Luster Dawn lay flat on her stomach in bed, lost in reading 'Principles of Magical Analysis,' a book she had 'borrowed' from the Canterlot library. She always hated summer breaks, so much wasted time being stuck home that she could be spending learning more from Princess Twilight. Sure, her mom gave her free reign of the School of Friendship's library when she was home, but none of the literature over there really interested her. So she always smuggled home some books on important things like magical theory and arcane sciences from Canterlot, to provide her with something to engage her brain with when she was stuck home like this.
"Luster," a voice called from a lower level of the castle, echoing through the crystal halls, "your dad's going to be home soon. Get down here so we can get his present ready."
"Whatever," she shouted back. "I'm almost done with this chapter, mom. Just give me a few more minutes and I'll be down."
"You said that an hour ago, young lady. Now march yourself down here to the entrance hall before I come up there and have to bring you down myself." her mother called.
Luster rolled her eyes and attempted to audibly sigh loud enough to carry back to her mother. She took her time marking the page she was on before hopping off her bed and stretching her back. She began to trot to where her mother waited, going as slowly as she thought she could get away with. As she entered the room and her mother came into view, Luster was stricken by the sight of her. Not that she'd ever admit that, though.
Starlight Glimmer stood awaiting her daughter's arrival, draped in most of her set of the matching outfits they'd be wearing today. All four legs were clad in dark red stockings. Around her neck was wrapped a black leather collar, from which a tag hung bearing the cutie mark of Luster's father, Sunburst. From two studs at the sides of the collar, satin ribbons hung, draped along Starlight's sides, framing her body before the met again attached to a sapphire gem that capped the plug in her mother's ass. Starlight's tail was hiked up high above her body and tied off with a thin, golden chain that connected to a third stud on her mother's collar, rendering her mom unable to cover any of her most private bits. She was fully on display to Luster, who tried her best to hide her arousal as she walked in.
"Well, it's about time you dragged yourself out of your room," Starlight proclaimed with obvious impatience at her daughter's procrastination. "Trixie and your dad will be home any minute, and you haven't even started getting dressed."
Luster's eyes drifted to her own outfit, identical to what her mother was wearing in everything but color. A dark red collar and ruby-capped butt plug, black stockings, and silver chain contrasting her mother's golden one, were the only differences. Sitting on a table nearby were two ball-gags, one black and one red, that would be the final elements of both their costumes. She blushed as she imagined the looks on Trixie's and her dad's faces as they walked in and were greeted by the sight of the two mares presenting themselves in such an outfit.
"Oh, and make sure you thank Rarity for making these outfits for us on such short notice the next time you see her. It was a very generous thing to do, so get moving and don't make all her hard work go to waste by not wearing yours," Starlight said.
"But moooommm," Luster whined, "it's embarrassing."
"Oh please, you sound just like Trixie when you whine like that. You're not showing off anything your father and Trixie haven't seen before. Just think of it as providing an accent to some of your best features." Starlight reassured her daughter as she gently rubbed against her side.
"But-"
"Now Luster, do you think Flurry Heart makes this kind of fuss when her mom dresses her up?" Starlight questioned, dragging the one mare her own age that Luster felt any personal connection into the conversation. Flurry and Luster had spent most of their childhoods in close contact, and they had grown very close as they reached their teenage years.
"No, probably not," Luster admitted.
"And she has to present herself to a whole empire. Doesn't it seem silly to make such a fuss about showing off to only two ponies?" Starlight asked as she nuzzled her face against her daughter's neck, peppering soft kisses through her fur.
"Maybe, but Flurry loves that kind of stuff. Princess Cadence probably uses this exact same argument on her when Flurry would rather spend an evening getting rutted in the guard barracks than studying magical theory, and you know it." Luster countered.
"That may be so, but it doesn't change the fact that you're wearing this for your father today," Starlight was done arguing, eyes on the clock as it drew closer to the time Trixie and her had planned to be ready. "Now turn that cute little rump toward me, hike up your tail, and let me get you dressed."
Luster knew better than to continue resisting, lest she end up wearing this get-up for the whole summer. It just wasn't fair, she thought to herself as she presented her rear to her mom. If nearly any other pony in Equestria had been her mother, Luster wouldn't have to care what they tried to make her do. She could have simply teleported them away, or turned them into a newt, or used any number of the countless spells she had in her repertoire to avoid having this argument. But no, she grumbled inwardly as she felt her mom wetly kissing her anus to prep her for the plug, she had to be born to the one unicorn in Equestria who even most alicorns would have a hard time matching in sheer magical potency. Luster could cast circles around her dad and Trixie, but she had learned early on that her mother was in an entirely different weight class. If her mom wanted Luster to do something, there was very little that could be done to escape it.
Luster let out a soft moan as she felt the butt plug slide slowly inside of her, along with the feel of her mother's magic wrapping around her neck as she popped the collar on. Luster had to admit that Rarity had done a wonderful job on the leather work, padding the inside of the collar so that it gripped around her neck tightly, while still providing enough lee way so as to not choke or chafe her. It might be kind of embarrassing, but Luster had to admit there was something about wearing it that made her feel pretty hot. She might have to save this outfit for the next time her and Flurry got together.
Luster let out a surprised yelp as Starlight levitated her into the air, bringing her thoughts back to the current moment as the black stockings slid up her legs. Her mother lowered her back to the ground as she draped the ribbons in place around her. Luster felt a firm tug at her tail as it was tied into place. She was unable to move it down, leaving her mother with an unobstructed view of how wet wearing this was making her.
"Well, well," Starlight said smirking as she examined her daughters dripping arousal, "seems like you're enjoying your outfit after all, huh?"
Luster was about to retort, but the words were lost in her throat as she felt her mom's tongue invade her. Starlight slobbered roughly over and inside her daughter's snatch, building the girl up to a much needed climax. Just as Luster felt like she was about to burst, suddenly that wonderful mouth pulled away, leaving her feeling empty and needy. She was about to yell at her mom for teasing her, but Starlight was quick to insert the red gag as soon as Luster opened her mouth. Starlight smirked teasingly at her daughter.
"Sorry dear, but I'm afraid you simply wasted too much time getting ready." Starlight teased. "Your dad and Trixie are just about here, so get into position and remember to be a good girl for daddy. This is his day, after all."
With that, Starlight hovered the other gag into her own mouth, and the two mares shared a look of lustful desire between them as they drooled hungrily around the ball gags. Then they got into position, hind quarters presented straight back toward the door as they lowered their heads to the ground, perfectly presented to whoever walked through the entrance of the castle.
Sunburst and Trixie entered the castle together. Trixie's fore-hooves were draped over Sunburst's eyes, blocking his vision of the mother and daughter duo. Once they were fully inside and she had closed and locked the door behind them, Trixie lifted her hooves up, allowing Sunburst to take in the amazing sight of Starlight and his daughter presenting themselves to him, dressed up in incredibly sexy outfits.
"Happy Father's day!" Trixie exclaimed, before planting a light kiss on his cheek. "To a great and powerful Father."
Sunburst stood speechless as he took in the sight of his gift. He stood stock still, mouth hanging open, as he processed what he was seeing. Trixie chuckled as she watched him, then noticed that there was at least one part of him not wasting any time getting ready. She placed a hoof on his hardening erection and began to stroke up and down along his shaft.
"Don't just stand there looking clueless," she spoke into his ear as she stroked him. "Go show your mares how much you love them."
"B-but, who do I start with?" asked Sunburst, worried that he might insult one of the magical dynamos dripping in front of him if he fucked the other mare first.
"Hmm, good question," Trixie said as she withdrew her hoof from his cock and tapped it under her chin, pondering an answer. She trotted up to the two presenting mares, swaying her hips and flagging her tail as Sunburst watched. She placed a hoof on each girl and began to caress their butts, slowly moving along the mares' curves. As her hooves moved down toward their more sensitive bits, Luster began to squirm, pressing herself back against the older mare's touch.
"Well, I think your daughter appears to be more eager for some relief," she proclaimed, "so the great and powerful Trixie suggests starting with her. Besides," she slapped her hoof sharply against the young mares ass, eliciting a surprised yelp form Luster, "this is Father's day. Why don't you let her show you how much she loves her father?"
Luster tried to grumble some sort of retort to Trixie's teasing, but it was lost to the gag in her mouth. Starlight chuckled as she watched her daughter try to hide her arousal behind her sarcasm. She reminder her so much of herself at that age.
Sunburst approached the dripping warmth of his daughter, casting a thankful glance to Trixie for finding a diplomatic way of making his choice. Trixie smiled back, before dipping her face behind Starlight and treating herself to her favorite meal. Just because this was Sunburst's present didn't mean that Trixie wasn't going to enjoy herself tonight too. She was, after all, just as much a part of the family as anyone else present.
As Starlight began to moan beneath Trixie's ministrations, Sunburst stepped up to Luster's rear. He leaned down and pressed his muzzle against his daughter's pussy, making her whine in need as he took a deep whiff of her familiar scent. He gave her a few teasing licks, causing her to echo her mother's moans in a delightful chorus of pleasure, before drawing his face back and preparing to enjoy his gift.
With a soft grunt of effort, he mounted the young mare and lined himself up with her. The head of his cock pushed against her welcoming heat, just barely parting her lips as he stroked it up and down her damp slit.
"Ready for me, honey?" he asked, nibbling her ear as he prepared to enter her.
Luster looked back with a needful glance, silently pleading with him to take her. Unable to voice her desire, she settled for a curt nod before turning her head back to face forward, trying to hide how deeply she was blushing at her need for her father. The normally aloof mare was not used to displaying such open desire for other ponies, and she was sure her parents and Trixie weren't going to let her live this down for the rest of the summer.
Sunburst fought back a laugh at his daughter's embarrassment as he enjoyed the feeling of flush warmth below him. Lining himself up with her welcoming pussy, he slid into the tight warmth being offered up to him. Luster gasped around the gag as she felt her dad enter her, her walls hugging his shaft as it pushed deeper inside of her.
Once he had hilted inside of her, Sunburst gave Luster a brief moment to adjust to the invading instrument before he began to fuck her. His hips thrust in and out of her velvet cavern as she clenched around him. Luster could feel his cock scraping her walls as her father's pace increased. She moaned around the gag, wanting to scream his name and beg him to fuck her faster. She'd never admit it, but her dad had always been her favorite stallion to fuck. He may not be the largest she ever had, but damn if living with Trixie and her mom all these years hadn't given him a lot of practice using what he had. He always seemed to find just the right angles and tempo to render her a wreck beneath him. Her teeth clenched around her gag as she felt the pleasure swelling inside her, trying to fight back her climax for as long as she could.
Just to Luster's right, her mom had no such compunctions letting everyone in the room know how Trixie's tongue was making her feel. As the blue unicorn buried her muzzle inside her best friend and lapped away, Starlight was emitting a incomprehensible babbling of muffled words and pleasured screams around her gag. Trixie had already coaxed out a couple orgasms from the mare, and was close to earning another as she explored the crevices presented to her, a hoof rubbing Starlight's clit as she worked. Starlight pushed her face and chest to the floor, trying to gain extra leverage to allow her to better mash her cunt against her friend's face. The experience was elevated as Trixie's tongue danced around inside of her by having the perfect angle to observe the play of emotions and pleasure dancing across her daughter's face.
Luster was doing her best to ignore the lewd noises coming from her mom, having a hard enough time trying to maintain her composure beneath her dad's skillful rutting without imagining what Trixie was doing back there to draw those noises out. Suddenly she gasped as her dad reared up and placed his hooves firmly on her flanks. His cock was able to reach even further inside of her, the head pushing just the right spots to make her scream. Luster was unable to fight back the pleasure any longer, screaming out for her father as her body clenched around him and she came wetly around his cock. Her whole body was wracked with ecstasy, but Sunburst didn't give her any time to recover as he continued to thrust into her as she tightened around him. His pace became more erratic and frantic as he pounded the mare as hard as he could.
Trixie pulled away from Starlight, causing her to softly whimper at the loss of attention. Trixie walked around the pair and made eye contact with Luster, smirking at the girl's struggle to maintain her composure as she was fucked by her dad.
"Well, well. What happened to little miss 'too-busy-studying-to-hang-out-with-my-parents' now, hmm?" Trixie teased Luster as she ran a hoof through her frazzled mane. "Why, Trixie can't seem to ever recall you looking quite so..."
Luster groaned, knowing what was coming.
"...lustful," Trixie completed the joke. Starlight and Luster both shot angry glares at her, while Sunburst's mind with too consumed with his imminent release to pay attention to the magician.
"Almost there..." Sunburst moaned, snapping Luster's attention back to the cock inside of her. Seconds later, Sunburst came inside her. Luster experienced her second orgasm of the night as she felt her womb being flooded by her father's seed. She relished the feeling of delightful fullness inside of her as her dad's cum coated her insides. Sunburst collapsed on top of her, and the two ponies lay there panting softly against one another as they recovered. Sweat and cum began pooled around them, and for a moment they lost themselves in one another's heat and the rhythm of their breathing.
Their moment was interrupted when Trixie lifted Sunburst's head to her and kissed him, her tongue slipping inside his mouth and letting him taste Starlight's flavor as it explored his mouth.
"Trixie is happy that you two seem to be bonding so well, but Trixie would also like a turn with our little Luster, so if you'd be so kind as to stop hogging her." Trixie said as she helped Sunburst back up on his hooves. Luster tried to protest as she felt his cock slipping out of her, but that damned gag was still preventing her from voicing anything but whines and moans.
"Besides," Trixie continued talking to Sunburst, "Trixie maaayyy have left a certain other mare hanging on the edge, and suggests that you might want to take care of that before she does anything drastic."
Sunburst turned his attention to Starlight, who watched the three ponies piled together while she was being ignored. Her hind legs were rubbing together as her fore-hooves were moving beneath her, trying to do finish herself what Trixie had begun. There was a hungry look of desire in her eyes that Sunburst recognized well, making his cock twitch. He figured he'd better go attend to that desire before she took matters into her own hooves. There was no telling what would happen if Starlight decided she needed to resort to using her magic to get the attention she needed. Trixie was right, hard as it was to believe.
As Sunburst and his rapidly re-hardening cock moved behind Starlight, Trixie's attention was focused on the young mare in front of her. Trixie and Luster had always gotten along well, with Trixie acting more like a cool aunt than a parent as Luster had grown up. Trixie preferred to let Starlight and Sunburst deal with the boring stuff that came with raising a filly, like discipline and education. She much preferred to focus on the fun stuff like accompanying her to shows and the park, or teaching Luster how to avoid getting caught doing things that might possibly break some rules. Plus, everyone knew that Trixie always gave the best and most powerful gifts at birthday parties and Hearth's Warming. But the most important duty Trixie had taken upon herself while Luster grew up, at least in Trixie's mind, was making sure Luster grew up with a proper understanding of sex, and all the fun a mare could have with another pony. Trixie had been Luster's first, even before Starlight or Sunburst took her, and that special bond had kept the two mares connected even as Luster had moved into those difficult adolescent years she was currently ageing through.
Trixie's eyes locked with Luster's a she leaned down and licked around the ball gag, Trixie's tongue lapping up the saliva soaking the gag and Luster's fur as it traced over the ball and the edges of her mouth.
"You look really cute in that outfit," Trixie complimented Luster, "but Trixie thinks that gag is going to have to go. After all, Trixie can think of far better uses for that cute little mouth of yours than sucking on balls."
Trixie's magic wrapped around the straps of the gag and unfastened the buckle. As the gag fell from Luster's mouth, the mare took a couple deep breaths before stretching out her jaw, pleased to have a full range of motion again. Trixie gave her a moment to adjust before flipping her over onto her back. Luster lay on her back looking straight up toward the ceiling, the view obstructed by Trixie's face looking down on her, smiling. Luster smiled back and opened her mouth to say something, but was halted by Trixie's hoof silencing her.
"No more time for talking, we'd hate for your parents to finish before Trixie even begins to play with you," Trixie spoke as she directed Luster's attention over to where her dad was pounding her mom like a feral beast. Luster knew her mom liked it rough, but she couldn't remember the last time she'd seen her dad's hips move like that. Sunburst was thrusting into her like a stallion possessed, and Starlight was slamming her hips back towards him with equal enthusiasm. Now that Luster's attention was on them, she wondered how she hadn't noticed the wet slapping noises coming from their union.
"They do seem pretty into it," Luster observed. "Do they really have to make so much noise though?"
"Well, they do seem pretty worked up," Trixie responded. "Between you and me, I don't think they've had much time with each other recently, what with having to wrap up the school year and sending all the students home. Let them have their fun together, you have more important things to attend to. Trixie didn't free your mouth up because your such a great conversationalist. Though Trixie has heard you're quite the cunning linguist."
"Ugh, just sit on my face so I don't have to listen to your lame jokes anymore," Luster grumbled.
"Very well, if you insist. Trixie will even be so kind as to clean up the mess your dad made, so Trixie hopes you're appreciative."
Saying that, Trixie strode over Luster's prone body and lowered her pussy down on the girl's face. She let out a soft moan as she felt the young mare's tongue begin to trace over her pussy lips, teasing her before dipping inside. Trixie lowered her head down to Luster's marehood, where Sunburst's cum was oozing out and pooling onto the castle floor. She started to clean the semen out of Luster's fur, slurping it up and swallowing all of Sunburst's seed. The two slipped their tongues inside each other, exploring and tasting each other as their muffled moans were lost in their partner's crotch. The pair was so occupied with their pleasure, they failed to notice that the noises coming from the other two ponies in the room had ceased.
Sunburst and Starlight, having finished their wild rutting, now stood watching over the pair of mares writhing together on the floor, their faces buried in each other's cunts. Starlight's horn lit up, casting a spell on Sunburst to refresh the stallion, allowing his flaccid and spent cock to re-harden as he watched the two sixty nine on the floor. The parents shared a mischievous look before Starlight's telekinesis wrapped around Trixie and her daughter, flipping them over so that Luster was now on top. As she lowered them back to the ground, she popped out the ruby-tipped plug in Luster's ass with a swift yank, making her daughter yelp into Trixie's pussy.
Before Trixie or Luster had a chance to question Starlight's maneuvering, Sunburst had climbed up atop his daughter again, his cock at full mast. He lined it up with the widened hole of his daughter's ass, ready to take the place of the plug Starlight had just yanked out of her. He moaned as felt Trixie's wet tongue trace along the underside of his shaft, before beginning to push forward inside of Luster's cute little butt.
The walls of her ass parted to accommodate the girth of his shaft as he slid deeper into Luster. Sunburst sighed with pleasure as he felt his daughter hug tightly around his cock, squeezing him in her warmth. Starlight stood behind him, a hoof playing with his balls and fondling his ass while she watched him sodomize their daughter. Once he was all the way inside of Luster, Starlight leaned over into his ear.
"You know, Sunny," Starlight cooed as her warm breath tickled the fur in his ear, having removed her own gag when no one was paying attention, "our little Luster has been acting pretty stuck-up since coming home from Canterlot. I think she needs her daddy to give her a good spanking to fix that attitude."
Sunburst's planted his hooves on Luster's pert butt cheeks, drawing gentle circles through her fur as he contemplated Starlight's words. He could feel Luster pushing back against him, grinding herself against his dick and Trixie's face, obviously trying to encourage him to start fucking her proper. It was true, the mare had made some snobbish comments after coming home from school. Constantly reminding everyone she spoke to that she was the star pupil of the Princess Twilight, complaining about the selection of books at the School of Friendship's library compared to the Royal Canterlot Archives, and generally isolating herself from everything excluding her reading even more than usual.
Yep, this was as good a time as any to provide a little fatherly direction to the young mare.
Sunburst began to move his cock in and out of his daughter's ass, building up to a steady rhythm as he fucked her. He could tell she was enjoying herself by the noises she was making as she buried her muzzle deeper inside of Trixie. Starlight moved beside her daughter and began to nuzzle against her, gently lapping and nipping across her body. Trixie continued to eat the young mare out, occasionally withdrawing her tongue from her snatch to give a few licks across Sunburst's balls as they swung back and forth pendulously above her. Sunburst waited until he could tell Luster was completely lost in her own pleasure, before raising one of his hooves high above his head.
*SLAP*
His hoof landed hard upon Luster's right ass cheek, causing her to yelp in surprise. She tried to raise her head up to protest the rough treatment, but Starlight pushed her head her back down to Trixie's cunt. Sunburst smirked as he maintained his rhythm fucking the mare even as he brought his other hoof down on her left cheek. Years of fucking Starlight had taught him just the right amount of force to use to make his spankings sting while not being so forceful to actually hurt the mare beneath him. His hooves reigned down on his daughter again and again against his daughter's rump as he continued to pump in and out of her. He could feel her tightening around his shaft as he continued. Luster's muffled cries of protest quickly turned back to moans as she began to wriggle her butt at her father in between slaps. Noticing the shift in attitude, Sunburst couldn't help but grin as he noted yet another way the young mare took after her mother.
Starlight noticed too and lifted her hoof from Luster's head, going back to exploring her daughter's body with it. Luster raised her head from Trixie's crotch and screamed as she came from her father and Trixie's work.
"Yes daddy!" she shouted as she gushed out over Trixie's face. Luster had never imagined that being spanked like this could feel so good, but this was definitely not going to be the last time she offered her rump up to her father for 'discipline'.
Hearing his daughter cry out for him with such wanton lust pushed Sunburst over the edge, and he came deep within her bowels. He withdrew his cock from her ass, before sliding it into Trixie's waiting mouth and letting her clean him up. Once she had finished, he collapsed back, laying flat on the cold crystal floor, his wet cock semi-hard and pointed at the ceiling.
"Well," Luster spoke as she stood up off of Trixie and cuddled against her father's side, "maybe you guys make pretty good teachers after all. I certainly learned a few new fetishes today thanks to all of you." she teased, nuzzling against Sunburst's neck and rubbing a hoof across his chest. "Seriously though, I hope you had a happy Father's day, dad."
"It was the best one yet, sweetie," Sunburst kissed her softly, their tongues dancing together as Trixie and Starlight moved toward them. Trixie pressed up against him opposite of Luster, while Starlight crawled on top of him and rested her head on his chest. Sunburst basked in the warmth radiating from his three most special mares, feeling like the luckiest stallion in Equestria.
"So," Luster broke the silence after a few minutes of laying together as a family, "can I go back upstairs to my room now? I was kind of in the middle of reading something when mom dragged me down here."
"Luster Dawn!" Starlight scolded her daughter. "Is it really too much to ask for you to spend some quality time with your family during your break?"
"Hey, if the past couple hours don't count as quality family time, then I don't know what does. Besides," she said with a smirk, "if you and dad don't like it, you're more than welcome to come upstairs and 'discipline' me further."
With that she trotted out of the room, tail still held high in the air by her collar and her hips swaying noticeably back towards the three older ponies. She turned around and offered on last wink back to them before leaving the room and turning out of sight.
"I think we may have created a monster," Sunburst groaned as he watched her go, his cock twitching against Starlight's belly as he watched his daughter's display.
"Perhaps," Trixie said, "but at least she's a sexy monster?"
"Welp, I suppose the only responsible thing to do is follow her upstairs and take her up on her offer, right?" Starlight asked, standing up and assisting her two friends back up to their hooves.
"I mean, I don't see how we can just ignore her attitude. She really hasn't left us with any other choice," Sunburst affirmed as he began to follow Luster.
"Right. You'd hardly be able to call yourselves great and powerful parents if you failed to provide proper discipline," Trixie said as she moved to join Sunburst. Starlight fell in right behind, and all three trotted up to Luster's bedroom.
The four ponies spent the rest of the night in Luster's room, before finally falling asleep together in her bed as the sun began to rise over the horizon. By the time they were done, all of them were covered in each other's cum, spit, and sweat. Luster's ass throbbed red and swollen, with Starlight's in a similar condition. Not a single mouth, ass, or cunt hadn't been fucked multiple times by the other three, and there wasn't a single inch of their bodies that hadn't been tasted by the rest.
All in all, it was the perfect way to spend Father's day together as a family.
Author's Note
Happy Father's day, everyone. I couldn't resist writing some clop about my favorite family celebrating the day, even if that family isn't strictly canon. I mean, there's nothing explicitly denying their relationship either, so whatever. Startrixburst will forever be the ship I plant my flag and die on, and Luster being Starlight and Sunburst's kid just works too well to ignore.
Also, Luster just needs more porn of her in general, written or drawn.
Anyway, thanks for reading and I hope you enjoyed it.
