himself, wiping the sweat at his hairline with the back of his hand before he reached to tuck himself back into his boxers. He could hear the sound of Kise shifting around on the mattress as he hopped off to retrieve his clothes. He saw Kise slipping on his boxers and trousers before making his way around to the other side of the bed to fetch his shirt and blazer. The small limp in his steps made Aomine snort as he watched Kise walk over to wash his face at the sink behind the nurse's desk, splashing cold water into his face, cooling his senses. It was actually quite funny.

While Aomine zipped and button up his dark slacks, Kise stepped towards him as he turned off the faucet. His arms came to rest on Aomine's shoulders and he leaned close, his voice hushed, almost as if he were about to reveal a secret, as he smiled from ear to ear.

It had been a while since Aomine had last saw him, and he'd almost miss seeing the boy smile like that. Almost. But maybe it was because of the lewd flush that still lingered on his pale face and heavy panting through his parted lips as they both tried to calm their breathes.

"Haha, I can't believe we just did that!" He sounded surprised and secretive and breathless, doing the best he could to keep his voice low in fear of being caught. "Ne, Aominecchi, do you want to meet up later?"

Aomine smirked. "Oh? Did you want more?"

"No, not like that!" Replied Kise, shaking his head fast. "I mean, you know, hang out. Catch a movie at the mall or something?"

"This sounds like a date." Commented Aomine flatly, his hands hanging off to his sides, no intention of holding Kise as he leaned closer, almost begging for him to. But Aomine won't. He refused to.

Tilting his head, a bashful tone in his voice, Kise continued, "Maybe it could be a date? You know, if that's what you want—"

"Oh, funny. You know what I want." Aomine cut him off so sharply, Kise flinched at the finality in his voice. "All I want is physical. So, unless you plan on fucking in whatever movie theatre you have in mind, then I'm going to have to say no."

Aomine stepped back and Kise's arms fell loosely, like lifeless noodles that flopped down to his sides. Aomine didn't notice the disappointed glimmer in Kise's eyes as his attention fell toward the floor wordlessly. It was an awkward silence as Aomine crossed his arms and Kise stepped back. What could Kise have said? What could Aomine have said? There was no right thing to say, so, shuffling his feet in an awkward manner, Kise shot his eyes upward to look Aomine in the eye. His lips quirked up into an uncomfortably forced smile, a heavy weight around his heart as he said, "Well, that's okay! Maybe some other time—"

He is interrupted by the shrill noise of the lunch bell going off.

"We should probably head back now. If Katsuhara-sensei asks, I showed you around campus, got it?" Kise nodded as he followed Aomine out of the door, his shoulders slouched forward discouragingly as he slides it shut behind him.

They make it a few steps away before there is a voice from behind. "Oi, Kise?"

He looked over his shoulder. "Eh, senpai?" Kasamatsu jogged over to Kise, quickly dodging students as they step out of their classes, to inspect the boy with a hint of concern. Kise shrunk under his senpai's gaze with a gulp. "Is something the matter?"

"I should be asking you that."

"Huh?"

"You just came out of the nurse's office." Kasamatsu pointed to the little sign above the door behind him. "What kind of accident did you get yourself into? The first day hasn't even ended yet."

Kise sighed in relief. Thinking he'd gone and hurt himself was much, much better than knowing the truth, and it showed a little as the blonde's tensed shoulders eased.

"What happened to you?" Kasamatsu asked.

The model offered him a reassuring smile. It was nice seeing him worry like that; he looked up to him for a reason. "Nothing, Aominecchi was just showing me around, isn't that right?"

Kise looked behind him, and Aomine was already gone. Meanwhile, all Kasamatsu could focus on was the blonde's crumpled uniform, flustered demeanor, and breathlessness lining his every word. He furrowed his brows.

"Something's definitely up."
