Rarity gently nudged the soundly sleeping filly next to her, hoping to rouse her from her slumber quietly. She let out a sigh when the filly stayed deeply asleep and she turned her gaze to the window trying to guess what time it might be. The pale light of morning poured in through sheer curtains, slanting across the room and lightly illuminating the peaceful white face of Sweetie Belle.

She decided to give her sister a final rousing shake, smiling as she finally began to stir. The mare wrapped her arm tightly around her little sister and pulled her small body closer, whispering into her ear, "It's time to get up and get ready for school Sweetie."

Sweetie let out a groggy whine and shook her head. "No, I don't wanna get up yet, it's warm here."

Pulling Sweetie into her lap, Rarity leaned into her from behind and began kissing and licking her ear, letting out soft breaths from time to time. "Well, maybe a little more time in bed won't hurt." She practically purred the words as she ran her tongue down the inside of the filly's ear.

The little white unicorn shuddered and pressed her ear into Rarity's soft tongue.

"Wow..." she whispered into the air as the mare she loved continued sending tingles through her entire body.

The older mare let her hoof trail down her sister's short body, brushing over her stomach and slipping into the now familiar groove between her thighs.

Sweetie parted her legs fully as she felt her sister's hoof prodding them, allowing the hoof to slip snugly between the pair where Rarity was able to reach the small nub she had been looking for. The older unicorn pressed down on the hard little ball and began rubbing it in small, tight circles picking up speed as she went. Sweetie bit her lip and let out a quite mewl of pleasure, her cheeks instantly turning a deep red.

The filly pressed herself into her sister's hoof, loving the pressure it added to her tiny clit. She let out a breathy moan and leaned her head against Rarity's side, pressing herself close to her while as she sent waves of pleasure pulsing through her body.

Rarity illuminated her horn in an aura of light blue magic and allowed a thin stream of it to coil out, slowly snaking it down her sister's soft white thigh until it reached the moist pink slit at the base. Carefully, she slid the magic up and down her sister's slit, all the while rubbing away with her hoof as her little sister's moans grew louder. Finally she pressed the magic against Sweetie's sopping hole and gave it a light push, watching as all of the magic slipped away inside the filly, adding pressure to the overly sensitive spot inside of her.

Sweetie Belle arched her back into her sister and let out a loud, high pitched moan. Her breath became a bit uneven as she took in the unfamiliar, but not at all unpleasant sensation inside of her. With one last stroke of Rarity's firm hoof she threw back her head, loud huffs and moans slipping through her lips, and her entire body shaking under the intense pleasure coming through her in waves as she climaxed around the warm magic filling her.

"Well that was fast." Rarity chuckled and let her magic disperse, sitting up as she did. "Oh well, it's probably for the best, you're going to be late for school if you don't hurry and get moving."

"Yeah yeah, I'm going now. I can brush my mane on the way." Sweetie pulled herself to her slightly wobbly hooves and headed for the bedroom door, glancing back over her shoulder as she went. "I'll see you later, Sis."

"So?" Sweetie prompted as she took her seat beside her friend on the swing set. "How did it go? Did you guys do it?"

Apple Bloom kept her eyes fixed on her small yellow hooves as her swing swayed slowly back and forth, her pink tail dragging in the dirt along with it. "I don't wanna talk about it..."

Sweetie looked at the other filly with wide concerned eyes. "What's the matter? AJ didn't hurt you, did she?"

"Of course not!"

'Well then what's got you so upset? I mean, if something bad happened you could tell me." Sweetie placed a reassuring hoof on Apple Bloom's shoulder.

Apple Bloom shrugged the hoof off and jumped off the swing, angrily turning around to face her friend. "Nothing happened okay? Nothing happened because my sister doesn't love me!"

With that the earth pony turned tail and fled back into the school building, leaving Sweetie dumbstruck on the swings.

***

Sweetie Belle trotted solemnly though the door of the Carousel Boutique, pushing the door shut with one back hoof as she passed it.

Rarity glanced up from the design she was sketching as she heard the bell ring. "Is everything alright Sweetie?"

The little unicorn looked up at the sound of her sister's voice, a smile crossing her face when she saw her pretty sister with her red work glasses resting neatly on her nose. "Everything's fine now that I'm home, I missed you."

"Oh Sweetie, that's so... sweet. I missed you too dear." The mare giggled and adjusted her glasses, turning her face up to hide her blush.

"Today at school sucked, we had to take a really long math test, and I didn't sleep very much last night so it was hard to focus."

"Oh Sweetie I'm sorry, I didn't mean to keep you up so late." Rarity frowned guiltily and leaned back in her chair, staring sadly down at her sister.

"It's okay, I didn't say I had any problem with being up last night. I just kind of want to take a nap before I do my homework today." She grinned widely and looked up at her sister with pleading eyes.

"Oh alright, but only this once."

"Yes!" The filly skipped happily into her sister's room, hopping up onto the bed and making herself comfortable.

Rarity trotted in behind her sister more calmly and looked at Sweetie's soft white body stretched out across the mattress. She bit her lip and put on a coy smile. "You know Sweetie, I never did get off this morning."

Sweetie looked up at her sister with surprised eyes and smiled shyly. "So you want me to get you off?"

"Only if you're up for it, are you sure you're not too tired?"

Sweetie shook her head and lit up her horn, performing her new favorite spell with much more ease than her last use of it. She licked her lips and ran a hoof down her long erect member, examining her fine craftsmanship before turning her gaze to her sister. "Fine then. I guess if that's really what you want."

She giggled slightly as she waited for her older sister to lay down, crawling up to her when she was comfortably positioned against the pillows. She pushed Rarity's legs up, pressing her knees to her face, just the way she had seen a stallion do in her sister's copy of Llama Sutra she looked over last night. Slowly, she ran her member up down her sister's already wet slit. "Is this how you want it?"

Rarity fidgeted slightly and pushed her hips down against the prodding penis, her bottom lip sticking out in a disappointed pout when she couldn't make it pop in. "Oh come now Sweetie, no pony likes a tease. If you want to do me, then do me."

Sweetie Belle put on hoof under either side of her sister's lower back and pulled up on her, bringing her plot closer to the erect penis the filly had just conjured. The filly rubbed the member up and down her sister's slit, more forcefully this time, pausing every so often to push lightly against her soaking wet opening.

Rarity let out a dissatisfied whine as she was once again denied the penetration she was craving. "Please don't make me wait any longer Sweetie, I need to feel it."

The mare blushed and looked pleadingly up at the filly mounting her. "Please?"

Sweetie Belle staggered and shook her head slightly, her cheeks flooding with color as she was caught off guard by her sister begging her. "Wh- I... Okay."

She leaned back slightly and then pushed forward hard with her hips, accidently slipping her pre-cum soaked member into her sister's unsuspecting asshole with a loud pop.

"Oooch!" Rarity stiffened her body as pain rushed through her.

"I'm sorry, I'm sorry!" Sweetie stared down at her sister's pained expression with tear filled eyes and backed up slowly, trying to pull herself out as painlessly as possible.

"No stop!" Rarity grabbed onto the filly as she tried to move, holding her tight in place. "J-just don't move."

The mare let out a few deep breaths as she lay under her sister, her muscles relaxing as she calmed down.

Sweetie held herself as still as she could, concentrating on not hurting her big sister anymore. "Are you okay Rarity?"

"Yeah I'm fine, it actually feels kind of nice. Do you think you can move?"

"Yeah I think so." Sweetie gave a light, uncertain pump of her hips, slipping all the way inside of her sister.

Rarity let out a light moan at the thrust, encouraging Sweetie Belle to continue. Slowly she began swaying her hips back and forth, sliding in and out of her sister's unusually tight hole.

Her thrusts grew smoother and more energetic as her sister's muscles relaxed around her, allowing her member to glide back and forth with ease.

For a moment, Rarity thought of asking her sister to stop and switch holes, but the pressure in her rear was too pleasure inducing to even consider actually stopping. Still, she couldn't ignore the throbbing emptiness of her dripping hole and she knew something had to be done about it.

"Say Sweetie, do you think you might be able to grow a second one of those, for my other hole?"

Sweetie quirked an eyebrow and stopped pumping herself into her sister's ass. "Another one? Well, I can try."

The filly illuminated her horn and focused her magic, biting her lip in concentration. Her face began turning in red with the effort. Rarity was beginning to wonder if it would prove to be too much for the filly when Sweetie began clapping excitedly, staring down at a second erect member protruded directly above her current one. "I can't believe I did it! It looks kind of funny so high up but still, I did it!"

She repositioned herself slightly, pressing down on the free shaft so it lined up with her sister's hole. Slowly she pressed forward, watching gleefully as her sister squeezed around the head of the top penis before it finally popped into her tight warmth.

Rarity bit down lightly on her tongue and closed her eyes. "Slow down, it's so tight. Just push it all the way in, slow and steady. I want you to fill me up."

She pulled her sister down and kissed her, holding her in a tight hug while she pushed down on her flank with her back hoof.

Sweetie shuddered from the sensations and pushed slowly into her sister, feeling more hot with each inch that slipped in. "J-jeez Rarity, it's sooo tight."

She grabbed her older sister's hips and thrust forward, ramming the entire length of her members into her sister. She tilted her head back and let out a loud moan, her eyes rolling into the back of her head. "Sweet Celestia, that feels incredible!"

Rarity arched her back and wiggled her hips, rubbing herself against Sweetie Belle's pelvis. She shivered and pulled her sister into a deep, tongue heavy kiss as she bounced her flank up and down, letting the shafts slide in and out of her body.

Sweetie pushed the mare's legs up higher and slammed into her as hard as she could. The filly let out a loud moan as her sister squeezed down tightly on both of her penises, her muscles convulsing in a much needed orgasm.

"Oh my gosh Rarity, I don't think I can hold it anymore." The words hardly left her mouth when her entire body shook with an intense pleasure, sending longs white streams into both of her sister's holes.

Both unicorn's breath came out hot and shallow as they lay together in their post orgasmic high, a mist of happiness hovering over each of them.

Rarity gently nudged Sweetie Belle off of her, hardly noticing the trail of cum that dribbled out when the filly moved. She lay her little sister down on the bed next to her, wrapping her arms tightly around her.

"So how about that nap we talked about?" The two sister's shared a lighthearted and drowsy giggle as they cuddled, sinking quickly into a peaceful sleep.

Author's Note

For all of you wanting to know what happened between AJ and Apple Bloom, I promise I didn't forget, that part is just far too important to be a tiny bit of one chapter. I will however be writing an entire fic for it, and that will be posted shortly so keep an eye out for it if you're interested.
