A SLAVE TO HER URGES

Part 1

As Sweetie Belle walked to her first period class, she thought over what had just happened. Diamond Tiara and Silver Spoon somehow found out her secret. She was now at the mercy of the two bullies every whim, and to make matters worse, Silver Spoon seemed to be bent on making the unicorn her own personal sex toy.

Sweetie Belle could only pray the two wouldn't cause her too much more grief than they already did before they found out. Being forced to do their homework, she could handle. Being alone in the same room as the two, who knows what they might try?

"They might try to get frisky with with me. I can only imagine how that would go." Sweetie Belle thought to herself dismally yet in that same moment another thought crept into her mind.

"Maybe that wouldn't be such a bad thing…"

A voice said aloud in Sweetie Belle's head, it was her voice yet at the same time it felt as if it wasn't. Sure, it sounded like her but to the unicorn filly, even if it sounded like her, she would never say or think something like that...would she?

"After all, I got Scootaloo to give me a Blowjob yesterday, who knows what I could get those two bullies to do to me."

That voice again...Sweetie Belle didn't like it but for some reason she found the voice's words alluring. As if they were speaking some kind of hidden truth. Was she finally losing it? Probably not. After all, the voice wasn't telling her what to do. It didn't have some kind of magical control over her mind but it was alluring, very alluring.

Suddenly, the filly stopped in her tracks and craned her neck between her front hooves to look at her invivale appenage. "Stop putting those thoughts into my head you little nuisance!" Sweetie Belle hissed at her hidden appendage before she lifted her head back up and continued walking to her first period class.

Once first period had ended, Sweetie Belle went to her locker only to see her two best friends already at their lockers. "Hey, Bloomy, Hey Scoots." She said to each filly as she walked up to her locker and opened it to put away her first period class books.

"We missed ya on our way to school this mornin'. Somethin' hold ya up?" Apple Bloom asked curiously as she closed her locker.

"Oh yeah, my sister. We got to talking about her graduation party and-"

"Ahem!"

A prissy voice exclaimed from behind the unicorn which could belong to none other than Diamond Tiara.

"What the hay do y'all want?" Applebloom asked with an annoyed expression which was mirrored by Scootaloo.

"We just wanted to have a chat with Sweetie Belle is all." Diamond Tiara replied with a sneer.

"Yeah, without you two cutiemark losers!" Silver Spoon chimed in.

"If you want to say anything to Belle, you can say it in front of us! Isn't that right, Sweetie Belle?" Scootaloo with a glare at the bullies then a smile towards the unicorn.

Sweetie Belle bit her lower lip as her eyes shifted back and forth nervously before she finally spoke. "Um, A-Actually. I think it might be best if you two head onto class, I'll catch up since we all are in history class together!" Sweetie Belle said with a nervous smile.

"Yer serious?" Apple Bloom asked incredulously with a look of disbelief that Scootaloo also mirrored now as the two gawked at their friend.

"Y-yeah! Don't worry, they just want to talk to me about a few things!" Sweetie Belle replied doing her best to sound convincing.

"O-Okay…" Scootaloo replied in an unsure tone just before she closed her locker door and walked away with one last curious glance before she left sight.

"If yer sure. See ya in class." Applebloom replied with a less than convinced expression on her face as she turned and left the three alone.

Once the two were gone, Sweetie Belle's facial expression turned sour as she looked upon the two bullies. "What the buck is it now?" She asked with a glare.

"Oooh, somepony has suddenly grown some balls!" Silver Spoon jeered which caused Sweetie Belle to give a fleeting yet panicked glance around herself.

"A little paranoid much? Anypony would just view that as banter. They wouldn't take it seriously you know." Diamond Tiara remarked with a smirk followed by the two bullies laughing at the unicorn's expense.

As much as Sweetie Belle hated to admit it, they were right. However, she also knew that they were playing off her fears of anypony finding out her secret too. With a huffing sigh, she spoke once more. "What is it?" She asked in a much more polite tone this time around but it still held her disdain and annoyance of the two bullies in her voice.

"We just came to remind you of rule one of our agreement." Diamond Tiara replied with a smirk.

"Annnd! We want you to deliver this letter to Rumble for us." Silver Spoon added as she pulled a letter out of her saddlepack and showed it to the unicorn whom levitated it over to her via magic.

"Why don't you two just do it yourselves after you've finished bucking him for the day?" Sweetie Belle quipped with a smirk much to the chagrin of both bullies.

"I'd watch my words carefully if I were you." Diamond Tiara remarked aloud threateningly as she pulled an envelope out of her saddlepack. "Or these will hit every major newspaper in Ponyville." Diamond Tiara added which caused the unicorn's eyes to widen in fear.

"And don't even think about burning these! We had them coated in anti-magic plastic!" Silverspoon added with a sneer.

"Okay, Okay! I'll give him your stupid letter! Just put those away!" Sweetie Belle replied in a panicked yet soft voice to the bullies.

"You better." Diamond Tiara replied as she put the envelope away. "Come on Silver Spoon, we're going to be late for class." She said as she turned about face and walked away.

"You think she knows the photos in the envelope were fake?"

"They won't be for long…"

"Here. It's from Diamond Tiara and Silver Spoon." Sweetie Belle said briskly as she shoved the letter into Rumble's hooves about three minutes before history class started.

The colt quickly read the letter before he looked at Sweetie Belle. "I feel sorry for you." he said with a smirk.

"What's it say about me?" She asked with a worried glance.

"Oh nothin'. Just that I've been relieved of my services to them and that you're my replacement." He replied quietly as his grin grew even wider if possible.

"Services? You mean they blackmailed you too?" Sweetie Belle asked in a hushed tone.

Rumble merely chuckled to himself as if doing his best to contain his sheer joy at the cost of Sweetie Belle's misfortune. "Let me put it this way, hope you're skilled with your tongue." he remarked softly and unable to contain his joy any longer, gave a joyful "Whoo-hoo!" as he ripped the letter in half and took his seat.

These words weren't too comforting for the unicorn as she gave a soft gulp. She knew exactly what he had meant and if they forced her to do the same thing…

"I can't believe I got so lucky! I can't wait to dive face-first into their-"

"Shut the buck up you little nuisance!" Sweetie Belle exclaimed softly yet it was loud enough to get a few curious looks at her which caused her to blush softly before she quickly took her seat next to Apple Bloom.

"What the hay was that about?" Apple Bloom whispered as the teacher walked into the room.

"The letter?" Sweetie Belle asked.

"That, and yer little outburst." Apple Bloom asked curiously.

"I'll explain later." Sweetie Belle said dismissively as she purposely turned away to levitate her book from her saddlepack to her desk.

Despite Apple Bloom and Scootaloo trying to get her attention the whole period to ask her what the heck was going on, she purposely avoided replying to them by note or otherwise using the fact they were in class as an excuse.

Once again, the three fillies filed in for gym class and Sweetie Belle could avoid the topic no longer.

"Out with it, Belle! What the hay is up with you and the snob squad!?" Scootaloo demanded as she looked at her friend suspiciously.

"Yeah! Since when did ya become their personal delivery filly?!" Apple Bloom chimed in as the three walked to their usual places to be called up to run laps around the track.
Once again, Sweetie Belle bit her lower lip, hesitating on if she should lie to them or not. Knowing her friends, they wouldn't take Sweetie Belle being blackmailed sitting down and try to help her get them off her flank but on the other hoof, if Diamond Tiara and Silver Spoon found out she had told them, her secret would be on the morning edition of the next day's Ponyville newspaper for sure.

Before she could reply however, Big Macintosh walked up to the unicorn and gave her a letter. Curious, she opened it and read it. "I've been excused from gym class?" She asked curiously.

"Eee-Yup!" Big Macintosh replied though he didn't seem happy about it.

"Are ya sick or somethin'?" Applebloom asked curiously.

Though the signature on the paper was from Principle Harshwhinny herself, something felt off about this letter. Regardless she used this as an excuse to quickly make her leave of the gym class ground much to the confusion of Apple Bloom and Scootaloo.

"Somethin' stinks." Apple Bloom remarked with a scowl.

"You said it!" Scootaloo concurred as she narrowed her eyes at the unicorn just before she left sight.

"Oops, my bad!" A unicorn remarked with a blush.

"Not you, Dinky!" Scootaloo replied to the unicorn filly with an annoyed look before she looked back at where Sweetie Belle had just been.

"Ya think she's been blackmailed?" Apple Bloom asked softly to her friend.

"I'd bet my november edition of Playfilly Magazine she has." Scootaloo replied in a firm tone.

"You've got a subscription to a dirty magazine?" Applebloom asked allowed in shock.

"Uhhh… Oh hey look! We're up!" Scootaloo began to reply with a crimson red blush just before Big Macintosh blew his whistle at the two and used this as an excuse to avoid the topic.

Sweetie Belle entered the filly's locker room to open her locker and sighed. "How am I going to keep this a secret from them?" Sweetie Belle remarked aloud and sighed again. She had never kept secrets from her fellow crusaders. But she couldn't risk this. Not only was her social life on the line but so was Twilight's reputation. Not to mention, she could only imagine the backlash Rarity would get for registering her as a "filly" with the school. "Do they even have a name for what I am?" Sweetie Belle mused aloud curiously as the thought ran through her mind of what she would be labeled as while she stood to her hind hooves to reach for her saddlepack she had left on top of the locker, the thought to use her magic not crossing her mind due to how deep in thought she was.

"Dick-Filly comes to mind." A voice suddenly said which caused the unicorn to whirl around with her back now to the locker door to see Silver Spoon standing behind her.

"Oh, it's just you." Sweetie Belle remarked with a relieved yet annoyed expression. "Let me guess, you and Diamond Tiara forged the Gym excuse letter?" Sweetie Belle remarked realizing that it was more than coincidence that she was here right now.

"Actually, it was just me." Silver Spoon replied as she casually trotted a few steps to the locker next to her.

Upon hearing this, the unicorn gave a soft gulp, recalling exactly what the silver furred filly's intentions were for her and the letter she gave to Rumble earlier. "I-I thought Diamond Tiara said she was going to keep you on a leash?" Sweetie Belle remarked nervously as the bully batted her eyes at her.

Upon hearing this, Silver Spoon rolled her eyes and groaned. "It's always about her! I have needs too ya know!" Silver Spoon exclaimed angrily before she suddenly calmed herself, quickly trotted up to Sweetie Belle, rose herself so she was standing on her hind hooves and slammed both front hooves against the locker door Sweetie Belle was standing in front of so that both her front hooves laid against each side of the unicorn's head.

This action had caused the unicorn to flinch as she jolted her face to the side and slammed her eyes shut. After a moment she hesitantly opened them and turned her head to look in front of her to see Silver Spoon's face mere inches from hers. "And right now, you've got the one thing that will scratch that itch under my tail!" She said in a sultry tone as she smirked at the unicorn.

"Are you in heat or something?!" Sweetie Belle blurted out without meaning to with a mildly scared yet curious face.

"If I was, would you be more inclined to buck me?" Silver Spoon asked in a sultry tone.

"You bet I would!"

Sweetie Belle growled under her breath. It was that voice again.

"I can't believe I'm even considering turning down an offer to get laid!"

Sweetie Belle gulped loudly upon hearing her voice say these words. The voice had a p- Wait, no it didn't! "I refuse to be a slave to my hormones!" Sweetie Belle thought to herself dramatically.

"Am I really going to turn down the chance to lose my virginity to a filly?"

"You bet your annoying existence I am!" Sweetie Belle thought to herself as she channeled magic into her horn and moved Silver Spoon away from her.

"H-Hey! What the buck do you think you're doing?!" Silver Spoon exclaimed in outrage at the filly as she flailed helplessly against the unicorn's magical hold.

"If you don't want Diamond Tiara to find out you tried to jump me when she said you weren't allowed to, I suggest you walk away no sooner I put you down." Sweetie Belle said in a threatening tone.

"Like she'd do anything to me for trying to jump your dick!" Silver Spoon retorted with a glare.

Upon hearing this, a nagging thought occurred to her. Would she? Just how much did Diamond Tiara actually hold herself to her own word? After all, if she blackmails ponies on a regular basis, whose to say her word is any good at all? "I'll have to take a gamble." the unicorn thought to herself and quickly thought up something.

"That's funny, because Rumble would say otherwise." Sweetie Belle bluffed with a smirk.

Her bluff seemed to work as the bully's cocky expression faded and revealed a scowl. "Fine…" She replied in a defeated tone at which point Sweetie Belle set her down. "Just remember, the moment you slip up, I don't want to hear one word of protest as I shove that dick of yours inside me!" She added in a threatening tone as she walked away and left the locker room.

"Don't worry, I won't." Sweetie Belle remarked though this was out of earshot of the bully as she quickly left the locker room and glanced up at the clock. "Thirty minutes left in the period. This voice in my head is becoming about as much of a nuisance as this annoying thing between my legs, I need to see if Twilight can silence it." Sweetie Belle thought to herself as she quickly glanced about herself to make sure nopony was looking, channeled magic into her horn, and disappeared in a flash of magic.

"And this book goes here." Twilight hummed aloud as she used her magic to place a book only to suddenly go wide-eyed as Sweetie Belle suddenly appeared above her.

"Soorrrrry!"

Was the only thing Sweetie Belle could shout before she impacted with the Alicorn.

"Just what in Equestria were you thinking, young filly?!" Twilight asked as she used an icepack to nurse the bruise on her head. "A couple more inches high and my horn would have impaled you!" She added as if to drive the point home that what she had done was dangerous.

"I know, but this is important! I wouldn't have used a homing spell if I had known you were in the castle library!" Sweetie Belle said defensively.

"What's so important that you'd teleport to me during school hours?" Twilight asked with a curious glance at the unicorn filly.

One quick yet detailed explanation later and the Alicorn had to resist the urge to burst out laughing.

"What's so funny?! This voice sounds like and is saying things I'd never say!" Sweetie Belle exclaimed in annoyance.

The Alicorn cleared her throat and calmed herself before speaking. "Did you ever come to think that it wasn't some other voice but your very own thoughts?" Twilight asked with a knowing look.

"Of course I considered that but-" She began to say only to cut herself off before she spoke of what Silver Spoon tried to do. The last thing she wanted was for her mentor to get involved in something that would destroy her reputation.

"But what?" The Alicorn asked with a curious look.

"But I just know it wasn't me!" Sweetie Belle finished her statement yet differently than originally intended.

"Tell me something then, before you started having fantasies about fillies, what did you tell me in confidence that you'd do to Rumble if you had the chance?" Twilight remarked with a smirk.

"H-Hey! That's not fair! I was going through my first heat!" Sweetie Belle flustered with a blush.

"Fair or not, the thoughts you're just described to be are no different than that. Our hormones can be powerful influences on our rational thinking." Twilight explained calmly.

"But I'm not a colt!" Sweetie Belle nearly shrieked at the Alicorn.

"No… but you do have colt genitalia." Twilight replied calmly to which Sweetie Belle huffed as she sat on her rump and crossed her front legs across her chest in annoyance.

"Don't see how that can make me consider bucking Silver Spoon." Sweetie Belle muttered aloud.

"What was that?" Twilight asked curiously to which the unicorn filly quickly replied with a panicked: "Nothing!"

"My point is Sweetie Belle, that spell you cast when you were ten years old didn't just give you a colt penis, it gave you all the plumbing that goes with it. You can, in fact, impregnate a filly. If you choose to engage in-"

"I know this! You explained this to me like ten times already!" Sweetie Belle exclaimed in annoyance, cutting off the Alicorn.

"Well it seems like you keep forgetting this. Or rather, like to suppress this information." Twilight replied with a mildly annoyed look at the filly.

"Of course I'm suppressing it! I would like to go about my life pretending this thing doesn't exist!" The unicorn retorted and sighed.

"But it does exist. The sooner you accept it as apart of you, the sooner you can get on with this part of your life." The Alicorn said wisely.

"So, what? I'm just supposed to walk around town without my cloaking spell on? Is that what you're hinting at?" Sweetie Belle asked with a glare at the Alicorn.

"Well, I didn't say that. Of course you wanted to, we would have to make the proper preparations and-"

"Not. Going. To. Happen." Sweetie Belle said pointedly.

Twilight sighed aloud as she ran a hoof along the back of her head. "Well, you should head back to school. You're going to be late to your next class if you don't leave soon.”

"Fine." Sweetie Belle replied as she stood to all four hooves. She wasn't exactly convinced that her own voice said those things but she wasn't about to argue it any further with her mentor. "I can't believe she even humored that thought! Didn't she realize I was being sarcastic when I said that?! For as smart as she is, she sure doesn't consider the consequences of-" Sweetie Belle thought to herself in an annoyed tone until a scroll was put in front of her.

"What's this?" The unicorn asked curiously.

"An infertilization spell for both genders." Twilight said with a smile.

A blush washed over the unicorn's facial features once she heard these words. "Y-You can't be serious!" Sweetie Belle flustered out still beat red at the mere idea of using this spell under any circumstance.

"Dead serious." Twilight replied firmly. "You can never be too prepared and if you find yourself caught up in the heat of the moment, this can save you or another filly from making a mistake you'll regret later." The Alicorn added.

"Have a little faith, Twilight! I have better control over of myself than that!" The unicorn replied as she used her magic to toss the scroll to the floor, turned around, channeled magic into her horn, and disappeared in a flash of magic.

The Alicorn was just about to pick up the scroll with her magic when Spike walked into the library. "Was that Sweetie Belle?" He asked curiously.

"Yeah, she wanted to talk with me about something that was bugging her." Twilight replied tactfully as she turned to pick up the scroll once more only to find it was missing.

"Looking for something, Twilight?" Spike asked curiously as he looked in the direction the Alicorn was looking.

"No, not anymore anyways." Twilight replied with a knowing look.

Author's Note

Just as a heads up for the "voice" in Sweetie Belle's head in case any confusion may come about. I did my best to think of a method of portraying how one's hormones may influence their thoughts and the voice in italics was the best I could come up with.
