Chapter - 10

Thanks for Itachi_Hyoudou76 for the shout out in his book "Ultimate DxD" I really appreciate it.

[A/N: -He doesn't use his presence detection all the time. He is using it as a passive towards hostile and foreign entities. Those that are connected to him or he sets as family/friends are ignored by it. That's why Saeko and Co could sneak inside his bed without him waking up.

Also, cringe alert.

P.s Minor R-18 content, not smut though.]

____________

Inside the Oukami mansion, the young Primordial was currently chilling in the living room while playing his recreated version of Assassin's Creed I after he left Medea to do whatever she wants. He felt thankful to whoever gave him the ability to recreate his favorite games with realistic graphics and supreme mechanics overall, all of his otaku wishes have been fulfilled, he felt like crying from happiness.

While he was engrossed in his game, he didn't notice the presence that kept getting closer to him until 'it' jumped on him.

"NII-SAMA!!"

The one who jumped on him was an extremely beautiful young lady, she has dark brown hair and blue eyes, she was wearing the Homurahara school uniform that couldn't hide the charm of her E-cup breasts.

He caught her in his arms and spoke with a smile.

"Welcome back, Sakura-chan. How have been your day at school?"

Yes, the one who jumped into his hug is Oukami Sakura, formerly known as Matou Sakura and Tohsaka Sakura.

Sakura ignored his question as she kept hugging him tightly and sniffing him.

"*sniff*sniff*sniff* Nii-sama's smell. I have been missing it all day. I need to replenish my Nii-samanium."

Jin couldn't help but smile wryly at the antics his perverted 'little sister', he then started patting her head, while she closed her eyes in bliss.

A couple minutes later, Sakura lifted her head from his chest while still hugging him and spoke.

"Same as always. However, the girls from the club wanted to come and visit you since you are supposed to be sick."

Sakura muttered darkly as she looked at her beloved Nii-sama.

She then noticed something different on her Nii-sama's hand.

"Nii-sama, did you ditch school today to get a tattoo?"

Sakura questioned as she pointed towards his newly acquired [Command Spells] that he got after his contract with Medea.

"Oh, this? You are not entirely wrong, but this is not a normal tattoo, but [Command Spells]."

Jin spoke as he moved his right hand closer to her face so she can see it better.

[A/N: - His command spells either look like a Phoenix or Ouroboros.

I actually wanted to use the Ouroboros as the shape to represent the 'infinite' number of times he can use the spells but thought that a phoenix would look kinda cooler and since it can go through 'rebirth', so the spells will still regenerate, so we are good.

Since I have no problem with either, you guys choose whether it's the Phoenix or the Ouroboros.

Phoenix

or

Ouroboros.]

Sakura traced the command spells with her fingers and then spoke quickly with a serious tone.

"Are you going to participate in this war? You won't stay neutral this time? Have you already summoned the servant? Are they strong?"

Sensing the worry in her tone, he stared patting her head again as he spoke.

"Yeah, I am going to participate in this war. I have zero interest in the Holy Grail though, I just want to have some fun and fight some historical characters. I have formed a contract with Caster that I saved before her spiritual body dissipated at the foot of the hill near the mansion."

Sakura ignored all of his speech about fighting legendary figures for fun as a certain word caught her attention.

"Her?" (Sakura)

"Yeah, Caster is a woman." (Jin)

"Did she tell you her True Name?" (Sakura)

"Yeah, she is Medea, the Princess of Colchis."

"What?!"

Hearing the name, Sakura jumped out of his hug and looked at him with a stern look.

"Why did you contract her?! Isn't she the Witch of Betrayal?! And why was she near this place with no master in the first place?!"

Sakura was practically shouting when she heard about Medea.

"Calm down, Sakura-chan. Well, she killed her master and fled." (Jin)

Sakura who heard his response became even more furious!

"Then why did you make a contract with her?! You just said that she killed her previous Master!"

Seeing that she was on the verge of crying, Jin stood up and hugged her.

"It's ok, Sakura-chan. She is not a bad person."

Jin spoke and then his voice became soft.

"Besides, calling her a Witch is not appropriate. You have read her story, right? All I can see is a pitiful girl who became the victim of a slut that took a liking to an asshole.

She was cursed to love someone who she didn't even know his face, she had to kill her own brother and cut his body and throw him in the sea, she helped the man she was cursed to love to reach great heights just to be discarded as a useless tool and being labeled a witch at the end.

You see, she was just a victim just because she had some talent, and a horny Goddess took a liking to someone. In that case aren't you a bit similar?"

Jin spoke with a soft tone while caressing her back.

"How?"

Sakura had a hunch of the answer but still asked.

"Weren't you in the same situation before? Wasn't Matou Zouken about to force you into that disgusting torture because of his obsession of making an heir capable of winning the Grail?"

"But Nii-sama saved me!!"

Hearing her, he smiled a bit.

"Nii-sama saved you because you were lucky. However, she didn't have someone to save her. Sakura-chan, you consider me as family, right?"

"Of course, Nii-sama! You are my only family!"

Sakura said with convection.

Jin smiled wryly at her answer. She still doesn't want to accept Rin as her sister. He continued patting her as he spoke.

"Now imagine this, Zouken cursing you to be obsessed with Shinji and love him more than anything, just so you can help him steal something from my workshop. After that, you had to kill me and even cut my body apart to avoid pursuers. In the end, no one appreciated your love, and you were discarded and branded as a witch. It's sad, right?"

Jin told her with a soft voice.

Sakura who heard him, played the scenario in her mind and her face became deathly pale as her body started shivering and tears came out of her eyes.

"N-N, I don't want that!"

She practically screamed as she hugged him tighter.

"Silly girl, don't worry. Didn't your Nii-sama tell you that he will protect you? I am pretty strong you know."

Jin told her with a smile as he hugged her shivering body tighter and wiped her tears.

"Un. Nii-sama is the strongest."

"Hahaha yes, your Nii-sama is the strongest!"

Jin told her with a small chuckle.

They stayed like this in a comfortable silence for a while, then Sakura spoke.

"Nii-sama, I will try to get along with her. HOWEVER! If she ever tried to hurt you in any way, I swear even if it results in my death that I'll kill her!"

Sakura spoke with a tone of stating a fact that will never change no matter what.

"Baka imouto, you know that I'm strong enough to singlehandedly win this war and come out unscathed right? You don't need to worry. And I don't really think that she will do anything to harm me, she may seem scheming and evil outwardly, but she is really soft on the inside. Besides, even though I have no interest in the Grail, she can use it if she wants. Her wish is to avoid the tragedy of her past after all." (Jin)

"Un."

Sakura nodded as she enjoyed the warmth of his embrace and stayed in his hug for a while.

What they both didn't notice, was a woman with blue hair that had tears after listening to their conversation.

Medea who had finished erecting a barrier around the mansion came back to hear the conversation her Master was having with his 'little sister'. At first, she was angry after being called a witch by Sakura, but something inside her told her to wait and listen to her Master's reply first.

She was not disappointed. His reply filled her with warmth that she didn't feel in her entire life.

She dematerialized herself as she left them alone with a newfound determination to win the Grail. However, this time is not to change her past like she had always wanted. It's to preserve this sense of warmth for a while longer even after the war ends.

____/Scene Change\____

Jin was now in the kitchen with Sakura preparing dinner when he suddenly received a telepathic message from Medea.

"Master, is it ok to materialize in front of her?"

"Yeah, no problem, she knows about the war."

After she received the permission, Medea materialized near him, startling Sakura.

Sakura recovered and spoke.

"So, this is your servant, Nii-sama?"

"Yes. Medea, this is my little sister, Sakura. Sakura-chan, this is Medea, a Caster Class servant. I hope you get along."

Sakura grimaced a little when he introduced her as his little sister, which Medea sensed and smirked under her hood.

Sakura and Medea then stared at each other for a while with sparks going between them. Jin was lazy to bother with them as he was thinking that his handsomeness is unfair to the world.

After a while Medea thought of something as she smirked, which gave Sakura a slightly bad feeling.

Medea went and hugged Jin's arm and buried it in her breasts as she spoke seductively in his ear while looking at the fuming Sakura.

"Master~ Can you teach me how to cook? The dishes you made for me today were delicious."

Jin kept stoic face and kept cooking. However, his inner thoughts were that Medea's breasts feel great, but they are 2 centimeters smaller than Saeko's.

Sakura seeing this was angry, but she remembered something and looked with a victorious smile. She hugged his other arm and spoke.

"Nii-sama, I'm tired from the archery practice today, can you please give me a massage like usual."

Sakura spoke and emphasized on "usual" to irritate Medea even more.

Jin also ignored her and compared her boobs with Saeko's. 'They are about the same size, but Saeko's breasts are firm while Sakura's are so soft like marshmallow'.

"Ok, enough fighting, now go prepare the table. And Medea, you can go to your room and wear some comfortable clothes at home, wearing a robe all the time is not really practical."

They both gave each other another and left to prepare the table and Medea left to change her clothes after that.

Seeing that they both left Jin sighed at his life a harem protagonist.

'Only a month remains till I finally swipe my V-Card! I can't wait for Saeko to come out, I am not a saint and want to eat them, but Saeko will be first.'

After a while they were all ready to eat. This time Medea was prepared and started eating slowly.

Sakura however was eating with mixed emotions.

"Sakura-chan, what's wrong? Does the food taste bad?" (Jin)

"No, it's extremely delicious as always, Nii-sama. It's just..." (Sakura)

"Hmm?" (Jin)

"My food can't compare to you, Nii-sama. No matter how much you teach me it doesn't taste nearly as good as yours. It's a major damage to me as a woman." (Sakura)

Jin who heard her reasoning burst out laughing.

"What are you laughing at, Nii-sama?!"

Sakura shouted from embarrassment.

"Ahahah, sorry sorry, but you looked really adorable, Sakura-chan. However, your cooking is really great, and I really love it."

Jin told her with a smile.

"Really?"

Sakura who heard her beloved Nii-sama's praise was on cloud nine.

"Yes, really. Don't I always ask you to make my bentos? I am always cursed to death by the other guys you know."

Jin spoke and Sakura giggled happily.

Medea who was watching their interaction, although felt a little bit jealous, but she can't deny that she loved this warm atmosphere.

Jin who noticed her gaze, looked toward her, and smiled.

"Medea, is there something wrong?"

"No, nothing, Master. The food is great." (Medea)

"As long as you like it."

Jin spoke with a smile.

A couple of minutes later, they all finished eating and put the empty plates in the sink.

"Ok, Sakura-chan go take a refreshing bath first, I'll massage you before you sleep."

Jin spoke as he headed towards his room to take a bath.

____/Scene Change\____

The young Primordial was currently relaxing in the bath while closing his eyes. Suddenly, he heard the sound of footsteps getting closer. He looked back to see Sakura who only got a bath towel around her body.

"What's wrong, Sakura-chan."

It wasn't the first time he saw her like this, they used to take baths together when they were younger. However, they stopped doing so for years, so seeing her like this today he was surprised that she became aggressive in her approach.

"I-I wanted t-to take a bath with N-Nii-sama like before."

Sakura whose face was burning from looking at his naked body spoke while stuttering.

"Sure thing, the bathtub is wide enough."

Jin spoke without a care and relaxed again. However, his eyes shot open when he felt the weight of another person and two soft things on his lap.

He looked at Sakura who was now in her birthday suit and spoke.

"The bathtub is wide enough for multiple people you know." (Jin)

"I know, but I want to stay like this." (Sakura)

Sakura spoke as she leaned her whole weight at him and closed her eyes.

Seeing her like this, Jin hugged her soft body as he put his chin on her neck. Feeling his hot breath on her neck, Sakura moaned.

"Ahn~ Nii-sama…" (Sakura)

Sakura then almost fainted from happiness when she felt something hard poking her from below.

"Nii-sama, your thing…"

"Well, what do you expect? I am not a eunuch, so of course I would get a reaction when an extremely beautiful lady is sitting naked on my lap and moaning in my ear." (Jin)

Jin stated it as a matter of fact as he kissed her neck, while Sakura kept letting muffled moans.

"Sakura-chan, you know that I already have a lover, right? Are you sure you want to do this?" (Jin)

Sakura who heard him looked at him and spoke with a serious tone.

"Saeko-san, right? I know, but I don't care. Nii-sama is my whole life, I don't want to be separated from you, Nii-sama.

You were always there for me and protected me, you gave me hope and a reason to live when I accepted my destiny.

I really hate the idea of sharing you with other women, but I hate the idea of not being with you at all even more!

I know it's wrong and selfish. You have saved my life and treated me as your treasured sister. You spoiled me so much as if I were a princess, but I am not a good girl! Why can't I be satisfied with that?! Why did I fall in love with you, Nii-sama?!"

Sakura's face was covered in tear as she was screaming the last part.

Hearing her, Jin felt like an asshole. He knew that Sakura always loved him, but he didn't take the final step with her and he didn't expect her to be affected deeply by this.

Jin didn't say anything and only pressed his lips against hers.

Sakura was taken by surprise at first, but she returned the kiss. She opened her mouth slightly and Jin took the chance to push his tongue inside. Sakura let a slightly muffled moan from the surprise, then she surrendered her body to him and let him do as he pleases.

After a couple of minutes, their lips separated and left a trail of saliva between them.

"Your Nii-sama is a total asshole, do you still want to be with him?" (Jin)

"Nii-sama is not an asshole! He is a womanizer, but he is a good person!" (Sakura)

Jin who heard her was dumbfounded.

'Did I just receive a 'Good Guy' card from her?!'

"Nii-sama, what's wrong?"

Seeing him frozen, Sakura spoke with worry.

"No, nothing. But know that I promised to take Saeko-chan's first, so I won't have sex with you right now." (Jin)

Just as Sakura was about to become sad, she felt his hands roaming around her body as he spoke.

"However, I can still 'play' with your body to my heart's content. Hehehe."

Jin spoke in her ear as he started letting his hands roam around her body.

He then started kissing Sakura again as one of his hand started massaging her breasts while the other went down to tease her honey pot.

Sakura's body was extremely hot from her Nii-sama's touch. She couldn't help but orgasm multiple times from the way her beloved Nii-sama was toying with her body. Every time he teased her nipples or pinched her clit sent shivers down her spine. She finally couldn't take it anymore after he slightly inserted one of his fingers inside her.

Sakura was currently lying on his chest while breathing heavily and she couldn't even move a muscle. It was her first time feeling this much pleasure. Even when she often fantasized about her Nii-sama, she couldn't feel this happiness she was feeling from his touch right now.

The young Primordial seeing her like this, he carried her in a princess carry after drying her, he used his powers to make her wear her clothes and lead her towards her room.

____/Scene Change\____

It was the next morning after Jin 'played' with Sakura in the bathroom. Jin was currently making breakfast for himself, Medea and Sakura who was still sleeping.

He was accompanied by his lovely servant in her pajama, who was currently taking notes while watching him cook. She was occasionally helping him in minor tasks like washing the vegetables or cutting them.

"Medea, what are you going to do today? Are you going to dematerialize and accompany me to school, or are you going somewhere else?"

Jin asked the diligent Medea who was staring at the potatoes in her hand like her natural enemy because she couldn't peel any of them.

Medea snapped back and replied.

"I was going to roam the city first, I want to check on the other servants and Masters first."

"Ok but be careful. If you met someone strong don't engage. If you were trapped or something, contact me to use my command spell to summon you."

"Ok, Master"

Medea felt warm inside her from the care she was receiving from him. He was the first person to treat her with genuine kindness without seeing her as a tool.

Seeing his smile, she reaffirmed her conviction that she will protect this smile even if it costed her life in exchange.

'I will win. I don't want to disappear after feeling this warmth for the first time.'

Her thoughts were cut when they heard Sakura's voice.

"Nii-sama, I'm sorry I overslept!"

"Haha, no problem. You were exhausted yesterday after all. Is your body ok now?"

Jin asked with a teasing smile and watched Sakura's face going red at an alarming rate when she remembered what they did yesterday in the bathroom and how her Nii-sama played with her body to his heart content.

"U-Un. I am ok…"

She replied with an extremely low voice.

Medea thought that she was acting strange, but she ignored it and continued to focus on taking her notes.

____/Scene Change\____

Right now, Jin and Sakura were walking towards the school grounds. Suddenly he felt someone sneaking on him and crouched.

[Swoosh sfx (rolled paper swung at great speed)]

"Taiga-chan-sensei, will you please grow up?"

Said Jin with a sigh as he got up and saw his 'attacker'.

"Good morning, Jin! As sharp as ever." Taiga)

"And you are as annoying as ever, it's early in the morning and you are trying to hit your student with no remorse. I'll sue you for using violence." (Jin)

"Don't mind the small stuff! And I told you, call me Fujimura-sensei not that stupid title!" (Taiga)

"Don't mind the small stuff, Taiga-chan-sensei!"

He replied with the same sentence making her speechless.

"Nii-sama, you are as shameless as ever…"

Sakura said with a sigh.

"Hey, she started it!"

Jin said as he looked 'innocently' at Sakura.

Sakura rolled her eyes at her antics. This has been their morning routine for some time now.

"Well then, see you later, Nii-sama, Fujimura-sensei."

As she said this, Sakura got closer and tiptoed and kissed Jin on his cheek, then ran away in embarrassment.

"OHHHHHH! So bold, Sakura-chan!"

Taiga squealed as she saw Sakura kissing Jin on the cheek.

It was good that there were no one paying attention to them or the school would've gone into an uproar. Although, it is known that Sakura and Jin are siblings, Jin was considered the prince of the school and he never showed public affection with a girl before, including Sakura. He is also known for his flirty nature, but they never find it repulsive as he is extremely handsome, and since he never takes it so far except making few teasing remarks.

Seeing this, Jin sighed as he smiled wryly at Sakura's action.

"So, Taiga-chan-sensei, where is Emiya?" (Jin)

"He got kidnapped by Ryuudou to fix some broken equipment." (Taiga)

"Again? The dude should learn to refuse from time to time, he is literally titled as 'Homurahara's brownie'." (Jin)

"I know right? I told him the same thing countless times, but he never listens because he can't refuse someone asking for help." (Taiga)

"Tell him not to push himself so much, if his body fell apart, he won't be able to help even if he needs to." (Jin)

"I'll tell him, see you at the club later." (Taiga)

Seeing this energetic teacher first thing in the morning is always a good way to cheer your day up.

____/Scene Change\____

Inside the archery field of Homurahara high school, Jin was surrounded by his fellow members and cute kouhais who were checking on his health.

"""Captain/Senpai, are you ok now?""" (Random Mob Crowd)

"I'm fine now, thanks for asking. Now, off to your practice."

Jin clapped his hands as the crowd dispersed to continue their practice.

He then ignored Shinji who looked like he was in a bad mood like always and went to change his clothes.

_____/Scene Change\____

Jin was currently wearing a Kyudogi (Practice Clothing), he has just finished shooting all his arrows. Which are all in the bullseye.

He heard the sounds of footsteps coming closer and looked back. He saw Sakura and his cute kouhai and vice-captain Mitsuzuri Ayako coming closer.

"Sakura-chan, Ayako-chan, finished already?"

He asked with a smile.

"Yes, Nii-sama."

"Yes, senpai. Good work here."

Ayako said as she handed him a water bottle.

"Oh, thank you, Ayako-chan."

Jin said with a smile as he took the water bottle from her and drank.

Ayako felt strange since normally Sakura would be fuming right now, but currently she was only looking at her brother with a smile. It was not a secret that she is a huge bro-con after all.

After spending some time flirting with his cute kouhai, he changed his clothes and left the club with Sakura and headed home.

____/Scene Change\____

Arriving home, he was met with Medea who was currently playing a cooking stimulation game with great interest.

Medea who noticed their arrival greeted them.

"Welcome home, Master, Sakura-san"

"We are home, Medea. So, how was your day?"

Jin asked with a smile as he sat on the couch near her.

"Quite good actually."

She was in a good mood while saying this.

"What happened?" (Jin)

"I killed a master before he summoned his servant."

Medea spoke with a smile as she continued playing her cooking stimulator, leaving Jin who was rubbing his head from headache and Sakura who chocked on the water that she was drinking.
