DESCRIPTION

NOTE: Chapter 22 has also been posted with the full chapter text in addition to the website, which should make it easier to read for those who haven't already. If there are any problems I'll try to catch them quickly and publish the PDFs and EPUBs also.

Disclaimer: This story is set in a timeline where Harry Potter has defeated Voldemort and is exploring life after Hogwarts. All characters featured in this story are 18+, and none of them are related.

Harry stared down at the sight before him, his brain struggling to process what his eyes were showing him.

Hermione Granger was on her knees on his sister's bed, face pressed into the pillows, her magnificent arse thrust up into the air like an offering to some ancient and thoroughly depraved god. Her hands were still gripping her own cheeks, pulling them apart, spreading herself open to reveal the tight pink pucker of her arsehole and the glistening folds of her pussy below. The too-small skirt was bunched uselessly at her lower back, and her tits hung heavy beneath her, swaying gently with each nervous breath she took.

And Harry was standing right behind her, his cock so hard it ached, pointing directly at the tightest hole he'd ever been asked to fuck.

This is actually happening, he thought, running his thumb over her rosebud again just to watch it clench. After an entire morning of being teased and stroked and sucked and denied, I'm about to sink my cock into Hermione Granger's virgin arse.

"Look at her," Daphne breathed from somewhere behind him, the phone capturing every moment. "Look at that tight little hole, just waiting for you to stretch it open."

Harry looked. Merlin, did he look. Hermione's arsehole was a small, puckered ring of muscle, pink and perfect and clenching nervously under his gaze. It was impossibly tiny compared to the thick, throbbing cock he was about to shove into it, and the contrast made his balls tighten with anticipation. Just below, her pussy was dripping with arousal, her swollen lips parted and glistening, and Harry could see her clit peeking out from its hood, flushed and needy.

"She's so wet," Iris said from the bed beside Hermione, and Harry's gaze drifted to his sister. She was lying on her side, propped up on one elbow, close enough that her tits were nearly brushing against Hermione's arm. The blue crop top had given up entirely at some point, hanging open to reveal those perfect round breasts with their rosy, hardened nipples. Her other hand had disappeared beneath her tiny skirt, and Harry could see the movement of her fingers between her thighs, could hear the wet sounds as she played with herself. "Look at her pussy, Harry. She's absolutely dripping for you."

Fuck. His sister was fingering herself while she watched him prepare to fuck her best friend's arse. His cock jumped at the thought, slapping against Hermione's spread cheeks, and she let out a muffled whimper into the pillow.

"Please," Hermione breathed, her voice muffled but desperate. "Harry, please. I need it."

"You heard her," Daphne said, and suddenly she was right behind him, her bare tits pressing against his back, her chin hooking over his shoulder to watch from his point of view. One hand held the phone steady, angled to capture everything, while the other slid around his hip to wrap around the base of his cock. "Give her what she needs."

She guided him forward, and Harry felt the swollen head of his cock press against Hermione's tight entrance. The muscle clenched against him, resisting, and Hermione let out a sharp gasp.

"Relax," Iris cooed, her free hand reaching out to stroke Hermione's hair, pushing the wild brown curls away from her flushed face. "You can take it, Hermione. You can take his big, fat cock. Just breathe and let him in."

Just breathe and let him in. His sister was coaching her best friend through taking his cock in her arse while she fingered herself. Harry's mind was reeling, unable to fully process the absolute madness of this situation, but his body knew exactly what to do.

He pushed forward.

Hermione's body resisted for a long, agonising moment, her tight ring of muscle refusing to yield. Harry could feel her clenching against him, could feel the pressure building as he pressed forward, and then suddenly something gave. The head of his cock popped past her sphincter, and Hermione cried out into the pillow, her whole body going rigid beneath him.

Sweet fucking Merlin.

The tightness was unlike anything Harry had ever felt. Hermione's arse gripped the head of his cock with an intensity that made his vision blur, her inner walls squeezing him so hard it was almost painful. She was hot inside, impossibly hot, and so fucking tight that Harry had to stop himself from simply ramming forward and burying himself to the hilt.

"Oh!" Hermione cried out, her fingers tightening on her own arse cheeks. "Oh, Merlin, it's... it's..."

"Big?" Iris supplied helpfully, her fingers still working between her own thighs. Her emerald eyes were fixed on the point where Harry's cock had breached Hermione's arse, watching with undisguised fascination. "Is his big cock stretching your tight little hole, Hermione?"

"Yes!" Hermione gasped. "It's so... I feel so full, and he's barely..."

"Barely inside," Daphne finished, her breath hot against Harry's ear. "Look at that, Harry. Just the tip, and she's already falling apart. Imagine how she'll sound when you're balls deep."

Harry didn't have to imagine. He was going to find out.

He pushed forward another inch, and Hermione's whole body shuddered. Her arse gripped him even tighter, the muscle spasming around his shaft as it tried to adjust to his girth. Harry watched, transfixed, as another inch of his cock disappeared into her body, the pink ring of her arsehole stretching obscenely around his thick shaft.

"More," Hermione whimpered into the pillow. "Please, Harry, more."

More. The shy bookworm who blushed when he looked at her too long was begging him for more cock in her arse. Harry's brain was short-circuiting, but his hips knew what to do. He pressed forward again, sinking another two inches into her tight channel, and Hermione let out a moan so loud and so filthy that he felt it vibrate through his entire body.

"That's it," Iris encouraged, her own breathing growing heavier as her fingers moved faster beneath her skirt. "Take it, Hermione. Take his cock. You look so fucking good like this."

Harry pulled back slightly, just an inch, and then pushed forward again. Hermione's arse yielded a little more easily this time, accepting another inch of his length, and she let out another of those incredible moans. He could see her tits swaying beneath her with each thrust, those big, soft globes hanging heavily, her hard nipples nearly brushing the bed sheets.

"Daphne," Harry managed, his voice strained. "Get... get a shot of her tits."

"On it." Daphne peeled herself away from his back and circled around to the side of the bed, dropping to her knees to get a low angle. The phone captured Hermione's face, flushed and contorted with pleasure, and then panned down to her hanging tits. They swayed with each small movement Harry made, rippling softly, and Daphne reached out with her free hand to cup one, lifting it for the camera.

"Look at these," Daphne said admiringly, giving Hermione's breast a squeeze that made the other girl moan. "Perfect tits on the smartest witch at Hogwarts, and she's getting her arse stretched open by the biggest cock she's ever seen."

Harry thrust forward again, harder this time, and sank another two inches into Hermione's impossibly tight channel. He was more than halfway in now, his thick shaft stretching her arsehole wide, and the sensation was driving him mad. Every inch of him was gripped by her tight, hot walls, squeezed so hard that he could feel his pulse throbbing against her insides.

"Merlin!" Hermione cried out, her back arching. "Merlin, Harry, you're so deep!"

"Not yet," Harry grunted. "You've got a lot more to take."

He gripped her hips, his fingers digging into her soft flesh, and pulled her back as he pushed forward. The final inches of his cock sank into her arse, and his balls finally came to rest against her dripping pussy, and Hermione let out a scream of pleasure that probably echoed through the entire manor.

Balls deep in Hermione Granger's arse. Harry held himself there, buried completely inside her, feeling her tight walls spasm and clench around his entire length. Her arsehole was stretched so wide around his base that he could see the pink muscle straining, her body pushed to its absolute limit to accommodate his size.

"Holy fuck," Iris breathed, her fingers stilling between her thighs as she stared at the junction of their bodies. "You actually fit. Your whole cock actually fit inside her arse."

"Told you she could take it," Daphne said smugly, still filming from the side. "Hermione's always been an overachiever."

Hermione let out a delirious laugh that turned into a moan when Harry shifted his hips. "I can feel you in my stomach," she whimpered. "Merlin, Harry, I can feel every inch of you. It's so much. It's too much. It's not enough. Please. Move. Please move!"

Harry didn't need to be told twice.

He pulled back slowly, watching in fascination as his cock emerged from Hermione's stretched arsehole inch by glistening inch. Her body clung to him desperately, her inner walls refusing to release their grip, and the sensation of those tight muscles dragging along his shaft made Harry's eyes roll back in his head.

Then he thrust forward.

Hermione screamed.

Not a scream of pain, no, this was pure, unfiltered pleasure, ripped from her throat as Harry's cock plunged back into her arse in one long, deep stroke. Her whole body shook with the impact, her tits swinging wildly beneath her, her fingers clawing at the sheets as she tried to anchor herself against the onslaught.

"Again!" she begged, her voice cracking. "Again, Harry! Fuck my arse!"

Harry obliged. He set up a rhythm, pulling back until just the head of his cock remained inside her tight hole, then driving forward until his balls slapped against her soaking pussy. Each thrust drew another cry from Hermione's lips, each impact sent her tits swaying and her arse cheeks rippling, and the wet sounds of his cock pistoning in and out of her tight channel filled the room.

"Look at her," Daphne breathed, circling behind Harry again to capture the view from over his shoulder. "Look at Hermione Granger taking cock in her arse like she was born for it."

I'm watching, Harry thought dazedly, his eyes fixed on the point where his shaft disappeared into Hermione's body again and again. I'm watching my cock stretch her arsehole wide open, and she's begging for more, and my sister is fingering herself right next to us, and this is actually my life now.

"Harder!" Hermione demanded, pushing her arse back to meet his thrusts. "Please, Harry, harder! I want to feel you for days!"

Harry grabbed her hips and gave her exactly what she wanted. He pounded into her with everything he had, his hips snapping forward with a force that made her whole body jerk. The sound of flesh slapping against flesh echoed through the room, mixing with Hermione's increasingly incoherent moans and the wet squelch of her dripping pussy.

"Fuck, that's hot," Iris moaned, and Harry glanced over to see his sister had given up all pretence of subtlety. She'd kicked off her skirt entirely and spread her legs wide, her fingers buried in her own pussy as she watched Harry fuck her best friend's arse. Her tits were heaving, her nipples rock hard, and her emerald eyes were glazed with lust. "Look at her take it. Look at your cock stretching her arse. Merlin, I want..."

She cut herself off, biting her lip, but Harry heard what she hadn't said. He saw it in the way she stared at the junction of their bodies, the way her thighs squeezed around her own hand, the way she unconsciously licked her lips.

She wants this, Harry realised, his cock throbbing at the thought. Iris wants my cock in her arse.

"What do you want, Iris?" Daphne asked, moving around to film Harry's sister in her debauched state. "Tell the camera what you want."

"I..." Iris's face flushed even redder, but she couldn't tear her eyes away from where Harry's cock was pounding into Hermione. "I want to know what it feels like."

"What what feels like?"

"That!" Iris gestured helplessly at Hermione, who was now moaning continuously, her face buried in the pillows, her arse thrust high in the air to give Harry the best possible angle. "What Hermione's feeling. What it feels like to have... to have his cock in my..."

"Your arse?" Daphne supplied with a wicked grin. "You want Harry to fuck your arse too?"

Iris let out a whimper that was answer enough.

Fuck. Harry's pace faltered for a moment as his brain tried to process this new information. His sister wanted his cock in her arse. She was lying there, legs spread, pussy dripping, openly admitting that she wanted him to do to her what he was doing to Hermione.

"Later," Daphne said firmly, returning her attention to the main event. "Right now, this is Hermione's moment. Harry, make her cum. Make her cum with your cock in her arse."

Harry returned his full attention to Hermione, who was pushing back against him with desperate, frantic movements. He could feel how close she was, could feel her arse clenching rhythmically around his cock, her body building toward an orgasm that was going to be absolutely devastating.

He reached around her hip and found her clit.

Hermione's reaction was instantaneous. Her whole body seized up, her arse clamping down on his cock so hard he saw stars. She screamed into the pillow, a raw, primal sound of pleasure, and Harry felt her pussy gushing against his fingers, her orgasm crashing through her with the force of a tidal wave.

"I'm cumming!" she wailed, her words barely coherent. "Merlin, Harry, I'm cumming! Don't stop! Don't you dare stop!"

Harry didn't stop. He fucked her through her orgasm, his cock driving into her spasming arse again and again, his fingers circling her clit to draw out every last wave of pleasure. Hermione was shaking, trembling, her whole body wracked with ecstasy, and the sounds coming out of her mouth were no longer words, just pure, animalistic expressions of pleasure.

And Harry was right there with her.

After an entire morning of being teased and stroked and sucked without release, after watching three of the most beautiful women he'd ever seen parade around naked and rub their bodies against his, after sinking his cock into the tightest hole he'd ever experienced, Harry couldn't hold back any longer.

"Hermione," he grunted, his pace growing erratic. "I'm going to... fuck, I'm going to cum!"

"Inside!" Hermione gasped, pushing her arse back against him. "Cum inside my arse, Harry! Fill me up! I want to feel it!"

That was all the permission Harry needed.

He buried himself to the hilt in her tight arse and let go.

The orgasm tore through him without warning. His entire body seized up, his cock swelling inside her impossibly tight channel, and then he was cumming, pumping rope after rope of hot seed deep into Hermione's arse. The release was so intense that his vision actually went white, his mind emptying of everything except the overwhelming pleasure pulsing through him.

He came and came and came, filling her with more cum than he'd thought possible, feeling her tight walls milk him for every last drop. Hermione was moaning beneath him, her arse still clenching rhythmically around his spurting cock, her own orgasm extending as she felt his hot seed flooding her insides.

"Merlin," Iris breathed from beside them, and Harry vaguely registered the sound of her own orgasm, her fingers working furiously between her thighs as she watched her brother pump his load into her best friend's arse.

Finally, after what felt like an eternity, the waves of pleasure began to subside. Harry slumped forward, catching himself on his hands, his cock still buried inside Hermione's arse. Both of them were panting, their bodies slick with sweat, and Harry could feel his cum leaking out around his softening shaft.

"Got it all," Daphne announced smugly, lowering the phone. "That was incredible. Our followers are going to lose their minds."

Harry didn't give a damn about the followers. He was too busy staring down at Hermione, who had collapsed face-first into the pillows, her arse still raised in the air, her arsehole stretched and dripping with his cum. She looked thoroughly, completely, devastatingly fucked.

He pulled out slowly, watching in fascination as his cock emerged from her stretched hole, followed by a thick trickle of white that ran down toward her still-dripping pussy. Hermione let out a soft whimper at the loss, her arsehole gaping slightly, clenching on nothing.

Harry couldn't resist. He raised his hand and brought it down on her arse cheek in a sharp spank.

The impact made her whole body jerk, made her arse cheeks ripple beautifully, and made more of his cum leak from her stretched hole. Hermione let out a startled moan, her fingers curling into the sheets even as her back arched into the sting.

"Harry!" she whimpered, but she didn't tell him to stop.

So he did it again.

Smack.

Another ripple. Another trickle of white. Another moan from Hermione's lips.

"Fuck," Iris breathed, her fingers still buried in her own pussy. "That's so hot. Look at your cum dripping out of her."

Harry looked. He watched his seed leak from Hermione's well-fucked arse, watched it run down over her swollen pussy lips, watched it drip onto the sheets beneath her. Hermione Granger, the smartest witch of her age, was lying face-down on his sister's bed with his cum leaking from her stretched arsehole, and all Harry could think was that he wanted to do it again.

Daphne captured a few final shots of the aftermath, zooming in on Hermione's cum-filled arse, then panning up to Harry's satisfied, still-slightly-stunned expression.

"Perfect," she declared, grinning. "Absolutely perfect. This is going to break WitchTok."

Let it break, Harry thought, his eyes still fixed on the beautiful mess he'd made of Hermione Granger. Let the whole damn thing burn.
