Black Diamond

CHAPTER ONE

Twilight coughed as the thick layer of dust peeled away from the shelf as she pulled the old book from the shelf of the ancient bookcase before sneezing. "Ooh bless me. I'm nearly done Rarity, thank you so much for helping me out today. I've managed to get twice the work done in half the time." She said gleaming to her unicorn friend.

Rarity finished putting the last of her pile of books down before shuffling the dust out of her mane with her magic. "Ohh it was no bother at all Twilight darling. It's the least I can do after you took the time to help my Sweetie Belle with her chemistry revision. I was almost certain she would fail, especially since she's started spending time with that colt in her class lately..."

Twilight giggled interrupting her. "Ohh Rarity, was it so different when we were her age? Surely there was a special somepony you had a crush on...right?" Twilight saw Rarity's sullen look and sensed that she had said the wrong thing.

Rarity thought for a few moments, there hadn't been anypony because she had been so wrapped up in herself so much that she'd missed out. "Not quite...you see Twilight, I'm the Lady I am today because I've had to work hard and sacrifice a lot to become this amazing fashionista that I am today." She said trying not to make eye contact with Twilight.

Twilight sensed her friends bravado over her discomfort on the matter and kindly reverted back to the subject at hoof. "Okay Rarity, that pile of books you have, they're all going in the vault. That's where we put all the outdated subjects such as dark magic, the old ways and suchlike go, as in they'll never be used again."

Rarity tilted her head to one side gawping at her friend. "So they just go into storage for ever? But this one is so pretty and look at it, it even has a diamond embossed on it's plush blue cover." She said almost pleading it's case. Twilight thought a moment before softly rolling her eyes. "Okay Rarity, you can keep it. I don't see why not, take it as a token of my appreciation. It looks like the spells are outdated but I know its in safe hooves with you." Rarity's smile beamed through her eyes. "Ohh thank you Twilight! That's so kind of you." She carefully picked the book up in her magic and placed it in her satchel before picking up the pile of books in her magic and following Twilight down into the vaults.

Sometime later Twilight and Rarity had left the library accompanying each other halfway before parting for the evening. "Well Rarity, this is me. Thanks again for all your help today." Twilight smiled as she turned down the track. Rarity glowed. "Glad to be of help and thank you again for the lovely book, I've got just the place to put it."

As Rarity trotted back towards Ponyville she thought back to what Twilight had asked her, if she'd had a special somepony back in the day making her wonder for a few fleeting moments of what might have been. Like the colt who used to sit beside her in class, and how he would hold the door open for her and other little things that matter. She snapped out of her musings and sighed rolling her eyes at herself. "Why should that matter now for goodness sake? I am a self-made mare and a successful one at that." She shook her head discarding the silly hypothetical notions. She could see the Carousel Boutique just up ahead she hurried across the empty street and headed straight inside. She dropped her satchel on the kitchen table and trotted upstairs to run a hot bath to wash away the days dirt and grime.

She stepped into the hot bath and melted under the bubbles closing her eyes and becoming one with the water. As she started washing herself down it wasn't long before her hooves started wandering over her elegant curves, caressing her plush belly and rubbing her hoof over the fullness of her tender crotchteats which were starting to poke out from the water with her rising arousal. She gasped as the soap slipped from the grasp of her magic sliding it's way down her tender nether lips, almost making her moan aloud as the slick soap tickled her open slit. She moved a hoof to her throbbing bud as her mind raced with her wildest fantasies and soon found her hoof slick in her juices. She bit her bottom lip hard imagining a long thick phallus penetrating her soft wet folds..."RARITY! I'M HOME!" Sweetie Belle called out from the top of her lungs. Rarity's mood died instantly rolling her eyes as her little sister continued with her bellowing. "I brought Rumble back, we're doing a class project together...I hope that's okay?"

Rarity sat up in the bath calling back through a fake smile gritting her teeth. "I'm in the tub Sweetie darling! I'll be right down!" She closed her eyes inhaling deeply taking in one more moment of tranquility before stepping out of her bath grabbing her fluffy white gown with purple trim then wrapped a towel around her mane then stopped giving a thought to how Sweetie Belle had said she'd brought a boy home and grinned softly allowing herself that giddy filly feeling that she missed out on those years ago. "No harm with a little tease I suppose." She mused to herself as she whipped the towel back on the rack letting her wet mane flow down giving it a quick brush on the way to the stairs.

Rarity knew exactly where her little sister would be by now, in the kitchen raiding her cupboards for milk and cookies no less. As she got to the doorway she gasped and stepped to the side as she was taken aback on seeing Rumble up on her sisters back. They were laughing and giggling as Rumble made exaggerated chomping noises whilst nibbling Sweetie Belle's ear. Rarity could see Sweetie Belle's tail lurched to one side before Rumble slipped to one side hanging on her hip and Rarity could see him slipping from his sheath with excitement.

She carried on watching them from the jar of the door thinking of how she never had anything like this when she was their age. Her mind swirled with questions. "Is this even normal? Should I be allowing this? Oh my little sister is growing up so fast." Rarity anxiously thought to herself.

Watching a little longer as Rumble slid to one side and was now grinding against Sweetie's hip and was enjoying it a little to much for her liking despite feeling something stirring inside herself as she watched the young couple. Rarity took a deep breath and walked in as if she hadn't been watching them for the last five minutes. "Ahh Sweetie darling, there you are! Have you eaten...ohh my, who is this handsome fellow, aren't you going to introduce us?"

Sweetie Belle blushed with the thought of her sister catching them in this compromising position. "Uhm Rarity..." Not sure on which to say first, apologies or introductions. Rarity smiled and stepped forward. "I do apologise for my tardiness, I wasn't expecting company. I am the Lady Rarity, Sweetie Belles big sister and you are?"

The young pegasus blushed and gulped looking at the beautiful mare before him. "I..I'm Rumble..It's nice to meet you." He said trying to keep his cool as the wet maned mare fluttered her eyelashes at him provocatively as Rarity smiled softly. "I wasn't expecting company tonight, however you are more than welcome to stay for supper. I'm just about to start." Rumble and Sweetie looked at each other and were about to answer in unison when Rarity decided for them. "It's settled then, dinners at seven. I'll start setting the table. Now run along and get started on your school project!" She said smiling widely at the young pair.

The three stood in confusion a short moment before Rumble broke the silence. "Uhhm Lady Rarity, err where's your bathroom?" Rarity cleared her throat. "Why it's straight up the stairs and first door on your right." The colt nodded a nervous thanks before trotting off.

Sweetie Belle watched him head up the stairs and out of earshot before confronting her big sister. "Rarity! What are you doing?" She frustratingly asked trying to keep her voice down. Rarity was taken aback by her sister a moment. "Well Sweetie, I thought that's what you would like darling...Unless you would prefer me to kick him out and then send you to your room for dry humping in my kitchen, would that be better?" Sweetie gasped, she hadn't realised that Rarity had caught them misbehaving. "Y-you saw that Rarity? I-I..."

Rarity put a hoof gently to her sisters cheek. "Sweetie Belle, my darling. I am your big sister and sometimes I also have to play mother whilst you're in my stead. But you see, I've never had what you have in your life right now. I've never had a special somepony and didn't have any real friends until I moved here. Uhh, what I'm trying to say Sweetie Belle, is that I'm on unknown ground here as on how to act and guide you, but I know you have something special with your new coltfriend and you both have something I have never had. So, all I ask in return from you is...just keep it to the 'dry' humping okay? I don't need another foal cantering around to be looked after." She said softly smiling at her precious sister as she ran her hoof through her mane. "You're growing up so fast."

Sweetie looked up lovingly to her sister. "Thank you Rarity, You're the best sister ever and I promise that I will be careful." She said hugging tight into her big sister. They broke their embrace hearing Rumble trundling back down the stairs taking the time to recompose themselves.

Rarity whipped her wet mane away from her eye. "Okay you two, off you go to study now and remember, not to much funny business up there though...you don't want to ruin your appetite!" Rarity giggled as the couple headed upstairs blushing.

Later

Rarity had prepared one of her favourite meals for dinner, the pans were bubbling and brewing nicely as she began to set the table. She stopped and bit her lip as she heard Sweetie and Rumble laughing as well as a few squeaks from the bed here and there. She sighed wondering if she was doing the right thing before continuing to set the table. It was then she saw her satchel with her lovely new book poking out, she checked the pans and found she had some time to peruse through it before the food was ready.

She placed it down in front of her, inspecting the soft blue of the old leather cover with the black embossed diamond dead centre. She was quite excited as she knew she was going to be the first pony in a hundred years to look upon it's pages. Her horn glowed as she carefully opened it, before carefully and slowly turned the pages. Her eyes widened upon finding a multitude of various spells and incantations.

She was thrilled with such a find, she read one for worn hooves, a herbal tea for coughs and sneezes and even a remedy for estrus pains. She smiled in wonder at the various concoctions she could use to help her friends as she eagerly turned the pages before stopping abruptly. "Noo..could it be? Is that even possible?"

Her eyes were glued wide to the words on the page reading out under her breath. "Age manipulation??" She intricately read through the two pages studying the old wording not believing her eyes or her luck, she then snapped from her thoughts when she heard the pans bubbling over. She used her magic to turn the hob off then packed up the book back into her satchel and hid it in the cupboard under the sink. "Sweetie! Rumble! Dinners ready!"

Sometime later the three ponies had finished their delicious meals and were sitting relaxing at the dining table with full bellies. Rarity had kept the conversation going asking them various questions about their school project such as whose idea it was? What made them choose it and suchlike, but now they were full and sleepy as the night drew in Rarity asked them more personal questions. She made eyes at the colt from across the table taking a sip of her wine watching him stir uncomfortably in his seat watching the seductive mare before him. "So Rumble tell me, how did you and my Sweetie Belle meet?" Sweetie Belle choked on her juice. "Rarity!?"

Rarity chuckled taking another sip of wine. "Oh shush darling, I'm simply asking our handsome guest a question. So Rumble, you were saying before we were so rudely interrupted." Rumble's eyes darted between Sweetie Belle and Rarity. "Well...w-we met on a field trip. We were paired up to take notes on the flora and fauna and found that we had a lot in common with each other, then we started lunching together where we decided to team up for the school project and now we're...uhh here...having a dinner with you which was really tasty by the way! Thank you Lady Rarity for inviting me to stay." Rarity put down her glass and smiled at them both. She found it nice to have company over especially with one as handsome as Rumble.

Rarity broke from her musings when a branch blew through the kitchen window sending the howling wind and rain into her home. Sweetie and Rumble cried out and jumped under the table where Rumble used himself as a shield laying over Sweetie Belle. Rarity had already jumped to her hooves and was using her magic to push the branch and the storm out of her kitchen whilst repairing her window. The wind flayed her mane around as she gritted her teeth fighting against the wind which was making her eyes water then within minutes the kitchen was back to normal.

Rumble opened his eyes to see Rarity's face up close and personal, she had put her head under the table to check if they were alright. Rumble stared mesmerised, the warm snorts of air from her nose caressed his face, watching as her lips slowly curved upward into a soft smile and there was something about the softness of the pink blush across her snow white fur, with her big beautiful blue eyes staring into him. It seemed like forever until she spoke. "Rumble? Rumble? Are you with me? I asked if you and Sweetie are alright?" Rumble shook his head back into reality. "Ugh yes...yes we're both fine thanks." She helped them out from under the table and dusted them down. "Well thanks to you, my little sister is safe, it was very noble of you to protect her the way you did." He blushed as she ruffled his mane. "Well it doesn't look as if you'll be going home in this storm tonight Rumble. Do your parents know where you are?"

Rumble looked at her realising that he was more than likely staying there for the night. "Yes Lady Rarity...its just they probably didn't think I'd be staying out over night." Rarity put a hoof on his shoulder. "Not to worry darling you'll be safer in here than out there in that terrible storm and you can just call me Rarity from here on out, okay?" Rumble looked at her a moment. "Okay Lay.....uh yes Rarity." She smiled tussling his mane again. "Now then, you two can get back to your project and when it's bedtime I'll show you to the guest room." She said smiling.
"Thank you Rarity, I won't be any trouble, I promise." Rarity walked them towards the stairs and turned to Sweetie Belle as Rumble headed up the stairs and whispered. "You've found a good one there darling, I'll give you an extra hour with your bright knight before lights out." Giving her little sister a knowing wink. Sweetie blushed giving her sister a quick squeeze before cantering up the stairs after Rumble not wanting to waste another minute.

Rarity returned to the kitchen to clean up the dishes whilst humming a harmonic tune to herself. After everything was cleaned and stored away she sat back down and finished her glass of wine her horn lit up as she used her magic to bring over her satchel intrigued by the notion of being able to turn back the clock so to speak.
She once again found the page with the spell as she gave it a good read through, there didn't seem to be any price or penalties of any kind to pay for using such magic. She was about to try it out only she couldn't let Sweetie or Rumble see, she needed a plan. She and the filly could not be seen in the same place and she had the right idea for just the thing. "Ideaaaa!!" She called out as Sweetie Belle's bed springs started bouncing again, along with the visions of what they might be doing. She shook her head and took a deep breath "Okay, I'll say I need to go out of town unexpectedly the day my estranged cousin will call for a visit...hmmm then again Sweetie Belle might get suspicious. Also I need somewhere to stay whilst I'm out of town...hmm there's the old abandoned shack along the old track, it's a bit worn down but I suppose I could stay there until I befriend Sweetie or somepony to stay with perhaps. Now I just need the right time to do it." She treated herself to another glass of wine and lay on her chaise lounge with her favourite romance novel and relaxed into the the candlelight.

Rarity woke up with a jump she must've nodded off. The storm sounded like it was moving away she yawned and saw the time. "Ugh! It's almost two! I need to move Rumble to the guest room." She stood up yawning stretching out her back as she made a beeline for the stairs. The Carousel Boutique was silent, it made her think of Opal and how she must be enjoying herself on her excursion with Fluttershy at the animal retreat. The stairs creaked under her hooves snapping her from her thoughts. She cast a silent spell on her hooves and crept upstairs to Sweetie Belles room. She found the door ajar and peaked inside, they were fast asleep head to hoof on top of Sweetie's bed with various papers and pens sprawled around full of project ideas. Rarity decided to just leave them both as they were. "Poor things they're all worn out." She was almost out the door when she gasped upon seeing Rumbles thick member flopped out on the duvet inches away from Sweetie's face she felt herself blush and she felt her nethers stir at the sight. "Ohh my Sweetie, you're missing quite the treat." She quietly said to herself as she used her magic to pull a throw from Sweetie's lounging chair and was about to lay it over them before taking another look at the sleeping phallus. Rarity's eyes narrowed at the naughty thought fleeting through her mind making her grin.
She daringly took his member in her magic and manouvered him closer to Sweetie Belle's face. She felt her heat building between her hind legs at being so naughty as she licked her lips wanting to taste the colt in her maw. "I hope you wake before he does Sweetie darling." Blowing them a kiss before leaving the room, she hurried to her own bedroom needing to finish what she had started in the bath earler that evening.
The soft ambience of the room embraced her as the air of the room hung heavy with anticiption, Rarity lept onto her queen size bed instantly began pleasuring herself. Laying back on her satin sheets splaying her hind legs out feeling the cool air lap at the wetness of her burning plot. "Now then, where was I.....Ahhh yes!" Closing her eyes as her hoof headed for her waiting slit whilst the other went for her her crotchtits sending waves of pleasure cascading through her body. Rarity's horn glowed as she stimulated her swollen clit with her magic, her senses lit up with absolute pleasure. Her motions became more deliberate, more focused as she sought out the perfect rhythm.
Her mind ran wild with naughty and filthy thoughts with her stallion's phallus in her minds eye soon turning in to that of Rumbles large member and thinking of it just laying out unsheathed just inches from her little sisters face like that. Well she couldn't deny feeling a little jealous that it wasn't her face it was next to. The thought quickly making her teats tingle as her hoof slickened in her juices. She was wetter than the storm outside the intimate feeling making her bite down on her lip panting heavily as her orgasm drew ever nearer with the aid of the flashing fantasies through her lust filled mind. She began panting harder as deep down in her belly tingled and knotted making her hind legs tense up as she reached her pique spraying marecum all over her quilt whilst biting down on her hoof stifling her moans as the waves of passion crashed over her quivering body leaving only the echoes of her pleasure with the gentle caress of her touch. Rarity lay back on her now sex soaked satin sheets, her body bathed in the warm afterglow now filled with a sense of contentment and fulfillment enveloping her.
