Shining's Mother's Day Gift

View Online

Cadance and Shining Armor pulled their bags out of the taxi as they arrived at the Sparkle family home. It was rare for the royal couple to get a day away from their duties of state up north. It was and rarer still to get a sitter for Flurry Heart; The little alicorn got up to so much trouble when they were away that nearly every babysitter in the Crystal Empire was scared to take the job, but they had managed to free themselves up for Mother's Day, same as they did every year.

The Sparkles' house was located up at the far end of a long driveway in one of the wealthy suburbs of Canterlot. A large yard coupled with tall trees gave the family its share of privacy, something that would have been harder to come by had the family lived in the city proper.

At the door, the couple could hear voices and movement inside. Cadance noted, "I guess your sister and Spike are already here, Shiny." Shining rang the doorbell, eager to give his mother her present and get started celebrating the special day.

After only a minute the pair heard footsteps come up to the other side of the door. Twilight Velvet swung it open, practically squealing with delight as she saw her son and daughter-in-law had arrived. "Oh, I'm so glad you two came!" she shouted as she ushered them both inside. The matriarch of the family was elated to have her family visit her for the holiday. Twilight Velvet was never good at hiding how proud she was of her son and daughter.

Once they had closed the door, Velvet teased her son, "Well, I hope you haven't gotten so big and important up there in the Crystal Empire that you can't give your old mom a hug!"

"Of course not!" Shining answered as he and his wife put their bags down by the door. He wrapped his arms around his mother, pulling her close to his body as she wrapped her own arms around him. It could have been a scene from any normal Mother's Day, just a mom getting a big hug from her visiting son.

That illusion of normalcy evaporated the moment Shining Armor loosened the hug just enough to bring his face up to his mother's and delivered a long, sensuous kiss. "Hmmm, someone sure has missed mommy," Velvet tittered before kissing back, bringing her hands to Shining Armor's shoulders.

Cadance watched the scene with a voyeuristic glee, biting her lower lip as mother and son kissed like lovers -- which, as Cadance knew, they were. Years ago when Shining Armor explained to his wife-to-be just how much his family was different from others, he had been terrified that Cadance would leave him in disgust, or worse, tell everypony. Instead, Cadance had been thrilled. She had not only accepted the arrangement but emphatically insisted that she become a part of it.

Twilight Velvet let go of her son, playfully biting at his lower lip as she turned towards her other guest. The two mares shared their own hug, enjoying the feeling of their matronly breasts pressing against each other's. Velvet felt like she was back in college, comparing busts with the other mares in front of all the hot studs at parties. Cadance had a wonderful way of making her feel like a young mare again, rather than making her focus on just how big the gap in their ages was.

Velvet guided them away from the foyer, acting as casually as if she had not just been making out with her own son. "Your sister and Spike got here a few minutes ago, dear." As they rounded into the grandiose sitting room, she called out, "Oh, Night Light, Twilight! Shining Armor and Cadance are here! Say hello!"

Night Light greeted them from where he was seated on the sofa, "Hi son! Glad you and the wife could make it down here."

"Nnnghh-Hff!"

Twilight's response was less verbal, occupied as her mouth was by her dear old dad's dick. Her eyes looked to her brother and sister-in-law, and she let out a muffled gurgle that might have been a greeting, but her father continued pulling her head down on his cock just as he had been doing before they arrived.

"GLUCKK!"

The other Sparkles looked at Twilight lovingly as her throat was filled with cock. Her sense of royal decorum was shattered. Her mane had been mussed from her father's grip, and her breasts were spilling out, braless, from her open blouse. The little makeup she wore was smeared around her face from the wear and tear of taking Night Light's oral assault. Night Light, in contrast, sat almost fully clothed in his seat. He looked as natural as if he were reading the Sunday paper.

Shining grinned at his sister, teasing, "What's the matter, Twiley? Too busy to say hello?" His sister responded by rolling her eyes at him, then closing them to focus on blowing her father.

Cadance asked, "Wait, Twilight's here, but where's Spi-HAAIIIEEEEEKKE!!!"

Her question turned into a shrill scream as Spike made his presence known. Sneaking up on her, he grasped Cadance's waist from behind and with a single motion drove the tapered shape of his draconic shaft deep into her ass. Her legs turned to jelly from the shock of the sudden anal invasion as Spike, fully unclothed, humped her like an animal in heat.

He spared only a brief look at Shining, merely saying, "Hey, bro, thanks for bringing Cadance," before grabbing Cadance's mane and tugging her head back.

Cadance half-stepped, half-fell forward and planted her hands on the coffee table, struggling to stay on her feet as Spike humped her. "Guh--Goddess, Spike," Cadance groaned, in a husky tone, "Give a girl some warning before you go balls deep in her ass!"

Spike might have believed Cadance was angry about the surprise butt-fucking if not for the fact she wasn't wearing any panties under her skirt. He revealed this to everypony else in the room as he ripped her skirt off of her waist with his powerful claws. He gave a hard smack on the princess's pretty derriere, clearly appreciating her choice of going commando.

Shining watched the dragon pump his thick, veiny rod in and out of his wife's tight backdoor. On one hand, he couldn't help but be proud of the dragon that had practically been raised as his brother as he smacked his dragon-balls against Cadance's pussy with every thrust. On the other hand, he was proud of his royal wife for taking such a hard, passionate fucking from the dragon.

Shining's own coal-grey cock was dropping from his sheath, starting to engorge into a monument to his mounting arousal. Velvet was clearly feeling the love too, stroking the mound of her pussy over the fabric of her black pinafore dress. Meeting her eyes, Shining grinned.

"Well, if everypony else is busy, I guess I could get started on giving you your Mother's Day present."

Velvet blushed but nevertheless sank to her knees, undoing her son's belt buckle with care. With motherly affection, the MILF undid his trousers, shimmying them down his thighs.

"Let me see just how much bigger my boy has gotten since last yea--Oof!" Velvet grunted as she pulled down her son's undies, only so get bopped firmly on the chin by his semi-erect shaft as it swung up out of its confines.

"Sorry, mom."

"No worries, baby." Velvet rubbed the spot on her chin that had been uppercut by the long, dark member. "I swear, you get bigger every time I see you."

Velvet cooed contentedly as she played with her son's flesh. She used both hands, cupping his balls with one hand as the other gently stroked his engorging member. As good as a stiff, hard cock felt in her pussy, she especially treasured the moment when one of her guys, whether it be Spike, Shining, or Night Light, was just at the edge of being fully erect. The way it felt like they were putty in her hands, the firmness, the way they got bigger and bigger before her very eyes.

Shining reached his hands down, meaning to grab Velvet's head and start using her in earnest, but his mother grabbed his wrists, giving him a stern look. "Tsk-tsk...Shiny, I know I taught you better than that. You should let a lady take her time with this sort of thing." She stared down the barrel of his cock. "After all, mother knows best."

After giving his cock a quick kiss, Velvet corrected herself. "Or, at least, mother blows best."


Shining's moans got everycreature else in the room to look at him, distracted from their own conquests, as Velvet enveloped his cock with her plump lips. Cadance's attention was brought back to the task at hand as Spike slipped a spit-soaked digit into her dripping cunny, probing around as his thumb stroked her love-button.

Meanwhile, Night light took advantage of the pause to pull his daughter off of his member. She let out a little gagging sound as the slobber-covered member pulled out of her throat, dripping spit and pre-cum onto the floor. Twilight's confusion at why anypony would stop fucking her face was cleared up right away, as her daddy pulled his trousers completely off. He undid his shirt and spread his legs apart in his seat to give his special girl a full view of his body.

Night Light had kept it in shape even into his fifties: Toned muscles, a chiseled chest, a strong, paternal jaw...and a long, hard, midnight blue stallionhood, just begging for a taste of her pussy.

"Well," he asked, "does my little princess want to take a seat on her throne?" Grabbing his shaft at the base, Night Light waved it side to side, beckoning his slutty daughter.

Twilight's answer was a girlish squeal of excitement as she jumped to her feet, turning around to give her dad a view of her butt. Too impatient to undress, she plunged a hand under her skirt and ripped her panties apart at the crotch, leaving just a useless ring of fabric around her waist. Her proud papa barely managed to guide his rod to her gash before she sank her hips down, melting into her new position on the throne of her father's lap.

"Mmm...Oh, fuck me, daddy!" Twilight groped and tugged at her own tits as her father entombed his stallionhood in her warm depths. His masculine musk was enough to drive her crazy, but he had been pumping those pheromones into her face at point-blank range for the last few minutes. Now, with the addition of his cock serving as a sexy seat for her princess plot, she was in heaven.


Shining watched his little sister as she bounced on Night Light's midnight blue cock. Every time her hips slammed down to meet her daddy's lap her skirt billowed out, letting Shining catch glimpses of the stallion's meat sliding into her. Part of him wanted to walk over and join them, giving Twilight an unexpected B.B.B.F.F.D.P., but he was otherwise occupied. The hottest mom in Equestria (Erm, other than his wife, of course...) was taking his cock down her throat all the way to the medial ring, and nopony in their right mind would walk away from that.

Velvet knew how to pamper her boys when she sucked their cocks. Everything from the way she hummed around his tip to the way she stroked his tummy with her hands made him feel like he was floating on a cloud. Of course, Velvet had years of practice on Night light before she had even started with Shining Armor or Spike. Anypony would have been an expert after so many hours of cock-sucking spread over their lifetime.

Velvet gripped her son's base with one hand, kicking her pace up from lazy, gentle bobs to eager slurps. Her tender tongue danced around inside her mouth, lathering every inch of his cock with a lubricating layer of spit. The wet sounds of her Mother's Day blowjob echoed around the room, harmonizing with the slaps of Twilight Sparkle's wet pussy on her daddy's lap and the smacking of Spike's hips against Cadance's ass cheeks.

Shining watched as his mom looked up at him, locking eyes as she blinked her long lashes at him. It was almost enough to push Shining over the edge right there, staring into those two blue pools of motherly love. But as he started to flare Velvet did the unthinkable and pulled him out of her mouth.

Shining panicked; Was Twilight Velvet actually going to blue-ball him? Had he done something wrong? He stammered, "Muh--Mom!?"

Blessedly, Twilight Velvet was not finished yet. "Shhh...Shhh...It's okay, baby," she cooed as she stroked his dick, so close to bursting he could see the veins on his cock throbbing.

She planted a long, dramatic kiss on the flat head of Shining's throbbing shaft. "Mmm...My big strong boy..." Shining grabbed his mom's shoulders to steady himself as she brought her other hand to his medial ring. Her thumbs worked in concert massaging it as she planted loud kisses all over his flare, puckering her lips around the bumps around the edges and his quivering cum-slit. "That's my boy...Good boy..."

Shining roared as cum spurted from his flare, launching two thick, hot ropes of creamy goodness over the sweater his mom wore under her pinafore. Velvet directed his spasming shaft to her mouth where a third burst of jizz bubbled up against her parted lips.

*Slurrp!*

"You came so much, baby," Velvet cooed, her mouth sticky with cum. Her delicate hands toyed with Shining's cock. "You always give me the best -- Oh my!"

Shining grabbed the shoulder straps of his mother's dress and yanked them down, letting her now cum-stained dress crumple around her waist. Shining bent over. "Ready for part two of your present?"

Velvet blushed. "Mmm...yes please." Not missing a second, Shining reached down to gently push the mature MILF onto her back and tear off her remaining clothes. Kneeling down between her legs, he lined his slick, still-hard shaft up with her marehood like a hunter lining up his arrow to shoot at his prey.

Shining's stallionhood was still flared as he touched it to Velvet's entrance. A few experimental prods and pokes yielded nothing; Velvet's honeypot resisted Shining's flare's saucer-plate-sized flare too much for him to gain an inch. Shining gritted his teeth. "Mom, I can't --"

"Don't you give up on me, mister!" Velvet interrupted, winking at her boy. "Your mommy didn't raise any quitters." Her horn shone with a cerise glow as a magical force gripped her hips and her son's.

She grinned. "I'm going to get my Mother's Day gift from you one way or another." Then the magical force pushed their hips together.

*SCHLOPP*!

The wet sound echoed in the sex-filled room as Shining's girth broke the seal, driving into his mother's warm love-tunnel. He was well and truly inside of her, the knobs of his flare digging into her juicy walls, smearing his rod with her sticky juices.

As he slammed forward, Shining nearly doubled over in pleasure, bringing his face close to Velvet's as her mouth opened in a silent scream of ecstasy. Those kissable lips, that talented tongue, the smell of his cock still on her breath...I really do have the world's best mom, Shining thought. Then he dragged his shaft back a few inches before thrusting forward, pushing his girth into the tight tunnel, grunting with effort like he was pushing a fully loaded sled.


Twilight watched her big brother fuck their mom. She had a wonderful view of the pair of unicorns from her seat atop her father's cock. Even now the length of daddy-dick slid in and out of her, shooting out a little splash of marecum every time the medial ring squeezed through her entrance.

Buck me...Shiny's so hot. The princess licked her lips as thrust after thrust rocked their mom's luscious body, sending her big, milky tits rocking back and forth.

Night Light watched with a sense of paternal pride. He loved seeing his family getting along so well. He kissed his daughter on the nape of her neck before whispering in her ear, bouncing her on his cock all the while, "Is my little princess thinking of her B.B.B.F.F.'s cock?"

"Hmm...Yes, daddy..." Twilight nodded as her DILF drove his cock into her wet pussy again.

*PLAP*

"Aw, if you're not careful you'll make your old man jealous."

*PLAP*

"Not that I blame you. It's such a thick cock, I bet your mom's having the ride of her life right now."

*PLAP*

Twilight agreed. Her mom's hips were practically bulging as Shiny's massive dong pushed into it. Still, she reached behind her, stroking a hand along her daddy's masculine jaw. He was doing such a good job of stuffing his daughter full of cock. He deserved her undivided attention.

"I'm sorry, daddy! Sweet Celestia, you're so bucking big." She could feel his shaft getting bigger, twitching, ready. He would finish inside her soon. She was so eager for his load she sweated with anticipation. Here was the undisputed alpha-male of the Sparkle family, ready to fill her up with the same virile cum that had sired her. It was an honor to be creampied by such a stud. Night Light didn't just cum in the mares he bred; He anointed them.

Night light grinned. "Well, Twi..."

*PLAP*

"If you promise to be a good girl..."

*PLAP*

Night Light grabbed Twilight's hips, ripping off her skirt, his cock so close to cumming it was throbbing...

Pulled her off of his lap and set her on her feet.

"Go over there and give your mother her Mother's Day present."

Twilight was flabbergasted. Her dad had blue-balled not only her by denying her a warm filling of daddy-batter, but had blue-balled himself as well! "But daddy, I--"

Twilight's expression soured as he put two and two together. "You just want to finish inside of Cadance, don't you?" She leered over at Cadance, whose butt was getting red from Spike slamming into it so much. Spike breathed sharply as his balls tightened up in their scaly pouch, pumping another hot load of dragon-cum up the young mother's asshole. Cadance let out a pathetic groan as the dragon's cock stretched her hole, widening as the rush of virile fluid painted her guts white.

With the stamina of a dragon, however, Spike immediately resumed the anal assault on the princess. Twilight knew from first-hand experience that Spike would have more in the tank, so to speak.

Night Light shrugged as he pushed his bottomless daughter off towards his own wife. He had been found out, but he wasn't going to let that stop him from double-dipping in princess pussy today.


Shining sweated with effort as he pushed into his mother, his fat medial ring smooshing against her clit as they met. His tip's flare had settled back down, but his medial ring was posing a new challenge. He'd gotten this far, however, and he didn't plan on stopping now. Staring into Velvet's eyes, he asked, "Ready, mom?"

She nodded. "I'm ready, babe."

Shining gripped her shoulders as he readied his hips. "Okay...One..."

Shining waggled his hips, loosening up his mother's honeypot. The veins along his coal-grey length rubbed against her walls, making way for the impending arrival of the last few inches of stallion meat.

"Two..."

Velvet grabbed the carpet, bracing herself for the bulldozing force of her son's cock.

"THREE!"

Shining bucked his hips forward, pushing his mom back a few inches before her hole gave way. His ring, and the inches of cock behind it, entered her pussy, pushing through a vise-like squeeze. Velvet's eyes lost focus as she came, gushing marecum all over Shining's groin as the much thicker base of his cock hilted into her. Dazed beyond reason, she gave a warm smile as her son's cock was buried completely within her depths, the tip poking in past her cervix.

"W-welcome home, son."

Velvet wrapped her smooth, pale legs around her son's waist, holding him in as her vaginal muscles milked his dick, begging him to cum in her. It felt like her pussy was sucking his cock even deeper in. Feverish with pleasure, Shining slid his hands from the MILF's shoulders to her breasts, groping them and squeezing them as if his life depended on it.

While Shining focused on his mom's milk jugs, Twilight walked over, sliding out of her already undone blouse and torn panties, her last remaining scraps of clothing. She came to a stop standing right behind Velvet's head, looking down as Shining gave their mom the dicking of a lifetime. Her voice coming out shakily, Twilight said, "H-Hey, mom...um...wow." She couldn't stop staring at where Velvet's child-bearing hips met Shining, where a long, tubular bulge trailed up towards her belly button, marking the depth of her son's carnal conquest.

Velvet reached up and caressed one of Twilight's legs. "Oh, I'm sorry mommy hasn't been paying attention to you today, sweetie." Pulling her daughter forward a step so that she was straddling her face, Velvet looked up at her daughter's marehood, so recently stuffed with Night Light's hot cock. A few drops of pussy-juice rained down onto Velvet's face as Twilight stepped forward, and the MILF couldn't help but lick it up with her tongue.

"It's a little late in the day for me to be asking my kids for breakfast in bed, but I can't help myself when you taste this good..."

Twilight obeyed the older mare's Mother's Day request, kneeling down low enough for her mother to open her mouth and devour her cunt. Shining had been so focused on his mom's tits that he had barely noticed Twilight enter the fray, but now he paid attention as his mom lapped at Twiley's dripping pussy, juices soaking her chin. "Buck me, Twiley, you're really giving her a mouthful," Shining observed as their mom messily ate her daughter's twat.

The Sparkle siblings turned their heads to look at the source of a loud, deep groan. They saw that while Spike's battering of Cadance's asshole continued on, Night Light had taken her from the front, lifting one of her legs up to his waist as he plowed her pussy. The pose gave Twilight and Shining an excellent view of both of the pink princess's holes getting stuffed.

It was a perfect match. Night Light was the kind of stud that loved to pound a mare to the point where they were absolutely devoted to his cock, and Cadance loved to get fucked like a ragdoll, getting her holes pounded as hard as a stallion could manage.

Shining gave a mischievous grin. "Hey dad, if you really want to have some fun you should try kissing her horn. She goes crazy whenever anypony does that."

Cadance looked surprised as if the mention of her kink had snapped her out of her lusty trance. Night Light just grinned back. "Oh, really? Well, I guess it would be rude not to indulge our guest." With a firm hand, he grabbed Cadance by her hair and pulled her head down, putting her horn right in front of his lips. She seemed to freeze as Night Light placed a single, delicate, loving kiss on her horn.

Then Cadance went, as Shining had promised, crazy.

"OH FUUU-HHHHAAAACKKKHH!!!" Cadance screamed as her other leg flew up, wrapping around the DILF in front of her. Every muscle in her body seemed to shudder in a wave that, when it reached her pussy, erupted in a magnificent, messy squirt.

Night light had to break the kiss to shout, "Oh, sweet bucking Celestia!" as his balls raced up, pouring cum into the Princess of Love as his shaft flared inside of her. Her tummy rippled as her muscles contracted, practically sucking the cum up out of Night Light's cock and into her fertile womb.

At her age, Velvet wasn't popping out any more foals, and Night Light tried not to knock up Twilight during their daddy-daughter time, but Cadance was, in his opinion, fair game. He might very well end up with a second alicorn daughter nine months from now. He smiled. Now wouldn't that be something?

Shining continued his own task of stuffing his mom's muff, humping in little thrusts to avoid popping his medial ring out after all the trouble he had gone to just to get it inside. Every time he bottomed out she gave an approving moan that was muffled by Twilight's dripping pussy. Despite the messy-looking technique, Velvet was taking pains to keep her daughter just on the edge of orgasm. His usually fastidious sister was being reduced to a babbling pile of purple mush.

He couldn't help but eye her horn. It works for Cadance. Maybe it's a princess thing? Without warning, Shining grabbed his sister's head with both hands, turning it to face her.

"Big...Big bro?"

Twi gasped as he pulled her head down and put her horn in his mouth. He didn't just kiss it -- He sucked, using everything he knew from his experiences with his mom doing down on his own much thicker pole.

Oh! H-Huuhh..." For a second, it looked like his theory was wrong. There was nothing more magical going on than one unicorn sucking on his sister's horn. Maybe Cadance was the only alicorn who --

A purple spark crackled around Twilight. She tensed up as a glow built up around her until she seemed like a blinding supernova in the middle of the sitting room.

"Oh, Sh-SHINEEEEEEY!!!" Then it pulsed out; A wave of purple lightning that arced from Sparkle to Sparkle, reacting in a shower of technicolor sparks when it hit their horns (or, in Spike's case, the scales cresting his head).

The magic penetrated every inch of Shining's body, from his horn, to his spine, to his manly, swinging balls. Evidently, everycreature was affected similarly, as Cadance got a serving of the spell's effects from both the front and the back,

Spike gritted his teeth as the muscles in his neck tensed up. He was used to cumming many times in a row, but Twilight's spell was going to make him cum so hard all at once it would exhaust even his massive stores of seed.

Rope after rope of virile dragon-cum shot out from Spike's dragon-dick, filling Cadance's ass up to the brim. Spike moaned, "Ghh...Gaah!" as all the cum started to ooze out around his cock, lubing him up with his own juices. His shaft slid out as he slumped down onto his back, exhausted. He was powerless to stop his shaft as it flailed around, still going strong as it sprayed cum onto his own chest, showing no signs of stopping.

Meanwhile, Night Light's magically reinvigorated stallionhood punched forward into Cadance's womb, blasting seed into the fertile mare. He panted and gasped as he saw his daughter-in-law's normally lean tummy bulge out with the fullness of his orgasm. Her gravid gut was like a testament to Night Light's virility. Well, she's definitely knocked up now, he mused.

Shining was too busy to watch his dad impregnate his wife. He was occupied by his own pair of mares, getting blasted by Twiley's wave of sexual magic at point-blank range. His saucer-sized flare plugged his member tight in Velvet, sealing in the tidal wave of jizz that hosed out through his urethra. His gushing seed sought out every nook and cranny of his mother's depths. The very womb he had come from was flooded with his semen, expanding to fit the massive volume of cum.

"Muh...Momma..." Shining poured all his energy into creaming his mother, unable to stay upright. He slumped forward, his head landing in his little sister's bosom as she twitched and shuddered, electrified with the feedback from her spell. Her mind was blank except for thoughts of lust, held by her B.B.B.F.F. as he pumped their mom full of cum.

Velvet's belly felt so warm, filled as it was with the hot, sloshing load of her son's jizz. Her special little guy was such a good, strong stallion, giving his mommy such a wonderful Mother's Day gift in front of the whole family. Everypony could see how much Shiny was giving his mom as her belly filled out, magically stretching to accommodate Shining's prodigious load of stallion-batter, courtesy of Twilight's spell. By the time his orgasm died out her belly looked positively pregnant.

Velvet's son and daughter fell back, completely spent. While Twilight simply tumbled over unobstructed, Shining's member schlorped out from his mom's hole as he pulled away, making a sound like pulling the plug on a bath drain. Cum spilled out of her gaping hole like milk from an overturned carton, staining the floor in a big, sticky puddle.

*Glugg, glugg, glugg...*

All around the room the members of the sparkle family lied down, completely exhausted from the Mother's Day bacchanal. Velvet smirked. I bet I'm still going to be the one that has to clean this up. She knew that in an hour or two, everycreature would be up again and raring to go. Before the day was done, she'd have a taste of her little Spikey, and her precious daughter-in-law, and even her own husband (how scandalous!).

Velvet's smile widened as Shining roused just enough to say one thing:

"Happy Mother's Day, momma."

She really was the luckiest mother in Equestria.
