"Tonks?" Harry mumbled, staring at the metamorph.

"Wotcher, Harry!" she said, smirking at him and waving cheerfully. "Nice catch yesterday."

He knew he wasn't in any actual trouble here; not with her. They'd had enough fun together throughout the term that there was no way Tonks would be turning him in for fucking in the Gryffindor common room. He was simply surprised to see her.

"What're you doing here?" he asked.

"More importantly, how did you break through my charms?!" Romilda said. She didn't seem embarrassed about being caught with Harry's cum in her hair; that someone had broken through her magic was a greater concern for her. "Even if the Fat Lady let you in, the magic should have convinced you that you needed to get back to bed as soon as you stepped foot into the common room!"

"Yes, I'm well aware of what you intended," Tonks said, rolling her eyes. "But as I said, you're not as clever as you think you are. You did a neat little bit of spellwork, I'll give you that, but I'm a trained auror. You might have been able to keep other students away, but experienced wizards and witches like me can see through stuff like that in our sleep."

Romilda deflated, but her friends seemed more concerned about what might happen to them now. While Tonks wasn't officially a teacher at Hogwarts, she'd taken up regular residence in Hogsmeade and was given all the powers of her teacher since she oversaw so many prefect patrols. This meant that she had the power to deduct house points and even assign detentions.

"Are we in trouble?" Ann asked meekly.

"Nope," Tonks said, shaking her head carelessly. "You're all Gryffindors, and you're all in Gryffindor Tower. Long as nobody's doing anything to anyone against their will, I don't really give a toss what happens in here." Ann sighed in relief, and Jessie laughed and gave Romilda a peace sign. Miranda bent down to give Ann a hug, and Tonks whistled.

"Bloody hell, Miranda," the metamorph said. "Anyone ever tell you you've got one hell of an arse?"

--

"So what's this all about?" Harry asked as he and Tonks left Gryffindor Tower behind. "Why'd you come and get me?" He didn't bother asking how she'd known where he was; he knew she'd just give him some vague answer about aurors having their trade secrets.

"I came for a favor," she said. "I'm supposed to be with that little snot Astoria Greengrass in her detention tonight, but I've got a scheduling conflict. The department's got a lead on the bloke who's been trying to stir up the anti-muggle stuff again, and we're doing a raid tonight. They need me, and it's a hell of a lot more important than sitting there and watching Astoriawrite lines for two hours."

"No argument here," he said. "But what does this have to do with me?"

"I'm hoping you can fill in for me," she said. He raised his eyebrows, and she shrugged helplessly. "McGonagall's holding a staff meeting tonight, so none of the other teachers can do it. She said in extreme circumstances like this the Head Boy or Head Girl can fill in. There's obviously a conflict of interest with the Head Girl being her older sister and all, so you're really my only option."

Harry had a feeling Astoriawould actually get off lighter with him than she would with Daphne, even if it might not seem that way to an outsider. But he could see that Tonks was in a bind here, and he was her only way out.

"Please?" she asked. She made her eyes so big, round and expressive that she looked more like an animated character than a real person. "I'll owe you a favor. A big one. You can cash it in whenever and wherever."

He liked the sound of that. "Fine, fine," he said. Spending a couple of hours of his evening sitting at a desk while Astoria wrote lines sounded pretty dull, but it would be worth it to have Tonks in his debt. "Just one thing."

"Anything," she said, dropping her voice low and licking her lips suggestively.

"Why'd you come and ask me this now?" he asked. "Couldn't you have waited until later, when I was back in my head suite or eating breaskfast in the Great Hall or something?"

"I could have, sure," she said. "But then I wouldn't have been able to tease the four witches you shagged silly, and where's the fun in that?"

--

"This is boring."

Harry wouldn't disagree with Astoria on that point. It was just as boring for him as it was for her, and unlike her he'd done nothing to actually earn himself a detention.

"Just be happy I'm not making you use a blood quill," he said. "Or going into the Forbidden Forest, or any of the other things I've had to do during my detentions. And I'm sure you've heard Filch talk about what he'd like to do to misbehaving students. Maybe you'd be better off with him if you're this upset about writing lines."

"Maybe I would be," she said stubbornly. "At least I wouldn't be so bloody bored." She picked her quill up and threw it onto the ground.

"Pick it up," he said, rolling his eyes. Merlin, Daphne's sister was a brat!

"With pleasure," she said. She got up, walked over to where the quill had landed and bent over to pick it up. This allowed him to see that her skirt was far shorter than the Hogwarts standard, so she must have used magic to alter it. She was bent at an angle to perfectly flash him what was admittedly a very nice-looking bum covered by only a dark red thong, which offered very little covering at all.

He cleared his throat, waiting for her to straighten up and return to her desk, but she remained bent over long after the quill was in her hand. Now he realized that this was blatant on her part. She wanted to flash him her arse.

"Are you planning on returning to your desk any time soon?" he asked. He tried to sound stern, but frankly Astoria's arse was far more interesting than the transfiguration assignment he'd been trying to work on for the last hour.

"Not really, no," she said. "Why? Are you going to punish me if I don't, Potter? Maybe you'll tie me to the desk, whether I like it or not, and have your wicked way with me like a perverted professor?"

Harry raised his eyebrows. It wasn't really a surprise that Astoria was a kinky witch. He'd seen her having fun around the castle often enough to have a pretty good idea that her libido was at least a match for her older sister's. The key difference was that Daphne was at least somewhat discreet about where she did it and who might see, and he was the only wizard she'd ever allowed to touch her. He'd seen Astoria with enough partners to know that she was not as choosy, not that he really had any room to judge her for that. His list of partners was almost surely larger than hers at this point, so he wasn't about to look down on her for liking sex and exploring it with different people.

And speaking of liking sex and exploring it with different people, knowing what he knew of Astoriahe had a feeling she wouldn't mind it at all if he got up from behind his desk right now, walked over to her and shagged her rotten. He had to admit that it sounded like a much better way to pass the time than sitting there and working on his assignment while she wrote lines.

"You'd like that, wouldn't you?" he said, deciding to test the waters before he actually committed to anything or made any moves on her. "You'd probably like it if I tied you to the desk, wouldn't you?"

"Hmmm." Astoriastraightened back up and turned around to look at him. "Would I like it? I'm not sure. I know Daphne keeps coming back for more, but she's very droll and boring and not at all informative about your ability. I wonder if she keeps shagging you because you're actually good at it, or if she's only letting you get on top of her for political reasons? Tracey is more willing to talk about sex, and she's always had very nice things to say about your performance. But she's also the type of person where you can never quite tell whether they're being serious or just having you on, so I'm not sure what to think."

"And what do you think?" he challenged her.

"Like I said, I'm not sure," she said. She walked towards him slowly, and when she was standing right in front of him she shrugged her shoulders. "But I've always been curious. And even if Daphne were more upfront and I could trust that Tracey was being completely honest, I've still always been someone who preferred to decide things for myself. How can I know how good you are unless I've actually felt it for myself?"

"That's fair," he said, nodding. "Maybe if you're a really good girl and you do all your lines, we can talk about setting up a chance for you to find out why your sister keeps coming back."

"Yeah, sure," she said flatly. "Let me get right on that." She deliberately, purposefully snapped her quill in half right in front of him. She tossed the pieces onto the floor and vanished them with her wand. "Or here's a better idea. Since Tonks left you in charge of this, how about you toss those stupid lines in the rubbish and we can spend the rest of this detention doing something far more interesting?"

Harry knew that taking her up on her offer was not the mature or ‘right’ thing for him to do, and he liked to believe that if he’d been filling in for any member of the Hogwarts faculty other than Tonks he wouldn’t have gone through with it. But Tonks was different. He knew how Tonks felt and behaved, and if she found out that he’d shagged Astoria during the detention she would probably laugh, give him a high five and ask for details. If she was there she would probably even ask to join in on the fun.

“Oh, what the hell,” he said. He waved his wand at the piece of parchment on her desk, vanishing it on the spot. Then he pointed his wand at the door to lock and silence it. Even with most of the school back in their dorms and the teachers all in their staff meeting, there was no such thing as being too cautious in situations like this. “But don’t think I’m going to take it easy on you. If you want to get fucked rather than do what you’re actually supposed to be doing during this detention, I’m going to make sure you feel it.”

“Ooh, don’t make promises you can’t keep, Potter,” she said, smiling at him. “You might make me start to expect big things from you if you talk like that.”

Harry smiled, and decided to take charge immediately and set the tone. Even if he hadn’t seen some of the positions she liked to assume, the nature of her flirtations told him that she didn’t want to be made love to or anything of the sort. This was going to be very different from his first time with her older sister, which had also happened to be Daphne’s first time ever. Astoria had far more experience than her sister had back then, and she also had a taste for a much more aggressive and dominant sort of sex than Daphne would have been ready for.

He used magic to conjure cuffs that snapped into place around Astoria’s arms at the wrists, binding them together without warning. Astoria gasped at the unexpected maneuver, but when she looked up at him after taking in her new situation there was more than a hint of excitement in her eyes and on her face.

“Kinky, Potter,” she said, and the lust was even more obvious in her voice than it was on her face. “But what comes next? What will you do with me now that you’ve got my hands cuffed together like I’m the no good criminal snake and you’re the grizzled auror? Are you going to play with your prey now that you’ve caught it?”

“Get down on your knees,” he said roughly, and even to his own ears he sounded quite a bit like the no-nonsense auror that she’d described. He could have again used magic here to simply force her down, but he thought it would be more fun for both of them this way. He had a feeling Astoria agreed, judging by how he could hear her breath catch not to mention just how quickly she got down on her knees. She licked her lips and looked up at him, waiting for his next command.

He made her wait for a bit, as there were still a few things he needed to do, or rather to remove, before what came next. First he undid his trousers and shoved them down his legs, and then his boxers joined them. Out of the corner of his eye he could see Astoriawatching the reveal with great interest, and he also heard the groan of approval that came when she got her first look at him. Even before he was fully hard he still met her approval.

Her look became even more interested as he slowly walked towards her and stroked himself to full hardness. He was all the way there by the time he reached her, and her eyes were staring straight at his cock. Astoria usually appeared sarcastic and playful in his experience, but she was staring at him hungrily now.

“Mmm,” she groaned. “Well, I still don’t know if you actually know how to use that thing, but you sure as fuck have the right ingredients for the recipe if nothing else.”

“I’m so glad I meet your approval,” he deadpanned. “Now open that mouth. This is still your detention, and you’re going to need to put in some work to make up for the lines you were supposed to write.”  Astoria’s lips parted, and he shook his head and chuckled. “Not good enough. Wider.” Astoria’s mouth opened wider still, and Harry nodded.

“That’s better,” he said. “Now we can get started.” He put his hands on the sides of her head and pushed his hips forward, sliding his cock into her open mouth. Normally he would have been a lot slower and more careful in how he went about this, especially the first time he ever had a new partner’s mouth around his cock for the first time, but he felt that taking it easy on Astoria would defeat the whole purpose of what they were going for, and what she seemed to enjoy.

Everything he'd seen said that Astoria liked it rough and liked to be used hard, and so that's what he did. He didn't sit back and let her suck his cock, and he didn't give her any time to get used to having her lips around him. Harry held her by the head and fucked her face hard, driving forward so his balls smacked against her chin. Spit and drool spilled from her lips, and the harder he went, the more he was able to overcome her experience and make her gag around his cock. His was hardly the first cock she'd had between her lips, but he felt confident that he was at least as big and giving it to her at least as hard as anyone else ever had, and her gagging seemed to validate this opinion.

But that didn't change how she felt about it. He'd been sure she would appreciate having her hands cuffed and her face fucked, and he was right. Whenever she wasn't gagging around his cock she was moaning around her mouthful, and her eyes displayed her lust as she stared up at him and all but begged him to keep going.

Astoriahad found a much more interesting way to spend her detention than writing lines, and she was enjoying it. Some witches might have preferred the monotony of lines as opposed to having a thick cock stuffed so far down their throat that they kept choking on it, but Astoriacertainly was not among them. She didn't want to be at her desk; she wanted to be on her knees with her hands cuffed together while he fucked her throat.

If this was how she wanted to spend her detention, Harry was certainly happy to grant it to her. He kept thrusting his hips into her, fucking her face, pulling on her hair and making her throat his cock for the next several minutes. When she gagged around his cock he just held her down longer, and when he felt himself about to cum after a few minutes of using her mouth he decided to plow forward and go straight for the finish.

He didn't give her the option of choosing how to handle his orgasm. When he began to cum he thrust his cock down her throat and held her by the hair, giving her no choice but to gulp every last bit of his seed down. She didn't seem to mind though. She couldn't have tried to push him away even if she'd wanted to, but it sounded to him like she was actually quite happy to swallow all of his cum.

He remained inside of her mouth until he was finished, and on his way out he gave her cheek a playful slap with his cock that made her gasp and then smile up at him with delight.

"Well that was a very interesting start, Potter," she said. "But if I'm going to figure out for myself how good you really are, I'm going to need that cock inside of me for real. Assuming you can get hard again, of course." That sounded like a challenge to Harry, and challenges deserved responses.

"The question isn't whether or not I can get hard again," he said. He had no doubt about that, and in fact he was sure it wouldn't be long now. "The question is whether you're going to be able to walk back to the Slytherin dungeons on your own power after your detention ends."

--

Harry had already proven his point and shown Astoria what he was capable of beyond any room for doubt by now. He kept going not because he had anything left to show her, but simply because he was having too much fun to stop. He didn't know whether her older sister would still be up and interested in having any fun by the time he made it back to their shared suite, so he needed to make the most of his time with Astoria.

He felt like he'd used the time pretty well so far. After the facefuck he'd magicked her clothes off, picked her up, put her on top of the teacher's desk and fucked her hard from behind. She'd cum twice while he'd shagged her, but he'd held himself back so far. Even knowing he would get hard again before too long, he'd still wanted to maximize their time together as much as possible.

So he'd still been going strong when he pulled her up, undid her cuffs, flipped her over onto her back and continued to fuck her. From that position he had been better able to appreciate her body as well as how much she enjoyed having his cock inside of her. Staring at her back, seeing her sexy arse jiggle and giving it the occasional swat while he fucked her from behind had been fun, but the view of her breasts bouncing was even better in his opinion. She had an attractive pair too. They were just a bit smaller than Daphne's, but perky and very fun to play with.

Seeing her face as he fucked her was delightful as well. He'd been able to hear her moaning into the desk before, but from her back he could stare down at her wide smile as he shagged her. And that smile only grew when he fucked her to another orgasm, helped along by how frantically she rubbed at her clit now that her hands were free.  He'd entertained the idea of ordering her to stop and asserting more control over the detention, but had decided to let her play with herself instead. Seeing her desperation and horniness was both entertaining and sexually exciting for him, so he'd let her rub to her heart's content while he fucked her on top of the desk.

Then he’d picked her up in his arms, held her by her arse and bounced her on his cock for a bit. She’d screamed her way through at least two orgasms while he was doing that. It was entirely possible she’d had more, but at some point she’d screamed herself hoarse and it became harder to tell.

Now he had his arms hooked underneath her thighs, holding her up and supporting her weight while he fucked her. Astoria’s own arm was thrown over his neck and she gasped quietly near his ear as she took her pounding. She was exhausted, but at no point throughout this entire ordeal had she ever asked him to stop, nor had she ever looked upset or even weary when he moved her into a new position. Her body might be tired and her energy might be drained, but Daphne’s little sister was still enjoying herself very much.

“How do you like it, Astoria?” he asked. “Still think that your sister might only keep shagging me for political gain, or that Tracey was just having you on?”

Astoria’s head lolled in what may have been a shake, and she groaned something that sounded vaguely like a no. But again, Harry didn’t really need any confirmation from her. He knew what he’d achieved; this was all just for pleasure and entertainment at this point.

He fucked her for a few more minutes, choosing not to taunt her anymore and instead simply enjoying the feeling of fucking the younger of the Greengrass sisters. The shag he’d given her was sure to stick with her and influence how she looked at all future lovers, and while he was proud of that, he was currently more focused on the present than on either of their futures.

He’d been holding back for quite awhile now, wanting to fuck Astoria for as long as possible before finally giving in, but he felt the call to release growing stronger now. He speared into Astoriaa few more times and then held his cock deep inside of her while he came. She let out a sound that sounded suspiciously like cooing, so he could only assume that she approved of his decision not to pull out and fill her up with his seed.

Astoriastumbled when he put her back on her feet, and Harry caught her by the arm to make sure she didn’t fall flat on her face.

“Alright there, Astoria?” he asked. He nearly burst out in laughter as she turned her head to make eye contact with him and he saw how dazed and confused she looked. He knew he’d fucked her hard and for a long time, but with her experience he didn’t expect her to look that out of it!

Her eyes cleared somewhat after a few seconds, and she blinked and stared at him before looking down at her pocket watch. Her eyes widened and she shook her head slowly.

“Bloody hell,” she whispered, voice scratchy and hoarse.

“What is it?” he asked curiously.

“Look at your watch,” she said. Harry did so, and his own eyes widened when he saw what she’d seen. Had he really been fucking her for that long?!

“Well, since your detention technically ended three hours ago, I guess as your Head Boy it’s up to me to make sure you don’t get in any trouble,” he said. “I’ll help you clean up and walk you back to the dungeons.”
