Sisters Share their Toys

Sweetie Belle wasn't supposed to be in Rarity's room, which is what made it so fun.

Rarity was out doing a fashion show thing, and she wasn’t supposed to be back for a few hours. Still, if she came back home unexpectedly because she forgot something… Sweetie Belle’s ears stayed up, listening for the front door. Every time she thought she heard something, though, it was just in her head. Or the rush of her heartbeat in her ears.

Ba-dump, ba-dump.

Rarity always lost it whenever Sweetie Belle was in her room. She got really twitchy, and she did that panicked shouting where her voice cracked, which meant she had to be hiding something in here that she was embarrassed about.

Hard cider? Nah, that was more Rainbow Dash’s thing. Cigarettes? Maybe. Rarity definitely wouldn’t want to be caught with those…

Sweetie Belle checked under the bed, and just found giant hatboxes. Back of the wardrobe? Nothing. Not even a cool false back or anything.

She was deep into it now. It was impossible to say she was doing anything but snooping if she got caught. She listened for the front door…

Ba-dump, ba-dump.

She giggled, more to ease the tension than anything else.

She checked Rarity’s bedside drawer, and the giggles caught in her throat like a hairball. On top of a battered romance paperback. There was a smooth purple rope, like what you’d tie expensive curtains up with, but Sweetie knew these were absolutely not meant for curtains. Her sister liked to tie ponies up!

Or maybe get tied up?

No, definitely tie other ponies up. Sweetie didn’t know why she was so confident about that one, but it was definitely more fun to think about it that way around.

Maybe Rarity would be mad enough to tie her up with it if she caught her.

Ba-dump, ba-dump, ba-dump.

Sweetie put the rope back in the drawer, but it pushed against something. It was like a big round arrowhead, with a purple crystal base. Next to it, a lavender smelling squirt bottle.

Definitely, definitely becoming super obvious why Rarity didn’t want her going through her drawers.

Had Rarity ever worn this in front of her, and she hadn’t noticed? How would she notice?

She was about to slide the drawer closed, but she looked at the paperback again. It had to be… that kind of book, right? If it was with this other stuff?

Memorizing the way everything was before she touched it, she slid the book out and checked the bookmark. What was her sister thinking about when she used that stuff?

Twinkleshine’s bodice ripped under her magic. It was with some amusement that Sugarstar thought she’d have to sew her Lady’s clothing back together later.

Her Lady’s legs spread for her, and it was with a calm and inviting tone that she said to Sugarstar; “Well? Are you satisfied with only looking?”

Sugarstar was not. She-

Sweetie Belle slammed the book shut on the bookmark and put it back where she found it.

This is what Rarity read? She thought she only liked... well. Jerks, from past experience.

Maybe that’s why she was reading about girls...?

Rarity would be so mad if she caught her right now.

Badump-badump-badump-badump.

There was one last place to check. Sweetie moved to Rarity’s dresser. The bottom drawer had all kinds of lingerie in it that Sweetie had never seen her sister wear. Some purple silk, some black lace, some long black stockings…

But the real prize was behind it. A real toy, as long as her hoof to her elbow and about half as thick. She sniffed it. Over the top of the latex and rubber smells was… her sister.

Sweetie imagined Rarity trying on the different lingerie, sliding down the toy. Smiling, eyes closed…

She leaned forward to lick the toy, before she could even think why. She blushed, wondering why the heck she did that, wondering what Rarity would do if she caught her now…

Badump-badump-badump-badump-

She was really curious though. She was way too embarrassed to buy her own toy, and she was… really worked up after reading that book. How did it feel? What would it be like?

Better than the handle of her hair brush, probably.

There was no way Rarity would ever know she borrowed it, right? And their parents had always told her to share her toys. They probably didn’t mean this, but…

She licked the toy again, more confidently. Trying to work out what it tasted like. She wondered If she could even fit it in her mouth.

She covered her teeth with her lips, like Apple Bloom told her about, and let her tongue guide the toy into her mouth, then kept sliding it in. A hoof slipped between her legs as she pushed it all the way to the back of her throat, and she gagged on it. She pushed past though, deeper, squeaking as she got it past that ticklish spot in her throat. Moaning as her forced-shut eyes flooded with tears.

In her mind, it was Rarity teaching her how to ‘perform fellatio’, pushing her head down on a stallion she approved of. She didn’t think about the stallion as much, her hoof moving faster as she thought of her sister’s careful instruction. Her cool tone, the way she would know exactly what to do… how a lady should. With some pride, she wondered if Rarity could ever take this much of it.

Then she wondered if Rarity had ever taken it inside her this deep, and groaned, her hoof moving faster. Then she thought about how deep inside her Rarity had taken this… and realizing how much of it she had in her mouth. Everything went white, her eyes opened in what looked like panic, her back going stiff and her legs clenching hard as she came, coughing up the toy.

It wasn’t a big one, or at least, not satisfying enough. It was like when eating snacks before dinner just made you hungrier.

Emptier.

Sweetie held the toy to the floor, and without a pause for thought, slid herself down it. She squeaked when it filled her, but wiggled her hips until she could get every last bit of it in.

Hummed, letting herself feel satisfied.

The physical stimulation wasn’t enough. She kept her eyes closed before she thought too hard about it being a rubber cock inside her, and feeling silly about it. She tried to hold the idea of a real stallion in her head, but it was like trying to hold cobwebs together. She grit her teeth, moving up and down very slightly, just enough to stop from getting too sore.

She thought of her sister behind her, guiding her onto the stallion, and squeaked again as her knees gave out a little. That did something. Whispering in her ear all the right ways to please a stallion, just how special she was…

She hadn’t listened for her sister coming home for ages! What if Rarity caught her like this?

Badumpbadumpbadump-

It wasn’t fear making her feel her heartbeat in her ears now. Had it ever been, though?

Her mind played the fantasy back to her, but the stallion was gone now. It was just her sister, guiding the toy into her. Cooing into her ear about what a beautiful girl Sweetie Belle was, how nice it was to have a sister that liked to share her toys…

She thought about Rarity using this, and slammed the toy to the hilt, trembling against the floor with as much of it inside her as she could take. Her breath came out in ragged pants. She didn’t know why she couldn’t keep a boy in her mind, but the thought of this being inside her sister did so much. She tried to think of something else, anything else.

She was close again, but it wasn’t enough just yet. None of her fantasies could stick. Her hips took a steady backwards and forwards rhythm as she tried to move it while keeping as much of it inside her as possible.

She thought of Rarity pulling the back of her head between her thighs, holding her muzzle there while fucking her with the toy. She bit the inside of her cheek, trying to remember how the toy had tasted, but it wasn’t enough. She had to know what the real thing tasted like.

Her big sister stroked her mane in her fantasies. She leaned forward and whispered into her ear, “You’re a very fast learner, aren’t you, Sweetie? Just a little more and you might make me cum.”

Sweetie screamed out, but it all caught in her throat. She thrashed against the toy, open mouthed, as she came harder than she ever had before in her whole life.

She slid forward, groaning as her now too-tight muscles let go of the toy and squeezed against nothing. A short gasp as it left her completely. She looked back at it, and it was… well, she’d messed it up, that was for sure. It was covered in… her.

She grabbed some of the tissues Rarity kept by her bedside and wiped it down as best she could, though she was a bit lust-drunk and trying really hard not to think about what she’d been thinking about. She hid the toy back where she found it as best as she could.

Rarity sighed. She didn’t know how she knew so easily, but Sweetie Belle had been snooping in her room. Sweetie had been careful, but she hadn’t put everything back the exact same way, and it set the alarm bells off in her head without quite knowing what she’d been incautious about.

Still, in a way she was relieved. It meant that Sweetie didn’t know how not to get caught, hadn’t already been doing it and getting away with it. Rarity was always a bit anxious about the idea.

She went through the major concerns. No missing clothes she could note. Her stress chocolate remained uneaten. Her bottle of emergency wine behind the headboard, untampered with.

Her bedside table… rifled through. To be expected, but would Sweetie even know what those things were for?

Of course Sweetie would. Good grief, she certainly had at that age.

Stars above help Sweetie if she had the same libido Rarity had at that age, as well.

She checked. Rarity had definitely found at least one of her toys. It had moved. She took it out to inspect it and-

Oh dear.

It was still a little slick with her sister.

She’d tried to wipe it down, but must have been more panicked than thorough. Now she was going to have to clean this, or the next time she used it...

Rarity stared at the toy, and pressed it to the ground curiously.

“Well, now,” she said to it dryly, “Aren’t you a dirty little thing. Seeing my sister behind my back?”

The toy didn’t reply, obviously too ashamed.

“Lucky for you, I am quite generous. Sharing is not an issue.”

She stared the toy down. She should boil it, really. But the thought of Sweetie Belle using it as well made it feel quite... intimate. Special.

She lined herself up with the toy and bit her bottom lip.

“You’re going to have to tell me which of us does better. My sister certainly has her charms. She might even be prettier than me, on a good day. But-” she sank down deep onto the toy and let out a low and throaty groan. “There is something to be said for experience.”

She rose slowly and let herself sink back down to it, and laughed to herself.

“I do love her quite dearly. You better have treated her right.”

She got into a better rhythm, wondering how Sweetie took it. She reached down to the base with her hoof, eyes widening. Really now? That far?

Rarity sank down, wondering if this was how Sweetie had felt. Wondering if Sweetie thought about her when she used it, in the same way.

She thought about hugging her sister from behind as she bounced up and down on a stallion - no, just a toy, it was just them she decided, less complicated - guiding her, giving her encouragement...

Mmmmm.

There was a wooden creak of the floorboards. Rarity stopped for a moment, her heart caught
in her chest. Sweetie was still here, wasn’t she? She was spending the night. She’d definitely heard.

She tried to look at the door without looking like she was looking. It was definitely cracked open. She hadn’t closed it behind her... but this, she realized, was Sweetie being bad at not getting caught.

So what did she do about it?

Rarity slid back down on the toy with a private smile, then stood up, pulling it out.

“Let’s take this to the bed, shall we?”

She settled herself back on the bed, lying on her back, closing her eyes. She teased the toy slowly against her entrance, letting in just the tip at a time. Her magic found her clit and-

Ah!

Definitely found the right spot.

She’d positioned herself so that anybody looking in from the doorway would get quite the view. So they should. Now she was putting on a performance.

More than anything else, Rarity liked attention. She liked the idea of being watched.

Watch this, Sweetie, Rarity thought as she slowly took the toy, not daring to check the doorway in case she scared her off. This is how a lady fucks herself properly.

She didn’t keep her voice down, didn’t keep quiet. She made a very unladylike grunt as she took the toy deep, forcing all the air out of her lungs, and drunkenly laughed as she took the air back in. Drunk was the keyword here, all sense had left her.

She thrashed about, gripping the silk sheets as her magic rammed the toy into her. She thrashed her hips up into it and off the bed.

The whole time she was thinking of her sister watching her, how she must look. About putting on a proper performance, an educational experience.

Most of all, she wanted to make Sweetie jealous. She’d shared her toys, sure, but she needed to know that big sister played better.

She felt close, right on the edge. She desperately flicked her clit and sucked down hard on her lower lip, going quiet. As she did, she could hear Sweetie’s squeaks for the first time. She’d watched the whole thing.

She came harder than she had in a very long time. There was no cry, no scream, her throat entirely locked up as her entire body jerked up, up off the bed. She lost control, spraying the toy and soaking right through her sheets.

She tried to laugh, but the orgasm was still rolling through her. It came out forced through her clenched-tight jaw, manic and satisfied.

When was the last time she’d squirted? Months? Years?

She flopped, boneless and noodley, and panted until she caught her breath back, still drunk and dizzy and giggly.

“That,” she grinned, “is how it’s done.”

She floated a bathrobe over to herself and pulled it tight, and went to inspect the doorway.

A distinct wet patch on the floor. Sweetie had apparently been watching with more than just curiosity.

Rarity stared at it. Her sister hadn’t been learning from her, she’d been thinking of her. Enjoying the show in a way Rarity might not have intended.

Or, a hungry voice inside her whisper, perhaps exactly as intended?

So again: How did she feel about that?

The first thing had been to wake up early enough to make breakfast. Already a priority, — Sweetie never did learn to cook.

The second thing was trying to manage making pancakes with a plug filling her, pushing her tail up in a subtle-but-not-too-subtle way, and making her feel wholly indecent. This, she thought, she’d done with aplomb.

It was distracting, but fun. Like a self inflicted itch. Something small, just enough to keep your attention on it, but not enough... well, frankly, not enough.

She knew Sweetie had found this last night. And she suspected she knew what it was.

So how effectively could she keep up the lie that she hadn’t gone through her room to find out?

That was the fun of it. Though Rarity was the one who was acting... indecent, to admit to noticing it meant Sweetie had to incriminate herself.

But how well could Sweetie hold up pretending she didn’t notice?

At least, that was the thought she’d had when she’d come up with the plan.

Sweetie stumbled into the kitchen, sliding up to the breakfast table while rubbing the sleep out of her eyes. “Smells good.”

“Oh, Sweetie, I’m so glad you’re up. Please...” Rarity smiled at her over her shoulder. “Come and get some while it’s hot.”

She frowned in her own head. Really? Laying it on so thick?

She realized she’d been enjoying the plug a little too much. She hadn’t worn it outside the bedroom before, as much as she’d fantasized about wearing it under a dress, the risk of getting caught had never quite been worth trying it.

She hadn’t realized just how much an itch can build up when you’re not allowed to scratch it.

And now Sweetie was staring at her, open mouthed and blushing bright red. And Rarity couldn’t help herself from smiling back.

Sweetie squeaked.

Now, here was the thought. Sweetie Belle knew. And Rarity knew that she knew.

So what did they do about it now?

It had been with a much clearer head that Rarity had planned on teasing her sister, but hadn’t planned on being so affected when she got to this point. She had, as Rainbow Dash would put it, played herself. Now she was thinking of ways she couldn’t push this a little further. The same little voice that whispered in your ear, when you look over the edge of the cliff… jump.

“Tell me, Sweetie. When you put it upon yourself to share my toys —” She paused to savour just how red Sweetie’s face turned; she’d closed her eyes and looked like she was trying to wish herself out of existence. “Was it because you wanted one of your own? Or is it because it was mine?”

Sweetie squeaked again, and quietly hid under the table. Rarity blinked. She… hadn’t expected that much of a reaction.

That was… quite a revelation. It more or less confirmed that it wasn’t jealousy, but maybe even... a crush?

The little voice that shouted jump made her want to know more.

“Rea-lly?” Rarity hummed, but Sweetie kept hiding under the table. “My, my. Aren’t we learning some interesting things this morning?” Rarity paused for dramatic emphasis, and not at all because she was nervous. Sisterly teasing, all this was. “So, you thought about me when you were fucking yourself with it, then?”

Sweetie Belle jumped at the question, banging her head against the bottom of the kitchen table. “Ow.”

“Oh, Sweetie, you poor thing,” Rarity moved towards her, but paused. Sweetie had just bumped her head. It was just to reassure her, wasn’t it?

Sweetie, meanwhile, was still hiding under the table, thinking about how secret agents got cool cyanide capsules to bite down on in situations like this. Which was bad enough, but now her head hurt too.

Her sister pulled her out from under the table to look at her, and squished her in a big hug. It was really nice, and almost innocent… but Sweetie couldn’t stop thinking about what Rarity was hiding under her tail the whole time.

“Poor thing. Let Rarity kiss it better.” Sweetie went stone stiff. “Where did you bump it?”

“It’s fine, really.”

Rarity kissed her on the top of the head. “There, better?”

Sweetie hesitated. That was pretty nice. “Ah, yeah, actually.”

“Mm. I thought so.” Rarity kissed her again. “Mwah.” Then again, right at the base of her horn.

Sweetie went stiff. “T-there.”

Rarity’s voice was a mix of concerned and teasing. “There?” She kissed again. “That’s very sensitive, isn’t it? That must have hurt a lot.”

“Y-yeah,” Sweetie gulped, “It did.”

“Mwah.” Rarity kissed up her horn’s length, and Sweetie forgot how to breathe. Rarity wrapped her lips around the tip, kissed, then slid down its length, her tongue circling down the grooves and sending static sparks crackling down Sweetie’s spine.

“There,” Rarity breathed, leaning back. A thin bead of saliva hung between her mouth and Sweetie’s horn, which she wiped with a handkerchief. “Feeling better?”

Sweetie took a shaking breath in, too stunned to talk. She managed a wobbly nod, at least.

“Good.” She kissed Sweetie on the cheek. “Don’t you ever doubt just how much I love my beautiful little sister.” Rarity leaned back and smiled at her, and Sweetie’s head filled with a roar of white noise and feedback loops. There was just too much, and she felt too much of it, to handle this. Rarity giggled behind a hoof.

Sweetie wondered why, and as her thoughts swam back up from the warm and fuzzy deep space it had gone to, a realization bobbed up like the little plastic triangle in the magic eight ball.

Rarity knows I watched her last night, and liked that. That’s why she’s doing this.

But Rarity probably didn’t know that Sweetie knew that, which meant... she didn’t know what it meant, yet, she was still tingling too much.

Wait.

It did mean something important.

It meant that her big sister was at least curious too. Probably more than she was willing to admit.

So saying, “Rarity, can I bury my muzzle between your legs while you fuck me with your magic,” would probably end this right now.

But she didn’t have to say that.

“Ah, Rarity? I’m sorry about going through your room.” That put her on the backfoot, and super surprised her, which was only fair after the horn thing. “But I was really curious about your, uh... thing.” She made a long gesture with her hooves.

“Yes, that thing. I know what you mean.”

“Um... I was hoping...” This wasn’t part of an act, or devious plan. Sweetie stammered and blushed. “Could you show me what I’m doing wrong, with it?”

Rarity stared at her, and Sweetie wondered if she didn’t push too far. Was Rarity really just going to forget they both knew she had a... something in?

Her sister kissed her on the cheek. “Very well. But we really must get you your own, eventually.”

Eventually. Not ‘no’, and not even ‘soon’. Rarity liked sharing just as much, she just didn’t want to admit it.

Sweetie smiled to herself as she hugged Rarity tight. “Thanks Rarity. This is really embarrassing, and there’s nobody else I can really ask stuff like this...”

“Certainly,” Rarity forced out. “What else are big sisters for?”

They were in her bedroom again. Rarity got the toy out and gave it to Sweetie, who positioned it on the floor in front of the bed. She had permission to be here, this time.

Certainly, Sweetie had already watched her little performance last night, when Rarity had thought it was just a passing curiosity. Did Sweetie know that she had known? Apparently not.

Which left her asking what Sweetie hoped to learn that she hadn’t already seen?

They stared at the toy, standing at attention in front of Rarity, and then at each other for a moment.

“Stage fright?” Rarity tried her best to smile reassuringly. She wondered if she shouldn’t, as Rainbow would say, chicken out, but she found she didn’t want to. If Sweetie was open to sharing this part of herself, then it wasn’t her place to deny her that.

How hard she had to keep her knees pressed together now, though, was another thing.

Sweetie stared at it, biting her lip. “Which way is better? Is there a better... angle? I guess.”

“It’s a little different,” Rarity tried to keep her voice steady, “But mostly it’s how personal you want to be. Are you making love, or are you just getting rutted.”

Sweetie began stroking the toy thoughtfully. “What do you mean?”

“If you are facing away from your partner, then there’s a more... primal, bestial quality to it. It’s when you want to be taken, hard and fast. Then there’s the other way. Slow, romantic. An experience with another pony, to be savoured as much as the act itself.”

Sweetie sat down next to the toy, and scooted up to it until her legs wrapped around it. She hugged it against her stomach, like a teddy bear. “So what’s better?”

“Well it depends. It’s like... I hope you don’t understand this intimately, Sweetie, but it’s like the difference between doing shots to get drunk, and drinking a bottle of wine in a bubble bath with a good book. Both have their advocates, though it’s said that...” Rarity trailed off— watching Sweetie so innocently hugging the toy like that was distracting her.

“What do they say?”

“Ecchem.” Rarity held her knees closed, “It’s said that your experience is ruined less by cheap vodka than bad wine, as it were, if all you really want is to get sloshed.”

“Right,” Sweetie nodded. She spun the dildo on the floor so that it was facing away from Rarity, into Sweetie’s stomach.

Then, she shifted up and rested her weight on it, facing Rarity. She dragged her hips forwards and backwards against the tip of it, making breathy little gasps.

Rarity forgot how to breathe.

Then, with an evil smile, Sweetie slid down the toy, making unbroken eye contact as she slid lower and lower. Rarity couldn’t look away.

She breathed, as quietly as she could, but deep enough that she felt the hammering of her heart right against her breast.

“So,” Sweetie asked innocently, just the base of the toy visible underneath her, “If it’s facing away, it means you just want to get fucked.” She wiggled for emphasis, and bit back a sharp gasp when it got more of a reaction than she was expecting. “But eye contact,” she continued in a breathier voice, “If it’s intimate?”

Rarity leaned back on the bed. She felt her knees come apart with some concern. “That would be the gist of it, yes.”

Sweetie moved slowly, up and down, forward and back. She sighed. Every time she locked eyes with her sister, she smiled sweetly, like she was just happy to be here together.

Rarity let a hoof between her legs. Too transfixed to move it yet, but getting too worked up to keep ignoring it.

She cleared her throat. “There really isn’t much more than that,” she watched, “it’s all about finding what you like.”

Sweetie licked her lips, leaning forward closer to the bed. “Finding what I like, huh?” She asked.

The hoof between Rarity’s legs twitched.

Sweetie took the toy to the base again and, after a squeal and a little squirming to get it fitting comfortably, sat comfortably like that. “What if I like girls?”

Rarity didn’t even notice that her hoof had started to lazily move up and down, making lazy rings. “What do you mean, ‘what if I like girls’?”

Sweetie gestured down. “This is easy. I think I’ve already figured this out for myself.” She looked down at herself and giggled at the slight bulge in her stomach, running her hoof along it. “But girls are complicated.”

Rarity couldn’t stop herself staring at just how full her sister was. “I haven’t had much experience with them, myself.”

Sweetie lifted the toy’s suction pad off the ground with a squelchy pop, and scooted forwards towards the bed holding it inside her, resting her head on Rarity’s knee. “Could I practice on you, and you tell me if I’m doing a good job or not?”

“Sweetie! That would be highly inappropriate.”

Sweetie Belle meaningfully looked down between Rarity’s legs, and Rarity’s eyes followed. She’d been playing with herself for a little while now, and her hoof was soaked. Sweetie raised an eyebrow at her.

“I’m just worked up, that’s all.” Rarity grimaced.

Sweetie let the soaked toy slide out of her, finally. Rarity couldn’t help but notice how shiny, slick and soaked it was, as much as she tried.

Sweetie jumped up on the bed next to her. “Rarity,” she whined, “Don’t you think I’m pretty?”

“You’re the most beautiful pony in the world who isn’t moi.”

Sweetie grinned. Then she disappeared behind Rarity, and she was too nervous to turn around. “And wasn’t it really hot watching me just now?”

Rarity said nothing, because it was the only safe thing to do, and Sweetie couldn’t see how much she was blushing right now. Then her sister wrapped her in a big squeezing hug from behind, and kissed her cheek.

“Raaaarityyyy,” Sweetie pretend-whined in her ear, because Rarity was a great sister who had taught her so well, “Kiss me.”

“So you can practice kissing?”

“No, because I really want to make out with you.”

Rarity kissed her before she could think twice about it. Sweetie opened her mouth and pressed in, and Rarity bit her bottom lip and held it until Sweetie could settle down.

Sweetie frowned as she leaned back, and Rarity giggled. “I’m not your first, am I?”

“Shut up!” Sweetie’s voice cracked.

Rarity spun around and pinned Sweetie beneath her to the bed. All that false innocence and coy seduction melted in a moment, looking up at her with wide eyes and blushing. “What did you say?”

“Sorry.”

“Mm,” Rarity hummed, kissing Sweetie’s forehead. “You’ve been very aggressive, haven’t you?”

“... no?” Sweetie lied.

“Mmhm,” Rarity corrected, biting the tip of her ear. Hard enough to hurt, not hard enough that it only hurt. “But we’re at the limits of your experience, aren’t we?”

Sweetie was silent, looking up at her again.

Rarity leaned down and kissed Sweetie again. This time she was gentle, receiving. Learning. Rarity opened her mouth just slightly and Sweetie reciprocated, gentle. Intimate.

She relaxed so she wasn’t hovering over Sweetie anymore, but resting against her, pressed. Their chests together, their heartbeats aligning.

Badump-badump-badump-

Rarity kissed down the side of Sweetie’s mouth, her cheek, her jaw, her throat. Sweetie’s eyes were closed and her breaths shallow. She offered no resistance, just a hormone-drunk twist of her head to expose her neck to her sister.

Rarity bit down hard enough to leave a mark. Sweetie cried out, and it wasn’t in pain. If anybody asked where she got it, she’d have to lie. She’d like lying.

The lying made this more private. More intimate.

She ran a hoof through Sweetie’s mane, then down the back of her neck, down her side between her sister and the bed, until she was at her waist. There she pulled them tight.

Sweetie groaned, resigned, waiting for what came next.

Rarity trailed kisses down her chest, her stomach. Between her legs. Sweetie had stimulated herself wonderfully, but she hadn’t cum yet.

She took a long lick, and savoured the taste. Sticky, slightly salty, not sour. A smell that pushed the thoughts out of Rarity’s head and just left her with impulse.

But the marvellous thing about Rarity’s head was that impulse without thinking was just another kind of thinking for her.

Sweetie’s clit was adorable. Stunningly perfect, in beautiful smooth lips. It was just poking out from under its hood from her arousal alone right now. It was small, which meant it was exceptionally sensitive.

Rarity brushed the hood back with her lips and suckled on the clit. Sweetie cried out, and grabbed a pillow and smushed her own face with it.

Pausing for breath, Rarity took the pillow off her face with her magic. “No, no, I want to hear you,” she corrected with a click of the tongue, “That’s my little gift to myself.”

Sweetie nodded, then let her head fall back against the bed.

With her magic, Rarity made a spiral shape, a bit like a horn with a round top. She pressed it into her sister, pressing low and deep, pressing the bottom walls down, letting her stretch.

Sweetie stopped her, suddenly. Sat up and threw herself around Rarity’s neck again, pulling her into another hungry kiss. Rarity tried to tease her back down, but this time Sweetie wasn’t going to be slowed down. She sucked at Rarity’s lips, tasting herself from the kiss, licking herself off of Rarity’s tongue.

Then she pecked kisses down Rarity, pulling her up more into the center of the bed as she did, until she was between Rarity’s legs.

She didn’t have the finesse of finding Rarity’s clit, of teasing it out and suckling it. She didn’t trail gentle kisses and playful goading of Rarity’s lips.

Sweetie was eating Rarity like she was ripe fruit, juice dribbling down her chin, desperate and touch-starved. She looked up as she did, her pupils blown out. She was high on this.

Rarity curled forward around Sweetie, gripping the back of her mane. Her legs crossed behind her neck and locked, holding her tight. Sweetie pressed in tighter and moaned.

In the moments Rarity could even open her eyes, and wasn’t seeing stars, she saw that Sweetie had a hoof working furiously between her legs. With what mindfulness she could muster, she brought the dildo, long neglected on the floor, up behind her and pressed it to her sister’s soaked pussy.

She considered how to play this. Then Sweetie paused for breath, panting hot and heavy bursts of air right against Rarity’s clit, and she shook from the weight of shivers settling in her spine.

She remembered Sweetie’s decision before. The toy twisted so it would take her from behind, but Sweetie had been careful to make eye contact with her.

Rarity cupped Sweetie’s chin for a moment and let it rest against her, looking down into her hazy eyes.

That’s when she started fucking her.

Hard.

Sweetie screamed, pressing her forehead down hard down into Rarity’s pelvis. It was almost enough.

Rarity cupped her chin again and held her head up, forcing her to look right at her again. With a smile, she whispered - Sweetie paused her screams just long enough to hear - “Would my adorable little sister like to cum for me, now, please?”

Sweetie screamed again, grabbing onto her sister’s thighs like a drowning girl holding driftwood, Rarity leaving the toy inside her hilted until the spasms finally, finally died down.

Her little sister, boneless, crawled up the length of the bed and curled into her side, hugging her as tight as she could and squeezing.

“What about you?” she just barely managed to croak out.

Rarity kissed her forehead. “I’m more of a wine-in-the-bath kind of lady.” She cupped Sweetie Belle’s cheek and pulled her in for a deep, romantic kiss.

And, as she did, she took the sister-soaked toy, and slid it into herself.

She rocked Sweetie on top of her, and pulled her even deeper into the kiss, moaning slightly. Sweetie’s tired, loving reciprocation, her cute little sighs and gasps as the aftershocks rocked through her.

Rarity didn’t move the toy more than half an inch at a time. She just thought about what she’d done with it, where it’d been.

Of the spectacular performance her sister had put on for her before.

Of fucking herself silly with it the night before while her sister secretly watched and touched herself, trying not to get caught.

Of the shy but eager tongue in her mouth right now, that tasted like-

That did it.

They squeezed each other tight as Rarity silently had the most intense orgasm of her entire life, echoing through her and redoubling every time Sweetie’s weight shifted on top of her.

“I love you, Rarity.” Sweetie sighed in her ear as Rarity began sliding the now-too-big toy out of her.

A choking noise as Rarity came again.

The toy drifted back to the dresser. She’d have to clean it properly before using it next time... right now they were both half asleep in each other’s tangled limbs, letting the post-sex giggliness carry them the rest of the way.

“I love you too, Sweetie Belle,” Rarity kissed her gently, on the lips, “very much.”

Sweetie groaned. “We’re not dating though, right?”

Rarity shook her head. “No, I should think not.”

“But that was really good, right?”

Rarity nodded.

Sweetie yawned, nuzzling deeper into Rarity’s side. “Want to tie me up some time and use me like a toy for a few hours?”

“I always wanted a doll as pretty as you are.” Rarity kissed her horn again.

Sweetie sighed happily, and fell asleep against her like that.

Rarity listened to her gentle breathing for a minute, and then fell asleep to the beating of her heart.
