Thanking Harry (Ch. 15 - Hermione's Competition)

Disclaimer: Hogwarts start at the age of 13, making all characters Harry encounter 18+

Harry groaned as he sank deeper into the warm, steaming waters of the prefect's bathroom. After two hours of gruelling Quidditch practice, his muscles ached in the most satisfying way, the heat of the bath working its magic on his tired body. He leaned his head back against the smooth marble edge of the enormous tub, letting his eyes drift shut as the scent of lavender and vanilla filled his lungs.

The bathroom was one of his favourite spots in the entire castle. The massive pool-like tub could easily fit twenty people, and the high vaulted ceiling made even the smallest sounds echo dramatically. Rows of golden taps lined the sides, each dispensing different coloured waters and foams and bubbles, creating a veritable paradise for anyone lucky enough to have access.

Harry had stripped completely naked before climbing into the bath, his clothes discarded carelessly on the floor. Now his body floated peacefully in the warm water, his cock bobbing lazily beneath the surface as he relaxed. The stained glass window depicting a mermaid cast colourful patterns across the water's surface, adding to the dreamlike atmosphere.

He had barely been soaking for fifteen minutes when the bathroom door suddenly burst open with a loud bang that echoed off the marble walls.

"HARRY JAMES POTTER!"

Harry's eyes snapped open to find Hermione storming into the bathroom, her bushy brown hair wild around her face, her cheeks flushed red with what could only be described as fury. She was still wearing her school uniform, though her tie was loose and her shirt was slightly rumpled, as if she'd been running through the castle.

"Hermione?" Harry said, startled. "What's wrong?"

"What's WRONG?" Hermione practically shrieked, her hands balled into fists at her sides. "I'll tell you what's bloody wrong, Harry! I just overheard Lavender and Parvati gossiping in the library about how Astoria Greengrass was walking funny today. Do you know what they were saying?"

Harry felt his stomach drop. Fuck.

"They were saying," Hermione continued, her voice rising with each word, "that you fucked her arse! That you took her anal virginity! Is that true, Harry?"

There was no point in lying. Hermione could always tell when he was being dishonest, and besides, the entire school seemed to know his business these days anyway.

"Yes," Harry admitted, watching as her face went from red to practically purple. "It's true. Yesterday, in her dormitory, I—"

"Yesterday!" Hermione cut him off, her voice reaching a pitch that made the water in the bath vibrate. "Yesterday! And when exactly were you planning to tell me, Harry? Or was I just supposed to find out through castle gossip like everyone else?"

"Hermione, I didn't think—"

"No, you didn't think!" she snapped, pacing back and forth along the edge of the bath. The sound of her shoes clicking on the marble floor echoed dramatically. "Do you have any idea how embarrassing it is to hear about these things second-hand? To have those giggling bimbos looking at me with pity because apparently everyone knows what you've been doing except me?"

Harry pushed himself up slightly in the water, watching her carefully. There was something else beneath her anger, something that made his cock twitch with interest. "Hermione—"

"I'm your best friend, Harry!" she continued, her voice cracking slightly. "If anyone should have been first, it should have been me! Not some Slytherin slut whose sister you're already fucking!"

There it was. Harry felt a grin tugging at his lips despite the situation. This wasn't just about being embarrassed or left out. This was about competition. Hermione's competitive nature, the same drive that made her the top student in every class, the same obsession with being the best, was now focused on pleasing him.

"So that's what this is about," Harry said, his voice low and knowing. "You're jealous."

"I am NOT jealous!" Hermione protested, though the blush spreading down her neck betrayed her. "I just think that as your best friend, as someone who's been there for you through everything, I should have... I mean, you should have..." She trailed off, biting her lip.

"Should have what, Hermione?" Harry prompted, enjoying watching her squirm. "Should have fucked your arse first?"

The crude words made her gasp, her eyes widening. But Harry didn't miss the way her thighs pressed together, or how her nipples suddenly became visible through her shirt.

"Yes!" she finally burst out, her hands flying up in exasperation. "Yes, alright? You should have asked me! I can take it better than that Slytherin tart anyway. I'm smarter, more prepared, and I certainly wouldn't be walking around advertising it to the whole school!"

Harry's cock was now fully hard beneath the water, his arousal clear despite the bubbles. "Is that so?" he said, his voice dropping to a husky growl. "You think you could take my fat cock up your tight little arse better than Astoria did?"

Hermione's breath hitched at his words, her eyes involuntarily dropping to where his erection was visible beneath the water's surface. "I know I could," she said, though her voice was quieter now, breathier. "I've been... I've been preparing myself."

That was a lie, Harry could tell immediately. Hermione's terrible poker face gave her away, but the fact that she was lying only made this more arousing. She wanted it so badly she was willing to pretend she was ready, all because her competitive nature couldn't stand the thought of another girl being better at something.

"Prove it," Harry challenged, spreading his arms along the edge of the bath, putting himself on full display. His thick cock stood proud above the water now, the mushroom head swollen and leaking pre-cum. "Strip and get in here. Show me how well-prepared you are."

Hermione hesitated for only a moment before her fingers flew to her shirt buttons. Harry watched, mesmerised, as she stripped with frantic energy, clearly driven by her competitive fury. Her shirt fell to the floor, followed by her skirt, revealing a matching set of pink lace underwear that made his cock throb.

When did Hermione start wearing such sexy panties? Harry wondered, though he wasn't complaining. The pink lace barely covered anything, her puffy pussy lips clearly visible through the translucent fabric.

She unclasped her bra, and her perky tits bounced free, her nipples hard as diamonds. Harry had played with those perfect breasts many times now, but seeing them always made him want to suck and squeeze them until she was moaning and begging for more.

Finally, she hooked her thumbs into her panties and slid them down her long legs, revealing her cleanly shaven pussy. Her pink folds were already glistening with arousal, her clit peeking out from beneath its hood.

"Fuck, you're gorgeous," Harry breathed as she stepped into the bath, the warm water lapping at her thighs as she waded towards him.

"Don't try to distract me with compliments," Hermione said, though her voice wavered as she climbed into his lap, straddling him. "I'm still angry with you."

"Then why don't you punish me?" Harry suggested, his hands finding her hips beneath the water. "Ride my cock and show me what I've been missing."

Hermione's eyes flashed with determination. She reached down between them, gripping his thick shaft with one small hand, barely able to wrap her fingers around his girth. She positioned him at her entrance, her pussy lips spreading around his fat cockhead as she began to sink down.

"Oh Merlin," she whimpered as she took him inside her, her tight channel stretching to accommodate his size. "You're so bloody big, Harry."

"That's it," Harry encouraged, his fingers digging into her hips as she slowly impaled herself on his cock. "Take every inch like the good little slut you are."

The degrading words made her pussy clench around him, and she moaned, her head falling back as she finally bottomed out, her arse resting on his thighs with his cock buried completely inside her.

For a moment, they both just stayed like that, Hermione's walls fluttering around his length as she adjusted to the fullness. The warm water lapped at their bodies, creating gentle waves that splashed against the sides of the enormous tub.

Then Hermione began to move, lifting herself slowly before sinking back down. "Fuck," she gasped, establishing a rhythm. "This feels so good, Harry. Your cock fills me so perfectly."

Harry groaned, watching her tits bounce as she rode him. Her pussy was so tight, so wet, gripping him perfectly with each movement. She was picking up speed now, bouncing on his cock with increasing enthusiasm, the water splashing around them.

"That's it," Harry encouraged, his hands squeezing her arse cheeks as she rode him. "Fuck yourself on my cock, Hermione. Show me how much you've missed it."

Hermione moaned loudly, the sound echoing off the bathroom walls. She was really going for it now, slamming herself down on his cock with abandon, her pussy making obscene squelching noises. Her head was thrown back, her eyes closed, completely lost in the pleasure of riding him.

"So good," she panted, her nails digging into his shoulders. "Your cock feels so good in my pussy, Harry. I could ride you like this forever."

Harry watched her for another moment, enjoying the sight of her bouncing tits, the feel of her tight pussy gripping his cock. But then he remembered why she was here, what she'd come demanding. With a sharp smack to her arse that echoed through the bathroom, he brought her back to reality.

"Oi!" Hermione yelped, her eyes flying open. "What was that for?"

"You're forgetting why you're here," Harry reminded her, gripping her hips to still her movements. "You didn't storm in here demanding to ride my cock in your pussy. You wanted something else, didn't you?"

Hermione's eyes widened as she remembered, a fresh blush spreading across her cheeks. "Oh. Right. I... yes."

"So stop getting distracted and get in position," Harry said firmly.

Hermione scrambled to comply, positioning herself at the edge of the tub. She bent over the marble edge, her arse sticking up in the air, half out of the water. The cool air on her heated skin made her shiver, goosebumps rising along her thighs. Her plump arse cheeks were spread before him, her pink pussy lips swollen and leaking, and above that, her tight little arsehole winked at him, completely untouched and virgin.

"Fuck," Harry breathed, running his hands over her arse cheeks, squeezing and spreading them to get a better look. "Your arse is perfect, Hermione. I can't believe I waited this long."

"Less talking, more doing," Hermione demanded, though her voice shook slightly. "Show me what all the fuss is about."

Harry chuckled darkly, bringing one hand to her pussy, gathering her abundant juices on his fingers. "You need to relax," he instructed, bringing his slick fingers to her arsehole. "This is going to hurt at first."

"I can handle it," Hermione insisted stubbornly. "I'm not some delicate flower, Harry. I can take whatever you—OH!"

Her words cut off in a gasp as Harry pressed one finger against her tight hole, applying steady pressure until it breached her entrance. The resistance was incredible, her virgin arse squeezing his finger like a vice as he slowly worked it inside.

"Breathe," Harry instructed, his free hand rubbing soothing circles on her lower back. "You're so tight, Hermione. Fuck, your arse is gripping my finger like it never wants to let go."

Hermione whimpered, her hands gripping the marble edge so hard her knuckles turned white. "It feels... strange," she admitted, her voice small. "Not bad, just... full."

"Just wait," Harry promised, slowly pumping his finger in and out, gradually loosening her up. "It's going to feel incredible once you get used to it."

He added a second finger, scissoring them gently to stretch her further. Hermione moaned, the sound echoing beautifully off the bathroom's vaulted ceiling. The acoustics in here were perfect, making every gasp and whimper sound twice as loud.

"Harry," she whimpered as he worked a third finger inside her. "I think... I think I'm ready."

Harry wasn't so sure about that. Her arse was still incredibly tight, and his cock was much thicker than three fingers. But Hermione was determined, and he knew her well enough to know that once she'd made up her mind, there was no stopping her.

"Alright," he agreed, withdrawing his fingers. He gripped his cock, still slick with her pussy juices, and positioned himself at her entrance. "Remember, if it's too much, just tell me to stop."

"I won't need to," Hermione said stubbornly. "I can take it better than Astoria did."

Harry pressed forward, his fat cockhead meeting the resistance of her tight hole. He applied steady pressure, watching as her pink rosebud began to stretch and stretch, the ring of muscle straining to accommodate his girth.

"Oh fuck, oh fuck, oh FUCK!" Hermione chanted as his head finally popped past her sphincter, her arse swallowing him with an obscene squelch.

The sensation was incredible. Even tighter than Astoria had been, Hermione's virgin arse gripped him like a hot, velvet vice, the pressure almost painful in its intensity. Harry had to grit his teeth to keep from immediately coming, his balls already drawing up tight with the need to empty themselves inside her.

"Hermione," he groaned, his hands gripping her hips hard enough to bruise. "Fuck, you're so tight. Your arse is strangling my cock."

"Don't stop," Hermione gasped, her voice echoing loudly in the bathroom. "Keep going. I can take it all. I can take more than she did!"

Harry pushed deeper, feeding inch after inch of his thick cock into her impossibly tight arse. The water splashed around them as he moved, creating waves that lapped at their bodies. He could see Hermione's face in the reflection of the window, her mouth open in a silent scream, her eyes squeezed shut, her expression caught between pain and pleasure.

"That's it," Harry encouraged, managing to work half his length inside her. "You're doing so well. Taking my fat cock up your virgin arse like a good little slut."

The praise seemed to spur her on, and she pushed back against him, taking another few inches with a loud groan. The sound bounced off the walls, amplified by the bathroom's acoustics until it sounded like she was screaming.

"More," Hermione demanded breathlessly. "Give me all of it, Harry. Every... bloody... inch!"

Harry obliged, gripping her hips and pushing forward with steady pressure until finally, finally, his hips met her arse cheeks with a loud slap. He was buried completely inside her, his heavy balls resting against her dripping pussy, every inch of his massive cock sheathed in her impossibly tight arse.

"There," he panted, fighting the urge to move. "Every single inch, just like you wanted. How does it feel?"

"Full," Hermione whimpered, her whole body trembling. "So full. Merlin, Harry, I can feel you everywhere. In my arse, in my stomach, everywhere."

"You're doing so well," Harry praised, rubbing soothing circles on her lower back while her body adjusted to his size. "Taking my whole cock up your virgin arse like a proper slut. Knew you could handle it."

Hermione's breath hitched at the praise, her arse clenching around him. "I can take more than this," she insisted stubbornly, even though her voice shook. "I can take you fucking me properly. Hard."

That was all the invitation Harry needed. He pulled back slowly, his cock sliding out of her gripping arse until just the tip remained, before plunging back in with one hard thrust. Hermione screamed, the sound bouncing off every surface, loud enough that anyone in the corridor outside would hear.

"FUCK! HARRY!"

"That's it," Harry growled, establishing a rhythm, his hips slapping against her arse with wet smacks that echoed through the room. "Scream for me. Let everyone know how much you love taking my cock up your arse."

And scream she did. Hermione's cries of pleasure filled the bathroom, bouncing off the marble walls and vaulted ceiling until it sounded like a chorus of her voice all screaming at once. The acoustics made every moan, every whimper, every desperate plea for more sound twice as loud.

Harry pounded into her relentlessly, his cock pistoning in and out of her stretched arsehole with increasing speed. The water splashed violently around them, spilling over the edges of the tub and flooding the marble floor. But Harry didn't care about the mess. All he cared about was the feeling of Hermione's arse gripping his cock, the sound of her desperate screams, the sight of her perky tits bouncing beneath her as he fucked her.

"You love this, don't you?" Harry taunted, reaching around to find her clit with his fingers. "Love having your arse stretched around my fat cock. Bet you've been dreaming about this, haven't you? Jealous every time you heard I'd fucked someone else, wishing it was your holes I was filling."

"Yes!" Hermione sobbed, her pussy gushing as he rubbed her clit in tight circles. "Yes, I've been so jealous! Every time I heard about you fucking someone else, I'd go back to my room and finger myself, imagining it was me!"

The admission made Harry's cock throb, his balls churning with his impending orgasm. But he wasn't done teasing her yet.

"You know," he said conversationally, though his voice was strained, "Astoria took it better than this."

"WHAT?" Hermione's head snapped up, her eyes blazing even as her body shook with pleasure. "No she bloody didn't!"

"She did," Harry insisted, slamming into her harder to emphasise his point. "Her arse was already relaxed and ready. Yours is still fighting me, all tense and desperate. She knew how to take a proper fucking."

The challenge in his words ignited something primal in Hermione. Her competitive nature, already inflamed by jealousy and desire, reached a fever pitch that burned through her like wildfire. She refused to be bested, refused to let that Slytherin slut claim superiority in any arena, least of all in Harry's bed.

"Then make me come!" she demanded, pushing back against him with renewed vigour, her whole body a study in determination. "Make me come on your cock, Harry! Make me scream louder than she did! I'll show you who can really take it!"

Harry grinned wickedly, his fingers working her clit with expert precision while his other hand reached beneath her to squeeze her swinging tits, her breasts bouncing with the force of his thrusts. "That's more like it," he praised, his voice dripping with satisfaction. "Show me what my clever little bookworm can do. Show me you're worth all this trouble."

Hermione pushed back against him with frantic energy, meeting each of his thrusts with her own, taking his cock as deep as possible and refusing to yield an inch. The pain had faded entirely now, replaced by a pleasure so intense it bordered on overwhelming, her body finally adjusting to the incredible fullness of having his massive cock buried in her arse. The combination of sensations was absolutely maddening; his cock hammering relentlessly into her stretched hole, his fingers working her clit in tight, deliberate circles, his hand kneading her tit with rough possessiveness. It was all driving her towards a climax that promised to be absolutely explosive.

"Oh Merlin, oh Merlin, OH MERLIN!" Hermione chanted, her voice reaching a fever pitch. "Harry, I'm going to... I'm going to..."

"Come for me," Harry commanded, pinching her clit between his fingers. "Come on my cock like the desperate little slut you are. Show me you're better than Astoria."

The words pushed her over the edge. Hermione's orgasm hit her like a freight train, her whole body convulsing as pleasure exploded through her. Her arse clamped down on Harry's cock so hard he could barely move, the rippling contractions almost painful in their intensity.

"HARRY! OH FUCK, HARRY! YES, YES, YES!"

Her screams echoed through the bathroom, amplified by the acoustics until it sounded like the entire castle could hear her desperate cries of pleasure. Each moan bounced off the marble walls, creating a symphony of ecstasy that filled every corner of the cavernous space.

Harry gritted his teeth, fighting his own orgasm as Hermione's arse milked his cock. But the sensation was too much, the tight heat of her virgin hole combined with her desperate screams pushing him past the point of no return.

"Fuck, Hermione," he groaned, his hips stuttering as his orgasm approached. "I'm going to come. Gonna fill your tight little arse with my cum!"

"Yes!" Hermione sobbed, still trembling from her own climax. "Do it, Harry! Fill me up! Paint my insides white! Want to feel your cum deep in my arse!"

With a roar, Harry buried himself to the hilt one final time, his cock swelling even larger before erupting. Rope after rope of hot cum shot deep into Hermione's arse, flooding her insides with his seed. The sensation was incredible, the heat spreading through her body, marking her as his.

"Take it all," Harry groaned, grinding against her arse as his cock continued to pulse. "Every last drop in your perfect arse."

Hermione whimpered, her whole body shaking as she felt him filling her. The warmth spread through her belly, making her feel claimed and owned in the most primal way. This was different from when he came in her pussy. This felt deeper, more intimate somehow, like he was marking territory that no one else would ever touch.

They stayed like that for a long moment, both panting heavily, Harry's cock still buried in her arse, his cum slowly leaking out around his shaft. The water around them had gone still, the only sound their heavy breathing and the gentle drip of water from one of the taps.

"That was..." Hermione started, her voice hoarse from screaming.

"Incredible," Harry finished, slowly pulling out of her. His cock emerged with a wet pop, followed immediately by a stream of his cum. Hermione's arsehole gaped obscenely, unable to close after the pounding it had taken, his seed dripping steadily from her stretched hole down her thighs into the water.

Hermione turned around carefully, her legs shaky, and started to speak. "Harry, I just want you to know that I really can take it better than—"

The bathroom door suddenly opened with a loud creak.

Both Harry and Hermione froze, their eyes going wide as Daphne Greengrass walked in, her blonde hair swaying with each step, a towel draped over her arm. She stopped dead in her tracks as she took in the scene before her.

Harry, completely naked and still sporting a rock-hard cock covered in cum and Hermione's juices. Hermione, bent over the edge of the bath, her arse in the air, cum dripping steadily from her gaping arsehole down her thighs. The flooded bathroom floor. The scattered clothes.

For a moment, nobody moved. The only sound was the steady drip of cum from Hermione's well-fucked arse into the water below.

Then, slowly, a wicked smirk spread across Daphne's face.

"Well, well, well," she purred, her blue eyes sparkling with amusement as they traveled from Harry's cock to Hermione's gaping arse. "I came for a relaxing bath, but it seems I've walked into something far more interesting."
