Breaking the Belle

IV: Training Day

The last light of the evening sun poured in through Sweetie’s open window, illuminating her innocent face and the table at which she sat. Floating in the green warmth of her magic was a crayon, which she used to color a picture of Princess Celestia she’d drawn. It was by no means fantastic, but Sweetie was still pleased with it. Drawing was a big hobby of hers, one that she hoped to take further someday. Her attention was torn away from the page, however, by her Sister’s voice emanating from behind her.

“Come along Sweetie. Let’s watch television together.”

“But Rari! I’m coloring!”

Rarity took a step forward.

“Come and watch television with your Sister. She’s asked you once.”

Either Sweetie didn’t catch the severity of her tone, or she willfully ignored it. Either way, Rarity watched the filly not getting out of her chair. Shaking her head to herself, she strode up to Sweetie’s side, lifting her hoof to her chin, before slowly yet forcefully pulling the filly round to face her. She craned her head down, leaning in, looking the filly straight in the eyes.

“Go downstairs, before I make you.”

“Nuh-uh Rarity! I don’t wanna.”

Rarity pulled back, her face neutral.

“Very well.”

And with that, she spun on her heels and left the room, leaving the door open.

“Heh,” Sweetie thought to herself, turning back to her picture, “score one for Sweetie Belle!”

The filly practically leapt out of her skin with shock as she felt a large, leather collar constrict around her neck. She gasped, pawing at the desk, the grip cutting off some of her air.

“Too tight for you? Apologize for that attitude and I’ll loosen it.”

“S-SSohrry Rarrityyi-”

“Close enough.”

With that, Rarity loosened the collar, allowing the leather strip to slide through the metal clasp, pinning it in place at the acceptable tightness. Listening to the little mare gasp and gag as she caught her breath, Rarity took ahold of the leash that had been attached to the collar, pulling at Sweetie’s neck. The little filly wasn’t going to win this. Giving in, she clambered down from her chair, following a few steps behind her Sister, down into the lounge. There, Rarity took her place on the couch in front of the TV, patting the space beside her. Dejected, Sweetie did as she was told, sitting on her flanks beside Rarity.

The TV clicked into life. Some Canterlot fashion show she’d never heard of, featuring a stallion and a mare she didn’t recognize, discussing a style of clothing she didn’t understand. It wasn’t long until she’d zoned out, sinking into herself, focusing most of her attention on ignoring the terrifying mare sat beside her.

This didn’t make sense. Apple Bloom and Scootaloo didn’t know what they were talking about. There was no way this was a normal ‘coming of age’ thing. It couldn’t be… Could it? There was a lot about the world she didn’t understand, so maybe this was normal? Maybe this was just a phase all adults went through with their siblings… it couldn’t go on forever. But perhaps this wasn’t so bad? They were just watching television...

Sweetie quickly stiffened up as her body started to tingle. Every inch of her skin started to warm, as if she’d submerged herself in a slowly heating bath. As her vision of the world tinted blue, Rarity’s bubble of magic that engulfed her had fully formed. In one smooth motion she’d been lifted upwards, turned at an angle, and placed down over Rarity’s lap. Sweetie turned her head to question her sister, but nothing happened. The magic held her still.

Suddenly, the magic began to pull at her jaw. Confused, and unwilling to put up a fight for fear of hurting herself, Sweetie allowed her jaw to loll open. Very soon, though, she was desperately trying to lock it shut again. The ballgag was back.

Unable to combat Rarity’s magic, the little filly could only sit there as the gag came to rest behind her teeth again, the familiar click of the lock shutting behind her head. But just as she had accepted the foreign object into her body, another one was teasing at her. But with Rarity’s magic holding her still, she couldn’t see it. She could only feel it.

The tip of the dildo rubbed cruelly against her asshole, the excessive lubricant dripping down from the shaft, running down the folds of her vagina, forming a sticky pool on the couch. Without saying a word, Rarity began to push the dildo against her little sister’s hole. The filly shook and squirmed with discomfort as the silicone cock teased her ass. Something had to give out eventually, however, and Rarity’s magic wasn’t going to stop any time soon.

Sweetie’s asshole parted in a satisfying manner, slowly consuming the tip of the dildo. Rarity smiled as her little sister yelped in shock - though the poor creature was still shaking like a leaf in a gale.

“Sshh, sshh, thaaat’s it little one. Don’t tense up, just take deep breaths. Relax for your sister, and this will only get easier.”

As one hoof rested over Sweetie’s back, the other lifted up to her head, slowly and lovingly brushing at her mane, like a doting mother reassuring a foal after grazing their shin. Sweetie’s mewls eventually trailed off, her body acclimatizing to the uncomfortable stretching of her rear end, as well as the slow, deliberate pattern of thrusts. The dildo pushed deep into her rectum, dragging along its warm walls, but never going so fast or so hard as to be unbearable.

Confident Sweetie had eased into it, she returned her focus to the television, watching two of her favourite Canterlot designers, Fine Stride and Dainty Boots, discussing their latest fashion creations. It was her dream to work with them some day. They were two of her many idols - and of course, the Canterlot street cred and cash wouldn’t go amiss.

Perhaps deliberate, perhaps distracted by her show, Sweetie could feel the dildo’s pace increasing. With each thrust it pushed that little bit deeper and that little bit harder, the exaggerated base stretching her out that little bit further. The mewls and whines that had once escaped her lips had slowly started to morph into moans and groans, the filling of her rear and the gentle stroking of her mane appealing to the most sinful of her senses. Her whole body had started to grow warmer and warmer as the sensations grew inside her, much of her body tensing and tingling in strange ways - sensations that were fresh in her memory after the events of that earlier night.

Feeling the little filly shake, and listening to the muffled sounds that were clearly trying to form words, Rarity granted Sweetie a little luxury, removing the gag from her mouth.

“Rarity, m-my filly parts feel funny, I-I thi- something’s happenin-g!”

The dildo lurched to a sudden stop. The hoof that had gently brushed her mane lifted away, taking ahold of her chin in that all familiar way, turning her head. This was what Rarity had been waiting for.

“Sweetie Belle, that’s called an orgasm. You need to orgasm. You need to cum. An orgasm is the best feeling a filly like you will ever experience in their life. Once you’ve felt it, you’ll understand. But little fillies aren't supposed to make themselves cum - it's very taboo. Only an adult like me can make you cum. Only your Sister. Do you want that? Do you want to cum, Sweetie? Your Sister can make you feel very good.”

The unicorn smiled to herself as her little sister urgently nodded. Exactly the response she needed.

“Excellent. In that case Sweetie, climb down off the couch, and lie down on the floor. On your back. Mind that dildo.”

She watched as Sweetie did so, before climbing off the couch herself, coming to rest by her sister’s side.

“Now Sweetie, spread your legs for me. I need to see your pussy.”

As the filly did so, Rarity reached her hoof forwards, resting it on her quivering folds. She listened as Sweetie inhaled sharply, the magnitude of her sensations clearly massive. Focusing her attention on Sweetie’s cute little clitoris, she began to rub her hoof back and forth, picking up speed as she went. As if subconsciously trying to match her, as Rarity grew faster, Sweetie grew louder, her breathy moans transforming to a constant high pitched whine.

“Do you want to cum, Sweetie Belle?”

“Y-Yes Rarity, I do!”

"And who's the only one that's allowed to do it?"

"Y-You are Rarity!"

"When are little filles like you allowed to cum?"

"Only when their Sisters allow it!"

“Tell your Sister exactly what you want Rarity to do.”

“I want Rarity to make me cum!”

“That’s it.”

And with that, Rarity rammed the dildo as deep into Sweetie’s asshole as it would go, pulling her other hoof away from Sweetie's clit in the same motion. Sweetie’s head jerked back as the sensations trapped inside her exploded free, cum catapulting itself from her pussy. As one jet followed another, Rarity leaned back to avoid the mess, watching it splatter across the floorboards. She was quite amazed to see just how long the orgasm lasted, Sweetie’s body jerking and twitching as more and more cum shot free. Eventually the spray subsided, leaving only the occasional slow drip running down the inside of her thighs as Rarity slid the dildo free.

“Good mare. Now, you need to go to bed. You have school in the morning - why don’t you take a shower tomorrow for a change? And hey, you’re a pretty young mare, you know that? That collar suits you, really brings focus to your face. You should wear it to school. I think that would be cute.”

Sweetie Belle - far too exhausted to argue for now - wobbled to her hooves, slowly and uneasily making her way up the stairs, back to her room. On more than one occasion her legs gave out from under her, leaving her in a heap on the floor. Each time she lurched back up, a little of the cum that soaked her thighs was flicked loose, splattering on the floor.

As she flopped down onto her bed, two tired hooves lifted up to the collar, fumbling with the catch. Like she was gonna wear it to school. But try as she might, she couldn’t get the catch loose. Giving in, she let her head flop back against the pillow, falling asleep instantly. She’d take it off in the morning.

Little did she know it was locked in place. Rarity was a master in the way of manipulative magic.
