Reward-and-punishment (2)**

Chapter 51: Reward-and-punishment (2)**

—

["Hello, and nice to meet you, I am Principal Nezu."]

Looking at the hologram floating above the letter placed on the table, Neji couldn't help but feel pleased.

["As you've learned from reading the letter already, you have not only passed the exam, but you've also got 1st place in it. This is certainly a big achievement, so you should feel proud. You have shown great strength that'd help the Hero Society grow in the future and…"]

The hologram started to give a long ass speech that bored Neji to death, but he nonetheless listened to it all the way. Acing a competition, game, or exam never failed to make him feel delighted. So he didn't skip the flowery words he was getting, even if they were boring and useless, because they were also a part of his achievement.

Next day

"Wake up~"

[Super Idol de xiao~]

"Mhmm…"

I slowly opened my eyes feeling the tug in my shirt. Light music was playing in the background. Who is it so early? As my blurry vision corrected itself, I blinked.

...What?

"You're up!"

A frown crept on my face as I looked at my older sister, Nejire, who was on top of me with my shirt in her hand that she seemingly took off just now.

"Nejire…?"

She tapped to my forehead with her fingers.

"It’s ‘Nejire-nee’, you brat."

"Okay, sure.” I rolled my eyes. “But why am I chest naked?"

She pouted at this. "Because you weren't waking up!"

I was busy playing with my quirk last night. I learned something new… anyway, that's not the point.

"It still doesn't make sense. Why am I chest naked? And… why are you wearing this?"

As light music was playing on the side, with Nejire pouting, I looked down at her body. She was wearing an oversized T-shirt. My T-shirt. It was made by Mom for me, or for the future me since it's oversized. 

"Why you wearing my T-shirt?"

Her pout disappeared as she giggled. "I heard men like when their partners wear their clothes."

She's not wrong. But that’s exactly the problem. Teasing me like this in the morning….

Just then, Nejire lowered her gaze to my abdomen, her lips slowly curling up.

"Ahh, I can feel heat reaching my stomach from that thing…."

I smirked. Well, that's a lot of development. She doesn't stutter before teasing anymore. It seems her months of researching is helping her… don't ask why I know this.

I put my arms around her waist and pulled her to my chest, her butt falling on my abdomen.

"Then may I know why My Queen has summoned me so early?"

She pouted and wrapped her hands around my neck. "I am hungry."

I deadpanned. What? Does she think she's really some Queen? I wanted to say, 'Why wake me up so early just because you're hungry?', but I stopped as I realised something. 

Ah fuck, she's doing wordplay.

To think I have fallen so low that it took me 5 seconds to realise it… tch, shame on me.

I smiled at her and laid on my back leisurely. 

"Hungry? Don't you see this?" I pointed at myself. "For your information, I am a milk factory."

Nejire blinked, a little dazed, but soon a smug smile appeared on her face. 

"Oh my, what a stroke of luck. I was in fact looking for milk..."

After looking at my lips for a while, while I spread them into a smile, laughing at the Chinese song playing in the background, Nejire leaned at me suddenly and locked her lips with mine. Her left hand pressed down on my shoulder while her right hand left for my crotch. Her breasts pressed my chest down while her blue eyes locked with mine.

She likes pushing me down, a lot, apparently. I expected this from when we were kids. She used to climb on top of me every now and then, after all. I can of course turn this around and play with her with just my hands alone, but this is fine. She can enjoy her dom moments. I don't want to scare her needlessly.

"Mhmm…."

She moaned as my tongue wrapped around hers like a snake. But she pressed down harder instead of giving up, her body was getting hotter as her tongue was getting harder to hold off. She was about to slip off, but I bit her tongue causing her to moan in my mouth. 

Soon, as I felt her breathing slowing down, I decided to release her, just as Nejire separated her mouth with a plop sound.

"Hahh…"

She sat straight on top of me and looked at me from above all while I put my hands on her curvy waist.

"I'd suggest you stop here," I said. "Or things might get hot."

"The AC is on." She replied with a smirk. "This much heat is nothing."

Oh my.

I chuckled, eyeing her lips. "Mom and Dad aren’t home?"

"No~" She yawned with a stretch of her arms. "They're on a business trip again."

My parents go on business trips a lot, it increased after I came back home from my Japan trip. Nejire didn't like it before, but she is in fact looking forward to these trips after we got closer.

Anyway, I should probably stop here. We went as far as eating each other out once, but we are still yet to do penetration yet. I could of course have done it anytime, but I didn't want to push her too far like I did with Kimi, and instead concluded to let her decide on it.  

Suddenly...

"Let's do it today."

….Nejire looked at me with a blush, causing me to still briefly before blinking.

Huh?

She leaned to my ear and whispered, "Well, the Christmas gift didn't work out so well…" Nejire mumbled in his ears. "So I want to make up for it by gifting you this body for acing your entrance exam."

Huh… oh shit. It's happening.

While I laughed like a maniac inside my head, Nejire grabbed my right hand and put it above her chest, her gaze avoiding eye contact. 

"Go on… c-continue."

I opened my mouth to say something before smirking softly.

"But of course."

—

Nejire wasn’t sure about this at first. She wanted their first time to be special, so she wanted to do it on his birthday, or at least on her birthday. But this is 4th March, and both their Birthdays are in October and November respectively, she couldn’t wait that long... she was also scared that Neji might get disappointed at her for not letting him cross the line. After all, she read many articles where one partner left the other because of non-active sex life.

So she thought the entrance exam was a good enough opportunity for them to become one, and so they were doing exactly that.

“Hahh…”

Nejire panted while her younger brother's hand ran through her back, her ass, and her waist. She could feel that magical touch of his that Kimi talked about before. 

‘...One of his magical items?’

He never used this on her before for whatever reason, and she was regretting not initiating things before. To think she missed such a thing…. 

A moan escaped her lips just as she was thinking this.

“N, Neji…”

Her voice quivered while her younger brother sucked on her nipples like a child sucking on his mother. She retained a smile on her face seeing this, she almost felt he was a child if not for his boner poking behind her.

Nejire had her T-shirt pulled up, revealing her boobs and bare legs. She wasn’t wearing any panties, so Neji’s boner under his pants was poking directly under her private region. 

“Mhm~ N-neji, slow down~”

She gasped for air as Neji instead bit her nipples with his teeth. His teeth rolled her nipples while his tongue licked around. Both their bodies were touching, she could feel his sweat sticking to her skin even under the AC.

Neji laughed inside his mouth seeing her reaction, which caused her to pout, but as Neji’s hand squeezed on her ass sharply, her eyes jumped up and she groaned.

“W-what’s wrong with your hands?!”

She couldn’t understand it at all, why was she feeling this chilling yet warm feeling rushing through her spine at each of his touches? 

Neji laughed a bit more before he rolled around and pushed her down on the bed with him being on top. 

“Last chance, are you sure?” 

He asked, smiling, knowing the answer already.

Nejire didn’t give a proper answer and gave an ‘Mhm’. Neji stared at her expression briefly before snapping his fingers which teleported his clothes inside his inventory. 

Nejire mumbled a wow as his well-defined boy came into her view. A gamer’s body is supernatural, that’s true even for Neji’s System, being made of stats, it’s no wonder his body would look perfect from all sides. 

Nejire bit her finger as her eyes slowly trailed down his face, chest, abs, and finally landed on his shaft. 

She gulped softly as a trail of sweat fell from her forehead. Would she be fine with that inside her?

Probably… not. But it’s too late to back off now.

Being naked between her legs, Neji's shaft sprung up and landed on top of her lower abdomen. 

“It’s hot…”

“It is?”

Neji acted oblivious to which Nejire pouted again. But as Nejire slowly rubbed his dick with her lower lips, she gasped softly.

“S, stop this already!”

Nejire cried.

"How about no-"

She pouted at his rejection and to spot him, she instead instantly pushed her hips forward, causing Neji’s dick to enter her in an instant, at the same time a loud groan left her mouth.

“AhHN~!!”

Pain?! It hurt! 

She immediately realised it was a wrong move from her.

Neji stopped briefly at this. She has always been the curious type, but this was still his first time seeing a girl taking his dick inside her by herself in a single shove. 

Nejire’s eyes almost rolled up just as blood trickled down from inside her pussy. Neji smiled softly and used Touch of Nirvana in his shaft, causing the pain to turn into pleasure just as her groan turned into a moan.

The long, hard, and warm thing inside her was thumping like a heart, another person was inside her, no, her own brother was inside her.

Countless memories of her childhood with her younger brother flashed by her eyes. She has been with him since when he was but an infant, yet look at this now. 

"Oh my god, oh my god!" Nejire clenched the bed sheet while calling for God. It was probably a bad idea to have shoved the thick cock inside her tight cunt. Now she was regretting, this time not because it hurt, but because it was too pleasurable!

Neji breathed above her while both his palms were on either side of her head. He waited for minutes before Nejire finally nodded.

"Hug… Hug me."

He did as she asked. He leaned over and brought her close to his chest just as Nejire wrapped her arms around him. 

"You can... continue- Mhm!"

Neji's hips simply moved inside her just as Nejire let out a moan. She wasn't sure how good she was feeling, it didn't even feel real.

Pa!

Soon, the sound of flesh meeting with each other sounded out around the room as it also got filled with the sound of Neji's grunts and Nejire's moans.

'Oh my-', 'Good Heavens!', 'Harder!', these types of moans were filling the sound-proof room, the sound was then vibrated back and slapping Nejire's eardrums, causing her to blush at her own lewd voice. 

Sex is beautiful.

She couldn't help but huff. She has always been the curious type, and this time her cautiously only increased. She wondered how it'd feel like if she was at the top, she wondered how'd feel like if Kimi was watching her getting railed, she wondered how she'd feel seeing Neji fucking Kimi passionately while she sat on a corner of the room. Many things flashed by her brain, as her inner heat slowly took over her. 

Her voice started to rise as her words started to get more vulgar. 

"Goddammit! You bastard!"

She found pleasure in cursing. It was exciting. Calling her partner in bad names was making her feel better. She wondered how it'd feel being on the receiving end? She should ask him to try on her later.

"Fuck me!"

As his hips moved at the speed of thunder, Nejire couldn't help but move her body accordingly. She matched his rhythm as each of his thrusts reached deep inside her, hitting her womb each time, which should be painful but wasn't because of whatever magic he was using.

Pa!

"Break me!"

"Ahnn!"

Multiple different kinds of moans left her sweet voice that only made Neji's rock hard cock to become harder. It was almost as if he had a certain Hardening Quirk. 

"You big dicked cunt!"

Pa!

She cursed at him to which he instinctively spanked her soft, plump, ass. She again found pleasure in this too. Getting hit was pleasurable as well. She was almost starting to believe that anything in sex feels good.

"C-choke me!!"

She hesitated before yelling it out, to which Neji blinked, but he nonetheless didn't stop thrusting before he chuckled softly and pushed his hand against her neck, causing her to cough on. He almost pulled his hand back seeing her rolled eyes, but as a creepy masochistic smile appeared on her face, he stopped and continued choking her.

Her gagging moans filled the room further just as Neji got lost in thought.

Is his sister a masochist? He soon realised that's not the case. She's a 'switch'. She can be whatever she wants depending on the mood. And she was currently in the mood of being dominated. 

'Switches are fun.'

He couldn't deny it. Nejire was fun by herself, but it was really a switch, her fun just got doubled. 

"Aug!"

Her gagging moans were all fun and games until she rolled on the bed and pushed him below under her, her ahegao face slowly returning to normal as she smiled seductively.

"Now…" she panted as she sat on his dick. "Pleasure me."

It was almost horrifying to Neji how her personality changed within the last 5 minutes, but he could only chuckle at it.

"As you wish, my czarina."

And just like that, a horrifyingly hot morning passed for Neji and Nejire. If not for Kimi calling them for food with a tomato like face, they'd have been into it for the whole day, and maybe even night. After all, Nejire had the stamina to stay on the line with Neji's monstrous stamina.
