Time for round two.

“Mmmf! Yeah!” Apogee squeaked, wings again stretching outward as she felt her mother’s girth begin to press into her once again.

‘Fuck yes! Rut her! Do it!’ Delta sighed with contentment, the feeling of those tight young cuntlips straining, stretching… just barely parting for her insistent press… until all at once sliding over her fat knob like a deliciously warm and soaked velvet glove.

With her newfound leverage fucking in the pony-style position, Delta was able to drive herself in all the way to her medial ring with the first stroke… there was so much power in her hips, so much fierce, burning need… only the fat ring of the half-way point of her cock prevented her from ramming home her whole shaft.

“Ahn! M-Mom!” Apogee squeaked, trembling and wincing with the sudden sharpness of the penetration - her wings shooting out wider in surprise. A squelching, obscene sound escaped from their union as Delta’s aggressive plunge drove into the depths of her daughter’s body.

She hadn’t meant to be rough - but it was just… so easy… so right!

‘Harder! Harder! Deeper! She wants it! Come on!’ Her mind, her body wanted more… and she hoped… needed kid to want it harder as well.

Delta started to pull her hips back, preparing to ram herself home with even more ferocity. As her cockhead retracted it plunged out Apogee’s tight teenage snatch, stretching and straining it, causing the filly to let loose a squelching squirt of juice that spattered over her mother’s thighs.

The filly was winking. On her stallionhood.

‘Now!’ Delta thrust forward, sliding six inches of throbbing pink meat back into Apogee, right back up to her medial ring… which stubbornly caught in the vise-like grip of the filly’s labia. For a moment, her cock strained and bulged, almost bending under the resisted force of her hips and the blocking grip of vaginal obstruction.

“Mmmf! Y-yeah!” Apogee wiggled her hips backward into her mother’s pressure, shifting with clenching butt-waggles to try to wedge more cock into her small body.

Her lips parted, ever so slightly, peeling around the fat ring of cockflesh…

...and Delta felt the incredible grasp of fillycunt around her cock’s base, as inch after inch sank into Apogee’s twisting depths.

‘Fuck yes! Yes… yes! So tight!’

Even though Delta had been on the receiving end of much more prodigiously-endowed stallionhoods which dwarfed her own well-sized organ in length and girth… or in the case of Apogee’s father both… there was something marvelous about watching such a small, tight plot take in something so large. It had always felt good when a big stallion like Jet hilted her… but being on the other side of that, seeing her most sensitive body part being almost completely engulfed by somepony who seemed to improbably small to do so…

It was intoxicating.

‘Fuck her! Move, move, move!’ Delta bit her lip, the burning stimulation of the engorged male part of her body pumping her full of hormones, of desire… wanting more than just the stimulation of being gripped by those filly-walls… it needed to rub itself into them, to grind along those slick, swirling fleshy coils of teenage snatch.

And Delta wanted it too... because she knew Apogee wanted it. Wanted to be rutted hard. Delta might be a novice at bucking as a stallion, but she could at least recognize those wiggles, those shudders… the breathy moans… the way her filly’s primary feathers were pulsing wider with each of her heartbeats… she did the same thing when she wanted her latest barfly conquest to pound her into happy oblivion.

So… why shouldn’t she give the kid what she desired?

Delta slid her hips back, drawing her nearly-hilted cock out of Apogee’s straining and stretched pussy. The tight, pink, velvet-glove lips slickly drew back over her shaft’s every vein and bump, over her ring and all the way out to her cockhead… before she slammed herself back in… a wet squelch accompanied the thrust as she drove ten inches of raw mottled blue and pink cock into her filly’s cunt.

“AH! Yes! Mom!”

‘Faster! More!’

Delta quickly repeated the process, drawing and slamming her hips with more confidence and speed now. The filly’s wings were flaring out completely now, straining and flexing in time with her thrusts.

Quickly Delta found her rhythm, steadily slipping in and out of that incredible cavern, rutting her daughter’s plot. Her confidence growing, Delta glanced up from fixating on the filly’s ass - she wasn’t worried she was going to slip out like on the couch. Her eyes traced up the sweaty, shaking tail, over the cat-like bend in Apogee’s lower back, past the disheveled hoodie and over the dripping blue-green mane… looking instead into the mirror across the room.

Apogee’s red eyes were fixed on her face, sparkling with a new intensity. That contentedness was still there - the joy in being with her mother… but a new fire smoldered now. The way her eyes seemed to be unfocused, the way one eyelid drooped below the other... the way her tongue hung out the side of her panting mouth…

Apogee was losing herself to the pleasure.

Delta managed to grin in between her panting breaths. Pumping like this was taking more out of her than she thought, vigorous pumping of the hips required quite a bit of exertion. But it was worth it to see, to feel the lustful joy that she was giving to Apogee.

Delta knew that look, that drooling tongue. She’d worn it herself many times after a successful night of trolling at the bar. And Delta knew what she would have liked when she was in such a situation.

*Slap!*

With a hearty swing, Delta brought her left hoof down with a cracking impact on her daughter’s flank, leaving the echoing smack of flesh and a red mark in its wake. The impact sent a ripple of force through the muscular glute, jiggling Apogee’s already pounded plot.

“Ahn!” The mix of pain and pleasure made Apogee yelp a groaning squeak.

“You like that, kid?” Delta growled sultrily, her hips starting to move faster, automatically… instinctively.

“Uhn… uhn… uhn… y-yes!” Apogee yelped, in between gasps.

“You sure run hot, honey…” Delta teased, bringing down her hoof once again with another slap...

*Slap!*

“...just like your mom.” This time Delta kept her hoof against the spot she’d slapped, digging in the edge of her hoof and taking hold of Apogee’s hipbone. She quickly found the new grip letting her pull with her hooves, gaining more traction to slam her hips with more ferocity and speed.

‘Fuck her. Harder! Harder! Make her squeal!’ Delta quickly gripped the other hipbone, flexing her arm muscles to pull herself with powerful force into Apogee’s teenage plot. Her legs, her hips, her lungs and heart… everything was burning and strained. But it was like her body had a mind of its own… like she was running on the instinct of her stallionhood. Her mind was just along for the ride, millennia of instinctive biological conditioning were now firmly in the driver’s seat.

And she didn’t mind one bit.

Delta felt her nostrils flare, drawing deep breaths of the musky, sex-fogged air. That tart-sweet smell of squirting fillypuss stoked the raging inferno of her lust into a firestorm. She leaned in to her thrusts, bending over Apogee’s back, letting her sweat drip from her soaked tanktop onto the filly’s arched back.

“F-fuck!” Delta groaned as her cock hilted for the first time in her daughter’s fillyhood. The stallion-stud instinct inside her clicked up another notch at the feel of that winking pussy take in the last, girthy base of her cock. She felt the wet embrace of her daughter’s clitoris against the top of her scrotum and felt it draw back in a bumping, strand-trail-leaving path over her shaft’s uneven surface. The pink lovebud bounced over her medial ring in a burning line of kisses right up to the underside of her glans... before she plunged all the way back in, stretching the filly’s cunt back to its widest as she hilted again and again.

“Unf! Unnf! Unf! M-Mom… I’m… unf! I’m g-gonna… UnNf! M-om… MOm… MOM!”

The deep, power strokes were having an effect - Delta could feel her daughter’s gyrating motions becoming more erratic under her, the humps back against her getting mistimed, sloppy, wild. The swirling clenches of the filly’s pussy no longer coordinated, but spasmodic, as if the nerves of the filly’s body were malfunctioning, blasting at random times in reaction to the waves of pleasure Delta was giving her.

*PLAP!*

The sound of wet flesh slapping against wet flesh filled Delta’s ears. Not just the impact of hip against flank, of sopping fillyhood against pubic bone… but of Delta’s heavy balls swinging up to strike against Apogee’s lower belly, just under her teats. The two dark-blue orbs were dripping with Apogee’s filly-nectar, which spilled out of her wet gash to coat the pair of erotic weights. Swinging like a sock filled with two cannonballs, they thudded against her daughter’s body in time with Delta’s animal thrusts.

*PLAP!* *PLAP!* *PLAP!*

Apogee’s head rolled up, craning her neck back as she took in a deep lungful of air. Delta could see the filly’s crimson irises shifting, molding, changing into heart-shapes and start to roll up into her head. Her body was wracked by a spasm, shooting the filly’s wings so wide that wide gaps had appeared between each of her long primary feathers, her spine arched precariously, like a cat stretching after a nap… Delta knew those signs.

She was going to cum.

*PLAP!* *PLAP!* *PLAP!*

But Delta’s studly instincts didn’t care. The instructions from the feral, testosterone-fueled recesses of her brain didn’t care about how the filly felt. They didn’t care about making her feel loved, or pleasured. They didn’t even care about getting more sensation for Delta’s cock. They didn’t care about maximizing the already overwhelming sensation of pussy-flesh on her cockhead. There was only one word ricocheting around her consciousness now.

Breed.

*PLAP!* *PLAP!* *PLAP!*

‘Rut her! Rut her! Buck her! Fill her up with your cum. Drown her womb in stud-batter! Fill her with your foal!’ Her cock screamed in her psyche, too loud and furiously for Delta’s addled consciousness to resist, to consider just what she was doing… this wasn’t her daughter now. She was on the ancient open plains of Equus, an alpha stallion in rut… and this was her mate… her brood-mare… her filly.

*PLAP!* *PLAP!* *PLAP!*

“Gah… gah… gah…!” Apogee was gasping with chokes now, trying and failing to draw enough breath to sustain herself as she endured Delta’s onslaught.

It wasn’t easy for Delta either. Her heart was pounding far too hard for an alcoholic smoker, her muscles burnt worse than a champion sprinter after a race. There was no way for her to sustain this… and yet no way she could stop now, she would die first.

Delta fell forward, her forehooves landing on the outside of her daughter’s as she completely covered her. The new weight on Apogee’s back made the filly lose her grip, falling onto her elbows and slamming her face into the sheets of the messy bedspread.

This only served to further stick Apogee’s quivering bottom up into the air, as her mother’s new position served to allow even more powerful, continued, jackhammer-like strokes into her pre-orgasmic pussy.

*PLAP!* *PLAP!* *PLAP!*

Delta’s head was resting right on top of Apogee’s now, the sweat-drenched blue mane tickling her nostrils and getting into her open, gasping mouth as she pounded, harder and harder. Her muzzle was only inches from the filly’s face now, so every gasping, breathy squeak reached her ears, dimly registered and thrown onto the fuel of the now unstoppable blaze of feral rut.

*PLAP!* *PLAP!* *PLAP!*

The aching squeeze in Delta’s gut was concentrating into a central point, deep in her gut, the need and instinct boiling into a physical manifestation… sliding into her groin… into her balls… like a coiled spring winding too tightly, metal under tension… a cannon primed with too much powder.

‘Cum! Cum! Cum! Release! Fill her!’

*PLAP!* *PLAP!* *PLAP!*

She felt her balls shoot up… and slammed herself one final time, as deep as possible, hilting with a finality that natural instinct demanded.

By pure instinct she twisted her head and opened her mouth, taking a solid hold of her brood-filly’s neck with her teeth, steadying her to hold her in place as the inevitable sequence raced to a conclusion.

As soon as the teeth grazed that slender, yellow neck, Apogee screamed.

“M-! M-Mom! MoMma! Mommy! MomnmmMmmMAAaaaaaaannnnnnnngh!!!’

The tight, convulsing filly-cunt began to spasm... milking with powerful, needy, demanding clenches. Huge splatters of hot, gushing nectar sprayed from Apogee’s plot against the soaked pubic fur of Delta’s body, sputtering in wet waterfalls to the floor.

Apogee was cumming.

Hard.

The filly’s orgasmic contractions raced up and down Delta’s hilted cock, pulling inwards and upwards. Delta could feel the filly’s cervix pressing down against her flaring stallionhead, the tight opening kissing up against her cockslit and forming a perfect seal.

‘Now! NoW! NOW! NOAOAWUAHhhh….’ Delta felt her mind flaring out, replaced with a surge of white-hot pleasure as potent aphrodisiac-laden neurochemicals flooded her mind.

Her cock, impossibly stretched and thickened, extending by an inch with rigid, throbbing pulses. Tilting upwards, the pink end of her penis blossomed like a flower, flaring out to the size of a saucer plate and lodging itself firmly in the depths of Apogee’s vaginal snugness.

She felt huge… bursting… Like half her blood was in her stallionhood. Aching to explode.

Then it happened.

There was no force in all of Equestria that could prevent the huge rush of release that exploded out of Delta’s body... Not even if all the princesses could have slowed the searing rush of hot stallion-batter as it bulged out of her churning balls and down her shaft, straining the filly’s body as the massive load surged in a wave down her fat pipe to erupt out of her

A jet of heavy, white-hot stud-batter shot into Apogee’s pussy. The thick explosion fired right through the filly’s suckling cervical opening, impacting against her back uterine wall with enough velocity to deform the tender, hidden refuge. The blast seemed to last for seconds, quickly filling up the diminutive teenage womb with a creamy genetic payload.

Delta chewed down harder with her teeth, cinching her hips in with grinding hip thrusts, imparting just that little bit of additional momentum to each spraying cumshot. Those grinds were met by Apogee’s instinctive backwards pushes, feral thrusts that sought to collect every last drop of her stud’s sizable donation.

Blast after blast ripped out of Delta’s cock, each one accompanied by indescribable physical and emotional sensations, everything just felt right, natural, complete. Her brood-filly underneath her getting pumped full of her foals.

Each aching shot drained the burning need from her gut, her balls, her cock, her mind. In its wake was left only a perfect serenity of mind-melting dopamine and oxytocin.

She could feel the same consciousness-frying chemicals affect her filly underneath her. The tensed, straining, sweaty teenage muscles unlocking and unwinding as the filly’s belly began to bulge and expand, each ejaculation cramming her womb with glue-thick filling.

She lost count of her cumshots after her seventh blast, which somehow seemed to be just as ferociously powerful as the first, not tapering one iota… her over-productive stallionbits more than keeping up with the demands of her huge orgasm.

Apogee’s belly grew and fattened, her womb stretching to the size of a mare with foal… at first a small bump, then a bulge, then expanding out as if she were halfway through a pregnancy… her belly-button popping cutely out of her yellow tummy-fur as she was stuffed with her mother’s cum.

Only then, completely filled to the brim, did Delta’s batter start to overflow from their tight union, spilling out from the seal of lips to cock-base with squirting intensity, splattering in splotchy steaming sputters onto the floor and forming a lake of sexual juice beneath their hooves.

Feeling her orgasm finally weakening, the clenching spasms that drove cum out of her balls relaxing as it wrung out its last, thin squirts… Delta released her love bite.

Her eyes were rolling in her head, eyelids drooping and weakening, she could feel parts of her mind shutting down, weakening and winking out with exhaustion.

But she could sense Apogee nearby, still connected with her. A panting yellow form, dimly visible through the haze of post-orgasmic bliss. The filly slowly turned her head from where it had been buried in the sheets, craning her neck to try to look directly at her mother with her heart-shaped irises.

Delta could feel her daughter’s heartbeat through her body, through her still-stiff cock. Like they were one pony now, no longer set apart by the pains of time and the cruelty of circumstance, just one in union and love. She could feel that adoration from the kid… and could feel herself returning it in turn… her cynicism and pain out of the way for just long enough for her to love her daughter with pure intent.

It was perfect.

Delta leaned forward, taking her daughter’s muzzle in a deep kiss. Her experienced tongue made its way into the shaking filly’s muzzle, tongues interlacing and grinding without purpose, just in raw expression of love.

‘I love you, kid.’

Delta felt her eyes going dark, black, like a tunnel sliding up from the outreaches of her vision… a curtain being drawn over this exquisite play.

‘No! I don’t… I don’t want it to end… I don’t want to stop… loving... ‘

But it was too late… Delta felt the sleep overtake her, the last things she felt being her daughter’s tongue, her heartbeat, her fillyhood around her cock… and her love.

Then nothing.

PLEASE LIKE AND COMMENT!

I write for your feedback! I would love to hear more about whether you like Delta and Apogee and what you think of them - please share and keep my motivations fueled!

Oh boy!

I sure hope that Apogee was on her foal-control! She probably was if she was planning to have a 'special night' with Jet.

Can you imagine how much of a shit-storm that would be if she wasn't? Imagine how much of a hypocrite Delta would be, and the rage that Jet would feel if she of all ponies knocked up their teenage daughter!?

Definitely a funny possibility to think about.
