A/N: Hello Everyone! This will hopefully be a longer chapter! I hope you all enjoy it. Just so you know, I honestly have no idea where this is going, it just kinda has a mind of it's own. -Anima

I OWN NOTHING! I am just borrowing Naoki and Kotoko for my own amusement.

-3K+N3-

Naoki was lost in the feel of his new secret girlfriends' hands on his bare back. 'If this is what it is like to have a girlfriend, I am only disappointed that I did not notice her sooner,' he mused blissfully.

When Kotoko finally removed her hands sometime later, he relished in the complete feeling of relaxation before sitting up in front of her still shirtless. "Thank you, Kotoko," he whispered before reaching for her and pulling her into his chest, startling slightly at having her face and hands on his bare pectoral muscles. 'Oops, forgot to redon my shirt…' he thought. "Sorry, I forgot that you still had my shirt," he explained as he released her.

"It.." she sighed deeply before whispering as she pulled backward. "It is okay, Irie-kun. Naoki noticed that her face was bright red, and the color was disappearing once again under the collar of her shirt. He felt himself smirk at the sight before taking his shirt back and pulling on before pulling her back against him so he could gently connect their lips.

"You know you can call me Naoki when we are alone, right?" he asked when he pulled back, amused at her blush and shaking head.

"I am afraid to slip up around others," she explained.

"I understand," he tells her honestly, "but I would love to hear my name spill from these lips." As he finished his statement; he swept his thumb across her bottom lip, gazing into her chocolate eyes. Leaning forward, he pressed his lips to hers once more. "Good night, Kotoko." He smiled softly before heading for the door. As he reached for the lock; he hears a soft, shy voice behind him.

"Good night, Naoki."

Naoki let out a soft groan before striding back over to the young woman quickly, grasping the back of her head with one and her lower back with the other, pulling her flush against him as he lowers his mouth to hers. When she gasps, he begins to plunder the cavern, feeling powerful when a soft mewl escapes her. At the sound he begins to feel a stirring lower on his body, forcing him to pull back from her lips, pecking her once more before fully disengaging with her, leaving them both breathless.

"Definitely only use that name when we are alone," he pants, wide eyed, shocked at his own reaction to hearing his given name from her mouth, while willing his obvious reaction to his name and having her body in his arms to fade away. "Good night," he whispers again before fleeing from her room.

When he was securely in his bed, Naoki threw his arm over his eyes. 'That girl is going to be the death of me at this rate,' he thinks, 'but what a way to go." With that last thought and a smirk, Naoki drifts off to the memory of her hands on his body and his name on her lips.

-3K+N3-

Over the course of the next couple days, Naoki barely saw Kotoko. His mother had her out of the house early in the morning, and by the time she got home and finished more of her summer homework, she was too exhausted to spend time with him. Naoki was missing the feel of her mouth on his and the feel of her in his arms.

'I am glad we are going to the water park tomorrow,' he mused that night as he laid in bed, staring at the ceiling. 'I need time with her… Yuuki should be willing to keep my secrets."

The next morning, his mother stormed into his room after a swift knock. Yuuki was at his desk working while Naoki was reclined on his bed reading a book. 'Here we go,' he smirked internally.

"Oni-chan," his mother began in her no-nonsense voice. "I need you to take Yuuki to the water park today. He has been inside too much this summer."

"But," Yuuki began to protest.

"Why do I have to take him?" Naoki interrupted, shooting Yuuki a look that caused the younger boy to raise his eyebrow.

"Because I have to do some chores around here and run some errands," his mother explained, trying to hide her scheming look.

"Fine," he agreed, knowing it was no use to argue, and that he was secretly getting his way. Ignoring her squeal, he grabbed his board shorts and a tank top from his closet, hearing the door close behind her.

"Why do we have to go?" Yuuki whined.

"Because Aihara is going with her friends, and I am being set up to see her in a skimpy bikini," he explained as he allowed his head to lull back and take in his younger brother who had just finished pulling on his own tank top, board shorts already in place.

"So why did you agree, Oni-chan?" he asked confused.

"I will explain on the way," he chuckled. "Too many ears in this house." About 30 minutes later, they were on their way to the water park with snacks, drinks, and towels in tow.

"So…?" Yuuki prompted about 15 minutes into their walk, breaking him out of his thoughts of a certain coppered haired girl. Looking around, he did not see their mother, so he began to explain.

"Oh, right." He replies. "Can you keep a secret from everyone else in the house?" Seeing his brother nod, and the interest in his eyes, Naoki cleared his throat before continuing. "So I like her… Like I asked to her be my secret girlfriend, but I have issues with… maintaining a respectable distance in her presence."

Seeing the shocked look on Yuuki's face, he paused. When his brother physically shook himself out of his stupor, he began to explain more. "I do not know why I am so drawn to her, but I enjoy my time with her. Okaa-san has monopolized her times the last few days, so I know I will be unable to refrain from interacting with her today. So that is why I am telling you ahead of time."

"But Oni-chan," he started slowly, confusing dripping from his tone. "She is baka! How can you care for her?"

"She actually is not baka," he replied easily. "She just learns a little slower, but once she grasps the concept, she never forgets it." Seeing his younger brothers' skeptical look he smirked. "I am still tutoring her because it gives us uninterrupted time alone together." 'In a locked bedroom,' he added internally, his smirk getting bigger.

"Are you sure?" Yuuki asked him. Naoki just nodded. "Are you happy?" He flashed his brother a small smile, his eyes lighting up with thoughts of the girl. "Okay, Oni-chan." Yuuki said in shock at seeing the sappy look on his older brothers' face. "I will keep your secret. I can still tease her, right?" Naoki just laughed and agreed before they stepped up to pay for their tickets.

As they waled towards the pool, Naoki heard a comment that set his blood to boiling.

"Kotoko-chan," the black-haired menaces' voice rang out clearly. "You look amazing in that bikini. Kin-chan thinks that you should cover up so no one else sees his.. I mean, sees you like that."

Throwing his back and tank top down at an unoccupied set of chairs, Naoki stormed over to where the object of his affection and her friends were. He briefly registered Yuuki trailing behind him. Stopping just shy of Kotoko's back, Naoki gazed at the other teen boy with a hard glint in his eye. Kotoko leaned backwards away from the other boy, her arms crossing in front of her chest and a blush on her cheeks, causing her to collide softly with his chest.

Naoki's breath caught as her mostly bare back came into contact with his bare chest. He gazed down at her as she jolted away from him, bowing deeply with her eyes closed in an apology. "BAKA," he drawled, delighting in the sight of her quickly straitening up as her eyes snapped open and her hands dropped to her sides.

"Nao…" she whispered before catching herself. Naoki closed his eyes while sharply drawing in a breath to control himself before looking at her again. "Irie-kun," she stammered. "It is a surprise to see you here."

Naoki noticed her blush spread as he took in the dark blue bikini his mother had forced her into. 'The red covers the entire upper part of her chest,' he observed with a small groan. "Aihara," he smirked, before flicking his eyes up to the trio of people behind her. "Ikezawa, Komori, Ishikawa." He greeted them each before his eyes returned to Kotoko. "Nice suit," he smirked as he watched her blush burn across her chest once more.

"Hey, Irie-demon!" Ikezawa scowled as he attempted to step between them. Naoki grabbed Kotoko's arm, pulling her back against his chest, holding her in place by an arm across her collar bone.

"DO NOT TOUCH HER," he snarled, shocking himself and everyone around him, besides his brother who was smirking at him.

"You DEMON!" the other boy screeched. "UNHAND HER THIS INSTANT!"

"I do not think that Onee-chan wants Oni-chan to release her," Yuuki smirked wider, surprising Naoki with his acceptance of the girl by him addressing her as his big sister. Kotoko's head snapped to Yuuki at the title, tears in her eyes, causing Naoki to smile fondly at her.

"Onee-chan?" her friends asked confused before they noticed how comfortable she seemed in his arms despite the fact that they were both barely clothed.

"Irie-kun," the girl in his arms whispered as she touched his wrist. "I am okay." He released her but grasped her hand to keep her next to him.

"Fancy seeing you here," he smirked, squeezing her hand gently, his smirk growing as she blushed and tucked her hair behind her ear with a soft smile.

"Wait.." Satomi said suddenly. "Are you two dating?"

"What?!" Kotoko exclaimed. "NO!"

"Yes," Naoki replied at the same time, wrapping his arm around her shoulders. "We are dating."

"Irie-kun," she questioned shyly while her friends gaped in shock at the development.

"It is not my fault," he whispered to her. "Okaa-san has kept you busy and we have had no time together the last few days. There is no way I am keeping my hands to myself with you looking like that."

"But Yuuki-kun," she replied with a deep red blush staining her skin.

"Will keep Oni-chan and Onee-chan's secret," the younger boy responded.

"Secret?" Jinko asked as the trio finally recovered from their shock.

"Are you ashamed of her?" Ikezawa growled.

"Of course not," Naoki drawled. "Would I do this if I was?" He then leaned down to connect his lips to Kotoko's, relishing in the feel of kissing her again after going a few days without. When she gasped against his mouth, he pulled back and gently nipped her lip, soothing the spot with his tongue before pulling away fully. He smirked at this trio of idiots as they impersonated fish while staring at them.

"Irie-kun," Kotoko blushed furiously before turning back to her friends. "We do not wish for Obaa-sama to force us to marry as soon as we graduate high school," she explained. "So, we are keeping it a secret. Although I guess it is only being kept from the adults in our house due to someone."

Naoki raised his eyebrow at her with a smirk. "Well, if someone had made time for use the last few nights, we would not be dealing with this."

"Really?" she asked with a smirk and raised brow of her own before gesturing to herself. Naoki took the bait and let his eyes trail slowly over her form, noting how good dark blue looks with her skip before snapping his eyes back to hers when she cleared her throat. "I think we would have still been dealing with this because someone is possessive and does not like to keep his hands to himself."

With another smirk, he leaned in to kiss her cheek. "Fair assessment," he chuckled in response, noticing that Yuuki was laughing at his reaction.

"You have spent the night together?" Jinko and Satomi screeched, causing Naoki to flinch at the sound.

"Not like that," Kotoko responded. "I am sorry, that sounds bad. We study together and spend time together during the study sessions. Lately we have just been studying.." Turning to face him, Naoki saw the remorse in her eyes. "I am sorry, Irie-kun. I did not realize that I had been ignoring you due to me being so tired." He shrugged in response with a small smile so she knew it was okay.

"It is not your fault that Okaa-san decided to try and seduce me with your swimsuit," he smirked as she flushed again.

"Oni-chan," Yuuki called to him, forcing him to break eye contact with his girl. "Can I have some ice cream?"

"Sure," he responded, squeezing her hand when he saw her pout. "Stay in the shallow end, please." He then released Kotoko's hand and walked to the stall to get an ice cream for his brother and girlfriend. As he was waiting in line; he replayed what had just taken place. 'Well, everyone at school will definitely know that she is taken,' he mused happily. Just as he was about to pay for the two cones, he overheard something that made his heart skip a beat.

"…young boy fell into the pool… almost drowned…." Some random people were saying.

"Yuuki," he panicked, racing back to the pool to see Kotoko pull his brother swiftly from the water, and beating on his back slightly to help him expel the water.

"Yuuki-kun," Naoki could her the panic in her voice. "Are you okay, Yuuki-kun?"

"I am fine," his brother grouched as he sank down beside them. "Oni-chan, where is my ice cream?"

Naoki let out a harsh laugh as he realized that his brother did not fully grasp the danger he was just in. Pulling Kotoko into his arms, he kissed the top of her head, squeezing her tightly. "Thank you so much, Kotoko," he whispered. "I do not know what I would have done if Yuuki was hurt." He held her tighter and turned her face against his neck as he felt her begin to break down as the adrenaline began to wear off.

"I will get you ice cream on the way home," he told his brother as he held his girlfriend and waited for her to calm down. "I think we have all had enough excitement at the moment." When Kotoko was calmer, he pulled back and wiped the tears from her facing, leaning forward to kiss her forehead gently. "How about we ride some of these water slides?"

The group of teens and Yuuki then began a fun filled day of riding the water slides. During the last ride of the day, something unexpected happened that caused Naoki to once again almost have a heart attack. He heard Kotoko screaming his name as she hit the water. He waited anxiously for her to resurface for five seconds before diving in after her. When he reached her, he noticed the pained look on her face.

Naoki yanked her out of the water and hauled her from the pool. "Kotoko," he panted, worried. "Are you okay?"

"It hurts," she whined, grasping her foot.

Naoki began to relax as he figured out that she was experiencing a really bad muscle cramp that caused her leg to seize up. He began lightly massaging the area to get her feeling better. "Better?" he asked gently after a few minutes.

"Much," she replied with a blush. "Thank you."

Leaning over, he gave her a quick kiss. "Please do not scare me like that again."

"Okay," she promised.

All in all, Naoki had never had more fun day at a water park. He could not wait to get home and spend some time with her when it was just the two of them again. 'Hopefully we can spend some time alone before we start back up for school,' he wished to himself.
