His focus drifted away once again, almost driving him mad. Tommy slowly let go of the pen he held in his tense hand, dropping it on the stack of documents that sat firmly on the dark desk. The room was filled with nothing but quiet sounds of glass meeting wood every few minutes, as the stocky bottle of whiskey emptied in an impressive time. His usually calm and steady breath hitched in his throat followed by an exhale, making him sound almost like a martyr.

Wide, intimidating silhouette of a strong man behind the desk wouldn't give it away, but his head felt heavy, yet was spinning with the troubles burdened upon his shoulders. His wife's harsh words rang loudly in his ears causing nothing but annoyance and burning frustration under his skin. As the time passed between his fingers, loose as sand, the reason for their marriage faded so successively, he could barely remember it. She couldn't be further away from his idea for a perfect or even remotely good wife, but he did what he had to. Like always. Her Romani upbringing and a tight bond with the Gold family left him with little to no choice after Arthur refused to take this responsibility upon himself.

When it came to heavy weights, it was always left for Tommy to handle. Fucking always.

Letting out a deep breath, Thomas leaned back in his comfortable seat, popping a few buttons of his shirt open, as he carelessly tossed his red tie aside. In the comfort of his office, Tommy let his mind wander towards the thoughts so unwanted and forbidden, they rarely were present outside of his space. Knowing his own weakness, Thomas ground his teeth for a short moment at the realisation of how his control started slipping away. The farther down the rabbit hole his brain went, the stronger the burning bothered him.

After years of letting his manly urges slowly starve to death, dealing with the humiliation and frustration that came with being married to a woman so insufferable, she managed to kill his sex drive, THE thought didn't come unnoticed.

At first, it came and went. The next time it happened, Thomas’ eyes wandered to HER pale legs for a little too long before blinking the infatuation away. After that point… he lost count. He was only a man, after all.

Squeezing the bridge of his nose, Tommy breathed in deeply, silently cursing out the headaches he's been dealing with lately. Tommy imagined the smoke from his cigarette filling his body with hope of cleansing him from all thoughts of Y/N.

The hope died pretty quickly, as it tended to happen for people like him: people stained with burdening responsibilities and the weight of the world on their back.

As her image simmered behind his closed eyelids, his brows furrowed in worry.

What a beautiful distraction she was. A forbidden fruit, an evil snake from the depths of Eden, poking on his self-control and morals, whispering unacceptable yet impossibly beautiful ideas straight into his ear, driving the poor man mad. Leaving him burning hot and yearning for her touch. She tempted him with her beauty everyday for the last year. Her beautiful, innocent eyes, which looked nothing like her mother's. Her eyes weren’t tainted by greed and the dark shadow of death, which surely came from years of living in Birmingham. Lurking for people at every turn.

Y/N was different. She was raised away from dingy cities, in fields and forests, travelling from town to town with her father and rest of the family. Y/N lived far away from her sad excuse of a mother, yet still ended up having to suffer her presence once Patrick Y/L/N lost his battle to cancer. Not even the strongest of Romani spells could stand a chance against a body leaning so hard towards the path of self-destruction.

That's how she ended up here, at Arrow House with a disgraceful mother and stepfather who was barely present and silently pining after her.

The sweet girl grew to trust him, after several months of avoiding him.

Thomas didn't mind it at the beginning. He had no interest in fathering an adult whom he was closer with in age than with his own wife.

Y/N soon learned after moving to Arrow House that her mother had little to no interest in getting to know her, at any level that matters. The important thing was to present herself well in front of people, the audience, as she liked to call them. The audience watched every move of the Shelby family quite carefully. If Marilyn Shelby was anything more than shallow, it was definitely demanding. For peace, Thomas had no issues in letting her spend his money left and right, as long as it kept her mouth shut. With practically nobody left to trust, Y/N started appreciating Tommy's presence, even if it was entirely silent.

That's how the first two months passed. They lived their lives around each other without more than a few words when necessary, yet his presence became associated with peace and safety in her inexperienced mind. His stillness and calm, husky voice was a source of much needed comfort.

With each passing day, her trust grew as she let the guard down, Y/N’s body language clearly changed, not going unnoticed to Tommy’s bright knowing eyes

Suddenly, a loud knock on the door echoed throughout the spacious room, violently ripping Thomas’ hazy mind out of the infatuating thoughts.

“Tommy?” He heard from the door, and his head turned to face her. There she stood, barefoot, wrapped in a robe at least two sizes too big for her thin frame. Her long hair flowed down her back. Y/N’s intense gaze left him burning again, as Thomas cleared his throat.

“Come in, angel” He let out, his eyes grazing over her skin. He was braver than usual, the alcohol in his bloodstream made it more difficult to keep his painful desire hidden.

Without a thought, Y/N closed the door behind her back, making her way through the office, slumping on the chair in front of his desk. Her eyes were absent, not meeting his gaze even once as she silently looked around his desk. “What's burdening your mind?” His voice cut the air like a knife, making her finally look at him.

Y/N’s big eyes seemed teary, making his heart stop for a second as he sat up straighter in the armchair. When his brows furrowed impatiently, the dam broke and quiet sobs pushed past her lips.

Watching her slowly break apart, Thomas ran a hand through his hair before getting up and rounding the desk, eventually taking his place on the edge of it. Leaning down, his rough hand came to rest on her shoulder. He wanted nothing but to feel her close and now was a perfect occasion.

Upon feeling his touch, Y/N suddenly rose from her seat, stepped forward, and wrapped her arms around his core, seeking comfort. This Tommy did not expect.

His breath hitched and his brain was barely able to process the heat of her body pressed to his own. He trembled slightly and hoped she wouldn’t notice. A couple moments later he embraced her carefully, like she was made of porcelain, able to be shattered into a million pieces if held too tightly.

“She… She said it's over. That I've lived here long enough to figure out my life without depending on her—your money.” Her voice was quiet, fragile even. The genuine fear and urgency she held him with, made Tommy's heart beat faster. His other hand came to rest on the back of her head, petting it slowly as she continued at her own pace. “I’m… I'm not ready but—but I know she's right, I shouldn't… be here that long.” Y/N kept mumbling as her forehead pressed into his shirt covered collarbone. His hands’ movement came to a stop at her words. Tommy slowly peeled her away as his fingers grasped her chin. His gaze fell to her soft pink lips and he immediately regretted it as his mouth went dry for a second. Regaining his composure, he spoke.

“Angel, your home is here. You're not going anywhere anytime soon, and your mother is… not in charge. Not under my roof, eh?” His voice was deep, a little too deep for his liking even, as Tommy tried to light up the mood slightly. Not wanting her to see the way his pupils dilated seeing her so close. The way his breathing got deeper, chest raising and falling visibly. Her lips just a small reach away, tempting him like never before. The stirring in his lower stomach made it difficult to think, but Tommy knew one thing for sure, and it was that he wouldn't let her leave. Not his Angel.

~~

The next couple days Thomas tried to spend more time at home than in his office, knowing how Y/N needed him to be around. The more time they spent around each other, the less guilt he felt.

He liked it. He liked looking with desire, and not feeling burdened with guilt. Looking in her eyes during the late nights spent in his office, slumped in the chair which she called hers already.

And he? He didn't mind, not one bit. Deep down, he thought about it more than he should have. Even if she felt like calling HIM her own, Tommy wouldn't mind.

Driving back home, the gravelly road scritched under the heavy weight of his car, small turbulence in the cabin making no difference, as he barely paid attention to the road.

Only when the high, black fence started showing from around the corner, he forced himself to focus. Taking the right turn, smoothly getting on his property. The shaking of the car fading into oblivion as the gravel road turned into expensive tiles by the mansion.

He thought he had more time to solve the issue, Thomas thought, as a suitcase fell out of the window, missing his Bentley by less than ten inches.

Eyeing the mess, he mentally prepared himself for what to expect after crossing the entrance. Grabbing his suitcase, he swiftly got out of the car, quickly making his way to the door before getting inside. The screaming and Marilyn's high pitched, dramatic voice could be heard even before he opened the door.

Without a second thought, he climbed the stairs as the two women came into the view. Marilyn held tightly onto her daughter's hair, pulling down clearly, judging from Y/N’s pained expression as she sobbed.

“Enough!” Thomas boomed, quickly grabbing onto his wife's wrist, his rough, calloused hand squeezing so tightly it surely would leave bruises. The older woman gasped, pulling her hand back as she took a step back. Her eyes narrowed as soon as her eyes fell on his face, gazing with contempt and anger.

“This little whore stole my pearls! I found them in her room!” She growled, clutching the jewellery close to her chest as she tried to lunge forward again, stopped by Tommy's broad chest. “If I see her in this house by tomorrow, I'm going to put her down like a bloody dog, Thomas! Tomorrow!” She kept yelling, but he could still hear the quiet sobbing from the woman behind him. Y/n cried, holding onto her scalp that burned hellishly. Bruises on her face already getting darker while heavy tears decorated her beautiful face one after the other with no end.

Tommy's blood boiled, veins on his neck protruding from the heated anger he felt deep inside. His self-control ran thin as his hands shook with the urge.

“Y/N, go to your room.” He instructed, in a demanding voice. One of his hands sneaked back to give her small fingers a knowing squeeze. Feeling it, she nodded, wiping her tears away as she slowly let go of the material from the back of his coat.

Marilyn's cold, green eyes followed after her daughter, contempt and hatred visible. She hated how much attention she stole from Tommy ever since appearing in Arrow house. She hated how much money he kept spending on her.

Marilyn felt robbed, like it all belonged to her.

Jealousy rushed through her veins, even though her heart was stone cold. No feelings for Thomas Shelby were held, but she claimed rights to him nevertheless. After all, It was impossible to love people like him anyway, right? Marilyn thought.

Her hand met his cheek with a loud slap, as she took a step forward. Looking him in the eyes she felt the upper hand.

“You think I'm fucking stupid? Don't you think I see the way you look at this little whore?” She hissed with poison, her red smeared lipstick making her look even less approachable than usually. “If I see her here in the morning, all Birmingham will know about your perverted urges.” She finished with a whisper, her shaky hand petting his cheek mockingly, not caring about the way he… watched her. Blue colour long gone, replaced by the deep shade of the night sky.

Only then her heart skipped a beat as she realised she took a step too far. Shallow breath pushing past her lips. Eyes widened with confusion, pierced with fear as blood ran cold.

But it was too late.

“Goodnight, Marilyn”

~~

Y/N lay in her bed, clock ticking in the background, reminding her of how late it was. Darkness swallowing every inch of the room besides a small stream of light coming through the window from the street lamp. Heart thumping in her chest the only sound she could hear… before the music started playing. The melody grew louder, the familiar rhythm echoing upstairs coming from the gramophone standing in the corner of the corridor. A song she knew all too well after spending many quiet nights in Thomas' office. Note by note the tension increased with the tempo of the piano playing, coming to a peak as the door creaked open, barely noticeable in the dark.

Her eyes, used to the darkness already, noticed the flash of blue irises and the silhouette she knew too well. Breath hitched in her throat with each step he took.

Second by second, note by note. When the song abruptly came to a halt, his hands touched her face. His face hovered over her own, lips so close she could see every detail.

“Tommy” She breathed out softly, but before Y/N could continue, the song resounded again, almost like urging him to move faster. The tension broke, tearing a painfully deep sigh from his throat as his chapped lips pressed against her own. Y/N’s eyes squeezed shut, taken aback by the boldness of his actions. Her lack of experience creeping up her spine, causing anxiety but Thomas didn't give her enough space to dwell on the details. Crushing all of them with his touch, touching each and every inch of her soft skin with his calloused hands, causing some discomfort which he immediately softened with kisses. Music in the background seemed to set the pace, and as the thempo increased, his touch grew impatient.

“We—We can't” She managed to whisper, even though her throat was dry with a need she didn't understand.

“It's just us, angel. Me and you” He growled, his eyes holding the wilderness he was unable to hold back after all this time. His body tense and firm like a statue, as he kept moulding her flesh to his liking… and she let him, because Y/N didn't know any better. She didn't want to know any better.

Some sudden sounds kept piercing the music, catching Y/N’s attention for a millisecond before he'd make her forget again, touching and pulling needily. Soon enough her body was bare for him to take. Greedy eyes taking in every detail he could see in the dark, swallowing every sound from her mouth, stroking her womanhood skillfully, wanting nothing but to worship every soft, welcoming inch of her perfect heat.

“Just me and you” He echoed, grabbing both of her wrists and pinning them softly above her head, taking control of her along with the situation.

Music seemed to be never ending, as he slipped into her body, stretching and pushing his way into the space he claimed for himself only. Her innocence taken away so abruptly and harshly, yet she never felt so loved and wanted before.

“Tommy, I–” She moaned, head lifting off the bed to find his lips, which he immediately understood, giving into every need and every urge.

Spending all the strength he had to give her time, and not let the animalistic urges take over fully, as she needed… guidance.

“I know” he responded, moving slowly, feeling as she successively accepted his cock, relaxing into his arms and whimpering beautifully.

He was patient, slow and understanding… until he couldn't anymore, moving increasingly faster and harder, his hands squeezing her wrists a little too tight but they were both lost. Lost in the forbidden dance led by the embers smouldering in their chests, intensified by the music they both heard. Tangled in the forbidden, breathtakingly beautiful dance.

Y/N let him paw at her skin needily, pushing into her deep and fast, taking everything he needed. Lost in the experience and in the intense being that Thomas Shelby was.

Maybe if she was just a little less gone, a little more meticulous, she'd notice the dark red stains on his shirt.

The raw obsession in his touch ever since he held her for the first time so innocently. The metallic scent of blood on his skin.

Tommy couldn't let anything and anyone separate them, after all.

Devil and his angel.
