Sweetie Belle ran alongside Apple Bloom, heading toward Ponyville.

“I hope she didn't do anything dangerous.” Sweetie Belle said as they reached the town square.

Apple Bloom nodded and slowed to a trot. “Ah hope so too. What say Ya head to Rarity's an' see if ya can't borrow some stuff. Ah'll go check the Library.”

Sweetie Belle nodded nervously. “Um, okay?”

“Meet back at the clubhouse in, two hours?” Apple Bloom rushed off toward Twilight's Library.

Sweetie Belle sighed and headed for her sister's home / Boutique. As she arrived, she carefully peaked in through the window. She spotted her sister outfitting that funny new Unicorn in town... Peach Snaps?

She smiled and slipped around the back, hoping to enter through the back door, but she found it was locked.

“Aww.” Sweetie whined a little. “Guess I have no choice...” She checked to make sure she had her saddlebags. “Perfect.” She smiled sweetly as she headed back for the front. A moment later, the young Unicorn entered the shop.

“Oh hello Sweetie Belle.” Rarity smiled. “I'm a little too busy right now to play.”

“Oh, I'm not here to play. I, um... Yea, I kinda forgot something of mine last time I slept over. I'm just here to pick it up.”

“Whatever did you forget?”

“Um... I can't remember, but I know I forgot something.” She smiled her most innocent smile.

“Can't remember?” Rarity eyed the filly critically. “Well, if you wait I can help you look for it.”

Peach giggled. “Miss Rarity, she's you little sister. You should always give you little sister some leeway.”

“Like you and your 'little' sister?” Rarity asked, a light chuckle in her voice.

“Rainbow Dash isn't my little sister. She's a couple months older than me.” Peach replied plainly. “Though I guess she doesn't always act the older of us.” She tapped her hoof to her chin. “If you like, I can wait while you help your sister out. I'm just asking you to mend my vest.”

“And I said no. That old vest is to old, tattered and stained from travel. You deserve a new one.”

“But... It's Dragon leather. Do you know how much Peach Shine it took to get that dragon drunk enough for me to steal his cast off skin?” Peach asked.

Rarity rolled her eyes. “That's another thing. Dragon 'skin'. It's barbaric.”

“And it's lasted me ten years.” Peach replied. “Tell you what, if I can get more, you'll make me a new vest from that. Alright? I don't think silk or cotton will last me that long.”

The white Unicorn looked over the current vest. “How will you get more?”

“I'll just get another dragon really drunk.” Peach grinned. “Oh yea, and it looks like Belle has gone up to get whatever she left.”

Rarity spun and stared at the empty spot where her sister had been standing. “Oh dear... Sweetie Belle.” She whimpered a little. One one hoof, her little sister tended to require supervision at the best of times. On the other hoof, she was with a customer.

“I'll see you when I get some more leather.” Peach Schnapps donned her old vest and smiled. “Have fun.” With a green flash, the small Unicorn vanished.

“Thank you Peach...” Rarity thanked the oddly wise pony as she disappeared. Once she was gone, she rushed upstairs.
...

She had to work fast.

Sweetie Belle figured she only had a couple minutes to grab a few small items and get back to the guest room before Rarity came calling.

It wasn't hard to locate the box, as it was at the foot of Rarity's bed, in her bedroom. She opened it and looked in.

A few long, narrow things with tapered ends. A few things that looked like colt part, though these were all pretty big. Some of those things that Fluttershy used to tie Rarity up...

She grabbed three of the long, narrow things and quickly stuffed them into her bag. She closed the box and looked up, right into her sister's face.

Sweetie Belle scampered back, her eyes wide in shock. “R-Rarity?”

“Sweetie Belle...” Rarity pulled the items from her little sister's bag. She looked only a little upset, but not actually cross. “What do you think you are doing?” Her face was a little red.

“I... It was Scootaloo and Apple Bloom's idea.” She hung her head. “They told me to get something like these things of yours.”

“Sweetie Belle, is this so you can try to get your cutie marks?”

The filly nodded.

“Oh Sweetie. As far as I know it's impossible to get a cutie mark for stealing, and also impossible to get one for using items like these.” She didn't mention it was possible to bet a cutie mark for creating such items.

“So... no cutie mark at all?”

“None that I know of, to be honest.” She sighed. “What were you three planing on doing with these anyway?”

“Um... kinda what... mumble mumble.”

“Speak up please.” Rarity lifted Sweetie Belle's chin and looked into her eyes. “May you say that again so I can hear you?”

“Kinda what you and... you and Fluttershy...”

Rarity blushed brightly. “And how do you know what Fluttershy and I do?”

“I... I had to come back to get my blanket, that night Scootaloo and I were sleeping over at Apple Bloom's. I heard something and came to check, and saw the two of you.” Her face was quite red.

“And you... watched?”

Sweetie Belle hung her head and nodded.

“Oh dear... Just now much did you see?”

“I ran when you suddenly opened the window.”

Rarity sighed and hugged her little sister. “Sweetie Belle, what Fluttershy and I did, that's for grown up ponies, not for little fillies.”

“I'm not that little anymore.” She fumed.

“You still don't have your cutie mark.”

“That's why were trying this.”

Rarity frowned. “You'll do this, no matter what I say, won't you?”

Sweetie Belle nodded, just a little.

Rarity sighed. “Do you even know what to do with these?” She levitated the three vibrators.

This time Sweetie Belle shook her head.

“Then what were you going to do with them?”

“I... I don't know. Maybe Apple Bloom or Scootaloo...”

Rarity nuzzled Sweetie Belle's cheek gently. “They sent you to get these, because you told them that I had them, right?”

A nod.

“So, what's the chance that they know how these work?”

“Not good?” Sweetie Belle guessed.

“Right.” Rarity nodded. “Not knowing how to use some of these items could cause you harm, especially when you're as young as you three are.”

“I'm sorry I tried to take them. I know I shouldn't take things without asking first, but it's really embarrassing.”

Rarity sighed. “I'll tell you what. I'll show you how to use these, seeing that the three of you are so determined to try for your cutie marks. Also, seeing that they are the smallest ones I have, they shouldn't do you any harm.”

Sweetie Belle looked shocked again. “Really?”

“I know you three will do anything to get your cutie marks, and I'm confident this will not earn you them, which is the only reason why I'm going to let you experiment with them.” Rarity patted her bed. “Now, up on the bed with you, and off with your saddle bag.”

Sweetie Belle stepped back. “What?”

“You may as well be comfortable while I explain the use of these, and perhaps a couple other toys.”

Sweetie Belle nodded and used her magic to shrug off her saddlebags.

“You're using magic now?” Rarity smiled. “That's wonderful. It makes using these so much better.”

Belle nodded and climbed up onto the bed. “I've been practicing. Mom doesn't want me learning magic till I get my cutie mark, but I thought I might be like Twilight Sparkle and have magic as my special talent. I started practicing in secret.” She grinned sheepishly.

“Well, I won't tell Mother or Father, so long as you eventually tell them yourself. Now, back to the matter at hoof.” She placed the three vibrators and a a pair of the smallest 'pony parts' she had. “First, I'm certain you've seen a penis before.”

Belle blushed and nodded. “They look really funny.”

“Yes, but they can be quite fun as well.” Rarity levitated the smallest of the pony cocks. “Do you even know where this would go?”

“Um... In your pussy?”

Rarity blushed. “That is correct, but at your age, you're still a virgin.” She held up a vibrator and turned it on, creating a fine buzz. “You don't have to insert these, just rub them over your pussy.”

“Really? Does it feel good?” Belle picked up another one and turned it on. “Oh, it tickles my magic.” She blushed brighter than before and could feel her horn warming up.

Rarity giggled at her little sister's response. “Yes, it does, doesn't it?” Her own blush was quite evident.

“And you touch it here?” Belle lifted her tail and pressed it to her vagina.

“Sweetie wait...” Rarity gasped, but it was too late. The look of pleasant surprise on her little sister's face was priceless. “Oh Sweetie Belle.” She giggled.

“Oh my gosh...” Belle rolled onto her side and spread her legs. “This feels wonderful.”

What else could she do? Rarity sighed. “If you press it here...” She used a bit of her magic to guide the vibrating toy to slide a little between her moistening lips and against the filly's clit.

Belle's eyes went wide and she gasped at the sudden increased sensations. She arched and gasped even more. “So good.” She moaned.

Rarity suddenly grinned and took the second vibrator. “You can even put it here.” She pressed the tip to Belle's anus and gave a little push, penetrating an inch. She watched as Sweetie Belle cried out pleasantly.

The filly was starting to get really wet now, and the juices dripped down as she rolled onto her back. Her anus getting wet and allowing Rarity to push her toy in even deeper.

Belle rubbed her toy up and down her pussy, over her clit and between her lips. She started bucking her hips suddenly, her eyes wide and her voice crying out cutely as she came suddenly.

Rarity bit her lower lip. For some reason, watching her little sister getting off was making her wet as well. She grabbed one of her larger dildos and slowly inserted it into herself. She moaned with pleasure as she fucked herself.

Belle watched this and started to push the vibrator into her own pussy, but met resistance. “It's not going in like yours.” She cried a little.

“It might hurt if you try to put it in deeper.” Rarity explained, slowing her own playing enough so she could actually speak.

“But you can do it. I want to try it too.” She pulled out the vibrator and grabbed the smallest pony dildo. “Can you help me?”

“I don't know...”

“Please?” Belle gave her best 'cute as a hundred kittens' look.

“Oh... I know I shouldn't...” She looked at Sweetie Belle again and sighed. “Alright. I'll help you, but you'll have to bare with a little pain before it starts to feel really good.” She grasped the dildo, keeping the vibrator buried nearly all the way in Belle's ass. She pressed the tip to the tiny cunt and started massaging it in.

Belle moaned as she was penetrated to her hymen.

“Brace yourself Sweetie.” Rarity took a little breath and braced herself. She didn't like causing others pain, even if she enjoyed it a little herself. Then she pushed.

Belle's eyes shut tight and she gripped the blanket tightly with her hooves. She grimaced a little but didn't cry out. A few tears fell from her eyes, just as a few drops of blood dripped out onto the comforter.

“Are you alright Sweetie Belle?” Rarity asked, concerned.

“It... It only hurts a little.” She bit her lower lip.

Rarity smiled and started to use the dildo on her sister. She pulled out a little, then back in, a bit deeper than before. She was being careful as she 'educated' her little sister. The wet sounds the toy was making made Rarity even hornier. She started plunging her own dildo in and out again, while doing the same with her sister.

“It-it's starting to hurt... less.” Belle squirmed, lifting her butt so Rarity could push the realistic looking cock into her pussy as far as she could. “F-Faster.” She gasped cutely, her tongue hanging out of her mouth cutely and erotically.

Rarity smiled as she increased the speed to match her own. Again, Belle's hips started bucking wildly as she came a second time. She didn't stop there. Rarity pulled out the vibrator and grabbed the second small dildo and inserted it into Belle's ass.

She alternated their movements, one pulling out while the other went in, and then reversed. Rarity then did the same with herself. She hadn't tried double penetration on herself yet, but the moment she did, she almost melted. It felt wonderful to be filled up so much.

Rarity stood up and on top of Sweetie Belle, her crotch over Belle's face, and her own over Belle's crotch.

They watched each other being double fucked by the toys till Rarity finally came herself. Her pussy juices flowing out and onto Belle's face. Some got into the filly's mouth as she was gasping.

“Ahh...” Belle gasped and tasted her sister's fluids. Sweet with a hint of salty and bitter. “You-you taste good Rarity.”

Rarity smiled and brought her head down, pulling the colt cock from Belle's pussy. She wrapped her lips around the small mound and started licking deep inside.

Belle's eye's went wide. “Sis? What-what are you” She suddenly gasped as the tongue ran over her g-spot. She came instantly, granting Rarity the first taste of the filly's pussy juices.

Belle was gasping for breath now. She had cum three times already and was feeling fatigued.

Rarity sensed this and pulled the toys out from Belle's and her own holes. She lowered her dripping cunt to Belle's face. “Go ahead and lick it. It feels really good, doesn't it?”

Belle gripped Rarity's waist and almost buried her muzzle between the tight folds, her tongue lapping up at the sweet juices, tasting Rarity's own pussy and almost becoming intoxicated by it.

As Belle lavished the attention on her sister's pussy, Rarity gasped and came again so suddenly. Sweetie Belle had just discovered her sister's own g-spot and hit it perfectly. The filly was treated to a mouthful of Rarity's pussy juices.

After cumming again, Rarity collapsed next to Belle, breathing heavily. “Oh Sweetie Belle...” She glanced at the blank flank, glad that nothing had appeared because of this 'educational' session.

“Thank you Rarity.” Sweetie Belle moved so they were face to face. “I know what to do now so I won't get hurt.” She nuzzled her sister under the chin.

“Any time Sweetie Belle. Any time.” She rose and got off the bed. “We should clean up before the mess becomes difficult to deal with.”

“Of course. Let me just catch my breath.” Sweetie Belle closed her eyes for a moment, but that was all she needed before passing out.

Rarity smiled and kissed her sister's forehead. “Don't worry Sweetie Belle. I'll clean this up, and you can take a shower when you wake up.”
