01 – Comfort
They always manage to find comfort in each other; whether they have been working solo or as a pair, they know that the other will always be able to understand.
02 – Kiss
Their first kiss is heated and passionate and meaningless, a last-ditch effort to hide in plain sight while running from the policie in Prague; but every kiss after carries its own unique message.
03 – Soft
Their bed is made up of soft pillows and warm blankets and clean sheets to make up for hard bodies and cold hearts and blood-stained hands.
04 – Pain
Nothing hurt more than seeing him with blue eyes and knowing that for once, he didn't have her back.
05 – Potatoes
Clint is the only person who knows that Natasha is allergic to potatoes, and sometimes has to remind her.
06 – Rain
Though she would never admit it, Natasha remembers a dream she had once as a little girl of being kissed in the rain; she never told Clint but when they were stuck in the rainforest waiting for an extraction that seemed like it would never come, Clint made sure to kiss her.
07 – Chocolate
Her favorite is the sweet, white chocolate that melts on her tongue; his is the dark, bitter chocolate that tastes like tart raspberries
08 – Happiness
Natasha knows happiness; when she was still Natalia, the Red Room's prized possession, happiness was a memory of her mother singing a lullaby or her father reading her a story; After the Red Room, it's the sound of coarse laughter and the feeling of calloused hands, the sight of blonde hair and blue eyes and the sure feeling of someone – Clint – always having her back.
09 – Telephone
They disconnect their phones at least once a week; it's a way for them to escape reality with each other, if only for just a little while.
10 – Ears
Clint has sensitive ears; just not quite as sensitive as his partner's.
11 – Name
He was the first person to acknowledge her new name among the SHIELD ranks, but he was not the first to give her a nickname.
12 - Sensual
Natasha is a master with knives; but she quickly learns exactly how sensual it is to watch Clint work.
13 – Death
Neither of them fears death; death is an old friend to both of them, simply biding his time, and they know that when the time comes they more likely than not will greet him together.
14 – Sex
They work together in the field for years before they finally end up in the bedroom, but their chemistry translates amazingly well.
15 – Touch
Touch transmits so many things for the both of them; months after she defected to SHIELD, Natasha wouldn't allow anyone near her, not even the instructors sent to evaluate her, except for Clint, and after he loses his hearing, each touch takes on a whole new meaning for the both of them.
16 – Weakness
They both have their weaknesses; little things not written in their files, things that only the other know, and that's the way it's going to stay.
17 – Tears
Natasha doesn't cry for anyone to see, not real tears; the only people who have ever seen her really cry are dead…except for Clint, who has been sworn to secrecy for fear of his life.
18 – Speed
Natasha loves speed; as a part of the Red Room, the closest thing she ever felt to freedom was when she was driving as fast as possible in whatever car they provided for her and it's the reason she lets Clint drive, why she loves it when he flies – he's the only person she knows who can drive faster than she can.
19 – Wind
Clint will always remember the sight of Natasha standing on the balcony of their shared hotel room two days after their evacuation from the shit-storm that was Budapest; to him, nothing could compare to how beautiful she looked with her hair blowing in the wind.
20 – Freedom
Natasha never thought she would ever know the feeling of real freedom until she met Clint.
21 – Life
They have both seen and done horrible things in their lives, yet despite all of this they know about life, and life would be meaningless without someone to share it with, without each other.
22 – Jealousy
Clint doesn't admit it, but whenever Natasha has to seduce a target, she can tell that the jealousy is there, especially afterwards; she can tell by the way his hands glide over her body as he helps her undress, by the way he whispers in her ear, and by the way he holds her at night when they are sleeping.
23 – Hands
The thing she loves most about Clint is his hands; strong and calloused from years of training, but unnervingly gentle all the same.
24 – Taste
He's never tasted anything as sweet as her lips.
25 – Devotion
To her country, to the Red Room, to her handlers, it was devotion forced upon her by survival instinct and necessity; Clint is the one person, and SHIELD is the one thing, that she chose devotion for.
26 – Forever
It may not be possible – logically they both know that – but they both secretly think that they've got the closest thing to forever there is.
27 – Blood
They can't stand the sight of their blood on each other's hands, even if they weren't the ones who caused it.
28 – Sickness
Neither of them gets sick very often, but Clint does so more often than she does; she'd never admit it to him, but she doesn't mind taking care of him when he does.
29 – Melody
Clint loves the old Russian melodies she sometimes hums or sings when she thinks that nobody is around to listen.
30 – Star
After the bad missions, the ones that mess with their heads, Natasha sits outside with Clint at the highest point he can find and lets him point out the stars and constellations.
31 – Home
The only permanent home they've ever had is with each other.
32 – Confusion
Nothing will ever be as confusing as the first time she went on a solo mission and he woke up to realize she was no longer in their bed.
33 – Fear
Clint is the only person she has ever trusted enough to confide her fears in.
34 – Lightning/Thunder
Even before they started permanently sharing living quarters, they always shared a bed during thunderstorms; so that with each peal of thunder and each crack of lightning, neither has to face the nightmares alone
35 – Bonds
She freed herself from her handlers, but she thinks that Clint is the one who really severed the bonds holding her to the Red Room, with single arrow just inches from its mark in a dark alley in St. Petersburg.
36 – Market
They both know exactly how much they're worth on the black market – they have made many enemies over the years after all – which is why they always watch each other's backs.
37 – Technology
One of the things they love most about modern technology is the medicine; without them, they both would have been dead years before they had been able to meet each other.
38 – Gift
Natasha insists that the best gift Clint ever could have given her was the choice to live or die; it was the first time anyone had ever let her choose anything in her life before.
39 – Smile
Clint doesn't smile often around people other than Natasha and Coulson; so when they're waiting for Thor to take Loki back to Asgard, Natasha makes sure to make him crack a smile, just to spite the would-be God-king.
40 – Innocence
Neither of them has been innocent since they were children; which is why when Natasha brings home a young girl of about five after a mission to break a child-trafficking ring, he doesn't protest at all.
41 – Completion
As corny as it is, the first time they fall into bed together and he takes the time to make love to her instead of just having sex with he, she can't help but think that maybe that's what completion feels like.
42 – Clouds
Occasionally, when the world doesn't need saving and SHIELD doesn't need their skills, they take the time to be children for a few hours and pick out shapes in the clouds.
43 – Sky
The reason he prefers the high ground, she learns, is not always because of the vantage point; it's often because of the view of the sky as well.
44 – Heaven
There's too much red in both of their ledgers for either one of them to dream such a place could even exist; but they can still hope.
45 – Hell
Hell is something they've both seen in person; Abidjan, Budapest, and even New York, all fall under their personal definitions of the word
46 – Sun
As much as they hate early mornings, being able to see the sun means that they've been able to survive another night, another mission, another fight.
47 – Moon
He will forever insist that the moon will never look more beautiful than if she were standing in front of it.
48 – Waves
The both of them will always remember the beach in Sri Lanka, where the waves carried away the bathing suit that she wasn't using anyway but still made him pay for.
49 – Hair
Her hair is one of the things he loves most; not the length, but the vibrant red color that she once told him she got from her mother – it's the one thing she's most proud of.
50 – Supernova
When they do come together for the first time after New York, it's not heated or rushed like almost every other time; this time it's slow and passionate, ending in a supernova of gasping breaths and biting nails and hyper-sensitive skin.

A/N: This was a first for me; I've never done a 50 sentence prompt before, but this was kind of fun! Next one should be up relatively soon-ish.
