Just like candy - Sirius Black x Reader *smut*

Just like candy

  You were Remus' twin sister. That's all you could ever be. To him. He could never look at you in any different way. The shy, quiet and introvert sister. Little did you know that he thought of you as enigmatic, inspiring and exceptional.
You were friends with the Marauders-your brother being one-since day one. They were lovely. Kind and funny, stupid at some point, even annoying. But they were your brothers. Well, not everyone. You held a bit more for one in particular. But so did every other girl in the school. That's why you stopped holding on to hope. That and because Remus would flip. Thankfully he hadn't had the slightest idea. James though... he knew everything-he was a bit more of a brother than your own brother. You could actually open up about that kind of things. Yes, Lily was wonderful but the girl was utterly dense to her own feelings. James felt torn. He had promised you not to say a word-the same promise he had made to someone else as well. But of course, you couldn't have known that.
Slowly, you realized how different you two were. You were extremely private- he was all about the public. You valued knowledge and tried your best and therefore you were the ideal type of student. He, to simply put it, didn't give a flying care about academic achievement. He was smart, very smart-just not interested in classes. You were really uncomfortable when someone was flirting with you-he, oh Merlin, he was the absolute flirt. You never let out the sarcastic remarks you wanted because it was rude. He was more cunning than a Slytherin.
You were far too different. Worlds apart. That, however, never stopped your heart from breaking whenever you saw a new mark on his neck or even a girl by his arm. You thought that as the years would pass, you would have managed to stop thinking about him. You have dated couple of guys-much to your brothers' dismay. Remus didn't really like the idea of you dating. Mainly because he knew what the boys were thinking about you. He had seen the way they were looking at you. You were his sister!
You did everything you could to get over him. It was very hard. You knew him better than anyone. When he ran away from his house and went to James, you were the only person to get him to talk, or eat or function like a human being again.
Your heart had a bad, a very bad, habit of loving him. Because you couldn't keep ignoring that word. You loved him. And just like every bad habit, it was so difficult to unlearn him. You had realized that you weren't just in love with him. Being in love with someone, meant to you that you want them to be happy with you. Loving someone... you want them to be happy. And that's all you wanted for him. To finally find happiness.
You had successfully avoided being paired up with him. Until a week ago. McGonagall had assigned you an essay on the Animagus thing-something both of you had mastered years ago.
Naturally, even though you were a bit relaxed, you wanted to get it over with. He on the other hand... not so much. The essay was due tomorrow and you hadn't even started. Your usually loving and shy self was nowhere to be found. You were fuming. You walked in their dorm without knocking. Just barged in.
"Sirius Orion FUCKING Black" you exclaimed, leaving the boys taken aback and terrified. All except Remus. He knew this side of you.
"Okay, folks. Let's leave them to it" James said, dragging a very unwilling Remus and a confused Peter outside and closing the door behind him. You were glaring daggers at him.
"Hello love" he greeted you after a second. He had never seen you mad. Not even when Snape called your-no, wait. He had seen you beat the crap out of him when he called Remus a mistake. He ended up with four broken ribs, a broken leg and almost a broken skull as well. But you were never mad at him. He thought you looked sexy-you didn't know this. Oh, how many things you didn't know... He loved how different you were. Almost too different. But no. You were complemented each other. You were the solace he was looking for-even if he appeared to be louder than a thunder. You were everything he wanted. But you were his friends' sister.
"Hello, my ass". You didn't usually swear but how dare he jeopardize your grades?
Again, he was looking at you like he wanted to devour you. You caught that much. You couldn't have known that he indeed wanted to devour you-in every way possible. He licked his lips unconsciously. You blushed but blamed it on the madness.
"Easy baby. What's wrong?" he asked you nonchalantly. Baby? Baby? Was he for real? You were furious.
You walked over there, one finger pointing him.
"You don't even remember! Of course! Why would you remember me and the fucking essay when you clearly had better things to do? And by things, I mean girls. At least was she worth it?" you yelled at him. With every word that left your mouth, you were getting closer and closer until your pointing finger was poking his chest. He looked bewildered. Like he could never believe you would have actually said those things.
"You look hot" he mumbled. Your eyes grew wide and your breath was caught in the back of your throat.
"What?" you asked flustered.
"What?" he repeated as shocked as you. You took a step back. You were thrown off balance. What had just happened?
"You-you said... I look-I look hot" you said breathlessly. He blushed and lowered his head. He blushed. Sirius Black blushed. Now, you were even more stunned. He realized that it was now or never but he wasn't good with this type of words. He was sure that if he tried to tell you what he wanted- he would end up falling off of the Astronomy Tower. So instead of that, he grabbed your wrist, pulled you close and kissed you feverishly. You froze for just a second before you tangled your fingers into his dark locks, tugging them. You kissed back with equal passion. You have waited for this way too long. He was about to wrap his arms around your waist-but he pulled back, breaking the kiss.
"Listen. I like you. A lot. Like, A LOT. And I know I haven't been the best person and your brother, oh Merlin. Remus will kill me-but I want you, love. Today, tomorrow and as long as you'll have me. I-I am in love with you" he breathed out. Honestly, you couldn't care less about your brother. You cupped his beautiful face.
"I know you, Siri. I know who you are and I've been in love with that person for a while now" you whispered a bit unsure. You were confessing. It's not like you can take it back. This time he did wrap his arms around your middle, roaming your body with his hands, while your hands were already moving down to the hem of his shirt. You weren't that innocent. He chuckled. His lips found their way. Your senses reorient themselves as you felt him cupping your ass, pinning your back against a wall. He settled perfectly in between your thighs and you instinctively wrapped your legs around his waist for leverage. His tongue traced along your bottom lip frantically. A low moan escaped your mouth, something that turned him on. You could feel his member poking your thigh. And that was turning you on. His taste exploded into your mouth as he slipped his tongue in, caressing yours passionately, making you beg for more. His kisses made their way to your neck, biting your soft spot making you whimper. You threw your head back to the wall. This was far more intense than you could have ever expected. Biting, licking, kissing his way down, he moved his lips past your collarbone and to your chest. He tore your shirt open. You slightly gasped, looking at him with a burning sensation building up. There was... lust and passion and Merlin, you wanted more.
"I was afraid to ever make a move, even though I fell for you the first time I saw that gorgeous smile of yours" he husked. He was driving you insane.
"I want you" you breathed out. A beat passed between you two before you practically collided together, your hands buried in his hair, bringing his lips harder against your own. He took you both off of the wall, stumbling through your rough kisses to bring you over to his bed. He broke you away from him so he could lay you down on top of the sheets and soon you felt his warmth against you as he crawled on top of you. His hand brushed your hair from your face as he leaned down to kiss you again, slowly moving his lips over yours this time. You adjusted your body underneath him to be pressed against you, in all of the right places. His broad physique and warm muscles felt so damn good against your body and you did all you could to wrap yourself around him.
Eventually, his lips found their way down to your neck, sucking in all the places he had dreamt of. You had been dreaming of this as well. Too many nights, lying awake, trying to catch your breath when you were thinking about all those things he could do to you. Your thoughts were interrupted as you felt one of his hands making its way up your waist, massaging you as he reached for your breasts. He unclasped your bra within a matter of seconds. You kicked your shoes off and let them fell off the bed, leaving you in your panties and stockings. He stayed hovering above you, soaking in the sight of you laying out and open for him this way.
"We are keeping these" he said with a dominant tone as he pointed your stockings.
He buried his face into your chest, leaving gentle kisses and nips across both of your breasts as his hands grasped your thighs. You opened your legs more and puffed up your chest instinctively, offering yourself completely to him. He brought your legs up around his waist so he could resume grinding his aching cock against you. He took your nipple into his mouth. His lips and teeth gently pulled against it and your hips started to grind harder into his own, the arousal pooling between your legs nearing unbearable. He switched his attention to the other one and used his fingers to pinch and caress the other.
"Sirius, please" you begged but he wasn't about to do anything unless you asked.
"What is it you want, doll?" he teased you.
"Your fingers inside of me" you confessed. Sirius seemed as shocked as you about this sudden confession, but he gave you a smirk in delight.
"Naughty girl" he growled and you felt his fingers sneaking into your panties. He easily slid his fingers inside you, crooking them to rub against your walls. You grasped tightly at his shoulders. He continued to thrust and crook inside, nibbling on your ear as you moaned and clenched around him. Once his fingers were nearly dripping of your excitement, he pulled himself out and away from you, posing above you as he brought his fingers to his lips and licked them clean, moaning at the sweet taste of you.
"Just like candy" he praised you. You felt so unbelievably close, just by his praises.
He finally stripped off his shirt. He was perfectly shaped and he knew it. He tossed it aside and made direct eye contact with you as he took his pants and boxers off. At the sight of his cock, you finally felt inspired on what you wanted to do. How not innocent of you. You didn't give him any chance to take control as you wrapped your hand around his exposed shaft, squeezing it tightly and giving it a slight tug. His mouth opened in a breathless moan and his hips instinctively thrust forward into your hand, seeking more friction against you. You pulled yourself into a crouch at perfect level with his cock, peeking your tongue out to lap at the head. You looked up at him and kept your eyes on him as you continued to run your tongue along the bottom of his shaft, feeling jitters of excitement. You took him deeper into your mouth, hollowing out your cheeks as you began to take him down your throat.
You felt his body began to quiver and he cupped a hand on the back of your head. At his encouragement, you began to take him in deeper, reaching one hand to behind his hips to help him to thrust deeper into your eager mouth. Your other hand went to caress his balls. You would be lying if you claimed you hadn't thought about this.
It had you turned on so much that you were almost ready to reach between your legs to get yourself off before he practically threw you off of him. You stared over at him from your landing spot on the bed, panting and confused.
You reach up to cradle his face in your hands, pulling him down to your lips to kiss him over and over.
Your legs instinctively were wrapped around his waist. You wanted to hold him close to you, to feel him all over you. You needed him to fill you, to be with you, to love you in more ways than just sexually. You needed to offer and have him take your entire body and soul. You weren't just a one-time thing. And he knew it.
"Please, Siri. I want you," you whispered to him between kisses. He kissed you to let you know that he felt the same, sweetly, tenderly as he finally slid himself into you.
"GET OFF OF HER". It would be an understatement to say that you froze. Sirius shielded your body from view using his. Your brother was an asshole.
"That's my sister! Are you insane?! What did you do to her?". Remus was yelling at Sirius, not once looking over at you. Sirius was looking at you utterly shocked. He wanted to apologize. To you. Not to your brother.
"What kind of a friend are you? Sleeping with her? How dare-"
"I love her". That made your head spin. Remus was left without words. Finally.
You cupped his face, ignoring the protests of your brother and kissed him.
"Sorry about that". That was James who was dragging, quite literally, Remus out of the room.
"WHAT THE HELL PRONGS?". You didn't care. You couldn't. All you could think about was Sirius. When you were finally alone, you smiled at him, chuckling a bit.

"Where were we?".
