Matriarchal Mating

Shining Armour came to a stop outside of the house he'd grown up in, taking a moment to admire the incredible view before him: the rose bushes his mother had been tending to as a memorial for his late father, the lilies that were standing tall and blooming brilliant, and, most gorgeous of all, his mother's giant, double-wide ass clad in tight, form-fitting black leggings tending to said garden. He took a long moment to drink in the view, hungrily devouring the sight of the seams of said leggings almost tearing as they fought for their life trying to contain all that ass.

He approached his mother, holding flowers of his own in one hand and a box of chocolates in the other, tip-toeing as silently as he could behind her. Chances are she wouldn't be able to see him approaching in her peripherals due to the size of her own rear blocking out a lot of it, so the sneak success chances on his end were nice and high. He came to a stop right behind her, barely a few centimetres away, before leaning over her frame.

"Boo!" he said in a hushed tone.

Velvet yelped in fear, the trough she held between her soft fingers flying outwards into the dirt and, even worse, rocketing up to her full height and smashing the back of her head into Shining's maw. The impact hit like a two-tonne boulder, almost sending the goliath of a stallion onto his own well-chiselled ass as he staggered backwards. Pain rocketed through his now-sore nose and his eyes screwed shut. It took ever ounce of his willpower to not drop the objects he held in his hands and even more to not accidentally crush them.

"Dear sweet Celestia, Shining, I am so sorry!" his mother yelped, whirling around and wrapping her arms around her son's broad, muscular frame as best as she could.

"I suppose I deserved that," Shining hissed, gently hugging his mother back as he felt his eyes watering. "Hi, mom."

"Hi, sweetie," she muttered back, burying her face in his chest and sighing. "Anything broken?"

"Nothing too important," he shrugged, stepping back and offering the gifts to Velvet. "I brought these for you to go with the heart attack. Sorry for missing out on last week's meet-up. I was swamped at work."

"Oh, that's quite alright," Velvet chuckled, joining her hands together and unintentionally squeezing her enormous, sweater-wrapped breasts together in a more-than eye-catching manner. "They flowers look lovely."

She took hold of the gifts, giving the bouquet a gentle sniff, sighing at the beautiful scent of them before sneezing loudly.

"You're not allergic to them, are you?" Shining asked, concern dripping from his words.

"Not that I know of," she answered playfully. "Would be one hell of a way to find out, though."

Shining smirked, finally feeling the pain in his nose dying off.

"Come on, come inside," his mother said with a gesture towards the door, making her way out of the flower garden and over to the door.

Shining's eyes stayed locked on his mother's ass as she moved, feeling himself on the verge of drooling as a pre-game warm up of blood ran down to the monster locked away in his pants. Velvet cast a knowing glance back over her shoulder, winking playfully at him in a gesture only Shining would see. She opened the door and set her gifts down on the table next to the entrance, waiting with a warm, kind smile on her face for her son to enter behind her.

As soon as the door clicked into place and Shining locked it tight, the warm smile on his mother's face melted away into the most lecherous, sexually-charged, devious smirk a mare could muster. Her entire posture changed in the blink of an eye, relaxing from an uptight, older mother who carried herself so neat and proper into a hip-cocked, breast-jutting whore.

"So... now that we're away from prying eyes..." she began, holding her arms out towards her much-larger son. "How about you come and give mommy a real greeting?"

Shining wasted no time, closing the distance between the two of them, feeling her enormous tits squeeze against his large, muscular chest as their mouths locked together. Velvet felt and tasted amazing, her tongue as soft as her namesake and her saliva magically-enchanted to be a delicious blackberry flavour, something she'd done years ago for her husband's, and now her son's, benefit. Her hands locked behind his back just as his locked onto her ass, each cheek being too big for even hands as big as Shining's were, barely able to cup half of one in his grip. Soft, warm, and ever-so-slightly toned, his fingers sunk into that beautiful backside and threatened to never come out again.

Their kiss was not quiet. It never was. Panting, gasping, almost desperate to swallow the other's tongue, they remained locked together for what felt like an eternity. Shining's cock began to swell and then began to ache, the zipper on his jeans threatening to burst as that titanic black shaft almost roared to be free. His mother could tell, feeling the button of his pants press into her pudgy stomach and almost hearing it call to her. She reached downwards, skilled hands working with trained expertise to undo her son's belt and yank his zipper down, feeling the heat of all twenty inches of her son's arm-thick phallus spring up against her stomach.

"Mhmmm..." Velvet purred into her son's maw, breaking away from his just far enough to begin lapping at his tongue. "I've missed this big fucker-"

Her hand closed around the broad tip of his shaft.

"-has he missed me?" she asked, batting her eyelashes and cocking her head to the side, allowing her long, flowing mane to fall loose over her shoulder.

"Why don't you ask him yourself?" Shining smirked, continuing to obsess over his mother's ass with his hands. "Get reacquainted."

"I suppose it's the least I can do for almost knocking you out back there," she continued. "I would ask if you want mommy to kiss it better, but I think we both have somewhere this mouth would rather be."

"You gonna get it good and wet?" Shining asked.

"Only if you make a donation..." Velvet answered, opening her mouth wider and giving the exact signal Shining needed.

Without wasting a moment, he leaned forward and spat in Velvet's waiting maw, watching the skilled slut run it around her lips before kneeling down and getting to work. She kissed the head of his cock with enough love to count as a wedding vow, using that spit-slicked sucker of hers to get to work on her favourite hobby. Her big beautiful lips pressed against the tip of his shaft, and even squished and spread out like they were, they still weren't as large as his tip. Her tongue snaked out from between those lips, already covered in enough drool to drown it at this point.

She pressed the flat of her tongue against his prick, dragging the full length of that well-trained muscle across his length and finishing it off with another, sloppier kiss. That kiss soon turned into something more, parting her beautiful lips and sliding them down the length of his cock. If she were any smaller, she'd be risking splitting her jaw. Shining's obsidian obelisk so was monstrously large that smaller species without the stretch capacity couldn't sheathe it in their mouth. His mother was 5'6 and was at the absolute smallest you could be to manage to squeeze it in.

If she were any less talented at her chosen trade, she'd be somewhat intimidated at his size. But this was a mountain she'd climbed a thousand times using a route she'd walked a thousand more. She knew her son's cock like the back of her hand and knew how to make every single nerve on every single centimetre of it sing with pleasure. She'd barely started her work when they both heard a brief vibration from Shining's phone in his pocket. He rolled his eyes, hoping and praying that it wasn't work again, and his mother dug it out and handed it to him without a word between the two.

Shining checked the notification to see what it was, and was overjoyed to see it was a text from Cadance, asking how he was getting along with his mother at the moment, as well as an attached image. The attached image was Cadance, naked as the day she was born, with her tongue buried deep into their dear sister Twilight's asshole, with a large, visible red handprint over Twilight's cutie mark. Another second went by and a text message came through.

"Lil sis was being a bit bratty about you getting to knock the dust off your mom first. Had to give her a little behavioural lesson. How're things going for you?"

Shining smirked, feeling his cock twitch with excitement over getting to see two of his favourite mares engaging in one of his favourite pastimes. He turned his attention down to his mother, watching her expertly slobber all over his length, seeing every inch of his twitching black prick dripping with delicious berry-flavoured saliva. Without missing a beat, he switched to the camera app on his phone and aimed it down at his mother.

"Pick a pose for Cadance, beautiful," he instructed.

Velvet responded immediately, throwing up a double peace sign as she lay the head of her son's cock on her tongue, panting and blushing through the gesture and looking as beautiful as can be. Shining snapped the photo, petted his mother on the head, and then rammed his cock down her gullet with so much as a warning, hilting himself in her throat. The older mare didn't even flinch at the gesture, swallowing it all down into her deepest reaches with nary an ounce of difficulty, instead cupping her son's gigantic, mango-sized balls in either hand and massaging them lovingly.

Shining sent the image over to his wife, rolling his shoulders and feeling every muscle in his body unknot as the cock sucking machine that was his beautiful mother went to work on his colossal prick. The tightness of her throat, the warmness of her insides, and the gentle squeezing of his oversized nuts were a recipe for delight if there ever was one, relaxation and sexual euphoria settling over him as he waited for his wife to respond. While waiting, he kept himself busy by fucking his mother's mouth in a nice, gentle rhythm.

He kept in-sync with her breathing, in and out exactly as she did, listening to the beautiful sounds of his mother swallowing his cock over and over again, pulling out to just before the tip and then gently pushing back inside. She never struggled, she never whined, she never asked for him to stop. She handled every inch with as much dignity and grace as a cock-loving whore like her could manage, and she looked as beautiful as a summer's day every second her son's fat prick stretched her throat out to its max. Soon his phone pinged again as a reply text from Cadance came through, swiping onto the notification and seeing what the love of his life had to say.

"Lucky bitch," the text started with, getting a smirk from Shining. "Breed that fat ass of hers and send photos."

"I'm gonna be breeding a lot more than that today," Shining messaged back with a conniving smirk.

"Oh?" his wife asked, seconds ticking by before another message came in "Ohhhh..."

Then a third seconds later.

Mmmmmm..." Cadance continued. "Wish I could be there to see that. I'm still babysitting our little mischief maker."

Another video soon came through, one of Cadance equipped with a magically-conjured cock she was using to rearrange Twilight's guts in the doggystyle position.

"You like this big dick?" Cadance asked in the video, slapping Twilight across her well-tanned ass again.

"I love it, big sis!" she moaned back, getting her tail yanked as a little present for doing so.

"Who's dick is the best in the whole world?" Cadance continued.

"Shining's!" Twilight barked out, getting a loud tut from Cadance and another slap on the ass.

"Try again. Who's dick is the best?" she repeated.

"Shining's!" came the same reply, even after another smack.

"Well, well..." Cadance smirked, picking the pace up and fucking Twilight's tight little ass. "Isn't she well-trained for big brother?"

"I love my big brother!" Twilight called out.

"Yes you do..." Cadance giggled, slapping Twilight's ass again. "I'm about to cum, Twilight. Where am I gonna blow my load?"

"In my ass!" the smaller Alicorn called back.

"And then what are you gonna do?"

"I'm gonna suck it clean," Twilight nodded, moaning the loudest she'd done so far as she felt Cadance hit her limit and bust a nut in her ass.

"Oooooghhhh..." Cadance groaned. "I've fucking missed this... give my love to Velvet, baby. See you soon!"

With that the video ended, and Shining felt his mother remove her maw from his length.

"I nearly came from just listening to that," Velvet sighed, looking down at the soaking wet patch on her leggings from where her pussy had been flooding. "Show me the video. I need to see it."

Shining did as instructed, handing his phone over to his mother and letting her start the video over. Her spare hand found its way to her cunt and her mouth latched back onto her son's dripping prick, eyes locked onto the phone screen as she hit play. She sucked in time with Cadance's thrusts in the video, syncing up perfectly and allowing the pleasure of their debaucherous little double date flow through all of them together.

"Fuck, she's got such a nice ass," Velvet commented, eyes locked onto her daughter's hole getting stretched. "She's gotten so much better at arching it... mmmphhhh..."

Shining smirked, watching drool pour from the tip of his mother's tongue as she lost herself in the video. Shining took over, stroking his length in time with his wife's thrusts on the screen, listening to the sound of her hips hitting against Twilight's fat backside along with his sister's gorgeous moans.

"She's really throwing that shit back at her..." Velvet grinned, eyes flashing with dirty desire as she continued to finger her pussy even harder. "I would've loved to see... ahhh... mmmphhhh."

All three of them came at the same time, the video of Cadance cumming in Twilight's beautiful asshole, Velvet cumming in her tight pants, and Shining cumming directly into his mother's face as she jilled herself through the orgasm. She panted, squeaked, and replayed the shot of Cadance blasting Twilight's asshole with cum over and over again, hyperfixating on that ten second loop of thick, white cum spurting out from around Cadance's impressive futa meat.

She opened her mouth without turning her head, her extended tongue giving Shining's load a landing platform to aim for as he continued to spurt his glue-thick, steaming cum all over his loving mother who was still lost in her own euphoria. The stallion continued to cum and cum until he had nothing more left, firing rope and rope of desire, lust, and adoration onto his mother's body until nearly every inch of her was covered in it.

Velvet remained in place for a long moment, eventually setting the phone down and closing her eyes. Shining cocked his head in slight confusion, never having seen his mother do anything like this before and wondering what was up with her. After a long moment of silence, he spoke up to inquire about whatever it was she was going through.

"You okay?" he asked softly. "D'you need a towel, or..."

"No, no, I'm alright," she said, taking a deep, steadying breath before placing two fingers on her cum-soaked tongue and beginning to rub them in circles. "I just want to... enjoy all of this for a bit longer."

"Right," Shining nodded, leaning back against the door and feeling his own golden glow of release begin to taper off.

A few moment ticked by as he watched his mother continue to toy with the cum that coated her body, rubbing her tongue, her tits, and even sliding her semen-stained fingers directly inside her pussy. The sight made Shining's heart skip a beat and his cock twitch violently, the latter of which being something his mother noticed. A small, wry smile spread onto her lips, almost invisible under all of the cum coating her body.

"You liked the sight of that, didn't you?" she asked, eyes flashing brightly again. "All of your thick, potent, powerful cum inside of me? Did you think about it going into my womb?"

"I...," he began, before deciding he had no reason to lie with what he wanted. "Yes."

"Do you want to breed your mother, Shining?" came the question outright.

He was silent for a long moment, letting the feeling the question sent coursing through him wash over him for just a moment longer.

"Yes," he finally answered.

"I thought as much," she smirked, standing up to her full height and pressing her breasts against her son's chest, the alabaster stallion towering a foot over his buxom mother. "Let's go get a shower, then. Your father always made a habit of breeding me under the spray. It's one sensation I've been dying to feel again."

A grin spread across Shining's face, almost reaching ear to ear. She grabbed hold of Shining's shirt, pulling him closer to her with a strength unseen in her before. Her eyes were glowing a beautiful pink, her tail twitched from side to side across her massive ass, her entire body shook with a carnal desire so powerful Shining could almost feel that aura radiating off her

"Come on then, lover," she smirked, winking playfully at her much-taller mate. "Let's make you the real man of the house."
