A SLAVE TO HER URGES

PART 4

"Bout time you got here! For a while I thought you weren't going to show!" Diamond Tiara jeered with a leering smirk when she answered the door to her bedroom and allowed the unicorn to walk in.

"Just give me your bucking homework, I'm not in the mood to deal with your horseapples today." The unicorn remarked venomously much to the shock of the bully who gawked at her slack jawed for a moment before she regained her composure.

"Oooh! Somepony's in a bad mood! What's wrong? Get into a spat with your fellow cutiemark losers?" Silver Spoon jeered with a sneer. This turned out to be a mistake.

Sweetie Belle's gaze snapped at the silver furred filly with such fury and anger as her horn glowed green that the bully found herself suddenly very scared as her expression became slightly fearful.

"H-Hey! did you forget that we have those pictures of you still?! No funny business!" Diamond Tiara exclaimed in a less than cocky tone from behind Sweetie Belle.

A tense silence ensued as Silver Spoon gave a soft gulp which could be heard barely over the soft hum of Sweetie Belle's horn as it glowed with magic. After a time, Sweetie Belle's horn stopped glowing as she closed her eyes, took a deep breath, and let it out. "Don't push my buttons today." Was all she said as she trotted a crossed the room and laid down.

"Geez, what happened to make you such a hare trigger, Belle?" Diamond Tiara asked without thinking in a snooty tone as she closed the door behind her.

"Like you'd care. You'd just mock me for it even more. Where's the homework?" Sweetie Belle asked sourly as she glared the the pink furred filly.

"You're right, we probably would." Silver Spoon added with a smirk only to give a unnerved squeak as Sweetie Belle flashed her another glare.

"Relax Silver Spoon, she's not gonna try anything unless she wants us to expose her little secret." Diamond Tiara remarked aloud with a cocky smirk.

"Try me." Sweetie Belle countered with a glare the bully who glared back for a time only to turn her nose up, walk over to her table, grab both sets of her and Silver Spoon's homework, and tossed it at the unicorn, landing right in front of her.

"Get to work and then you can get your short-tempered flank out of my house." She said with an annoyed expression.

"Fine with me." Sweetie Belle replied hostilely as she quickly set to working on the bully's homework despite being sorely tempted to fail the both of them.

"In fact…" Sweetie Belle thought to herself deviously as she looked at Silver Spoon for a moment and proceeded to continue doing the bully's homework…

Sweetie Belle found herself relieved to be out of the bully's house as she left it and with a sense of grim satisfaction to boot. "Can't wait to see the look on Silver Spoon's face." Sweetie Belle remarked darkly with a laugh to boot. The way she saw it, Diamond Tiara was running the show and Silver Spoon was little more than her sidekick and with that thought in mind, she figured a bit of payback was in order.

The unicorn continued to laugh softly to herself as she walked down the sidewalks of Ponyville, seeing but not really paying attention to the numerous amount of ponies she passed. That is until she laid eyes on her mentor's castle and was instantly filled with a sense of guilt and dread.

Unknown to her, a certain Alicorn was watching her from atop the crystal castle's lookout tower and sighed dejectedly as Sweetie Belle trotted away. Twilight walked down the stairs of her tower and into the main throne room with the five seats and looked at its map.

"I wish the map would send me on a quest to help Sweetie Belle but I know there are ponies with far more important friendship problems that need to be fixed." She remarked aloud and sighed once more.

"Yeah… I don't think it works that way, Twilight." Spike remarked from behind her as he walked into the room and sat down in Pinkie Pie's seat.

"I know it doesn't Spike but Sweetie Belle is suffering right now. You saw her didn't you? She walked up to the castle and then walked away. She knows she has magic lessons with me at this time but she's avoiding me and I can't help but wonder why." The Alicorn remarked aloud as she flattened her ears and lowered her head.

"Well, you just got done confronting her for trying to blast Apple Bloom with a spell less than three hours ago." Spike remarked candidly.

"Yeah but I don't see why that would-" Twilight began to say only to cut herself off as a thought occurred to her. The same one that in fact had occurred to her a few minutes after Scootaloo and Applebloom had left her shortly after the confrontation. "Spike, you're close with the crusaders right?" Twilight asked in a wry tone that unnerved the young drake slightly.

"Well, uh… If you mean by close, that I dated Applebloom for a few months last year, then I guess so?" Spike remarked uneasily. He had a feeling he knew where this was going and he didn't like it.

"Excellent!" Twilight exclaimed joyfully as her eyes seemingly lit up with stars in them. "So, I've got a plan and I need your help!"

Upon seeing this, the young drake gave a dreading sigh as he rested his chin upon his right claw. "This won't end well…" he remarked aloud dejectedly.

*knock,knock,knock!*

Came the sound from Sweetie Belle's door to her room at roughly seven o'clock in the morning. "Sweetie Belle! Is it okay if I come in?" Rarity's voice asked from behind the door.

The teenage filly opened her eyes wearily and yawned as she sat up only to notice something poking up from under her covers. It took the filly a few seconds to realize what it was and in the same moment she realized it, the door to her room was being opened.

In a panic, the unicorn channeled magic into her horn and abruptly slammed the door shut which caused her older sister to let out a pained cry from behind the door. "N-Not yet! S-Sorry!" Sweetie Belle stuttered out as she flung the covers off her and stared at her dick as it stood at a attention.

"Why the buck did it happen this time?!" Sweetie Belle whispered to herself in an annoyed and mildly panicked tone.

With a huff the unicorn hopped out of bed and groaned in annoyance as her appendage bobbed up and down, slapping against her underside in response to the gravity forcing it to do so as she jumped out of bed. "Just go down you annoying little piece of-" Sweetie Belle began to say only to notice the door being opened again and used her magic to slam it shut once more electing another pained cry from her older sister.

"I said not yet! Do you know the meaning of privacy, Rarity?! Yesh!" Sweetie Belle exclaimed out in a mildly annoyed tone.
She stared at the door a few moments longer and let out a sigh of relief when it made no motion of being opened again and thus turned her attention back to the problem between her which was throbbing slightly painfully at the moment.

"Where's Scootaloo when I need her?"

A voice in her head said in a mildly joking tone which caused the unicorn to groan irritably. "It's just hormone induced thoughts, ignore them, Belle." Sweetie Belle remarked aloud softly to herself and looked between her legs once more only to gawk at it somewhat curiously.

"Huh...never noticed it was actually black with a few white freckle spots along it before…" She remarked aloud as she sat on her rump and actually looked at it. From her sitting position, her member protruded out in an angle from her face.

The memory of Scootaloo's mouth engulfing it suddenly jolted itself into her mind, causing the appendage to throb even more painfully and the unicorn to impulsively reach out with a hoof only to halt said hoof and place it back on the floor. It was then the unicorn took note of one more thing, her flower was very warm at moment as well.

"Oh, so you're going to join in now too?" Sweetie Belle remarked aloud in annoyance realizing she was growing wetter by the minute as well.

The teenage filly let out a sigh of annoyance. She knew she had two options. The first was to wait and force her thoughts out of the gutter in hopes it would allow her flower and appendage to calm down.

The other was to stimulate herself to orgasm. The trouble with the second was that she wasn't exactly sure if she needed to stimulate both or just one to get both to calm down. Not to mention the thought of stimulating her penis, in her mind, was recognizing it as a part of her. Something she refused to do.

In the end, she thought her first option was the better route. "Okay...picture something that would just completely horrify me." Sweetie Belle remarked aloud as she closed her eyes. Her inner mind raced with thoughts, attempting to find something that would completely turn her off only for the memory of Dinky's puffy pussy lips to jolt to the forefront of her mind which caused the filly to let out a grunt of annoyance as her appendage throbbed and even her flower burned with need at the thought.

"Blast it! Come on! Scary thoughts, scary thoughts! Oh I got it!" Sweetie Belle thought to herself and forced a fabricated image of granny smith into her mind. It was granny Smith alright but it was the mare's teenage younger self and in a lude pose to boot.

"Oh, no! She's hot!"

Sweetie Belle exclaimed in a horrified tone in her head as she attempted to shove the image out of her head. As if being shoved aside like a slide-show slide, the image was shoved to the side and replaced with Scootaloo's face gulfing her cock down to the hilt.

"Oh bucking Celestia blast it!" Sweetie Belle exclaimed out loud in frustration.

This once more prompted Rarity to attempt to open the door once more only for the filly to cock her head around, slam it shut once more, and apply a locking spell to it so she couldn't open it again.

Sweetie Belle once again turned her attention to her throbbing erection and took note of the fact that she was sure she was staining the carpet in her fluids by this point. "May as well get this over with…" The unicorn remarked aloud in annoyance as she leaned herself back, and timidly began to massage her flower.

The effect was instantaneous as the filly arched back slightly and moaned out as pleasure began to course through her body, causing her to lay on her back as she began to massage her clit. Sweetie Belle allowed her mind to wander freely as the images of Dinky's pussy came to the forefront of her mind once more, this however prompted her neglected member to throb painfully as it leaked pre-cum.

Despite her cock begging for attention, the unicorn ignored it as she continued to pleasure her puffy white lips, slowly edging her hoof in between her soaking wet folds, edging a little inside at first, pulling her hoof almost completely out, and shoving a little more in each time she pushed her hoof in.

"Oh Celestia, yes! Make me cum!" Sweetie Belle moaned softly to the imaginary pony she pictured shoving their hoof inside her as she began to pick up a rhythm of shoving her hoof in and out of her soaking wet slit, each time her vaginal muscles clenching on her hoof and almost refusing to let go each time she pulled it partially out.

Suddenly the image of Scootaloo, shoving her orange hoof into the filly planted itself in the unicorn's mind, causing her to arch up and moan out. "Oh… Deeper Scootaloo!" She moaned out, the pleasure coursing through her body now pushing her closer and closer to her much needed climax yet one thing continued to make itself known to the filly and the closer her flower grew to climax, the more her member seemed to throb harder and harder until it was almost impossible to ignore.

"Oh buck it!" Sweetie Belle moaned out as she channeled magic into her horn and began to massage her member with it, stroking it with a rhythm similar to the pace she was shoving her hoof in and out of her white puffy pussy lips.

The added pleasure however was something the filly was no where close to being prepared for as the combined pleasure of her dripping flower and leaking member caused the filly to become lost in a sea of pleasure with no desire to come up for air as she stroked her member in near perfect sync to her hoof thrusting, her climax flooding forward faster than ever.

"Oh Scootaloo, you're going to make me cum so hard!" Sweetie Belle cried out, not even bothering to care if her sister was still at the door or not. She was on the edge now, the point of no return, and without hesitation shoved herself over the edge as she slammed her hoof inside herself as far as it could go and stroked her member at furious speed with her magic now.

At the exact moment the teenage filly climaxed, Twilight appeared in a flash of magic right in front of the filly.

"Sweetie Belle, what happened?! Rarity told me that she heard-" Twilight began to exclaim only to be cut off as the filly's cock exploded and coated the Alicorn's face and mane in her cum. Twilight stared blankly in shock, her face so red it could be mistaken for an apple in Applejack's orchard at the moment as two more strings of the filly's colt-milk splattered against her face while the filly's puffy white vagina gushed its contents onto the carpet, soaking it in a small puddle of her filly juices.

Sweetie Belle who had been rendered temporarily deaf due to her dual climax sending her body into shock, wearily opened her eyes and stared at her mentor's cum-covered face and mane. It took a few seconds but what had just happened finally dawned on the teenage filly as all color drained from her face.

Meanwhile, in Manehattan...

"So dat's how I got my cutiemark!" Babs said with a prideful smile to a group of young blank flanked foals.

AIIIEEEEEEEEEEEEEE!

Came a voice that seemed to echo from thousands of miles away yet she could hear it as if she was barely a few feet away.

"Sweetie Belle?" Babs remarked aloud with a bewildered expression as she pondered how it was possible to hear the filly from this far away from Ponyville.

Author's Note

Oh dear...somehow I feel more sorry for Twilight at the moment than Sweetie Belle...I wonder why?
