When Hinata Shoyo is bored and Kenma is just gaming, they decide to level up.

0o0o0o

"Hey, Kenma!" Hinata Shoyo poked her head in Kenma's room. "Look what I got!"

Pulling out the item from behind her, she held out the new game that was just released yesterday. It had been hard for her to get a hold of it, especially since it was a sequel from a very popular game. She looked in every store and online, but they were sold out everywhere. It wasn't until she overheard a classmate trying to sell of extra copy of his that she jumped at the chance and claimed it. Needless to say, she was really excited to have found the game.

Kozume Kenma glanced up from his gaming console to see what his girlfriend bought. "Too slow, Shoyo. I pre-ordered it a couple months ago, and I'm playing it right now." The clicking sounds of the buttons filled the air.

"Aw, man, I thought I could do it this time," Shoyo pouted. "It took me forever to find one."

He glanced at her from the corner of his eye. "But thank you."

Shoyo entered Kenma's room and plopped on the couch next to him. She peered at the screen of the console and was impressed that he was halfway done. The game was a hero's journey to rescue a princess and defeat the demon lord. However, the game developer decided to add a spin to it and install secret routes with different missions. A couple minutes passed as the air conditioner and the sounds of buttons filled the void. Shoyo sighed at the lack of attention when she decided to drop by.

"Kenmaaa, I'm bored. Let's do something." She poked Kenma on the cheek. "Please?"

Kenma didn't even look up. "Let me just finish this level."

"But that'll take forever!"

"I'll make it quick."

Shoyo crossed her arms and pouted.

Kenma's girlfriend knew how long he could be playing a game. Sometimes, it was twenty minutes; other times, it could be as long as four hours. It just depended on how fast he could finish to game. With this one, she knew it'll be the one that'll take awhile. Stupid game developer. Stupid secret missions, she thought.

She stood up and proceeded to inspect his room for the millionth time that she's been there. His desk was nice and tidy as usual with his school books stacked onto one side. Her footsteps were muffled from her socks as she walked around the room. His bed was made, and his windows were open just a crack to let the littlest bit of sunlight in. Shoyo decided to flip them open all the way to make in the room seem a bit lighter.

She heard a hiss in the background and laughed. "Come on, Kenma. You need a bit of sunlight in here. It's always so dark."

At his grumble, she resumed her inspection, peering at the gaming posters in his room, until she was met with a bookshelf. Seeing one of her favorite mangas, she picked it up and plopped back on the couch. Nestling her feet onto Kenma's lap, she started reading.

Kenma was concentrating so hard in his video game that he didn't notice Shoyo falling asleep until he heard a thunk. He looked to his right and smiled a bit at the sight before him.

Shoyo's short orange hair was cradling her face, albeit a bit messy with baby hairs sticking out everywhere. The light coming from the windows was dancing around her and made her face aglow. Her left arm was hanging from the couch, the manga being inches away from her hand. Her light snoring could be heard, and Kenma chuckled.

"Cute," he commented.

"Mmm," Shoyo hummed as she twisted to the side before falling asleep.

Suddenly, a wicked idea popped in his head. He was going to surprise his girlfriend with it later, but this seemed like a perfect opportunity to try it out.

His smile didn't look so cute anymore.

0o0o0

Something was definitely wrong.

Hinata Shoyo just knew it. She remembered going over to her boyfriend's house to surprise him with a gift that he already had. Then, she fell asleep as she was reading a manga of his. She was conscious, but her eyes were still closed. In the background, she could still hear the clicks from the video game he was playing.

But that wasn't it.

She was sweating and hot. So very hot. Her clothes felt like they were melting on her. It was as if it was already summer in Japan, but that wasn't right. The season was still spring and a bit chilly, so why did the room feel like she was bread being baked in an oven? She twisted side to side to try to get rid of that burning sensation, making her rub her thighs together as well.

That's when she felt it.

Her eyes snapped open, and she gasped. Kenma glanced down at her and smirked. He continued playing his video game.

"K-Kenma?" Shoyo moaned.

"Yes, Shoyo?"

"Why the hell," she moaned once more, "d-did you put a vibrator in me?"

"I have no idea what you're talking about."

Hinata Shoyo's eyes rolled back as she could feel herself building up for a release. She clutched the sides of the couch, and her breaths quickened. Suddenly, all she could hear was the rapid pace of the buttons Kenma was pushing. It sounded louder and got faster. Her eyes clamped shut. She imagined Kenma using those fingers to push inside of her. Deep and fast. She was so close. She didn't know how long she had been asleep for nor how long the vibrator in her vagina has been going on, but she was so close.

Then the vibrations suddenly stopped. When the vibrations stopped, the sounds of the buttons stopped as well.

"Shoyo?"

She opened her eyes and glared at Kenma, frustrated that she was kept from release.

He held up his console. The screen revealed that he had beaten the level, congratulatory words being displayed. "Cool, huh? I hooked up the vibrator to my console using Bluetooth, so whenever I start playing, it'll turn on and sync with the speed I'm hitting the buttons," he said, "almost as if I was the one doing that to you." He tilted his head and smiled.

Shoyo wasn't impressed. Well, she was, but she was still frustrated at being left hanging. Her jaw dropped at his mischievousness. She growled and tackled Kenma. "You bastard," she shouted as she tried to grab the controller from him. "Who said you could- Ah!"

She slumped forward on him and gripped his shoulders. At the last moment, when his girlfriend straddled him to try to take his game controller, he fiddled with the buttons, activating the contraption inside her.

Her mouth was breathing right into the nape of his neck, bristling his hair. Her fingers were tight on his shoulders, and he could feel her nails digging into his shirt. Her knees trapped his hips and were strangling his legs. Nevertheless, he enjoyed this position—a position where his energetic girlfriend was writhing on top of him while he played the newest installment of his favorite game.

She, on the other hand, was trembling.

The vibrator inside her was erratic. Sometimes it would go fast, and sometimes it would go to a slow hum. She hated it the most when it would just stop, though. The inconsistency of it all was fucking up her mind, teetering her on the edge of release but not.

"K-Kenm-ma-ah!" she moaned and buried her head in the crook of his shoulder, biting his neck to keep her from being too loud. Kenma grimaced at the pain. Her fingers dug into his back, and he could feel her thighs trembling. Her skirt pooled around their thighs, covering the essence she had spilled upon them both. When she came down from her orgasm, the devil didn't stop the attacks under her skirt. The hum of the contraption kept going, and she couldn't stop the whimpers escaping her lips.

However, Kenma wasn't faring too well either.

The way she clutched around him like a snake about to strangle a mouse made him pulse. Her hot breaths only increased his desire to be inside her while his little friend stood just a little taller. His arms were underneath her armpits, still continuing to play behind her back. He was about to beat this next level. If he loses, then he would have to start the level all over, and he didn't want that.

His volleyball team praised him for his concentration and control, and he plans on sticking to that reputation. Left. Right. Jump. He was thinking hard about his fighting combinations when he almost dropped his controller.

"Shit," he muttered.

He knew his girlfriend was going crazy about the stunt he pulled, but he didn't expect her to go this crazy. It was his fault really. He shouldn't have done it in the first place.

Shoyo was rubbing on him. No, not rubbing. She was grinding on him. Hard. His dick wasn't semi-soft anymore; it was trying to get out from its restraints. One of her hands had snaked their way into his shirt, feeling up his torso. His abs turned taut, and Kenma's grip on the console tightened. Surprising him even more, she slipped her hand underneath her skirt, and he could only guess what she was doing to herself.

Shoyo was going mad. Feeling his skin wasn't enough, so she had to turn to masturbation since it didn't seem like Kenma was going to break his concentration. Her fingers brushed against her pearl, and she moaned. She rubbed against her lips using her cum from her orgasm. Shoyo knew she was affecting her boyfriend with the way the vibrator would slow down. That meant he was losing his concentration. But that didn't help her. The vibrator wasn't enough nor was fingering herself.

She needed more.

"I- ah, don't like this game y-you're playing," she whispered in his ear. Her warm breath sent a tingle down his spine. The apex of her legs met with his dick, and he shook. "I-if you're n-not, ah, going to h-help me," she groaned, "I guess ah! I'll do it myself."

At that moment, she lifted herself up and pressed down hard on his rising friend.

"Fuck, Shoyo." He couldn't do it. Kenma dropped his video game, making a loud clack on his wooden floors. The vibrator stopped, and she slumped from the oversensitivity of her vagina.

His thumbs should have been numb by how hard he was pressing the buttons on his console due to his hard concentration, but they weren't. Even more so, he was surprised he resisted this long. His fingers curled around Shoyo's hips, skin meeting skin. He captured her lips with his, and it was a battle. She attacked using her frustrations from trying to get another release, and he attacked since he needed a release.

He nipped on her bottom lip and plunged his tongue into her mouth. Shoyo's hands were entangled into his blond and black hair, still grinding on him to create some sort of friction.

Slowly, Kenma's fingers slid from her hips to inside her panty, leaving a fiery trail. First, he removed the vibrator from inside her, which was easy to get out since she was so wet. Pulling it out and throwing off to the side, he slid two digits inside her walls.

Their fervent kissing stopped as she threw her head back. "Oh, god! Kenma!"

Waking up to a vibrator inside her and not knowing how long it has been there for made her overly sensitive, even more so as her boyfriend curled his fingers and hit her G-spot. He kept thrusting his fingers inside her and hitting that perfect place. She was drowning and swimming. His slow pace was keeping her off the edge, driving her to insanity.

But she didn't forget that stunt he pulled.

Using all her willpower and the strength of her legs (it was a lot of willpower), she was able to flip them over. She was thankful for the strength in her legs from jumping everywhere as a decoy on the Karasuno team and maybe even contemplated to personally thank Kageyama for his demanding sets.

Now, she wasn't straddling Kenma's lap. Quickly, she had grabbed his hand from under her skirt and flipped him to the side. Dazed, he looked up at her from his laying position on the couch, his legs hanging off the arms of the furniture. She had a triumphant smile on her face, arms crossed.

"This is more like it."

Still aching, she pulled down Kenma's sweatpants, which were stained from her earlier orgasm, and released his member. For a man that wasn't the tallest compared to his volleyball team, his dick had more girth than length to it. Kenma's brows furrowed at the change of positions, nose wrinkling in dismay. This isn't how it's supposed to be.

His eyes grew wide when he felt her grab his length. Shoyo had him in her hand, stroking up and down. Her touch had him gripping her legs, fueling the desire to be inside her. She stroked up and down, brushing past his balls.

"Shoyo," Kenma growled at her teasing grip.

She looked down innocently. "Yes, Kenma?" She fluttered her lashes.

"Stop teasing me."

"Whatever do you mean?" she replied, mimicking Kenma's response from earlier.

Two can play at this game.

While she basked in her domineering position, he had had enough. He hooked his fingers around the bands of her panties and ripped them, scattering the fallen debris onto his wooden floor. Her nostrils flared.

"Those were my favorite- Ah!"

After ripping apart the piece of clothing, he grabbed a hold of her hips and slammed her on his awaiting member. She convulsed around him and clenched her walls tighter, relishing in the girth of Kenma's dick. Her warmth and slick passage begged Kenma to pound into her, but he waited for a few seconds until she adjusted.

One would think the vibrator stretched her just a bit but no, Kenma gritted in thought.

Slowly, once he felt her wriggling, he picked her up just to slam her down back again. He thrusted into her like a starved animal. If she thinks she can be on top and try to control me, she has another thing coming.

Kenma's pace didn't slow as Shoyo was gasping and moaning. The pace was too much for her, and she could feel herself getting close. While she was bobbing up and down his dick, her breasts bounced. Kenma's eyes followed the path of her chest, mesmerized.

Shoyo needed more stimulation. Moving her hands from clutching the couch, she started kneading her breasts. She twisted and pinched her nipples. Her tank bunched up above her chest, and he was hypnotized at the show she was presenting.

"A-ah!" She was so, so close. One last thrust sent her over the edge, and she fell into pieces. Her arm moved back to holding onto the back of the couch, trying not to collapse on him. Meanwhile, Kenma kept going, trying to find his release.

If he had to restart a level on his game, he had better get his orgasm, too.

After a few more thrusts, he grunted and spilled his seed inside her. Opening his eyes, he was blessed with the sight of his girlfriend.

In the midst of having sex, she had discarded her cardigan, so she was left in a tank and her plaid skirt. Once the again, the light from the window lit up her features. Her face was flushed as if cherry blossoms bloomed in her cheeks. Her lips were still gasping for air, and her hair was mussed into an orange halo. He wondered how lucky he was to have someone as bright as her to be by his side. When she first came up to him, he thought she was the sun. Bright and brimming with energy. He didn't know he started falling for her until Kuroo pointed it out one night.

Kuroo knew there was something up with his best friend. Although Kenma was always seen on his phone or some sort of gaming device, he was on his phone a lot more than usual. It wasn't until Kuroo had the balls to invade his best friend's privacy when he was in the bathroom that he found out. That night, Kuroo had read the texts between Kenma and Shoyo.

That night, Kuroo asked Shoyo on a date acting as Kenma.

Kenma was annoyed to say the least, but in the end, it did score him a girlfriend.

Staring at her as she opened her eyes, she smiled. Her head was laying on her arm as she leaned on the backside of the couch. Collapsing down from her position and onto Kenma's chest, she sighed and gazed into her boyfriend's eyes.

He could feel her abused nipples poking through his shirt and their essence still leaking between them. His hair stuck to his neck from the sweat, and he closed his eyes. He was mentally and physically tired.

"Tired already, Kenma?" she asked, squeezing her walls around the member that was still inside her.

Okay, he was tired but not exhausted yet.

She squeezed him again, and his thought process stopped altogether.

"You know how my stamina is, Shoyo," he replied, clenching his jaw.

"Hmm," she hummed as she slid her hands underneath Kenma's white shirt. "But when you were playing against us in the Spring Tournament, your stamina seemed reeeally good." Her nails scraped along his sides, and he cursed when she pinched his nipples. His penis didn't feel so flaccid anymore.

"Think of this," she kissed him, licking his lips, "as leveling up your stamina." She crawled up towards his ear and bit his lobe as she gave a hard grind.

That had been his undoing.

Sitting up straight, Shoyo fell backwards.

"Kenma?"

He was still inside her, and he was sure she must've felt the pulse from his throbbing member. Picking her up by her thighs, she encircled her legs around his waist to keep her from falling.

"What're you-"

Suddenly, he threw her on his bed. Stripping off his sweats and shirt, he crawled towards her like a lion stalking its prey. Kenma's eyes dilated, and Shoyo knew she was in trouble. When Kenma's eyes get like that and isn't talking, he's in a mode where he's analyzing everything. Every possibility and impossibility, every outcome. Usually, he would direct that kind of concentration in a game he was playing or in volleyball, but this time, it was directed at her.

Sure, they've had sex multiple times, but he never looked at her like this. This time, she was the thing he was concentrating hard on, and she didn't know how to feel about that. All she knew was that he's dangerous when he's in that zone.

"Let's level up, then," he muttered.

He didn't bother to take off her clothes. He attacked her nipples, sucking and twisting the other. Shoyo gripped his hair and tried to rubbed her legs to get some sort of friction. Unfortunately, Kenma's knees prevented her from doing just that.

"Oh! Kenma!"

With his free hand, he inserted two digits in her hole once more. Her head pushed against the mattress in ecstasy.

"Don't stop!"

At her command, he kept thrusting his fingers into her, repeatedly hitting her G-spot. After he deemed it enough that he had marked her breasts raw, he nipped along her neck until he reached her lips.

Her cries were muffled as his tongue explored her cavern as if it was a pirate seeking a cove for treasure. Kenma removed his fingers from her vagina and slammed his penis into her, his mouth absorbing up all her gasps. Filling her up to the hilt, he started to move. Shoyo hooked her legs around him, and she clutched his small shoulders. He may look small in stature, but being able to be up close and personal made her realize how much muscle he was hiding in plain sight.

Changing to a new postion, he lifted one of her legs to his shoulder. Shoyo cried out in ecstasy. He was hitting deeper than ever before, and she clutched his bed sheets. She felt like she was floating, and she needed something to hold on to to keep her grounded.

"Look at me," Kenma said.

She didn't know she had her eyes closed until Kenma had said that. Opening her eyes, she locked her gaze with his cat-like pupils. Her back arched.

"K-Kenma, I'm close!"

He took that as a signal to increase his pace. Their bodies were slick with sweat, separated by only a few articles of clothing. His deep and fast thrusts continued even after Shoyo shouted out his name. Once more, he moaned at the pleasure of being able to ejaculate inside of her, dismissing the idea that they had used condoms once upon a time.

Tired, Kenma collapsed on top of his girlfriend, closing his eyes. They laid together in silence, enjoying the company of each other and catching their breath. His head was in the crook of her neck and sighed in contentment.

Shoyo laughed and poked him in the head. "Where did you get that vibrator? I didn't take you the type to buy something like that."

"Kuroo," he grumbled.

"Ah, makes sense."

"He found it in some store and thought I should use it."

Kenma had received it a week ago from his best friend. He left it on top of his bed, wrapped in Christmas paper even though the holiday had passed. Cheapskate.

But he did have to thank him later for the new toy.
