Chapter 1

Kushina hummed a catchy tune in her head as she was currently making breakfast. There was a reason as to why she was so happy now. She and her son tasted the forbidden fruit last night, and it was the most amazing thing she had ever done. Second to giving birth to Naruto.

Said blonde was now waking up after the long night of passion he had with his mother.

He yawned as he walked out of the room and spotted Kushina making breakfast. She was also still naked and didn't seem to notice him.

He couldn't help but grin at how beautiful she looked like without any clothes. Getting an idea, he tiptoed over to her and made her jump by reaching up to her and grabbing her breasts.

"Eeeek! N-narutoohhh~" She moaned as she felt his son grab her DD-cup breasts.

Naruto grinned and began to lightly nip her neck. "Don't you think it would be bad if someone peeked in here and saw you naked? Or is that what you're hoping for?"

"I-I..." She tried to answer with a blush.

Naruto pulled back as he knew his mom would be mad if breakfast was burnt because of him.

Kushina pouted, but understood that breakfast had to come first.

Soon the food was ready and the two enjoyed a breakfast of eggs and bacon completely in the buff.

"This is delicious Kaa-chan!" Naruto said happily, making her blush.

"Thank you Naru-kun." smiled Kushina. They went on to clean their plates of the food before they heard the doorbell ring.

"Who could be here at this hour?" Asked Naruto in surprise.

Kushina shrugged before Naruto ran to the room to get his clothes before making his way to the door.

"Alright, who is it?" He asked as he opened the door, and was surprised with who was there.

It was a tall girl with blonde hair like his that was fashioned in two pigtails. She wore a blue sweatshirt over a white tank top with a pair of blue jeans and black high heels.

"Naruko-nee?" Naruto asked in surprise upon seeing his older sister.

"Hey there Otouto." smiled Naruko pulling her little brother into a hug.

Naruto blushed upon noticing his sister's D-cup breasts and her developed body.

"Where's Kaa-chan at?" asked Naruko pulling back as she walked in.

"In the bath changing..." Naruto said before he noticed a younger girl with red hair. "Minna-chan?"

Minna had glossy red hair with a ponytail on the right side of her hair and had a green sweater on with black shorts and blue sandals.

"Onii-chan~!" She answered by hugging him.

"Hey Minna. You and Naruko just get here?"

"Yeah!" She answered. "Summer camp was really fun!"

These two girls were Kushina's daughters. Naruko was her first child who had gone to college a week ago while Minna had gone off to summer camp.

"So anything interesting happened at college, nee-chan?" Naruto asked his older sister.

"I tried to focus on my studies, but the guys there were big perverts." replied Naruko laying on the couch with Minna joining her.

"I see...did they try anything?" Growled the blonde in his overprotective sibling mode.

"A few times, but a swift kick between their legs got the message across." smiled Naruko.

Naruto chuckled at that because his sister was a black belt.

That was when Kushina came out of the bathroom with her hair still wet and her body wrapped up in a single towel.

Everyone fell silent as they looked at her.

"Kaa-san!" smiled Minna running up and hugging her mother around the legs due to her size.

"Minna-chan! Naruko-chan! How glad I am to see you!" Kushina said.

"Hey Kaa-san. Still going around half-naked I see ." grinned Naruko.

"Damn straight! I have nothing to be ashamed of!" Kushina boldly answered.

Minna looked confused by what they were talking about as Kushina headed to her room to get dressed. A little disappointed Naruto couldn't make a move with her daughters now home.

Said blonde was asking questions to his siblings about their studies.

"So, what classes did you take?" asked Naruto.

"Art, math, physical, and martial arts." Naruko answered.

"Did you manage to keep yourself from injuring the teacher?" asked Naruto as his sister had a tendency of sending each of her sensei's to the hospital.

"Well...at least Gai-sensei resisted long enough..." She answered sheepishly.

Naruto shivered at remembering the man and was thankful he wasn't his student. That jumpsuit was evil!

'But at least the weights are cool...' The blonde admitted to himself.

"So, did my little otouto find a girlfriend~!" smiled Naruko.

"N-no!" Naruto answered with a blush.

That's when Kushina walked back in with her clothes back on.

"Sorry for being late." Kushina said, taking a seat next to Naruto.

"Well, I'm gonna go take a nap in my room." stretched Naruko standing up and tickled Naruto's ear as she passed him.

Naruto just sighed as he payed attention to Minna, who was telling him about her summer camp experience.

"And then we all went swimming! But one of the boys had to go to the nurse because he was swimming in water with leeches." giggled Minna.

"Poor sap." Naruto said as Kushina agreed.

"Then we had cake that night!" jumped Minna in happiness.

Kushina smiled as she hugged her daughter in happiness, making Naruto smile.

Kushina held Minna there while Naruto walked to his room to change into some cleaner clothes.

Then after changing into a white sleeveless t-shirt and black shorts, he decided to go to Naruko's room to talk with her some more.

He saw the door to her room was slightly open. He pushed the door open to see if Naruko was still sleeping. Said blonde was sleeping on her bed...but naked!

Naruto blushed as Naruko's chest bounced with each breath as she was drooling a little and seemed to be mumbling something.

'Damn! She's hot!' He thought, subconsciously closing the door quietly and advancing towards her.

He got close enough to where he could reach out and grab her breasts if he wanted.

One part of him tried to stop him, yet another bigger part said that if he made out with his mother, what was stopping him from doing it with his sister.

He was inches from grabbing her right breasts whens he suddenly pulled him right on top of her as she was still sleeping.

Naruto couldn't help but blush as he found himself in quite the predicament.

"Mmm...no bartender...I can handle my liquor...why? Want me to kick your ass?" mumbled Naruko in her sleep.

Naruto sweatdropped at that as he tried to get out of his sister's hold.

She just held him there as his face was mushed between her breasts as she smiled in her sleep.

'Oh shit! How can I get out?!' Thought the blonde male in panic.

"Ooh, otouto...walking in while I'm in the bath...all you had to do was ask..." mumbled Naruko with a blush and smile on her face as she squeezed Naruto even tighter.

Naruto froze up upon hearing that before blushing,

'What? Is she into me?' he wondered.

He wondered why she could have feelings for him of all people...

But then he recalled that she and him use to always hang out when they were kids. Not only that, but she got closer to him after the death of their father...

Sometimes he would find her crying by herself and he had to hug her to get her to calm down.

There was also the incident where he was being bullied by a older kid, yet it was Naruko that put an end to it by knocking down the bully. After that she took on martial arts and made her as strong as she was now.

So one could say they always had a special relationship, just not like the one he and his mother had.

But now it seemed like Naruko wanted to be more than siblings with her brother. Especially if her dreams were anything to go on.

'Now what should I do?' Wondered Naruto. He got his answer as Naruko began to slowly wake up.

'Shit!' Naruto thought in panic at what his sister could do to him if she saw him in that position.

"Hmm, Naruto? Is that you?" asked Naruko sitting up.

Naruto froze up and could only look at her with fear.

"Did you come here to grope your sister? If so, you need to work on being more discreet." yawned Naruko.

"N-no! I just came to see how you were doing!" Naruto said in panic.

"What, you didn't even stare at my breasts?" pouted Naruko pressing them together.

Naruto blushed as he answered subconsciously "I did..."

"Well, what did you think?" asked Naruko with a waiting look.

"They're big." He answered.

Naruko smiled before hugging Naruto into her cleavage again.

"Then why don't we skip talk and go to the main event already~?" She suggested.

Naruto blushed as Naruko reached down and grabbed the noticeable bulge in his pants.

"A-are you sure about this?" Naruto asked.

"You're getting hard looking at your sister's body, and you're asking me if I'm sure about this? Kinda silly to say isn't it?" smiled Naruko kissing his forehead.

Naruto just nodded embarrassed before he kissed her on the mouth.

Both of them held the kiss as Naruko cupped her brother's cheeks.

Eventually after a few minutes of making out, they had to separate from lack of air.

"Now, let's let this fella out." grinned Naruko unzipping his pants. Then she gasped as soon as she saw how impressive her brother's size was like.

"Wow, you're definitely hung like a horse." smiled Naruko grabbing the large member.

"Not that much...just e-enough!" Naruto moaned as his sister began to give him a handjob.

"Looks good." mumbled Naruko lowering her head and kissing the tip of his dick.

Naruto just moaned as Naruko proceeded to give him a blowjob while teasing his balls.

Naruko tasted the salty taste of the cock and swirled her tongue around the sides and tip while gently rubbing the balls with extreme care.

"Damn! W-where did you learn that?!" Naruto gasped.

"Lots of porn." smiled Naruko sucking on one of the balls.

"With Kaa-chan around?!" asked Naruto with a big blush.

"I kept my door lock." she spoke sucking on the tip.

"Right..." Deadpanned the blonde.

Naruko began to bob her head up and down while sucking much faster and began to squeeze his balls a little rough.

"Damn...I feel like..." But just when he was about to cum, Naruko put her hand in a firm lock on his penis!

"Not so fast. I need to make sure my breasts are soft enough." winked Naruko leaning down and mashing her breasts around Naruto's cock.

"T-they are-!" Naruto gasped as he felt like cumming right away.

"You sure~?" sang Naruko taking the tip in her mouth as she began to rub the cock with her breasts faster.

"Y-yes!" Naruto said near his limit.

Naruko smiled and held her head down as Naruto's cock twitch and began to fill her mouth with sperm.

'Mmmm...tasty~!' She thought as she drank her brother's semen.

She popped her mouth off and saw Naruto panting from the technique.

"Was I good or was I good?" Asked Naruko with a smirk.

"Really...good." panted Naruto.

"Good! Now let's go to the main event~!" Chimed Naruko with a grin. She pulled back and laid on her back as she pulled her pussy lips open.

Naruto gulped before he asked her, "Are you sure?"

"Push it in and find out." grinned Naruko.

Naruto chuckled before he put his penis in position and began to enter his sister's vagina until he got to her hymen.

"You're still a virgin?" whispered Naruto in surprise.

"O-of course I am, dummy! I would only give myself to the one I love!" She answered with a blush.

That made Naruto's jaw drop as Naruko looked sad that he didn't realize it sooner.

"...Since when?" He finally asked.

"Well, I started getting a crush on you when I was in middle school. She said with a blush.

"I-I see..." Naruto said before preparing himself, and trusting with full force, tearing apart her hymen.

She gritted her teeth and hugged dug her nails in Naruto's back from the pain.

"So...tight!" He gasped as he felt his sister's insides trying to milk him dry.

Naruko moaned as Naruto pulled back before slamming in balls deep.

'So...big!' Gasped the blonde girl as she felt her brother's shaft piercing her and give her more pleasure than before.

He gripped her hips as he continued to pound into her tight pussy which felt like it didn't want to let go of him.

Naruko meanwhile was feeling like she was in heaven from all the pleasure she got from her brother fucking her senseless!

He held nothing back and kept moving his hips back and forth while slamming into her at a rhythm that kept the girl barely able to moan out loud.

Then Naruto grabbed with his hand his sister's bare breasts and played with them, making her moan.

"Go on Otouto, play with your slutty sister's breasts." moaned Naruko bucking her hips against his groin for each thrust he gave.

"Man...you love this, don't you?!" Grinned the blonde as he sucked her breasts while piercing her.

"Yes! I use some our pictures together to masturbate! I've always wanted this!" cried Naruko feeling amazed at how her body tingled under her brother's touch.

Naruto blushed in embarrassment as he thought 'What a pervert! Did Ero-kyofu (Jiraiya) corrupt her?!' before continuing his love making.

Both of them moaned and panted as Naruto began to feel his dick start to twitch inside her.

Shit! I-I'm gonna_!" Warned Naruto as he tried to take off his dick from his sister, but the latter's legs kept him from pulling out!

"Inside! Don't you dare pull out!" screamed Naruko hugging Naruto closer to her body.

"B-but if you do that, I-"

"I don't care! I want you to fill my womb with your sperm!" moaned Naruko.

Naruto tried to say more, but felt himself coming and thus with a curse he came inside his sister's pussy, painting it white with his sperm.

Naruko cried out in bliss as she felt the hot sperm fill her up.

'Finally...I'm...Otouto's...' She thought in pleasure.

Both of them laid there panting from their session as they held one another.

"How...was that?" Naruto asked.
