Oxytocin

Prologue

Note: Long time no see! Sorry for the long break, and I promise my unfinished stories are not abandoned, but I realized that at some point, I had stopped writing for myself and was instead writing for other people which caused me to become burnt out on writing. This idea popped in my head last night and I realized that this was exactly what I needed to fall back in love with writing. This is a much darker story than I usually write, but I am so excited and I hope you guys enjoy it as well! Updates will be at least every Wednesday, but knowing me I will probably update more often than that. Once this story is completed I will go back and look at my other stories with a fresh pair of eyes and begin updates on those as I have the inspriation. I hope that you guys give this story a chance even though it will be very different from my other stories. Addison and Meredith's relationship will not be the model for a healthy relationship, but as I continue further into my criminal psychology degree program I have found myself fascinated with twisted code of morals and ethics and wanted to explore that with my favorite gays.

I hope you guys enjoy and please don't be afraid to comment your thoughts!

Addison Montgomery was known for being a chameleon, able to blend into any crowd. She was known for the devilish glint in her cat-like eyes and her velvet lips painted scarlett. She could charm anyone and get them to tell her anything she wanted to hear. Addison was well known, but she was not known well. The mysterious redhead was not the type to open up or form meaningful relationships, instead she always had an agenda. At least until that evening in Seattle, the night everything changed. The night Addison Montgomery met the fascinating and elusive Meredith Grey.

It all started six months ago when Addison arrived in Seattle from New York. She was never a fan of Seattle, too much rain, but when you made a living killing people for money you went where the work was. Addison wasn't a monster, at least not in her eyes. Yes, she killed people in exchange for money, but she doesn't just take any job that she's offered. First, she looks into the person trying to hire her. Once or twice that little investigation ended in the realization that the one looking for an assassin was the real monster. When that happened, Addison would instead kill them. Sure, it meant that she didn't get paid, but as long as some filth was washed from the world did it matter? She wasn't in it for the money, though that was a nice bonus, Addison was in it for the good of humanity. There were a handful of times that Addison would receive a request for her services where the investigation resulted in it being a petty dispute and an overreaction that didn't warrant something as drastic as murder so she would reject the job. Often the person requesting her services had good reason and Addison relished in get paid for exterminating the cockroaches of the human race, it was nice to be compensated for the work that most are too scared to do, too scared of consequences to do what's right.

Addison knew from the moment she stepped off the plane that the job in Seattle would likely take a few months, a bit too high profile to take care of quickly. One of the secrets to being a good assassin was knowing how not to get caught. Every case was different, sometimes it was better to get it done quickly and get out of the area, but other times it was better to go slowly, build up to the grand crescendo and then escape while attention was diverted. She didn't mind the extended trip, the rain was dreadful, but she always had the best hotel arrangements.

While Addison was a gifted assassin who could talk her way into any room and get out without anyone seeing her she couldn't do this on her own. Her friend Callie happened to be gifted with computers and could hack her way into anything and Callie's wife Arizona was a master of fake documents. Addison knew that she couldn't complete her jobs without their help and she heavily compensated them for their help because at the end of the day Addison wasn't doing this for the money, she was doing it for the good of humanity.

A week into her Seattle surveillance on her latest target, a well known Neuro surgeon named Derek Shepherd. He had a nice smile, smug but nice, and decent hair but from what Addison could tell he was a misogynist sexist pig who saw women as objects. How did she come to that conclusion? Well, part of investigating her target meant getting to know the people around them, and Derek had a wife. Meredith Cora Shepherd, Née Grey. Meredith had an impressive résumé herself, not that her self absorbed husband ever let her show that. Despite skipping two grades and graduating from Harvard Medical School at twenty four, Derek didn't want Meredith working or showing her intelligence. They met when she was barely nineteen during her third year of undergrad. Derek was thirty four at the time and already an attending neurosurgeon. He was visiting an old friend who was a professor at Meredith's college when they ran into each other, her books flying everywhere, and he just knew that he had to have her. He helped her up and handed her books before walking her to her next class, and from there he kept finding reasons to be around her. They were then married on Meredith's twentieth birthday and while she continued going to undergrad followed by medical school, she would never get the chance to use her medical degree because Derek felt that a woman's purpose was to cook, clean, and take care of their husband. As much as the thought of being a housewife filled Meredith with disdain, Derek wasn't the type of man that accepted the answer no. Now at twenty six, Meredith was deeply unhappy and anxious for even the tiniest taste of rebellion. Shortly after Addison got into the assassin business she realized that sometimes the secret to a successful kill was spending less time stalking and investigating the intended mark and instead pouring more time into those closest to them. The moment that Addison laid eyes on Meredith Shepherd she knew that this would be one of those jobs, only this time there was a twist; her interest in Meredith wasn't solely due to her contact to kill Derek Shepherd, but because once she saw her, Addison had to have her for herself. No matter the cost.

Rain was falling like whispers from the heavens, cloaking the world in a blue-grey haze. It was a Monday, late morning. Seattle was bustling despite the dreary weather, its citizens used to the seemingly never-ending rain. Addison stood motionless beneath the awning of a closed flowershop, her back flush to damp brick building, in plain sight yet still hidden. She was dressed in all black, her auburn hair pulled back into a sleek bun, her scarlett lips the only source of vibrance in the droll Seattle greyscape. Raindrops pattered around her as her eyes scanned the other side of the street waiting for her to appear. Her preliminary research into Meredith Shepherd showed a pattern from which Meredith never deviated. Every Monday played out the same way, after Derek left for work Meredith would work around the house until approximately 11am, at which point she would drive downtown to the meat market Derek insisted she shop at and stop at a nearby coffee shop despite knowing that her husband didn't like her going anywhere without his explicit permission. It wasn't much, but that petty act of rebellion that had become ritual was one of the few things that kept Meredith from screaming as she was forced into a role that she never wanted to play.

Addison noticed her before Meredith had the chance to turn the corner, her honey blonde hair blowing chaotically in the wind. She was dressed conservatively in a cream turtleneck sweater tucked neatly into her warm brown dress pants, the look tied together with a pair of ankle booties and a long knitted cardigan. Addisons's eyes traveled to where the sleeve of Meredith's cardigan was slightly bunched up, showing the smooth ivory skin of her wrist, her heart beating so rapidly that Addison could see her pulse point moving even from her hiding spot across the street. Her jade green eyes darkened with an intoxicating lust as she watched Meredith move along the sidewalk quickly yet cautiously, like a wounded animal. A little bird. Addison's little bird. The redhead couldn't help but smirk to herself as she pictured herself unwrapping Meredith like a gift, kissing every new patch of silky skin that is revealed. Addison may not have known what Meredith's voice sounded like, but she could picture it in her head so vividly that she could hear it. Soft and submissive. Shaking with anticipation and desire. Begging so sweetly for Addison to remind her how it feels to be alive. Closing her eyes, Addison could almost see it. She could almost feel Meredith's skin beneath her finger tips, hot and needy. The smell of vanilla and lavender filling the room. The feel of their lips touching for the very first time. The sound of Meredith's whimpers and moans as Addison holds her down and teases her for hours. Oh, how she could picture it.

After allowing herself to get lost in her fantasies for a long moment, Addison opened her eyes and refocused on Meredith, sneakily slipping out of her hiding spot to follow Meredith as she turned the corner to the next block. The rain picked up slightly, but Addison didn't care. She was entranced by the sway of Meredith's hips, calling to her like a beacon. When Meredith stopped at a cross walk to cross the street to Addison's side, the redhead quickly hid in an opening of a side alley, her eyes glued to Meredith's hands as she brushed her rain soaked hair behind her ears. Her grey-blue were eyes distant and shadowed with melancholy and longing. For someone so young there was something so heavy about her, but instead of scaring Addison away that simply made the redhead want to know her even more. As Meredith carefully crossed the street Addison's eyes slid down her thin frame, licking her full lips as she once again thought of what a treat it would be to have Meredith at her mercy. She's read her file. Knows the address she leaves in the morning and returns to at night. Knows the name of the man she married, the name of the dog she once had, the childhood trauma she only half-admits to in old online journal entries that never got properly deleted. But files don't capture the way Meredith bites the inside of her cheek when she crosses a street, or how she shifts the coffee cup between her hands when they grow too cold. They don't show the way her lips part slightly when she's deep in thought, plump, unpainted lips that beg to be devoured. Addison lets the thought form in full, Meredith, beneath her, skin warm and damp not from rain but from heat. Fingers tangled in red curls. Voice cracking beneath the weight of surrender. Every part of her open for corruption.

Claimed. Owned.

One step closer, and Addison could reach her.But this isn't that kind of story. Not yet. Meredith crosses in front of her, oblivious. The scent of coffee and rain trails behind her. Addison drinks it in like the first pull of a cigarette after too long. Addictive. Wrong. Inevitable. She waits until Meredith disappears around the corner before stepping back into the shadows. The husband will die, eventually. That part is inevitable. But Meredith? She'd be ruined long before that. And Addison would be the one to do it.
