Harry watched with no small amusement as Astoria tugged at his hand fiercely as she strode down the corridor. She was a witch on a mission, and she wasn't even looking behind her to see if Daphne was bothering to follow them or not; her eyes were too busy scanning around, looking for another room they could take over since Draco wasn't worthy of seeing her body.

Glancing behind himself, Harry spotted Daphne trailing behind him. It was so strange to see her acting shy. She was lingering several metres back, as though anyone they came across might somehow be able to immediately understand what was about to happen if they spotted Daphne walking alongside Harry and Astoria. Throughout the entire walk, Daphne never met Harry's gaze even once.

For a moment, Harry wondered if Astoria and Daphne had switched personalities. Normally, Astoria was the quieter one in public—she could be quite vocal and spunky when the two of them were alone—and Daphne was the one who dominated the social landscape with her commanding presence. Now, Astoria was acting as the centre of attention while Daphne was lingering at the back.

"Here," Astoria declared as she reached for a door handle.

They were still far away from the main section of the dungeons in a corridor Harry didn't recognise. Astoria practically threw the door open and pulled Harry inside, only holding the door open long enough for Daphne to slip in before she slammed it shut.

"Wards," Astoria practically barked at her sister as she illuminated the room by conjuring several Bluebell Flames that filled glass jars dangling from the rafters above.

With the new light source, Harry quickly recognised that they were in an old, unused classroom. There were perhaps fifteen desks in all, though most of them had been pushed back against the walls. Four of them had been pressed together in the centre of the classroom to form a large worktop. There were four crummy, half-broken chairs around them.

Moving with impressive speed, Astoria banished the broken chairs away and conjured a pair of plush, dark-green armchairs beside each other, both facing the desks. Then, another flick of her wand vanished all of the dust off of the desks, floor, and surrounding area.

Daphne had just finished putting up a number of privacy, silencing, locking, and alarm spells around the room and the door when Astoria finished too. Astoria's eyes raked over Harry's body hungrily, but before she could get to him, she had to deal with her sister first.

"I promised that you could watch," Astoria grunted as she grabbed Daphne's sleeve. Daphne had a look of surprise cross her face as Astoria pulled her over to one of the armchairs and shoved her down into it. "So watch," Astoria told her sister. "I can't wait another second."

Astoria immediately crouched down and stuck her hands beneath her skirt. When she stood back up, Harry spotted her panties around her ankles. She stepped out of them and walked right up to the edge of the four desks so that her hips were pressed up against them. Then, she bent over, flipping up her skirt as she went.

A thrill shot through Harry as he took in Astoria's arse. Despite having just been brought to completion by her sweet lips, his cock was already rapidly hardening inside of his trousers at just the briefest glance at her. Her milky-white skin and round arse were a sight to behold. Those two bubbly globes just begged to be grabbed onto, and the gap between her thighs showed off her dripping-wet, pink entrance.

"Well?" Astoria prompted Harry with a raised eyebrow as she looked at him over her shoulder. "Didn't I say how I couldn't wait another second?"

Harry quivered at her authoritative tone. He didn't bother to look at Daphne's reaction as her sister literally begged him to fuck her; he just walked up behind Astoria as he fiddled with his zipper.

Harry's cock was still a bit wet from Astoria's blowjob, but he didn't really need any additional lubrication given how wet she was. When he angled his cock towards her puffy pussy, her lips parted easily around his head and guided him inside of her. He slipped into the tight heat with an emphatic moan and kept pushing forward.

You would swear that Astoria came with the sounds that left her lips. She cried out in pleasure as Harry's cock filled her aching pussy, stretching out her walls. Harry could feel it pulsing around him, squeezing him tantalisingly as he probed as deep as he could inside of her. She felt like a furnace around him, and he was more than happy to melt in a state of pure bliss with her.

"Fuck," Astoria moaned as his hips made contact with her arse. "That's what I needed. There really is nothing like it."

Harry's cock jumped inside of her, and that only made her moan louder. "I'm always happy to give it to my good girl anytime she asks for it," he murmured seductively as he grabbed onto her hips. Her walls clenched up tight around him at his little nickname for her. It was a recent discovery that she desperately loved being called his good girl, so he did his best to use it to maximum effect whenever they were together.

"Then don't hold back!" Astoria cried out as she pushed her arse back against him. She wiggled it back, trying to get every last inch of him inside of her pussy. "Fuck me hard!"

Harry's grip on her hips tightened as he pulled his hips back. "Anything for my good girl!" He shouted as he slammed forward.

Astoria screamed as Harry's cock rammed inside of her. Her body jostled forward on the desks, but Harry kept her locked in place as he fucked her. He was merciless as he pounded her pussy fast and hard with his cock, trying so desperately to give her exactly what she had asked for.

"Yes!" Astoria shouted. "Yes! Yes! YES!" Her voice turned into a squeal when Harry rammed forward particularly hard and his balls smacked off of her engorged clit. Her hands searched for anything they could grab onto, but she couldn't reach across to the other side of the desks.

Suddenly, a light enveloped both of Astoria's hands, and they became locked in place on top of the desk; it was like her palms had been glued to the desks.

Harry glanced beside him to see Daphne deftly stowing her wand away inside of her robes. She was still sitting in the armchair that Astoria had pushed her down into, but she had one of her legs over the armrest. The hem of her skirt was high up on her thigh, but her underwear was still obscured from Harry's sight.

Daphne met his gaze evenly, challenging him to say anything about her watching them. Her cheeks were flushed and her breathing a little heavier than normal, but otherwise she seemed fine. Truthfully, Harry didn't care if Daphne was watching him and Astoria or not. He looked away and returned to what he really cared about: his beautiful girlfriend.

With his cock perpetually slamming in and out of Astoria's pussy, Harry was quickly losing himself to a haze of pleasure. The desks beneath her started to creak in time with the sound of his hips smacking off of her arse. It all felt just too damn perfect to be real.

"You feel so good," Harry groaned. He let go of one of her hips and smacked her arsecheek.

Astoria squealed in delight. "I wish you could fuck me like this forever. Come on, really give it to me!"

Harry gasped and caught himself as he nearly came inside of Astoria from her naughty words. He had to tense his thighs and still himself inside of her pussy for a few seconds to regain his composure. "Nearly finished me off there," he chuckled.

"I'll get you eventually," Astoria winked over her shoulder. "I expect to be nice and filled with your cum by the end of this."

Harry's toes curled in his shoes, and he couldn't help but rock his hips against her arse. That motion spurred him on for more as the pleasure from his cock being surrounded by her tight, wet, hot, writhing walls was just too much to let linger for long.

Harry planted his hands on the edge of the desk on either side of Astoria and leaned over her back as he returned to fucking her hard and fast. This new angle really let him make even more powerful thrusts into her. Astoria's entire body kept rocking forward as she moaned wantonly, and she even ended up sliding forward a bit onto the desks. Since her hands were magically glued to the desks, her feet had no choice but to lift off of the ground as Harry kept pounding into her.

"More!" Astoria moaned, despite how hard Harry was already giving it to her.

Harry chuckled. "Someone's developed quite the appetite," he teased her.

"Yes, I have," Astoria groaned as his cock filled her pussy again. Her pussy was pulsing more frequently around him.

"So have I," Harry told her as he spanked her arse again.

As Harry spanked Astoria, he swore that he heard a moan. Only . . . it wasn't a moan from him or Astoria.

Without pausing the motion of his hips, Harry glanced over at Daphne again. She didn't look much different than before other than the fact that her eyes were glued onto Harry's cock as it plunged into Astoria's pussy. He could see the rise and fall of her chest as watched, entranced.

When she finally noticed him looking at her, she suddenly shifted in her seat awkwardly. That moved her skirt up high enough for Harry to see the green silk panties she was wearing and the massive damp spot on the front of them. She quickly moved to readjust her skirt to cover herself. It may have been a trick of the light, but Harry swore that he saw a little bit of wetness on a couple of her fingers.

Astoria's pussy tightened up hard around Harry's cock, forcing his gaze back to his girlfriend. She was panting hard as he kept fucking her, but it was getting hard to move with her walls gripping his cock so firmly.

"Is my good girl getting close to cumming?" He murmured to her.

"Uh huh," Astoria replied in a high-pitched sound. "Fuck, your cock is incredible. I'm so close, Harry, just a little bit more!"

Merlin, there was nothing quite so hot as his girlfriend talking dirty to him. His cock rammed in and out of her pussy just as hard as before, but her fluttering walls and filthy words were bringing him so close to the edge. Harry moaned loudly; he couldn't help it with how good he felt.

"That's it!" Astoria cried out. Her pussy spasmed again, and when his balls smacked off of her clit, she screamed in pleasure. "I'm cumming!"

Suddenly, Astoria's entire body began to shake beneath Harry. Her orgasm hit her hard like a wave, making her go cross eyed as the pleasure of being fucked so good by her boyfriend left her mind blank for a moment.

Harry didn't stop fucking Astoria when her orgasm hit; instead, he kept at it, knowing that he was terribly close to finishing too. Despite how tight she got, Harry kept making long, powerful thrusts as deep as he could into her pussy, relishing in the sensations of her walls pushing in against every inch of his cock.

A slight whimper from Daphne's lips caught his attention again, and he glanced over just as she was smoothing out her skirt. Her face was red with embarrassment, but her gaze was locked onto Astoria's jiggling arse as Harry pounded into her pussy.

Harry let go of the table and instead grabbed onto Astoria's arsecheeks as he made his final thrusts. Her soft flesh filled the gaps in between his fingers, and Astoria moaned at being manhandled by him. She was still in the throes of her orgasm when he came inside of her, and the sudden burst of his hot cum sent another wave of pleasure coursing through her body.

"Fuck!" Harry groaned as he released his seed inside of his girlfriend. Spurt after spurt shot out, filling her up until there wasn't any space left and his cum started to drip out of her around his cock. He bent over Astoria completely so that his chest was against her back. He panted in her ear and placed a tender kiss on her cheek as he gave a couple tiny thrusts inside of her, pushing out that last bit of cum still inside of him.

Once they were both satisfied, Harry gave Astoria one more kiss on her cheek and started to stand up. Just as he was about to pull out of her, a flash of light illuminated Astoria's hands, releasing the sticking charm that had been on them. She quickly reached back and grabbed his wrists before pushing back with her arse. Astoria giggled as she guided Harry back to the second chair she had conjured, making sure that he stayed inside of her the entire time.

Harry fell back into the vacant seat, and Astoria fell with him onto his lap. Harry groaned as her pussy clenched snugly around his cock.

Astoria flipped her skirt back down, covering up where her and Harry's bodies were joined, and looked up at her sister. Daphne had returned to a normal sitting position and the blush had mostly faded from her face.

"There, you got to watch us fuck," Astoria said bluntly to Daphne. "I told you before that I like Harry and that he's good to me."

Daphne looked a little uncomfortable at Astoria's words. Her lips were pressed into a thin line and she was avoiding looking directly at either of them, but she still gave a slight nod in acknowledgement.

Astoria gave a small sight and cuddled closer against Harry's torso. He could feel his cum leaking out of her pussy around his cock, staining his trousers, but neither of them seemed to want to break the close physical contact that they had with each other. Harry wrapped his arms around Astoria's waist and hugged her against him as he let his body relax.

Suddenly, Daphne stood up and walked to the door. Astoria opened her mouth like she wanted to say something, but she closed it a moment later and looked away from her sister.

When Daphne cracked the door open to leave, she glanced back at Harry and Astoria. The look barely lasted a second, but Harry saw the wistful look in her eyes. It seemed so raw and filled with emotion that Harry thought that she might actually close the door and come back, but then that familiar mask slipped over Daphne's face and she stepped out into the corridor.

As the door closed gently behind Daphne's retreating form, Harry glanced back down to Astoria. "Alright, can you tell me what that was all about now?" He asked her. First, she gave him a blowjob in front of Daphne and Draco, and then she begged him to fuck her in front of Daphne. In their short time they'd been together, Astoria had never once suggested doing anything like that. Hell, given the Fleur situation, Harry figured that Astoria would be too jealous to ever let someone else watch them like this.

Astoria squirmed in his lap as she adjusted herself to look up at him. Harry's heart immediately started to pound in his chest when he saw the tears in her eyes.

"Astoria," he said concernedly as he brought his hand up to her cheek. A million different ideas ran through his mind over why she was crying. Did she regret what they did in front of Daphne? Did something happen before she came to his aid with Draco? Was there something else going on that he didn't know about? "What's wrong? Talk to me, please."

"Sorry," she murmured, wiping at her eyes. "This was all just a lot."

Harry felt a tinge of regret shoot through him. "I'm sorry if I was too rough—"

"No," Astoria quickly interrupted him before he could go down a line of thought that she didn't intend. "It wasn't you; you were perfect."

"What was it then?" Harry asked as he gave her a gentle squeeze with his arms.

"It's going to be a lot to explain," Astoria grimaced.

Harry smiled encouragingly at her. "I might be a bit thick, but I'll try to keep up."

Astoria laughed a little at that and rested the side of her head against his shoulder.

"Before we went to Hogwarts, Daphne was my best friend," Astoria began to explain. She let out another laugh as she glanced wistfully up at the ceiling. "I used to call her Daffy when I was too young to pronounce Daphne; it was what I called her for years. We did everything together: playing in the pond behind our house, chasing geese around our front lawn, we even had our own garden where we planted whatever we wanted in it and took care of it together. Everything was great for a while, but our relationship started to strain once we were both teenagers."

"It started a few days after I turned thirteen. Mum and Dad sat us down and told us that we couldn't share a room anymore. Our room was big, so it wasn't like we didn't have our own space or privacy, but my parents insisted. Daphne and I argued and yelled, but we ended up with our own rooms in different parts of the manor after our parents caught us sneaking into each other's rooms at night."

"From then on, things became different. Mum and Dad would stop us from spending as much time together. We got separate tutors to take over our studies, and our schedules were changed so that there was less overlap between them. When Daphne turned sixteen a few months later, Mum and Dad started taking her out of the house with them on trips."

The way she said 'trips' told Harry that they weren't the nice kind of family vacations he had always dreamed of taking whenever he saw advertisements on the telly as a kid.

"I didn't know it at the time, but I eventually learnt that they were taking her out to meet potential suitors," Astoria sighed sadly. "They went all around Europe visiting people and showing her off to anyone with a son roughly her age. She became really distant from me then. I think she was upset that I didn't have to do all of those things that she was doing. Our parents sort of left me to do whatever I felt like, but Daphne had her every move watched closely by them."

That sounded difficult. Growing up, Harry's aunt and uncle frequently switched between critical oversight of everything he did—namely his chores and anything he did that had any connection to Dudley, like schoolwork—but then they'd purposefully ignore him the rest of the time. He had chafed under both types of 'parenting' for different reasons. The strict oversight had left him feeling incompetent and like he'd never measure up to their goals, and the times he was ignored had left him feeling lonely and unloved. It must have been just as difficult for Daphne to go to so many wonderful places in Europe but never be able to experience them freely.

"By the time she went off to Hogwarts, Daphne had started to be more outwardly hostile towards me. At first I thought it was just like the normal fights we used to have every once and a while, but she started to begrudge me for the freedom I had. It only got worse when I arrived at Hogwarts and had to deal with all of the drama in Slytherin; Daphne left me to deal with it on my own."

Astoria sniffled a little, and Harry held her tighter. "I know my parents were always harder on her since she's the first born. The Greengrass family is matriarchal, so everything we own is passed down through the eldest daughter. They want to make sure that she's ready for that, but it's caused a massive rift between us."

"Things got worse with the Yule Ball," Astoria said sadly. "When she heard I was going with you, she came to visit me. It was the first time she'd ever come to visit my room at Hogwarts, and all she did was yell at me about how I was making a massive mistake that was going to cost us everything. She said that you were just like Malfoy and that you'd hurt me, but I knew that wasn't true. She tried to ban me from going with you. We got into a big argument about it."

"I'm sorry if I—"

"It's not your fault," Astoria stated firmly, poking Harry's chest with her finger. "People in Slytherin are idiots if they think that you're anything but a wonderful and kind man. I told Daphne as much, but it didn't seem to sway her. Looking back on it, I think she was trying to protect me like our parents protect her. They make sure that none of the suitors she meets do anything untoward to her, and they make sure that she never gets too close to any of them. I think she wanted the same thing for me."

"That's no way to live," Harry murmured sadly. Being isolated from everyone like that would be miserable. Any genuine connections that Daphne could form were stopped before they could blossom.

"That's why I wanted to prove to her that you are so wonderful," Astoria explained. "You're everything I could have ever wished for in a boyfriend, and I want her to know that I'm truly happy being with you. I don't know how far our relationship will go, but I know that you wouldn't do anything to sabotage it like Daphne thinks will happen. Plus, I want Daphne to see that she can have someone like you too if she just asserted herself a bit more. I wish she didn't care how much our parents thought about her and her actions."

It felt so heartwarming to hear that Astoria thought he was so perfect. "You're everything I ever wanted in a girlfriend too," he told her. "You're so smart and beautiful and an absolute minx in the bedroom—"

Astoria hit his chest but she was laughing regardless.

"—and I'm glad that you care so much about your sister," Harry smiled at her. "You know, I don't think that I ever mentioned that Daphne watched us before when we were in the Prefect's Bath."

"She told me," Astoria replied. A burst of giggles left her mouth. "She tried to suggest that you had bewitched me into having sex with you. She was all ready to go to the Ministry to try and get you arrested when I told her that I was the one who initiated sex with you in the first place back at the Yule Ball."

Harry snorted. "And today was your way of proving that?"

"Something like that," Astoria answered with a coy grin. "Mostly I think I was just trying to show her how good independence could be. I've tried to convince her to go against our parents before and make her own choices for herself, but she's always refused."

"So you're basically telling your sister to go shag some guy?"

"Pretty much. I figure if she acts like she's got a pole up her arse, maybe one in her twat would balance her out."

The shocked look on Harry's face sent Astoria into another fit of giggles.

"Not the worst bit of logic I've had," she joked in between fits. She turned in his lap and planted her knees on either side of his hips. She raised herself up then, making Harry's cock finally slip out of her, and planted a kiss on his lips. "After all, you did help me mellow out a bit."

"More than a bit I'd say," Harry said before he kissed her. "Where did my quiet, innocent woman I spied on in the library run off to?"

Astoria smiled at him. "She's still here," she assured him. "She just found out how good a little bit of naughty fun can be too."

They cuddled together there for a while, giving each other little kisses and relishing in the warmth of each other's bodies. Today had been a lot, and Harry was thoroughly exhausted. He knew that at some point he was going to have to come up with a plan to help Daphne. Astoria cared so much about her sister; it didn't seem right to leave Daphne in a situation that she wasn't happy in. Maybe he and Astoria could work on something together, but that would have to wait for another day.

For now, all Harry wanted to do was cuddle with his girlfriend.
