At the age of twenty-two, you felt like life had completely been perfect. How it could get any better than this - well, it couldn't in your mind. Your boyfriend was to be home within the hour, a testament he made earlier this morning. 7PM sharp, he would be here.
So, you began to work on his favorite dish. The door bell rang making you stop the cutting that your magic was doing all over the room as you moved out of the kitchen to the front door. A huge smile plastered on your face as you giggled out, "Sirius, did you forget your key again? You know the spell-" Your eyes finally met with ones similar to your own, your parents. "Hello.."
"Let us in, dear. It is freezing out here!"
Not that you didn't love your parents, in fact you love them with all your heart - but you weren't expecting them. "What are you doing here?"
"Can't we just visit our daughter?" Your father asked the snowflakes immediately melting as he casted a spell to dry himself and your mother off.
"Of course, it just caught me a bit - ya know, off guard is all."
They smiled gently at you before giving a grim look to one another. "There is a urgent matter, that is why we are here."
"Whatever is the matter?" The enchanted coat rack reached out to grab their coats as they shrugged them off.
Their eyes refused to meet your own as they stared back at each other as if speaking through them. When they chose not to say a word, your eyebrows furrowed. "Well, out with it please. If you've come all this way, surely it is of the utmost importance."
"Yes, well, you see," Your mother started to speak but cut herself off with her own eyebrows furrowing. You turned to your father who looked like he'd seen a ghost.
"We- You're to be married to Regulus Black this upcoming Spring."
"What?"
"It is, you know - not without great difficulty to do such a thing but we had no choice. We owe their family a huge debt, one that can be paid off if you marry Regulus Black."
You laughed bitterly before grinding your teeth together. "Surely you didn't."
"We apologize but please you have to understand they threatened us."
"Threatened you?" Your anger diminished slight at the newfound information.
"When we, of course, refused to agree to the proposal - they went off the handle preparing to kill us and turn us over to you-know-who for harboring the information from The Orders whereabouts."
You felt like a dementor had come through your window and had stolen your soul at the moment. Why had they been so adamant about you? They knew that Sirius was your boyfriend, perhaps it was all a cruel plan to get back at him for leaving.
"I cannot marry a man I do not love, I barely spoke to the boy in school."
Both of your parents got on their knees, their eyes pleading. "Please."
The guilt ate you alive, if you refused your family would be brought to him where they would be tortured for information about anything and everything. "I will not marry him, but I will let you set up a meeting. Maybe they would listen to reason if I was there."
They stood from where they had previously been groveling, their lips pressing kisses to your cheeks. Their own cheeks had tears cascading down them. "We will figure it out, we will set up the meeting. We love you."
They almost immediately left the house after saying so, running into your boyfriend with small short greetings. He ran inside your shared placed with a smile. "Hello, love. Might I say, you look rather-" His eyes narrowed taking in the sight of your face. "What is the matter?" He rushed over to you, grabbing your hands.
"Your mind is about to be blown, I mean it."
"Is it? My other head wouldn't mind being blown either." He tried to make the situation light hearted but it only ended with you smacking his chest.
"I'm being serious."
"How can you be serious when I am him?" He chuckled out making you roll your eyes before smiling.
"Sirius!"
"Alright, alright - what is bothering my beloved so?" He placed multiple little kisses all over your face as he awaited your answer. You sighed contently before bringing yourself back to reality. The house of Black had threatened your family with such cruelty it left you feeling sick.
"Your family."
"My family?"
"Yes, they threatened to take my family in front of you-know-who to be tortured if I do not marry your brother."
His face seemed to morph into many different emotions before settling on a very unnerving one. "They did, did they?"
You nodded. "I have already told my parents no, but I would speak with them about this little debacle."
"I would like to go with you when you do, teach them a lesson to not mess with my girl."
You smiled at him, a gentle and reassuring one. "Sirius, I think it would be best if I went alone but-"
"What? Why?"
"You think your family would take my proposition over the marriage if you were there?"
Instead of being offended, Sirius merely laughed loudly. "I suppose you're right as always, love."
"Something you seem to forget about a lot."
His laughter once again rung throughout the small home. "Right you are once again. What proposition are thinking of making?"
"I don't know yet, I will ask my family what exactly is owed so that I know the severity of the whole ordeal."
"I know you're a smart girl but I worry they might hurt you if you go alone. Bring someone, anyone - please." He lips brushed against your knuckles, kissing them ever so gently before kissing up your arm. His kisses eventually led to your mouth, the kiss the ensued was full of passion. His tongue fought against your own for dominance.
"Love, say it please."
"Say what?"
"Say you won't go alone."
"I won't."
His stormy grey eyes stared up at you as his kisses began to wonder farther below until he reached the skirt you were wearing. His kisses pressed onto your clothed heat, making you arch from the warmness of his lips. "I don't know what I would do without you," He started as his fingers slowly slid your panties off your body. "Without her."
Her? Oh, he was referencing to your pussy. His tongue took one long swipe up before his mouth covered the top part of your pussy, sucking on it hard making you wince but cry out at the same time. Your fingers ran through his hair, gripping at it occasionally.
"I would kill them all if they even touched a single strand of hair on your body." He spoke once more, pulling away before sticking one finger inside of you then another.
You were too lost in pleasure to fully understand his words. "Sirius, oh fuck-"
His fingers were stretching you out so much with his other hand was drawing out his name on your clit. "That's it, love." He felt your walls tightening around his fingers, with your toes curling and eyes rolling back. "You can't marry him, he would never get you like this." He stared down at you from the bridge of his nose, it would look almost terrifying if you didn't know him. But you did, he was your Sirius.
"Sirius, don't talk like that please." He removed his hands, licking up the juice from both fingers.
"Fuck, love- you always taste so perfect, so mine." He completely ignored you as he continued to lick his fingers clean. He looked like a hungry dog when given scraps as he did so. The zipper to his own pants was pulled down by you, but he finished taking it all off before lining himself to push himself inside you.
"If I get you pregnant, they would have to find someone else for their little reggie." His thrust in was gentle, caring but after you got used to the stretch - they became rough and erratic. "Who do they think they are? This fucking pussy is mine, you're mine. Your laughter, your smile, your-"
"Sirius, please - it's all yours." You felt the building pressure once more as he relentlessly kept hitting the certain spot that had you moaning and shaking.
"That's right, it's all mine." His thrusts slowed slight as his eyes closed and a groan left his lips. "My pretty girl." You felt him twitching inside of you as he stopped completely, he looked so ethereal like this. His long black hair was messily hanging off his shoulders, his eyes shut.
"My pretty boy."
His eyes opened as he smiled at you. "That I am. Now, let's get you cleaned up. I'll finish making dinner after, yeah?" His arms wrapped underneath you, picking you up with such ease it scared you. The hold was bridal style; so ironic it nearly made you laugh.
One thing was for sure, if you had to meet them tomorrow you wouldn't be able to walk. Maybe that was Sirius's plan all along though, you wouldn't put it past him.
As the night progressed, Sirius snoring was all that could be heard with his arm lazily around your stomach. Your eyes stared at the enchanted ceiling, the stars from it shone bright. You had barely spoken to Regulus in all your time at Hogwarts, not only that but you were a Gryffindor. Doesn't the Black family hate Gryffindors and all they stand for?
You're pretty sure they hate anyone who wasn't like them though, that was evident with Regulus one of the times you had come across him. One particular time, you did stand up for him but how could he even remember it was his first year while it was your third.
There was four or five times all together that you could think of ever actually speaking to him.

The sound of children laughter run throughout the corridors, but your eyes remained on the first year that sat by the lake. His eyes seemed very sad as he slouched over, a small sigh from what you could tell left his lips. How could someone so young be so upset?
That is why you decided to go see what was wrong. A wide smile played at your lips as you jumped scared him making him jump slightly before scowling.
"What do you want?" He asked, his grey eyes staring at you with annoyance.
"Just wanted to see if I could sit with you is all."
"No you may not." He huffed out with a roll of his eyes before returning to moping. You nodded at him.
"Thank you, kind sir." You said to him as you plopped yourself down beside him despite his protests. "I heard if you look sad enough by the black lake - the sirens will lure you in to eat you."
"Do you typically believe in such fantasies? I heard that if someone is annoying you - the werewolves will eat them for you." His sarcastic tone made you grimace before laughing.
"I guess I will be getting eaten by a big bad wolf then, no?"
A small smile almost made its way to his face but he scowled at the last moment. "Yes, so - leave me be."
"Alright, alright. I'm [Name] [Last Name] by the way."
"I do not wish to give you my name now go, you're disturbing me."
He sure was a snobbish little boy. "Very well, have a good day make sure the sirens stay away by having a smile on your face."
"Shove off."
Your laughter followed you unaware of the eyes that did as well.
1975
The Yule Ball was around the corner many students rushed to get dates and outfits for the occasion - one of those people included yourself. Thankfully, a certain someone you had a crush on for a while had asked you to the dance. Sirius Black, at least - that is what you thought.
You had received a note the previous day.
Attend the Yule Ball with me, you won't regret it in the slightest I can assure you.
- Black
Of course, you wrote back a yes immediately tying it to the owl that flew in your window. You felt so ecstatic - Sirius had asked you to the dance. The though of it left you too excited to sleep, you wanted to celebrate with a little sweet treat from the kitchens.
Carefully wandering around the corridors, it would be scary if you weren't hyped up on the thought of dancing with the most eligible boy in your year - your house at that. The most handsome boy you had ever seen before, your eyes scanned the area before they landed on the sight of the kitchen doors.
A small smile formed on your lips as you opened them, your eyes widened in shock when you saw some Slytherins in there. If you knew any better, they were a few years younger than you.
"{Name}!"
You looked at the black haired boy who beamed your way, he walked towards you and grabbed your hands. "I was quite pleased when you agreed to-"
The confusion wore off when a loud crash took you from it, you whipped your head to his friends that were fighting over a piece of food. You chuckled lightly before removing your hands from Regulus's. "I guess there is no more food left then?"
"Not when your friends are as fat as mine are."
"We heard that!" They screamed at him, Regulus stared at you smiling softly.
"As I was saying-"
You gasped and smiled at him. "Your brother invited me to the dance, isn't that amazing?"
"....what?" His face dropped.
You shook that thought from your mind. You hated the way his face had dropped, you never knew why either.
1976
This was the year you graduate, a splendid one at that. Every 7th year was glowing - some were not due to the fact of the exams. You had no reason to really worry, studies had typically come natural to you besides your boyfriend is the best tutor.
He already taught you so much within the past year of being together - your face heated up at certain thoughts. "Get your mind out of the gutter, [last name]." You spoke to yourself before running into someone nearly falling from the impact but you managed to stay grounded.
"Sorry-" Your eyes met with Regulus Black who only stared down at you, his eyes seemed to burn a hole through your own. Truly, a very intimidating man. If Sirius had turned out like that, you couldn't imagine the fear he would instill in people.
"Oh, little black. Sorry to run into you, I wasn't thinking."
"Oh, I know I heard your little tiff with yourself."
You smiled at him brightly. "I suppose you just have to put yourself in place."
"You're very odd."
"Thank you."
"You're not typically my brothers type, I find it odd that you're odd."
You laughed at that before abruptly stopping. Not his brothers type? What does that mean?
"What do you mean, reggie?"
He never seemed to quarrel with you when you gave him stupid little nicknames, after learning his name you just took it upon yourself to bestow him with so many.
"Nothing to concern yourself with. Would you like to accompany me to the dining hall? I am quite famished."
"You speak like an old man, ya know that - don't you oh wise one?" You followed beside him as the two of you walked towards the food.
"Says the old lady."
"Old lady? Excuse me, I am seventeen years old - I still have my whole life ahead of me, young man."
"If you say so."
You both stared at one another before letting out chuckles. "Well then listen to your elder, I don't wish to be called old."
"I don't wish to be called many things yet you call me them anyways."
"That is very offensive, all my nicknames are made with love and sincerity."
A small, short smile spread across his face. "With love, huh?"
"Yes, my dear-" A yelp left your lips as you were pulled roughly in the opposite direction of where you were headed. Regulus head snapped quickly to see what happened only to come face to face with Sirius - who looked very pissed off.
"I've told you to leave her alone, Regulus." Sirius grabbed ahold of your wrist dragging you behind him - far away from his little brother.
"He's exactly like my family, ya know? It's best you stay away from him, he's no good." He finally spoke to you, as he stopped after putting quite the distance between the Slytherin and the two of you.
And so you listened, you had no real connection to the younger boy anyways.

There were occasional times you found the other Black staring at you, but you would always play it off that it was because you were dating his older brother. Siblings get curious about who their sibling is dating - so you never thought much into it. You still don't, you think perhaps this was a move by his mother. That woman hated Sirius for being a so-called blood traitor. You supposed you never knew why he stared before you started dating his brother though.
You stopped to think more about all your encounters with the younger sibling, the one whom your family wanted you to marry. Perhaps, there was more times than those three you randomly thought of. You constantly did pass by him giving him little nicknames, occasionally chatting here and there in between classes, even laughing at a mishap in the library together. You felt your mind tightening like it was fighting you as you tried to remember all those years ago - most of them were a blur.
Perhaps Regulus Black was your friend if you thought hard enough about it, one you never spoke to again after leaving Hogwarts. Maybe this was actually his way to get back at you for ignoring him all these years, hopefully not. Hopefully, he would see reason where his parents did not.
With that thought in mind, you cuddled into your boyfriend for warmth which he instinctively pulled you closer. Tomorrow was a new day, always.
.

The time had come for you to visit your family - ask them what they owe to the most ancient house of Black. Perhaps, if it were low enough you could pay it off with time instead of selling yourself out. It wasn't uncommon for other pureblood families to put each other in binds so that they owe them - most of the time it did end up in marriage alongside other little offerings. What more can a person give than their own daughter or son?
"Mum?" You voice rang out in the nearly empty mansion; the furniture was there but no souls seem to occupy it. "Hmm, I guess no one is home."
That was what you had thought until the sound of people speaking to one another could be heard, you rounded the corner to head in the direction when a voice spoke.
"Here to annoy me for the rest of my given life?" Your eyes landed on the tall man that looked similar to your boyfriend, only less handsome. A smug smirk was displayed on his face, making you roll your eyes and cross your arms.
"Quite the opposite, I am here to propose a better idea."
You were unaware of how his eyes sharpened as those words left your mouth, or the way his jaw tightened. His blue, icy eyes seem to darken at the idea of you even thinking about denying him the marriage he has wanted since his first year of Hogwarts.
