Loud and fast footsteps were heard from inside a giant castle looking mansion in a hallway.
"Haha Onee-chan you can't catch me!" Said a male child-like voice as he ran away from someone.
"I swear when I get my hands on you!" An angry female voice responded as she chased after him. These children were none other than Naruto Gremory and Rias Gremory.
Rias Gremory was Naruto older sister by 5 years. She is currently 13 soon going to be 14 next year and attending an academy called Kuoh Academy after her birthday with her friends who are Akeno Himejima and Sona Sitri.
She now currently stood 5'4 taller than Naruto who is currently 4'2, she is slightly taller than the average female for her age. She has white skin, blue eyes and currently a developing figure that was bigger than average for her age and the most distinctive part about her, is her long beautiful crimson red hair that reached her lower back stopping slightly above her hips with a single strange of hair sticking from her top. Her hair also has loose bangs covering her forehead and side bangs framing her face. Both her and Naruto had inherited their red hair from their father who is Zeoticus Gremory who is currently the head of the Gremory clan.
Naruto had spiky red crimson hair, blue cerulean eyes and 3 whisker-like marks on each side of his face that he was born with. Naruto is currently 8 years old and was a naturally born prankster with high amounts of energy. Now he was currently running away from his furious sister because he had earlier painted her gundam figures the color of red and scribbled on her one piece manga. He too shared the love for anime as his sister as they would cuddle up on either her bed or his where they would usually have a snack with them as they watch anime together being Otaku's. Naruto knew that drawing on one's manga is a horrible offense especially and Otaku.
Naruto was currently running down the hallways making sure to take tight turns to avoid wasting time and made sure that his sister did not catch him. But something strange happened, while he was running he did not hear footsteps coming after him anyone which made his confused. He slowed down and turned around only to see that his sister was not there and that caused him to get worried.
"Onee-chan? Where are you?" He asked in a concern voice as he retraced his steps to look around for his sister. He checked the places he passed by only to come up empty so he went over to his sister's room to check if she was in her room angry with him. This caused Naruto to feel a slight pain in his heart and nervousness as he merely intended this prank to be a joke and he did not want his sister to be mad at him. Growing up their older brother who goes by the name of Sirzechs Lucifer instead of Gremory is because he had been picked to become one of the four maou specifically lucifer due to his help in the devil civil war with the old devil faction where he met their now sister-in-law on the other side of the battle field who harbored feelings for him overtime. Her name was Grayfia Lucifuge the self proclaimed servant of the Gremory house. She would usually dress up in a maid outfit and serve Sirzechs as his queen.
Sirzechs was currently doing paperwork in his office while Grayfia was there to make sure that he actually did the work and not sneak home to dote on both Naruto and Rias. Did I also mention that he was a huge sis-con and bro-con? As long as Naruto could remember, Sirzechs would dote on him like he did with Rias giving them anything and everything they wanted and shower them with affection. While they both were grateful for the affection they were slightly irritated by his childish behaviors.
Currently Naruto had arrived at the entrance on Rias's room as he opened the door and peered inside the room only to see anime related stuff whether be it manga, figurine or anime they were all there. But there was no sign of Rias in her room.
"Onee-chan?" He called out sounding even more worried that he had been just now as he could not find his sister.
What he did not notice was someone sneaking up behind him and that figure slowly crept towards him making sure not to make a single sound as it raised it's hands up over him like a predator before it swooped down.
Naruto was surprised when a pair of arms wrapped around his waist causing to him squeak in surprise before it became laughter at the figure started to tickle his tummy continuously. Naruto tried to hold back the laughter but he couldn't.
"Hah! Your Onee-chan tricked you!" Said Rias as he continued to tickle him as she heard his laughter before he stopped and his body fell limp causing Rias to catch her brother in her arms.
"Huh?" Rias looked confused as she brought his face up only to see him what looked to be unconscious.
"Hey Naruto-kun wake up." She said irritatedly as she poked Naruto's face wanting to wake him up as she thought that Naruto was just faking it but to her surprise he did not seem to respond.
"Hey this isn't funny anymore Naruto-kun wake up!" Rias tried again but this time lightly slapping his face only for the same response to happen. This caused her to panic as she carried him in a bridal carry and she sprinted to find their parents.
"Don't worry Naruto-kun, I will find kaa-chan and tou-san!" She said as she blitzed through every room as fast as she can while making sure to do it carefully not to injure the unconscious Naruto.
After several more minutes of sprinting Rias sees their parents at the meeting room and they seem to be discussing something about her from what she could hear she ignored that and burst into the room shocking her mother and father thinking a intruder broke into the room. They prepared spells and were about to fire them but noticed Rias.
"Oh hello Rias how can I hel-" Her mother greeted her only to stop when she notices the unconscious form of Naruto in her daughter's arms causing her to quickly rush towards their children and stopped in front of Rias and crouched down to Naruto's head level as she examined him. She was Venelana Gremory formally known as Venelana Bael but she changed her clan name when she married Zeoticus. She has flaxen hair that reaches down her shoulders with two bangs on the side of her face and a few more in front of her head. She also had violet eyes which is a common trait in the Bael clan, she looked to be in her twenties with a huge bust.
"Rias what happened to Naruto!" She demanded to know only for Rias to gulp.
"We were just playing and I was tickling him and the next thing I knew was that he lost consciousness." She quickly said as she noticed that her father was by her side ready to use a teleportation spell to the hospital for Naruto to be treated. A blinding red circle with the Gremory clan symbol in the middle of it. The next second a red blinding light engulfed the room and then the next second they were gone.
(At the hospital)
While Rias and Zeoticus patiently and anxiously wait for the doctors to come out of the patient room to inform them about Naruto's condition Venelana was pacing down the hallway while biting her nails anxiously.
"Why is it taking so long?!" Venelana snapped as she had been waiting for over an hour and they still haven't gotten a response from teh doctors about how her baby boy is doing. Was he fine? Is his condition serious? Was he going to be okay? Were just the few thoughts that ran through her head as she anxiously continued to pace up and down not caring about her husband's attempts to try and calm her down.
Suddenly a doctor opened the door to Naruto's room causing Venelana to instantly appear in front of his face.
"How is my baby boy doing?! Is he fine?! What happened?! ANSWER ME DOC!" She frantically said and snapped when the doctor did not reply.
"Uh honey I think you should stop shaking him…" Zeoticus advised sweat dropping as he watched his wife shake the poor doctor as he could see rings around the doctor's eyes.
Venelana heard what Zeoticus said and released the doctor from her grasp but not before glaring at the doctor.
The doctor took a moment to catch his breath and smoothen out his coat before looking at the family in fear especially Venelana.
"Gremory-sama, Naruto-sama is fine he had just lost consciousness thats all." This made the family let out a breathe that they did not even know they were holding after hearing that Naruto's fine.
"But." The doctor continued after letting them have their moment of relief. This caused everyone to listen attentively.
"The reason your child has lost consciousness is because of a condition." This caused everyone to be confused as Naruto was always healthy sometimes maybe even too healthy. Hearing that Naruto had a condition definitely surprised them.
"What is the condition doctor-san?" Venelana asked in a calmer voice than before but if you listen close enough you could hear the worry in her voice as she asked the question.
"We found out the reason why Naruto-sama lost consciousness is because of a condition that only he has that we currently know of as this is the first in any record of this happening." The doctor explained causing the family to hold a breathe in worry as being the first for any condition was usually not a good sign.
"What is that condition?!" Venelana urged the doctor to finish which made him sigh.
"The condition is that he has not release." The doctor's explanation caused then to look at him confused.
"Release? What do you mean?" Zeoticus asked the doctor.
"I mean that Naruto has not release the sexual drive in his body causing him to faint due to the amount of sexual tension in his body. From what I could see he was born with over average amount of libido." The doctor explained causing the family to worry.
"What would happen if Naruto-chan doesn't 'release'?" Venelana asked worriedly.
"If Naruto-sama doesn't 'release' three times a day, he would faint but when he grows up this would cause severe damage to his body and he might die." The doctor finished with a somber tone as everyone in the family gasped at the consequences if Naruto were to not 'release' three times a day.
"Can we go see him?" Was Venelana's next question as she voiced everyone's thoughts.
"Of course Gremory-sama but I must warn you that he is currently still unconscious. We estimate that he would wake up in a day or two." The doctor finished before he bowed to them and walked away.
This cause everyone to break out of their shock as they started to walk towards the door to Naruto's room. Venelana opened the door to see a normal looking hospital room and a hospital bed where Naruto was currently on.
They walked towards his unconscious form as they looked over him sadly. While Rias was standing near Naruto's left head as she stroked his crimson locks. Venelana sat on the chair provided by the hospital at his right hand side of the bed while Zeoticus stood as the end of the bed.
They watched as Naruto's chest rise up and down in a trance.
"Rias-chan." Zeoticus called out his daughter making her turn towards him.
"Yes tou-san?" Rias asked curiously.
"I need you to stay with Naruto for now as me and your mother has stuff to discuss on Naruto's condition." Zeoticus responded where Rias nodded as he looked towards his wife seeing the stubborn look on her face telling him that she would not leave this room.
Zeoticus sighed as he held her hand and started to pull her out of the room and after some failed attempts, Venelana albeit begrudgingly as she let him lead her out of the room but not before she catch a glimpse of Naruto's unconscious body and left the room.
"What do you want to discuss Zeoticus-kun?" She asked with annoyance something that Zeoticus could hear. Making him sigh as he rubbed his head.
"Do you think we should hire maids to take care of Naruto's condition?" Zeoticus asked which made. Venelana contemplate on whether or not ask maids to take care of her baby boy.
"I don't know dear, maybe we should ask Naruto-chan when he wakes up?" She suggested making Zeoticus nod in agreement before he pulled his wife into a hug making her bury her face into his chest and he soothingly rubbed his hands on her back.
"He will be fine dear." Zeoticus tried to comfort his wife.
"I know." Was all she said as they basked in the silence for a little while enjoying the other's comfort before they eventually went back inside the room.
(Timeskip)
'Huh? Where am I? Why is it so bright?!' Were the thoughts of Naruto as he groggily woke up from his nap and he opened his eyes only to notice that he wasn't his room. 'Huh?' He looked around the room and concluded that he was in a hospital private room if the equipment around the room told him anything.
'Why am I here? I remember pranking Onee-chan then she stopped chasing me. I searched for her in her room but she came behind me and started to tickle me. Why is it foggy after that? Why can't I remember anything?' Were the thoughts from Naruto but he was pulled back into the world when he heard groaning coming from the left side of his bed.
Confused Naruto looked at his left only to notice the distinctive long beautiful and silky crimson red hair that he loved so much. He watched as his onee-chan started to stir awake as she rubbed her eyes while she adjusted to the light.
After she rubbed the sleep off her eyes she noticed that Naruto was tilting his head at her direction with a confused expression on his face. It took all her will power to not gush over Naruto and squeeze him in a tight hug while cooing about how cute he was.
'Wait? Naruto is awake!' She came into realization that Naruto had finally woke up and she jumped out of her seat and pulled Naruto into a tight hug.
"Your awake! Your awake!" Was what Rias kept repeating as she rubbed her cheeks against Naruto's making him purr as his cheeks especially his whisker marks are hyper sensitive. When his cheeks were rubbed they would usually cause him to purr like a feline something that Rias accidentally found out when she was curious about how his whisker marks felt like.
This caused Naruto rubbed his cheeks against hers liking the sensation of him purring.
After a few more minutes of hugging Rias finally let Naruto go as she climbed out of the bed.
"Wait for me Naruto-kun, I am gonna tell kaa-san and tou-san that you are awake." She chirped as she immediately bolted out of the room not letting Naruto ask the important question which was why was he here in the first place.
Naruto sighed as he waited for his parents and onee-chan to come back into the room as he fidgeted with the hospital sheets to get his mind off wandering as he waited.
After a few more minutes the door burst open as Venelana came through it as she immediately went up and hugged Naruto pushing his face into the valley of her cleavage.
"Oh my baby boy! You are awake!" She said as she gushed over him as Naruto started to flail his arms trying to escape from her 'pillows' as he was starting to lose air.
"Uh honey… maybe you should let Naruto-kun breathe?" Was the deadpan response from Zeoticus as he noticed Naruto's face was turning blue.
After some reluctance Venelana let Naruto go causing him to take a deep breathe trying to recover the lost oxygen.
After steadying his breathing while silently cursing his mother's great 'pillows' and how they almost killed him. It would be the greatest way to die but Naruto was too young to not experience things in life before he died.
"What happened?" Was Naruto's question as he recovered his breathing.
"We were discussing politics when all of a sudden Rias rushed into the room carrying your unconscious body. We immediately brought you to the hospital." Venelana summarized as she looked at her baby boy in concern.
"Why was I unconscious?" Naruto asked making Venelana and Zeoticus to sweat as they wanted to explain the 'bird and the bees' to him in a few years time but apparently they had to shift it to now.
Venelana and Zeoticus looked at each other having a silent conversation between their eyes about who was gonna explain the 'bird and the bees' to him.
In the end Venelana sighed as she decided it was best for her to do it as her husband would probably fill Naruto's innocent mind with bad thoughts.
"Okay Naruto-kun the reason why you were unconscious is because…"
(Timeskip)
Naruto kept blushing as he thought about how his mother explained the 'bird and bees' to him. He noticed Rias coming through the door and couldn't help but blush as he now knew why every time when Rias slept with him naked his 'rod' would get extremely stiff causing him to shift around uncomfortably as he tried to sleep.
Rias wondered why Naruto was looking at her while blushing making her confused before she just shrugged and walked over to Naruto's bed.
"Are you feeling okay?" Rias asked in concern for her younger brother.
"Y-yea onee-chan…" was the response Naruto gave as he tried to fight off the dirty thoughts about him and his sister who just looked at Naruto in question.
"Can we go home now onee-chan? I don't like being in a hospital." While normally Naruto feared little things but sharp pointy needles were something that scared him to death, ghost as well.
"I think we should be able to bring you home now." Was the simple reply he got from Rias as Naruto got off from the bed and they walked outside of the room to see their mother and father talking to the doctors about something.
They shrugged before walking over towards the chairs to take a seat and wait.
As Naruto was about to sit beside Rias, she pulled his wrist towards her as she sat down onto the chair with him on her lap as she started to play with his crimson locks.
Naruto was blushing a little bit as he could feel Rias chest pressing against his back and he could feel the softness of them.
After about half an hour, their parents have finished talking with the doctor as they walked over to Rias and Naruto intending to take them back home.
"Ok lets go Naruto-kun and Rias-chan." Venelana said as they were covered by a blinding light teleporting back to the mansion.
"Naruto-kun make sure you 'release' three times a day alright? Make sure you don't forget it." Venelana sternly said to Naruto who quickly nodded as he went into his room going to sleep after the traumatizing story his parents told him.
Rias looked in worry as a small blush crept on her face as she knew what her parents meant by 'release' as they had given her the talk a few months ago.
Sighing Rias walked back towards her room and came to a stop at her door when she noticed that two signatures were inside the room. She continued to walk in not caring one bit as she recognized the signature to be her rook and queen.
She walked in to see a female about her age but had a bigger figure than her which usually made her jealous. She had black hair tied into a long ponytail by a orange ribbon that she got from Naruto. She has violet eyes, this was Akeno Himejima, Rias's queen of her peerage and her first servant.
Next was a small petite white hair female and gold eyes, she was sitting at Rias round table in the middle of the room in front of the huge tv where she watches anime on, while munching on some sweets. The front of her hair has two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back has a short bob cut. She also wears a black cat-shaped hair clip on both sides of her hair. This was Koneko Toujou. Rias's first rook and second member of her peerage. She was 2 years younger than Rias and Akeno.
"Ara? Rias where have you been?" Akeno spoke up when she noticed Rias entering her room. She was currently lying on Rias's bed on her stomach as she kicked her legs.
"Naruto fainted so we had to bring him to the hospital yesterday." Was Rias reply as she walked over towards her bed and stripped naked and flopped on the bed.
"Ara? What happened to Naruto-kun? Was he a bad boy, do I need to punish him Rias~?" Akeno slurred in a dreamy voice as she brought her hands up to cup her cheeks as her cheeks were flushed as she thought about punishing Rias little brother and how he would moan in pain.
While Akeno was in her fantasy Rias had a frown on her face full of jealousy at the thought of Akeno being close to Naruto. 'Stay away from him you sadist!' Was the thought that ran through Rias mind as Akeno took pleasure in inflicting pain on others or herself.
"Oi! Don't go stealing my Naruto-kun!" Rias possessiveness towards Naruto came out making Akeno smirk teasingly.
"Ara? Is Rias so greedy that she keeps Naruto-kun all to herself? I am sure Naruto-kun would be quite handsome when he grows up, so why not share him?" Akeno teased with a dreamy smile on her face as she imagines what Naruto would look like when he grew up.
"He is my little brother not yours!" Rias defended herself getting increasingly more jealous as Akeno continues to tease her.
"Ara? I am sure Naruto-kun likes bigger breasts Rias." Akeno cups her breasts and squish them together to state her point making Rias look down at her cursing herself for not growing bigger than hers.
"I might not be as big as yours but I am sure Naruto-kun likes red hair more than black." Rias proudly stated as she ran her fingers through her hair.
The comment made Akeno's eye twitch in annoyance as a tick mark appeared on her head.
"Ara? We will see who Naruto-kun prefer Rias." Akeno admitted defeat as she stripped naked and join Rias on her bed. Koneko stayed silent during their conversation but when they mentioned about their sizes she could not help but look at her flat chest in disappointment. Silently wondering why she was so small and wondered if she would grow bigger when she grows up. She wondered if a certain black hair cat was flat as well.
(Somewhere else)
A certain busty black cat wearing a black kimono that revealed quite a bit cleavage sneezed.
'Huh? Is my little Shirone-chan thinking about me nya?! I knew Shirone-chan loves me nya!' She thought in happiness as she walked towards a small petite girl with black hair, her outfit consisting of a black Gothic Lolita outfit.
"Hurry up cat we need to go somewhere." The lolli said as she turned around and started walking to the exit of the facility they were currently in.
"Hai! Ophis-sama nya!" The black haired cat chirped as she skipped after the lolli.
(Timeskip 4 days later)
It was a dark night in the underworld as Rias was currently walking through the hallway of the Gremory mansion after a tiring day of playing chess with Sona.
Sona sitri was the heir of the house of Sitri and is the childhood friend of Rias. Sona was smarter than Rias but she was too prideful to admit so she made Sona her rival. Rias would challenge Sona to a game of chess,occasionally winning some and losing some.
Rias was walking and noticed that Naruto's room door was currently open and a small light was coming from the room.
Rias wanted to see what her little brother was doing so she crept towards the door making sure not to make a sound.
She peered her head into the room and was about to call his name but her throat went dry as she watched as Naruto stroke his member while facing her photo which was kept in a picture frame.
"Onee-chan~! Ah! It feels so good! Onee-chan~!" Naruto shouted as he came onto the picture frame of Rias squirting his cum all over her photo.
Rias started blushing and her body heated up as she listened to what seem like Naruto jerking off to her. This made her warm inside as she watched the scene.
She grew concern when she notice that Naruto seemed to flinch every time he stroke his dick. Squinting her eyes to focus further she noticed that Naruto's hand seem to be covered in blisters.
Naruto was currently panting and groaning in pain as he tried to stroke his dick but it hurt every time he tried to touch it. His hands felt like they were on fire and the pain grew harder to tolerate.
He was about to try and stroke it again but before he could a hand grabbed it and started to stroke him. Causing him to quickly spin his head and he came face to face with Rias.
"O-Onee-c-chan?! W-what a-are you d-doing?!" Naruto stuttered in surprise and shock before letting out a moan feeling the pleasure running down his body as Rias continued stroking him with her silky smooth hands and occasionally using her palm to rub his tip.
"Shhh just relax and enjoy it Naruto-kun." Was Rias reply making Naruto relax a little bit as he moaned again as Rias started to speed up her strokes.
O-Onee-chan if y-you g-go that f-fast I will c-cum." Naruto moaned out making Rias smirk as she accelerate her strokes making Naruto start to twitch.
"Ah! I am cumming!" Naruto shouted out as he came onto Rias's hands covering them with his semen.
'Wow so much, the smell is so strong!' Rias thought in surprise as she brought up her hand to take a whiff of his cum noticing it has a strong musk smell. Deciding to give it a lick she noticed that it tasted a little salty but not too much that she hated it.
'Mhm~ it's not bad.' She mused as she sucked and licked his cum off her fingers making them shiny with her saliva.
Meanwhile Naruto was currently panting after he had just released. The amount of pleasure he felt when Rias started to stroke him was leagues beyond anything that he has ever felt in life.
Rias finished cleaning her fingers and look back at her little brother and she could see a large blush on his face and the ragged breathing. She also noticed that his rod was still standing proud something that made her smirk.
She started to strip her clothes off and brought Naruto onto her lap earning a squeak from him.
She pressed her breasts against his back and grabbed a hold of his dick and started to stroke it again.
"Is Naruto-kun feeling good from getting jerked off by his old sister? Who knew Naruto-kun was so naughty~" She said in a sing along voice as she slowly stroke his dick while she lick his ears and fondle his balls, making him moan at her ministrations.
"Ah! It is just that, Onee-chan hands feels good!" He tried to defend himself from Rias teasing but it was for naught as he moaned again when Rias tweaked his hardened nipples.
"You say that but you are a moaning mess." Rias continued to tease him as he shivered when she blew into his ear.
"Ah! I am cumming again!" Naruto shouted out as he fired another load onto her hand.
Doing the same actions she did before, she brought Naruto onto the bed as she lied on her back as she spread her legs giving him a clear view of her dripping wet pussy.
"Have you seen one before?" Rias asked as she pointed to her lower lips making Naruto gulp as he watched the juices flow down her ass staining the sheets.
"N-no." Naruto stuttered in wonder as he reached out his index finger and went to poke the dripping pussy earning a flinch and moan from Rias.
Naruto looked up at Rias face and noticed that she was enjoying it a lot. Naruto continued to poke her pussy earning more gasp of pleasure. After more poking, he noticed a thin string of sticky liquid was on his finger. Being the curious boy he was he gave it a experimental lick. He tasted a small amount of taste roses something that he found fitting for her crimson hair.
Deciding he wanted more, Naruto dived into her pussy and started to lap the juice coming from it. This cause Rias to wrap her legs around his head while pushing him deeper with her hands while she turned into a moaning mess.
"Ah! That's it Naruto-kun! Deeper!" She moaned out, Naruto following her orders he pressed his tongue deeper into her folds feeling her insides squeezing his tongue and how hot it was.
"Ah! I am about to cum!" She said making Naruto faster his ministrations. He pinched her clitoris making her cum as she sprayed it all over Naruto's face as he kept lapping up the juices.
After she finished cumming she started to pant heavy breaths coming down from her high with her face being flushed.
She smiled at Naruto as she noticed him enjoying the taste of her.
"Naruto-kun, come here." She gestured making Naruto climb towards her. She sat up and spread her legs again to give him another clear view of her pussy as she spread them apart with her fingers.
"Naruto-kun, if you put your dick inside this hole it is said that it is the most pleasure a man could experience." She explained as she pointed towards the hole Naruto was suppose to enter.
"Pleasure…"Naruto muttered as he stared at the hole. He guided his dick towards the entrance and he watched as his dick slowly disappeared into the hole. Naruto moaned when he entered her folds as the amount of heat radiating from her felt so hot that he was burning but the tightness of her insides coiling around his dick felt like he was gonna be crushed, and that is not mentioning the wetness inside her.
Naruto slowly slipped even more of himself inside of her until he hit a wall.
"Onee-chan, why do I feel a wall?" Naruto asked his sister who was currently clenching her teeth not trying to moan.
"T-that is a hymen, it symbolizes a girl virginity, their most precious part." She explained making Naruto look at her in worry.
"Are you sure you want me to take your precious part?" Naruto asked worriedly not wanting his sister to lose it to him. His concern made Rias smile finding it rather cute her little brother was asking for her consent.
"Of course Naruto-kun, you are the only male who can do this with me." She said as she loving stroke his cheeks reassuring him of her decisions.
Naruto nodded before she thrust her hips against his breaking her hymen causing her to let out a pained scream.
"Onee-chan! Are you okay?!" Naruto asked in concern not liking the idea that he had caused pain towards his older sister. Blood started to leak out from her pussy and around his cock when he took her virginity.
"I-Its f-fine N-Naruto-kun, j-just give m-me a m-moment." She gritted out in pain as she took deep breaths trying to focus on something else besides the pain. After a while she started to gyrate her hips trying to subdue the pain with pleasure.
Naruto gritted his teeth as he tried not to thrust his hips no matter how much pleasure he was currently feeling as his sister's health was more important that pleasure.
"You can move now Naruto-kun." Rias said making Naruto nod as he slowly pulled his dick out leaving only the tip before he push it back in causing both of them to arch their backs in pleasure.
Naruto continued to actions but gradually started to pick up speed.
"Ah! It feels so good Naruto-kun! Please deeper and harder!" Rias moaned as Naruto started to thrust his hips harder and deeper into her.
"Ah! Onee-chan! Your insides feels so good!" Naruto screamed out as he laid his face onto the valley of her breasts and wrapped his small arms around her waist as he continued to thrust into her.
After a few more minutes of Naruto thrusting they were close to their climax as Naruto started to twitch inside Rias while she was tightening herself around him.
"Onee-chan, I am about to cum! Where do I do it?!" Naruto asked as he fastened his thrusts.
"Ah! Do it inside!" She screamed aloud as Naruto slammed his hips as hard and deep as he could into her as he released his seed into her womb. This caused Rias to arch her back as she came, their juices mixed with one another as it overflowed and leaked onto the bed.
Naruto did some light thrusts to made sure he had emptied it all before pulling himself out as he flopped onto her breasts panting hard.
When Naruto pulled out, Naruto's cum started to spew out of Rias as it flowed down her ass cheeks and stained the bed sheets.
After a few moments of silence besides their loud intake of breaths, Naruto decided to speak up first.
"Wow Onee-chan, that felt really good!" Naruto exclaimed in excitement.
"Thats good Naruto-kun, it felt really amazing for me as well." Rias said with a smile on her face as she hugged Naruto, causing him to snuggle deeper into her breasts liking the sensation off her soft 'marshmallows' around his head.
They both basked in the silence enjoying the other's embrace. But all things came into an end when they heard a cough coming from the door.
"Ara Rias, who knew you had the guts to have sex with your little brother? Ara what a naughty Rias." Said a sultry voice with a hint of lust.
