Summary: It was a love story doomed from the start. The dark Lord wants her and Sirius must give her to him, to keep her alive. That's why she thought he didn't love her, and that's why Bellatrix Lestrange is the way she is and why she has done everything she has done. Because nothing is ever As It Seems.

(Au story, in this universe Bellatrix is the same age as Sirius)

As it Seems

He could see the tears glistening in her eyes as he sat next to her. He glanced around to see other mourners sitting there row after row, some weeping some sat their in shock. They were in the great hall of Hogwarts and as the school mourned the loss of a pupil, Bellatrix mourned the loss of her boyfriend, Martin Littlewood. Sirius noticed she didn't shed a tear and he knew she wouldn't even though her eyes sparkled more than normal. She was in pain, but she never showed it. Never.

She and Martin had been dating for a couple of months, but deep down she was glad he was gone. Sirius knew that. And Sirius was very glad he was gone. He hated him for a number of reasons but still felt guilty for the fact that he had murdered him. He wouldn't have been sat in that hall if it wasn't to support Bellatrix. Discreetly, he took her hand and squeezed it. A smile twisted on her lips.

After a few more minutes the hall began emptying out. Sirius leant forward and whispered in her ear. "See you soon, Belle"

He stood up and walked out of the hall. He ran upstairs to Gryffindor common room and then up the stairs to his bed. He sat on it heavily with his face in his hands. He was a murderer. There was no denying it. He knew and Bellatrix knew, but the rest of the world thought it was an accident. A tragic accident. But the world saw nothing. It didn't see the bruises Martin gave Bellatrix or the scars she had on her back. He was 17 years old in love with his cousin and a murderer. He couldn't tell James or Remus, they wouldn't understand. How could he tell them he loved his cousin? Never mind the fact he murdered Martin? He didn't mean to kill him, he just couldn't control his temper.

Sirius tried so hard to not be like his family. He didn't share their opinions, didn't want to marry pure bloods and only pure bloods. It was no secret the Blacks had a history of incest to carry on their pure blood status. And that was why it was so ironic. The fact that he tried so hard to be anything but his own family, he just didn't realize. He didn't think he was anything like his family, after all they had disowned him already. That's why their affair had to be a secret. He didn't want Bella to be disowned for being with him. He didn't want her to be outcast to her entire family, tormented, tortured like he had. On top of that he didn't work this hard at being disowned to be anything like his own family. He didn't want to be seen as a hypocrite after all.

"Sirius" His thoughts were interrupted by a familiar hiss of his name. It was coming form under his pillow. He pulled out the familiar gold edged mirror and smiled at a very familiar face.

"Hey" he whispered back.

"Meet me?" she asked

"2 Minutes, ok?"

She smiled seductively.

"See you there" she hissed. And with that she was gone.

Sirius put the mirror back under his pillow and moved to stand by the bed next to him. He opened the cupboard which belonged to his friend and took out a cloak. He threw it over him and walked out of the room.

She sat their on a chair in the room of requirement. Their secret place. The room was filled with junk, old folders, black boards, cupboards chairs etc. She turned around sharply.

"Sirius?" she whispered.

There was no response.

She pulled out her wand and aimed it at the door.

"Boo" she turned around fast to see Sirius standing behind her almost touching her.

"What took you so long?" she asked.

He responded by kissing her fiercely, exploring her back with his hands. She ripped off his shirt to reveal his tight, muscular stomach and wrapped her legs around his waist. He unfastened her top to reveal her lacy black bra. She could feel his hand move higher up her thigh, up her skirt and she moaned quietly in anticipation. She began kissing his neck as he stroked the edge of her panties.

"Don't tease me" she panted pulling his lips onto hers.

He began pulling her panties down until she whispered "Rip them" in his ear. He ripped them gently. She wrapped her legs tighter around his waist as he quickly undid his jeans. She could now feel his erection rubbing against her. She knew he was doing it on purpose, teasing her.

"Enter me" she whispered and with that he pushed into her with her back against the wall. She panted a little as he pushed into her again reaching further inside her. He repeatedly pushed into her not wanting to go too hard and hurt her. "Harder" she'd encourage and so he would. By now he used his hand to rub her clit which he could tell she was enjoying. He quickened his pace until a wave of ecstasy filled her making her moan harder. He knew his cock was covered in her juices as he continued to pump in her. "Come for me" she whispered and as she did he moaned and so did she. They collapsed on the floor together and he put an arm protectively around her.

"I'm sorry about Martin" he whispered uncomfortably. Knowing this was completely the wrong place and time to say it.

"Don't be, I'm not" she reached up to him and kissed his lips.

"Thank you Sirius, for saving me from him"

"I'll always protect you, Belle"

"Sirius?"

"Yeah"

"I love you, you know that?"

"Yes, and I love you too. But we can never say that to eachother again."

"Why?" she asked

"Because we can never be together properly."

"Why can't we say it?"

"If we say it, it makes it too hard. Always know I love you Belle, no matter what, and I'll do anything to keep you safe, but never tell me you love me again okay?"

"Okay" she smiled

And kissed him once more.

"We better go, they'll be wondering where we are"

They stood up, got dressed, kissed goodbye and went their separate ways.

He stormed down the corridor. "No way Bellatrix" he yelled.

"Shut your dirty Fucking mouth Sirius" Bella replied

"Ohh, temper temper! Looks like the family is influencing your mind" he yelled at her.

She turned and pointed her wand at him, scowling at him with her evil smile.

"Can't you come up with your own come backs" he teased once again.

A crowd surrounded around them. "What's going on?" a younger brown haired kid asked. "Sirius and Bellatrix arguing again" one replied in a bored tone. "Why are they fighting?" the first kid asked again. "Everybody knows they hate each other, do they really need a reason?" the second snapped back.

"Aaargh" Bella screamed sending a spell at Sirius in which he repelled. "You bitch" he screamed back almost as loud, firing a different spell at her. She ducked and it hit a first year in the face. Immediately the kid went rigid and fell to the ground.

Bellatrix flashed Sirius an evil glare and a cackle before she stormed off. "You're in trouble now" she yelled back.

Sirius stood their for a second as the crowd tried to help the kid up. "Sorry" Sirius muttered and he walked away quickly. He walked to the first floor bathroom where he entered through the door. As he closed the door behind him he felt himself being pulled around the corner.

"Was there any need to duck?" he asked jokingly.

"Shut up and kiss me" she replied. He kissed her, his lips begging hers to part so he could deepen the kiss. They did and he did as he entered his tongue and massaged hers with it.

It had been going on for two years now. Neither could deny the other. The first time it had happened they put it down to temporary insanity. But they couldn't resist each other. And so at any chance they had they met up. And it soon became more than sex or physical attraction, they began to feel a lot more for each other. The outside world, their friends none of them knew and they had to argue in public, they had to make it look like they hated each other. To keep her in the family and to keep it a secret. They had both agreed as soon as anyone found out it must end, because if it didn't it would never work. It would cause too much trouble for everyone. No-one must ever know. That was their only rule. But rules are made to be broken and that's exactly what happened the following day.
