Dicksiplinary Measures

Thin slits of light pierced through the shuttered blinds. Pressed together just as thin, Principal Celestia's peach-painted lips tugged to a frown.

"Miss Dusk. Timely as always, I see." She knit her brows at the ditzy bluenette, dressed in a skirt and haltertop far too revealing for the school's dress code. She had been noticing such violations quite a lot lately, from far too many in her - literally - swelling student population.

"I'm not very timely though," Sonata burbled, tapping her chin as she gazed towards the clock. I'm fifteen minutes late."

"Yes," Celestia sighed. "You are."

"Then why did you say I'm early?"

She rubbed the bridge of her snout. This was going to be a long day.

"Sit down, Miss Dusk, and please, shut the door behind you."

Sure!" Beaming, Sonata skipped her way over to do just that. The broad bubbly curve of her butt bounced, cutie marks half-visible from that pink strip of cloth she called clothing. Clicking the door closed, she spun back around on her hoof and jiggld her way to the seat, barely constrained tits plapping together with far too much excess cleavage. Celestia herself had larger breasts, and she at least bothered to wear a shirt and jacket that covered her immodesty. Sonata, it seemed, had no such interest.

"Do you have any idea why you are here?" Celestia arched a brow, praying for an answer. She knew deep down whichever one she got was going to make her headache worse.

"Is it because I'm a super duper awesome top of my class student and you wanna give me a kiss for doing such hard work?"

The girl, to Celestia's mild horror, seemed genuine. Those wide fuschia eyes and bright smile, hands clasped eagerly together certainly suggested so. God, what did she ever do to deserve this?

"No. You're a straight C-student actually. With the exception of..." Celestia checked her papers. "Physical Exercise. B+. I suppose that's something."

"So then why am I here? I didn't do anything bad, did I?" Like a beaten puppy, Sonata's demeanor switched on a dime. Hands down on her lap, she stuck her lower lip in a drawn pout.

"Yes and maybe."

"Oh." Her shoulders slumped, ears splayed in defeat. "I'm sorry, Principal. What did I do wrong? Or, uhm. Maybe do wrong?"

"For one, that... 'outfit' you're wearing is not even remotely up to code. Frankly I'm not sure how you haven't been called into my office sooner, but I suppose a significant portion of my female student body of late has been doing the same. Which brings me onto the maybe."

Opening her desk, Celestia pulled out a phone. A phone that, judging by Sonata's reaction, she seemed to recognize.

"This is Rarity's device. A teacher took it from her while she was texting in the middle of class. Something, I'll note, that she hasn't done before until very recently. It is strange, given her past behavior. Stranger still what she was texting, and who she was texting it to."

"Y-yeah?" Sonata squirmed, like a worm on Celestia's hook. Fidgeting with the hem of her skirt, she kept her gaze away from anywhere but Celestia's. "And what's that?"

"Have you ever heard of sexting, Miss Dusk?"

"Maybe..."

"Well, there you go. If you're intelligent enough, I'm sure you can guess with whom specifically she was texting. I find it deeply troubling the sort of material that was shared, especially the photos, and it's helped open my eyes to a trend."

"Trend?"

"Oh yes." Celestia picked up the phone, turning it on to idly finger through it. She wasn't doing anything in particular, just exploring casually to provide a sense of confidence. The more uncomfortable Sonata became, the more likely she might spill the truth. "It's a trend I think you might have something to do with. Teen pregnancies are nothing wholly unexpected, but the frequency of them... has been very troubling."

She set the phone down with a click. "'Mommy Nata'."

A bead of sweat trickled down Sonata's forehead. Taking in a deep breath, she shuddered.

"I'm waiting."

It took a moment before Sonata managed to speak. When she did, her voice came out meek and cowed. "Can I be honest, Principal?"

Celestia gestured. "Please."

On another dime, Sonata transformed. Standing up so fast the chair slid away, she yanked up her skirt, and thwumped an arm-length log of tealish blue, equine fuckmeat onto the desk. A mixture of sweat and profusely dribbling pre stained Celestia's documents, soaked with salty, musky, milky residue.

"I really like turning girls into totes hot bimbo cumdumps. They always really love it! You wanna taste?"

Gluk gluk gluk gluk, schnrrrrrrt!

Oh god. What was she doing?

Celestia's head felt so fuzzy and numb. But her body, hnngh. She hadn't been touched this good since she was in her twenties, maybe ever. Sonata played her like a sexual flute, and she couldn't get enough.

Throwing her head up and down the towering length of Sonata's siren spire, bubbling spit frothed and boiled between the borderline perfect seal of her lips. Each bob down she sucked her cheeks in harder, pressed her pillows deeper, to leave a smearing ring of peachy pink behind on Mommy Nata's meatstick.

Throat bulging obscenely, snout buried in Sonata's lap to huff lungfuls of neuron-frying studmusk, Celestia groaned in orgasm. Waves of electric warmth rocketed up and down her slutty, cow-titted, fat-assed body, stripped to nothing but her panties. Sonata said she wanted to do something with them, so Celestia listened.

"Jeez, Principal! I knew that cougars like you were dick-deprived, but this?" Placing a hand over her pretty mouth, Sonata tittered. "I woulda like, totes cocked you sooner. Just wait til you see me in a cock ring! Little Nata gets soooo big and veiny, you're gonna fall in love with her."

Celestia was already in love. The myriad lipstick kissies smattering the expanse of Sonata's rod, nuts, taint, ass, and inner thighs proved that enough. She wanted to marry this thing and have its babies.

"Hfff, fuuuuck, Celly!" Reaching forward, Sonata looped her fingers through Celestia's hair, and tugged on them painfully. Celestia whined in response, another honeyed squirt of juice running lines down her thigh. "I'm gonna cum, cum, cum! Drink it all up so I can take a selfie with it!"

Sputtering, Celestia gagged on girthy cock and pints of foalbatter. Plenty spilled down her chin, exploded out onto her cheeks or snout or tits or glazed Mommy's crotch, but she knew Mommy Nata wouldn't mind. Mommy liked a big mess, because it meant her cocksleeve condom whores could lick it all up after she finished.

Pulling out, another volcano burst erupted from that hose and Celestia's spunksocket mouth. Most of it slapped onto Celestia's heaving, hanging knockers, or striped down her mascara-streaked face.

"Look up at me with those cute hearts in your eyes. Yeah yeah, like that! Now put your hands up and stick your fingers out, like you're giving me the V. Perfect! You are, like, such a good catch. Aria's gonna love getting you to eat her creampies out."

Repositioning herself, Sonata went to Celestia's side. Kneeling, mouth open and tongue out to show the bubbling mouthful of shemale siren spooge, she didn't dare move a muscle. Sonata beamed and stuck out her tongue, used her free hand to grab at Celestia's scalp, and snapped the photo.

"Gonna send this off to the girlies, hope you don't mind~ You'll get to meet them all super soon! Now stand the fuck up and bend over. I wanna turn your pussy into my glue swamp."

Not ordered to swallow, Celestia burbled 'Yes, Mommy' as best she could through the goopy, layered nut-tar mass. That sticky sperm-load would be staying right there until Mommy told her she could gulp. Celestia didn't mind, honestly. The heat and creamy taste only got better the longer it basted her tongue, numbing her tastebuds with the flavor of dickmare ballbrew.

Wiggling her hips, she hiked her tail. Bosom mashed and pillowed against the desk, flanks wobbling, she reached back to spread both her pink holes. Even if Sonata wouldn't fuck her ass yet, she knew the show would be appreciated.

Pole slathered in spunk and spit, Sonata slammed inside. Right through to her womb, Celestia gargled helplessly as fresh, painful tears sprang to her eyes. She gripped the corner for dear life as Sonata jackhammered without any warning or pickup, intent to turn Celestia's babymaker a whole new color.

Thunk! Thunk! Thunk! Thunk!

Papers, pens, and everything Celestia had on her desk flew or fell off. Her laptop crashed to the floor, something crunching inside. Rarity's phonescreen shattered. A photograph of Celestia and her sister did the same, antique heirloom picture frame chipping against the linoleum.

Celestia watched them through hazy eyes, and came with each broken thing she had. None of it mattered anymore.

"Mmmph. I'm close already! Wowie, you're tight. Don't worry, I'll fixx that soon, especially when you've got a litter of foals to push out~"

None of it mattered anymore.

Only Mommy Nata's dick in her brain.
