In Need

An hour after a rust-coloured fox had scrambled up the bank to sniff at her mate's curled, cold body, the door to the house on Spinner's End snapped again. Two dark figures filled the square of light momentarily before it disappeared, shutting them out in the misty silence.

Bellatrix was as quiet as the crumbled buildings as she stood next to her sister. Narcissa's eyes were still watery and wild, but her mouth was tight and her jaw was set. She pulled up the hood of her cloak, barely sparing a glance for Bellatrix. "Goodbye, Bella," she said and turned toward the remains of the city, back in the direction she'd come.

Bellatrix stood, dumbfounded, for a moment, until it sank in that Narcissa was really leaving and she would need to give chase. "Wait!"

Narcissa was melting into the shadows made by the old houses. Bellatrix put on a burst of speed and caught up with her, tangling her fingers in the folds of Narcissa's cloak. "Cissy, wait!"

Narcissa whirled so quickly that Bellatrix lost her grip and stumbled. Narcissa's hand was out; her fingers were woven around her wand. "Stupefy," she hissed.

Bellatrix ducked, and the spent curse extinguished itself soundlessly on the ground. She laughed and got to her feet, wrapping a hand around Narcissa's slim pale one. "You really think your schoolgirl spells are going to help you now?" she asked, smiling. It must have been a frightening smile, because Narcissa drew back. "When you have just defied the Dark Lord, the greatest wizard the world has known? When you've put your trust in a known traitor?"

"You were our Bonder," Narcissa fired back. "You heard him make the Vow."

"I have heard Snape make vows before. Vows of allegiance, vows of his readiness to join us and do what we will, and then a vow to that fool Dumbledore. And you accept his words, you and our Lord both. What happens when Snape fails both of you?"

"He won't."

"Who will you have then?" Bellatrix lifted her palms to the smoggy sky. "Your husband, who is in Azkaban. And your son, who will have no Snape to protect him from harm."

"I trust Severus." Narcissa's voice was confident but low.

Bellatrix put her hands on her sister's arms, feeling a quiver go through them as she leaned close to Narcissa's flushed ear. "You should be trusting me, Narcissa."

"I shouldn't."

"Excuse me?" Bellatrix backed up so that Narcissa's whole face was in her line of vision. Narcissa's eyes were slits and her mouth was still compressed, giving Bellatrix the eerie impression that she was looking in a mirror.

"You have no son. And your husband – " Narcissa stared at the ground, and Bellatrix tightened her grip on the small forearms, buried deep in layers of cloak and robes. Narcissa's words were steady, but her voice was shaking the way it used to when they were small and Bellatrix would impress her sisters with tiny spells: spilling butterflies out of trees, igniting flowers with a whispered word, listening to adults' confident conversations behind closed doors. Andromeda would frown, Narcissa would cry, and Bellatrix would laugh, she remembered. Now, listening to Narcissa, thirty-five years later, she felt like laughing again.

"And you don't care if your husband sits in Azkaban," Narcissa finished defiantly.

Bellatrix did laugh now. "My husband? My husband sat in Azkaban for fourteen years, Narcissa, don't you remember? I'm sure you missed us while you were sweeping about in your dear manor, but we were the faithful, Cissy. The Dark Lord needed us, and so do you."

"I don't." Narcissa's voice was small.

Bellatrix remembered being four years old and staring down at the swaddled new baby, who looked like a round ball with nothing visible but blue eyes that blinked, foggy and unfocused. The baby cried, and Bella picked it up, hugging it and whispering of the things they would do when they were grown until it snored and drooled against her shoulder. "You do, Narcissa," she said, remembering the way the baby bounded after her, refusing to eat or play or sleep without her oldest sister. "You always have."

Narcissa opened her mouth again, and Bellatrix closed it with a slap that bounced back and forth between the dilapidated brick alley walls.

"You remember," Bellatrix said, tracing the faint red outline on her sister's pale cheek with first her thumb and then the heel of her hand, "when we were young."

Narcissa bit her lip, the tips of her teeth glowing white against her pink mouth. "Yes."

"When I left for Hogwarts, and you cried."

"Yes."

"When Andromeda proved that she was neither Black nor Slytherin material."

"Yes."

"And when you proved that you were."

"Yes."

"What did you tell me, your first night at Hogwarts?" Bellatrix trailed her finger down the angry curve of Narcissa's jaw, tucking some of her sister's pale hair behind her ear.

"I – I don't remember."

"Liar. You do." Bellatrix's thumb found the hollow of Narcissa's throat, right between her collarbones. "You told me you'd missed me."

Narcissa's blue eyes fluttered. "Yes."

Bellatrix pressed lightly at the dip between the bones, tasted the sound of Narcissa's gasp. "You will need me when Snape fails you, Narcissa."

She didn't wait for an answer before she leaned forward to kiss the pale skin on Narcissa's neck, but she got one between little nips and bites against Narcissa's mouth and throat and ear. "Yes," Narcissa breathed, and Bellatrix felt her sister's slim hands reach up to tangle themselves in her hair. "I'll need you."

Bellatrix gave Narcissa a shove, and her sister's slim body hit the brick side of the alley with a soft thump. With her hand she stroked the curve of Narcissa's neck, the fall of her cloak from her shoulder, the sturdy bone right behind her shell-shaped ear. It was odd that Narcissa was now taller, reaching down just slightly to hold Bella's face between her hands. It was odd that Narcissa had married and had a child, but under it all she couldn't lie: it was Bella she needed.

Her sister's skin was soft and sweet, with the barest taste of salt from her fear and anger. Just behind her neck was a small puckered mark that she'd gotten one year playing Death Eaters and Muggles with Bella and Andromeda, but other than that, Narcissa's face and neck and throat were perfect. Not like Bellatrix, who spent too many years curled up against cold stone in Azkaban, who still felt the illusions of rats and icy sea spray against her skin no matter where she was.

Bellatrix unfastened Narcissa's cloak and let it fall in a heap on the dusty pavement; she slid her right hand inside Narcissa's robes, cupping the hidden skin of her breast. She would have liked to keep Narcissa pinned against the wall, but she didn't have the luxury of another hand, so she pulled out her wand and dredged up a spell she hadn't used in years, one that whispered cool, silvery cords around Narcissa's wrists and legs. No one could say that Death Eaters were all work and no play.

It was play, actually, she thought as she watched Narcissa's face. Most active were her sister's eyes, the same shade of blue that Bellatrix remembered from the baby in the bassinet. She pinned Narcissa's gaze with her own, then teased both hands over her sister's breasts, pulling them free and skimming her palms up over the nipples. The mist hung around them, as silver as Narcissa's hair, and when Narcissa shivered, Bellatrix discovered an expanse of gooseflesh under her fingers.

She threw Narcissa's robes back just enough that she could see her sister's chest, starkly pale against her black robes, almost as light as her hair. Bellatrix steadied herself against Narcissa's hip and leaned down to take one nipple in her mouth; there was another little thud as Narcissa's head tipped back against the wall. "Bella," she said hoarsely as Bellatrix circled her tongue and teeth around the small bud of flesh, feeling it grow harder with every damp flick of her tongue. Narcissa tasted like vanilla and dust and distraction, but not enough distraction to keep Bellatrix from reaching for her wand again and landing a whistling smack to Narcissa's thigh.

She felt, rather than heard, Narcissa gasp and grit her teeth. Bellatrix loved her wand – thirteen inches, oak – but something slightly more flexible would make a more satisfying sound and stinging against Narcissa's skin, would have made her breathing speed up even more than it was now. Still, it would have to do. She dug the point into the soft spot just above Narcissa's hip. "You seem to have forgotten much in those thirteen years with your traitor husband," she said, cupping Narcissa's other breast with her hand and rolling the nipple in the small half-oval between her thumb and forefinger. The small choking sound that Narcissa made was more than enough grounds to hit her again, harder this time, so that a small red line bloomed on Narcissa's leg. "You need me. I need you to – "

"Make no sound," Narcissa finished meekly, obviously torn between wanting to comply with Bella's wishes and wanting to prove that she hadn't forgotten everything. Her eyes squeezed shut again as Bellatrix pinched her nipple with precise, pointed fingertips. She took in a sharp breath, but that was all. She didn't say anything else.

"That's right." Bellatrix bent to lick Narcissa's other breast, feeling the angry heat of her nipple between her lips. "It's better if I don't have to gag you, isn't it, Cissy?" She thrust one robe-clad knee between Narcissa's legs, eliciting another gasp. "But any more sounds like that and I'll consider you woefully out of practice."

Narcissa nodded, and some of her long, loose hair spilled down her bare chest, brushing Bella's cheek momentarily. Bellatrix wound it around her wrist and shoved it back behind Narcissa's shoulder. "I wouldn't have thought you'd forget," she said, dragging her wand across Narcissa's flat stomach, just under the dip of her navel, and down between her legs. The tip disappeared against Narcissa's wetness, and her sister bit her lip. Bellatrix watched her face as she knelt on the puddle of Narcissa's cloak and leaned forward to kiss Narcissa's hip and stomach. "There are things we all must remember, Cissy," she said, her breath tarnishing the milk-coloured skin.

She traced her sister's folds with her mouth and wand, thrusting the tip inside Narcissa slowly but confidently. Bellatrix wrapped one hand around Narcissa's tightened thigh to steady herself and licked at the small, salty bud just below the silky blonde hair while she guided her wand inside Narcissa. She tilted it in a small, tight circle, and Narcissa made another, guttural noise, like a gasp she'd tried to swallow. Bellatrix fisted the wand in her white-knuckled gasp and concentrated on a wordless Lumos that made the slender oak stick glow and crackle and a jolt move up through Narcissa's body. Narcissa's eyes went wide and her mouth parted slightly, her tongue flicking out to lick her top lip. Then her eyes closed again as Bellatrix stretched up to lick the nub of her clit with small, insistent strokes.

This part was always the same, Bellatrix remembered, and she hoped Narcissa did too. "What do you want, little sister?" she asked, every word dripping with Narcissa's wetness, the one time she was granting Narcissa permission to talk.

"You," Narcissa said cautiously, and then her voice grew stronger, "please, I want you."

"And what else?" Bellatrix asked, her words humming against Narcissa's clit.

This was new, and Narcissa paused, apparently unsure of what to say. Bellatrix waited too, feeling the tension gathered in Narcissa's muscles, ready to explode with another dive of her wand. "Well?" she asked, stilling her grip on her wand.

"Please," Narcissa repeated, sounding close to tears.

"Tell me," Bellatrix said, sliding out of Narcissa and standing up so that they were level again. She gripped Narcissa's chin in her palm and brought their mouths together, sharing the hot metallic taste that coated her tongue. Her fingers hovered over Narcissa's clit. "Tell me – "

"I need you," Narcissa blurted out, her words thick against Bella's mouth, and Bella plunged two, then three, fingers between her sister's legs, into all the damp spots where her wand had just been. The crook of her thumb brushed roughly at Narcissa's clit, and then her fingers were tight and slick and impossible to move as Narcissa came, dripping onto Bellatrix's hand and pooling in her palm.

Bellatrix kissed the corner of Narcissa's mouth as she withdrew her hand, feeling the misty air sweep around it. It was enough to make her shiver as she backed away from the wall and scooped up Narcissa's cloak, handed it to her, and unspelled the silver ties that were keeping Narcissa's hands and feet in place.

Narcissa made a big show of readjusting her bra, pulling her robes back over her shoulders, pushing back her hair. "Don't you want – " she began awkwardly, taking her cloak from Bellatrix and wiping the spot just below her mouth.

Bellatrix shook her head and watched Narcissa's blue eyes cloud cautiously, the expression crawling over her features as well. "Cissy," she said, putting a hand around her sister's slender waist. "You need me." She leaned forward, her lips brushing Narcissa's earlobe. "But I don't need you."

As Narcissa's mouth found the side of her neck, Bellatrix prayed to Merlin that she was right about Snape.
