Double the MILFs, Double the Fun
Spike,
We know this may seem sudden, and very awkward, an awful lot to ask of you, but both Night Light and I find ourselves...incapable of keeping up with our wives' extensive libidos any longer. Our wives will be coming to Ponyville to meet with you tomorrow afternoon.
Best of luck with them, and we trust you will give them a wonderful Mother's Day.
- Shining Armor & Night Light
Spike stood resolutely in front of the door to Aloe and Lotus's spa, still re-reading the letter in his claw which he still scarcely believed was real. Tucking it securely into his messenger bag, he walked through the glass double-doors and greeted the two mares at the front counter with a toothy grin. "Hello there, ladies!"
The oppositely-colored twins smiled back at him and inclined their heads in greeting.
"Hello, mister Spike! It is good to see you on this fine day!" Aloe replied cheerily, her Stalliongrad accent giving an exotic lilt to her somewhat stilted Equish. "What can we do for you today? A back massage? A scale polishing, perhaps?"
Lotus's face fell as she noticed the conflicted expression on Spike's face. "Oh, my. It seems you have more serious troubles than a spa treatment. What troubles you, my dear Spike?" She asked, eyebrows knitting in concern.
"There's going to be two women coming in tomorrow, probably early afternoon. They...just lead them to the private room in the back and don't disturb us, okay?" Spike asked, glancing away from the mares' faces in embarrassment.
The sisters shared a surprised glance before blushing and giggling fitfully. "Oh, my! Two women at once, and on Mother's Day, no less? Go get them, tiger~!" Lotus exclaimed, giving Spike a playful jab on his muscled, scaly shoulder.
"May we be so bold as to ask who will be coming? We do have a right to know who is...enjoying our more exotic services, after all!" Aloe inquired.
"Uhh...you both have to promise not to tell anyone about this. Not even Rarity!" Spike replied nervously. "Seriously, if anyone hears about this, it's gonna cause a lot of awkward questions and really awful gossip."
"You have our word as masseurs, Spike! We hold the secrets of our clientele in the highest confidence!" Lotus responded, looking insulted at the implication of them gossiping their clients' private affairs away.
"Okay...well, uh...it's Twilight Velvet and Princess Cadance." Spike admitted.
The two mares gasped in surprise and astonishment. "Truly? The Crystal Princess and the mother of the Element of Harmony who raised you?" Lotus asked in disbelief. "I would think both of their marriages to be rock-solid!"
"Heheh, yeah, here's where the really awkward part comes in...both of their husbands actually approached me to set this whole idea up. Evidently, Velvet is...too promiscuous for Night Light to handle anymore, and Cadance is, well, the Princess of Love. Her "heart" is too big for just one being, or so Shining tells me."
"My, my! Well, we shall treat this as a private booking, shall we?" Lotus responded, winking at her sister. "I'll open up the spa for you tomorrow morning, dear, and leave these lovely ladies to your highly experienced claws~!" She teased, grinning at Spike's embarrassed, hesitant smile.
Spike fidgeted nervously as he twiddled a pen at the spa's reception desk. "Man, I really don't know if I'm ready for this..." The young drake said to himself, staring at a spot on the wall in contemplation. He was so lost that he didn't even hear the chime rattle on the spa's front door.
"We'll try not to leave too many bruises, then, oh "Brave and Glorious" Spike!" Cadance commented wryly as she entered.
Velvet and Cadance shared a motherly chuckle as he fumbled the pen he was twiddling and awkwardly tried to act like he hadn't just had his draconic wits scared out of him by a pink pony princess. Rubbing a claw through his head fringe, he addressed the two mares. "H-heheh. If you'll follow me, ladies, we can go somewhere more comfortable and, uh, get down to things."
"My my, it seems Spike wants to get right to business! Somedragon has a thing for MILFs, doesn't he~?" Velvet responded teasingly, crossing her arms under her chest to emphasize her expansive bosom.
"Mmh, well, growing up around your sexy ass, who can blame him, Velv?" Cadance added, tittering as she noticed the awkward walking pattern Spike had adopted in front of them.
The three arrived at the spa's sauna some minutes later, each clad in towels that only barely reached from their chests to their hips. Spike's was particularly ineffective given his taller draconic stature, allowing the two mares to get an eyeful of the half-formed erections they'd given him.
"Oh fuck yeah, he's got two...and look how big they already are~..." Velvet commented, rubbing her thick thighs together as she bit her lip. Her towel, already almost uselessly small on her voluptuous matronly body, was discarded to the floor of the sauna in short order, allowing Spike an unfiltered full-frontal view of Twilight's mother's utterly gorgeous body.
"Sun and stars...you are so beautiful it brings a tear to my eye, Velvet." Spike commented reverently, feeling light-headed as he scanned the mare up and down; from her immense, jiggling bosom to the flare of her child-bearing hips, and the eye-catching inward slope of her pubic mound. She giggled and did a twirl for the enthusiastic drake, flashing him a view of her thick MILF ass from underneath her tail. It nearly made him want to faint! "I have no idea what I've done to deserve this from you both, but I'm going to treasure this view for the rest of my life..." He said, slightly dizzy from the amount of blood rushing southward, and blushed in embarrassment as his pricks twitched and throbbed, now painfully hard from her display. He shielded them with his hands in a moment of modesty, remembering at that moment where he was and who he was in a room naked with.
Velvet grinned as she saw the evidence of his renewed enjoyment, and gestured for him to remove his hands. "No need to be shy all of a sudden, dear~! We're going to be doing a lot more than looking at each other, after all..." To emphasize her point, she pushed Spike down onto the sauna bench and knelt down on the floor in front of him, bringing her face in close to his crotch. Cadance followed suit shortly thereafter, the two of them kneeling in front of him as they stared as his immense, exotic flesh with a mix of wonder and lurid anticipation.
"Trust us, Spike...This is as much a reward for us, as it is for you~" Cadance assured him, before beginning her ministrations on his pulsing, angrily-throbbing upper cockhead. She hummed pleasantly as she worked her lips over his tip, causing Spike to dig his claws into the sauna bench from the incredible sensations.
"We get a hot, young, dragon stud~ all to ourselves for Mother's Day, and..." Velvet added, licking the edges of Spike's stretched-out cloaca in a way that made him shudder and shake.
Cadance interrupted the other mare's sentence by showcasing just how lucky Shining was to have her; shoving her head down on Spike's upper cock until the knot rubbed against her fuchsia lipstick. It sent the unprepared young dragon into a fit of shuddering and groaning as his brain went absolutely haywire.

Velvet grinned lasciviously at the hedonistic display and stared into Spike's eyes as they drifted into the back of his skull, but she continued to speak. "...And you get a once-in-a-lifetime reward for being the rock in our darling Twilight's life all these years! I'd call that a win-win, wouldn't you~?" She finished teasingly, ducking underneath Cadance's enthusiastic deepthroating to apply her own experienced mouth to Spike's lower member.
"Now...mmh...let's get you good and ready to fuck me into a stupor~" Velvet purred, engulfing the upper three-quarters of Spike's cock with her maw.
"Mmh...be honest, Spike...how many times have you fantasized about pinning me down and reaming me with those fat dicks of yours?" Velvet asked with matronly sweetness, completely at odds with her lascivious question in a way that made Spike's dicks twitch. Even from her supine position underneath Spike, she found a way to exert her feminine control over him, hotdogging his lower cock with her vulva as his upper cock ground its leaking tip into her belly.
"I'll put it this way, Velvet...I'm only into Rarity because she's the next-closest mare I've found that even comes close to you..." He admitted, causing both Velvet and Cadance's eyes to widen in surprise for a moment before hiding it behind their mask of cool maturity. Velvet's heart melted from the sentiment.
"Oh, honey...you don't have to imagine it anymore, dear...take me, you big, beautiful drake!" Velvet cried wantonly, wrapping her legs around his waist and forcing his thick, dripping dragon dicks halfway into her pussy and ass with a single clench of her leg muscles. Her hands scrabbled for purchase on the slick sauna planks as she screamed in a mixture of pain and pleasure, before she threw her arms around his body and dug her nails into his strong, scaly back.
"Fuck yes! Unnh~!" She groaned, writhing as Spike began slowly thrusting into her, inching deeper into both of her holes with slow, meaningful humps. Her eyes rolled back into her head as the drake's intense deep-dicking double-penetration slowly began to pick up speed, driving any coherent thoughts from her experienced mind. She groaned dumbly as her panting tongue drooled onto her chin, and her head lolled aimlessly as Spike's scaly hips clapped against her thick ass and thighs.
Cadance fingered herself vigorously as she watched the show from her seat opposite the mating pair, staring intently at the huge, shifting bulge protruding over halfway up Velvet's torso; the poor mare was getting utterly destroyed by Spike's huge draconic dicks, but she was willing to bet that the lascivious older mare wouldn't have wanted it any other way.
"Oh, fuck...oh, fuck...sun and stars, you're so fucking good!" Spike groaned, trading speed for power as the combined sensations of her pussy and ass clenching overwhelmed his relative inexperience. "I'm not gonna last much longer, Velv!" He warned her.
"Do it! Do it, Spike! Fucking fill me! I've needed this for so long! Give me your kirins!" Velvet screamed, thrashing about in the throes of ecstasy as the unique sensations drove her absolutely wild with pleasure and animalistic fervor.
"Rrragh! You are mine, pony! MINE!" Spike bellowed as he slammed home within his new mare one final time, completely lost to greed-lust as his massive knots popped into her holes. Velvet screamed in ecstasy as Spike buried his face in the crook of her neck and gave her a fierce mating bite, letting a gout of his dragon-flame leave a shimmering green tribal mark on her shoulder.
Muffled splurts and throbs echoed meatily through the tight confines of the sauna as the twitching couple embraced each other, the mare's womb and stomach bulging obscenely with the sheer volume of Spike's essence. She smiled a dazed, beatific smile as she gazed down upon her cum-belly, rubbing it fondly with one hand as memories of her time carrying both Shining and Twilight flashed through her head. A single tear rolled down her cheek as Spike's gift gave her a rush of motherly contentment, the likes of which she hadn't felt in over a decade and hadn't thought she would ever feel again.
Overcome with emotion, she brought one hand to the back of Spike's neck and pulled him in for a heated lover's kiss; the type of kiss she had never shared with anyone except Night Light before. Spike's long, forked tongue ran circles around her own broad one, driving her wild as he dominated her mouth just as he'd done to her loins.
A flash of guilt hit her at the thought of her husband, but it was fleeting. He had given her this present, so he'd surely known Spike would end up being the greatest lover in Equestria and claiming her as his brood-mare, right...? As Spike's spurts of scalding, tingly dragon essence petered out inside her, he gave one last buck of his hips to grind his knots and barbs against her insides. Any thoughts of Night Light were driven from her head in an instant, as the two broke away from their passionate kiss to stare into each other's eyes. "Mine." Spike growled, staring into her eyes with a look that made her already-sated loins tingle and quake.
Velvet shuddered. "Yours, Spike. All yours." She responded, motes of exhaustion creeping into her voice as the intense afterglow hit her. She whimpered as Spike pulled himself free of her, and drifted off into a content slumber on the sauna bench.
A loud moan from elsewhere in the sauna caused Spike's attention to snap to the other mature, love-hungry mare in the room. Panting and disheveled, Cadance bucked fitfully as she brought herself to yet another orgasm by her own hands, kneading her ample breasts with one hand as she fingered herself with the other.
Noticing Spike's wanton gaze, she slowed her self-ministrations to a stop, smirking at the horny drake with lidded, intoxicating eyes. "Did you enjoy the show, Princess?" Spike asked as he plodded over and took a seat near her, the question obviously rhetorical given Cadance's state.
"Mmh...I haven't seen love like that in a long time..." The mare replied, voice a lilting and seductive growl. "You really fucked up that horny cougar, didn't you, stud?"
Spike's eyes widened as she spoke. "Rrr. That I did. I think I see another horny cougar I'd like to have my way with, though." He said, right before pouncing on Cadance and pinning her to the sauna bench.
"Ooh, me, a horny cougar? You flatterer! I'm not that many years older than Twilight, you know!" Cadance replied, seemingly uncaring of the way Spike had pinned her down.
"You never did have assets like these before having Flurry, though." He commented, grabbing at her chest with both claws. They filled his palms perfectly, just the right size for him to grab while he'd be rutting her stupid within the next few moments. She moaned slightly as her firm nipples grazed his scaly palms, but held her composure. She hadn't earned the title of "Princess of Love" for nothing. "And this ass of yours could make a lesser male weep!" To emphasize his point, one of his claws shifted from her breast to one-half of her motherly flanks, spanking it harshly before giving it a firm grab.
Cadance frowned. "Spike, I'm a lot more than just a pair of tits and an ass..." She chided, frowning at him.
Spike's eyes widened as he started to backpedal, releasing her as he allowed her to sit up again. "U-uh, sorry, Cadance. Did I go too far?"
"Gotcha!" She exclaimed, giggling mischievously tackling Spike to the floor of the sauna as their roles abruptly reversed. "You're still such a gentleman after all these years, dear Spike, but also still ever-so-gullible~" She teased, wiggling her ass on his lap as she looked down at him from her suddenly advantageous position. "There's a time and place for love, and a time and place for lust, and I'd certainly say this is the latter~..."
Spike shifted underneath her, testing her strength, and grunted in surprise as he found he couldn't budge!
"You know, Spike, it's not unheard of in pony history for noble knights to have had their pick of a village's women after successfully defending it from invaders..." Cadance teased, coming within a hair's breadth of locking lips with the dragon until she sat back up, straddling his huge, slickened dragon-dicks with her thick thighs. Fatty though they may have been on the outside, their core still contained an incredible alicorn strength as they held an iron grip on his hips, preventing him from doing anything unless she allowed him to. "You've already claimed one lovely mare for your breeding hoard, noble defender of the Crystal Empire...how would you like to claim your Princess for it as well~?" She growled, teasing him mercilessly as she fanned the flames of their mutual rut-lust, bringing him in close to her and breathing heavily into his face as she locked eyes with him.
"You do me a great honor, Crystal Princess..." Spike replied, sounding reverent. With a sudden burst of draconic might that caught Cadance off guard, he bucked his hips violently upwards and pushed her off of him, before pouncing onto her so that they were belly to belly. "...I look forward to making you my next kirin-breeder shortly!" He finished, reverent tone replaced with all-consuming lust.
"Oooh, Spike~! So commanding and sure of yourself all of a sudden, hmm~?" Cadance somehow still maintained her composure, even as both of Spike's massive knotted, barbed, cum-slickened shafts ground against her cleft and taint. "Show your Princess what you've got, then, brave knight!" She moaned, wrapping her strong legs around his waist and forcing him inside her, all the way to the base, with a single thrust.
She wheezed and whimpered as her stomach bulged obscenely from the intrusion, eyes widening as her mask crumbled away for the first time since the encounter had begun. "O-o-oh! I knew they were big, but sweet Celestia and Luna! Fuck, no wonder Velvet lost her fucking mind on these! Mmph!" She moaned and groaned fitfully. Even as experienced as she was, the sensation of Spike's two barbed dragon dicks grinding against each other through the walls of her pussy and ass made stars dance across her vision.
Her eyes rolled back into her head as her pupils turned heart-shaped, tongue lolling out as she threw her head back against the floor of the sauna. Spike buried his head into her neck and took deep draws of her scent, groaning as her strong legs gave even more force to his mating press.
The princess proved to be even tighter than Velvet had been due to her younger age, which drove Spike up the wall. It had been tough to keep it together with Velvet before, but even with his stamina reinforced from having just cum moments ago, Cadance's body was simply too intoxicating to hold his orgasm at bay for very long.
"Do you want it, Cadance? Do you submit to my claim of your body, mind, and soul?" Spike growled in her ear, hugging her tightly to his chest. His lungs and muscles burned from the exertion, but he pushed past it.
"Oh, yes! Yes!" She whimpered inarticulately, squirming underneath her utterly dominant mate as her long multicolored mane tossed about.
"Yes what, Princess?" He growled, continuing to piston himself deep into her holes with dizzying speed and intensity, the muted plap of scales on fur echoing in the closed space of the sauna.
"Fill me, Spike! Make me your broodmare! Fill me with the next royal bloodline, my Prince!" She screamed, her intense love for Shining Armor subsumed into the all-consuming lust for her long-time friend's scalding-hot draconic seed.
"Rrragh! With pleasure, Princess!" He bellowed, slamming himself to the base one last time as his knots shlorped into her. He gave short, fitful thrusts as his cocks bucked and jerked inside her, before letting out a deep and satisfied growl as he felt his release arrive.
Cadance's back arched as her gut surged forward, womb completely overwhelmed by the influx of her future hybrid offspring. She groaned, low and long, interspersed by a surprised moan as Spike gave her a dragon-fire mating mark on her shoulder, to match the one he'd given Velvet.
She shuddered pleasantly as Spike's release trailed off inside her, rubbing her bloated womb against his chiseled abs in a way that made both of them shudder in ecstasy. "You are mine now, Cadance..." Spike huffed into her ear. "Not just you, but Velvet as well."
"Mmh, gods... Shiny and Night Light have no idea what they signed themselves up for..." Cadance whimpered. "No mare could resist a dragon as studly as you, Spike. Not even an alicorn who holds dominion over love itself~..."
The tightly embracing couple rolled onto their side, facing each other as Spike began to pull his members free from her abused holes.
"Mmh, yessss..." Spike hissed, gazing into Cadance's content, drowsy expression as he disengaged from her. "Happy mother's day, my new broodmares~!" He announced loudly.
"We love your gift, Spike...so generous..." Velvet groaned, having been awoken some time ago by their loud coupling. She rubbed her belly in contentment, still quite pronounced even as it slowly leaked onto the sauna bench.
"I don't know what I'm going to tell Shiny, but right now, I don't caaare...mmh..." Cadance moaned as she drifted off.
Author's Note
Happy Mother's Day, y'all! 
Figured I'd do something special for my favorite MILF and favorite Princess today~
I wrote this over yesterday and today in, like, six hours, so lemme know if there's any mistakes!
