At 10 p.m. on September 18th, Hermione slipped Harry's invisibility cloak over her head and made her way out of her dormitory and across the common room, where she then stepped through the portrait hole and out into the corridor.
At 10:12 p.m, she paced in front of the tapestry three times as she asked the room of requirement to grant her passage to Hogsmeade.
Once she stepped through the passage to the tunnel, hidden behind a portrait of a young witch, the path was quicker than she thought, and by 10:20 she had made her way out of the cellar of Honeydukes and into the alleyway between the candy shoppe and the bookstore.
She paused for a few minutes to catch her breath, and at 10:30 p.m. on the dot, she apparated away from Hogsmeade and landed in a park in Islington, down the road from 12 Grimmauld Place, where she sat on a picnic table, using the light of her wand to read Hogwarts: A history until 11:45 p.m.
At the stroke of midnight, she raised her fist and knocked on the door of the ancestral home of the House of Black, where the reason for her late-night excursion now resided with his best friend.
At 12:01, a shirtless, half-sloshed Sirius Black opened the door. He raised an eyebrow, his mouth dropping open in surprise, but she held her hand up and shook her head, effectively cutting him off before he could speak.
"Where is he?" She whispered, as quietly as possible without being inaudible to human ears.
"I told him you'd know." Sirius shook his head and took a swig from the whiskey tumbler in his hand then stepped aside, nodding toward the stairs. "He’s up in the library. Just... tread softly, Kitten."
"Fuck that." Hermione brushed past him, bounding up the stairs two at a time, and darted down the hallway. She reached the door to the library and wrenched the knob, shoving the door open with her shoulder as she barreled through, then immediately skidded to a stop to avoid running head first into Remus Lupin.
"Hermione." He said her name like a prayer, low and rattling, and she felt every hair on her body stand on end as his eyes flashed gold.
"It's my birthday." She said softly, taking a step closer. Remus took a step back, and she continued on until the backs of his legs hit one of the wide tables nestled just between two of the stacks.
“Yes.” He dipped his chin and gave her a soft smile, though it fell flat given the tightness around his eyes. “Happy birthday, Hermione.”
“It’s my eighteenth birthday, Remus.”
"You know." Remus leaned back against the table as he reached a shaky hand out, cupping her face. Hermione gave a soft nod in response as she leaned into his touch. "Of course, you know. You sweet, clever girl. But Hermione, I'm... you're..."
"I’m yours." She cut him off, placing her hand over his where it lay on her cheek. "I waited. I was good. For five years, Remus. But it's my birthday now."
"We can't." His voice cracked as he gripped the table beneath him with his free hand. "It's too... I won't be able to let you go, Cariad. You still need to finish school, to live a life, I'm -"
"I handled it." Hermione dug in her pocket, pulling out the letter from Professor McGonagall, and shoved it in his hands. "I have the marks to test out early. I sit for my owls on Monday. I could have gone tomorrow but I figured... This might take some time. We’ll need a few days to...I've already lived so much. So much, Remus, but the entire time it's been for this. Because I've known, since I opened the second book in the stack of materials about Werewolves that I pulled from the Hogwarts library to study for the essay Snape gave us in my third year. And even before that, that day on the train... I knew. It just took a bit of time to find the words."
"You called for me." Remus said softly, his voice nearly dreamy in its reverence. "That night, after the shack."
"I did. That's when I was sure. They say the wolf only responds to the call of its own kind. Or of its..." Hermione swallowed roughly, but Remus finished for her as his hand slid from her jaw to her neck.
"Mate." His nostrils flared and his eyes flashed gold, his fingers digging into her neck and shoulder almost painfully, but Hermione relished the touch, had craved it for so long, needed it so badly she could hardly think straight.
"I'll bite you. Right here." He tightened his hold on her neck again as he spoke in a low, growling tone. "You'll bear my mark forever. And here."
He placed his other hand on her stomach and Hermione let out a low, soft whine.
"I'll fill you so full. Werewolves are exceptionally fertile, Hermione, and with our mates, we don't miss. Is that what you want? To be marked by an old man? To carry my pups in this tight little body? To bind yourself to a beast for the rest of your life?"
"Yes." She said, simply. "Did you... did you know it hurts? Every time I'm around you, it hurts. Right here." She placed a hand over his on her stomach. "I'm so empty. I don't care about anything else, Remus. I just need you."
"I can't give you a life, Hermione. I can't even get a job, and you - you deserve the world."
"So do you. And I'll get it for us. I'm going to change the laws my damn self, Remus. I've already spoken to Kingsley, and I start in the magical creatures department next fall. I asked for a year, so we have time." She emphasized her unspoken point by pressing her hand more firmly against his on her lower stomach. "I have a trust fund, and the money from selling my parents’ house. Muggle comfortability is rich in this world. And even aside from all of that, I don't care about money or power. I just want you."
"You've thought of everything." Remus chuckled, sliding his hand from her stomach to the small of her back as he straightened, towering over her.
"Yes, well, you should have known I would." Hermione sniffed as she looked up. Given their height difference - he was well over a foot taller than her - she had to crane her neck to meet his eyes.
"Cariad.” He whispered with a small shake of his head. “You sweet, beautiful girl. You've no idea... you have to go. If there is any part of you that isn't sure about this, you have to leave, now. You've got me hanging by a thread here."
"So let it break." Hermione’s voice was firm, despite the slight shake in her tone as his thumb began to stroke slow circles on her back. "I'm yours, Remus. Let go. Take what's yours."
"Fuck." He rasped, crushing her against his chest as his hand moved back to her chin, tilting her head back. He leaned in, his breath ghosting over her lips as they locked eyes.
"I'll hurt you. I won't be gentle. You're so fucking tiny, little one."
"And I'm yours. I'm made to take it."
"Mine." Remus crashed his mouth to hers, forcefully prying her lips apart with his tongue as he attacked, nipping at her lips, his fingers digging into her jaw. Hermione whimpered, then moaned into his mouth, and whatever thin bit of resolve he had left seemed to break in an instant.
He pulled back with a growl and reached down, digging his hands into her arse and palming the flesh roughly before he moved to her hips. He spun her around, stepping in behind her as one hand fisted in her hair and pressed her chest to the table. Hermione sucked in a breath, arching her back as Remus clumsily fumbled with the waistband of her skirt before he gave up and flipped it up over her arse.
"Fucking Christ. This hungry little cunt is already weeping for me, isn't it?" He marveled, running a finger over her sodden knickers before he murmured something too low for her to hear. Hermione gasped as the cold air hit her when her knickers vanished, then nodded, the side of her face sliding against the wood of the table beneath her.
"Mmhmm. I've been soaked for you for years."
"I fucking know. Gods, the amount of times I've almost thrown you down in front of the entire Order. Such a little fucking tease, sitting across from me with your little cunt dripping onto the seat. You make me fucking... Do you have any idea, Hermione? Did you know what you were doing?" He stroked a finger between her slick folds, then plunged inside without preamble, and she yelped, then nodded again.
"Of course you did. Needy little fucking slut. Did you know I'd wait until everyone left and sink to my knees in front of whatever chair you'd been in, smelling the scent of your cunt while I fucked my hand? Licking the fucking wood, desperate for a taste of you?"
"I'd hoped." Hermione admitted. “Sometimes, I’d slip my knickers off and sit down to dinner bare underneath my skirt, so there was nothing in the way. Wanted you to smell what it did to me, to even be in the same room as you."
“Merlin, witch, you're trying to kill me.” Remus muttered. He twisted the finger that had been resting inside of her and began to stroke her inner walls, pumping slightly as he ground his palm against her clit.
“No.” Hermione moaned. “I was just trying to make you… take me.”
“Impatient girl.” He tutted his tongue and stilled his hand. “You liked torturing me, didn't you? Turning me into a needy fucking wreck. Dirty old man catching splinters on his tongue while I stroked my cock to the scent of this tight little teenage cunt?”
“Yes.” Hermione admitted, rocking her hips back in a desperate attempt to make him move. “Remus, please.”
He withdrew his hand, and she moaned in protest, moving to sit up, but he pressed his hand between her shoulder blades, pinning her down as he kicked her legs wider apart. She heard the clank of his belt buckle and felt herself grow even wetter, and then finally - mercifully - he stepped forward, fisting his cock in his hand as he began to tease her, sliding the thick head against her clit.
“Oh my gods, Remus, please. Please, I can't wait. I need you.”
“I love the way you say my name.” He growled, wrapping a hand around her hip. “But that's not what you call me, is it?”
Hermione stilled, her mouth falling open in a silent gasp. Surely he didn't know… she'd used silencing charms, hadn't she?
“Silencing charms work well for human ears, Cariad, but I'm a little… heightened. I heard everything. Every time you thought you were being slick, sliding your little hand into your knickers when you'd stay here in the summers.” He notched his cock against her entrance, and her breath caught in anticipation, but he stayed perfectly still, taunting her. Were she capable of human thought, there might have been something to be said for his ability to restrain himself, but all she could think was move and please, Remus, and fucking fuck me.
“Oh, I will.” He laughed, causing her to realize she must have been babbling her thoughts aloud in the haze of her mindless need. “But that’s not what you call me, is it, little one? Tell me what you scream when you fall apart on your hand, dreaming of my cock, Hermione, and I’ll give you what you need.”
“I - I, um…” She blushed, squeezing her eyes shut, and she felt a sharp tug on her hair as he wrenched her head up off of the table, his weight pressing against her back as he leaned in, looking her in the eye.
“None of that, Cariad. Tell me what you are. Say it.”
“Yours.” Hermione whimpered as he moved, just slightly, the very tip of his cock pressing inside of her. “Your mate.”
“Good girl.” He darted his tongue out to lick her lips as he pressed forward, just barely. “My mate. Mine. You don’t close your eyes and go all shy. Not with me. Never hide from me. Tell me you understand.”
“I understand.” She bit her lip, her brows pinching together as she rocked her hips back, gasping at the sensation of the thick ridge below the head of his cock catching on her hymen.
“Oh, look at that. You saved it all just for me, didn’t you, Cariad?” He crooned, his eyes burning molten gold as he held her gaze.
“Mmhmm. Never even been touched. Kissed. Only ever wanted you. It’s always been yours.” She rambled.
“Whose is it?” He thrust forward, just barely, and she could feel herself straining against the intrusion of him, the mere inch or two of his cock buried inside of her already stretching her beyond comprehension. She opened her mouth to respond, but could only manage a soft whine.
“Come on, baby. You’re doing so good for me.” He ran a hand down her side and rubbed her hip soothingly. “Tell me. It’s just us. You want to know why I was able to hear you, all those nights? Because I had my ear pressed to the wall from the next room, my hand wrapped around my cock, waiting for that perfect fucking word to tumble from your mouth when you came. Tell me whose cunt this is, little girl. It’s just us.”
“Yours, Remus.” She whimpered, shame burning across her skin.
“Come on,” he repeated, releasing his hold on her hair to straighten behind her. He grasped her hips in both hands, slowly rocking back and forth but never sinking farther and gods, she felt like she was about to fall apart already. “Tell me who I am, Cariad. Let me hear you say it.”
Hermione bit down on the inside of her cheek - gods, it was so hot, that he’d heard her, that he’d touched himself to the sound of her doing the same, but to know he’d heard her say that, that little slip that always seemed to work its way out of its own volition every time she came picturing his scarred face, his big hands and broad shoulders - it was wrong, so fucking wrong, even as it seemed to flow so naturally when she was alone and thinking of him.
“Please.” She mewled, rocking her hips again.
“Please, what?” He gripped her hips harder, stilling her movements. “You have no idea how many times I’ve imagined having you, right here in this library, just like this, and hearing you say it. Come on, Cariad. Tell me who I am. Beg for it properly, and I’ll give you what you need. Give you everything.”
He punctuated his words with a sharp thrust, and she gasped, tears springing to her eyes as she felt a swift, sharp pain. It ebbed as quickly as it had flowed, though, and she could feel him so deep, now seated at least halfway inside of her. It was intoxicating, pain and pleasure all at once, rapturous and too much and still not enough. She needed to feel all of him, needed -
“More. Please, Daddy.”
“Oh, fuck yes.” He hissed out through gritted teeth as he jerked back on her hips, slamming himself to the hilt inside of her. Hermione screamed, her face falling back to the table. She pressed her cheek to the cool wood, her eyes rolling back at the torturously perfect feel of being fully impaled on his cock.
“Good girl.” He praised, running a hand up underneath the hem of her shirt, his fingers slowly stroking her spine. “Such a perfect little mate. Breathe, baby. Daddy will take care of you. Does it hurt?”
“Yes.” Hermione whined. “Hurts, Daddy. I’m so… fuck, so full.”
“Oh, you poor thing.” He cooed. “Just stay still, okay? Let Daddy help you through it.”
“I need… move, please, please, Daddy.”
“Not yet. You’re going to stay just like this and warm my cock until you’ve adjusted, Cariad.” He commanded, his hands still running across the skin of her back, her hip, everywhere he could reach as he comforted her through the pain of the intrusion. “I want you to take a deep breath and clench your muscles around me - perfect, perfect, baby girl, just like that. You’re being so good, listening to Daddy so well. Now relax, and then do it again.”
Hermione did as she was told, tightening and releasing around his thick cock. After her fourth or fifth round of kegels he pulled back just slightly and then thrusting deeper inside of her, drawing a low, guttural moan from her chest.
“There you go, Cariad. How’s that feel?”
“Better, Daddy. I need more.”
“Good girl. You’re doing so well, telling me what you need.” Remus leaned forward, burying his face in her neck, drawing in audible breaths as he began to move, making shallow thrusts into her heat. “You feel so good wrapped around Daddy’s cock. I need — I’m going to move you now. Trust me, yeah?”
“Yes. Anything.” Hermione panted out. He stood back up, pulling her with him until her back hit his chest, and banded an arm beneath her thighs as he wrapped the other around her waist, folding her in on herself. She let out a surprised yelp and he chuckled as he took a step back from the table then began to walk - to fucking carry her across the room, as if she weighed nothing, his cock still firmly seated inside of her in a display of raw strength that sent a jolt of electricity straight to her core.
She’d never been more turned on in her life. She could feel her cunt practically weeping around his cock as he settled into an armchair, then grabbed her hips and turned her, swiveling her on top of him as if it were nothing, until she was straddling him.
“Hi.” She giggled as they came face to face - awkwardly, she knew, but really, what does one say to the guy who just took your virginity over a table and then relocated you via cock-transportation? “I’m your mate, Daddy.”
“Yeah.” Remus laughed, shaking his head. “Yes, you are. My mate. And you’re so lovely. Daddy’s baby girl.” He reached a hand up, running this thumb over her lip, then pushed it inside as his free hand fell back to her hip and pulled her toward him, rocking her in his lap. Hermione pinched her brows together, moaning softly, and he smiled, a predatory sort of grin.
“You’re gonna be such a good girl for Daddy, aren’t you, Cariad?” He released her hip and waved his hand, vanishing her shirt and bra in one fell swoop, leaving her clad only in the school skirt that he’d rucked up over her hips.
“I’ll be a good girl for you, Daddy.” She whispered, the words coming out garbled around his thumb as he pressed down, opening her mouth wider.
“Good girl.” He rewarded her with a deep, punishing thrust, then used his hold on her mouth to push her back so she sat straighter in his lap. “Daddy’s going to fuck you, now, babygirl. I need…fuck, I need to rut you. My sweet little mate. It’s going to hurt, but you’re going to take it so well, won’t you?”
“Yes, Daddy.” Hermione moaned.
“Later.” He whispered, releasing her mouth and running his hand down to her chest, palming her breast roughly. “Later, I’ll take it slow. Run you a bath and take such good care of you. Right now, you’re gonna scream for Daddy. And then I’m going to sink my teeth into your neck and make you mine.”
“Please.” She whined desperately, rocking in his lap in a pitiful attempt to take him deeper, grinding her clit against his pelvis as she sought friction. “Please, Daddy, I can’t take it. I need you to move.”
“Such a brave little girl.” He laughed darkly, then leaned in and captured her lips, kissing her roughly as he pulled her against his chest. He broke the kiss and buried his face in her neck once more, drawing in stuttered breaths as he began to move, setting a punishing pace.
“You smell so fucking good.” He rasped. “Like lemons and sugar, and something flowery, like fucking springtime. So fucking mine.”
“Yours, Remus. Daddy, I - fuck,” She moaned, throwing her head back as he fucked her harder, using his hold on her hip to slam her down into his lap with every thrust.
“Gonna knot this tight little cunt. Keep you trapped on my fucking cock while I breed you.” His words hit Hermione like an oath, wrapping around some part of her being she couldn’t quite name and she felt herself clench around him as he continued to move inside of her, driving her closer to the precipice of her ruin with every slam against her cervix.
“Oh, Daddy’s girl likes that.” He cooed mockingly, scraping his teeth over her neck. Hermione screamed, then nodded, her breaths coming in short, shallow gasps.
“Please. Please, I - oh my gods, I can feel it.” She was coming undone, sinking deeper into the haze of lust as he continued to fuck her with wild abandon, stretching her farther every time he sunk back inside of her as his knot began to swell. It was a maddening, dizzying feeling, every hard thrust of his cock causing his knot to drag against her g-spot.
She gritted her teeth, trying to hold on, to prolong the sensation as her body began to tremble in his arms.
“Let go.” He whispered, teasing the juncture of her shoulder with his teeth once more. “Cum on Daddy’s knot, baby girl. Let me have it. I’ve got you.”
His words sent her over the edge as she screamed again, a prolonged, breathy Daddy tearing from her throat. Her cunt clamped down on his cock, tightening and then releasing in rapid, fluttering movements as she came harder than she’d ever managed by her own hand, her release squirting out of her and soaking his stomach and thighs.
“Oh, look at you. Drenching Daddy’s lap with this messy little cunt. Such a good fucking girl for me. Tell Daddy what good girls get, little one.”
“Re-rewarded.” Hermione’s lip trembled, her heart leaping to her throat. “Bred.”
“Fuck, yes. Daddy’s gonna knot inside of you, breed this tight little cunt so deep. Gonna keep you stuck on my cock until you’re swollen with my pups. I can’t - fuck,” His movements slowed to a near stop, his knot locking them together as he came with a deep, feral growl before he struck, sinking his teeth into her neck.
Hermione screamed again, the feel of him tearing through her skin as he throbbed inside of her sending her soaring into oblivion once more. She came even harder, her entire body shaking as he groaned against her throat.
She could feel him everywhere. Buried inside of her, his cock twitching with the final spurts of his release, his knot stretching her cunt so wide she felt as if she may split in half, everything was him, coursing through her veins as a peace unlike any she’d ever known settled over her like a tidal wave.
He released her neck, uttering praises of good girl as he alternated between lapping softly at her wounded skin and telling her how well she’d done. She collapsed against his chest and he brought a hand up to trace the ridges of her spine as they settled into a comfortable silence, their chests heaving against each other as they came down from their shared, exhilarating high.
It was everything. He was everything, and she belonged to him, had always belonged to him, but now it was different. Something inside of her settled, some empty ache she’d never been fully aware of until his teeth had pierced her skin, and she sighed in contentment as he pressed his lips to her temple.
“Mine.” He whispered reverently.
“Yours, Daddy.”
