A/N: Hello! And Welcome to Pinky Promise! This idea has been bouncing around in my head for a while now so I'm happy to post and share this story with everyone. For now this story will be rated T HOWEVER it WILL go into M territory sooner or later. As for the pairing you see in the summary AlicexOCxJasper; this is a polyamorous relationship, meaning equal love for everyone in this triad no more no less. No Oc giving more attention to Jasper than Alice and vice versa. Of course because of the relationship it involves femmslash so classic slogan don't like don't read. Other than that all other parings are cannon and this will be AU Cannon-Divergence so! Sit back relax and please review!

Pinky Promise

Prologue

Five year old Bella could not contain her excitement, Christmas was tomorrow! She wrote her letter to St. Nick and asked for everything she could, the top of her list was a doll that she oh so desperately wanted.

Maybe wishing one more time wouldn't hurt. Bella thought gripping the bed sheets she was comfortable tucked into. Closing her eyes she whispered into the silence in her room.

"Please oh please Satan, if you're listening I really want a doll for Christmas." She squirmed in her bed feeling a strange presence but brushed it off. "Please I would give anything for a pretty doll-"

"Anything hm? Well...wait a doll?"

Bella's eyes snapped open as she heard the voice permeate the silence of her room. Little eyes squinted in the darkness as she took in a figure standing at the foot of her bed. Squeaking in fear she quickly pulled her bed covers over her head, monsters shouldn't be here on Christmas Eve!

Lilith blinked as she stared at the shaking bundle on the bed, she was assorting the souls placed in purgatory when she was summoned. As the devil herself she thought it odd for someone to be calling her on Christmas. Of course there was the usual satanist that she ignored on a daily basis but in front of her now was a little girl who was scared out of her wits. Smelling the salty tears coming from her Lilith softly groaned, this is not how her night was supposed to go.

"Hey, little one, it's okay I'm not gonna hurt you." Even though she knew the girl couldn't see Lilith held up her hands in a pacifying manner. "It's alright." Slowly but surely the child peeked over the sheet taking in the person in her room.

Bella was utterly terrified, this wasn't St. Nick standing before her, from the pictures seen in her books and on T.V she knew what the figurehead of the merry holiday should look like. Before her was a woman dressed in a fancy suit like her daddy wears to special places. Her skin was a dark brown and black eyes held a softness to them. From what she could she in the dark the woman's hair was short, coarse short black curls were close to her head and the sides and back were shaved and faded into the longer locks.

"Y-you're not Satan…" Bella whimpers out. "He's big and old and is supposed to have lots of presents."

Lilith had to hold back a laugh at the predicament, instead she gives Bella a small smile. "Ah I think you mean Santa, little one. Not Satan." Lilith watches as the rest of the covers fall revealing the girl's scrunched up nose, eyes narrowed in concentration.

"Oh."

This time Lilith let out a small quiet chuckle, she couldn't wait to tell one of those snotty elves what happened tonight the next time she got a chance.

"Will you be my friend?" Bella asked suddenly gripping the sheets once more, she always wanted a friend in fact that was the second thing on her christmas list below the doll. The woman blinked at her and tilted her head. Bella continued her explanation. "I don't have any friends and I asked for one for Christmas…"

Lilith was just about to leave when the question came from the child's lips and when she continued her heart seemed to crack into tiny pieces.

Damn my love for children Lilith thought, she watches over millions of souls, albeit suffering and sinful souls; so what's one more living innocent soul going to do? Losing her tie from the suit she wears she smiles and nods at the girl. 'It could be fun to have a friend.' Lilith felt her heart swell when a beaming smile was given to her and now instead of shaking in fear the girl was vibrating with excitement. Holding out a small hand, pinky sticking out she whispered joyfully.

"You have to pinkie promise! If you don't then we can't be friends!"

Lilith raised a calculating brow, but with a smile a long brown pinkie intertwined with a small pale one. Shaking it a few times Lilith felt as if a ice cold bucket of water fell on top of her. Unbeknownst to the five year old Bella quite literally made a friend for life, because once you deal with the devil there's no going back.
