A/N: The idea for where the 'adult interaction' occurs in this chapter came from Padfoodsgrl79. This one's for you.

Sorry for the delay. I've had a bit of writer's block when it came to this story. Ugh. Enjoy and please review.

The next Friday night Hermione and Ginny got permission to Floo back to Grimmauld Place so they could go to Ron's party. Harry and Sirius were waiting for them in the kitchen with dinner already on the table. Kreacher appeared to take their overnight bags upstairs, and the girls sat down to eat.

"How's Auror training?" Hermione asked Harry as he passed her a basket of rolls.

"It's so cool," Harry smiled excitedly. "Right now we're learning rules, there's about ten million of them, but there's lots of practice scenarios. Next week we're going to be taught when we can use the Unforgivables, and after that they're going to teach us how."

"I'm not sure I want to know about that," Ginny scowled. "I don't like the idea of you being in a situation where you might have to use one of them."

"It's part of the job," Sirius pointed out. "Sometimes it's in everyones best interest to finish someone off."

"But why would you need to know the Cruciatus or the Imperius?" she sounded like she was getting worked up.

"The Imperius helped us get into Gringotts. It has its uses," Hermione pointed out.

"And the Cruciatus, well, sometimes you need to get information very quickly..." Sirius started.

"Why do they even bother calling them the Unforgivables, then?" Ginny nearly shouted. "Why don't they call them the Forgivables If You're A Bloody Auror?"

"It's against the Muggles' laws to kill," he said, looking to Hermione to see if she was motioning for him to just drop it, but she wasn't saying anything. "But armies do it all the time. Police officers do it if needed. Hell, in the States nearly every bloody police officer carries a gun. It's to protect themselves and the innocent people. If, as an Auror, Harry has to lob the Avada at some Death Eater out to kill whoever he can get his hands on he better well know those Unforgivables."

"So you're saying it's okay to kill someone if you think they might kill someone if you don't?" she argued.

"If you have a very good reason to believe they will, then yes. I'd much rather a Death Eater snuff it than some poor kid. Though if I was on the squad I'd much rather hit them with a Crucio to bring them down, then hand their ass over to the Dementors with a free ticket to do whatever they want."

"You're horrible, Sirius Black!" she cried. "You would torture someone, then hand them over to get their soul sucked out of their bodies?"

"If they deserved it," he shrugged. "I can think of several who are more than worthy of that particular treatment."

"Don't even get him worked up," Hermione warned as Ginny opened her mouth again. "I talked to him about this last week. He's pro-death penalty and pro-Azkaban."

"For those people who deserve it," he clarified. "I'm not saying lets have a free-for-all chucking into prison. I don't think you should be able to accuse your neighbor of illegally trading dragon eggs and get him locked up in Azkaban if all he really did was kept you up with loud music one night."

"But you think there are crimes worthy of putting people to death for? You believe in eye for an eye?" Ginny looked livid.

"It doesn't work in all cases," Sirius said coolly. "Barty Crouch Jr. tortured Neville's parents into insanity. But he's already insane, so we couldn't return the favor. Does he deserve to be blasted off the face of the earth for what he did? Hell, yes, he does. Though he got the Kiss, I guess that will do."

He had known exactly which name to pull out to stop the conversation. Ginny still had a sore spot over what happened at the final task of the Triwizard Tournament, and mentioning the fake Moody put Sirius' argument into perspective with her.

"How's Hogwarts?" Harry asked, quickly trying to change the conversation and move on.

"It's good," Hermione nodded enthusiastically. "NEWTs are coming up, so we're all studying very hard and working on our papers and such."

"NEWTs are months off!" Sirius groaned in disgust. "What in the world are you studying now for?"

"Some people like to be prepared," she shot back.

"Are we going to be able to have any conversation that doesn't involve us arguing over something?" Harry sighed exasperatedly.

"But this is so much fun, mate," Sirius beamed. "And besides, you want to get 'em riled up. Makes the sex better."

"Sirius!" Hermione blushed furiously.

But he had opened the door and said the 'magic' word. He and Harry now had a singular goal- to finish dinner as quickly as possible and get Ginny and Hermione upstairs as quickly as possible.

Ginny and Hermione had caught on, and had both started eating very slowly, talking about banalities like the weather, trends in fashion, and the latest edition of Witch Weekly. Harry and Sirius had finished before the girls were halfway done, and they were both looking antsy as the girls struck up another conversation about how Hermione was thinking of styling herself.

"Maybe we should just go catch a Quidditch match," Sirius growled in frustration.

"Maybe," Hermione said, waving her hand dismissively. Ginny snickered.

Harry rolled his eyes at his godfather, then started clearing the mess from dinner.

"Oh, damn," Ginny muttered.

"Stay strong," Hermione encouraged playfully.

"What?" Sirius said, looking confused.

"He's doing housework," Ginny giggled. "Nothing puts a woman in the mood quite like a man doing housework."

Sirius jumped up to help Harry.

"It doesn't count once you're let into the secret," Hermione smirked as he took her plate.

"I guess I'll just have to be charming in other ways," he said, giving her a wink. She sucked in a deep breath as she tried to control the wave of desire that had swept over her.

"You know I'm a lost cause," Ginny whispered as the men started washing the dishes by hand, making a big deal over it. "I haven't seen Harry since before school started."

"We're both lost causes," Hermione whispered back with a grin as she watched Sirius mutter something to Harry. "But if we can hold out a little longer they'll have this kitchen sparkling."

Ginny laughed. "Think I should tell Harry there's no bigger turn-on than a shiny, clean bathroom?"

"You've spent way too much time around Fred and George," Hermione shot back.

"A girl needs her role models."

It took Sirius and Harry ten minutes to do the dishes without magic, and another five to get the rest of the kitchen clean with. Once they were done Hermione and Ginny pretended to inspect the place as if their whole night was going to be determined by whether or not they found a spare breadcrumb lying around.

"What do you think, 'Mione?" Ginny asked as they finished their inspection.

"I guess it passes," she said, shrugging her shoulders casually.

Unable to wait any longer Ginny grabbed Harry's hand and pulled him quickly from the room. As soon as they were gone Sirius strode up to Hermione.

"Shall we?" he asked, kissing her hand lightly.

"We shall," she replied with a giggle, and she let herself be led from the room. "By the way, what did you tell Harry earlier?"

"That once he goes upstairs he should stay up there for a while," Sirius said as they climbed the staircase to the entrance hall.

"Why?" she whispered as they neared his mother's portrait.

"Because I need down here to be private for this," he said, suddenly turning and pinning her against the worn green curtains of his mother's portrait.

"What are you doing?" she hissed in fear and excitement as his lips started tracing her neck.

"You suggested doing it against the Family Tree. I'm just doing one better," he replied between kisses.

"She's going to wake up," Hermione groaned, starting to not care where they did it as long as he took her soon.

"She can't get the curtains open with your back there. She can holler all she wants, and she'll have a good idea of what's going on, but she won't be able to see us," he said, pressing her firmly against the wall.

She gave in as his lips found the spot behind her ear. Her legs threatened to give way, but even if they had his body weight pressed against hers would have kept her in the upright position. She wrapped her arms around him and pressed herself to him as much as she could with his body holding hers against the wall. She heard something rustle behind the curtain, but she didn't care.

One hand of his steadied himself on the wall, the other hand reached down and lifted her skirt. His fingers ran over her panties.

"It doesn't take you much to get all worked up, does it, minx?" he growled into her ear.

"Shut up, Sirius!" she groaned, pressing herself into his hand.

"Yes, ma'am," he chuckled, hand cupping her bum and pulling her body to his. She was lifted onto her tip toes and she had to grab the curtain to keep from falling. He chuckled again and pulled her panties from her, tossing them to one side and returning his hand to her with one fluid motion. His calloused fingers slid over her wet folds, and she stumbled slightly trying to press herself into the touch.

"Trust me," he hissed at her.

"I do," she said, hands fumbling at his tight black jeans. Just as she had pushed them away from his erection he reached behind her, lifted her up by her bum, and wrapped her legs around him. She gasped at the sudden movement, then it turned quickly into an moan as he slid himself into her.

There was definitely some muffled words coming from behind the curtain, but her brain was focused only one Sirius. She gasped with his each of his rapid thrusts, her hands wrapped in the curtain. He opened her blouse and growled.

"No bra today?" his thrusts paused for a moment.

"Thought it might get in the way," she said, grinding her hips urgently against his, begging for him to continue.

He chuckled again as his lips found hers. The hand not supporting himself found her breast, and she moaned into his mouth.

"Traitor scum!" Mrs. Black's voice finally managed to make it through a small crack in the curtains.

"Should I curse her?" Hermione asked in a whisper.

"Moan louder for me, baby," he said, hand tweaking a nipple. "Drown her out."

She obliged as he bit gently on her neck and rolled her nipple between his fingers. He started pounding into her with more ferocity and she couldn't quiet herself. Her legs squeezed around his waist as she began to feel herself nearing climax.

"Come for me, Hermione," he growled as his hand snaked around her back to hold her to him. She could feel his legs shaking slightly with the effort of holding her up and holding back his own climax. She shifted her hips slightly, and that did the trick. Waves of pleasure rushed over her, and she groaned his name loudly one last time. His hand on the curtain had tightened with his own climax, and the other hand left her to help steady himself. His body weight was the only thing holding her up as he leaned against the wall and waited for his breathing to return to normal.

"What a good little kitten you are," he whispered into her hair as he backed off her enough to let her slide her legs down his and steady herself on the floor. Her arms stayed over her head, wrapped tightly in Mrs. Black's curtains, which were fighting to fly open as a muffled string of obscenities flew from behind them.

"Mind helping me get my clothes back on before I let your mum loose?" she asked coyly.

"I rather like you like that, love," he smirked, but he stepped forward to button her blouse back up, taking his time with each button. He lowered her skirt and made sure she was covered, but pocketed the panties he had pulled from her.

"Whenever you're ready," he said, bracing himself for the onslaught.

Walburgia Black's words came quickly and viciously the moment Hermione's hands left the curtains. They flew open with enough force that she stumbled forward a couple steps. He caught her, and they stood, watching his mother scream herself hoarse for five minutes before she needed a rest.

"You know, you could have summed that up nicely with, 'Son, I'm not happy you're seeing a Muggle-born, and I'm very unhappy at your choice of locations for your adult activities'," Sirius said dryly as she took a few deep breaths to get her second wind. "That's what a good mother would have done. Though you weren't worried about being a good mother, at least not when we were locked up in here, were you?"

"You are no son of mine, you blood traitor, you filth, fouling up the house of my ancestors with that Mudblood filth!" she managed to shout.

"Let's go, Sirius. I don't like spending time in around idiots," Hermione muttered, tugging at his hand.

"No. Let's stay. You know, mum, I was thinking of giving her one of the Black family heirloom necklaces. I think the silver and emerald one would look good her eyes, don't you? She has such a pretty little neck," he said smugly, lifting her hair away from her neck and running his fingers delicately over her skin. "But I'm not sure if I should. I wouldn't want to soil it with something that's been around on your scummy skin."

This set off another round of shouting. He wrenched the curtains shut again, then led Hermione towards the stairs.

"That was some display for your mother," she said as she followed him towards his bedroom.

"I wanted to hammer home the fact that you're much more than something I'm using for physical pleasure. Most of the Black men have had Muggle-born girlfriends on the side, that part's nothing new. Mudbloods for fun, purebloods for keeps."

"That's disgusting," she muttered.

"That's old wizarding families," he pointed out.

"So, do you get off on antagonizing people?" she shook her head.

"Merlin, no. She's my mother. It's been a while since I caused mischief on a grand scale, I thought it might be time."

"You forgot you terrified a bunch of first years by making them think there was a Grim sitting outside the castle," she pointed out.

"Unintentional, love," he said. "I have to do this properly," he added as they reached his room, lifting her into his arms and carrying her over the threshold.

"How chivalrous," she giggled as he deposited her on the bed.

"I think that was somewhere in the Gryffindor job description," he chuckled as he crawled into bed beside her. "I have to make sure I'm living up to my reputation as a disgrace of the family."
