Andromeda smiled widely her head tilting back as she laughed giving Bellatrix better access to her neck, a moan issuing from her lips a few moments later as Bellatrix’s hands trailed up from her hips to cup her breasts.

Narcissa watched her sister’s, her hands balling into fists, her eyes narrowing and her jaw clenching as she stared unblinkingly at the scene unfolding in front of her. It wasn’t the first time she had caught her sister’s in such a position, but it lanced her the same way it had that first time she had happened upon them laughing and touching in some forgotten corner of the house.

Taking a deep, steadying breath Narcissa turned away from her sister’s and headed out of the study walking slowly back towards the living room where the guests were gathered. She’d been sent to locate her siblings who Druella had noticed were absent when they sat down for tea. She’d tell her mother that Andromeda wasn’t feeling well and Bellatrix was taking care of her. Only as Narcissa entered the sitting room again, she decided that she had best switch the story around. It likely would have made Druella suspicious to place Bella in the role of care-giver, and even though her sister’s didn’t see fit to include her in their fun, she knew better than to ruin it.

Two days later …

Narcissa stared at herself in the candlelight watching in her large mirror as the light danced over the pale, elegant planes of her body. She ran her hands over her breasts, cupping them for a few seconds enjoying the warm weight of them, and then she drew her hands down her stomach and around her hips to travel over the soft globes of her ass, all the while tilting her head from side to side looking at her face and body from every angle.

It was confirmed … she was stunning.

Narcissa sighed and turned away from the mirror in a huff, reaching roughly for her nightgown and pulling it viciously over her head before moving over to bed and flopping down on it.

She had checked and she was flawless …as she had already known. She could make boys tent their robes just by walking by them at Hogwarts. In the Slytherin showers she saw the other girl’s from her class glare at her enviously as she bathed, water droplets cascading down the perfectly formed, delicate plains of her body, some of their eyes burning with desire as well as jealousy. She was gorgeous and everyone responded to her in one way or another whether it was a desire to be with her or be as beautiful as her.

It was confirmed … she was extremely desirable.

Moaning in frustration, Narcissa flipped over onto her stomach and buried her face in her pillow, screaming into it loudly a second later though only a muffled sound could be heard in the room before she turned onto her back again and whipped the pillow out from beneath her, flinging it across the room in a rage.

She was just as beautiful as Andromeda, maybe even more so. It could not be disputed. And that being the case she simply couldn’t understand, just could not fathom why Bellatrix didn’t want touch her too.

The next night …

Bellatrix paused as she entered her room aware of something different about the space the moment she entered it. Someone had been inside without her knowledge, she was sure of it. She stared into the darkness for a moment wondering who would’ve been foolish enough to invade her personal space and then her lips parted and she spoke softly, the torches in her room flickering to life immediately.

“Humph,” Bellatrix murmured as her room was illuminated, her eyes landing on her bed, studying the figure occupying it. “Hello darling,” Bellatrix said softly a moment later moving towards the bed, her eyes locked on the pale figure in front of her.

“Hello Bella,” Narcissa replied quietly her throat dry. She was nervous even though she had planned this. Bellatrix could be somewhat unpredictable and she wasn’t quite sure how her sister was going to react to her, though she knew how she wanted her to react.

“You seem to be quite forgetful today,” Bellatrix commented lightly taking a seat on the edge of her bed, her eyes still on Narcissa as she spoke. “You’ve forgotten where your room is and … it would seem, your clothes,” she continued her eyes traveling over her sister’s nude body.

“I’ve forgotten nothing,” Narcissa responded her eyes sharp as they meet Bellatrix’s. “You’re the one with the memory problem.”

Bellatrix lifted an amused eyebrow at this. “Is that so, Cissy dear? And what is it that I’ve forgotten?”

“It would seem that it often slips your mind that you have two sisters,” Narcissa responded her voice cooling a little as she remembered the scene she had stumbled upon between Bellatrix and Andromeda a few days before. “You only ever seem to remember to play with the one,” she continued a silver of anger apparent in her tone. “So I sought to remind you that there is another who desires your affection as well.”

“Ah,” Bellatrix said smiling, laughing lightly a few seconds later. “This is a seduction then?” she asked, her eyes roving over Narcissa anew.

“I shouldn’t have to seduce you at all,” Narcissa grumbled pouting. “I mean, look at me,” she continued running her hands down her body. “How could you not come and take this?” she asked petulantly though she noticed with satisfaction that Bellatrix was looking at her. “But yes, since it seems you needed an invitation … here I am,” Narcissa finished laying back artfully against the pillows she had arranged, offering herself up to Bellatrix’s eyes and whatever else her sister had to offer.

“This is not a game Cissy,” Bellatrix said carefully, lifting her eyes from the perfection of Narcissa’s body for a moment so that she could see her eyes. “This gift once given cannot be returned,” she continued her eyes boring into Narcissa’s making the blonde shiver. “Once you are mine,” Bellatrix drawled smiling wolfishly, “you … are … mine,” she went on punctuating each word. “I will not give you up.”

Narcissa shivered again under her sister’s eyes, Bellatrix’s words coursing through her leaving a trail of liquid heat in their wake.

“I am yours,” Narcissa said finally her chin tilted up proudly though her voice shook slightly. “I’ve always been yours. All that’s left is for you to … take me.”

Bellatrix bit down on her bottom lip, chewing on it softly for a moment as she looked up at Narcissa through lovely dark eyelashes, and then she smiled.

“So be it.”

---

Narcissa’s chest rose and fell deeply, her eyes trained on Bellatrix’s face, gazing up at her as her sister moved up the bed until she was lying along side Narcissa’s body.

“I shan’t be gentle,” Bellatrix said in a disconcertingly gentle tone of voice.

“No,” Narcissa breathed out. “I … I didn’t think you’d be,” she continued half sighing as she spoke, tiny tremors running through her slim frame once more.

Bellatrix smiled and reached out for the blonde, a soft laugh escaping her lips when Narcissa’s whole body twitched at the press of her palm against the blonde’s stomach.

“Didn’t think or hoped, Cissy?” Bellatrix asked a playful lilt to her voice as she looked over at Narcissa curiously.

Narcissa smiled back, her body relaxing a little as Bellatrix absently stroked her stomach.

“Hoped,” she admitted looking at Bellatrix coquettishly through her lashes.

“What a sick, perverted little creature you are,” Bellatrix responded highly amused lifting her hand from Narcissa’s stomach and bringing it up to her sister’s face, tapping Narcissa playfully on the nose a moment later before returning her hand to its previous position.

“Perfect to play with,” Narcissa whispered tension coiling inside of her as she awaited the firm, rough touches Bellatrix had promised her earlier. She knew the calm that existed between them at the moment would not last. She could feel the energy building up within Bellatrix and knew that soon it would be unleashed upon her. But not knowing exactly when Bella’s touches would turn into something else left her anxious … and aching.

“Such an expensive and delicate little toy,” Bellatrix replied her fingers trailing lazily up the side of Narcissa’s torso as an appreciative smile played across her lips.

Narcissa gasped as she suddenly felt Bellatrix’s lips pressed against her, the movement so swift she didn’t even detect it until her sister’s lips were upon her. Bellatrix tongue slipped into her mouth as soon as her lips parted, the eldest Black sister taking immediate possession of Narcissa’s mouth and the kiss, the caress rough and demanding as Bellatrix’s hand closed over Narcissa’s breast, palming the warm mound.

Helplessly, Narcissa’s body began to arch, pushing up into Bellatrix’s hand as her legs twisted on the mattress and her hands moved out in search of Bellatrix’s body grasping desperately at any part of her sister that she could reach.

“What an … eager beaver,” Bellatrix breathed out against Narcissa’s lips, her fingers pressing between Narcissa’s twisting thighs and resting there against the warm dampness of her sisters sex.

Narcissa mewled, biting down on her lip in a way that had to be painful as her eyes met Bellatrix’s hotly, a soft pitiful sound emerging from her throat when Bellatrix pulled her fingers from between her legs.

The next sound to emerge from Narcissa was a startled gasp as Bellatrix placed her hands on the blonde’s thighs and pushed them roughly apart and up, Narcissa breathing in deeply with pain at the suddenness and force with which her limbs were moved.

However, before she could whine or whimper Bellatrix was positioned between her legs, her face hovering just over Narcissa’s sex. She didn’t stay immobile for long, just long enough for Narcissa to process what was happening and what was about to happen, and then Bellatrix lowered her head.

Bellatrix’s tongue was ravenous, devouring the blonde’s sex as a nomad who had been wandering through the dessert for days without water would have gorged himself at the first pond he came upon. She licked the length of Narcissa’s sex in long, firm strokes, pressing her face into Narcissa as her tongue swirled around the blonde’s clit occasionally sucking it into her mouth and nibbling on it with her teeth before licking Narcissa eagerly again and repeating the process.

“When you masturbate do you penetrate yourself?”

Narcissa blinked, her chest rising and falling rapidly as she stared up at Bellatrix’s glistening face. At any other time she should have made some joke about her sister needing a bib, but knowing where the wetness coating Bellatrix’s lips and chin had come from Narcissa could do no more than whimper and buck, her eyes fluttering as she felt more of that same wetness escape from inside of her.

“No,” Narcissa said softly somehow finding the internal resources to be able to speak.

Bellatrix was perfectly still as she looked down at Narcissa after the blonde had spoken, not even blinking, simply prone and staring for what seemed an outlandishly long time to Narcissa and then Bellatrix sighed, her body shuddering slightly as her eyes closed for a few seconds and then opened once more.

“Perfect,” Bellatrix said softly a few seconds after her eyes opened her voice rough.

And then Bellatrix’s hand was between her legs once more, her fingers stroking along the length of her as her sister lowered her wet mouth to Narcissa’s chest, her lips closing over a hard pink nipple, worrying it with her teeth and tongue as her fingers stroked incessantly between the blonde’s legs.

Narcissa’s eyes squeezed shut as Bellatrix took possession of her body, her head falling against and digging into the pillow behind her as her fingers clawed and scratched at her sister’s robed back, her hips canting up into Bellatrix’s hand as she pressed her chest forward begging Bellatrix to take more and more of her.

Bellatrix’s mouth stilled against Narcissa’s breast, her eyelids fluttering in ecstasy as she pushed a finger inside of the blonde, her pelvis pressing down against the mattress as Narcissa’s chocked cry reached her ears.

Bellatrix pressed her face into Narcissa’s bosom, moving her head from side to side, nuzzling against the blonde, trying to burrow into her chest as her pulled her finger out of Narcissa and plunged it in again, pulling out and then entering her again and again as her teeth nipped at the skin of the valley between Narcissa’s breasts.

Narcissa’s hand moved to Bellatrix’s head her fingers tangling in her sister’s dark hair as the pain gave way to pleasure, her lips parted and her hand holding Bellatrix tight against her bosom as her hips bucked up, strangled, excited sounds coming from her as Bellatrix added another finger, and then another.

“Bella,” Narcissa called her orgasm bubbling up inside of her. “Bella,” she called again knowing that she wouldn’t last very much longer. “Bella!” she cried again and then she was coming, her hips vibrating as pleasure wracked her body, her fingers pulling at Bellatrix’s hair in a way the brunette found quite enjoyable as waves of satisfaction rolled through Narcissa’s lithe body.

Narcissa collapsed heavily against the mattress, her limbs heavy as lead.

“Hmm,” Bellatrix hummed thoughtfully, her fingers still buried inside of Narcissa as she moved up the blonde’s body to lie beside her once more, a fond smile touching her lips as Narcissa immediately rolled into the warmth of her body.

Bellatrix curled her free arm around Narcissa’s body holding her for a moment before letting her fingers dance against her sister’s skin in a pantomime of a puppeteer manipulating their creation. “It seems I’ve snapped all your strings,” Bellatrix said regretfully still hugging her sister’s wilted form.

Narcissa smiled pressing her face into Bellatrix’s neck. “No strings,” she murmured softly, content, her body humming happily. “You just need to wind me up again.”

Bellatrix laughed airily. “Perhaps I’ll let my assistant take care of that,” the eldest Black sister responded happily staring out into the depths of her torch lit room. “A reward for the helpful silencing charm she cast just in time to keep Mummy and Daddy from beating down my door to save you.”

“What?” Narcissa asked lifting her head with great effort only to find that Bellatrix wasn’t looking at her even though her hand was still tenderly stroking her. Instead her sister was staring off into the depths of her room.

Narcissa twisted slightly, her eyes following Bellatrix’s gaze, a surprised gasp coming from her a second later.

“What are you doing here?” Narcissa asked scowling, her eyes narrowing as Andromeda began to move towards the bed.

“You were supposed to meet me,” Andromeda said lightly, ignoring Narcissa entirely as she stared at Bellatrix.

“Cissy had other plans,” Bellatrix responded. “She seduced me,” Bellatrix added confidentially a few seconds later, her voice lowering as if she was sharing a secret of the utmost delicacy and importance.

“I told you she was watching,” Andromeda said taking a seat on the edge of the bed.

“So she was,” Bellatrix agreed kissing Narcissa’s forehead after she spoke.

“So,” Andromeda began crossing her legs delicately, her palm moving to rest on the mattress to support her weight as she leaned back casually her eyes finally landing on Narcissa. “Can I play too?”

Bellatrix smiled widely her body jittering against Narcissa’s with happiness.

“Fine,” Narcissa sighed though she eyed Andromeda appreciatively, not nearly as anger with her middle sister now as she had been when she thought Bellatrix preferred Andromeda to her. “But I’m the puppeteer.”

“Tonight at least,” Andromeda replied smiling before she stood up and reached behind her, her robes falling to the ground a moment after that. She then joined her sisters on the bed, presenting herself to them much as Narcissa had presented herself to Bellatrix earlier. “Two cats … so unfair, what’s a little mouse to do?”

Narcissa looked at Bellatrix who smiled and nodded and then turned to look down at Andromeda, settling herself along her middle sister’s side, lording over her as Bellatrix had done to her. She knew exactly what Bellatrix would say in her position.

“Why, be devoured of course,” Narcissa purred enjoying the way Andromeda’s eyes hooded as she breathed in deeply.

However, as Andromeda’s eyes briefly flickered behind her to Bellatrix a knowing and slightly triumphant look passing between them before Andromeda returned her eyes returned to Narcissa’s giving Narcissa the distinct feeling that it had actually been her who was seduced.

The End
