A/N: Because I have some very Remus/Hermione centric posts coming up I decided to give Sirius and Hermione some more play time. Hope you like it Team Sirius! And everyone else too! BTW thanks for your awesome reviews!

Sirius and Hermione woke at about the same time, both shifting around under the blanket in discomfort for different reasons. Sirius simply wasn't used to sleeping on anything other than his ridiculously plush bed and Hermione was startled by her massive headache. It was the worst hangover she had ever had.

"Mmm…good morning, love," Sirius stretched his arms out and groaned, trying to wake up. Hermione grimaced in pain as the light was starting to hit her eyes and she clutched to Sirius' chest, burying her head there, not wanting to move an inch.

"I feel like I am going to die," she whispered. Sirius laughed and even that small noise hurt her head.

"I'll be right back," he chuckled, getting up and she just curled up in a ball under the blanket in his absence. Sirius found his boxer briefs and slipped them on before walking out of the library and into the kitchen.

Remus was at the countertop, reading the Prophet, drinking tea, and eating some oatmeal with fruit. It never ceased to amaze Sirius that his best mate could be so decidedly domestic and boring sometimes. Sirius began rifling around in the cupboards looking for a hangover potion.

"Good morning. How was last night?" Remus asked with definite amusement in his voice, although he didn't look up from the paper.

"I had a nice time, but Hermione is in pain…" Sirius laughed, "Where are the bloody potions, Merlin Remus you know we have an issue with this…"

The werewolf laughed and Sirius turned to his friend, who was twirling the last bottle of the potion in his fingers, "I knew you'd come looking for it. I heard her stumble in in the middle of the night. Among other things."

Sirius took it gratefully, sauntering back into the library. He pulled the covers off of Hermione who squirmed and pleaded for them back, which just made him laugh harder. He handed her the little vial of potion and she swallowed it quickly. She was always amazed at how effective that particular potion was. Her headache was all but gone and she no longer felt like complete shit.

Sirius, noticing the instant change in her, got back down on the ground and cuddled up next to her, taking her in his arms. It wasn't something he ever thought he would willingly do, but he found he was surprising himself constantly.

"So, are you going to tell me what happened last night and why you so badly needed me to fuck you like that?" Sirius asked into her ear. The words weren't sensual and they sounded harsh coming out of his mouth, like he was uncomfortable saying it.

She wriggled in his arms, turning to face him. Her hangover was all but gone so she couldn't feign anything and avoid the question. But if she was being honest with herself, she had wanted to tell him all week.

With a heavy sigh, Hermione said, "Earlier this week, the night after you came and visited actually—Remus told me he loved me. But when we made love he was different. He almost didn't want to. And he said he was scared he'd be rough with me. I told him I wanted all of him, but he seemed so strange. And we've been a little off since."

"So that explains why you were practically dying for it. You wanted it from him, but you knew I'd give it to you," Sirius said slowly and sadly. He felt like a knife was being twisted in his heart and he reminded himself that it was this very reason why he had decided to never love again 27 years ago.

"No, oh no Sirius that's not what…"

"Yes it is. We both know it is." He said it sharply, trying to mask his hurt. He closed his eyes for a moment; he didn't want to look at the beautiful goddess that was nearly breaking his heart.

"Sirius Black, stop it!" she rolled on top of him, pinning him to the floor so he would look at her, "I love you. And I mean that. I knew you would give me what I needed because you can open yourself up to me. You showed me this week that you can be a gentle, loving man—but also that you can really fulfill my deepest desires. I need both. And even though it might have stemmed from my annoyance with Remus, I am very very happy for what happened between us."

He looked at her for a moment, and he understood. It was just his natural instinct to not want to share, and he never had to before this. He also wasn't used to being the more giving one out of the two men. Remus usually won the role of romantic knight in shining armor and Sirius was perplexed at why the man was being so distant.

He had noticed it the afternoon before when they had returned together. He seemed drawn, and less happy that usual.

"I'm glad, Hermione," he smiled and kissed her and she rolled off of him and snuggled into the space where his arm met his chest. She fit there perfectly and Sirius thought it was all so damn cute that he could barely stomach it. But suddenly his thoughts drifted to something she had said.

"Remus said he was afraid he'd be rough with you?"

"Yeah, he said something about marking me. And I said I didn't mind if I had…"she stopped before the jealous look on Sirius' face grew any further. He calmed himself with a deep breath.

"He wants to mark you…" Sirius sighed.

Hermione touched the love bites trailing all the way down her neck and breasts, "And as you can tell…that isn't a problem," she flirted. He loved her teasing, even if she was taunting him with being given hickeys by another man.

"No, Hermione he wants to mark you as his mate," Sirius' voice was very authoritative. And he seemed clearly upset, "This isn't good…"

"What do you mean?"

"For a girl who's read every book in the Hogwarts library twice, I would have thought you would be aware of this…" Sirius said gruffly.

"Well I am not, so explain it to me. I've read my fair share of werewolf lore, and I don't know what this marking business is!" she raised her voice to the challenge of his. She hated when he put her in her place like that, and yet loved it at the same time.

"If a werewolf has the inclination to bite someone, it means he sees the other as his soul mate. The other might not necessarily feel the same; but for the wolf, the urge is very strong. Once a werewolf bites and marks…usually during the act of lovemaking, it doesn't change the other into a werewolf. It simply attaches them to the werewolf for life—a bond stronger than marriage. There can't exactly be a divorce, you see…" he explained, all the while Hermione was drinking in the information; curious and scared at the same time.

"So he's scared to really make love to me because he might lose control and mark me?"

"Precisely," Sirius told her, "And I for one, don't know how I feel about that. It's a scary thing to go toe to toe with a werewolf who wants to mark someone. But for you, I will."

"How do you know so much about this?" Hermione asked suddenly and Sirius' eyes darkened.

"It's happened before. Remus thought Dora was the one. He felt it for her too. And when he explained she ran…into the arms of…"

"Stop," Hermione told him and he did. She was panicked. She loved Remus. Truly, madly, and deeply. But she felt the same for Sirius. She didn't know how in the world it was possible, but they literally possessed two separate halves of her heart. As much as the thought of Remus marking her thrilled her, it also meant no more Sirius. And besides, that was a huge decision. She could understand why he had been distant.

"I need to talk to him about it," Sirius said.

"No…"

"Yes, because I know you aren't ready to start making any kinds of decisions. And because I care about him, and I don't want him to lose you. I'd rather help him if I can."

"You are a good man, Sirius, better than you think you are," she whispered to him, giving him a kiss before he got out from under the covers and stood up. He gave her a sweet smile as his brain filled with more than a few terrible outcomes to their current situation. He wished this could all be easier. But it was love, and that was never easy.

He settled instead for something he knew implicitly. Something, that especially with her, never disappointed him.

"I'm going to take a shower, care to join me?" he offered out his hand and she could easily see he was trying to ignore their current predicament for the time being, which she was quite okay with. She smiled and he pulled her naked body out from under the covers. They walked through the back door of the library which led directly out to the bedroom hallway instead of to the kitchen like the other door did. This way they were able to sneak into his room unnoticed, except for their laughing.

The bathroom attached to Sirius' bedroom was done up just as sumptuously. The towels were red and black with his initials monogrammed in gold thread on all of them. He pulled her into the rather large black tiled shower and it instantly enveloped them in a wonderful stream of perfectly heated water. They kissed under it and he pulled her closer to him, enjoying the new sensation of their bodies together under the water. Hermione had never had shower sex before, but she was more than pleased that she was kissing a sopping wet Sirius who, in no time at all, became raging hard for her once again. The man was insatiable.

And if she was being honest with herself, she was starting to become insatiable too.

He pressed her up against the tile which was cold in comparison to the water and kissed her softly, his fingers working into her wet hair and tracing trails of water that were snaking in between her breasts. He was right at her entrance, teasing her there and she reached down to stroke his long length in her hand as he nipped at her ear, tugging the lobe with his teeth before pushing her hand out of the way and sliding inside of her.

It was much slower than the night before. Although she was quite sore from that experience, this new feeling was intimate; with the water around them, beading on their eyelashes as they kissed, and his strong arms bracing her against the shower wall which was in all actuality big enough to be a walk in closet; and she loved it.

Sirius Black was making love to her. Maybe it wasn't in a bed, but it was damn good.

His hips moved deliciously slow, filling her as she rocked against him. It was one of the most sensual experienced of her life, and it was the first time she heard him moan. He had cussed during sex before, and called out her name, but he had never moaned like this. It was an addicting sound, and it turned Hermione on even more to know she had caused it to come out of his mouth.

She rolled her hips, allowing him to go deeper, but they were both in no rush. She felt her orgasm slowly building; but she knew she wanted this as long as she could stand it. The way he was touching her was soft and so different from the night before. Two sides of the same mad; both sides she loved.

He grunted and then groaned even louder as he slowly worked in and out of her, the sound of the water drowning out everything but their noises for each other and her fingers dug into his shoulders ever so slightly as she reached a new level of pleasure.

It was the longest they had ever gone. She had no idea how long they were in there, judging only from the wrinkles on the pads of her fingers and the steam filling the bathroom; she guessed an hour. But they didn't stop. They didn't want to. Anytime either of them came close he paused and kissed her till they were out of breath and they continued again. It was like they never wanted to leave each other's arms and it was like nothing else mattered but the two of them there in that moment.

Hermione felt so wanton and tortured by him, in the best way possible, and at last she felt herself clench around him. His breath quickened and this time he moaned her name…long, drawn-out, and slow as he came inside of her. She succumbed to it seconds later; her world quaking around her in an amazing orgasm.

The little black owl was pecking on the window of the sun room. It was thoroughly annoying Lupin who was trying his best to ignore the tantric moans coming from Sirius' bedroom and finish the paper. But when the owl didn't leave, he was forced to open the sun room windows to the balcony, which was the only place they could really receive owl correspondence. He gave the little bugger a bit of a biscuit and took the attached letter, ripping it open as he walked back inside.

When he saw the handwriting, he blanched and almost dropped it. And then he almost ripped it up into a thousand little pieces. But something inside of him willed him to read it. He didn't know if it was his anxiety about Hermione, or the jealousy that was hard to contain as he had listening to them having sex twice in the past eight hours—but he read it.

-Dear Remus,

Ron and I have broken up. I realized that I left to most special man in the world for someone that wasn't quite as much of a challenge, but in the end he just wasn't you. I know I said some awful things, but I really hope you can forgive me and we can put all of this past us. I made the worst mistake of my life and I promise you that I will spend the rest of my life making it up to you. Let's please get together and talk about this?

- Love you for always, Dora.

A/N: UH OH! Tonks is back! So please leave me a review. I have been super sad that I haven't been getting as many…and I can withhold posts…I'm just kidding I would never be so cruel…but seriously haha.
