Two important instruments

Vinyl Scratch tapped her hoof on Octavia’s coffee table while Twilight paced about explaining her latest predicament. The white DJ was developing a tasty beat in her head as the princess of friendship rambled on.

“...and I need to sing a thirteen minute long aria or my princess-ship will be invalidated! It’s in a month! Can either of you help me?” The lavender alicorn pleaded. She watched as Octavia pondered for a moment, the grey musician was deep in thought.

“That is rather long isn’t it? But I don’t know why you’re so worried, don’t you and your friends sing ALL the time?” Octavia responded tersely. She’s seen Twilight sing countless times and take on endless challenges while doing so, she was completely baffled as to why she would come to them. Twilight’s reaction cleared up any confusion.

“I’ll be singing in front of Princess Celestia! It has to be perfect. Please you two have to know something to help? Some way to help me sing better or increase my stamina?” Twilight sputtered, causing her eye to twitch wildly. The volume was even enough to make Vinyl take notice despite her headphones. Sauntering over to Octavia, the blue maned DJ whispered something in her roommate’s ear.

“Hrmm? What is it Vinyl? Oh really...” a lusty smirk spread across Octavia’s face as she listened to Vinyl’s plan “I do believe that will work.”

Twilight listened intently as the two stopped whispering and Octavia stepped forward and cleared her throat.

“It seems we can help you with your problem, we even have the appropriate instruments for the job. Vinyl and I may be a little hard on you, but we are certain you can take it all in. But you must do everything we say. To the letter.” The black maned Octavia told Twilight. The purple princess nodded happily in agreement.

“Very well, Vinyl if you would be so kind?”

Vinyl nodded and sat down in her retro-funk easy chair . A purple and yellow striped monstrosity from her college days. She motioned Twilight to stand in front of her. As Twilight stepped into place Vinyl’s horn flashed and there between the mares legs was an enormous dick. Even flaccid Twilight could see it was over a foot long. Nervously she looked to Octavia, only to find that the grey pony was sporting a huge penis of her own!

“Oh, I see very hard.” Twilight blushed as she eyed the towers of cock offered before her. “But will this actually help? I won’t say no either way. Starswirl knows I could use the stress relief...”

“Trust us, by months end you’ll be able to sing an entire opera by yourself.” Octavia winked.

Taking off her headphones Vinyl grinned and pointed to her cock, silently commanding the Princess to suck her off. Twilight eagerly complied, lifting the hardening member to her mouth. The smell of floral bath soap mixed with the heady masculine musk of Vinyl’s cock made Twilight’s head swim pleasantly. She began lapping around the rapidly swelling flare with gusto before shoving the head into her throat.

“Ah ah ah.” Octavia chided the greedy mare whispering in Twilight’s lavender ear. “You must sing the aria while you blow her.”

Twilight popped the cock out of her mouth with a loud wet sound and began to protest. After all how could she sing while she had one and a half foot penis in her mouth? But Octavia only shoved her head back down on Vinyl’s enormous meat tube.

“Sing.”

And as commanded Twilight began to sing the ‘Princess Aria’, though with the cock in her mouth the only thing anypony could hear was the muffled rhythm in between gasps of breath. Vinyl listened carefully to Twilight’s song as she struggled with the large endowment. The poor princess was decent as far as blowjobs were concerned but Vinyl could tell her breathing technique was awful and the vibrations through Viny’s dick told her that Twilight was off key at several points.

Vinyl shook her head at Octavia as Twilight came up for gasping for air. The DJ pony’s cock throbbed and ached for release but obviously Twilight needed to work on a lot more than they thought. She hadn’t even finished half her song, let alone get the blue maned pony off.

“I believe we have identified your problem, you’re breathing technique is terrible and you’re not using your diaphragm.”Octavia poked Twilight under the ribs to emphasize her point.

“I’m sorry...” Twilight apologized and wiped some precum and drool from her muzzle. Octavia gave a reassuring smile and told the purple alicorn to do it again. This time she used her hooves to help Twilight match the rhythm of her aria and her fellatio. When She was satisfied Twilight was doing well, Octavia positioned herself behind the taller mare.

“Good, very good. Remember the soft points of the song where you can get a bit of breath.” Octavia commended the princess’s second attempt. Licking her lips, Octavia dived muzzle first into Twilight’s muff lapping up every inch of her magical marehood. Twilight squealed with delight. The classical pony’s tongue play was fabulous sending mini orgasams through her body giving her just enough keep her on the edge and enjoy herself but not enough to make the studious pony lose focus.

Vinyl was impressed as well, the techno loving pony was developing a new appreciation for classical music. The vibrations Twilight sent through her cock this time made her understand Octavia’s love for the genre. She was almost there and halfway through the song by now too. She motioned to her partner who nodded in agreement and stopped her ministrations on Twilight.

“You’re still not using your diaphragm.” Octavia smiled mischievously, her muzzle dipping with Twilight’s love juice. She stood up and positioned herself properly before shoving her own nearly two foot long member into her.

Twilight screamed in ecstasy as the rod hit every pleasure spot she had. Octavia’s expert cunnilingus had already brought her to the edge and now the sudden fullness tipped her over. She somehow kept her wits about her instead of collapsing into a orgasmic pile on the floor. She was nearly finished her song and Vinyl was getting close to cumming too. After all she didn’t want to disappoint her two new teachers...or Celestia.

Matching the rhythm of Twilights song Octavia pounded the singing mare happily, she was quickly catching up to both of her two lovers, Twilight’s pussy greedily devouring the mountain of meat. Octavia was never a quick shot but Twilight’s heavenly marehood was far better than any she had before and she tried hard as she could to not cum right away. She slapped Twilight’s cutie mark harshly whenever she missed a note.

As the three neared the songs crescendo and end Vinyl let out a musical moan as she finally came. Gallons upon gallons of hot delicious seed poured down Twilight’s throat making her pussy clenched even tighter as her stomach bulged from the exorbitant amount of cum.

The sudden tightening broke Octavia’s concentration making her fuck Twilight even faster forcing the poor pony to cum again and again as both her womb and throat were stuffed to the brim. Finally the brave princess passed out. Her pussy being pummelled as Octavia finally came herself. Twilight’s already distended belly expanded out more as ropes of hot wonderful cum invaded every inch of her welcoming womb. Pulling out, both Octavia and Vinyl covered her from head to hoof in a blanket of cum.

“You were right Twilight,” Octavia panted “we really do need to work on your stamina. But don’t worry, we’ll give you lots of practice with our instruments.”

One month later

Twilight bowed as she finished her Aria.
The other assembled princesses clapped their hooves frantically, blown away by Twilight’s skill.

“Twilight, what an amazing performance!” Celestia congratulated her faithful pupil. The white alicorn’s mane flowed elegantly but her tail twitched with happiness and pride.

“Very commendable Princess Twilight, it took Celestia three tries before she mastered in as many centuries.” Luna teased. The midnight mare dodged daggers from her elder sisters eyes.

Cadence just scooped up her little sister-in-law in a big happy hug. “How did you do it Twilly? Even I had trouble but you were perfect!”

“I had some help from two very good teachers. They’re very good at it too.” Twilight blushed as she scuffed the stage floor with her hoof. Memories of the past month rushing back.

“Hrmm, perhaps I should take some lessons as well.” Celestia mused Luna and Cadence nodded in agreement, they echoed the sun pony’s sentiment.

“Well I have another lesson today and I know that they’d love to have you join us.” Twilight offered.
