The green light from the enchanted windows cast everything in an eerie, underwater glow, shadows dancing across the stone walls as Daphne Greengrass ground herself shamelessly against Harry's lap, her hips rolling in slow, deliberate circles that made his cock throb with every movement.
How the fuck did I end up here?
Harry's hands roamed over her body, still clothed but barely, her shirt unbuttoned enough that he could slip his fingers beneath the fabric and feel the warm silk of her skin. His Invisibility Cloak lay draped over the arm of the sofa, discarded the moment Daphne had pulled him down onto the plush green cushions and climbed into his lap like she belonged there.
Which, Harry was starting to realise, she absolutely did.
"You're insane," Harry breathed against her neck, his lips brushing the sensitive spot just below her ear. "Anyone could walk down those stairs."
"I know," Daphne whispered back, and the tremor in her voice wasn't fear. Her blue eyes were bright with excitement, gleaming in the dim green light as she pressed herself harder against his straining erection. "That's what makes it so thrilling."
The Slytherin Common Room stretched out around them, dark and silent, the leather sofas and carved serpents barely visible in the low light. The fire had burned down to embers in the massive hearth, its dying orange glow mixing with the green from the enchanted windows, painting the ancient stone in shifting, writhing shadows. It was well past midnight, the castle silent save for the distant groaning of settling stones, and every dormitory door remained firmly closed at the top of the spiral staircases on either side of the room.
But they could open at any moment.
This witch is going to be the death of me.
Harry's hands found Daphne's arse through her skirt, squeezing the firm flesh, pulling her more firmly against his cock. She mewled at the contact, actually mewled, the sound high and needy in a way that made his blood run hot. This was the same witch who'd tormented him for seven years with her superior smirks and cutting remarks, the same Ice Queen who'd never let anyone see beneath her perfect facade.
And now she was grinding on his cock in the middle of her own common room, whimpering like she'd die if he stopped touching her.
"Please," Daphne gasped, her hips picking up speed. "Please, Harry, I need..."
"Need what?" Harry's fingers dug into her arse cheeks, hard enough to leave marks, and Daphne's whole body shuddered.
"Need you to use me," she breathed, and the words sent a jolt straight to Harry's cock. "Need you to fuck me. Need your fat cock inside me. Please, please, I've been thinking about it all day, I couldn't concentrate in class, I kept remembering the bath, remembering how you filled me up, I need it again, I need it now."
Fuck.
Harry had known, intellectually, that something had shifted between them. The competitive edge was still there, would probably always be there, but underneath it was something rawer now, something desperate and hungry that neither of them could control. But hearing her beg like this, feeling her squirm in his lap, watching the flush spread across her pale cheeks in the dim green light... it was almost too much.
His hands slid up from her arse, over the curve of her waist, up her sides until his thumbs brushed the undersides of her tits through her shirt. Daphne whimpered, arching into his touch, and Harry could feel her nipples already hard and straining against the thin fabric.
"You've become such a slut for my cock," Harry murmured, and Daphne nodded frantically, no trace of shame in her expression.
"Your slut," she agreed, grinding harder. "Only yours. No one else could ever... could ever make me feel like this."
Harry's mind was reeling. A month ago, Daphne Greengrass wouldn't have admitted to wanting a glass of water from him, let alone begged him to fuck her in public. But something had cracked open between them, some wall had crumbled, and now she was utterly shameless in her desire.
I wonder how far she'd go.
The thought sparked something dark and delicious in Harry's chest. He'd pushed her limits before, in the library, in the corridor, in the bath. Each time, she'd given more of herself than he'd expected. Each time, she'd broken apart more completely on his cock.
"Are you ready for more?" Harry asked, his voice low and rough.
Daphne's grinding faltered slightly. "More?"
Harry's hands slid back down to her arse, and this time one slipped beneath her skirt, his finger tracing along the cleft between her bare cheeks until it found the tight pucker hidden there and pressed just slightly. Daphne's breath caught, her eyes going wide.
"I want to fuck your arse, Daphne."
For a moment, she went completely still in his lap. Harry could feel her heart racing, could see the war playing out across her features, the desire battling against the last remnants of her inhibitions.
"I've never..." she started, then stopped, biting her lip.
"I know."
"It's so big," she whispered, and despite her hesitation, her hips had started moving again, small unconscious circles that betrayed how turned on she was. "Your cock is so fucking big, Harry. I don't know if I could..."
Harry removed his hands from her body entirely.
Daphne made a sound of protest, reaching for him, but Harry caught her wrists and held them between their chests. "Then we don't have to," he said simply. "Your choice."
But he knew her. Knew the competitive fire that burned inside her, knew she couldn't stand to back down from a challenge, knew that telling her she couldn't do something was the surest way to make her prove him wrong.
"No, wait," Daphne said quickly, her chest heaving. "I didn't say... I just..."
Harry waited, his expression neutral even as his cock throbbed painfully beneath her.
"I want to," Daphne finally admitted, her voice barely above a whisper. "I want you to... to fuck my arse. I want to feel you everywhere. I want you to use every part of me."
"Then beg for it."
Daphne's eyes flashed with something that might have been the old competitive fire, but it was quickly swallowed by desperation. She needed him too badly to play games.
"Please," she breathed, her hips rolling against his even though his hands weren't on her anymore. "Please fuck my arse, Harry. Please, I want it, I need it, I need to feel your fat cock stretching my tight little arsehole, filling me up, making me scream, please, please."
Merlin's saggy balls.
Harry's hands returned to her body, one sliding up to cup her tit through her shirt, the other finding her arse again, and Daphne nearly sobbed with relief at the contact.
"Strip," Harry commanded. "Everything off. Now."
Daphne didn't hesitate. She scrambled off his lap and stood before him, her fingers fumbling with the buttons of her shirt in her haste. The fabric parted, revealing more and more of her pale skin, the swell of her tits straining against a thin black bra, her flat stomach, her narrow waist. She shrugged the shirt off her shoulders and let it fall to the floor.
Harry watched, transfixed, as she reached behind her and unclasped her bra. The straps slid down her arms, and then her perfect tits were bare, round and full and topped with those rosy nipples that had featured in his dreams for weeks now. They swayed gently as she let the bra fall, the cool dungeon air puckering her skin.
"Keep going," Harry said, his voice rough.
Daphne's fingers found the zipper at the side of her skirt. The sound of it coming down seemed impossibly loud in the quiet common room. She let the fabric pool around her feet, stepping out of it, and Harry's breath caught at the sight of her.
She wasn't wearing panties.
She'd been planning this, hoping for this, probably spent all day with her bare cunt getting wetter and wetter at the thought of what they'd do tonight.
"Fuck, Daphne," Harry groaned, drinking in the sight of her. Her legs went on forever, long and pale and perfect, leading up to the junction of her thighs where her pussy glistened visibly, her pink folds slick with arousal. Her stomach was flat and toned, her tits heavy and perfect, her nipples peaked in the cool dungeon air. And her face, her beautiful face, was flushed with desire, her blue eyes glazed with need, her lips parted and swollen from where she'd been biting them.
"Anyone could walk down right now," Harry said, and he saw the shiver that ran through her at his words. "Anyone could step out of those dormitories and see you standing there, completely naked, dripping wet and desperate for my cock."
"I know," Daphne whispered, and she sounded almost drunk on the risk of it, on the exposure, on the complete surrender of her dignity.
"You wouldn't have time to hide. Wouldn't have time to get dressed. Everyone would see you. Everyone would know what a desperate little slut you've become."
"I don't care," Daphne breathed, and Harry believed her. "I don't care who sees. I just need you."
Fuck, she's perfect.
"Bend over," Harry commanded. "Hands on the table. Arse in the air."
Daphne turned to face the coffee table in front of the sofa, her arse now presented to Harry in all its glory, those perfect round cheeks pale and firm and just begging to be groped. She bent forward, placing her palms flat on the dark wood, and the movement caused her back to arch, her arse to push out, her cunt and arsehole both visible between her spread thighs.
Harry stood up behind her, his eyes roaming over the sight before him. Her pussy was absolutely drenched, arousal coating her inner thighs, her pink folds glistening and swollen with need. Above it, her tight little arsehole twitched slightly, as if anticipating what was to come.
He reached down and freed his cock from his trousers, the thick length springing free, already rock hard and throbbing. Twelve inches of pure need, the head swollen and angry, straining toward her like it knew exactly where it wanted to be.
Harry stepped closer, letting his cock rest in the cleft of Daphne's arse, the shaft hot against her skin. She moaned at the contact, pushing back against him, and he could feel the wet heat of her cunt pressed against his balls.
"Please," Daphne whimpered. "Please, Harry, don't tease me."
"Patience," Harry murmured, sliding his cock down until the head brushed against her dripping pussy. He pressed forward just enough to coat himself in her slickness, sliding through her folds, gathering her arousal, and Daphne keened at the sensation.
"Oh fuck, just put it in, please, I need it inside me!"
But Harry had other plans. He worked himself through her wetness, sliding back and forth through her folds, letting her juices coat his entire length until his cock was glistening with her arousal. Daphne was trembling beneath him, her fingers clawing at the table, her hips trying desperately to angle him inside her.
"So eager," Harry said, and he positioned the head of his cock against her tight little arsehole.
Daphne's entire body tensed. "Wait, I... oh..."
Harry pressed forward, just slightly, and watched in fascination as her hole began to stretch around his tip. She was impossibly tight, her ring of muscle resisting, but her body was so wet, so slick with her own arousal, that the pressure was slowly forcing her open.
Holy fuck.
The sight was almost too much. His massive cock, thick and veined and glistening, pressed against her tiny entrance, that perfect pucker stretching wider and wider as he pushed forward. She looked so small compared to him, so delicate, and yet her body was slowly, reluctantly, accepting him.
"Breathe," Harry instructed, his voice strained. "Relax. Let me in."
"It's so big," Daphne gasped, but she was pushing back against him, her body contradicting her words. "Oh fuck, it's so fucking big."
Harry kept the pressure steady, watching, mesmerised, as the head of his cock finally popped past her tight ring of muscle.
"OH!" Daphne cried out, her whole body jolting. "Oh Merlin! Oh fuck!"
She's so tight. Fuck, she's so fucking tight.
Harry had to stop moving, had to give her a moment to adjust, because the sensation was overwhelming. Her arse gripped him like nothing he'd ever felt, every tiny twitch of her muscles squeezing around just the head of his cock. He could feel her body fighting itself, clenching and relaxing, trying to accommodate his girth.
"Are you okay?" Harry managed, his voice rough with barely contained need.
"Yes," Daphne gasped. "Yes, just... give me a moment... oh fuck, I can feel you throbbing inside me."
Harry could feel it too, could feel his cock pulsing with his heartbeat, could feel her tight walls rippling around him in response. This was insane. This was absolutely fucking insane. He had the head of his cock in Daphne Greengrass's virgin arse, in the middle of the Slytherin Common Room, with half the house sleeping just up those stairs.
"More," Daphne whimpered. "Please, Harry, give me more. I can take it. I want to feel all of you."
Harry pushed forward, slowly, inch by agonising inch, and watched as his thick shaft disappeared into her tight hole. Daphne's hands were clawing at the table now, her back arching, her moans growing louder with each inch he fed her.
"So deep," she gasped. "You're so fucking deep! I can feel you in my stomach!"
Harry was only halfway in, and she already sounded like she was losing her mind. He kept going, kept pushing, kept feeding her more and more of his cock until finally, finally, his hips pressed against her arse cheeks and he was buried to the hilt.
"All of it," Harry groaned, grinding against her. "You took all twelve inches in your tight little arse."
"Oh fuck," Daphne whimpered, trembling beneath him. "Oh fuck, oh fuck, I feel so full. I've never felt this full. Your cock is splitting me open!"
Harry pulled back slowly, watching as his glistening shaft emerged from her stretched hole, then pushed back in with a smooth thrust. Daphne cried out, her fingers scrabbling against the wood, and Harry did it again, and again, setting a slow, steady rhythm.
"More," Daphne begged, pushing back to meet his thrusts. "Harder! Please, Harry, fuck my arse harder!"
If that's what she wants...
Harry grabbed a fistful of her platinum blonde hair, yanking her head back, and she screamed in pleasure. His other hand gripped her hip, fingers digging into her flesh, and he began to fuck her in earnest.
The sound of his hips slapping against her arse echoed through the common room, loud and obscene, mixing with Daphne's increasingly desperate moans. Each thrust drove his cock deep into her tight channel, each withdrawal dragged against her sensitive walls, and Daphne was rapidly losing what little composure she had left.
"YES!" she screamed, not even trying to keep quiet anymore. "YES, FUCK MY ARSE! I LOVE YOUR COCK! I LOVE FEELING IT IN MY TIGHT LITTLE HOLE!"
"The whole castle is going to hear you," Harry growled, but he didn't slow down. If anything, he fucked her harder, his balls slapping against her dripping cunt with each thrust.
"LET THEM HEAR!" Daphne cried. "I DON'T CARE! I JUST NEED MORE! FILL ME UP! PLEASE FILL MY ARSE WITH YOUR CUM!"
Harry's grip on her hair tightened, forcing her back to arch even more dramatically, her tits jutting out, her face tilted toward the ceiling. He could see her expression from this angle, could see the ecstasy written across her features, her eyes rolled back, her mouth open in a continuous moan of pleasure.
"You're such a perfect little slut," Harry groaned, pounding into her. "Taking my cock in your arse like you were made for it!"
"I was!" Daphne screamed. "I was made for your cock! Every part of me belongs to you! USE ME!"
Harry's mind was reeling. This couldn't be real. This couldn't be happening. Daphne Greengrass, the Ice Queen of Slytherin, bent over a table in her own common room, taking his cock in her arse, screaming filth at the top of her lungs for anyone to hear.
But it was real. Her tight hole was clenching around him, her body trembling beneath his hands, her screams echoing off the stone walls. And Harry could feel his orgasm building, could feel the pressure mounting at the base of his spine, his balls drawing up tight.
"Fuck," Harry groaned, his thrusts becoming erratic. "Fuck, Daphne, I'm going to cum."
"Do it!" Daphne cried, pushing back against him desperately. "Cum in my arse! Fill me up! I want to feel your hot seed deep inside me!"
Harry buried himself as deep as he could go, his cock throbbing, and then he came.
His cock pulsed, and pleasure tore through him so hard his vision went white. Rope after rope of thick, hot cum shot directly into Daphne's arse, flooding her insides, filling her up. His cock kept pulsing, kept pumping, his seed pouring deep into her tight channel like his body was trying to empty itself inside her.
"YES!" Daphne screamed, and Harry could feel her body seizing beneath him, her own orgasm triggered by the sensation of his release flooding her insides. "I'M CUMMING! OH FUCK, I'M CUMMING WITH YOUR FAT COCK BURIED IN MY ARSE!"
Her walls clenched around him, spasming wildly, milking every last drop of cum from his throbbing cock. Harry held her up by her hair as her legs gave out, her whole body shaking with the force of her release, her screams echoing through the common room.
"FUCK! FUCK! HARRYYYYYY!"
The pleasure seemed to go on forever, wave after wave crashing over both of them, their bodies locked together in ecstasy. Harry could feel his cum leaking out around his shaft, unable to fit any more inside her, dripping down between her thighs to mix with the arousal still coating her cunt.
Finally, the intensity began to fade. Harry's grip on Daphne's hair loosened, and she slumped forward onto the table, her chest heaving, her body still trembling with aftershocks.
Harry began to slowly withdraw his cock, watching in fascination as her stretched hole clung to his shaft, reluctant to let go. When the head finally popped free, he groaned at the sight that greeted him.
Daphne's arse was gaping slightly, her hole red and swollen and twitching, and as he watched, a thick stream of his cum began to leak out. She clenched involuntarily, and more spurted free, dripping down over her pussy and onto the table beneath her.
"Fuck," Harry breathed, drinking in the sight of his handiwork.
She was absolutely perfect.
