Harry's hips slammed forward with a wet slap, driving every thick inch of his cock into Luna's soaking cunt. She was bent completely in half beneath him, her knees pressed against her ears, her slender body folded like a pretzel as he used her for his pleasure. The position left her utterly helpless, unable to do anything but take whatever he gave her.
"Oh, Harry," Luna sighed dreamily, her silvery eyes gazing up at him with that characteristic unfocused look. "That feels quite nice."
Nice, Harry thought with a grunt, pulling back until only his swollen head remained inside before plunging back in. I've been pounding this tight little cunt for twenty minutes and all she can say is 'nice'.
He watched her face for any sign of approaching orgasm, any flutter of her pale lashes or parting of her pink lips that might indicate she was close. Nothing. Luna looked as serene as if she were lying in a meadow watching clouds, not getting fucked senseless by twelve inches of rock-hard cock.
Her pussy was incredible, he had to admit. Tight as a vice and wet as anything, her inner walls gripping him like they never wanted to let go. Each thrust made obscene squelching sounds, her arousal coating his shaft and dripping down onto the sheets below. Her lithe body was a work of art, all pale skin and delicate curves, her small but perfect breasts bouncing with each impact.
Harry had stumbled upon her in the cabin's smaller sitting room not thirty minutes ago. She'd been doing some sort of stretching exercise in nothing but an oversized t-shirt, and when she'd bent forward to touch her toes, the shirt had ridden up to reveal she wasn't wearing anything underneath. The sight of her pale, heart-shaped arse and the glimpse of her pink pussy peeking out between her slender thighs had been too much to resist.
Luna, being Luna, had simply looked at him over her shoulder and asked if he wanted to fuck her. No preamble, no seduction. Just a matter-of-fact question delivered with the same tone one might use to ask about the weather.
And now here they were. Luna bent in half on the floor, her knees by her ears, and Harry pistoning into her with increasing desperation.
The problem was that despite her pussy being wonderfully tight and wet, despite the way her walls fluttered around him with each thrust, Harry could feel himself rapidly approaching the edge while Luna seemed content to simply... enjoy the sensation. Her soft moans were pleasant but nowhere near the screaming orgasms he'd wrung from the other witches.
Come on, he thought, angling his hips to try and find that special spot inside her. There must be something that gets her off.
He shifted his weight, drove in deeper, harder. Luna's eyes widened slightly, her lips parting in a soft gasp. That was something, at least. Harry focused on that angle, pounding into her with renewed determination.
"Oh my," Luna breathed, her voice still irritatingly calm. "You're very determined, aren't you?"
Harry grunted in response, sweat beading on his forehead as he fought against the pressure building in his balls. His cock throbbed inside her, desperate for release, but he refused to cum until she did. It was a matter of pride at this point.
Luna's head tilted to the side, studying him with those unnervingly perceptive silver eyes. "You're frustrated."
"I'm fine," Harry managed through gritted teeth, his hips never slowing their relentless rhythm.
"You're close to cumming but I'm not." It wasn't a question. Luna stated it as simple fact, her voice dreamy even as her body jolted with each powerful thrust. "That's very sweet of you, Harry. Most wizards wouldn't care."
Harry's rhythm faltered slightly. He hadn't meant to be so obvious about it. "I want you to feel good too, Luna."
A genuine smile crossed her delicate features, transforming her from ethereally beautiful to breathtakingly stunning. "I do feel good. Your cock is quite lovely. Very thick." She hummed appreciatively as he thrust particularly deep.
Quite lovely, Harry thought with a mixture of amusement and frustration. I'll show her quite lovely.
And then, like a bolt of lightning, Lily's words from the first night echoed through his mind.
But Luna's favourite thing is anal. It would be a tight fit, with Luna's lithe frame, but there is nothing she would love more.
Harry's cock twitched hard inside Luna at the memory, and she must have felt it because her eyes sparkled with sudden interest.
"Oh, you've thought of something," she observed, her voice taking on a hint of breathlessness for the first time.
Harry slowly pulled out of her cunt, watching as her pink lips clung to his shaft, reluctant to let him go. His cock emerged glistening with her juices, all twelve inches standing proud and hard, the prominent veins pulsing with need.
"Turn over," Harry commanded, his voice rougher than intended.
Luna complied without question, unfolding her limber body and rolling onto her stomach. She rose onto her hands and knees, presenting her arse to him like an offering. Harry's breath caught in his throat.
Merlin's beard.
Her arse was a work of art. Small but perfectly formed, two pale globes that curved invitingly. Her waist was impossibly narrow, flaring out to those delicate hips, and her spine created a beautiful arch as she lowered her shoulders to the floor, raising her rear end even higher.
Harry reached out and palmed one perfect cheek, marvelling at how soft and smooth it felt beneath his hand. He spread her open slowly, reverently, and was rewarded with a sight that made his cock jump.
Her tiny rosebud winked at him, pink and puckered and impossibly small. Below it, her pussy glistened with arousal, but it was that forbidden hole that captured his attention now. It looked far too tight for his massive cock, and for a moment Harry wondered if Lily had been exaggerating.
Luna looked back at him over her shoulder, her silver eyes gleaming with something new. Something hungry. "You remembered what Lily said."
"She mentioned you like it in the arse," Harry admitted, pressing his thumb gently against her puckered entrance. Luna shuddered, her entire body trembling.
"I do," Luna whispered, and for the first time since they'd started, there was real urgency in her voice. "I really, really do."
Harry gathered some of her copious arousal on his fingers and began to work it around her tight hole. The moment he pressed a finger against her entrance, Luna let out a moan that was decidedly different from her previous sounds of pleasure. This was needier, more desperate.
"More," she breathed, pushing back against his hand. "Please, Harry. I can take more."
He slipped one finger inside, and the heat was incredible. So much tighter than her pussy, gripping his finger like it never wanted to let go. Luna's moan turned into something closer to a whimper, her hips rolling back to take him deeper.
"Yesss," she hissed, her calm demeanour finally cracking. "Oh, that's much better."
Harry worked his finger in and out slowly, watching in fascination as her tight ring stretched to accommodate him. He added a second finger, and Luna's arms gave out entirely. She collapsed forward, her cheek pressed against the floor, her arse still raised high in the air.
"More, more, more," she chanted, her voice high and breathy. "Please, Harry. I need your cock. I need it in my arse."
The desperation in her voice sent a thrill through Harry's body. This was more like it. He withdrew his fingers and positioned the swollen head of his cock against her tiny entrance.
"This is going to be tight," he warned, pressing forward just enough to feel resistance. "You sure you can take all of me?"
Luna looked back at him, and her silver eyes were wild with need. "I've never had anything this big," she admitted, her voice trembling with anticipation rather than fear. "But I want it. I want all of it. Please, Harry. Fill my arse with that magnificent cock."
Harry pushed forward.
The pressure was immense. Luna's arse resisted at first, that tight ring of muscle refusing to yield. But Harry was patient, maintaining steady pressure, and slowly the head of his cock began to slip inside.
"Oh Merlin!" Luna cried out as the swollen head popped past her tight ring. "Oh fuck, oh fuck, you're so big!"
Harry froze, giving her time to adjust. The sight before him was almost too much. His thick shaft stretching her tiny hole, her pale arse cheeks spread wide around his girth. It looked obscene. It looked impossible. There was no way she could take all of him.
But Luna was pushing back, her body trembling as she tried to impale herself further on his cock.
"Don't stop," she begged, her voice cracking. "Please don't stop. I need more. I need all of it!"
Harry pushed deeper, inch by impossible inch, watching in awe as Luna's tiny body swallowed his massive cock. Her arse stretched obscenely around him, her inner walls gripping him so tightly it was almost painful. The pressure was incredible, unlike anything he'd ever felt before.
How is this possible? he thought dazedly. She's so small. So tight. How is she taking all of me?
Halfway in, Luna let out a sound that was part moan, part scream, part sob of pure pleasure. Her entire body was shaking, her fingers clawing at the floor, her breath coming in desperate gasps.
"More," she whimpered. "Please, Harry. More. I can take it. I need it all."
Harry obliged, pushing deeper still. Three quarters of the way in and Luna was making sounds he'd never heard from any woman before. High, keening wails of pleasure that seemed to come from somewhere deep inside her. Her arse clenched rhythmically around his shaft, massaging him in ways that made his eyes roll back in his head.
And then something snapped inside Harry.
Maybe it was the way her arse gripped him. Maybe it was the desperate, needy sounds falling from her lips. Maybe it was the sight of her tiny frame stretched around his massive cock. Whatever it was, Harry's patience evaporated in an instant.
With a growl that bordered on feral, Harry grabbed Luna's hips in a bruising grip and slammed forward. The last three inches of his cock buried themselves in her arse in one brutal thrust, his pelvis crashing against her pale cheeks with enough force to drive her face-first into the floor.
Luna's scream could have shattered glass.
"FUCK!" she shrieked, her entire body going rigid beneath him. "OH FUCK, HARRY! YOU'RE SO DEEP! I CAN FEEL YOU IN MY STOMACH!"
Harry didn't apologise. Couldn't apologise. The sensation of her impossibly tight arse wrapped around every last inch of his cock had short-circuited his brain entirely. His balls pressed against her dripping cunt, and he could feel her inner walls spasming wildly around him, gripping and releasing in desperate pulses.
And then Luna came.
Her scream cut off into a strangled sob as her body convulsed beneath him. Her arse clamped down on his cock so hard Harry saw stars, pulsing and spasming in waves of pleasure that seemed to go on forever. Her back arched despite being pinned to the floor, her toes curled, and she squirted all over the hardwood beneath her, her cunt gushing even though nothing was inside it.
"HARRY!" she wailed, her voice raw and broken. "HARRY, HARRY, HARRY! I'M CUMMING! YOUR COCK SPLIT ME OPEN AND I'M CUMMING!"
Harry held still through her orgasm, marvelling at the sensation of her arse milking his cock. It was nothing like her pussy. Where her cunt had been wet and welcoming, her arse was tight and demanding, gripping him with a strength that threatened to pull the orgasm right out of him.
When her shudders finally began to subside, Luna lay boneless beneath him, her cheek pressed against the floor, her silver hair spread around her like a halo. Her breath came in ragged gasps, her pale skin flushed a beautiful pink.
"That was..." she panted, struggling to form words. "That was the best orgasm I've ever had. And you haven't even started moving yet."
A slow grin spread across Harry's face. "Then hold on tight, Luna. Because I'm just getting started."
He pulled back slowly, watching as her pink rim clung to his shaft, stretching outward as if trying to keep him inside. Luna whimpered at the withdrawal, her fingers scrabbling against the floor.
"Don't take it out," she begged. "Please, Harry. I need it. I need your cock in my arse."
"I'm not taking it out," Harry promised, pausing when just the swollen head remained inside her. "I'm going to fuck you."
He slammed back in.
Luna screamed again, her whole body jolting forward from the impact. Her small tits dragged against the floor, her nipples hard and sensitive. Harry didn't give her time to recover. He pulled back and thrust again, and again, setting a brutal rhythm that had her crying out with every stroke.
"YES!" Luna shrieked, her dreamy composure utterly destroyed. "YES, YES, YES! FUCK MY ARSE, HARRY! USE ME! RUIN ME!"
The sounds filling the room were obscene. The wet slap of Harry's pelvis against Luna's pale cheeks. The squelch of her well-lubricated hole stretching around his massive girth. Her screams of pleasure echoing off the walls. His own grunts of effort as he pounded into her with everything he had.
This is what she needed, Harry thought triumphantly, watching his cock disappear into her tiny body over and over. Not her pussy. Her arse. Merlin, she's incredible.
Luna's hands found purchase on the floor, and she started pushing back to meet his thrusts, impaling herself on his cock with desperate abandon. The sight of her slim body stretched around him, her pale arse cheeks rippling with each impact, was almost too much to bear.
"More!" Luna demanded, her voice high and broken. "Harder, Harry! I won't break! Fuck me like you mean it!"
Harry obliged, his hips becoming a blur as he pounded into her with savage intensity. Each thrust drove her forward, her tits dragging against the floor, her breath coming in short, sharp cries. Her arse gripped him like a velvet vice, milking his cock with every stroke.
"Fuck, Luna," Harry groaned, feeling his orgasm building at the base of his spine. "Your arse is incredible. So fucking tight. Can't believe you're taking all of me."
"All yours," Luna gasped, her words punctuated by his thrusts. "My arse is all yours, Harry! Whenever you want it! Just grab me and bend me over and fill me up!"
The mental image nearly pushed Harry over the edge. Luna, bent over the breakfast table. Luna, pressed against the shower wall. Luna, on her knees in the snow outside, her breath misting in the cold air as he pounded her from behind.
"I'm going to hold you to that," Harry promised, reaching around to find her clit. The moment his fingers made contact with the swollen nub, Luna's whole body convulsed.
"FUCK!" she screamed, her arse clenching impossibly tight around him. "I'M CUMMING AGAIN! HARRY, YOU'RE MAKING ME CUM AGAIN!"
Her orgasm was even more intense than the first. Her entire body shook violently, her arse spasming wildly around his cock, her pussy squirting onto the floor in a torrent of pleasure. Luna's screams turned wordless, just pure, raw sounds of ecstasy as wave after wave crashed over her.
Harry fucked her through it, his fingers still working her clit, drawing out her pleasure until she was sobbing beneath him. And still he didn't stop. Couldn't stop. Her arse was milking his cock so perfectly, massaging every inch of his shaft with desperate pulses that made his vision blur.
"One more," Harry commanded, pulling out almost all the way before slamming back in hard enough to make her whole body jolt. "Give me one more, Luna. Cum on my cock one more time and I'll fill your arse with so much seed you'll be leaking for days."
"Yes!" Luna wailed. "Yes, Harry! Fill me up! I want to feel your hot cum deep in my arse! Please, please, please!"
Harry's pace became almost brutal, his hips a blur as he chased both their releases. The pressure building in his balls was immense, his cock throbbing desperately inside her impossibly tight channel. Luna was a mess beneath him, drool pooling on the floor, her eyes rolled back, her body twitching with continuous aftershocks.
"Here it comes," Harry warned, feeling his control finally slip. "Fuck, Luna, I'm going to cum!"
"INSIDE!" Luna screamed, her third orgasm crashing over her. "CUM INSIDE ME! FILL MY ARSE, HARRY! FILL ME UP!"
Harry buried himself to the hilt and came.
The orgasm ripped through him like lightning, starting at the base of his spine and exploding outward until his entire body shook with the force of it. Rope after rope of thick, hot cum flooded Luna's arse, painting her insides white. He came harder than he had all day, harder than he had all week, pumping what felt like endless streams of seed deep into her tiny body.
"So much!" Luna sobbed, her arse still clenching rhythmically around him, milking out every last drop. "I can feel it, Harry! So hot! So deep! It feels like it's going into my stomach!"
Harry's hips jerked with each spurt, driving his cum deeper and deeper inside her. When he finally, finally stopped cumming, he collapsed forward, catching himself on his hands before he could crush her beneath him. They stayed like that for a long moment, both panting heavily, his softening cock still buried in her cum-filled arse.
Slowly, Harry pulled out. His cock emerged with an obscene pop, followed immediately by a river of thick white cum that leaked from Luna's stretched hole. Her arse gaped slightly, unable to close properly after accommodating his massive girth, and Harry watched in fascination as his seed dripped out of her and pooled on the floor.
Luna lay completely boneless, her face still pressed against the hardwood, a dreamy smile on her lips. Her silver eyes were unfocused, but this time it wasn't her usual ethereal distance. This time she looked thoroughly, completely fucked.
"That," Luna breathed, her voice hoarse from screaming, "is exactly what I needed."
Harry laughed weakly, rolling onto his back beside her. His cock lay heavy against his thigh, finally satisfied. "I can't believe you took all of it. You're incredible."
Luna turned her head to look at him, her smile widening. "I told you I could handle it. Though you're much bigger than anything I've had before." She hummed contentedly. "I think I might be ruined for anything else now."
"Is that a complaint?"
"Definitely not." Luna reached out and patted his chest affectionately. "In fact, I think you should do that again. Soon. And often. Whenever the Wrackspurts are making your brain fuzzy, you can just bend me over and clear your head."
Harry snorted, but his cock twitched at the suggestion. "I'll keep that in mind."
They lay in comfortable silence for a moment, both catching their breath. Then Luna sat up, wincing slightly, and Harry watched as more of his cum dripped out of her well-used arse.
"I should probably clean up," she observed mildly, as if discussing the weather rather than the copious amounts of cum leaking from her body. "Though I rather like the feeling of being so full of you."
"Take your time," Harry said, still too boneless to move. "I'm not going anywhere."
Luna smiled at him, that genuine, beautiful smile that transformed her entire face. "Good. Because I meant what I said, Harry. Whenever you want me. Wherever you want me. I'm yours."
