Hello everyone, it's me; Just shipping! I don't know how long it has been since I have uploaded a story, but this is a prompt I wrote one or two years ago. I wanted to upload this, but then I remembered that it was my sweet sis, RukiYuki's birthday. So I wanted to upload this for her as a gift. I know that I am a week late with it, but I still hope that you will like it.

I hope the others will like it too, please leave a review. I will update the previous chapter, but I am struggling with it as I am not good in writing action scenes.

Please enjoy this update!

Forbidden

Rule number one of the bro-code: Sisters are off limits!

Kurosaki Ichigo just knew that he was screwed. Really really screwed!

''Man, Ulquirra is really going to kill you'' his blue-haired friend told him while grinning.

Ichigo scoffed ''Jeez, thanks for the information. As if I did not know that!''

Grimmjow shrugged ''Hey, I did tell you who and what she was. You were the one who decided to...'' Frowning, he looked toughly at his orange-haired friend ''It is a real relationship, right? Not a hook up- thing?''

''Of course it is a real relationship! You know me better than that, you idiot!''

Grimmjow raised his hands up in surrender and shook his head ''Hey, I just had to check it. She is not only that emo's sister; I consider her as my own sister as well.''

''Don't tell me that you are also against this relationship. It's bad enough I will have to confess to Ulquirra and...'' but before Ichigo could finish his sentence, he was interrupted by the sound of his phone. And judging by the ringtone, he knew who it was.

''It's her, isn't it?'' Grimmjow asked.

Ichigo did not reply to him, but searched for his phone at the dinner table. Little did he know that his phone was at the coffee table, in front of his blue haired friend.''

''Oye Kuchiki, what's up?'' Ichigo's eyes got wide open when he realized his phone stopped ringing and it looked like Grimmjow had picked it up. Turning around to face him, he saw that Grimmjow had really picked up his phone and was grinning at him, while listening to whatever was being said from the other side. He ran towards him to grab his phone, but Grimmjow just ran away with his phone. Reaching the bathroom, he locked the door.

''OYE RUKIA, HANG UP! I WILL CALL YOU BACK LATER!'' Ichigo yelled while banging on the door, hoping that his voice would reach his phone. Five minutes later Ichigo heard the lock being unlocked and the door opened while Grimmjow was looking at him seriously.

''What did you say?'' Ichigo asked.

''Nothing much, I just told her that we had to meet with just the tree of us, so we could talk about this whole situation.''

Ichigo nodded ''When will that be?''

Grimmjow looked at the clock; ''That will be in two hours.''

Ichigo frowned ''Why so late? She has no appointments today and neither do I. As for you; you only go to classes when you want to and with Nel absent, I doubt you will go to class.''

Grimmjow nodded ''I told her that we will meet in two hours, because first I need to talk to you!'

Ichigo sighed ''Again! Did we just not talk enough?''

Grimmjow glared and Ichigo knew that he was serious. ''Fine, but let's go to my room, in case Ulquirra comes home and he hears us talking.''

Grimmjow agreed and both walked towards Ichigo's room.

''WHAT THE HELL WERE YOU THINKING, KUROSAKI? DATING ULQUIRRA'S LITTLE SISTER? YOU DO KNOW THAT THAT IS AGAINST THE BRO-CODE RIGHT? IT'S THE EIGHT RULE OF THE BRO-CODE! YOU NEVER GO AFTER A GIRL WHO'S RELATED TO YOUR BRO! THAT IS FORBIDDEN!''

Ichigo sighed for what looked like the hundred time of the day ''I know; do you think that I wanted this?! That we both wanted this?! We both tried to stay apart from each other, but that did not work well!''

Grimmjow frowned and thought loud by himself ''You mean those two months in which you were grumpier than before and if it was up to you, you would just stay in bed?''

Ichigo nodded and Grimmjow rubbed his cheek. ''I remember that, you punched me really hard that time, when I tried to get you outside. Wait, that was why you would give Ulquirra the evil eyes?! Because she is his sister!'' Ichigo confirmed this again by nodding and Grimmjow sat next to his friend.

''Look, I know you, Kurosaki and I know that you would not just hook up for fun. And I remember that more grumpy-time of you. Even after what I said about the bro-code, I will support you, because you and Kuchiki are not just two idiots who just jumped into a relationship.''

Ichigo looked up ''Really?''

Grimmjow nodded ''Yeah, plus what Kuchiki just told me about the two of you, made me convinced that this is the real deal.''

Ichigo smiled ''Thanks!''

''But please do not let me hear once again such a sappy lovey dovey conversation again! It really made me throw up!'' Grimmjow referred to the phone conversation he overheard, when he entered the apartment. Ichigo punched his friend in the arm and both laughed together.

''But do tell me, when and how did this happen?''

Flashback

Kurosaki Ichigo knew that he was screwed. But still, he could not stop kissing her. After a while they stopped kissing and searched for their breath.

''Wow'' the violet-eyed girl sighed. He could not help but nod.

''Why did you kiss me?'' she asked with her eyes wide open.

He sighed ''Isn't it obvious, Rukia? Why would I kiss you?''

She shrugged ''Maybe for a time pass, I don't know.''

He scoffed ''What do you think of me? That I am like that? I don't kiss random people, Rukia!''

''Really?''

''Yes, really. Plus, you are the sister of one of my best friends'' Realizing this, his eyes got wide open in shock. ''Shit, Ulquirra is really going to kill me.''

She nodded at this. ''Really? You are not going to cheer me up?''

''I am not going to tell you any lies, Ichigo.''

Ichigo sighed ''Look Rukia, I really like you since the moment I have seen you. I tried to ignore my feelings for you, because of my friendship with Ulquirra. But that was not easy, as I am drawn to you.''

''Is that why you suddenly started to ignore me?''

He sighed and rubbed his neck ''Yes, but seeing you here at the party, talking with Renji, it drove me crazy!''

She wrapped her arms in front of her chest and raised an eyebrow ''And that's why you dragged me outside.''

''I'm not proud of my behavior!''

''That's good'' she said while walking towards him ''Because know this; I'm not a toy that you can just do with whatever you want to do.''

''I know that too, I'm really sorry''

''But'' she said interrupting him while putting her hands around his shoulders '' for some reason I like you too and I also tried to forget about you, which did not work. Also, Renji is one of my closest friends, nothing more.''

He gave a small smile ''I'm glad to hear that you like me too.'' And he wrapped his hands around her waist, while leaning in to kiss her again.

End flashback...

''And that's how we ended up together.'' Ichigo said.

''But how do you go out together? I mean neither one of us had a suspicion, we all knew that Ulquirra asked you to help her with math, but I cannot imagine that that is the only time you two have dates.''

''Well, I still help her with math, but we also get together while claiming to meet our other friends. It's not easy to go around here on a date, but we would go to the nearby cities.''

''Impressive'' Grimmjow nodded and Ichigo just shrugged.

Two hours later the two friends were both sitting at the diner, while searching through the menu what to eat.

''I will take the double cheeseburger with extra fries'' Grimmjow told the waitress.

''And for me two chicken burgers, both with fries, one chocolate milkshake and one strawberry milkshake.''

Grimmjow raised his eyebrow ''Damn, or you are really whipped or you have a huge appetite.'' Finishing his sentence, he felt a punch on his head from behind.

''No, he's a real gentleman who knows what I would like to eat, you baka!'' came a familiar feminine voice from behind. Ichigo turned towards the voice and saw his secret girlfriend, Kuchiki Rukia.

''OUCH, WHAT WAS THAT FOR?'' Grimmjow yelled at her.

Rukia shrugged and sat next to her secret boyfriend, who was sitting at the opposite of Grimmjow. ''You are making a too huge of a deal of this, Grimmjow!''

''How am I making this a huge of a deal? You know your noble family and let's be honest, your father hates the Shiba's and the Kurosaki's. And your boyfriend being a product of both of them; THAT IS A HUGE DEAL!''

''Will you keep it down?!'' Ichigo angrily whispered at his friend. ''We both know that''

''And yet still the two of you decided to get in a relationship!''

''Nel was right, you would make a big deal of this.'' Rukia mumbled.

''She sure was... Wait what?! Nel knew this before me?!'' Seeing the couple nod, his eyes grew wider ''But she is my girlfriend, she should have told me.''

''No, because that is against the girl-code.'' Rukia told him.

Grimmjow looked at his friend ''You see, even my girlfriend follows the code and you could not follow the bro-code!''

''Would you knock it off already? I already told you how this started and I thought that you were now okay with this.''

''Well, if and really if you are going to tell Ulquirra, he will get to know that I knew it before and as much as I hate to admit it, his punches feel like hell.''

''Once again; you are making this too much of a big deal. Ichigo will tell nii-sama''

''When?''

''Tonight''

''Okay. Wait tonight?!'' Grimmjow did not expect that and seeing Rukia's reaction, he could tell that neither did she. Ichigo nodded.

''But Ichigo...''

Ichigo interrupted her before she could continue ''It's has taken a long time, Rukia. I really think that now is the time. And before you say anything, I think I should talk with him alone.''

''But...''

''But nothing, Rukia. It's better if he hears it only from me and I do not want him to insult you, so that's why I want to do this alone.''

''He's right, Kuchiki, it's better if he does this by himself.''

Rukia sighed ''I do not like this, but fine!''

Ichigo smiled and caressed her hair ''I know that you do not like this, but from this point on all your opinions are rejected!''

''What the hell is that?! You are ignoring all your girlfriend's opinions?!'' Rukia said

''What kind of tyrannical way is that to be someone's boyfriend?'' she whispered in anger.

''The one being my girlfriend doesn't get to complain as I will be facing her brother alone! You just act the part and stand around trembling and say my hero, you saved me!'' He said while trying to mimic a female voice during the last few words.

''My hero, you saved me! My butt!''

''Which is really nice''

Rukia couldn't believe her boyfriend and hit him with a fist. He yelled in pain and both started to bicker more. Grimmjow just looked at the couple and shook his head while finishing his meal.

The couple realized what they were doing and stopped their bickering while smiling. Ichigo gave her a kiss on her forehead and Rukia blushed at his.

''I mean it'' he whispered. ''It will be better if I will tell him about us by my own.''

She sighed ''I know, but that does not mean that I like it.''

Both looked in surprise when the heard Grimmjow sigh heavily ''I did not expect you two to act so so ugh...! I mean; Come on, you two, I am trying to eat.''

''What is stopping you then?'' Ichigo asked.

''You two acting like that. But, I have to admit; you two really make a perfect pair. You both can handle each other, so Ichigo, you can tell Ulquirra that too while trying to convince him.'' he handed Ichigo some money ''This is for my meal, I will head out now as I am sleepy now. You two enjoy and Kurosaki, good luck today!''

Ichigo nodded in thanks and Grimmjow walked out.

''So what do you want to do now?'' Rukia asked when both finished their meals.

''Do you want to take a walk with me in the park?''Rukia nodded and both stood up.

Ichigo saw that no one was at the park, except for parents with their children. He took his girlfriend's hand and intertwined their fingers together. She smiled and squeezed his hand.

''Remember when we both had to go at that noble ball and could not really talk with each other?''

Rukia nodded ''Yes, you only greeted me and then started to talk with my brother.''

Flashback

As every year there was a ball only held for the nobles and the people that they would invite to it. Rukia never really liked these balls, but this year she would do some more effort as her boyfriend would there be too. Not that she would get to dance with him, with everyone around them. As they were only dating now for a month, but did not think that it was safe to tell anyone. And first her brother had to know about it, before the rest of her family would get to know about it. After all, her father disliked the Shiba's and Kurosaki's and as her boyfriend was both of them...

''Damn, this is really forbidden.'' She thought while looking at her hair.

She was wearing a long black dress with sequins on top and from the waist it was made with silver tulle and a black layer underneath it. The dress had spaghetti tops and Rukia was also wearing silver heels.

He better not make any jokes about my height, she thought by herself.

She had just put her hair in a high bun and had smoky eyes with red lipstick.

Hearing her phone buzz, she grabbed it and saw that she just had received a text message.

Opening it, she read that her boyfriend was asking her for a photo of her outfit.

Not a chance! You will have to wait for me to make an appearance. She replied.

Come on, Rukia. It's already a big thing I am willing to go, as I never go to this ball. He replied back.

Have some patience, Ichigo. I did not force you to go to this ball. Plus you already know the colors that I will be wearing. She replied back.

Fine, I will wait. But hurry up!

She had just replied to his message, saying that she would and heard a knock on her door.

''Rukia, are you ready?'' her brother asked from outside.

Rukia put her cell phone into her clutch and walked to open the door.

''I'm ready, nii-sama.'' She said while opening the door.

At the ball

Rukia walked with her family and looked around to see who was already there. A lot of families were already there.

''Ah, the Kuchiki's are finally here.'' Rukia looked up towards the source of the voice and saw Shihouin Yoruichi and Urahara Kisuke. She smiled and greeted them. She could see from the corner of her eyes that her mother was urging her father to greet the couple, which he did with a lot of self-control.

''Ah Byakuya-boo, it's been a long time since I have seen you. Your kids are really grown up now.''

Rukia got distracted as she felt her cell phone buzz in her clutch. Opening it, she took her phone and read the text message, that she just had arrived.

Took you long enough. Her boyfriend messaged her.

Where are you? It's impolite not to greet. She messaged back.

I'm coming, I'm coming. The old man is lecturing Karin and me to greet everyone.

''It seems like you are having an important talk at your phone'' Rukia heard Yoruichi whisper to her. Looking up, she saw her looking at her and in shock she looked around if her father or her brother did not see it. They would lecture her about being appropriate and all.

''Don't worry, they did not notice anything as they were greeting Ukitake. But you better go to them, or else they will notice'' Yoruichi told her with a wink and Rukia smiled in gratitude.

''Thank you, Yoruichi-san.'' She said and walked towards her family.

Just as she greeted Ukitake, she heard Ichigo's father.

''Ah, the Kuchiki clan came. Hisana, every time I meet you, you look more and more beautiful. Your daughter truly gets her beauty from you.'' Shiba Isshin said to Rukia's mother, who smiled at the compliment.

''And you are still as charming as ever, Isshin-san.''

Isshin looked at Rukia and smiled ''Ahw, Rukia-chan, it's always nice to meet you. And it seems like you matched with my son, he's wearing grey and black, right Yuzu?''

Yuzu who just hugged Rukia as she greeted her nodded ''Yes, onii-chan and Rukia nee-san are really wearing matching outfits.''

Byakuya who was getting annoyed by this comment answered coldly to Isshin ''Indeed, what a coincidence.'' And he walked away to greet the other nobles.

Rukia and Ichigo just greeted each other and Ulquirra dragged Ichigo with him to catch up with him. Rukia sat down and started conversations with girls from her age.

After a hour she got a text message.

You look beautiful, by the way. Ichigo had texted her.

I know and I have to say, you look dashing as well, she texted back.

Could you do me a favor? He asked.

What do you want, Ichigo?

Could you come upstairs in fifteen minutes?

Why?

Just trust me.

Just as he had send his text message, he saw a shadow over him.

''I have to admit, I did not expect you to have the guts to do this.'' Shihouin Yoruichi told him as she sat down next to him.

''What are you talking about?'' he asked her.

She raised an eyebrow '''It really is a coincidence that you and Byakuya's daughter matched your outfits or that you even came here, I don't know how long it has been since you have been here.''

He looked in front of him towards the dancing people ''I still don't know what you are talking about'' he said.

''Sure and I'm a talking cat. But just know, I approve her.'' she said while walking away.

Ichigo just smiled and walked towards the elevator.

Reaching upstairs he saw his girlfriend waiting for him.

''So, why did you want to meet here? You know that it's not safe, right?'' she said walking up to him.

''Relax, I have it all under control. The old man thinks I had to get something for Karin and your family thinks that you took her outside to catch up.''

''So, you have your sisters lying for us.''

''Correction, sister. Karin had a suspicion that something was going on and she told me that if I needed to, she would cover for us.''

''I have the feeling you have to do something in return for her.''

''Yes, take her to the final match of her favorite soccer team and getting her out of attending this ball next year.''

Rukia wrapped her arms in front of her chest and nodded impressed ''I have to say, she knows how to make a good deal.''

Ichigo shrugged ''She's a smart girl, of course, what else would you expect of the little sister of Kurosaki Ichigo?''

''Your ego is getting too big, Ichigo. Now tell me, why did you call me here?''

Ichigo kissed her and Rukia could not help it, but kiss him back. After a while, he broke the kiss and leaned his forehead on hers.

''First; I wanted to do this and second; I thought it was a shame that we cannot dance together.''

Rukia pouted while she looked at the ground ''Well, we can dance together another time, just not now.''

He smiled and pulled away while taking her hand. ''Yes, we can.'' He said while walking backwards. When he stopped walking, Rukia frowned. ''What do you mean?''

He took his cell phone out of his pocket and put it on the ground, after he played some music on it.

''We can dance here.'' Walking to her, he offered her his hand. ''Can I have this dance, milady?''

Rukia could not help it, but laugh while she put her hand in his ''Yes, you can, sir.''

Together the couple started to dance.

End flashback

''That's one of the reasons why I want to tell your brother. After Ulquirra, your father will find out, but then we do not have to do everything secretly anymore.''

''I understand, Ichigo. But I know that my brother will not easily accept this.''

Ichigo sighed ''You trust me, right?''

Rukia sat up and looked at him ''Of course, I do! What kind of silly question is that?''

Ichigo smiled ''Then trust me when I say that everything will be alright.''

Rukia sighed but nodded ''Fine!''

Ichigo looked at his watch. ''It's getting late now. Let me drop you at your dorm room first and afterwards will I meet with your brother.''

Rukia nodded and the couple stood up to leave the park.

After dropping Rukia at her dorm room, Ichigo stood in front of his apartment and took a deep breath. Opening the door, he walked inside. Grimmjow quickly walked up the hallway to raise his tumbs to Ichigo and Ichigo continued to walk towards the living room. Seeing Ulquirra, he coughed a bit to get his attention.

Ulquirra turned towards him and Ichigo rubbed his neck.

''Can we talk?'' he asked him.

Ulquirra nodded and Ichigo continued. ''Well, it's about your sister and me. We...''

I know I am bad for ending this oneshot here, but I did not know what to do with the conversation. The only thing I know is that Ulquirra will hit his friend hard. I will try to continue the previous chapter, but I hope you guys liked this oneshot.
