Learning to Play Her Instrument

Octavia was an average pony, at least, that’s what she liked to tell herself. Growing up, her parents had told her not to think of herself as different from any of other pony. And though she knew they meant well at the time, as she grew up, she began to realize those two great differences that set her apart from her peers.

The most obvious was an accident of chance.

Octavia loved music. During her youth, she had flirted with the classics and as she grew older, these flirtations developed into a full-blown love affair. By the time she was in high school, she had distinguished herself as a cello virtuoso, a fact and even had won her some acclaim among her peers, which she took great pride in.

The other was an accident of birth.

The young cellist rubbed her eyes as she stumbled into her college dorm bathroom, splashing some water on her face before looking herself over in the mirror. She was twenty-two now, and it definitely showed.

No longer the thin, frail girl she had been in High School, she had matured into a fully grown woman. Aside from her brilliant eyes and long, straight hair, she had curves in all the right places. Especially her breasts. Heavy, with the right amount of perk; unassuming, but extremely tender to the touch. Octavia had been well endowed in this respect, and if other girls were more modest about their bodies, Octavia certainly could understand. It was only natural, considering how careful her parents were to instill in her the virtue of modesty.

“If that’s all a woman has to offer, then she offers very little,” her mother was fond of saying. And she was right. She was more than just a pair of nice tits and a pretty face, though she certainly lacked nothing in either department. She had something that meant more than that – passion and a drive for excellence. It had been what carried her through her Bachelor’s, and would see her finally achieve her Master’s and one day, with any luck, be accepted into the Royal Orchestra.

“Just two more years, then on to first chair cello,” Octavia murmured to herself as she slipped on her bra before being reminded of her other inheritance…the monstrosity.

It dangled there between her legs like some unsightly abomination; its massive, unnatural weight causing a hollow echo every time it hit her thighs.

Octavia often mused to herself that if she had been born a colt, she might have considered herself unusually blessed. As it were though, this ‘blessing’ was more of a curse. When she had been born the doctors were at a loss to understand it. Nothing about it made sense, not least that she was, in body, manner, and thought, a girl.

Her parents were rightfully concerned. Thankfully the doctors had offered a solution – a magic potion that would conceal her uncomfortable disposition and give her, by appearance and feel, what a girl was supposed to possess. Of course, there were drawbacks, which Octavia became acutely aware of growing up.

The potion itself was expensive, having been concocted from a variety of rare herbs and elements. It wasn’t always possible to afford the prescription and so, at times, Octavia found herself having to cope with the situation as best she could.

No skinny jeans or short skirts for me.

Then there was the potion’s physical limitations. A single dose only tended to last around eighteen hours, which often found Octavia with an unexpected surprise when she woke up in the morning.

No sleep overs either.

What was worse – it often seemed to have a mind of its own. And while the potion was effective, it didn’t always work the way it was intended. Sometimes an especially severe episode of stress or nervousness caused the potion to wear down early. This had led to more than one embarrassing incident in Octavia’s adolescence, much to the cellist’s eternal regret and shame. Nevertheless, it had also made her acutely aware of her own emotional limits and endurance and had allowed her to strengthen both as a consequence.

Octavia popped off the potion’s cork with one swift motion and downed it in one go, shuddering at its acrid taste. Years of taking that vile substance never seemed to make it any more pleasant.

The effects were almost immediate. Octavia felt her bare body shiver as the great girth of her prodigious package began to recede, and in a moment, nothing was left to indicate that she was anything but a full and true woman.

At least – that’s what should have happened.

Instead, Octavia felt…off. It started with a tingling sensation in her fingers and toes and then worked its way up her arms and legs.

I’m having a heart-attack!

A feeling of panic swept over Octavia as she tried to make for the door to reach her cellphone, but found her efforts were in vain. Her entire body was numb and she could hardly move. The tingling continued, but oddly, there was no pain. Octavia didn’t know if this was a good or bad thing. Instead, the cellist sat on the toilet, trying her best gain her balance and hoping the sensation would wear off.

Good Gods, this is where they’re going to find me!

Octavia wasn’t sure what she found more upsetting: the fact she was dying or the thought of being found dead naked on the toilet.

Well, I suppose there are more undignified ways to go.

But to her surprise, she did not die!

A moment passed and the sensation died away, leaving Octavia stunned but otherwise unhurt.

That was strange.

Octavia felt her wrist– normal pulse. She was thankful to have taken basic first aid now. She got up and looked herself in the mirror. The potion hadn’t worked. The monstrosity was still there, but now it felt different. She felt different.

That was when the heat followed. Octavia felt as if her entire body was on fire.

“What is going on!?”

She rapped her hoofs on the tile, tears flowing down her cheeks. Had she been poisoned? Was this some sort joke? She didn’t know, but what she did know what that it was something terrible.

She felt powerless. She felt weak. She felt...horny.

Octavia tried her best but couldn’t stop from shivering as her mass touched the cold exterior of the wall tiles.

She was fully erect.

The bulbous mass of her cock strained and pulsed, like some unnatural outgrowth or tumor. Octavia had always had a good handle on this but this was different. It felt like it was independent of her thoughts, of her actions. When she touched it, she nearly fell down, gasping, the sensation coursing up her spine like lightning.

Octavia felt her face flush red. She hated herself for this, and wasn’t even sure she wanted to, but she continued to run her fingers over it, flexing the sheath over her massive stature, wishing she had the willpower to stop.

But it just felt so damn good.

The cellist huffed and panted, the mirror on the wall quickly fogging. She was lost in a tidal wave that had broken all of her inhibitions. Repressed memories and feelings came back to her and were washed away by the torrents of pleasure coursing through her body.

But one memory gave her pause.

Octavia found herself back in the girl’s locker room at Canterlot Middle School. The rest of the girls were changing after a long workout. She was thoroughly exhausted and retreated, as she normally did, to the corner where she thought she was out the way.

She reclined her arms on the wall, feeling the cool air from the AC above her, before she felt something slip down around her ankles and a sudden chorus of gasps filled the air, followed by laughter.

Octavia wasn’t even sure what had happened until she realized she was exposed – with the monstrosity plain for all to see. She swung around to see the perpetrator, only to be greeted by that sly, malicious face grinning at her wickedly with that air of smug satisfaction that only a sadist could stomach.

She only got a brief glance before she tried to collect herself the best she could and ran out of the locker room, the hot tears burning her eyes, filled with a total sense of embarrassment and anger.

And as the cellist stroked her massive horse cock, there was only one thing that she could think of:

Sunset bucking Shimmer!

Octavia began to feel hatred mixed with lust begin to rise within her as she imagined that smug look being wiped off her face if she had her way with her.

“Thought you were so tough,” Octavia huffed. “Who’s crying now, huh? Suck my British balls.”

The thought filled Octavia with rapture. To give that bully a taste of her own medicine. To have her in total submission and to see the look of desperation on her face instead!

Octavia could hardly contain herself and began muttering obscenities as she stroked herself, unable to sate her perverse satisfaction at her fantasy before she realized she had gone too far.

The cellist felt her eyes go blurry as her throbbing cock convulsed and the world seemed to melt around her in a moment of pure satisfaction, her tongue hanging from her mouth.

When it was all said and done, Octavia wasn’t even sure what had happened, but as she began to regain her senses, the awful extent of what she had done became clear to her.

The room...was coated…in cum.

Octavia recoiled in horror and dismay.

It was everywhere. On the floor, the toilet, the bathtub. In the corner, there was a great heap of it gathering as it ran off the walls and collected on the floor. Octavia, to her chagrin, reached up and felt the hot sticky substance as she ran her fingers through her locks.

It’s in my hair!

Octavia immediately jumped up to clean it but then remembered, looking up at the cum-coated clock, that her class would be starting soon.

Buck my life!

She hastily pulled out the dust pan and broom and tried sweeping it up, but despair set in as she realized she’d never be able to clean it up and herself in time.

I’ve never been late for a class in my life! What are they going to say! Oh! Stupid girl! How could you have done something so foolish!

Octavia threw the cleaning instruments on the floor, feeling helpless before she heard something in the distance.

Footsteps. Coming up the stairs.

She looked back up clock. A quarter past seven. That meant that…

Vinyl is getting off of work!

Octavia panicked.

“Think, Tavi, think!”

The footsteps echoed louder as they approached.

“Ah...Buck it! There’s no time!”

Octavia hastily donned her discarded sleeping wear and shoved everything inside the sullied bathroom, just as she heard the rattle of keys and creak of the front door opening.

“Vinyl! So good to see you!”

The DJ was in a terrible state. Her bloodshot eyes were visible, even before she removed her glasses and hung them on the wall. Vinyl limped along the floor, more than a little out it, Octavia could tell.

“Hey Tavi,” she grumbled. “What are you doing here? Don’t you have class, or something?”

“Oh ha ha, you’re right. Silly me. Well it turns out Dr. Honeyfeather cancelled it. No class today. None at all, in fact.”

“Huh…” the DJ shrugged. “Doesn’t sound like her, but whatever.”

“I bet you’re really tired! Here, let me fix you something relaxing and maybe you can go to sleep for the next 12-14 hours, perhaps? And definitely not go into the bathroom.”

Vinyl sniffed the air, her lethargy suddenly forgotten.

“What is that smell?”

“Smell! What smell? What does it smell like?”

“Like…like…ammonia?”

“Oh um…well that makes sense. I was doing some uh…cleaning! Yes! Cleaning! Dirty thoughts – er, I mean, floors! Dirty floors!”

Vinyl looked at her perplexed.

“You’re acting a little strange, Tavi. Are you sure that ammonia didn’t go to your head just a little?”

“To my head? Perish the thought! I just work so hard and knew you’d appreciate the effort because I don’t feel like I show you enough attention and so I wanted to make it up to you.”

Vinyl blinked.

“Riiiiiight. I’m just gonna a take quick trip to the…”

Octavia slammed her arm in front of the bathroom door.

“You can’t go in there! I – uh – uh – haven’t finished yet! You might slip and hurt yourself.”

“I’ll be careful…”

“No! You don’t understand. How could I live with myself if you were to get hurt? I couldn’t let you needlessly endanger yourself, could I?”

“Tavi, are you on drugs?”

“Drugs! Yes! Drugs, that’s it! Drugs! I’ve got lots of drugs. I just shot up like half-an-hour ago! I’ve a whole meth lab set up in the bathroom. You really shouldn’t go in.”

“Oh I get it.”

Octavia felt her heart drop.

“Get? Get what?”

“You’ve just taken a huge dump and don’t want me to suffer. I gotcha. Trust me though, Octy, there ain’t much I can’t handle.”

She went for the knob but Octavia fell to her knees.

“Please, Vinyl. For the love of Harmony, don’t go in there. I’m begging you!”

“What is wrong with you? What could be so bad that you could possibly…want to…hide it?”

The DJ stopped in her tracks as she opened the door, unsure of what she was seeing. The war-zone that was their former bathroom left her speechless, as did the pungent smell that threatened to push her over.

“W-what is this? Is this…”

She touched some as the sloppy goo trailed down her fingers.

“Is this cum!?”

Octavia began to cry.

Vinyl forgot the sordid scene momentarily as she reach and grabbed a roll of (miraculously untouched!) toilet paper and sat beside her roommate, handing it to her. Octavia wiped her eyes and blew her nose as she tried to compose herself.

“Oh Vinyl, it was awful. I woke up this morning like I usually do and took my medication, but something went wrong. Terribly wrong. I couldn’t control myself. I started touching my…my…”

Octavia felt a fire rise within her as she threw the toilet paper roll across the room.

“Why did this have to happen to me!? Why couldn’t I have just been born like any other girl? Then I wouldn’t have to deal with this. I hate having this…this…thing between my legs!”

Vinyl bit her lip, unsure of what to say as the cellist lamented.

“C-can I see it?”

Octavia recoiled.

“What? No! Certainly not!”

“Oh come on Tavi, you just blew a load in our bathroom that puts Mt. Vesuvius to shame! The least you could do is show what caused it. That thing has got be impressive.”

The fire within Octavia’s stomach rose to her cheeks.

“I…uh, well, um. I’ve never heard anypony use that word before to describe it.”

Vinyl chuckled.

“No worries, Tavi, I’ve seen my fair share of dicks before.”

Octavia glanced down, pursing her lips as she rubbed her elbow.

“You…you promise not to laugh?”

“Promise.”

“Alright then…”

The cellist took a deep breath before suddenly jerking down her pajama pants and knickers.

Silence.

Octavia refused to open her eyes to see her friend’s face.

“Well? What do you think?”

“Sweet pony Jesus! It’s huge! It’s the biggest cock I’ve ever seen! How do you even walk with that thing!?”

Vinyl howled with laughter.

“You said you wouldn’t laugh!”

“You’re right…you’re right,” Vinyl said, trying to regain herself. “I just wasn’t expecting it, is all.”

Octavia puckered her lips indignantly.

“Happy now?”

“Can I touch it?”

“No!”

“Come on, Tavi!” Vinyl whined.

“No, don’t ‘Come on, Tavi’, me. I’ve been through quite enough already this morning, thank you very much.”

“But look at it! It’s bucking massive!”

“Vinyl, I don’t have to be reminded of the very large horse dick that I’ve seen every day of my life since birth!”

“Wait, you were born with this?”

Octavia sighed.

“It was an abnormality. It could have been removed, but my parents objected. The doctors gave me a potion to take to ‘make it go away’ – at least for a while. I take it every day. But this time it didn’t work and…it was horrible, Vinyl. I started touching myself and well, you see the result.”

“Have you never explored yourself?”

Octavia shook her head.

“My parents told me I shouldn’t. So I never did.”

“Never?”

“Never. And now I’m not even sure what’s going on or what to do. I’m afraid to take anymore potion either. After what just happened, I don’t know what to expect anymore. And I can’t go to class with…this!”

Octavia pointed to her exposed member, which was now twitching.

“Tavi,” Vinyl began, seriously. “Are you still horny?”

Octavia looked away.

“Yes,” she replied in a small voice.

“It’s not a bad thing, you know? Everypony gets this way sometimes.”

“I know, but it makes me feel dirty.”

“Octavia, listen to me.”

The cellist felt odd hearing Vinyl say her full name. It almost sounded foreign since she wasn’t even sure she had ever heard her call her anything but ‘Octy’ or ‘Tavi’.

“There is nothing dirty or wrong about it. You shouldn’t feel any shame or guilt because of this. You have needs – we all do – hell, I do for sure. But you can’t live your whole life ashamed, you know? You have to love yourself – the real you – despite what anyone else says.”

Octavia nodded, taken a bit off guard by the DJ’s oddly inspirational homily.

“You’re right, Vinyl,” she said, wiping away what remained of her tears. “Perhaps I’ve been repressing this part of myself too long.”

“That’s the spirit, Tavi.”

“And you know what else?” she asked, getting to her feet. “I don’t care what anypony else thinks!”

“Buck yeah!”

“I’m horny as hell and I’m not going take it anymore!”

“You go girl!”

“I’m horny as hell and I’m not going take it anymore!”

“Hallelujah!”

“I’m horny as hell and I’m not going take it anymore!”

“Preach it from the mountain top!”

“Get on your bucking knees!”

“Wait, what?”

Octavia blanched as Vinyl seemed to hesitate.

“Oh, um…I’m sorry. I was just going along with it. I-I though that’s what you wanted.”

“Well, I mean, geez Tavi, I know we’re friends and all, but…”

“Oh come on, Vinyl.”

The DJ smirked.

“Now who’s the one whining?”

“Well, if it means anything to you, you’re one of the few ponies that I’ve ever told this about. I trust you. You’re special to me.”

Vinyl rolled her eyes.

“Yeah, yeah, I get it. You better be thankful you’re cute, Octy.”

The DJ cautiously approached and gripped the length of the cellist’s member, its size as daunting as it was enticing.

“It’s as big as my arm,” Vinyl said chucking, comparing the two side by side.

Octavia smiled, the feeling of nervousness slowly replaced with a faint sense of mirth at the situation; her best friend below her and she with a raging hard-on.

“Be gentle,” she huffed as Vinyl began to tug on her sheath, playing with it as rubbed the head.

Octavia felt her body shiver, her heart pumping; tingles running up and down her spine. She breathed harder, her heavy breasts heaving as her roommate grasped her gargantuan girth.

Deep moans escaped from her lips; a bead of sweat rolling down her cheeks. Octavia felt so dirty, like this was breaking all of the rules and felt repulsed, but at the same time, she felt liberated, like a great burden had been thrown off her shoulders. She actually felt pleasure. True pleasure. The pleasure of being touched by another pony and sharing that intimacy that she had been denied all of her life. And for the first time, Octavia realized she was happy.

The cellist bit her lip, her voice a series of low groans.

“Vinyl, please, don’t stop. Oh, yes. Please, suck it.”

The DJ looked up at her friend, cheeks red and a glazed look in her eyes, lost in a drunken ecstasy. She had never seen her friend like this. Octavia had always been quiet, fussy, and reserved; like she always had something to hide. She did have something to hide – a burden she had carried all through her life. A source of shame and guilt.

It dawned on her what a leap of faith this must have been for Tavi. To put aside everything she had ever been told about who she was and embrace her true self with the one pony she felt she trusted the most. It was really touching.

Vinyl felt something pull on her heartstrings; a mix of moving passion and lust. She wanted to make this special for Octavia; to give her a taste of something she had regularly enjoyed; to take her innocence.

Going to blow your mind, Tavi.

The DJ pulled her friend’s massive cock over her head and began to fondle her balls – those just as equally large and heavy. She massaged her sack, running her tongue over her testicles, knowing full well she’d never fit either in her mouth wholly.

Octavia gave a pleasured groan, her entire body shaking.

How have I never felt this before? Is this what I’ve been missing out on all this time?

She remembered how she used to listen to colts talking in high school; how they said it was the best thing in the world. She never understood what they were on about, how they would crave it. It was just sex, after all.

But it was so much more.

All the wasted years!

Octavia felt a sadness thinking of all the opportunities she had missed, all the advances she had passed. If only she had known. If only she had known.

“Suck it, Vinyl. Take my balls in your whore mouth.”

That wasn’t her. But it was her. The her that she always knew she was. The her that had always frightened her, that haunted her dreams. The her she had repressed, locked away, and tried to forget about. The her that even her parents tried to make go away. But this was her – the real her. The her that wanted to be free.

Vinyl moaned in approval, buzzing her lips on her sensitive sack. Octavia bit her lip so hard that she was afraid of drawing blood.

“Bucking hell, Vinyl, stop being such a tease!”

The DJ smirked in her cheeky way, running her tongue along the lower side of her erection.

“Don’t act you don’t love it.”

Octavia gripped the wall, breathless.

“Y-yes…”

“Good girl.”

Octavia felt her skin burning with lust, her cock aching in anticipation. She knew Vinyl was riding this pony for all it was worth. She was about to say something else before she felt it –the warm, wet sensation of her friend’s mouth wrapped around her head.

Pure bliss.

Perhaps too much bliss.

In a sudden fit of animalistic desire, she pressed Vinyl’s head down on her cock, making her take the entire length in one go. She could hear her friend gagging, but she didn’t care anymore. No more waiting, no more teasing. She was going to have this now.

The DJ was caught off guard by Octavia’s reckless abandon, but couldn’t stop, even if she wanted to. There was something hypnotic about it – the smell, the taste, the feeling of helplessness as she struggled to breathe.

Powerlessness. She had rarely felt that in her life; now she was entirely at her friend’s mercy, unable to escape or resist, and it turned her on like nothing she had ever felt before. Her slit burned with anticipation, her panties quickly soaking themselves through.

Vinyl almost felt she was on the precipice of orgasm before noticed a shift as Octavia became more frantic, her moans becoming short and shrill.

“Oh buck!”

Octavia thrusted her hips, violent spasms rocking her body as she came, the force of her ejaculation shooting Vinyl across the room and knocking her into the front door.

The cellist hardly had time to bask in the afterglow before she realized what had happened.

“Vinyl!” She ran over to her friend lying there, eyes staring blankly, face covered in cum. “Speak to me!

Her friend gargled, but nothing else.

“Buck! What have I done! She’s probably got a concussion! What should I do!?”

She pulled out her phone and began to search the internet for how to treat a concussion when she noticed the time.

6:45

Octavia immediately looked to the kitchen clock which read a quarter to eight.

“Oh, yeah…daylight’s saving. I forgot about that.”

She went back to the search screen before she stopped and jumped into the air.

“It’s daylight savings! That means I’m not going to be late for class! Oh huzzah! I still even have time to get ready. This is great! Vinyl, did you realize…oh.”

Vinyl’s eye twitched, her leg convulsing.

“I should call 9-1-1! But, on the other hand, I really want first chair cello...”

~

Octavia stepped out of the kitchen, fully dressed, her hair down.

“Okay, Vinyl, I left you some crumpets on the counter should you want them. Is there anything else you need before I pop out?”

She looked over her friend laying near the door, legs propped up on pillows, still coated in cum.

“I know, I know, it’s uncomfortable, but I think you need to keep your legs elevated…or something. Now don’t you worry, I’m sure everything is going to be just fine.”

She glanced at the clock.

“Oh, but would you look at the time. I’m sorry to leave you like this. I promise I’ll make it up to you – somehow.”

With that, Octavia beat a hasty exit out the front door, racing down the dorm stairs and emerging into the cool, fall morning air.

She breathed deeply – the sun was just rising. In many ways, it was a new day. No longer would she be a passenger in life; those days were done. From now on, things would be different. They had to be different.

This was a new her – the real her. And she was determined to let herself loose on the world, regardless of the consequences.

As she trekked through the dew that lay thick upon the grass and the sun casted its brilliant light over her, she felt herself born again.

She was Octavia Melody.
