Books and parchment laid spread across the floor, the two sisters sat in the middle of the large room the air stifling, sweat coating the prim and proper blonde, her robes clinging to her lithe body like second skin. The cold sweat trickling between her cleavage, the candle light flickering on her breasts glistening under the weak flames.
"This is getting us nowhere Meda" Narcissa sighed for the umpteenth time that night, slamming shut the dusty tome. "We need a break, we won't be much help if we drive ourselves in to exhaustion".
The dark haired sister warily slumped over, her head resting on her knees. Her robes disappeared long before the dark settled in outside.
"Showing far to much leg Meda" Narcissa suddenly teased, brushing her fingers along Andromeda's bare thigh were her skirt had ridden up bunching around her waist.
Whimpering under the silky fingers dancing across her inner thigh, her legs unconsciously spreading open giving the younger woman better access.
The blonde witch crawled across the gap separating the two sisters, her outer robes dropping into a puddle on the hard floorboards. Narcissa shakily pushed her older sister down on the floor, straddling her waist she leant forward placing a kiss on the tempting pink full lips beneath her.
Lips burned against lips, tongue warred against tongue the fight for dominance neither giving in.
"Tell me to stop" she pleaded, her blue eyes sparkling under the lust. How many times had she found herself breaching the boundaries of sisterly love. Once many years before she had the control to stop the attraction from rearing it's ugly head but now on the point of losing one of her sisters Narcissa gladly accepted the unconventional relationship. Society be damned.
Andromeda swiftly rotated position Narcissa now beneath her. A flick of her wrist both women were now nude as the day they were born.
"Why would I do that little sister?".
Hot fiery lips trailing down the curve of her neck, tongue languishing along her collarbone. A soft moan left Narcissa's lips enticing Andromeda on.
Fingers ghosting over her heaving breasts, nails scrapping her pert nipples hard from her arousal and the chilly night air. Soft warm lips attached themselves to her aching tips, teeth biting down on her right breast.
Narcissa tangled her fingers in Andromeda's dark curls.
The left breast received the same treatment, teeth biting down then a swipe of tongue soothing the sting emitting docile groans from the blonde
A kiss to her inner thigh, another bite left behind.
Whimpering at the teasing bucking her hips to gain friction but her lover wasn't having any of it. Her curls tickling her bare crotch, her teeth biting down hard on her thigh, hard enough to draw blood.
"Please" she breathily moaned.
Grey lustful eyes stared into blue. "Say it" she commanded.
Narcissa shook her head denying her sister the pleasure of hearing her speak her wanton desires out loud. A sharp pinch to her nipple halted the breath in her throat, tears sprung forth at the painful torment.
"If little Cissy wants to cum she needs to say the words" Andromeda growled.
She suddenly reminded her of Bellatrix both sisters demanding and neither cared for the inconvenience of Narcissa's prim and proper attitude.
Andromeda slapped her sister hard across the face. A bright red hand mark left behind, she leant forward kissing away the tears.
"Fuck me please" Narcissa cried out. The pain bordering on pleasure sending warm tingles down her stomach to her sex.
Three fingers shoved violently into her hot dripping sex, the squelching of her vagina echoed around the room. A fast rhythm followed.
Her fingers glistening with her baby sisters juices, shoving them into her mouth she moaned in delight. Sweet and musky just as she remembered.
Grabbing her wand from her robes, Andromeda pointed it at her own wet sex, the wood touching her clit, a shudder of pleasure ran down her spine. Muttering under her breath she abandoned her wand as her clitoris heated up, the tiny bundle of nerves expanding and lengthening out.
Narcissa sighed happily at her sisters new appendage strutting proudly from where her clit once sat.
Andromeda crawled up Narcissa's body, her breasts slightly swinging brushing over the slick skin beneath her. Her hands clutched Narcissa's firm backside allowing the new shaft to slip in with ease right up to the hilt.
An animalistic moan was torn from the blonde's lips, her walls stretching to accommodate her sister.
"Fuck you are still deliciously tight" she groaned into Narcissa's neck. Stilling to allow her to adjust to her new size.
Andromeda pulled up her eyes latching on to Narcissa's, hips bucking frantically. She pulled out leaving the head at the entrance and slowly sinking back into the warm hot depths of her sister.
"Faster! Harder" Narcissa cried out.
She smirked at the frazzled woman beneath her, relishing in the fact she was the one causing the sophisticated lady Malfoy to thrash around like a harlot in heat.
Teasing pace ensured purposely halting the blonde's pleasure from building.
"Fuck me witch" she croaked out.
Slamming back in with force, skin slapping against skin. Whimpers of pain and pleasure sounded from both the women. A shrill whine left Narcissa her legs shaking from her release, Andromeda following shortly after squirting her release deep in her sister.
The smell of sex and sweat lingered in the air. Clothes returned to their rightful owner both women flushed and extremely sweaty.
"I found a book that might be of use". Thrusting the large book on her sister's lap.
"Think Bella will survive if we did this?" Narcissa meekly asked after reading the page that Andromeda bookmarked.
"Either we try and she dies or we sit by and she dies".
"The next full moon is only in a few days Meda are you sure we can get everything prepared by then?".
"We have to. I won't allow Bellatrix to die under the hands of that bastard". Andromeda paced the library stepping on the scattered parchment without much care for their value.
"Think Sirius will help us..".
"We will do it on the grounds of Black hall where the hill meets the woods".
"Our blood and Hermione's freely given... No absolutely not" Narcissa shook her head frantically, her blonde hair whipping around her face. "A sacrifice! who would give their life for Bellatrix to live?".
"I can do this for Trixie".
"I am not sacrificing one sister for the other it is out the question".
"You can not stop me Narcissa..".
"Yes I bloody will. You really think Bella will appreciate your death you stupid cow. She will be lost forever in her insanity" she cried, thumping her fists on Andromeda's chest. "You can't leave me again".
She grabbed the offending hands pulling them above her sister's head. Her lithe body flushed up against the curvy body of Andromeda.
"Okay we will find something else" Andromeda relented feeling the tears soaking her neck from Narcissa. She didn't realise how much her sister had missed her. Maybe there was hope of their families reuniting once more. She just hoped Bellatrix could easily be swayed in letting the past stay in the past.
Breaking apart from the older woman, using her sleeves to wipe away the tears from her face Narcissa smoothly returned to her seat.
The room once again fell into silence as they poured over the books desperately trying to find an answer to their prays.
"A soul bond could bring Bellatrix back" Narcissa excitedly informed her sister.
Andromeda took the proffered book, scanning over the words. Her perfectly groomed brows knitting together in surprise.
"I can do this Cissy" her grey eyes simmering in unshed tears, kneeling in front of her sister, her hands on the shaking knees. "I can make right what I did wrong all those years ago, I can give our sister a chance she never had before". She gripped Narcissa's cheeks.
Narcissa nodded awkwardly. "Promise me you will protect her from harm that will come when the public find out" she pleaded.
Andromeda nodded without a second thought, releasing her sister she stood up.
"That was never going to be an issue I would always protect you both, I always have". Her voice full of conviction and truth.
