A/N: Hey everyone! So this is my first attempt to a multi-chapter story and I really hope you will enjoy it. A CO-WRITER for this fic would be hugely appreciated since I'm not sure if I can do it all on my own and the help of someone experienced (or not :P) would be amazing. I know Robb/Arya's not a pairing people like but please, give it a try. Reviews highly appreciated, thanks.

Summary: After their break up, Robb didn't think he could find anyone that could make him feel the way Jeyne did. They were supposed to get married. It was their wedding day but she never came. From then on, Robb stopped believing in relationships and only cared for one night stands. However, living in the house with only his fifteen year old sister, Arya, could be problematic when he wanted some privacy. Ever since he entered the bathroom and saw her naked in the shower, he couldn't remove this image from his mind.

"Arya?" Robb called out his sister's name as he shut the front door behind him.

Not getting any response from her, he assumed she was not home and made his way upstairs. After a long day at work, the only thing Robb was aspiring to was a warm shower. Robb loved his job. After all, he had always wanted to have his own company, he knew how hard he had to work to succeed and he eventually got what he wanted the most. Even though Wolf's Den was a fairly new company, the results were there. The mark was present in several stores and he did see the growling wolf worn by more people every day.

His success, he owed it to his father. Without his help, he never would have made it. To his dismay, Ned Stark wasn't here to celebrate his son's success. Ned and Robb's mother, Catelyn both died in a car accident as they were picking Rickon up from school. Rickon Stark, another loss added to their family when the truck hit their car and killed Rickon instantly. Instead of sticking together, the Stark children drifted apart. The pain was too unbearable and the house only brought back memories that hurt more than anything. Sansa was the first to leave to go to college. Then, it was Bran who preferred to leave the house and live with his uncle Benjen. Jon stayed with Robb and Arya a few months before he moved with Ygritte, his fiancée, to their apartment. That left Robb and Arya alone. After the accident, Arya completely changed. Robb didn't know how to deal with her but assumed he had to let her deal with her pain in her own way. All the problems she caused in high school, her rebellious behavior and that new attitude, he blamed it all on grief but it didn't make anything easier.

Going to his room first, he quickly undid his tie and threw it on the bed. Wearing a suit everyday wasn't what he liked the most but when he had important appointments with investors or clients, he couldn't simply wear a pair of jeans and a shirt like usual. The rest of his clothes and shoes came off before Robb left his room and headed to the bathroom. Stepping inside, he automatically reached his boxers and was about to take them off when he abruptly stopped. Something was off. If he was alone in the house, then why was the water running?

When Robb looked up, he couldn't believe his own eyes. Water was running down her lean body, drops following the curves of her breasts before disappearing down her belly. He looked up to see Arya's face but she didn't seem to have heard him since she had her eyes closed. What the fuck? Since when did that happen? When did she grow up? And damn, how could he miss it? His sister wasn't a little girl anymore and that was beyond awkward. "Oh shit…" He groaned as he felt his manhood stir in his boxers.

A pair of grey eyes quickly opened and widened when she realized what was going on.

"Get out!" She yelled as she pulled the curtain to cover her naked body.

"Oh my god…Sorry, I didn't know…Sorry…" Those were the only words Robb could say before getting out of the bathroom as fast as he could.

Cursing himself, Robb headed back to his room only to get dressed again. The last thing he wanted was to face his sister after what just happened. Thinking about it, he couldn't help blushing. It was probably one of the most embarrassing moments of his life and he just needed time to think to figure out how to handle it. So after he got dressed, Robb grabbed his keys and left the house.

When Arya finished her shower, she went to her room and dried herself off. Opening her closet, she tried to find the perfect outfit for her date but what she owned was only the clothes of a fifteen year –old-girl. Sighing heavily, she then remembered a dress Sansa left her in case she decided to act like a real girl, Sansa's words, not hers.

"Perfect…" She muttered to herself as she found the black dress.

Laying it on the bed, she had to find Robb first. When he entered the bathroom, she was pissed. Pissed because she didn't lock the door and he got to see her, all of her. But when she thought about it, he felt probably ten times worse than she did. So he saw her naked. So what? It was an accident and she was sure they would forget it ever happened. After putting on something decent, Arya made her way to Robb's room.

"Robb? Can I come in?"

Not getting any answer, Arya opened the door, only to find it empty. Typical Robb, she thought. Sometimes, she even wondered when he would abandon her too. After all, they all left. Even though they all suffered from the loss of their parents and brother, they fled cowardly. She was angry. They were supposed to be siblings, to stick together no matter what. Especially after the tragedy. Yet, they left and barely called or wrote. How could they do this? How could they give up on their family that easily? Arya didn't understand and wouldn't forgive them for that.

With Robb out of the house, that meant she could get ready for her date and leave without actually sneaking out. About an hour later, Arya stood before the mirror and stared at her reflection. She couldn't believe it was really her. Sansa's dress stopped mid-thigh and hugged her curves perfectly. She had filled out and looked pretty, if she dared say so herself. A light touch of make up to make her look older and black heels would be enough. Finally ready, Arya grabbed the purse she bought earlier that week and waited for the taxi she called.

Getting out of the car after she paid the driver, Arya began to be a little nervous. She had told Jaqen she would meet him instead of having him pick her up and risking getting caught by Robb. Once she was inside the club, Arya scanned the crowd dancing. Valar Morghulis was the new club of the moment apparently.

"Good evening, lovely girl." A familiar voice whispered in her ear.

Arya swallowed hard, already knowing who it was. Turning around, she couldn't suppress the smile that was already forming on her lips.

"Hello, Jaqen. I hope I'm not too late."

"Nonsense. You look amazing, Arya." Jaqen said looking her up and down.

"Thank you. And you clean up well, Mr H'ghar." She answered, checking him out as well.

She had met Jaqen H'ghar only a few weeks ago in a coffee shop and couldn't take him off her mind ever since. In order to have a chance with the man, she had to lie and said she was eighteen and lived in an apartment with a roommate. There was no way a man like Jaqen would want to go on a date with her otherwise. He was teaching literature at university and was divorced. That was all Arya knew of the man so far and that was more than enough to her.

"Come on, let me get you a drink."

Arya simply nodded as Jaqen led them to the bar, his hand on the small of her back.

"What would you like?" The teacher asked as they both sat on stools.

"A mojito, please."

After Jaqen ordered the drinks, he turned towards Arya.

"So you told me you were in college…"

Without getting a chance to finish his sentence, the brunette interrupted him.

"Are we really having this conversation right now? I think you and I could find a better topic…like how much you want to kiss me right now." She said boldly, bringing her glass to her lips and took a sip.

Instead of saying anything, Jaqen chuckled and looked at her in a way she couldn't quite figure out but she liked it.

"You're definitely something else, aren't you? Who are you?" He asked in a playful tone Arya immediately recognized.

"That's a secret I'll never tell." She winked at Jaqen before getting off the stool and headed to the dance floor. She didn't have to turn around to know that Jaqen was following her.

Little did she know that her nice little night would end abruptly and sooner than expected.

As soon as Robb arrived to the club, he headed to the bar with a couple of friends for a much needed glass of whisky. As much as he wanted to forget what he had seen, he couldn't. And that alone managed to enrage him. He should have knocked…oh fuck that, it was all her fault. Why didn't she lock the door in the first place? It wasn't like she was living in the house alone. But his sister wasn't the one he was really pissed at. What he saw in that bathroom was a growing and curvy girl. He couldn't even remember when the last time he spent some quality time with Arya was. He remembered a little girl, not the girl in the shower. So yes, Robb was mad he didn't see his little sister grow up and pretty much neglected her. That wasn't the worst part though. The worst part was when he actually reacted to seeing her naked. His body responded to the beautiful sight he had in front of him and as much as he wanted to stop it, he couldn't. And he hated himself for it. He remembered how his cock hardened when his eyes moved up her legs or how he felt incredibly tight in his boxers and uncomfortable when his eyes set on her breasts. A wave of shame invaded him.

He was drinking his third glass when he decided to get rid of all those nasty thoughts and focused on his friends and the pretty girls there was at the club tonight. It wasn't long before a few girls came to them. Robb knew he was attractive and liked to play with it. He didn't even bother hitting on the girls most of the time since they were coming to him first. And every time it was ending the same way.

"Hey handsome…" A busty blonde whispered in his ear.

Robb looked her up and down, enjoying the view. He was more into brunettes but who was he to reject such a willing creature?

"Hey beautiful." He answered and got up before grabbing the girl's hand and leading her to the dance floor.

Robb wasn't a really good dancer but the girl didn't complain as long as his hips were moving against her back. His right hand holding her hips, he leaned forward, his groin slowly rubbing the small of her back. Noticing how responsive the girl was, he smirked. Nothing better than a good fuck to forget you had a shitty day. He made sure to pick the right girls, no strings attached and that was how it was. He never gave his phone number or cared to take the girl's when she offered it.

Turning around, the blonde whispered in his ear.

"Do you have a car?"

At those words, Robb smirked and grabbed her hand to lead them out of the crowded place. They were making their way through the crowd when he saw her. If it wasn't for her big grey eyes, he probably wouldn't have recognized her, at least not dressed like that.

Instantly, he stopped, which caused the blonde to stop as well and ask him what was going on. Instead of answering, Robb clenched his jaw at the show displayed before him. Arya was here. She was in the damn club, somewhat dancing with a man twice her age. What the hell?

Robb made his way towards his sister, angrier by the second. Reaching for her arm, he pulled her away from the man who clearly was older than she was.

"Bloody hell! What…" As Arya turned around to smack whoever had grabbed her, all color left her face. The last person she expected to see was standing before her, clearly pissed off.

"Robb…"

Before Arya could say anything, Jaqen stepped forward, obviously confused.

"What's going on here? Arya?"

"Arya's leaving and you're not going to see her again. That's what's going on." Robb answered instead, glaring at Jaqen.

"I…it's okay, he's my brother…" Arya didn't have the time to come up with a good excuse or lie to tell Jaqen as her brother dragged her out.

"What's wrong with you? Let go of my arm, you're hurting me." She complained and managed to free her arm from his grip.

Robb didn't say a word as he led them to his car and went for the driver's seat. Arya refused to move.

"Get in the car." He said in an icy tone.

Arya eventually got in the car, slamming the door shut. Now, she was angry too. How could he have humiliated her this way? She thought of Jaqen's confused appearance, wondering if she would see him again.

The ride home was silent but none of them minded. It was only when they arrived to the house that they let their anger out.

"What were you thinking? Is that what you do when I'm not home, huh? You sneak out and go out with perfect strangers? Look at you…This dress…" He shook his head as he tried to remain calm.

"What I do or who I see is none of your business, Robb. You humiliated me!" She snapped, trying to get it over with. She would not stand there and listen to him. Not tonight.

"When I see my little sister grinding some older guy at some club, I make it my business. I don't want you to see that guy anymore." His voice was deep and his tone was firm. He meant every word he said and she knew it.

"So it's alright for you to hook up with one girl every week but I can't simply go out and have some fun? You're such a hypocrite…I start to understand why Jeyne never showed up at the wedding." She knew it was a low blow but still made her way to the stairs, clearly wanting this conversation to end.

"This is not about me. You're fifteen!" He finally lashed out, unable to get his anger under control anymore.

"You're fucking fifteen, Arya! He looked like he was twice your age. Have you seen him before? Does he know you're underage?" He couldn't believe he had this conversation with Arya. Not her. The only thing he could do was prey she didn't do anything out of line with the guy or he knew he would do something he would probably regret afterwards.

Arya stopped at the top of the stairs and turned around. Looking down at him, he seemed so upset and at the same time lost that her anger somewhat softened.

"Exactly! I'm fifteen, Robb, not ten. I'm not a little girl anymore. I thought you would have understood that after you saw me naked this morning."

At the mention of the incident, Robb slightly blushed, suddenly feeling embarrassed all over again. But what she said was true. Arya Stark wasn't the little girl who was running around constantly, annoying Sansa or playing fighting with Bran. Never taking his eyes off of his sister, he went upstairs and stood right in front of her.

"I'm sorry about this morning. I didn't know you were there. As for you not being a little girl anymore…obviously you aren't and I have to accept it." He admitted, using the same comforting soft tone she was used to hearing.

"But you're fifteen. You're still underage…" He added, tentatively.

"Nothing happened between Jaqen and I if that's what you're wondering."

Saying he was relieved was an understatement. Robb slightly nodded and did something he hadn't done for a long time. Bringing her body to him, he wrapped his arms around her and hugged her tenderly. Arya's arms immediately went around his waist and hugged him back, loving the comfort she found in his arms.

"I didn't mean what I said. Jeyne was a fool for leaving you." She muttered, holding him even closer.
