"Well," Daphne said, her voice thick with post-orgasmic satisfaction as she lounged against the armrest of the sofa, "this is awkward."
Astoria couldn't respond. She couldn't do anything except sit there, impaled on Harry's cock, her virgin pussy stretched impossibly wide around his massive girth. Her whole body was trembling, aftershocks of her explosive orgasm still rippling through her, and every tiny movement sent fresh waves of sensation crashing through her overwhelmed nervous system.
Pansy and Tracey stood frozen before them, their mouths hanging open, their eyes fixed on the obscene tableau. Astoria Greengrass, the innocent one, the sensible one, the one their mother had sent to chaperone her wayward sister, was currently stuffed full of Harry Potter's legendary cock in the middle of Slughorn's Autumn Dinner.
"I... we... you..." Pansy stammered, her face cycling through approximately seventeen shades of red.
"She's..." Tracey tried, gesturing vaguely at where Astoria's dress was bunched around her waist, at where her thighs were spread obscenely wide across Harry's lap.
"Balls deep on Harry's cock?" Daphne supplied helpfully, examining her nails with exaggerated casualness. "Yes, we noticed. Would you like a closer look?"
That broke the spell. Pansy made a sound like a dying hippogriff, grabbed Tracey's arm, and the two of them fled into the crowd so fast they left their abandoned drinks shattered on the floor behind them.
Harry watched them go, his hands still resting on Astoria's trembling hips. His cock throbbed inside her, and she let out a whimper that made his balls tighten.
"They're going to tell everyone," Astoria whispered, her voice cracking with horror. "Everyone is going to know. Mother is going to find out. Father is going to murder me. I'm ruined. Completely and utterly ruined."
"Probably," Daphne agreed, still not looking particularly concerned. She shifted on the sofa, her own dress still rumpled from her earlier activities, her cleavage glistening with sweat. "But look on the bright side, Astoria. At least you're ruined by the best cock in Britain."
"This isn't funny, Daphne!"
"It's a little funny." Daphne's lips curled into an amused smile. "You came here to stop me from doing anything improper, and now you're the one sitting on Harry's cock in front of half our year. Mother's going to have a stroke."
Astoria's pussy clenched around Harry at her sister's words, and she let out an involuntary moan that made her face burn even hotter. Her body was betraying her, responding to every pulse and throb of the massive cock buried inside her, sending pleasure signals to her brain that she desperately wanted to ignore.
"I need to... I have to..." Astoria braced her hands on Harry's knees and tried to lift herself up.
She made it approximately two inches before her body gave out.
Harry watched, fascinated, as Astoria sank back down onto his cock with a wet sound that echoed obscenely in the alcove. Her eyes rolled back, her mouth falling open in a silent gasp, her tits heaving against the straining fabric of her dress.
"Oh Merlin," she breathed, her voice trembling. "Oh no. Oh no, I can't... I can't get up..."
"You have to relax, Astoria," Daphne said, finally showing some interest in her sister's predicament. She shifted closer, her own tits brushing against Astoria's arm as she leaned in to observe. "You're clenching too hard. Let his fat cock stretch you properly."
"I am NOT clenching!" Astoria protested, even as her pussy tightened around Harry again. "And I am NOT enjoying this! This is... this is just... I only did this to hide his... his..."
"Cock," Harry supplied, his voice rough with arousal. "You stuffed your virgin pussy full of my cock to hide it from your sister's friends."
Astoria whimpered. The crude words shouldn't have affected her, shouldn't have made her pussy flutter and clench, shouldn't have made her nipples stiffen against the tight emerald silk of her dress. But they did. Merlin help her, they did.
"I was panicking," she whispered, trying to lift herself again. "It was the only thing I could think of. Daphne told me to do something, and I just... I saw what she did earlier, and I..."
Her voice trailed off into a moan as she sank back down, her body refusing to cooperate with her increasingly desperate attempts to escape. Every time she tried to lift off, Harry's cock dragged against spots inside her that she hadn't known existed, sending jolts of pleasure through her that made her legs give out.
"This is hopeless," Daphne sighed, though she didn't sound particularly disappointed. If anything, she sounded entertained. "You're going to be stuck on his cock forever at this rate."
"Don't say that!"
"What? It's true. You keep trying to pull off, and your body keeps pulling you back down. It's like his cock was made for you." Daphne's hand came up to cup Astoria's cheek, turning her sister's face towards her. "Just accept it, Astoria. Accept that you need to be properly fucked before you can leave."
Astoria's eyes widened. "I am NOT going to... to..."
But even as she protested, her hips had started moving. Small, unconscious rolls that made Harry groan and grip her waist tighter. Her body knew what it wanted, even if her mind was still catching up.
"You're already doing it," Daphne pointed out, her voice dropping to a sultry purr. "Look at you. Rocking back and forth on his cock like a bitch in heat."
"I'm not... I'm just trying to..." Astoria's protest dissolved into a whimper as she ground down particularly hard. "Oh fuck. Oh fuck, it feels so..."
"Good?" Daphne finished, her smile widening. "Of course it does. It's the best cock you'll ever have, little sister. Trust me on that."
Harry's hands tightened on Astoria's hips, helping to guide her movements. Her dress had ridden up completely now, bunched around her waist like a silken belt, leaving her entire lower half exposed. Her arse, round and perfect and pale, bounced slightly with each rock of her hips. Her pussy, stretched obscenely wide around his shaft, glistened with arousal that dripped down onto his balls.
She was gorgeous. Fucking gorgeous. Her blonde hair, which had been pinned up elegantly at the start of the evening, was coming loose in dishevelled waves around her flushed face. Her tits strained against her dress, the fabric pulled so tight that he could see the outline of her stiff nipples pressing through the silk. Her lips, glossy and pink, were parted in a continuous stream of soft moans and whimpers.
"That's it," Harry murmured, thrusting up slightly to meet her grinding hips. "Just like that. Let yourself feel it."
"I don't... I'm not..." Astoria's protests were becoming less and less coherent. "This is just... just because I'm stuck... I'm not actually..."
"Not actually what?" Harry thrust up again, harder this time, and Astoria cried out, her back arching. "Not actually enjoying my cock splitting your tight little pussy open?"
"Stop saying things like that!" But her hips moved faster, her grinding becoming more purposeful. "It's vulgar and... and... oh Merlin, right there... don't stop..."
Daphne laughed, low and throaty. "I think you've broken her, Harry. The proper Greengrass sister, reduced to begging for cock."
"I'm not begging!" Astoria gasped, even as she started bouncing properly in his lap. "I'm just... I'm just..."
She gave up on words entirely, throwing her head back as she began to ride him in earnest. Her tits bounced wildly against the straining fabric of her dress, threatening to spill free with each movement. Her moans grew louder, less restrained, echoing through the alcove with complete disregard for the party continuing just feet away.
Harry watched, mesmerised, as the innocent younger Greengrass transformed before his eyes. Every bounce brought her dress closer to catastrophic failure, the neckline straining lower and lower until finally, inevitably, it gave up the fight entirely.
Her tits sprang free with a bounce that made Harry's cock throb. They were magnificent. Slightly smaller than Daphne's but perfectly shaped, pale and creamy with pink nipples that stood stiff and proud in the cool air. They swayed and jiggled with each movement, rippling like waves as she rode him harder and faster.
"There we go," Daphne purred approvingly, reaching out to cup one of her sister's freed breasts. "Much better. Your tits are gorgeous, Astoria. You should show them off more often."
"Don't... don't touch..." But Astoria didn't push her sister's hand away. If anything, she leaned into the touch, her moans deepening as Daphne's fingers found her nipple and pinched.
Harry was in absolute heaven. Astoria's virgin cunt was impossibly tight around him, gripping and squeezing with each bounce, her walls rippling and fluttering as she worked herself towards another orgasm. Her tits bounced hypnotically before him, one being fondled by her sister while the other swayed freely, begging for attention.
He reached up and claimed it, palming the soft flesh, rolling her stiff nipple between his fingers. Astoria cried out, her rhythm faltering, her pussy clenching hard around his cock.
"Fuck!" she gasped, a word he was fairly certain had never crossed her lips before tonight. "That's... oh Merlin, that's..."
"Good?" Harry thrust up into her, hard, making her tits ripple. "Amazing? Everything you never knew you needed?"
"Yes!" Astoria wailed, her composure shattering completely. "Yes, yes, yes! Don't stop! Please don't stop!"
She was bouncing wildly now, her arse slapping against his thighs with each downward thrust, her tits doing waves with the force of her movements. The alcove was filled with the wet sounds of their coupling, with her increasingly loud moans, with the creak of the sofa beneath them.
And they were drawing attention.
Harry could see people glancing their way, could see the shocked expressions, the scandalised whispers, the hands flying to cover mouths. Slughorn's Autumn Dinner was getting a show it would never forget.
But Harry was beyond caring. Pansy and Tracey were already spreading the news. By tomorrow, everyone would know. So why not give them something truly spectacular to gossip about?
He made a decision.
In one smooth motion, Harry stood up, his hands hooking under Astoria's knees. She shrieked in surprise as she was lifted, her back pressed against his chest, her legs spread wide and held up by his grip. His cock was still buried inside her, and from this angle, from this position, their coupling was displayed to anyone who cared to look.
"Harry!" Astoria squeaked, her voice high with panic. "What are you... everyone can see... put me down!"
"No," Harry said simply, and began to fuck her properly.
His cock pistoned in and out of her exposed pussy, jackhammering into her tight cunt with a force that made her whole body shake. Her tits bounced wildly, freed from her dress, rippling and swaying with each powerful thrust. Her legs kicked helplessly in the air, her high heels dangling from her feet, her entire body at his mercy.
He was using her like a sleeve. Like a doll. Holding her up with ease, his hips driving forward again and again, his cock splitting her open with relentless force. And Astoria...
Astoria was lost.
"Oh fuck!" she screamed, her voice ringing through the party. "Oh fuck, oh fuck, oh fuck! Don't stop! Please don't stop! Your cock... your big fucking cock... it's so deep... I can feel it in my stomach... don't stop fucking me... please... please!"
The proper sister. The innocent one. The chaperone. Screaming obscenities while being fucked in front of half of Hogwarts' elite.
Daphne had settled back on the sofa, her own dress hiked up, her fingers buried in her pussy as she watched her sister get absolutely ruined. "That's it, Astoria!" she called encouragingly, her voice breathy with her own building pleasure. "Take his cock! Take every fucking inch!"
People were openly staring now. Harry could see Slughorn in the distance, his face pale with shock, his hand frozen halfway to a glass of mead. He could see other professors, other students, all watching the spectacle with expressions ranging from horror to arousal to something in between.
He didn't care. All he cared about was the tight, wet heat of Astoria's pussy around his cock, the sound of her whorish moans, the way her tits bounced and rippled with each thrust, the way she was begging him, actually begging him, to keep fucking her.
"Please!" Astoria wailed, her hands reaching back to grip his hair. "Please, I'm so close! I'm going to... I need... Harry, please!"
"Please what?" Harry growled, his hips never slowing. "Tell me what you need, Astoria."
"Your cum!" she screamed, all pretence of propriety abandoned. "I need your cum! Fill me up! Please, Harry, I'm begging you, pump me full of your seed!"
Those words, from those innocent lips, were almost enough to push him over the edge right there. But Harry held on, his cock driving into her again and again, building her higher and higher until...
Astoria shattered.
Her scream echoed through the entire room as she came harder than she'd ever come in her life. Her pussy clamped down on his cock like a vice, rippling and squeezing, milking him with desperate force. Her whole body convulsed in his grip, her tits bouncing wildly, her legs shaking uncontrollably.
And Harry finally let go.
He came with a groan, his cock pulsing inside her, filling her virgin womb with rope after rope of hot, thick cum. He pumped into her again and again, emptying his balls completely, marking her, claiming her, making her his.
On the sofa, Daphne cried out as she brought herself to completion, her fingers working furiously between her legs, her eyes locked on the sight of her sister being fill with her man's cum.
For a long moment, the three of them existed in a bubble of pure, post-orgasmic bliss. Harry's cock twitched inside Astoria, still pumping the last drops of his seed into her depths. Astoria hung limp in his grip, her breathing ragged, her body still trembling with aftershocks.
And then Astoria's eyes snapped open.
"Oh no," she whispered, her voice suddenly clear and sharp with dawning horror. "Oh no. Oh no, oh no, oh no."
Harry carefully lowered her back to the sofa, his softening cock slipping out of her with a wet sound. Cum immediately began to leak from her well-fucked pussy, trailing down her thighs in thick, white rivulets.
"What is it?" he asked, still somewhat dazed from the force of his orgasm.
"I'm not..." Astoria's hands flew to her stomach, her face draining of colour. "I'm not on the contraceptive potion. I never... I wasn't planning on... oh Merlin, I'm not on the potion!"
Beside them, Daphne froze mid-stretch.
"You're... what?" Daphne's voice had taken on a dangerous edge.
"The contraceptive potion!" Astoria's voice was rising in pitch, approaching hysteria. "I didn't take it! Why would I? I wasn't planning on having sex tonight! I was supposed to be chaperoning you, not getting... not getting..."
"Bred like a bitch?" Daphne supplied, but there was no amusement in her voice now. Her eyes had narrowed, her jaw tightening.
"Daphne, this is serious!" Astoria clutched at her sister's arm. "What if I'm... what if Harry's..."
"What if Harry's baby is growing inside you right now?" Daphne finished, her voice deceptively calm. Too calm. "What if my little sister, the one who was supposed to stop me from doing anything improper, is carrying Harry Potter's child?"
Astoria flinched at the words, tears gathering in the corners of her eyes. "I didn't mean for this to happen! It was an accident!"
"An accident," Daphne repeated flatly. "You accidentally sat on his cock. You accidentally bounced up and down until you came. You accidentally begged him to fill you up. And now you're accidentally going to give him his first heir before I do?"
Harry blinked, suddenly realising the direction this conversation had taken. "Wait, Daphne, are you... are you jealous?"
Daphne's head snapped towards him, her green eyes blazing with an intensity that made his spent cock twitch. "I have been taking his cum for weeks," she said, her voice tight with barely suppressed outrage. "Weeks! I've been swallowing it, wearing it, letting him pump it into my pussy and my arse. And the whole time, I've been on the potion like a responsible slut!"
"You're... angry that you didn't get pregnant?" Astoria asked, bewildered even through her panic.
"I'm angry that you might have beaten me to it!" Daphne jabbed a finger at her sister's cum-leaking pussy. "I was supposed to be the one! I was supposed to give him his first! And now you, the chaperone, the good girl, might be carrying his baby because you couldn't keep your virgin pussy off his cock for five bloody minutes!"
Harry sat back, watching the Greengrass sisters argue over who should be carrying his child. Around them, the party had devolved into chaos. People were whispering frantically, pointing at the alcove, several had fled entirely. Slughorn looked like he might faint.
But Harry couldn't bring himself to care about any of that. His cock was already stirring again, responding to the sight of two gorgeous, thoroughly debauched witches fighting over his seed.
"This isn't over," Daphne declared, rising from the sofa with as much dignity as she could muster given that her dress was still dishevelled and her pussy was clearly soaked. "We're going to see Madam Pomfrey right now. And if you're pregnant..." She leaned in close to her sister, her voice dropping to a threatening whisper. "Then I'm going off the potion tonight. And I'm going to ride Harry's cock until he puts a baby in me."
Astoria's eyes went wide. "You can't be serious!"
"Watch me."
The two sisters stared at each other, the tension crackling between them like lightning. Harry's cock throbbed, now fully hard again, jutting up proudly from his lap like a monument to the chaos it had caused.
Both Greengrass sisters noticed at the same moment. Both of their eyes dropped to his renewed erection. Both of their cheeks flushed.
The rivalry that sparked in their gazes promised that Harry's immediate future was going to be very, very exhausting.
And he couldn't wait.
