So, I don't even know how to start. Once upon a time, I was happily browsing through Robb/OC fics and then I stumbled upon a Robb/Sansa one and it wrecked my life haha I decided to write a Robbsa fic of my own because I'm not kinda obsessed with this pairing. But unlike most stories I've read so far, Robb and Sansa don't start off as the closest of siblings in my story.

Anyway, give it a shot and let me know! I already have some more chapters written out.

PS: Incest is wrong, I know. But this is fiction, so whatever floats your boat :)

Sansa was sleeping peacefully, the overindulgence in alcohol from the night before making her sleep even more deeply. She had warned Joffrey that it was a school night but he had driven them to Seattle any way for a concert. It had been past three in the morning when she finally got home, carrying her heels in her hands with her hair in a messy bun, feeling like death.

The only reason she woke up at seven was because she felt a presence in her room. Slowly opening her eyes, she found Arya rummaging through her bedroom, under her bed to be more precise, where she kept her old textbooks and school binders from previous years.

Without missing a beat, Sansa waited until Arya was close enough and then grabbed a fistful of her younger sister's hair before dragging her through the hallway and down the stairs. She was done with her sister snooping around her stuff.

"Mom!" Sansa shouted angrily, once downstairs while Arya tried freeing herself from Sansa's hold without success. "Arya was going through my stuff again!" She complained once in the kitchen but Catelyn was nowhere to be found.

Instead, her oldest brother, Robb, was standing in front of the counter, next to fridge, preparing what appeared to be peanut butter sandwiches. Sansa wouldn't have found it odd if it weren't for the fact that he hated peanut butter vehemently. "Where's mom?" She asked him, finally setting Arya free as she headed to the fridge to get some orange juice.

"She left last night to go visit dad in San Diego," Robb sighed as he packed the tower of sandwiches inside brown paper bags. Sansa noticed his black t-shirt seemed a little tight around his biceps and torso. Maybe he'd have more time to go shopping if he weren't always busy playing the perfect son, Sansa snorted. Maybe then he'd also have some time to go to a hairdresser and finally have his curls cut. No one wore their curly hair like that anymore.

"I didn't know," Sansa admitted, sipping on the juice before noticing with barely hidden disgust that it had some pulp in it. "I wasn't here last night."

"I know, I heard you come in. You weren't exactly discreet." Robb sighed again as he gave his wristwatch a quick look. They were running late, and they still needed to drop Rickon off at school and then get Arya and Bran to theirs. Finally he lifted his gaze to look at his sister and noticed she was still in her flimsy shorts and sports bra she wore to bed. Sansa thought his gaze lingered a little too long on her chest area, but she quickly decided she was imagining it. "Just go get dressed Sansa, we need to leave soon."

Sansa laughed at him through her half full glass before setting it down on the counter, not bothering to put it in the dishwasher. "I have a free period this morning," she informed him as she grabbed an apple from the fruit bowl on the table and proceeded to bite into it. "So do you, if I'm not mistaken." She added, tilting her head to the side as she tried to remember the past school weeks. Yes, Robb had a free period too. He always drove her to school on Fridays.

"We need to drop off the kids at school first," Robb explained, looking somewhat annoyed when he noticed she had left her glass on the counter. Silently, he grabbed it and proceeded to pour the juice in the sink because placing in the dishwasher. He might have been silent, but Sansa could see he was becoming annoyed. He tended to clench his jaw in those moments which made his cheekbones look even more protruding. "Please Sansa, just go get dressed," he said as he avoided looking at her.

"You can drop them off, I'll drive myself to school," Sansa decided. She still needed to shower. Besides, what was the point of having her driver's license if not to drive?

"Mom's car is still being repaired, remember?" He groaned, finally turning to look at her and she knew he was pissed. That in itself wasn't surprising. She was always pissing him off, and he always managed to get her all riled up, the only particularity this time was that it wasn't even eight in the morning. "We leave in twenty minutes," he decided, leaving her alone in the kitchen as he made his way to his bedroom above the garage.

Sansa ran upstairs fast and locked herself in the bathroom before Arya could race her to it. She never showered that quickly in her life, even foregoing to properly care for her long, copper hair. Instead, she only tumble dried it before tying it in a messy ponytail. Sansa threw her makeup inside her bag and rushed downstairs only to find the house empty.

If Robb had left without her she'd- Sansa almost starting shouting before she opened the front door and noticed everybody was already in the car on the driveway.

As soon as she set foot inside the car, Robb drove off. Bran immediately started complaining that she would make them all late but Sansa merely addressed him the middle finger through the rearview mirror. Robb swatted her hand away but she heard Arya sniggering in the backseat. The only thing the sisters had in common was their lack of patience for Bran's scholastic ways. At least they had saved her the passenger seat, though she was quite sure that was more due to the fact they knew she would get sick in the back than real kindness.

Sansa tried applying her make-up using the small mirror in the visor as Robb parked the car in Rickon's school's parking lot. That was still pretty close to home, but Arya and Bran's junior high was much further away.

"Rickon put on his t-shirt the wrong way but I didn't want to say anything," Arya commented as Sansa eyed Robb crossing the road with Rickon until they were at the school's front door. He was always like that, the perfect brother, Sansa thought sarcastically. She was pretty sure that if she were to ask her brothers and sister who their favorite sibling was, they'd all say Robb. Hell Robb had always been mom's favorite child too until Rickon came along and stole all the attention.

Sansa turned her attention back to the mirror on the visor when Robb started heading back to them. Out of the corner of her eye, she noticed Arya was copying off her homework on her lap. So that was what she had been doing in her bedroom, Sansa concluded with a smirk. For a moment, she wanted to say something but then decided against it. Everyone was already on edge as it was.

Robb slammed on the gas pedal to get Arya and Bran to school in time but even so, the first bell had already rung when he came to a screeching halt in front of the building. "I put the snacks in your backpacks he announced," turned on his seat to stare at his siblings in the back. "You'll take the bus back home right after school. No wandering around!" He said authoritatively and Sansa had to look out of the window with a smirk. She'd slap him if he ever talked to her like that.

Silently, Bran and Arya stepped out of the SUV and Robb stayed parked, making sure they both entered the school's building before driving off. She really doubted Joffrey would be like that with his younger siblings, waking up early only to drive them to school but then again Cersei was a stay-at-home mom and they had drivers in any case. Sansa loved going to their place – they had an indoor pool and she enjoyed swimming in it. Besides, the servants would always bring her some freshly cut fruit afterwards. Joffrey's father was never home and Cersei spent all her time with her brother Jaime, which meant they were always free to do whatever they wanted.

Robb slowly pulled into the local café franchise drive-through lane and Sansa addressed him a questioning look. He disliked that place, something about their unethical plastic straws and how they didn't even serve real coffee to begin with. "I know you didn't have breakfast before we left," he simply explained, surprising Sansa as he correctly ordered her favorite drink and a macadamia nut muffin

Sansa started digging inside her handbag to hand him the money but he paid before she had found her wallet and then refused to take any of it. Father would throw a fit if he found out she had been eating in his car but she doubted Robb would be snitch on her. He had never been a snitch and besides, it was his idea.

The drive to high school was silent. Sting's Desert rose was playing on the radio, not too loud and Robb always liked to listen to that kind of music. It wasn't exactly her cup of tea but she was too busy texting Joffrey to even care.

Joffrey: Lakehouse this weekend.

Sansa: Pick me up at five?

Joffrey: Yes. Bring a bikini.

It was always like that between the two of them. They weren't dating, there were no boyfriend or girlfriend labels, and Joffrey most likely slept his way through high school but it when it came down to it, it was her he brought as his plus-one to his uncle's wedding and who he had taken skiing in Aspen with his family. He was a little cold sometimes – mean or nasty was more accurate – but Sansa put up with it because those moments where he wasn't made up for it.

Robb was already parking the SUV when Sansa finally focused on her surroundings. The parking lot was mostly deserted; either you were in class or you used your free period to sleep in. It was what any sane person would do. It was what she would have done.

He was sitting in silence next her, wearing his aviator Ray-Bans and typing away on his phone. It was always like that between them. If she were Arya or Bran, Robb would surely be talking and making jokes, but with her there was mostly silence as she ate her muffin, trying not to make too many crumbs.

"Your friends are here," Sansa announced sarcastically as she noticed a grey Jeep driving past them, Jon and Sam sitting in it. She never understood how Robb could be friends with them. Theon, well he was popular and in the football team, but Jon and Sam? The first one was always brooding as if in deep anguish and the latter, he would babble on about English literature all day if he could. "I don't even know how you can be friends with these people."

"Says the one who hangs out with Joffrey and the likes," Robb gnarled, his icy tone surprising her. Usually, she was the mean one, not the other way around.

"What the fuck do you mean, 'Joffey and the likes'?" Sansa retorted, now turning around on her seat so she could look at him, but he was purposefully avoiding paying her the same attention.

"Tongue, Sansa," he hissed, sounding just like their father. "You think you're one of them now, but he'll grow tired of you and then you'll lock yourself in your room, and it will be up to us to pick up the pieces." Robb had always disliked Joffrey, perhaps hated was the correct term but when Sansa began dating him, it became so much worse. According to Robb, that blond boy was a prick and he didn't want his sister's heart to be broken.

"As far as I remember, you're the one who got your heart broken just what, a month ago?" She immediately replied.Talisa. Sansa had never liked the girl. Arriving in Winterfell only three years ago and trying to enchant everyone with her foreign looks and accent. "Besides, Joffrey and I, it's not like that. Which reminds me – he will pick me up at five and we'll spend the weekend at the Lake House."

Sansa was looking forward to it. Margaery and her brother, Loras, would be there. Myrcella would be coming too, obviously, and other people she didn't know so well. It would be fun and Joffrey and her would get some alone time on his motorboat. "You're not going, Sansa," Robb said calmly, finally turning to look at her. "It's Sam's birthday today and I promised him a long time ago I'd make it. Someone needs to stay with Arya, Bran and Rickon."

"Does he even have enough friends to throw a birthday party?" Sansa joked but the look on Robb's face let her know he wasn't impressed by her humor. "Do you really trust me to be the responsible adult?" She asked, wondering about it herself. She could barely take care of herself on most weekends, always waking up the next day with an hangover.

"It's just tonight, please, Sansa," he said but his tone was far from pleading, sounding more like annoyance. "You can go to the lake house tomorrow morning for all I care."

Sansa wanted to protest but then both backdoors opened at the same time as Jon and Sam joined them, effectively cutting off their argument. Jon nodded to her as a way of greeting, but Sam couldn't stop himself from letting out a girly 'hi' in a high pitched voice. "If you want to join us tonight, that would be-" He suggested, tumbling on his words and Sansa rolled her eyes behind her sunglasses.

"No way in hell, Sam!" Sansa replied coldly before opening the passenger door and bolting out, hurrying inside the building, still too early for her first class but she was angry at Robb and there was nothing she could do about it. If she called mom, Catelyn would side with him in an instant.

Joffrey was disappointed when she told him she wouldn't make it tonight and even suggested she leave without telling Robb. The idea was tempting but even she wasn't irresponsible enough to do it. Arya would use the occasion to go out with friends God knows where, Bran would try some weird chemistry experiment in the kitchen and burn the whole down. Rickon, she didn't even dare imagine, maybe eats slugs in the garden.

The day dragged on and on but finally classes ended at three, and Joffrey drove her home in his brand new red Jaguar. Sansa noticed the way all the girls stared at them as they walked to his car, side by side with his arm around her shoulders and their envy fueled her energy. Maybe Joffrey was a prick from time to time, but she was his princess and it was her that he drove home.

"I don't know how you can be a Stark," Joffrey commented, implying his well-known dislike for her family, driving one-handedly with the car top down. Sansa found herself ogling him, somehow realizing how skinny he was for the first time. His arms were probably as thin as hers and his jaw was somewhat lacking, she noticed. And then she realized whom she was comparing him to and almost choked on the air she was breathing before shaking those thoughts.

"Neither do I. My whole family sucks," Sansa replied and felt guilty as soon as the words left her mouth. Maybe the Starks weren't as perfect as the Baratheon, but she loved her family all the same, even Robb. Perhaps especially him. Her feelings about her older brother had always been conflicted. Next to her, Joffrey chuckled at her words as he pulled in on her driveway.

"You're joining us tomorrow then?" He asked, rhythmically tapping his fingers on the steering wheel as she gathered her stuff.

"Yes, I'll leave in the morning," Sansa promised, leaning over to kiss him. He tasted of the coke he had been drinking just a few minutes ago and she couldn't help find the sweet, sugary taste of it somewhat sickening. He was pulling her closer to him, his hands roaming over the sides of her breasts and she almost tipped over the center console and on top him but Joffrey didn't seem to care, his hands become more ravenous. "Everyone can see us," she whispered out-of-breath when his intentions became clear to her.

"You could always let me into your house," Joffrey suggested and Sansa grew uneasy. She had been to his house a thousand times, but he had never set foot inside hers. It wasn't only that she felt somewhat embarrassed by her more modest house, but she didn't know what Robb would do if he got home to find the two of them fooling around. For some reason, she imagined his reaction would be just as a bad as mother's.

"Another time, my siblings will be home soon," she said, pecking his cheek before pulling herself away from him and leaping out of the car. Joffrey drove off as soon as she had crossed the road.

That wasn't nearly as bad as she had expected, Sansa was forced to admit. 'Breakfast for dinner' had been Rickon's idea and it had actually turned out quite nicely. Only one plate had been broken and no one suffered grave burns as they sat around the table to eat pancakes, bacon and cereal. Arya hadn't even been a pain in the ass which was a first.

"Your pancakes are actually better than mom's or Robb's," Bran muttered with a full mouth, and Sansa noticed her other two siblings nodding in agreement. The compliment surprised her and warmed her heart just as much. Maybe staying in on weekends from time to time wouldn't be so bad.

Bran stayed with her to help her clean-up after they had eaten before going upstairs to play a game called 'Minecraft' or something like that. Arya had already gone to her room, texting and calling her friends. Sansa set the fruit bowl back down on the table and sighed with a small smile. Spending time with them wasn't as awful as she remembered it to be in her memory.

"What are we going to do now, San?" Rickon asked, suddenly appearing in front of her, already wearing his pajamas. She looked at the clock on the wall and noticed it was only eight. That was perhaps too early to put him to bed on a weekend, Sansa concluded though she didn't know what time he usually went to bed.

"We're going to watch some TV," she smiled, going to the living room with her youngest brother.

The four of them were playing pool but it seemed only Robb and Dickon, Sam's older brother, had some talent for it. Jon was leaning against the wall, looking melancholic as he silently surveyed the bar and Sam was dreamily staring at the girls sitting by the counter, the blue chalk of his cue now rubbing on his chin.

"She's pretty, isn't she?" Sam said softly, indicating at a brunette who was sitting with her back to them, wearing a yellow dress.

Jon merely shrugged his shoulders, not particularly interested in this kind of conversation. He liked Sam well enough but thought he was too much into girls for his own good. "Reasonably so," Dickon assented carefully before turning to Robb who was leaning over the pool table. "What do you think, Robb?"

Robb pocketed another stripped ball before lifting his gaze from the game to focus on the girl they were talking about. She had shoulder-length brown hair and was rather slim, that was all he could see from where he was standing. "She's not really my type." He replied, turning his attention back to the game of pool.

"What's your type then, Robb?" Jon asked with amusement, finally joining the conversation. "Wasn't Talisa a slim brunette too?" He teased and suddenly all the attention was on Robb.

He had to think about his answer for a moment. Talisa had been his first and only girlfriend, they had started dating at fifteen and broke up just now, three years later, right after prom. She would be going halfway across the country to college in Florida and neither of them wanted to be in a long distance relationship.

Truth was Robb had pictured his sister in his mind as soon as Jon asked him that. Despite exercising frequently as a cheerleader, Sansa's body had filled up considerably in the past year. She was no longer the skinny little thing she used to be, instead she had the body of a woman now. Her hips were rounder and Robb's gaze had diverted to her chest more than once. He was too ashamed to admit it, but he had dreamt about her at night more often than not, always waking up panting with a raging hard-on. That was one of the reasons he was happy to let Talisa go, he hadn't lusted after her in months. Instead, he now had wet dreams about his sister, something he felt terribly ashamed of. She was his younger sister for God's sake! What the fuck wrong with him?!

Apparently he took too long to answer because by the time he focused on the present again, the topic had already changed, and he sighed in relief. They were now talking what they were going to do after they finally finished high school in one week, except for Dickon who was already in his second year of economics at Washington State. Sam would be joining him to pursue a degree in literature and Jon was enrolling in the Police Academy. Robb had been admitted to study architecture in Tacoma. It wasn't a prestigious university, but the tuition was reasonable and it was close enough to home which meant he could commute daily.

Sansa was bored out of her mind. Margaery and Myrcella had gone to the lake and there was nothing good on the TV. Rickon had gone to bed over two hours ago and she was now thinking of doing the same. She had stayed with him until he fell asleep, reassuring him that nothing he saw in the scary movie was real. Bran and Arya were already asleep too (she had bothered to check!) and maybe a good night of sleep was all she needed but it had been over a year since she had last gone to bed on a decent hour on a weekend and she doubted her brain would even remember how to at this point.

Maybe she should be working on her personal statements already. Joffrey was already done with his and he had warned her Georgetown University's Pre-law program was highly competitive, so anything below exceptional wouldn't do. She had never been anything below exceptional at school anyway. First, she had skipped a year in elementary school which meant she would now be a senior starting September, along with Joffrey and Margaery who were one year older than her. And even beyond then, she had always been a honors student with some extracurricular activities here and there, but never particularly motivated. "You're lucky you're smart like this, otherwise I wouldn't be as tolerant with your behavior," Catelyn had told her, looking over Sansa's transcript only a few months ago. But instead of preparing her future, Sansa found herself in front of old Seinfeld reruns as she heard the front door open. It was only half past midnight, Robb hadn't stayed out late.

He finally appeared in the living room and Sansa spoke before he could even say anything. "They're all in bed, sleeping peacefully with their bellies full. No one got injured and no one died." She informed quickly and her brother chuckled before he made his way over to her to kiss her forehead before taking a seat on the other side of the couch, a bowl of popcorn between them.

"See, I knew you could be a responsible older sister if you wanted." He teased her with a grin on his face. She was still in the same dress she had worn to school only now it was crumpled around her as she sat cross-legged on the couch. Robb found himself staring at her milky white thighs, wondering if they felt as soft as they looked, if her skin would erupt in goose bumps if he lightly slid the tips of his fingers over them, from the inside of her knee all the way up to her… Robb felt all his blood rush to his groin as noticed with horror that he was getting hard just thinking about his sister who was sitting close by. Luckily for him, the room was dark and she was laughing at a stupid joke from the show.

"Don't get used to it, Robb," she replied with a short laugh as she gathered her long copper hair in her hand and threw it over her other shoulder, absentmindedly exposing her neck to him but he was fascinated by her collarbones all the same. "Tomorrow and Sunday, they're yours again." Sansa replied, trying to sound eager about her weekend plans but maybe she would just as happy lounging around the house or going to Target and buying some more useless stuff.

Suddenly, both of them heard someone running down the stairs and before Sansa could wonder who it was, Rickon threw open the door to the living room, holding his old teddy bear in his hand which he hadn't cared for in over two years. Robb immediately jumped to his feet and walked over to his younger brother, squatting down to his height. "Everything okay?" Robb asked softly, not wanting to wake Arya or Bran up now that the door was open. Rickon's only reply was to shake his head and Sansa addressed him a pointed stare from the couch. He better not snitch! "What is it then?" Robb inquired, tousling Rickon's hair and Sansa suddenly wanted to do the same with Robb's curls.

"I had a nightmare," RIckon sobbed, looking down at his feet to avoid Sansa's stare. That little bitch, she seethed.

"About what?" Robb was always like that, playing the perfect older brother in all circumstances. Sansa reckoned he was more of a father figure to Rickon than Ned was, mainly because their father was always away on business. He had been in San Diego for two months now without bothering to visit.

"Blair witch," Rickon replied and Sansa felt all the blood leave her face. "Sansa let me watch it with her," he snitched and she rolled her eyes despite knowing she was in for trouble now. Robb was going to yell at her, and then mom would do the same when she found out.

Robb stood up slowly and even though she could only see his back, she knew he was angry now. "You can sleep with me tonight," Robb told little Rickon. "Just keep the lights on and I'll be right there." Rickon nodded once before walking away and Sansa could hear him turn him all the lights on his way to Robb's room.

Sansa got up from the couch in an attempt to go to her room without Robb noticing, but he turned around just as she was tiptoeing to the door. "What were you thinking?" He hissed, his anger evident despite him keeping his voice down.

"It's just a movie, Robb," she replied calmly. "I told him every five minutes that it was a fake story and that there was no reason to be afraid." Besides, Rickon hadn't looked that scared when he was watching the movie and fell asleep quickly enough.

"How could you think he wouldn't have nightmares, Sansa?!" Robb blurted out with incredulity. "I remember very well when you stole the Ring VHS tape and watched it alone in your room. You slept in my bed for weeks!"

"I was six, Robb! Rickon is ten, it's not the same thing."

"Gosh, Sansa, he's nine." He sighed and Sansa felt somewhat uncomfortable then, she had really believed Rickon was ten. "Do you even care enough about any of us to know our birthdays? Do you even know my birthday?" For some reason his words stung. It was true that she wasn't the most caring or present sister, but they were still her family and she loved them all.

"January 25th," she replied acidly and could see the surprise on her brother's face. He really didn't think she'd remember. "I would never forget the day my life became a living hell!"

"I was born before you!" He argued, closing in the distance between them and Sansa felt scared for a moment. The last time someone had approached her like that, it had been Joffrey and he had halfway choked before she got him to stop.

"I don't care, I'm pretty sure I hated you even before I was born." Sansa regretted the words as soon as they left her mouth and she could see on her brother's face that she had hurt him. Shit!

Sansa closed her eyes tightly, trying to think of some lame apology but suddenly she felt his warm hand on the back of her head, his thumb on her jawline. Before she could figure out what was going on, his soft lips were on hers and instead of pushing him away, she pulled him closer to her by his t-shirt collar.

Robb's hands slid down to her waist, his fingers digging into her as she gasped with surprise, forgetting that she was in fact kissing her brother as she felt a tingling sensation in her stomach. His tongue was insistent against hers but she didn't feel threatened, not even when she was pushed against the wall, Robb's body pressed flushed against hers, his arousal undeniable. Sansa broke off their kiss, smirking as she drew a line with her tongue along his jaw instead, teasing him until he pulled her away with some strength and started kissing her again, even deeper this time, their teeth almost colliding.

"Robb!"

Both of them froze under Rickon's shout, immediately breaking apart. Still panting, Sansa breathed out in relief when she looked around the room and couldn't her find her little brother anywhere. She lifted her gaze to look at Robb and noticed he was already staring at her, the heaving of his chest matching hers.

Sansa realized with horror what they had just done and felt all color leave her face. If Rickon had walked in on them… she didn't even want to imagine it. What were they even thinking?! This was wrong on so many levels and yet Sansa was quite sure she would have continued making out with her brother if they hadn't been interrupted. She averted her gaze, feeling equally ashamed and embarrassed.

"Coming!" Robb shouted back and only then did she allow herself to look up, trying to slow down her breathing as she processed what had just happened.
