The library was nearly empty at this hour. Most eighth-years were at dinner or holed up in the common rooms, enjoying their Friday evening freedom. Harry sat in their usual alcove, tucked away in the Restricted Section where Hermione had convinced Madam Pince to grant them research access.
His Charms textbook lay open in front of him, but he wasn't reading it.
Hermione knelt between his legs, her head bobbing steadily as she worked his cock with practiced skill. Her school robes were gone, left in a heap nearby. All she wore was her white button-up shirt, hanging open to expose her bare breasts, and her skirt pushed up around her waist. No knickers. He'd ordered her not to wear them today.
She'd obeyed without question. She always did.
Harry's hand rested in her hair, not guiding, just holding. Grounding. Her warm mouth slid down his length again, taking him deep, and he felt her throat work around him as she swallowed.
"Eyes up," he said quietly.
Hermione's gaze lifted immediately, locking with his. Her eyes were glassy, unfocused with arousal. Her lips were swollen and slick, stretched obscenely around his cock. She looked wrecked already, and he hadn't even properly touched her yet.
Two months. That's how long this had been going on.
It started small. An offhand comment during a study session where he'd told her to stop fidgeting and focus. She'd gone still immediately, her breath catching, and he'd noticed the way her thighs pressed together. The flush creeping up her neck.
He'd tested it again. Simple commands. Fetch his books. Sit here. Be quiet.
Each time, that same reaction. The hitch in her breathing. The way she'd shift in her seat, trying to hide how turned on she was getting.
When he'd finally pushed her against the wall of an empty classroom and asked if she wanted this, wanted him to use her, she'd said yes before he'd even finished the question.
Now she was his. Completely.
Hermione whimpered around his cock, the vibration traveling straight through him. Her hand came up to cup his balls, rolling them gently as her tongue worked the underside of his shaft.
"Good girl," Harry murmured, and he felt her shudder at the praise.
She pulled back slowly, letting him slip from her mouth with a wet sound. A string of saliva connected her lips to his cock, and she licked it away before speaking.
"Please," she whispered, voice hoarse. "Please, I need you."
Harry's fingers tightened in her hair. "You need what?"
"I need you to fuck me. Use me. Please." Her eyes were desperate, pleading. "I've been good, haven't I?"
"You have." He stood, pulling her up with him by her hair. Not rough enough to hurt, but firm enough that she gasped. "Turn around. Hands on the shelf."
Hermione obeyed instantly, presenting herself to him. Her ass was already pink from the spanking he'd given her this morning in his dorm. He'd bent her over his desk before breakfast and painted her skin red while she counted each strike aloud, thanking him after every one.
She'd gone to classes with his handprints still burning on her flesh, sitting gingerly through each lecture, and he knew the discomfort had kept her wet all day.
His hand came down hard on her ass now, and she bit back a moan.
"Quiet," Harry ordered. "We're not alone in here."
It was true. He could hear footsteps a few aisles over. Some younger student looking for a book, probably.
Hermione nodded frantically, pressing her lips together.
Harry smiled.
Harry's hand slid between her thighs, finding her soaked. He dragged two fingers through her folds, circling her clit once before pulling away. Hermione's hips jerked back, chasing the contact.
"Greedy," he said, landing another sharp slap on her ass. "Did I say you could move?"
"No, sir. I'm sorry." Her voice was strained, desperate.
"That's better." He pushed two fingers inside her without warning. She was tight and hot, clenching around the intrusion immediately. "You're dripping, pet. Were you thinking about this all day?"
"Yes," Hermione gasped. "Couldn't stop thinking about it. About you."
Harry pumped his fingers slowly, watching her struggle to stay still. "Tell me what you were thinking about."
Her face flushed darker. "I was thinking about Wednesday night. When you had Daphne in your room."
His fingers stilled. "And?"
"I was thinking about how you looked when I walked in," she continued, her voice breathy. "How you didn't stop. You just kept fucking her while you told me to watch."
Harry's cock throbbed at the memory. Daphne Greengrass sprawled on his bed, her legs over his shoulders as he drove into her. Hermione walking in, freezing in the doorway, her eyes going wide.
He'd looked right at Hermione and said, "Close the door. Sit down. Don't touch yourself."
And she'd obeyed. Sat in his desk chair and watched him finish with Daphne, her thighs pressed together, hands clenched in her lap, practically shaking with need.
Afterward, when Daphne had left, he'd taken Hermione on that same bed, still messy from the other girl, and she'd come so hard she'd screamed into his pillow.
"You liked watching me fuck her," Harry said now, curling his fingers inside Hermione, finding that spot that made her gasp.
"Yes," she whimpered. "God, yes. I liked knowing you could have anyone and you still came back to me. That I'm yours even when you're with someone else."
"You are mine." He pulled his fingers out and brought them to her mouth. "Clean them."
Hermione took his fingers between her lips, sucking them clean, tasting herself. Her tongue worked between them, thorough and eager.
When he pulled his hand away, he reached for his wand and cast a quick contraceptive charm. Then he lined himself up, the head of his cock pressing against her ass.
"Wait," Hermione said quickly, and Harry paused.
"Color?" he asked. Their safeword system. Red for stop, yellow for slow down, green for go.
"Green," she said immediately. "Just… can you…" She trailed off, embarrassed.
"Say it."
"Can you make it hurt?" The words came out in a rush. "Please. I need it to hurt."
Harry's grip tightened on her hips. "You want me to wreck you."
"Yes. Please." She was practically begging now. "Use me. I don't care if it hurts. I want to feel it tomorrow."
Something dark and possessive stirred in his chest. He pressed forward slowly, letting her feel the stretch, the burn of him forcing his way into her tightest hole.
Hermione's breath came in short gasps, her hands white-knuckled on the shelf. "More," she gritted out. "Don't stop."
Harry didn't. He pushed in steadily until he was fully seated, buried to the hilt in her ass. The tight heat was overwhelming, her body gripping him him.
"Fuck," he breathed. "You feel perfect."
He pulled back and slammed in again, hard enough that Hermione had to bite down on her own arm to muffle her cry.
"Remember," Harry said, setting a brutal pace, "we're not alone. If you make too much noise, someone will find us. Find you like this, being used like the desperate little slut you are."
Hermione whimpered, and clenched around him.
Harry's hand slid up Hermione's spine, fingers wrapping around the back of her neck. Not squeezing yet, just holding. A promise.
"You'd like that, wouldn't you?" he said, driving into her harder. "Someone seeing you bent over, taking my cock in your ass. Seeing what a good little whore you are for me."
"Yes," she gasped against her arm, her voice muffled. "God, yes."
His fingers tightened around her throat, cutting off her air. Not completely, just enough. Hermione's whole body went rigid, then melted, surrendering completely to his control.
He counted silently. Five seconds. Then released.
Hermione sucked in a ragged breath, and he felt her pussy clench, empty and dripping. She was close already, he could tell by the trembling in her thighs, the way her back arched deeper.
"Don't you dare come," Harry ordered, punctuating the words with a particularly brutal thrust. "Not until I say."
A strangled sound escaped her throat. Protest and need all tangled together.
Harry's free hand cracked across her ass, hard enough to echo in the quiet library. Hermione jerked forward, barely catching herself on the shelf. A book tumbled to the floor with a thud.
They both froze.
Footsteps. Closer now. Someone was definitely nearby, just a few rows of shelves away.
"Stay quiet," Harry breathed in her ear, not slowing his pace. If anything, he fucked her harder, the obscene slap of skin on skin filling the small space between the bookshelves.
Hermione bit down hard on her lip, eyes squeezed shut, tears leaking from the corners. She was trying so hard to be good, to stay silent, to not come without permission.
Harry's hand found her throat again. This time when he squeezed, he reached around with his other hand and found her clit.
Hermione's eyes flew open, panicked and pleading. She shook her head frantically.
"I didn't say you could come," Harry reminded her, his fingers working her clit in tight circles even as he choked her. "But I didn't say you could breathe either."
Her body convulsed, caught between too many sensations. The burning stretch of his cock in her ass. The pressure on her throat. The merciless rhythm on her clit. The footsteps still too close. The desperate need to stay silent.
He let her breathe.
"Please," she sobbed quietly. "Please, I can't… I'm going to…"
"No, you're not." He slapped her ass again, then grabbed a fistful of her hair, yanking her head back. "You're going to be good. You're going to take everything I give you and you're not going to come until I'm finished with you."
"I'm trying," Hermione whimpered. "I'm trying so hard."
"I know you are." His voice softened just slightly, even as his hips maintained their punishing rhythm. "You're doing so well, pet. Taking my cock so perfectly. Making me feel so good."
The praise mixed with the degradation, the pain mixed with pleasure, and Hermione was shaking, teetering on the edge but holding back through sheer willpower.
Harry felt his own release building, his balls tightening. He was close.
"When I come," he said, his voice rough, "you're going to come with me. Not before. Understand?"
"Yes, sir," Hermione gasped. "Please. Please, I need it."
His hand tightened on her throat again as he pounded into her, chasing his release. The angle was perfect, the tight heat of her ass gripping him exactly right.
"Now," Harry growled, his fingers finding her clit again. "Come for me now."
Hermione's scream was silent, her mouth open but no sound coming out as her throat was constricted. Her whole body seized, clenching around him rhythmically, and Harry buried himself deep and came hard, spilling inside her.
He held her throat for another second, then released.
The sound she made was broken and wrecked and absolutely perfect.
Harry pulled out slowly, careful now. Hermione whimpered at the loss, her legs trembling so badly she could barely stand. He caught her before she could collapse, gathering her against his chest.
"I've got you," he murmured, lowering them both to the floor. He settled with his back against the bookshelf, Hermione cradled in his lap. "You're okay. You did so well."
She was shaking, her breathing still uneven, tears streaming down her face. Not from pain. From the overwhelming intensity of it all, the release of everything she'd been holding back.
Harry held her close, one hand stroking her hair, the other rubbing soothing circles on her back. "Breathe with me, pet. In and out. That's it."
Hermione buried her face against his neck, her arms wrapping tight around him. Slowly, her breathing steadied, matching his.
"There you go," Harry said softly. "Good girl. You were perfect."
A broken sound escaped her, half-laugh, half-sob. "I love you," she whispered against his skin.
"I love you too." He kissed the top of her head, still holding her. "So much."
They stayed like that for a while, tangled together on the library floor. Harry reached for his wand and cast a quick cleaning charm on both of them, then summoned Hermione's discarded robes.
She made a small noise of protest when he tried to shift her off his lap.
"Just getting you dressed," he assured her. "Not going anywhere."
Harry helped her into her clothes, his touches gentle now. When she was decent, he pulled her back against him, letting her rest her head on his shoulder.
"How do you feel?" he asked.
Hermione was quiet for a moment, considering. "Floaty," she finally said. "Good. Really good."
"Any pain I need to know about?"
"My throat's a little sore. And my ass." A small smile curved her lips. "But that's what I asked for."
"It is." Harry tilted her chin up, checking her neck. There were faint red marks where his fingers had been, but nothing that wouldn't fade by morning. "I wasn't too rough?"
"No." Hermione's eyes were clear now, focused. "It was exactly what I needed. What we both needed."
It was true. Harry had been wound tight all week, stress from N.E.W.T. preparation and the lingering weight of everything that had happened during the war. This, having Hermione submit to him so completely, trusting him with her body and pleasure and pain… it quieted something restless in him.
Made him feel grounded. In control.
"Thank you," he said quietly.
Hermione kissed him, soft and sweet. "Always."
She shifted in his lap, and he felt her wince slightly.
"Come on," Harry said, helping her to her feet. "Let's get you back to my room. I'll run you a bath."
"Mmm, that sounds perfect." She leaned heavily on him as they gathered their things. Her legs were still shaky, and there was a slight hitch in her step.
Harry steadied her, one arm around her waist. "You're going to feel this tomorrow."
"Good," Hermione said, a satisfied smile on her face. "I want to feel it. Want to remember."
They made their way out of the library, moving slowly. Hermione's hand found his, their fingers lacing together.
"Next time," she said as they walked, "maybe you could invite Daphne again. I liked watching."
Harry glanced at her, eyebrow raised. "Yeah?"
"Yeah." Her smile turned wicked. "Maybe next time I could join in. If you wanted."
Harry's stomach tightened at the thought. "We can talk about that," he said, his voice rough. "After you've recovered."
Hermione laughed, the sound bright and happy, and leaned into him.
They had all the time in the world to explore what they wanted.
Together.
