Work Text:

When it comes to FPS games, nobody could match Shiro’s aim and accuracy. She calculated each shot and made it seem like her bullets were tracking the enemies, to the point that their fast reflexes wouldn’t be able to dodge them. She’s always on the offensive, rarely ever on defense. You’d think you were playing against a computer or a cheater.

When she plays, she gets into that hyperfocus mode that even the deafening sound of an explosion wouldn’t make her flinch. Although, the husky sound of her brother’s whispers, his lips brushing her ear, or his cock stretching her from the inside, might just make her falter a little…

“Watch out, Shiro-san. Our HP is getting low. Why don’t we find some healing item, yeah?” The rasp in Sora’s voice sent shivers down her spine, causing her to press her thighs closer together.

Shiro ground her teeth at the use of honorific. He only calls her that when he’s asking her for a favor, showering her with praises, or, like her current predicament, when he’s purposely trying to get under her skin. He sure knew how to rile someone up.

And what was more infuriating for her was the fact that he used words like ‘our’ and ‘we’. She so badly wanted to bark, “I’m the only one doing all the work here!”

How did she get into this situation again? Oh, yeah. It started with “I’m bored,” which led all the way to “Why don’t you play that new game we bought while I shove my cock inside you only to not fuck you the entire time? If you win, I’ll give you some good dicking as a prize!!!

Well, that’s not exactly what he said but that’s the gist of it.

It sounded so fun and easy. That’s why she’d agreed to it in the first place. Had she known that her brother was going to be so troublesome…

For the last half an hour or so, Sora had made her sit on his lap, slipped his cock inside her, and made her play using Blank's main account. He’d pepper her skin with hungry kisses, from her jaw to her shoulder, making her head spin and distracting her. It was challenging enough playing solo without his support, so having his hands and mouth all over her body only made it harder for her to keep her head in the game. Even the godliest gamer has their weaknesses too, you know?

Nii… Stop it.” Shiro told him. She moved her head away avoiding him, but his lips still chased after her neck. He gave her a small bite there before licking over the same spot. 

“Whyyy? I thought you liked my kisses?”

She ignored his whining, trying to focus on the game. But, just when she had an opportunity to take down an enemy, Sora slipped one hand under her top and pinched her nipple, making her jump and miss her shot. “Bad timing…!”

A low chuckle escaped his mouth as if it was so entertaining to him. Oh, how his voice annoyed her. It made her pussy throb with want. Internally, she wished that her brother would just start fucking into her. Before she realized that she'd unconsciously started grinding on his cock, he hurriedly put a hand on her hip to stop her movement. 

“C'mon, Shiro, you're a good girl, aren't you?” He inhaled a sharp breath through gritted teeth. She could tell he wanted it too. But, still, her dear brother told her, “No cheating, okay? You'll get your reward when you win.”

She couldn't wait any longer. Frustrated tears pooled in her eyes, blurring her vision of the screens in front of her. Screw this stupid game. She decided to cast her ego aside and begged. “Please, I can't… do this!”

His lips brushed her neck and she could feel him grinning. His voice husky, Sora whispered, “Shiro-san. ‘Blank will never lose’, remember? So, do your best, little sister ♡”

Shiro had had enough. Without thinking, she spat, “Nii… You're the worst!”

Once again, he only chuckled. Sora grabbed her hips tightly with both of his hands. “I think what you meant to say is–” He lifted her by the hips and quickly slammed her back down his cock repeatedly, “Nii, fuck me already!

He faked a high-pitched voice, mocking her. She had half a mind to come up with a snarky remark, but she could only let out a lewd cry as he kept using her like an onahole.

Fuck my tight little loli cunny, Nii! That's what you wanted to say, right, imouto?”

Then, he stopped. She didn't get to orgasm yet but her pussy was twitching like crazy. Couldn't he at least let her cum once?! How cruel… Her brother could be such a sadist sometimes. 

All the while, in the game, she took a hit from an enemy. She decided to retreat and quickly went to find some healing items instead just to be safe. There'd be no way she could fight them head-on while her mind was still all jumbled up because of that.

Panting, she repeated her insult but laced it with venom this time. “You're… the worst!!!”

With no trace of hurt in his voice, Sora replied, “Oh, how you wound me, baby.” He then placed a quick peck on her jaw and promised, “Just finish the game and your brother will give you what you want, ‘kay?”

Quitting wasn't a choice. Obviously, she couldn't ruin Blank's reputation just because her brother wouldn't let her cum. Accepting the fact that there was no shortcut out of this ‘game’ other than to finish it, Shiro decided that she was going to end it as fast as she could. She'd push through Sora’s endless teasing and take down all of her opponents to achieve victory. Yes, even if her brother wouldn't stop kissing the skin of her neck and fondling her undeveloped breasts the whole time…

“Another victory added to Blank’s zero-loss record! Now, you get your prize!” Sora cheered. When he lifted Shiro off his lap to bend her over the desk, his voice suddenly dropped an octave. “Took you long enough, Shiro. Your brother only has so much patience, you know?” She could hear the burning lust and need behind his words.

It took longer than she liked, but she had finally finished the game. It was now time for her to reap the fruit of her hard work, but it seemed like Sora was more eager to give it to her. As soon as Shiro was bent over, he flipped her skirt up and shoved his cock back into her, jamming it in as far as it could go. He didn't waste any second waiting for her to give him the green light; he didn't need to. She'd been begging for this. He started thrusting into her and the squelching sound of her soaked pussy filled the room along with their moans.

“Is this it? Is this what you want, little sister?”

He was fucking so deep into her that Shiro thought she could feel him in her throat. She couldn't form any coherent thoughts, much less words. She could only cry, “Nii! Nii…!”

“You're so damn wet, Shiro. Do you want your big brother to fuck you that bad…? Hah. You're such a little pervert, you know?”

The desk shook with every thrust, shaking the monitor screens sitting on it along with them. Shiro couldn't be bothered to tell him to slow down because she needed this. She almost went crazy waiting for this. So, instead, she decided that she was going to savor her sweet reward minus the risk of breaking their PC.

Nii! Bed! Bed…!”

Without any argument, Sora carried her into their futon. Shiro immediately got on her hands and knees, pushing her bottom up as if offering herself to him. He gave her butt a light slap and a compliment, “Cute.” He wasted no time aligning his length to her entrance and pushing it in, pulling a groan out of her.

Shiro’s hand became tangled with the sheet. Her fingers grasped it tightly, pulling it taut. Maybe it's only because she was so small, but it felt like Sora was stretching her open. And he's fucking her so right; hitting her best spots. Nobody knew her body like her own big brother. 

“Feels good?” Sora asked, his big hand squeezing her little butt.

Shiro nodded and looked back at him. “Mhm. So good, Nii.”

He let out a chuckle and she could imagine his smug face. Shiro didn't mind stroking her brother's ego as long as she could get something out of it. As she expected, he asked, “Want me to go harder?”

“Yes!” Her answer was fueled with enthusiasm.

Sora held her hips tightly and began pounding into her. He was hitting spots so deep inside her that it hurt, but Shiro couldn't stop herself from arching her back and moaning.

“Ahh. You're so fucking tight,” Sora groaned. “I'm about to cum, Shiro.”

“Do it inside…!”

“Fuck, you're kinky.” A raspy laugh escaped his lips. “Then, beg for it, little sister.”

Embarrassment brought heat to her cheeks. Shiro only whined, but her brother convinced her.

“C'mon. I'll fill you up real good,” he promised, panting as he kept pistoning in and out of her. “Say ‘please’ and I’ll give you anything.”

Quietly, she murmured, “Please, Nii...”

“‘Please’ what? Use your words.” 

“Please, do it inside…!” Shiro could feel herself getting close; her pussy tensing and flexing around him. “Cum inside me, Nii!

With those words, Sora moaned her name and spurted into her, filling up her little belly with his warm seed as promised. His movements faltered, but he wouldn't stop until his sister finished. He brought his hand to her crotch, massaging circles onto her clit.

Nii! I'm gonna–”

Before she knew it, her orgasm hit her entire body. She curled her toes as she gushed out, drenching the futon. Her legs trembled so hard that she couldn't hold herself up anymore. When they finally gave up, her small figure fell flat on the bed.

“Shit! Fuck. Shiro, you okay?”

She was panting, her body still shaking. Sora flipped her over and held her close in his embrace. They rested like that for a while, Shiro laying on top of her brother as he held and comforted her until she fully came down from her high.

“It's okay. I got you.”

It took a moment, but Shiro regained the energy to speak again. Not sure what had happened, she innocently asked, “Nii, I… peed?”

Sora couldn’t hold himself back from laughing, “Don't worry about it. Felt good, right?”

She silently nodded. It did feel good. But, she also felt a hint of guilt thinking of how her brother would have to take care of the mess she created.

Neither of them made a mention of it, though. Sora merely patted her back and said, “Let's clean up.”

“‘m tired.”

“C'mon, just a quick rinse. I'll wash you up, then we can play whatever you want after that, ‘kay?”

That got Shiro to reconsider. Looking back at how their gaming session earlier was pretty much torturous for her, picking a chill and casual game to play with her brother for the rest of the day sounded quite nice.

“Okay,” she finally sat up, still on top of him. “Nii.”

“Hm?”

“I love you.”

“I love you too, baby,” he intertwined their fingers together. “More than anything.”

And that was another day of fun and games for the gamer siblings, Blank~
