Jet Stream groaned as he entered his elevator. With a small yawn and a roll of his neck, he popped several of the ligaments that had been plaguing him on his trip home from his head office.

It had been a long day.

Too long.

Normally, he didn’t mind working. He loved the hustle and bustle of his company, especially when he could find a few moments to extricate himself from the corporate side of running such a massive enterprise. Being able to leave the frustrating strategic and governance meetings behind, being able to sneak down to the engineering floor and dive into the thought processes of some of Equestria’s brightest young minds as they designed the engineering wonders of the future… that was his true passion.

There had been no chance of doing that today, however.

Today was his birthday.

The big four-oh.

40.

That morning he had almost wanted to just call in sick. Looking across at himself in the mirror after a quick shower and shave, having affixed his customary necktie, he’d dreaded what the rest of the day would be like. He’d managed to resist, going into work as his responsibilities demanded.

Jet scratched his mane, looking at the elevator floor lights blink and increase as he thought back to the long day that had just passed.

It started almost immediately upon his arrival. The security guards making sure to wish him a happy birthday and provide him with a card signed by the overnight security crew. Then as he’d entered his corporate suite, the secretaries and administrative staff had given him a small gift - a little desktop clock.

He’d tried to refuse each and every one - there was an element of guilt: he earned more than all of those staff combined, they shouldn’t be getting him gifts… but the main reason that he hated getting birthday gifts was just how lonely it made him feel.

These people - his staff… they really loved him. Really wanted to make him feel happy and respected on his birthday. Any sensible pony would take this in stride, take it for the true gift of love that it was. But Jet was wiser than that.

He knew what he had traded in exchange for that love, for the hearts of his employees.

His family.

Briefly, his mind flashed to a certain blue pegasus, to the cold wintry days they’d shared together back in their university days.

Blinking, he shook his head, trying to dispell the painful memories - focusing instead on the whirring smoothness of the elevator motor as it lifted him to his penthouse apartment.

At least the junior staff’s affections felt real. Going up the chain of seniority at EquestriAero, with the exception of a few choice senior staff, brought with it the type of cloying sycophantry that could drive a stallion mad. Middle managers wanted to score valuable points with him, senior managers wanted to set themselves up for that next promotion or pay increase. Vendors and consultants all wanted to ensure that they would remain at the top of the list for the next big project.

And so, his whole day had consisted of meeting after meeting. Hoofshake after hoofshake. Strained smiles and forced laughs.

If only they had known how much he detested it all. The fake love was far worse than the real love… which in turn was a far cry from the familial love he truly wanted.

One of his few respites had been when Diamond Gavel had popped in partway through the morning. He’d looked up from his desk, pleading with his eyes at her - begging her not to attempt to wish him a happy birthday, not to fall into that same tired trap of giving him some trinket or card and forcing him to go through the same annoying strains.

“Damn boss, you really do look like an old fogey now.” Diamond had simpy stated deadpan. “Hell, you even smell old.”

Jet had burst out laughing, the little insult exactly what he needed - a cutting little comment to make him feel normal, to give him a dose of reality - a sense that he wasn’t crazy, that it was OK to feel miserable on his birthday… away from his family.

“Thanks, Diamond.” He’d replied, leaning back in his chair. “I needed that.”

Diamond smiled warmly. “Thought so, just wanted to say - I’ve taken care of Apogee’s return from your wife’s place. You should expect her back shortly.”

Jet had nodded, appreciatively. His teenage filly had gone to his ex-wife’s junkyard for the week, part of him and Apogee’s plan to re-integrate the filly into the surly scrapyard mechanic’s life. He’d considered reaching out himself to see about getting Apogee back for the weekend… but it was probably better that Diamond had taken on the task herself - he’d probably wanted to do it out of loneliness, out of a desperate desire to reconnect during this day of weakness.

It would almost certainly have gone badly.

“No problem, boss.” Diamond grinned. “She’ll be back sooner than you think. But if you get lonely tonight…” Diamond had pulled out a silver flask wrapped in a tight red ribbon, emblazoned with the EquestriAero watermark.

Jet took the proferred flask from her magical field with his wing, looking at the thoughtful, well-crafted flask. He could tell from the weight that it was already filled.

“Encouraging me to give in to vice, Diamond?” Jet had grinned at her, raising an eyebrow. “THat’s not like you.”

“Hey Boss, I figure it’s your birthday…” She’d winked at him with an unusual look. “I can help you indulge in your bad habits once a year, at least.”

…

Jet slumped back against the elevator wall. What he wouldn’t give to see his daughter now.

She was the one beacon of light in his life. The one thing he’d managed to do right. The one spark of love that he had managed to kindle in this world.

Jet shook his head softly at himself. Just how had he gone so wrong? The company, the success, the engineering… it was all supposed to have been a means to an end. He’d always seen it as part of that idyllic vision - the accomplishments that he’d need to pull off in order to win the heart of Delta Vee.

She’d always been so incredibly smart, talented, gifted.

In his own mind the only way to keep a mare like that, to get a brilliant engineer like her to stick around with a dope like him and make a family… was to dream big… and accomplish bigger.

How had he managed to end up with all the money, all the success, the glory, the science… and none of the love? Even his daughter wouldn’t be with him on this birthday night…

He’d be alone, celebrating his 40th as a mere shade of what he’d hoped to be. As a lonely millionaire in a luxury apartment. Getting older and living yet another day as a failed father, husband… a failed stallion.

He could use that drink now.

Jet reached into his saddlebag, plucking out the silver flask. It was the only gift he’d chosen to take back with him from the office. With a quick flick of his hoof, he undid the ribbon and untwisted the cap.

He took a deep swig.

Immediately he noticed something was… off.

The taste was definitely similar to his favorite scotch whiskey… but there was something else mixed in there, some familiar undertone… but he couldn’t quite place his tongue on the taste. In any case, the drink began to fill him with warmth, heat. Even more so than he would expect from such a fine scotch.

He took another swig.

Even more warmth pulsed through him, radiating out from his gut. The hackles on his fur began to rise. He could feel his nostrils stiffening, widening. His muscles felt plump, bulgy.

And his groin began to ache…

Jet clenched his free hoof before taking another swig. Hoping that the sensation would halt the sudden urge to let his junk slide out of its sheath and begin to dangle free in the elevator.

‘Just what was in this drink?’ Jet arched an eyebrow. ‘More than just booze …’

Jet shrugged and polished off the last of the flask, just as the elevator dinged, having finally reached the top floor of the apartment building. Fumbling for his keys, Jet stepped out of the elevator, walking the short distance to the door only a few footsteps away. The extra steps caused his plumping bits to bounce more energetically than they might usually…

And he felt himself slip from his sheath, his brown cockhead beginning to poke out into the air and fall out.

He grimaced to himself as he unlocked the door and began to turn the handle. At least one part of himself didn’t feel like it was forty years old. Hay, he could at least hoof himself off before passing out and putting this miserable, lonely milestone of his life behind him…

The door creaked open.

And then he saw it.

“Well well… what do we have here?”

Jet looked down with wonder at the teenage filly face-down ass up in the entrance hallway. His daughter.

Apogee.

The shock of seeing her, when he had expected her to be at Delta Vee’s junkyard, quickly wore off. All the thoughts of loneliness and having to hoof himself off that evening vanished like a raincloud kicked by a pegasus… leaving a bright, sunny sky behind.

A grin came across his face as his eyes drank in the sight before him, slowly tracing over every curve, every detail of his little filly’s beautiful body.

The filly was wearing a set of blinders, and a red ball gag.

He could see from the trickle of drool coming out of her mouth that she’d only recently put the gag on - she hadn’t had enough time to have her throat and mouth dry out.

In her ears were a set of little plugs, blocking out any sounds that the filly might have been able to hear. All she would be able to sense in this state were smells and touch - and what she was feeling from those two sensory organs must have been quite exciting.

Wrapped all around her forearms and culminating in a tight loop around her upper back was an exquisite, red ribbon. The way in which it had been tied kept the poor little filly’s arms locked behind her back - bound more tightly than if she had been hoofcuffed by an officer of the law.

This kept her head and shoulders pressed against the hardwood floor of the apartment’s front hallway. Only her rear hooves were making contact with the ground… and she was currently spread… braced like a hoofball lineman in a wide stance that, in conjunction with her raised, flagging tail, left nothing to Jet’s imagination.

Below that bobbing, cute, ball of blue gree tail hairs, beneath the cutely wiggling yellow dock… he could see his daughter’s tight little tailhole. She’d always had a smaller ponut, a tightly clenched bud of plumpness… the way the wrinkles revealed the subtlest shade of pink within always excited him, reminding him of just how hot and tight the filly’s forbidden backdoor really was.

Speaking of hot.

A small waft of steamy heat brought his eyes further down, sliding over the crevice in between her adorably cute, freckled, pert, teenage buttocks.

The darker yellow swell of her tight little fillyhood immediately revealed just how turned on his daughter already was. Her engorged labia were twitching and squeezing against the already-flashing pink inner lips of her dripping cunt. He could already see hints of the boiling interior hinted at deep into her tight cleft, little peeks of that velvet tunnel betraying itself to him as she winked in and out.

And what powerful winks those were!

Apogee’s little clitoris was already swollen to nearly the size of an equestrian bit, stiffly protruding into the cool air - hot drips of steaming nectar slipping off the end of the fleshy bud with each convulsion clench of her nethers.

Each quiver made her tighten her ass, thrusting herself ever so higher up into the air, revealing and preparing herself for a stallion - begging to be mounted… sending her tight, teenaged crotchteats jiggling after each wink.

Only then did he notice a small tag hanging off her left knee - a talisman with her smiling face and her sloppy handwriting: Happy Birthday Dad!

The whole sight was breathtaking.

“Now now now, honey.” Jet clucked to himself as he approached his daughter, slinking off his saddlebags as he did so. “Just how did you get yourself in this predicament on your own, hmmm?”

He chuckled to himself, even as his heart began to race with excitement. Each breath of air was filled with that lovely, familiar scent of his most precious pony. The cinnamon spice that she’d sported ever since changing shampoos as a grade-school filly, that let him know she was near… now mixed with the rich, sultry, wafting musk of wet cunt that told him there was a mare looking to be bred.

The confusing contrast never failed to turn him on. He felt his cock slip from his sheath, quickly dangling down toward the floor, as it began to fill and thicken with the blood from his pounding heart.

“You couldn’t have done this all by yourself.” He clicked his tongue. With a glance, he looked up at the second story of his two-story, open-concept apartment, toward his daughter’s room. He wasn’t sure, but as his eyes flashed over the dark doorway, he could swear he saw the door jerk slightly and a shadowy figure take a step back into the shadows, watching.

Daisy? Diamond?

He grinned, unsure just who was there. But for some reason, he wasn’t feeling particularly cautious. That fire in his belly from the whiskey was quickly heating him up, making him feel bold. Confident. Rugged.

His stiffening cock was quickly becoming almost painfully erect. Filling with blood so rapidly that it slapped against the underside of his belly.

He snorted, clearing his throat and taking in a fresh breath of his daughter’s aroma. Usually, he needed a bit of warm-up to get so hard… but his cock seemed ready for action… his balls were already starting to hang and swing, implying they too, were ready.

And so was he.

He felt his oats, his cockiness already beginning to swim in his head. He was a big strong, alpha stallion after all. His muscles were taut, his jaw was sharp… and his cock was heavy. He didn’t care if somepony would be watching him rut his daughter - let them!

He’d give them such a show that if they ran to the papers about it, the tabloids would be stuffed for weeks with the details. He couldn’t care less!

“Do you want it that bad, honey?” Jet growled trotting up to his little girl, still mumbling muffled grunts through her gag.

Jet realized then, that she couldn’t respond to him. She couldn’t hear him. Couldn’t see him.

Perhaps she could sense his hooffalls through the ground - she must know somepony was near her. But that was all. The only thing the filly could sense was touch… smell. The primitive, ancient senses.

Jet grinned to himself, deciding at that moment he would take his time enjoying his little birthday surprise.

Carefully, he extended one feather, a long primary, from his right wing.

With the deftest of touches, he brought it to his daughter’s cheek. He let the light tip kiss her skin, dancing on the rosy face more delicately than a snowflake in a gust of wind.

As soon as it touched, Apogee stiffened, her muscles going taut as she realized that somepony was there with her, touching her, tickling her.

Jet slid his feather down the nape of her neck, making her quiver and extend her head in the same direction as the toying touch… before he slid the feather down his daughter’s spine. As the feather traced over that sensitive spot between her shoulderblades - the center of her wings, a muffled squeal escaped her ball gag.

Her wings strained and pulled against the red ribbon, stretching the fabric with the powerful pulse of a pegasus trying to stretch her wings to their full extension.

Jet laughed at her struggle, at the wagging fury of her tail and the wiggle of her freckled bottom.

He continued.

The feather made its way to her glutes, drawing lazy circles around the sweaty pegasus filly’s cutie mark in random, erratic patterns. She was shuddering now, taking gasping breaths behind the constraining, red ballgag. Jet wasn’t sure if she was laughing or groaning - tickled or tormented.

Al he cared was that his filly was dripping.

After a particularly, wet shudder, one which sent a sprinkle of fillycum spattering to the floor below, Jet made his move… He slid the teasing feather around to her backside, her plot… the lightest kiss of deather over her dock and tailhole sent an adorable shiver through her body.

Jet bared his teeth - a sharp, masculine grin. He could feel the throb of his horsecock as it became stiffer and stiffer. His body was already urging him to stop playing with his food - to take the girl now… and hard. A drip of hot pre-ejaculate fell from his massive, 17-inch staff.

But he resisted.

He brought the end of the feather to his daughter’s outstretched clitoris, tracing the outline of her spread labia on his way there.

Immediately, Apogee exploded.

“Mmmgg! Mnng! Mmmfh!” A series of desperate, choking grunts escaped her mouth before a powerful convulsion roiled down her body, causing her to shake her torso like a wet dog trying to dry itself, though it did little to free her from her ribbon-constraints. The shockwave culminated at her pussy… sending the desperate organ into a frenzy of activity, jumping and winking away from the feather which had just teased it.

In out. In out.

Her lips parted and slammed shut in rapid succession. Then a hot, steaming splatter of filly-nectar shot out, a sticky, pungent squirt that soaked the floor.

“Good girl…” Jet cooed, though he knew she couldn’t hear his encouragement.

Quickly, he withdrew his feather, placing his left hoof on the small of her back in a soothing petting motion… and taking his right hoof and grinding it skillfully into her winking teenage pussy.

Hot.

He could feel the burning, wet, raw heat of his daughter’s fillyhood against the soft frog of his underhoof. She was badly worked up - as though her ongoing orgasm was but a meager, insufficient relief valve to her desperate need.

He coaxed her further, grinding his hoof deeper into her as he did so, letting her ride out the end of her first orgasm against his hoof, soaking him as her convulsions slowed and subsided.

Jet chuckled to himself, beginning to work his two hooves in small massaging circles… one comfortingly petting his daughter’s back… the other exploring her leaking teenage folds… pulling itself over her quivering tailhole… slipping under and in between her legs to tweak her diminutive and erect nipples.

“You must be going crazy, honey.” Jet grinned again. “All this touch, all this pleasure… all while you’re in the dark.”

He slid his hoof to the clit of Apogee’s slit again, skilfully using the edge of his hoof to part her fattened folds and directly massage her clit, evoking another groaning shudder from the drooling mare.

“Do you want to know who’s touching you, honey?” Jet cooed, sliding his other hoof up his daughter’s spine, over the soft velvet of the constraining ribbon. “Do you want me to unwrap you? Or are you so horny that you don’t even care?” Jet bit his lip and pressed his hoof against his daughter’s asshole, stretching it open as he played with her taboo little pucker.

An idea entered his head, and he straightened his back, snorting slightly, squeezing his muscles to let his powerful chest fill, He might not be able to reveal himself to Apogee with sight or sound… and she might not be able to tell who he was just by touch…

But she could smell, him.

Jet released his little filly, a weak mewl accompanying him as he ceased his teasing touches. With bold steps, he walked to the front of his daughter and turned sideways, revealing to that hidden, suspected voyeur his side profile for the first time… and thereby his bobbing, engorged length.

A gasp escaped that room, drawing a bemused glance from Jet.

‘Let them look.’ He flexed his pelvic muscles proudly, bringing his huge, leg-thick cock taut against his belly… causing the wet, plate-sized flare to slap against his belly button. ‘If it’s Diz or Diamond they’ve seen it before… and if it isn’t..’ He glanced down at his daughter’s blindfolded, drooling face. He had no problem throwing caution to the wind - especially when he felt this… fire… burning inside him. ‘I don’t give a buck what they see…’

He carefully took hold of his huge, dripping cock with his left forehoof, positioning the arching curve of a foot and a half of dripping stallionflesh just in front of Apogee’s adorable, freckled snout.

He giggled to himself as her nose twitched, sniffing. Then her nostrils flared, gasping in deep, breathy inhalations of his musky, steaming stallionfumes… of the pheromone-laden musk dripping off his cockslit.

She could smell him. Him. His maleness. His musk. She was squirming in her restraints, grunting and panting. He could see her tongue playing at the ball gag, trying to free itself so that it could take a lick of that dripping flare just in front of her. She was snuffling now, big sniffing draws of her lungs… like she was trying to drink the rich, thick odor out of the steaming air itself.

She knew it was him. Knew the state he was in. Knew what that meant for her. For her little body. And she wanted him.

Jet felt himself swell with desire, lust. There was nothing sexier than a little filly who adored him, loved him, lusted after him so much that his mere smell made her wet. Nothing more validating to a big, strong, feral stallion like him.

He slid his cock forward, booping her in her nose.

She jerked back at first, surprised by the sudden contact against such a sensitive part of her body… before she realized just what it was that had touched her.

Immediately she began to grind her nostrils, her snout, her muzzle against his dome-shaped, drooling cockend.

Jet moaned with pleasure, deciding to simply hold himself against his daughter’s plaintive, thrashing ways. The feel of that filly’s wet nose sliding over his sensitive glans was exquisite, intense.

An involuntary squeeze of his pelvic floor muscles from a particularly needy muzzle thrust sent his cock jerking upward… and shooting out a thick dollop of stallion pre-ejaculate.

The wad splattered across his daughter’s left nostril, making her cough and wheeze at the sudden splash of pure, testosterone-laden essence exploding into her olfactory sensor.

She started to cough and wheeze, groaning and drooling around her ballgag as the potent pre-cum saturated her, overwhelming her.

Jet looked down with concern - she was already a drooling mess… now she seemed to almost be choking on him. He drew back, smearing the sticky strand of clear honey against his daughter’s forehead.

With concern, Jet felt that alpha-intensity fade, that feral maleness, sink back, replaced by a loving and worried concern for his daughter. “Are you OK, hon-”

Jet cut his own question off as Apogee began to shiver and convulse again, a tremor of quivering, bunching muscles racing down from her neck, right through to her buttocks as it did… a muffled scream followed, the filly began to grind her sweat-soaked brow in wanton desire against the slippery hardwood floor, her ass up in the air and bucking, humping against an invisible stallion.

She was cumming.

Just from his smell.

A heavy choking sneeze followed a moment later - Apogee’s poor little nose expelling the fluid which had overwhelmed her. The splatter of her sneeze was followed half a beat later by the splashing slosh of clear, hot nectar shooting out of her fillycunt.

*SPLOSH* *SPLOSH* *SPLOSH*

Three heavy jets of cum splattered to the floor, leaving a spreading puddle of rich, musky filly juices. Jet had never seen her cum so hard… not with nopony even touching her.

His mouth dropped open in wonder.

But his hooves started to move of their own accord… bringing him back behind her once again.. To that ancient spot… the place just behind a ready and willing mare… moments before the two ponies would become one… joining in that ancient, biological dance… one that didn’t care for rationality, law, incest or taboo… that only cared for dripping, pure, lust.

Jet grunted, feeling the swing of his oats beneath him… the heavy, aching fullness of his stallionhood. The warm wetness around his hooves from the pooling fillycum on the floor.

How could he be so cruel as to have tortured his poor little filly so? All she wanted was to give herself to him - and he’d made her cum all over the floor, treating her like a toy. He snorted, drinking in the air of his filly’s plot. And here he’d gone tickling and massaging her, teasing and soaking her… instead of doing his duty.

He took another whiff of that pungent fillycunt, which hung in the air like a fog. Gods Apogee smelled good when she was in heat.

With an instinctive jerk, he shoved his snorting nose right into his teenage daughter’s plot, cramming his nose against that delicate smooth patch of flesh between her cunt and tailhole. His nostrils flared and inhaled, drinking in the freshest, most potent source of aphrodisia.

Dimly, he heard a muffled groan. But Apogee’s whining mewl only served to heighten his thirst.

He buried his face deeper, mashing his nostrils against her ponut and catching a whiff of her earthy, natural smell… all so that he could open his mouth and slide his tongue into his filly’s tight, twisting pink lips.

She quivered and shook, her butt initially pulling away from the sensation of being eaten out - before pushing back with gusto, grinding her teenage pussy onto her father’s tongue.

She had the most delectable taste, like honey mixed with spices… but the thing that Jet loved the most about his daughter’s moist cunny was just how writhing and muscular it was. Those pink labia swirled and grasped at his tongue, drawing more of him into her, like a lover pulling in her stud in a deep french kiss… only she wasn’t doing it with her mouth… but with her vaginal muscles.

Jet groaned, a squirt of fillycum spattering off the underside of his chin. He hated when he missed drinking in her clear, fresh nectar. He dipped his mouth down, pulling his tongue with difficulty out of her tight hole, wrapping his lips around her fillyclit instead.

Suckling in, he drew the erect nub of fillyflesh into his mouth, battering it with his tongue in rapid, vibrato lashings.

“Mmm! Mm! M! M!” Plaintive squeaks filled the air as Apogee’s bud began to quiver outward in rapid succession, bumping against his tongue on its own as it strained in pulses to wink into her tormentor’s muzzle.

She was cumming. Again.

Jet hummed with satisfaction, letting the vibration from his belly rumble tickle through his mouth and into his daughter’s spasming bits. He caught a heavy thump to his nose, a lashing whip of her tail, an inadvertent buck of one of her rear legs. His little filly did have a tendency to lash out when she had a particularly strong orgasm. It was always with the little bumps and bruises…

A moment later his mouth was flooded with her mare-essence… three heavy squirts of sticky juice filled his muzzle faster than he could swallow it, pouring out of the sides of his mouth as he guzzled his daughter’s orgasmic nectar.

It was like a rush of hot, boiling catalyst… the perfect chemical stimulant to add to whatever brew had been filling him with such heat, kicking him into a whole new level of need. He could feel his eyes shifting, hardening… pupils shifting to the lightest outline of a heart, as sparkles filled his vision.

His muscles tensed, bulging under his fur, expanding, pumping. His body was pulling every hidden store of testosterone and stallion-magic to infuse his body, his being. His jaw felt stronger, tighter… his chest bigger, taller… He stamped his left forehoof. His nostrils felt thick and full, flaring and snorting.

‘G-gods… I’m so fucking… horny!’ Jet grunted. He never felt like this… not even in his trysts with supermaredels or famous actresses. The sight of his daughter, his purest love… about to be defiled, dominated, destroyed by his lust… it brought something out in him. ‘I’m… so…. Hard!’

The coursing energy surged through the base of his belly, rushing down his cock in heavy, pulsing throbs. He felt his balls swell and sink, looking like a pair of softballs stored in a sock. A wet *THWAP* filled the air as his cockhead extended another two inches, jerking up and slapping him just above his belly button, impacting with a wet strike that smeared his pre-ejaculate into his fur.

His cock felt huge. It was huge.

Every bit of it ached - every bump and ridge, every vein, every ring, and ridge. It was like the spongy, blood-engorged cavernosa had been so pumped full that it had become as solid as concrete, straining against the dark layer of skin painfully… stretching his girth wider than his body had ever been before.

His cockhead was semi-flared, tilting up away from the main body of the shaft at that angle it kinked to whenever he would cum, designed by evolution to lodge itself in a mare’s womb… the knobby ridges on his flare’s edge were already partly expanded, the thick spine of his cock straining outward… giving his whole penis a menacing, monstrous appearance.

What was he doing!? He snorted, swallowing the last of his filly’s cum and clearing his throat. He’d once again put his poor little girl through all sorts of unnecessary additional suffering, all for his own selfish desires. She wanted, no… needed to be bred. And he needed to breed her.

He opened his mouth to soothe her, reassure her.

“N-n-neeeeeighh!” A strange, feral whinny gushed from his lips instead. He clacked his teeth together, tensing his newfound muscles and preparing to mount his small, teenage filly.

With a thumping clatter, he clambered over her upstretched ass, slamming his heavy hooves down on either side of her shoulders. He almost slipped, bringing his heavy cock bobbing down to slap off the side of her ass, before he was able to extend his wings to steady himself.

‘C-condom? P-protection?’ His mind raced, trying to assert itself as a final warning. But something else had grown within him. A culmination of all those hormones, all that magic, all that need boiling through his system. His mind was fading into the background, a quiet voice against the shouting yell that was his biology.

There was a mare that needed to be rutted.

He knickered, swinging his hips into position and humping with abandon. The wild, stabbing pokes slammed into his daughter’s thighs, before sliding off and slipping under her teats, riding up the inside of her belly up to the bottom of the little filly’s ribcage… leaving a slick, dripping trail of pre-ejaculate in its wake.

He snorted with annoyance, his body unhappy that it hadn’t immediately buried his long, hard length into the hot, willing snatch under him. Apogee groaned, wriggling back and forth against her father’s bobbing cock, doing her best to push her body up against his chest, mashing the big red bow into his ribcage.

Jet pulled back, clenching his muscles to jerk his blood-heavy cock to a higher angle as he did so, a better alignment to try to thrust it into his mare’s body.

He drove forward again.

This time his flare mashed up against Apogee’s taint, that smooth patch of skin between pussy and tailhole, before sliding up and wedging itself against her tight little pucker - the dome of his fat cockhead spreading her ponut ever so slightly.

“MMmmrggh!!!” A squeal of protest came from under him, Apogee jerking away at first, then relaxing. She hadn’t expected her daddy to want to fuck her there. Not at first, anyway.

Jet clenched his teeth. That inviting kiss of the ringed pucker was tantalizing, tight, warm. He knew with another buck he could drive himself into her sweet little asshole - fuck her thoroughly like the bad little filly she was. But that wasn’t what he wanted. Not yet.

He needed to unload in her womb.

With the last vestige of restraint, Jet slid back ever so slightly, drawing his cock down and away from the yellow tailhole, over the slick taint… grinding it into that tight, winking fillyhood.

Both ponies immediately let out constrained grunts as their hot bits connected in a wet, boiling kiss.

Jet could feel his dome-tip mash up against her tight lips, spreading them ever so slightly as they strained to part, the pink inner labia stretching wider and wider, jamming against the plump, engorged labia majora… before his width was finally barred from entering its promised land by the sheer tightness of the filly’s opening.

Jet stomped his hoof with feral frustration, huffing out a breath of air before thrusting.

His cock mashed against his daughter’s vagina, still failing to enter her, bending the kink in his penis dangerously with the force of his bodyweight. If his cock had been less thick, less massive… the bend might have proven disastrous.

Apogee squealed under him, a soft scream coming through her ballgag as her body strained and failed to admit the huge, girthy intruder. But she didn’t flinch away, didn’t run. She wanted this as bad as he did.

Jet felt his daughter’s hooves plant themselves underneath him, steadying themselves so that she could thrust back into him, twisting and angling her upstretched ass to slowly work more of his huge, girthy cock into herself.

Millimeter by millimeter, Apogee’s straining lips slipped wider and wider, spreading more and more as they approached the wide, knobby, coronal ridge of his flare… until… agonizingly… they slid over the edge.

*POP*

Instantly, her lips engulfed his fat cock, sliding in to snugly embrace his shaft as he sank six inches of his penis into her merely from the tension that had been in his cock.

His glans were wrapped in a swirling, muscular, velvet slick wall of fillycunt. The folds in her vaginal depths squished and squeezed against his every contour, embracing him as if his cock and her pussy were long lost lovers.

He was inside her.

The little filly he had raised, almost on his own. He’d changed her diapers, told her bedtime stories, bounced her on his knee… stayed up late watching movies with her… helped her do her homework, hugged her when she was feeling down… received father’s day arts and crafts gifts from her. His darling. His angel. His honey.

And how he was fucking her.
The thrill of taboo always made him quiver with excitement.

Instinctively, he began to pump. He thrust his massive pole deeper into her body, the thick head cavitating her tender walls as it plumbed deeper into her, spreading her, straining her.

“Mmmgrgg! Mmmrgh!” Apogee was grunt in pleasure.

Short, powerful strokes that pulled his cock in and out, each time driving deeper into the filly’s tight little body… a noticeable bulge in her belly as inch after inch methodically made its way into her.

She was so bucking tight!

Jet hooked his hooves onto her upper shoulders, using them as leverage to bring more of his powerful hindlegs with each subsequent thrust, achingly grinding more of his stiff cock into her well-stretched lips.

Quickly, his medial ring bumped against Apogee, jamming the final 8 inches of his dark cockflesh outside of her body. His stallionhood started to get almost terrifyingly thick below the ring, his girth quickly growing to an enormous, hoof-sized trunk at the base of his long, proud dick.

“Hnnngg! MMhmmm!” Apogee’s moan of pained pleasure was wrenched from behind the ballgag as the fat ring slowly, agonizingly, stretched her once again before popping into her lithe body.

“Urggghh!” Jet grunted in pleasure - it felt like his cock was being compressed, crushed down by his daughter’s tightness - despite her enthusiasm at taking her daddy’s dick, she was still a diminutive filly… her body could barely handle him.

He had been slowly bringing their hips closer together - at first separated by his full 19-inch length… now creeping closer and closer, his rear hooves approaching hers, getting closer each time he stuffed more of himself into Apogee… driving a bit deeper with each short-stroke thrust… withdrawing a bit less on each pullback.

Her body was so small, so light. It felt like he was wearing a sleeve. She was so small… so light... with his cock spearing through her, he felt like he could hoist her whole body up by his dick alone.

“Mmmnf! MMMF!: Apogee’s groans were getting louder now, desperate. She was reaching the limit of what her tight teenage fillyhood could take. The increasing girth was stuffing itself obscenely into her plot, spreading her rear so wide that her strained lips were pressing into the sides of her thighs. Meanwhile, deep inside her young body, Jet’s cockhead had just bumped against her cervix, hitting the final depth of her clenching vaginal tunnel.

Jet could feel that deep gate barring him, preventing him. But he still had four inches of fat, girthy cock out in the cold…

Well, maybe not so cold… it was currently being drenched by gushes of hot, spurting apo-nectar.

Still, if his heavy balls were telling his mind to do anything right now… it was to bury his bone. Bury it deep.

With another snort Jet lowered his head, bringing his face close to his daughter’s back, near to where the ribbon raced across her back, opening his teeth, he took a sizable nip of back fur and ribbon into his teeth, clamping down just hard enough to gain extra purchase for his thrusts… but not hard enough to hurt his precious little filly.

“Anhg! AnnnH!” Delighted squeals filled the air.

Jet continued his grinding thrusts, adding more power and tempo with each go, battering at her cervical entry, smashing his dome-tip into the tight aperture again and again and again.

Hre felt her body going limp underneath him… her rear legs getting wobbly and unsteady as she started to lose her footing, overwhelmed by the now steady power-fucking she was getting from her dad. But it didn’t matter - Jet’s hard cock was full enough and thick enough to support whatever strength the filly had lost in her legs… there was no way for her womb to avoid the insistent knocking of the alpha-stallion demanding entrance.

Slowly, methodically… the deep petals inside Apogee’s body began to unwind, untighten. Millimeter by Millimetre of her father’s thick, dome tip was slipping past that final gate. With the ending thrust of each buck, Jet’s pre-ejaculate burbling tip was poking into the very center of his daughter’s feminity, shooting out trickles of his stallion-laden lubricant, delivering potent injections of hormone-laden biochemicals into her sensitive, fertile garden.

And then, it happened.

Whether it was the puddle of her own slippery filly-honey, or the loss of muscle tone from the overwhelming pleasure shocks from her father’s steady, rhythmic powerfuck of her teenage plot… Apogee’s left hoof slipped.

All at once, she fell backward onto her father’s huge, invading pole… right as he completed the end of a particularly insistent thrust. The result was immediate.

All of Jet Stream’s considerable organ was rammed into his daughter. His huge, drooling cockhead stretched her cervical opening, pounding the final four inches of his cock into her womb, embedding itself into the far side of her deepest inner bit… poking a fat bulge from Jet’s angled, massive cock-end through her belly, a couple of inches above her belly button and just below her ribcage.

Her filly-lips somehow managed to part further, straining like a latex glove pulled over a basketball as the hoof-wide, girthy, trunk of Jet’s cock base squelched into her.

There was a moment of pure bliss as Jet savored the sensation of being completely wrapped by his cute daughter’s milking, cunt. Every vein, bump, and ridge surrounded by squeezing, gushing, silky fillyflesh… before his two heavy balls swung up and impacted against her teats with a wet *PLAP*.

He shivered with the odd sensation of total completion….

And then Apogee came. On his dick.

Hard.

Rhythmic waves of clenches surged through the filly’s exhausted, spasming body. Her whole clenching tunnel tightened like a vise around his cock, clenching down hard on his penis, milking and suckling up and down his length as her spine arched underneath him.

“MMMMMMNNN!!! MNNNN!!!” Her screams echoed out around the ballgag.

Wave after wave of contraction rocked his penis, each one culminating in a hot spray of filly cum that splashed out against his legs, as Apogee’s delicate clitoris writhed out and winked against the underside of his shaft.

Nature kicked in - his filly was creaming around him, desperately milking him. How could he be so cruel as to deny her?

With momentous speed, Jet began to piston his hips backward and forth, long arching thrusts that pulled half of his length out of the tornado-like coiling interior… before plunging back in with enough force to drive the tip of his cock in the diaphragm of the still-orgasming filly.

*SCHLORP* *PLAP*

The obscene squelch filled the room - first the wet splatter of his cock dredging out all sorts of sex-juice from her clenching flower… then the slamming wet plap of his heavy testicles swinging up to strike her in her lower abdomen.

*SCHLORP* *PLAP*

Again he drove into her, savoring the feel of all that twisting, orgasming filly flesh running over his rigid stallionhood, stretching and bulging out her stomach as he drove deep into her body again and again.

*SCHLORP* *PLAP* *SCHLORP* *PLAP* *SCHLORP* *PLAP*

He was picking up speed now, his body aching under the jackhammer like force that he was driving into Apogee’s smaller body. He was using all his weight to pound his fat cock down into her upright rear.

*SCHLORP* *PLAP* *SCHLORP* *PLAP* *SCHLORP* *PLAP*

“MMMM MMMM MMMM!” Her choking gasps were a backdrop to his grunt thrusts, he knew he must be driving her crazy - plunging his huge dick in and out of her as she continued to cream around his cock, a thick splatter of gooey juice now coating his shaft as it slammed in and out of her widening pussy.

*SCHLORP* *PLAP* *SCHLORP* *PLAP* *SCHLORP* *PLAP* *SCHLORP* *PLAP* *SCHLORP* *PLAP* *SCHLORP*

Harder! Faster! He could feel it now, rising in his lower belly… painful tension in his gut - his balls… a coiled spring getting ready to fire - a dam readying to burst.

*SCHLPLAP* *SCHLPLAP* *SCHLPLAP* *SCHLPLAP* *SCHLPLAP*

The sounds were combining now, his thrusts coming at a machine-gun pace, battering the far end of her little womb, pummeling her teats with his heavy balls. He was going to go harder, faster. Until his muscles broke… there was no regard for his well-being anymore, or even Apogee’s…. They just needed to empty this lust from their bodies, pound it out of themselves.

Apogee was still moaning like a whorse, still cumming on his pounding stallionhood… but now she was grinding back into him - using her hips to synch up with his punishing impacts - taking him even harder and more fiercely into her convulsing tunnel.

*SCHAP* *SCHAP* *SCHAP* *SCHAP* *SCHAP* *SCHAP* *SCHAP* *SCHAP*

*PLAP*

Then it clicked.

The perfect timing of a slamming thrust with Apogee’s needy grinding hips. With the swirling milking kisses of her cervix, the clenching twists of her fillyhood. The spattering winks of her clit.

It combined to push him over the edge.

To make him cum.

Buckets.

“AAAAAGggnnnH!” Jet let out a ferocious whinny, his chest shuddering. Before he tore back with his bite, pulling a small tuft of Apogee’s fur with him, along with ripping the ribbon off of her back.

He had truly opened his birthday present now.

His cock throbbed once, twice… his head flattening and pivoting even harder - growing to enormous size in her womb. A bulge of expanded cockflesh raced up his length...

And his cock erupted.

Heavy, filling blasts of virile seed… the same seed that had filled Delta Vee to make Apogee all those years ago… splattered into the filly’s womb. The firehose-like first shot blasted for over ten seconds - impacting the far side of her rapidly filling uterus with enough force to make a small bulge from the released pressure.

Jet groaned into the air, his eyes crossing over in sheer agonic pleasure. His balls were rapidly rising up to the base of his cock, clenching with powerful bursts of muscular ripples - squeezing himself dry of each pulse of thick foal batter, emptying his prostate and testicles of their potent fluid entirely.

Shot after shot creamed out of him in long, glue-thick ropes.

By the fourth release, his hips jerking and bucking involuntarily into Apogee as it flew deep inside her, the filly’s womb had been entirely filled. Cum sloshed in her belly like a hot, lake of goopy cream. But it had no way to escape the tight confines - the huge plug of Jet’s flare prevented that.

So her body did the only thing it could - expand.

Shot after shot poured into her… slowly expanding the teenager’s usually tight abdomen, inch by inch as she grew a small cum-belly.

“Unnnhhh….. Unhhh…..” Apogee’s gasps around the ball continued, groans of pure satisfaction as her beloved daddy crammed her full of his cum.

Finally, after the 12th rope trickled from his engorged cockslit, Jet felt his muscles relax - unwinding from their tonic clenching state and releasing him from the heavy tension that had held him in thrall for almost a minute as he pumped his daughter so full that she looked like she was two months with foal.

That’s when the endorphins hit him.

A wave of pure pleasure, crashing over him as the after-effects of a male orgasm blinded his neurons with searing delirium. He felt his legs wobble, then slip… and he fell onto his daughter, the two landing in a heap on the floor,

“F-f-fuck….” Jet groaned, his eyes getting heavy, and dipping shut. The last thing he saw as he fluttered into unconsciousness was the yellow wing of Apogee’s left side extending - now freed from the ribbon-binding that had restrained her.

…

Jet’s eyes groggily re-opened.

It hadn’t been long. His sense of time was enough to know that. He’d only been out for a few minutes, perhaps ten.

Slowly his body rebooted, sensation after sensation coming back online. His rational thoughts trying to compose himself as realized where and what he’d done.

“Jeez Dad, I can’t believe you knocked yourself out.” Apogee giggled from underneath him.

His eyes managed to focus, seeing now that the filly had removed the remainder of her restraints: the blindfold and the gag and the plugs. She looked up at him with her big ready eyes and a naught-filly grin.

“Mmmnghh…” Jet grumbled, his tongue heavy in his mouth.

“You’re kinda heavy daddy… can you roll over a bit?”

Jet slowly moved his legs, shifting his weight off of his daughter. IMmediately he realized the two were still connected.

His rapidly softening cock was still jammed in her, his flare still plugged inside her cervix, unable to withdraw… even as his shaft deflated, becoming more of a long, limp noodle than the terrifying thick log it had been moments before.

“A-apogee…” He worked his mouth open carefully, barely able to form words as the haze left him. “I thought… thought you were at your mom’s…”

“Aww, c’mon dad. I wouldn’t leave you all alone on your birthday.” She grinned up at him, looking over her shoulder.

He felt a strong clench around his cock, a deliberate squeeze.

“I am your big birthday present after all.”

Jet felt his cock suddenly pop free from his daughter.

*PLOP* *SQUELCH*i

The sound of a torrent of gushing cum, spurting out of his daughter’s cunny like a jetting waterfall filled his ears. He could feel the hot batter burbling out from behind her and over his soft penis, the lake of thick cream quickly filling both of them.

“Woah… you were… uh… really backed up huh, dad?”

“G-gee… I didn’t… use any protection! Are you…”

“Relax! Relax… you took some anti-fertility drink before, didn’t you? The flask?”

Jet blinked. “How did you kno-... but… even if you knew I got that, how would you know… what if I hadn’t taken a drink Apogee!?”

Apogee blanched a little bit, her eyes widening. “Uh, wow… I… oops?” She tried sticking her tongue out, folding her ears back.

“Holy Celestia, we dodged a bullet.” Jet groaned, resting his head lovingly on top of his daughter’s. “You should let me know about these crazy plans, honey. What if I’d come home with a colleague?”\

“Aww, but I wanted it to be a surprise!” Apogee harumphed, puffing her cheeks out. “Besides - you shouldn’t be coming home with any other ponies so late at night… right dad?:

Jet sighed, shaking his head softly. His little filly was a jealous mare. But now was not the time to argue about how he should still be able to see females his own age. Not when she was still leaking his fat cumload out of her snatch.

“Uh-huh… whatever you say, hun.” Jet grinned, extending his wing to cover the little filly in a hug.

Apogee mewled, wiggling underneath him and snuggling her sweaty body into his happily.

“Y...y’know dad… I am your birthday present.” Apogee shyly remarked, looking up into his eyes with those puppy-dog irises.

“Uh-huh?”

“And it is still your birthday - for another few hours.”

Jet blinked, looking down at his cum soaked daughter.

“And I’d hate for you to not get the full use of my gift…”

“A-apogee…” Jet stammered… as he felt his daughter’s hooves reach down to his soft cock, beginning to massage life back into it.

“Mmm… happy birthday, dad…”

Apogee grinned, as her father’s cock began to fill back up with blood, stiffening and extending with each beat of his heart… rapidly returning to its full size.

“Happy birthday indeed.”
