Bellatrix woke up slowly and felt around for Narcissa. She couldn't feel her. She sat up and rubbed her eyes. As she gained her sight back, she looked around. She was alone. Again. 'Hmm…' she muttered to herself. She lay back again, wondering where her sister could have got to.

She shut her eyes and imagined feeling her sister. Touching her. Smelling her. Narcissa made all Bellatrix's senses become heightened. Taste was the best of all. The way Narcissa tasted was sweet. Such a beautiful taste. Bellatrix was getting wet just from the thought and just as she was reaching down to have a little time to herself, Narcissa appeared suddenly. This made Bellatrix jump.

'Didn't think I would miss out on this did you?' Narcissa joked.

'Cissy! Where did you go?'

'That's not important right now. What is important is sorting you out.' She winked as a naughty smile appeared on her lips.

Narcissa reached under the sheets, knowing that Bellatrix still wouldn't be dressed, and found her warm dripping core with her hand. Bellatrix jumped again slightly as her sister's fingers touched her clit. 'God…' she moaned. Narcissa smiled again and pulled the sheet off her sister and moved herself between Bellatrix's legs. She put one hand on each of her sister knees and pushed her legs down to the bed, exposing Bellatrix completely. Bellatrix moaned again as the cold air met her hot core. Narcissa, who was now kneeling in front of Bellatrix, bent over, her mouth meeting Bellatrix's clit. She moved her tongue over it, making Bellatrix moan even more. Narcissa couldn't resist any more and moved to Bellatrix's opening. She teased her for a few seconds before pushing her tongue deep into her sister. Bellatrix cried out in pleasure. Narcissa moved her tongue in and out several times before leaning back and pulling off her own clothes. She climbed up Bellatrix's body, like a lioness hunting her prey, her lips finding her sisters. Narcissa didn't even request entrance before she pushed her tongue into Bellatrix's mouth. Bellatrix moaned into the kiss. Narcissa's thigh was in-between Bellatrix's and she could feel the heat against her cool skin. She pushed her thigh on to her sister's pussy quite hard, causing Bellatrix to throw her head back, breaking the kiss.

Narcissa parted her legs more spreading them over her sister, straddling her lower stomach. She knew that Bellatrix would like the feel of her against her skin. She thrusted her hips forward brushing her wet opening against her sisters. They both moaned, looking into each other's eyes. Narcissa knew that Bellatrix wanted more, so she grinded her hips even more against her sister. Bellatrix loved the feeling of Narcissa's wetness against hers so she took control, pushing her sister off her and on the bed. Bellatrix moved down Narcissa, kissing her body as she moved. Narcissa knew what she wanted, so she repositioned herself as Bellatrix did the same. Their
legs interlocked as they moved closer together, their dripping pussies met. They both moved their hips together, first slow, but then faster and harder.

Their hips moved at the same pace now, their sensitive clits rubbed together. They could both feel their climax approaching. When they were together, neither of them could last very long. Just seeing each other got them wet and the lightest touch could cause them to go over the edge. As their orgasms got closer and closer, they both started to moan louder and as they moved against each other once more, they both exploded into a moment of mind blowing pleasure. They both screamed out at the same time, calling each other's names. Their bodies collapsed against the bed and they panted hard, trying to get their breath back.

After a moment of recovering, Bellatrix moved back up to Narcissa. She watched her chest as it moved slowly up and down with every breath she took. Bellatrix's eyes traced every inch of Narcissa's body. Her hair was messy and she was hot and still panting. Bellatrix couldn't help but smile.

'What are you smiling at?' Narcissa asked smiling back at her.

'You are so beautiful Cissy.'

'Have you seen yourself? Stunning.'

'I am nothing compared to you…' she looked down at her hands with embarrassment. Narcissa pushed herself up so that she was sitting facing her sister. She lifted her chin with one finger so that Bellatrix's eyes met hers. She looked into her dark eyes for a second and then kissed her. The kiss was so passionate that Bellatrix forgot where she was for a second. She just forgot everything.

Bellatrix and Narcissa spent the whole day together. They talked about everything, cuddled and kissed but Bellatrix knew something was worrying her sister; there was something not quite right about her. She was different. She decided to try and forget about it, and focus on having a good day with Narcissa. She knew that if this continued she would have to ask what was troubling her. But for now, she put itaside and thought she would find a better time to bring it up.

The sun was setting over Lestrange Manor. Birds were singing happily and there were butterflies fluttering though the midevening air. Bellatrix and Narcissa had decided to make the most of this beautiful evening and were sat outside. Bellatrix was laying with her head in Narcissa's lap, and Narcissa was playing with her hair as they sat in silence. Nothing needed to be said. Bellatrix was happy just laying

there with her beautiful sister.

Narcissa broke the silence. 'You know this morning, you asked where I went?'

'Mmhm.'

'I went home, to Malfoy Manor. Lucius wanted to talk to me.'

'Oh? About what?'

'Bella, he knows about us.'

Bellatrix sat up. She was confused. How could he know? There was no way he could have found out. The only people who knew were herself and Narcissa. Thoughts raced though Bellatrix's mind.

'I don't know how he knows Bella. But that isn't the important part.' She hesitated slightly before continuing. 'He doesn't want me to see you anymore. He wants me to leave you.'

'No. I won't let him take you away from me.' Bellatrix's eyes began to fill with tears.

Narcissa reached for her sister, but Bellatrix moved away. 'What did you say?'

Narcissa was silent.

'Narcissa. What did you say?' Bellatrix's tone was becoming harsher. She knew her sister was weak, especially when it came to her husband.

Tears fell from Narcissa's eyes now, as she looked away from her sister. She couldn't bare to see the pain in her eyes. 'I told him I would do as she asked. Tonight will be our last night together.'

Bellatrix took a deep breath, trying to calm herself down. She knew that her sister still wanted to be with her but Lucius was a powerful man. He was one for getting what he wanted.

'I would have said no, but he hurt me. He wouldn't stop. I begged him to stop, I did. But he wouldn't.' The tears started falling harder now from Narcissa's brown eyes.

'Cissy you can't go back to him. Stay here, I will protect you.'

'No. If he knows I am here, he will hurt you too. I couldn't live with
myself knowing that I was the cause of your pain.'

'I will get you out of this. Even if it means we leave here. I can't have you going back to him.' She moved over to her sister and pulled her close to her body. They sat in the grass for a moment, Narcissa tried to control her breathing.

The sun had almost completely set now. 'Come on, let's get you inside.' Bellatrix breathed as she stood up and helped Narcissa to her feet. Before she had the chance to begin walking to the house, Narcissa grabbed her and pulled her to her lips. They kissed for a long moment before Narcissa pulled away so she could see Bellatrix eyes. She looked right into them. 'Never let him take me Bella.'

'Never.' Bellatrix promised.

She turned and walked to the house; Narcissa took her hand and followed her silently, like a lost little girl.

They made their way to the sitting room and Bellatrix walked Narcissa to the couch. They both sat down together. They again sat in silence. Both of them were thinking about the other one. Bellatrix was thinking about if she had to live without being with Narcissa and Narcissa was thinking about how much she respected her sister for what she was doing and how much she must love her. Narcissa's eyes traced
Bellatrix's beautiful face. Her deep cheekbones. Her big brown eyes. She was the most beautiful woman anyone had ever seen. She had a long dark curl that had fallen and was hanging in front of her eyes. Narcissa lifted her hand and pushed the curl back out of Bellatrix's face. Bellatrix smiled up at her sister. She had been deep in thought and hadn't noticed that her sister had been looking at her.

Narcissa pulled Bellatrix closer to her by her waist. She kissed her again. Narcissa parted her lips slightly and Bellatrix did the same. When they kissed it was like nothing else mattered, like they were the only two people on earth. It was the best feeling anyone could ever imagine. Narcissa's hand moved to Bellatrix's thigh, and starting at her knee, she pulled her hand slowly up Bellatrix's leg. Before she got to the top, Bellatrix had pushed her back and was sitting on top of her. She straddled Narcissa's thighs. Narcissa could already feel the heat coming from under Bellatrix's skirt. She leant over kissing her again, her black curls falling over her shoulders. They were both breathing heavily into the kiss. Bellatrix moved her hands to Narcissa's hair, running her fingers though it passionately. Narcissa moaned slightly, begging for more. Bellatrix released one hand from her hair and moved it down her sisters face, caressing her cheek gently before letting her hand move to her breasts, her other hand still intertwined in Narcissa's hair. Bellatrix felt Narcissa's nipple though her top. She ran her fingers over it, making Narcissa moan again. Bellatrix leant back and pulled off Narcissa's shirt, throwing it aside.

She climbed off her sister seductively, biting her lip and looking into Narcissa's eyes as she got up. Bellatrix stood in front of Narcissa. She had a naughty smile on her deep red lips. Bellatrix knew
what she was going to do and she also knew that it would drive Narcissa crazy! She moved her hands over the front of her corset slowly, still with her eyes on her sister. She traced the black lace with her fingers and reached behind her, undoing the bow at the top. As soon as Narcissa knew what Bellatrix was doing for her, her eyes widened. Bellatrix noticed this and decided to slow down slightly. She stopped undoing her tight corset and instead moved her hand down her hips to her skirt. She bent forward holding the material where her it touched her feet, and looked up giving Narcissa a quick seductive glance and a full view of her breasts in her corset.

Bellatrix took the bottom of her skirt and pulled it slowly up the length of her leg, making sure Narcissa got a good look at what was to be wrapped round her later. She dropped the piece of material and began to pull her skirt to the floor, helping the fabric over her curves and then letting it drop, reviling to Narcissa the lacy black
thong she was wearing. Narcissa couldn't take her eyes off her sister. She could feel her panties getting wet as she watched her strip.

Bellatrix continued teasing her sister. She kept her corset on for now because the way it made her body look was enough to make anyone want her instantly. She looked down to the floor, and then let her eyes find her sister as she smiled cheekily at her. Narcissa couldn't wait anymore so she reached for Bellatrix, but Bellatrix moved out the way of her. She loved teasing her.

'Na ah ah.' Bellatrix teased. 'Wait.' She winked at her and Narcissa sat back again, watching her sister closely.

Bellatrix turned so her back was facing Narcissa. Narcissa's eyes fell to her sisters tight ass. Bellatrix looked over her shoulder to see if she had got her sisters attention, which of cause she did, so she parted her feet a little and bent over, keeping her legs straight and putting her hands to the floor. Narcissa's jaw dropped and she let out a slight gasp. This made Bellatrix giggle. She stood up straight again
and continued. She once again traced the black lace on her corset as she turned to her sister.

'Did you like that?' Bellatrix asked, knowing the answer.

All Narcissa could do was moan slightly, her eyes were following her sisters finger, lightly pressing the lace.

'Do you want more?' Bellatrix questioned, again knowing the answer.

She reached behind her again, continuing to unlace her corset. She kept her eyes on Narcissa, watching as her eyes moved across her body.

When she had finished undoing her corset, she dropped it to the floor. Narcissa's eyes instantly flashed to Bellatrix's breasts. Her nipples were hard, which made her already full breasts look ever better. Bellatrix put her hand behind Narcissa's head and put her lips against hers. Narcissa raised her hands and moved them along Bellatrix's curves. Bellatrix stood up again and watched as Narcissa's eyes fell to her panties. Bellatrix took one step closer to her sister, leaving Narcissa's eyes in line with Bellatrix's tight thong. Narcissa took the fabric in her teeth and pulled it down the length of Bellatrix's leg; she moved to the floor and knelt down, lowering herself to get the material to the floor. She let the thong drop to the floor and raised her head again. Her eyes met with Bellatrix's ass. Narcissa lowered her head again, licking from the middle of Bellatrix's thigh to her tight ass. When her tongue reached her cheek she gently bit it, making Bellatrix jump.

Narcissa moved her hand to Bellatrix's area, but Bellatrix moved again. 'You first Cissy.' She winked again and finished undressing her sister.

When she was done, she pushed all the magazines and stuff off the coffee table. 'Sit down. I want to do something.' She said in a dirty voice.

Narcissa complied, sitting on the edge of the table. As her bare skin touched the marble she jumped. Bellatrix giggled again. 'Now lay back,' Bellatrix ordered.

Narcissa followed orders well, laying back on the table. Bellatrix stood in front of her; she knelt on the floor between her sister's legs and pulled Narcissa closer to her. Bellatrix lowered her head and slowly put her tongue to her sister's clit. Narcissa had never been this turned on before. Her juices were already dripping on to the
table. Bellatrix saw this and lapped it up quickly before returning her tongue to her sister. She licked around her opening a few times before pushing her tongue deep into Narcissa, who called out Bellatrix's name and threw her head back.

Bellatrix moved her hand from Narcissa's knee down her thigh to her clit. She pressed two fingers against it, causing Narcissa to shudder and moan. She pressed harder and began to move her fingers up and down against it. Narcissa was nearing her orgasm. But before she could, Bellatrix moved her mouth away from her sisters opening. 'Squirt for me Cissy,' she said hungrily. 'Cum in my mouth.'

Narcissa couldn't even answer but she heard what Bellatrix wanted her to do. Bellatrix went back to work, this time pushing three fingers straight into Narcissa and using her tongue on her clit. Narcissa moaned louder as Bellatrix got faster. She began screaming out 'Oh god… Bellatrix! Yes! Keep going! Oh my god! Yes!' which made Bellatrix pick up speed, hitting her g-spot. She felt Narcissa start to tighten
around her fingers. Just when she knew the moment was right and Narcissa couldn't hold off any longer, Bellatrix pulled out her fingers and moved them to her clit, replacing them with her mouth and just like Bellatrix has asked, Narcissa came in her mouth. As her sweet juices filled her mouth she kept rubbing her clit and she didn't notice that her sister was building for another orgasm. She kept rubbing, harder and faster and pushed four fingers into Narcissa. She tightened around her, and screamed again. She threw her back her head and pushed her hips up off the table. After her orgasm was over she fell back on to the table, panting.

Bellatrix leant back with a naughty smile on her lips again. She watched her sister try to compose herself. Her eyes were tightly shut, so she used this opportunity to kiss her. Narcissa jumped so Bellatrix must have surprised her. Bellatrix swung her leg over Narcissa and lowered her wet core to her stomach.

'My turn now!' She insisted.
