So, I wanted to do this story for a long time. I'd love to have my own OC in with the Marauders, so here it is. Enjoy, and anything you recognise I do not own.
"Black! I swear I'm going to kill you!" I screech, running down the stairs as fast as I could, grateful for all of the Quidditch training I've had, in order to remain the best Seeker. Once again, Sirius had stolen my clothes and towel whilst showering, leaving me with only my tight fitting leggings and beaten, old boots. I reach the bottom step, clenching my teeth as I look at Black's smug face as he stares me out, looking at me up and down. "I had to wear James' bloody shirt. Thanks." I bite out, shoving past him to get to the kitchen. True to my word, I had snuck into James' room and stolen his Quidditch shirt, the red, over sized over worn sweaty shirt feeling rather comfortable against my skin. I kissed James on his forehead before I left, giggling slightly at him as he looked oddly content as my lips pressed against his skin.
"You look good in it, though, my dear Lynch." I can tell he's smirking, the bloody self-centered jerk. I turn around and stick my tongue out at him, and he gives some form of a genuine smile, but falters as soon as we hear footsteps coming down the stairs.
"Where's James?" I hear a soft, tired voice call from behind me. Turning around, I come face to face with Remus, and I smile at him as he smiles back at me, his messy blonde hair falling in front of his eyes.
"He was in bed when I stole his shirt. Probably dreaming of Lily." Remus laughs and places his hand on my hip as he leans forwards for a piece of chocolate he had left open on the counter last night, and I can't stop the mad blush that creeps onto my cheeks, and the butterflies attacking my stomach. At some point since the contact with Remus' hand on my hip, I had stopped pouring my tea into my mug, and Black had crept up behind me as soon as Remus had let go, and wrapped his arms around my waist. I freeze straight away, and unconsciously reach for my wand, only to realise Black probably has it since he stole my clothes. I feel his breath against my ear and neck, and cold rolls down my spine.
"Now, what was that blush for, Lynchie?" He says, jealousy clearing flooding through his voice. He bites at my ear, making me bite down hard on my lip so I didn't scream.
"Get off, Black, and give me my bloody wand!" I screech, elbowing him in the ribs so he'd let go. He steps back, holding his arms out in surrender, and flashes me a quick grin as we stare at each other, and I refuse to look away first.
"So when are you two going to be an item?" James says, grinning through his words. From the corner of my eye, I see Remus quietly sitting on one of the bar stools, just watching. I swallow hard.
"Same time you and Lily become an item." I snap back, crossing my arms over my chest.
"Now now, sister. You know Padfoot will hold you against that." I shake my head, smiling slightly at James, and uncross my arms from my chest and turn away from Black's warm, hopeful gaze to look at James. His messy, ruffled black hair sticking up all over, his warm brown eyes meeting mine.
"One, I'm not your sister, two, I doubt you and Lily will get together, she loathes you as much as I loathe Black," I say, jerking my thumb in the direction of him, "And three, I beat him in everything. He can't hold much against me." I finish with a satisfied grin.
"Well, you may be better than me at everything, but I do still have your wand and clothes..." His voice trails off as Sirius pushes me to the side as he runs past me and James, running to the back door leading to the Potters' garden. Which is basically a collection of massive fields. It's our seventh year, and we're off on Christmas holidays. I was now living with James Potter and his family whilst not at Hogwarts, as my parents are dead and I have no idea who anyone else is in relation to me. I didn't even know my parents, I only knew of them by what Professor's at Hogwarts had told me. James had told his parents about my situation and they gladly accepted me into their home, as me and James were as inseperatable as him and Sirius are. Sirius had been pretty much adopted by the Potter's, as he finally left his hellish family behind, and was then blasted from the Black family tree. Not like Sirius really cared. So, here I am, with the famous James Potter, Sirius Black and Remus Lupin, three quarters of the Marauders, as Peter Pettigrew liked spending time with his family and never came over to James' house as we did. My holidays have never been quite the same since becoming so close the the Marauders, and I loved every second I spent with them. Even that bloody Sirius, who I loathed. I'd rather die than admit I do still rather enjoy his company, though. Everyone would tease me, saying how Sirius loved me, and I'd deny it every time. All I saw when I looked at him was his rather protective gaze and his flirtatious, lopsided grin.
"BLACK!" I scream at the top of my lungs, running after him, pushing poor James out of the way just as Sirius had just done. I chase him around the fields, running down towards the forest. He's done this pretty much every day since he had arrived at the Potter home. He turns suddenly when we're about half way into the dense forest, grinning at me and throwing me my wand.
"Heads up, Marcie!" My eyes widen as he calls me by my first name, my nickname, and I feel my wand pulse under my finger tips as I catch it, and send Sirius a wicked grin and I throw hex after hex at him. He dodges some but is hit rather badly at others, and eventually falls to the floor in surrender as I laugh, brushing off an incoming hex he'd just thrown.
"Come on Siri, you know I'm better at dueling than you are." I say, laughing as I run up to him and offer him my hand. He just stares at me for a while, and I slump my shoulders and my hand falls back to my side.
"Siri?" He repeats, putting himself into a sitting position. I nod my head, and raise my eyebrow.
"You called me Marcie." His eyes widen and a blush fills his cheeks. He. Blushed. Sirius Black, blushed. At me.
"I - I - I did?" He stutters, standing up and never looking away from my amusement-filled eyes.
"Yes. Now come on, James wanted to have a game of Quidditch this afternoon."
I watch her as she leaps off her broom, the gem firmly held in her hands. She laughs as Remus bends down and whispers something in her ear, and jealousy stabs me in the gut. She runs over to me just as me and James land, and she grabs my hand, pulling my fingers out from my palm, and puts the rhinestone gem in my hand, grinning at me. "Told you I'd be able to catch it."
"But it's tiny! And James was firing that thing around like a mad man!" Amusement glitters in her eyes, her beautiful, soft, green eyes-
"You're staring." James whispers in my ear, making me jump and drop my hand back to my side, still holding the gem tightly.
"So, I win the bet. You have to make me and Remus chocolate cake." Marceline says proudly, crossing her arms over her chest and smirking, a strand of her perfectly straight dirt-blonde hair falling to her face.
"You can't make Padfoot do anything!" I yell, running off down to the forest, smiling as I hear her frustrated scream of my last name, and her footsteps following me.
"Padfoot, you're in deep, mate." I turn on my stomach and growl into my pillow.
"I know. But she's so bloody perfect." I groan as James kicks me in the rib, and shakes his head.
"That's my best friend you're talking about, remember?" he says, laughing as he takes off his glasses and lays down on his bed.
"And mine." Remus says, suddenly paying attention to our midnight chat me and Prongs always share.
"Shut it, Moony. You've been all over her lately." I say bitterly.
"You should get her a Christmas present, Padfoot. Start to show her you really care, and you don't loathe her as she loathes you." James says, quickly changing the subject from the incoming argument between me and Remus.
"But how am I supposed to get her something she'll really like? She's perfect, so the present will have to be too." I groan and turn onto my back, suddenly wide awake with ideas running through my head. Our bedroom door suddenly opens and reveals Marceline stood in the doorway, tears tracking down her cheeks. James and I jump up from our beds quickly, panic rising in my stomach and heart. I'd never seen or heard of her cry, even at her parents death. James runs up to her, enveloping her in a tight hug, to which she returns and sobs into his chest. He murmurs things to her and she grunts slightly in response, and when she lets go of him, she grabs his hand and they walk to his bed, Marcie sitting down heavily, crossing her legs in the middle of his bed and wiping viciously at her cheeks. I sit down next to her with a frown etched onto my face, and she slowly turns to look at me, her face a light shade of pink, from the crying and the vicious rubbing on her cheeks. Prongs sits down on the other side of her, and Remus gets up and sits behind us all, and rubs circles on her back comfortingly. I take her hand in mine, not really caring about keeping up appearances and acting so coldly to her. To my surprise, she doesn't pull away, she just entwines her fingers together with mine, a wave of pure happiness and longing taking over my body. Me. Sirius Black, feeling this stupid and happy over a girl. She leans her head on James' shoulder, and for a while nobody speaks, only her heavy breathing to be heard as she fought away the last of her tears.
"I had a nightmare." She says suddenly, making me hold tighter on her hand and Remus' hand to still on her back. He composes himself and continues, making Marcie sigh lightly.
"Want to tell us about it?" James asks softly, placing his hand on her knee. She shakes her head quickly, her eyes widening in panic. Another while passes in silence, as none of us know what to say. It was so un-Marcie like to be in such a state, it even shocked me.
"Can I stay here tonight?" She whispers, looking down at mine and her joined hands.
"Yeah, but you're sleeping in my bed with me. I don't trust Sirius or Remus with you." James says, and Marcie laughs softly. She murmurs an okay, and looks at me, her green eyes searching mine.
"Uhm, Siri, can you let go?" She whispers as I feel heat rise to my cheeks, and I lean forwards and kiss her temple, letting go reluctantly of her hand. I reach my bed and turn on my side, watching her as she gets in James' bed with him, and James wraps very protective, brotherly arms around her. She smiles as she looks over at me, and mouths a goodnight, closing her eyes. I watch her and James, wishing over and over again that I was him, just so I know what it feels like to have her wrapped in my arms out of her choice, not just because I creep up on her and tackle her from behind. I remember the feeling of panic as she ran into our room crying, and that's when I realise I really have fallen hard for her. And that's when it comes to me - the perfect thing to get her for Christmas.
