Notes: It's an adaption of my short 'Who?' prompted fic, which was requested to be longer. This is a sort of finished fic, well, it is finished. I think. It's got a very natural ending, and I like it, but part of me wonders whether to continue it, even though I have a lot on (i'm taking part in a lot of fests/fic exchanges). Anyway, opinions would be nice please :)

“I need to go, Cissy,” moaned Bellatrix, getting up from bed and getting dressed, or rather, simply waving her wand.

“Oh, Bella!” whined Narcissa, pouting her lips and sticking out her chest.

“I need to get back to Hermione – she's expecting me,” Bellatrix kissed Narcissa once more. She'd told Hermione, her lover, that she was going shopping, but she'd really spent the afternoon in her sister Narcissa's bed, having passionate, guilt-free sex.

“Ugh, her again. Why don't you just leave her?” Narcissa leant back against the bed, agitated at her sister's choice of lover.

“Because I love her, Cissy.”

“Then why do you fuck me?”

“You're my addiction,” smirked Bellatrix, blowing Narcissa a kiss and leaving.


-------------------------------------------------------------------------------


“You're late,” said Hermione sharply, as Bellatrix hurried through the door.

“Sorry, there was a queue...” Bellatrix put the shopping bags on the table and Hermione turned around to start cooking, ignoring Bellatrix's offer of a kiss. Bellatrix rolled her eyes and went upstairs to have a shower. Hermione had dinner on the table by the time she came down.

“Thanks, my love,” smiled Bellatrix.

“You're welcome,” snapped Hermione; she wasn't in a good mood.

“Alright, what's wrong?” Bellatrix dropped her fork, getting all the more irritated by Hermione's sharp attitude.

“Ron.”

“Ahh,” Bellatrix nodded her head, knowingly.

“He still can't accept us.”

“Just forget him,” said Bellatrix, eating some of Hermione's cooked fish. “We've been together five years now, Hermione. If he hasn't gotten over it by now, I don't think he ever will.”

“Maybe you're right,” mused Hermione, taking a forkful of fish too.


-------------------------------------------------------------------------------


“Do you love me?” whined Hermione, as she curled into Bellatrix's arms that night.

“Of course,” smiled Bellatrix, stroking Hermione's hair and kissing her forehead.

“I saw Lavender today. She's just broken up with Dean, apparently he had an affair with Padma Patil!” gasped Hermione.

“Oh,” muttered Bellatrix, feeling a little guilty about her pleasure time with Narcissa.

“Draco just got promoted,” commented Hermione, nuzzling her face into Bellatrix's breasts.

“Yes, I heard.”

“Oh?” asked Hermione.

“I saw Cissy today, out shopping,” Bellatrix quickly thought.

“How's she doing? After Lucius and all...” Lucius had been killed in the final battle, and Narcissa had been distraught ever since.

“She's alright. Trying to piece her life back together.”

“I can imagine,” Hermione had always felt sorry for Narcissa, but the two women had never got on. Narcissa, like Ron, was another who couldn't accept their relationship, but Hermione wondered why when her own son, Draco, had married outside of her plans, and she had been happy for them.


-------------------------------------------------------------------------------


“Hey lover,” called Narcissa, hearing Bellatrix come through her front door. She was naked in bed again, awaiting her visitor.

“Cissy,” Bellatrix called back, stripping off her clothes before she had even made it to the bedroom. By the time Narcissa saw her, she was wearing nothing but sexy, black lingerie that Hermione had bought her last Christmas.

Narcissa's face beamed – she loved it when Bella wore items that Hermione had gotten her. It just felt all the more wrong.

Bellatrix stripped the rest of remaining clothes for Narcissa, dancing sexily as she did so, and Narcissa pulled back the bed covers to reveal her naked body.

The two sisters couldn't contain themselves any longer and Bella dived straight into bed with Cissy, kissing all over her body, quickly making her way to Cissy's beautiful pussy. Bellatrix had never been one to hang about.

Narcissa moaned as Bellatrix stuck her tongue straight into her cunt her tongue going as far into her vagina as possible. Bellatrix lapped and sucked, licking all around her labia and finally up to Cissy's clit. This drove Cissy wild, and she grabbed onto the headboard, breathing heavily; her head moving about wildly.

In no time at all, Cissy was exploding all over Bella's mouth, and Bella didn't hesitate to lick it all up.

After a swift recovery, Cissy straightened herself up. “Let me do you,” she smiled at Bella.

“No.”

“You always say no. Why not?” frowned Cissy.

“It's Hermione's.”

“You know she wouldn't be able to please you like I can,” Cissy licked her lips in Bella's direction, but Bella just got irritated and rolled her eyes.

“Please yourself then,” remarked Narcissa, turning over to face away from her sister. Before Cissy knew what was happening, Bellatrix had left, slamming the door behind her.


-------------------------------------------------------------------------------


“I saw Draco again today,” said Hermione, just getting in from work and taking her coat off. Bellatrix was sat at the kitchen table, reading a magazine. Hermione and Draco worked at the Ministry on the same floor, so they often bumped into eachother. “He told me about your gathering coming up. Said we were invited.”

“Oh, i'm not so sure I want to go...” Bellatrix trailed off, afraid of Narcissa and Hermione being in the same room. After all, Cissy could be a jealous little thing and she wouldn't put it past her sister to bring as much discomfort to Hermione as she could muster.

“Come on, it'll be fun. Maybe me and Narcissa can build bridges,” suggested Hermione, now cleaning the kitchen surfaces.

“Maybe,” replied Bellatrix, fully knowing how Narcissa would act should the two ever come into contact.

“Well, I told Draco i'd let him know tomorrow, so Narcissa can set the guest list. It's this weekend, you know.”

“Okay, fine. If it means so much to you, we'll go,” snapped Bellatrix.

Hermione beamed; she did want Narcissa to like her and for her to accept that she and Bella were a couple, and a serious one at that.


-------------------------------------------------------------------------------


“Do I look okay?” asked Hermione, trying on her dress for the evening. The time had rolled around for the Lestrange/Malfoy gathering and the two women were getting ready. Bellatrix was putting on her make up while Hermione was deciding what to wear.

“You look lovely, dear,” smiled Bellatrix, glancing over at Hermione. She looked a picture in the pretty pink strapless dress – Bella had bought it her some while ago. Actually, it was just after an escapade with Cissy, and she'd felt quite guilty about it.


-------------------------------------------------------------------------------


“Bella!” smiled Narcissa, opening the door to the couple. Narcissa hugged Bellatrix then turned to Hermione, “and you brought your mudblood.”

“Narcissa!” reprimanded Bellatrix; she hated it when Narcissa was cruel to Hermione.

“No, it's alright,” Hermione interrupted, taking Narcissa's hand and shaking it. Narcissa grabbed her hand out of Hermione's and let the two in, taking them to the drawing room. Bellatrix, embarrassed at her sister's behaviour, smiled apologetically at Hermione and took her hand, squeezing it to reassure her.

“Aunt Bella, Hermione,” greeted Draco. Hermione would never have thought it, but he really didn't mind the two being together. He'd even confided in Hermione that he wished he and Astoria were that close.

“Draco!” Bellatrix hugged him, and Hermione the same afterwards.

“Come, you must meet Astoria,” he led them over to a woman in the corner. They'd met her before, so were quite surprised at this offer, but followed him anyway. Astoria stood up and Draco put his arm around his wife. “We're having a baby,” he said excitedly.

“Congratulations!” squealed Bella and Hermione.

“That's brilliant news, you two,” smiled Hermione.

“Thanks,” he grinned, and kissed his wife on the cheek.

“Should've know the mudblood would be pleased,” Narcissa snuck up behind them. Bellatrix rolled her eyes.

“Mother!” reprimanded Draco; he was clearly upset by his mother's actions too.

“It's alright, it's fine, really,” Hermione said.

“You know, you're such a stuck up little bitch. It's like nobody can do anything to annoy you. I know what'd get the bees in your bonnet though,” she smirked at Hermione, and Bellatrix fiercely grabbed her arm and led her away.

“What are you trying to do, Cissy? Ruin my relationship? You know, if you behave like this i'm going to have to call us off.”

“Oh give me a break. Relationship? With a mudblood?”

“Yes, relationship. And don't call her that.”

“You used too, once upon a time when you were a proper member of the Black family.”

“I grew up,” retorted Bellatrix, turning away from her sister and rejoining Hermione.

“Are you okay?” Hermione asked.

“Yeah...”

Narcissa was furious at being spoken to like that; she felt humiliated that her own sister would choose a mudblood over herself and vowed to get revenge. Grabbing a glass of champagne from a house elf, she made her way over to Bella, Hermione, Draco and Astoria. Narcissa took a large swig and exploded.

“You think you're so high and mighty, mudblood, but listen here. Your little princess isn't as pure as you thought she was,” Narcissa revelled in Hermione's shocked face and Bellatrix's pure anger.

“What do you mean?” asked Hermione.

“Cissy, don't do this,” begged Bellatrix.

“No, it's time she knew,” Narcissa took another sip, “and I mean that your Bella isn't faithful. Oh no. She's been shagging me,” Narcissa grinned. Hermione's face dropped, tears formed in her eyes and she looked straight at Bellatrix.

“Is this true?” she asked, hurt and upset in her voice.

After some time, Bella answered, avoiding Hermione's gaze. “Yes,” Bellatrix didn't want to lie to Hermione any more.

“Oh, and you know the lingerie you bought Bella? She wears it when she fucks me,” Narcissa laughed and walked away. Draco and Astoria were looking at the floor, they didn't know what to do.

Embarrassed and ashamed to have found this out in front of so many people, Hermione left the grounds of Malfoy Manor and apparated back home.

Bella followed, but just before she did she caught up with Narcissa and slapped her, hard around the face, “You evil, little bitch. How could you?”

“I'm a true Black. And you were the one shagging your sister behind your mudblood lover's back!” Narcissa laughed.


-------------------------------------------------------------------------------


Bellatrix turned away; she too left the grounds and apparated home to find Hermione lying on the sofa, crying.

“How could you?” were the only words spoken by Hermione, still sobbing.

“I'm sorry, love,” pleaded Bellatrix, “you've got to believe me, it didn't mean anything.”

“Believe you? How am I supposed to trust anything you say anymore Bella?” Hermione sat up straight. “The one person in my life I thought I could rely on, the one person I thought I could trust and who loved me betrayed me for her own elitist sister.”

“I do love you.”

“Funny way of showing it,”scoffed Hermione. “If I knew incest drove you wild I never would've gotten together with you.”

“It's not like that.”

“Yeah? Well what is it like then? Did she beg you, is that it?”

“No, well, yes, I...I never let her touch or play with me. I always told her it was yours, and it still is.”

“Well that makes it alright now you've told me that all you did was shag her,” screamed Hermione.

Bellatrix hung her head in shame, she was utterly embarrassed by what she'd done, and the reality of it all came screaming towards her.

“Oh, now you feel ashamed. Bit too late there, dear Bella,” Hermione stood up and started pacing up and down the room. Bellatrix tried to take her hand but Hermione pulled it away from her grip. “Don't you even touch me, you sick, little, twisted PERVERT!” she screamed, grabbing her coat and walking out the door – slamming it shut behind her.
