Best Parents Ever

"Are you sure about this, Starlight?" Trixie asked her marefriend. "I mean, of course the Great and Powerful Trixie is flattered that you'd choose me, but doesn't this kind of thing usually fall to the parents?"

"Trixie, you know Sunburst and I consider you just as important in Luster's life as either of us, and we both agreed that you'd be the best pony for her to lose her virginity to," Starlight explained.

"But, I just... I mean..." Trixie stuttered nervously before she was interrupted by Starlight gently placing a forehoof against her lips.

"Trixie, you'll do fine," Starlight reassured her as she smiled gently at her partner. "We all know that you and Luster have a special bond that she doesn't share with Sunburst and me, and that's why we think you're the best pony for the job. Besides," she continued as her smile turned teasing, "who better for a little filly to share her first time with than the greatest and most powerful mare in Equestria?"

"Well, when you put it that way," Trixie's voice gradually regained its dramatic flair as she spoke, "Trixie shall endeavor to be sure that Luster has greatest and most powerful first time any pony has ever experienced! But beware, dear Starlight, for if you're not careful, Trixie may provide Luster with such peaks of erotic satisfaction that no other pony will ever be able to match!"

"I'll take my chances, Trix," Starlight rolled her eyes at Trixie's dramatics. "Just keep in mind that your supposed to be teaching her about sex, not putting on a show, okay?"

"The Great and Powerful Trixie does not teach," Trixie stated proudly. "She provides guidance and counseling to delicate young minds, and shall do the same for her favorite filly in the world. Trixie will impart all her experience and techniques to little Luster, and provide first hoof demonstrations of all such acts."

"Right, that's called teaching," Starlight deadpanned. Trixie just glared indignantly at her, until Starlight eventually conceded. "Fine," she huffed, "call it whatever you like. Either way, I'm sure Luster will have a great time learning from you."

"If she's anything like her mother, then I'll have her screaming my name across the castle in no time," Trixie teased. "And if she's like her father, I'll have her wrapped around my hoof and begging me for more by the end."

"I just hope she's enough like her parents to share a bed with you without needing a ball-gag," Starlight murmured under her breath.

"What was that?" Trixie asked, not exactly paying attention.

"Nothing Trix," Starlight quickly said. "But, um, anyway, just make sure not to wear her out too much, alright? Remember, you'll be her first partner and first mare, but Sunburst will still need to rut her afterward to teach her about stallions. And I'll want a turn at her too, of course."

"Not a problem, Star," Trixie promised. "After all, Trixie is many things, but she's not so selfish and self-serving to deny a foal's parents a chance at making love to their child. Trixie is almost looking forward to watching you and Sunburst rut Luster as she is to do her herself."

"Thanks Trix," Starlight said, her excitement plain on her face as she imagined fucking her daughter.

"What are you worried about anyway?" Trixie asked, sounding slightly confused. "After all, both you and I have been with Sunburst enough times that I doubt there are two unicorns more practiced in stamina replenishment spells anywhere in Equestria."

"Yeah, but this is her first time, you know?" Starlight asked. "I want the experience to be about the genuine functions of her body, and it's important for her to learn her limits without the aid of magic."

"Fair enough," Trixie shrugged. "Besides, knowing Luster, she might derail the sexy times by demanding we teach her how to cast that spell," she half-joked. "But if we aren't using magic, then we'd better hope she takes after you rather than her dad in the stamina department. Otherwise, Trixie worries that the only thing we'll be helping Luster do is nap."

"I'm sure she'll be fine," Starlight proclaimed. "After all, if that little foal has the energy to make me teleport all over Ponyville chasing after her every time she tries to escape her chores, then she's got the energy to last through the three of us having fun with her."

"Very well. Then Trixie shall take her leave to prepare for tomorrow. Trixie promises to help make Luster's first time the best first time ever! And now, Trixie bids you adieu!" Trixie tossed down a smoke bomb as she finished speaking, disappearing into a puff of smoke.

Starlight coughed and waved a hoof to clear out the smoke choking her, then sighed as she watched Trixie finish climbing out of the nearby window once it had dissipated. It had been almost thirteen years since Trixie had traded being a show-pony for being a guidance counselor, but some habits had never quite left that mare.

Luster Dawn awoke and instantly hopped out of bed, more excited for her birthday than she'd ever been in her life. Admittedly, at just twelve years old, that wasn't a lot of birthdays to compare to. But the point still stood! Today was her twelfth birthday, and every colt and filly knew what happened on that day. Today was the day she got to have sex for the first time! She had every right to be excited; this was even better than learning a new spell or pulling a prank with Aunt Trixie and actually getting away with it!

Everypony knew that a foal wasn't considered fully mature until they received their cutie mark. Until a pony had discovered their destiny and found their special talent, they weren't considered adult enough to be having sex with other ponies. The exact age a foal could expect to reach that point in life varied, but generally it was around thirteen or fourteen years old. Until then, sex was considered taboo for any foal to be doing, even with other fillies and colts. Nopony wanted their young children risking becoming pregnant or getting taken advantage of before they even knew what they were supposed to do with their lives.

Of course, as Trixie had once told her, all the strictest rules have exceptions. And as much as every pony agreed that foals were too young to be having sex willy-nilly before getting their cutie mark, they also agreed that it made no sense for them to reach sexual maturity with no idea of what to do with each other's bodies. And so, a tradition had developed across Equestria that stretched back to the times before the royal sisters were even anointed upon their thrones. That tradition was that on a foal's twelfth birthday, they would spend the day with their parents -- or a trusted guardian if they didn't have parents -- being taught all about their bodies, how to pleasure other stallions and mares, and all the ins and outs of the ol' in and out.

Luster giggled to herself at that thought. Shut up, it was a good pun.

Anyway, after that first time, a foal would spend however long it took to get their cutie mark having sex exclusively with their parents, plus any herd-mates of their parents or older siblings of the foal. The idea was for the family to educate their foals on how to have sex responsibly and safely, so that by the time they were mature enough to pick their own partners, they could be trusted to make well informed decisions.

Of course, Luster didn't really care about all that boring stuff. She just wanted to have sex. And sure, maybe it was a little lame to be getting rutted by your mom and dad, but any sex was better than no sex. Or at least she had been told.

Luster would be the first to admit that she didn't know all that much about sex. Sure, she had read a lot about it, but most of what her dad's library had to say on the topic focused more on the biological and practical functions of mating rather than the fun parts. Her mom had more interesting and imaginative books on the subject to read, but those had been denied to her once mom had caught her reading them. Luster hated being denied knowledge, but their was little she could do once her mom put her hoof down on a matter. Luster might be a magical prodigy, but her mom was some kind of savant, and their was just no getting around her locking spells.

No matter how hard and often Luster tried.

Consequently, most of Luster's knowledge about sex came from second-hoof accounts of other ponies, or other pony more specifically. Luster wasn't really into the whole 'friends' thing that her parents were always going on about, especially when most foals her age were more interested in stupid things like playing games and gossiping about other foals, rather than interesting, fun stuff like arcane magic theory and the practical applications of theoretical physics theorems. The closest she ever got to a meaningful conversation was getting the Cake twins listening to her describe the poppy-seed bagel theorem, but they had quickly lost interest when they realized it wasn't about a way to bake a better bagel.

Of the few ponies around her age that she could at least stand being around, there was one filly who stood above all others when it came to sexual experience, and not just because she was literally taller than everypony else her age. Princess Flurry Heart, heir to the Crystal Empire and for whom her father served as Royal Crystaller, was a couple years older than Luster, and had received her cutie mark a little less than a year ago. She had spent the next five days and nights fucking every guard, servant, and guest staying in her palace, and hadn't slowed her pace down much since. To say Flurry enjoyed sex was like saying Luster enjoyed learning: technically true, but also a gross understatement of facts.

Listening to Flurry describe her sexual escapades over the past years, first with her parents and aunts, and then with basically every pony in her empire, always got Luster super heated. Unfortunately, until today there was little Luster could do besides rub herself off with a hoof and wait. But now, now she'd get to experience the joys of fornication all for herself. She hoped that it all lived up to her expectations, but at the very least she'd be learning something new, and when was that anything but fun?

Luster's roving thoughts came back into focus as she stood outside the bedroom that her mom, dad, and Trixie shared. Apparently it had once been the bedroom of Princess Twilight Sparkle herself, a fact that Aunt Trixie seemed to enjoy bringing up at every opportunity when talking about the activities that routinely occurred in there. Luster would never admit it, but she had spent quite a few evenings touching herself as she listened to noises coming from the other side of that door, occasionally even getting a peek inside. She found herself dripping wet as it dawned on her that from today on, she'd be free to join that wonderful chorus of sounds.

Luster Dawn took a deep breath, pushed open the door, and crossed over the first threshold to adulthood.

Luster wasn't sure what she was expecting to see when she entered the bedroom, but it certainly wasn't Trixie sprawled out on the bed with her parents no where in sight. Not that she had anything against Trixie. Honestly, she probably enjoyed spending time with her more than just about any pony else. But still... wasn't today supposed to be about sex with her parents? Trixie was a lot of things to Luster, but she wasn't her mom and she certainly wasn't her dad. She decided her best course of action was to simply ask the mare what was going on.

"Trixie? What's going on?" Luster asked. "Where's my parents? Aren't they going to fuck me today?"

"Worry not, young Luster!" Trixie proclaimed, now standing straight up on her hind-legs with her forehooves extended toward the cieling. "For you see, your parents have decided that the pony who shall take your virginity shall be no other than the Great-"

Luster silently wondered when Trixie had rigged spotlights up in here.

"-and Powerful-"

There really was no off switch for her, was there?

"Trrrrixie!" the mare finished shouting.

"Okay..." Luster's eyes continued to wander around the room as she processed what was happening. "But, um, is this, you know, legal? For you to fuck me before mom and dad do, I mean."

"Of course!" Trixie assured her. "Or at least, Trixie is pretty sure it's fine. She assumes your mom and dad made sure to double-check all that boring stuff before asking Trixie to do this."

"Alright," Luster agreed, figuring that made sense. "Mom could probably just alter everyone's memories afterward if it isn't anyway, so I guess it's fine."

"Luster Dawn!" Trixie scolded. "Starlight would never alter somepony's memories just to get out of trouble."

Luster stared accusingly back.

"...often, at least," Trixie finally admitted quietly.

Luster and Trixie both did their best to ignore the angry murmurers coming from the slightly ajar closet as they stared awkwardly at one another for a moment.

"Alright, well, whatever," Luster finally broke the silence. "You're herded with them, so I figured I'd be fucking you eventually anyway, Aunt Trix. If my parents certainly aren't anywhere around the castle, I suppose I might as well start with you," Luster said, coyly turning her gaze toward the closet. "Besides, I bet you're way better in bed than my mom anyway."

Luster and Trixie shared a mischievous smile as more indignant noises definitely didn't come from the closet.

"But of course!" Trixie affirmed, doing her best to keep from laughing. "Starlight may have certain talents in the realm of love making, but she can never hope to be the greatest nor the most powerful bedmate in this castle. Now, come here, my little filly! Come and let Trixie bring you to such heights of pleasure that you beg Trixie to never stop fucking you until the end of time!"

"You've got it, Trix!" Luster spoke, eager to start now that the initial awkwardness had passed. She trotted to the bed, only to find herself being lifted by Trixie's magic and plopped down on the mattress lying on her back. Trixie was staring hungrily between her legs, making Luster all the wetter as she squirmed beneath the older mare's gaze.

"Relax, lay back, and let the Great and Powerful Trixie show you the joys of being with another pony. Trixie shall begin by demonstrating first-hoof how an adult kisses another pony, especially a cute and sexy pony such as yourself," Trixie spoke.

Luster was giddy as the older mare leaned down and claimed her lips for herself. She felt Trixie's tongue pushing against her lips, and parted them to allow her in. Luster couldn't get over how hot, and wide, and wet the invading appendage felt as it began to explore the inside of her mouth. Gods above, what was that tongue going to feel like when it parted her lower lips if just kissing felt this good? Trixie had barely even begun to touch her, and Luster was already a sopping mess between her thighs. As the two mares' tongues began to dance and lick around each other, Luster couldn't decide whether she wanted this kiss to last forever, or for Trixie to hurry up and move on to even more pleasurable activities. In the end, she decided her best course of action was -- shocking as it was -- to actually follow Trixie's advice, lay back, and let the more experienced pony lead the way.

After what felt simultaneously like an eternity and a far too brief moment, Trixie's tongue withdrew from Luster's mouth and the blue unicorn's mouth began to pepper kisses and licks across Luster's chin, neck, and chest as it journeyed down her body. There was little pattern or sense to where Trixie planted her mouth, only that it was constantly on the move downward on the filly's body. A lick across the chin, a light nibble on her neck, soft pecks across her shoulders, sensuous laps across the fur on her chest. As Trixie continued her trek, she finally paused when she reached young Luster's undeveloped teats. Time for a new lesson.

"Pay close attention to Trixie as she pleasures your little tummy pillows, Luster. Admittedly, there isn't much here yet for Trixie to play with, but you're still young and they'll grow out with time," Trixie advised, before shifting her gaze slyly towards the door behind which two ponies were not very successfully hiding. "Unless, of course, you take after our dear, sweet Starlight. Trixie swears, that mare was almost six months pregnant with you before she just barely graduated past flat."

A very irate squawk erupted from the closet, before being stifled by what Luster assumed was her dad's hoof being planted across her mouth. She rolled her eyes. Seriously, silencing spells weren't that hard for even Sunburst's level of magic, much less her mom's. What the hay was even the point hiding if they couldn't be bothered to cast one?

Her pondering of her parents' actions was quickly forgotten when she felt Trixie begin to suckle on one of her nipples. She gasped as Trixie's tongue teased around her while her teeth lightly grazed across the tip. Whilst Trixie's payed oral attention to one teat, a hoof landed upon the other and began to move in a circular motion around the small bump. Trixie swapped back and forth between the two teats, earning many gratified moans from Luster as she worked. Trixie's mouth latched around her right tit and began to suck, while her hoof continued to trace gentle circles around the left. So far, today was definitely living up to expectations, and they hadn't even started playing with the really fun bits yet.

"Tr-Trixie, please..." Luster moaned, seeking more from her surrogate aunt. Luster's crotch was soaking wet and desperate for something to fill it. She felt like her whole body was burning up. She needed to feel Trixie's tongue and hoofs inside her, or else she feared she might lose her mind to her teasing.

Trixie released the teat she was sucking on with a wet smack and looked up at Luster's panting visage.

"Well, well. Is little Luster starting to get impatient with Trixie's lessons?" she asked. "Perhaps you think I should move on to the main lesson?"

"Yes, please," Luster pleaded.

"And just what do you think Trixie should teach you, hmm?" Trixie continued to tease the desperate filly. "Tell Trixie what you want."

"I... I want to feel you inside me. Please," Luster responded.

"Inside where?" Trixie asked innocently. She couldn't help but play with Luster a little bit. She just looked so cute writhing and panting on the bed.

"Inside my pussy, please Trixie. I need it so bad, I've never felt something this intense before," Luster begged. "Use your tongue, your hooves, your damned horn, whatever you want. Just fuck me!"

"Such language! Why, Trixie has half a mind to leave after hearing such foul demands," Trixie was trying her best to stifle a laugh as she spoke. She wondered how far she should push her teasing before giving in to Luster's demands. Maybe just a bit further. "Why don't you apologize to the Great and Powerfu- grrk!"

Trixie wasn't able to say anything more before a magical aura wrapped around her head and smashed her face into Luster's dripping wet pussy. The rest of whatever Trixie had been trying to say was muffled by the virgin cunt pressed against her mouth. Trixie merely shrugged, getting the hint, and began to lick away at Luster's slit. Inside the closet where her parents were observing the action, Starlight smiled proudly at her daughter. Here she was, Luster's first time in bed with the magician pony, and her daughter had already mastered Starlight's favorite method of shutting Trixie up.

Luster's whole world ignited in pleasure as she felt the first laps of Trixie's great and powerful tongue upon her. This was what it felt like to get eaten out? This was amazing! As Trixie's tongue began to push inside her folds, the invading instrument licking and wriggling as it entered her, Luster could feel something amazing building up inside of her. The young filly had brought herself to orgasm plenty of times before, but as the pressure within her continued to grow as Trixie continued to tongue fuck her little hole, Luster knew that this was going to blow all previous orgasms out of the water. Every muscle in her young body felt like it was contracting, a wellspring of intense pleasure was boiling over in her stomach, and every thrust and jab of Trixie's talented tongue added to the building fire within her. Her mind was no longer capable or forming words, an incoherent babble of moans and whimpers the only language she was able to voice.

And then Trixie flicked her tongue across Luster's clit.

The dam broke and all the pent up pleasure building within Luster was sent squirting over Trixie's face. Luster screamed as her climax wracked her body, her horn shooting out flares of prismatic light, her pussy clenching down around Trixie's tongue as she flooded her face with her love.

"Holy smokes, Trix," Luster managed to speak once her orgasm had abated. "That was intense. Guess now I can see why mom loves you so much."

"Hmmph. First of all, Starlight loves Trixie for her charm and personality," Trixie proclaimed, doing her best to dry her face off on the sheets and pointedly ignoring the laughter coming from the two ponies watching from the closet. "And secondly, dear Luster, that was but a quick sampling of Trixie's talented tongue. I assure you that Trixie's skill with cunnilingus extends far beyond the quick and rough tongue fucking you just experienced. But, you seemed a little pent up and Trixie thought it best to get you off before you did anything rash."

"Oh? Did you decide that before or after I had to shove your face into my snatch to get you to quit teasing me?" Luster asked.

"That may have played a factor into Trixie's decision," Trixie admitted. "But now that that's out of your system, perhaps Trixie can take her time and teach you the proper way to lick another mare? If you're not feeling worn out from that rather impressive orgasm just now."

"No, I feel fine!" Luster exclaimed. "Don't you dare stop now, Aunt Trix. Teach away."

"Very well, but Trixie thinks it time for you to start putting Trixie's lessons to practical use," Trixie swung her legs over Luster as she spoke, straddling the young unicorns face between her hind legs. Luster was provided a wonderful view of Trixie's aroused slit, droplets of her arousal sticking to her fur. Luster licked her lips in anticipation.

"This time, when Trixie licks you, you should mirror Trixie's actions with your own tongue. Do your best to pleasure Trixie's delicious and inviting snatch as she licks you, okay Luster?" Trixie asked.

"Will do, Trix," Luster responded enthusiastically, eager to get her first taste of another mare.

"Very well. Then let the great and powerful lessons continue!" Trixie shouted as she lowered her hips to Luster's face and her mouth to Luster's cunt.

Luster's vision was now consumed by Trixie's great and powerful rump. She opened her mouth and took a tentative taste of Trixie's pussy, curious to discover whether she'd like the taste or not. To her delight, she found Trixie's juices to be pretty tasty, a delicate blend of sweet and salty with a musky scent that was very much to the young mare's liking.

She moaned into the older mare's pussy as Trixie's tongue began to trace patterns across Luster's labia. Luster did her best to focus on Trixie's motions and emulate them as best she could, but it was so hard when that tongue felt so darn good against her. As Trixie once again slipped her tongue inside of her, Luster did the same. She was a little surprised by how tightly Trixie's walls gripped around her tongue. After some of the things Luster had watched her parents do to Trixie in the bedroom, she had expected there not to be much grip left inside her. Guess mares really were pretty elastic down there. Good to know.

The two mares continued to sixty-nine, lost to the outside world as they were consumed by each other. Starlight and Sunburst took this moment to exit their hiding spot and move towards the bed where their daughter was making love to their marefriend. Trixie flashed them a brief smile when she noticed their approach, before quickly returning to her work on their daughter's pussy. Luster was lost completely to the outside world, too focused on what was between Trixie's thighs to notice anything happening between them. As such, she was very surprised when she felt a second tongue begin to probe her tightly puckered anus. Trixie's legs clamped around her head, preventing her from investigating who her second invader was. She quickly found herself not caring anymore as the second tongue pushed its way inside her and began to lick inside her butt.

Sunburst stood beside the bed, slowly stroking his cock as he watched Trixie and Starlight tongue his daughter. It was quite a sight, and he was getting painfully hard watching his three mares make love to one another. He was tempted to go mount Starlight as she made out with Luster's anus, but he knew he had to wait. This was Luster's day, and he had to save his energy for her. He'd have the opportunity to be inside his daughter soon enough. For now, he just had to be patient and enjoy the spectacle.

Luster moaned needfully into Trixie's dripping slit as the dual-tongued assault on her lower holes continued. She had abandoned any attempt of following along with Trixie's movements, her technique now devolving into random licks and slurps inside Trixie's needy slit. Judging from the noises Trixie was making though, she apparently wasn't doing half bad on her own. Her suspicions were confirmed when she felt Trixie's passage tighten around her tongue, followed quickly by a flow of marejuice cascading down onto her face. Trixie stood up and she and Starlight both clambered off the bed, leaving Luster soaked with her and Trixie's cum, but positively beaming with pride. She had just given another pony an orgasm for the first time, and felt great to know she could bring somepony to that peak. She rolled over on her side, and smiled happily at the three ponies who had raised her.

"So, how'd I do?" she asked.

"Trixie gives you passing marks across the board," Trixie smiled happily back at the young mare. "Any pony who can provide Trixie such a great and powerful orgasm should be quite proud of themselves."

Luster didn't even mind when Trixie gave her mane a little tussle, to thrilled at her praise to care about such childish gestures.

"Did you have fun with your Aunt Trixie, Luster?" Starlight asked, nuzzling against her daughter's face. Obviously her mom didn't mind getting her fur soaked with Trixie's cum. She was probably pretty used to it, Luster thought.

"You bet, mom!" Luster affirmed. "That was fucking amazing!"

"Hey! Watch your language, young lady," Starlight scolded her.

"Sorry, mom," Luster meekly apologized.

"Oh, don't be such a mother, Star," Trixie interjected. "Don't listen to your mom's nagging, Trixie happens to know that Starlight swears like a fucking sailor in the bedroom, however much she might deny it."

Starlight glared at Trixie, but it quickly softened as she reflected on her words.

"Fine, I guess we can make some exceptions for the bedroom," Starlight finally conceded. "But, only when we're having sex, okay Luster? I don't want you going and developing a potty-mouth just because we let you use those words in bed."

"Alright, mom, I promise," Luster replied, happy with the compromise. She never used crass language much anyway, but it made her feel a little more grown-up knowing that she could when having sex. She flashed a grateful smile towards Trixie, who winked back with a smile of her own.

"So, do you think your up to moving onto the next set of lessons, Luster?" Sunburst now asked, his throbbing erection pointed directly toward his daughter's face. "Are you ready to suck your first dick?"

Luster quickly hopped up to her hooves, her butt excitedly wagging behind her as she eyed her dad's stallionhood up. "You bet I am, dad. I've been wondering what a dick tastes like since tasting Trixie's pussy earlier."

"Well, don't be disappointmented if he doesn't taste as wonderful as Trixie," Trixie gloated, "but Trixie will be happy to give you some pointers on how to properly suck a stallion off."

"I think I'll handle this lesson, Trix," Starlight cut in, "I've got a bit more experience with this sort of thing."

"Oh, well, if you think that best, Starlight. Trixie only thought that Luster would want to learn from the best," Trixie replied.

"I'm sure she does," Starlight growled, "which is why I'll be teaching her."

Luster and Sunburst darted their eyes back and forth between the two mares as they argued on who could give the best blowjobs. Luster could see her dad starting to get a little nervous as he watched them argue, and a devious smile slowly spread across her own face. Even at times like this, Luster couldn't resist the opportunity for a little mischief.

"Hey dad," she asked innocently, "why don't you settle this? Who's better at sucking dick, mom or aunt Trixie?"

Sunburst audibly gulped as all sets of eyes in the room immediately fell on him. This was going to take some diplomacy to diffuse.

"Well, Luster, I mean, they're both really good at it and I don't think it would be fair to say one was better or worse than the other," he replied, hoping to end this stalemate without naming one mare over the other.

"Oh come on dad," Luster whined, rolling her eyes. "I'm sure they're both good at it, but I want to make sure I'm learning from the best. So, who's the best at sucking cock here?"

"Well, I..." Sunburst stammered.

"Yes, Sunburst, who is the best?" Starlight asked.

"Trixie would also like to hear your answer, even though she thinks it's fairly obvious," Trixie spoke haughtily.

"Oh, for -- fine!" Sunburst exlaimed in exasperation. "You want to know who the best cock-sucker here is? Well, it's me. Trixie and Starlight are both fine, but the truth is that I'm better than either of them."

"Really?" Luster asked, slightly surprised by this sudden revelation.

He paused a moment, looking back and forth between the two older mares. "Well? Tell me I'm wrong."

"Well, I guess most of the stallions we've had together tend to favor your mouth," Starlight admitted.

"Trixie concedes that you might have a point," Trixie added.

"Wow, go dad!" Luster cheered. "So, where'd you learn to suck a dick?"

"Well, one of my duties as Royal Crystaller was to serve Flurry's parents when their partner wasn't available," Sunburst explained. "Princess Cadance was very thorough in her lessons regarding how best to take care of Shining Armor when she was otherwise occupied."

"Wow, I guess personal lessons from the Princess of Love herself would give you a bit of an edge," Luster mused. "But, that doesn't really help with my learning. How are you supposed to show me how to suck off a stallion when you're the only stallion available?"

"Well, like I said, both Trixie and Starlight are pretty good at it," Sunburst stated. "How about this? You let Star and Trixie teach you the basics, and once you're a little older and ready to bring some lucky stallion home, I'll blow him alongside you and show you some of the advanced techniques that Cadance taught me?"

"Oh wow, you're the best dad!" Luster proclaimed as she lunged at her father and wrapped him up in an appreciative hug. The two nuzzled lovingly together for a while, until Luster felt something stiff and pulsing rubbing against her fur. She pulled back slightly and gave her dad a sultry look. She moved a hoof to his length and began to stroke it. "I guess you're probably pretty eager to get this inside me, huh dad?"

"I've been looking forward to it for years, Luster," Sunburst admitted. "Are you ready to take me?"

"I can't wait, dad. Why don't you get on the bed and let me get my first taste of stallion?" Luster asked.

"Mmm, that sounds wonderful," Sunburst said, forelegs still wrapped around his daughter. Before he released her, he leaned forward and gave her a passionate kiss. Luster eagerly accepted his tongue as it pushed into her mouth. His kiss wasn't as aggressive as Trixie's had been, but there was something about the feel of a stallion against her as his tongue explored her mouth that made her even wetter than the kiss with Trixie had. Some primal, instinctive part of her brain was telling her to allow him to utterly dominate and breed her, and she was having a tough time focusing on anything other than the hungry heat between her legs demanding her to take his cock inside her.

The two broke apart and Sunburst lay down on his bed, hindlegs hanging over the edge and his cock pointing straight up to the ceiling. Luster took a step forward, practically drooling as her eyes focused on her treat, but she was stopped by her mother's hoof. Starlight smiled warmly at her daughter as Trixie cut in front of her and sat down between Sunburst's legs.

"I know you're eager for a taste, but hang tight for a second while we show you how to properly tend to a stallion, okay hon?" Starlight asked her daughter as she led her beside Sunburst and Trixie, giving Luster a perfect view of the coming oral action.

"Alright, so the first thing you'll see Trixie do is nuzzle your dad's balls and take a deep whiff of his scent," Starlight explained, talking Luster through the action as she watched Trixie do exactly what Starlight said. Trixie's nostrils flared as she deeply inhaled the scent of Sunburst's balls. "Now, this isn't strictly necessary for providing pleasure to your stallion, but it is a nice treat for the mare. Trust me, nothing beats the smell of an aroused stallion's musk, and it will really get you in the mood for what's coming next."

Luster observed as Trixie pulled her snout away from Sunburst's sack, then extended her tongue and dragged it up his scrotum and his shaft, leaving a trail of saliva coating the underside of his cock until she reached his head.

"Start off with licking and nuzzling his member, really show off how much you want to be down there," Starlight continued her instructions as Trixie licked and rubbed her face all along Sunburst's cock. "Sometimes you might find yourself with a stallion who you'd just like to be done with, and in those situations you're best off just taking him down your throat and letting him fuck your mouth until he's done. But, when you're with a stallion who you really like, be sure to take the time to really show him how much you love his tool. They usually appreciate the show, and it'll be more fun for you, too."

Luster could only nod in acknowledgment as she continued to stare transfixed at Trixie's blowjob. Sunburst's cock was now coated with a thin sheen of spit, and Trixie had moved up from the shaft. She was now lavishing the head of his cock with succulent licks, planting little kisses all around the tip of his dick. Luster's ears pricked up as she heard her dad moaning with pleasure as Trixie pleasured him.

"Now, see how she's moved up to the head?" Starlight asked, waiting for Luster to nod again before continuing. "That's the most sensitive part of a stallion's cock, and where you really want to focus most of your tongue work once you begin sucking him in earnest. What Trixie's doing now is teasing him to make sure he's primed to cum before she takes him in her mouth. This step isn't strictly necessary, but it's a good trick for beginners like you or for mares with weaker jaw muscles who might not be comfortable having a cock in their mouths for a prolonged period of time," Starlight explained.

"Trixie's jaw muscles are not weak!" Trixie paused her actions to protest Starlight's comment. "Trixie just doesn't like having her mouth full of cock as much as some mares," she explained, casting an indignant glare toward Starlight before returning to Sunburst's cock.

Starlight rolled her eyes. "Okay, whatever Trix," she dismissed her partner's protests. "The point is, Luster, that for a filly like you who's mouth is going to be pretty small compared to a full grown stallion's cock, it's best to limit how long you'll actually be keeping him in your mouth. The closer you can get him to cumming before taking him inside you, the easier it will be to suck him off without any discomfort. Understand?"

"Sure, I get it, mom," Luster confirmed. As eager as she was to wrap her mouth around that beautiful cock in front of her, Luster was nothing if not a diligent student. Everything Starlight was telling her was being carefully catalogued and stored within her mind for reference later. Sex and learning all at once! Could this day get any better?

"Trixie, I'm getting close," Sunburst warned.

"Okay Trix, pull off and let Luster give it a shot," Starlight ordered. Trixie did as told, making Sunburst whimper slightly at the sudden loss of attention.

"Okay, honey, now do just like you watched Trixie do. Sunburst will tap your head when he's close to cumming, and that's when I want you to take him into your mouth," Starlight instructed. "Once he's in your mouth, just suck on him and lick your tongue around the tip until he cums. Don't try to take him too deep, that will be a more advanced lesson for later."

"But..." Luster tried to protest, not wanting to delay anything for later.

"No buts, young lady," Starlight said sternly. "I'm sure you're eager to deepthroat a cock, but you need to work your way up to that. Trust me, nothing ruins the mood quicker than a mare thinking she can take a cock deeper down her throat than she's ready for and suddenly throwing up all over the stallion she's trying to pleasure. Isn't that right, Trixie?"

"Oh, that was one time, and years ago!" Trixie protested. "Are you ever going to let Trixie live that down?"

"Nope," Starlight and Sunbust responded in unison, before sharing a knowing giggle as Trixie pouted. Luster got the point.

"Okay, I'll take it easy for my first blowjob," Luster reluctantly conceded. "But you have to promise to teach me how to deepthroat a stallion eventually, okay?"

"Of course, sweetie," Starlight reassured her as she ran a hoof gently through her mane. "You'll have plenty of time to practice on your dad in order to kick that pesky gag-reflex. For now though, just take it easy and do like I told you."

"Alright," Luster said as she settled down between her father's legs. Looking at Sunburst's cock and balls from this angle, it certainly was an imposing sight for the young mare. She understood why her mom didn't want her to try to force the whole thing in her mouth. How in Equestria was this going to fit inside her other entrances?

"Elastic down there, Luster," she reminded herself. "Just remember some of the things you've seen your mom stuff inside Trixie, and she was still that tight."

No sense worrying about all that right now, anyway. She still had to suck this monster off before she worried about having it fuck her. She remembered what Trixie and Starlight had demonstrated, and began by pushing her snout against her dad's balls. She took a couple quick, hesitant sniffs before smiling and inhaling as deeply as her young lungs would allow. Sweet Celestia, that scent was intoxicating. She was no stranger to the scent of stallion musk, having caught whiffs arousal out in public plenty of times. But getting this close to the source and really immersing herself in her dad's scent, it was sending all sorts of signals to her brain triggering a level of arousal she had never experienced before. Part of her wanted to stay down here and inhale this scent forever, but she reminded herself she had a job to do.

A blowjob, hehe.

She smiled to herself as she withdrew her nose and replaced it with her tongue. She took a long, hungry lick across her dad's scrotum, delighting in the taste of him as the returned for a second lick. It was different from the taste of Trixie's pussy, saltier and somehow heavier on her tongue. She wasn't entirely sure which she preferred. She'd have to remember to do more research to determine her preference. A lot more research.

She moved her attention to the shaft, just as she had seen Trixie do. She worked her tongue up, down, and all around her dad's impressive member. She could still taste Trixie's spit all over the cock, adding her own slobber to the mix. Luster eventually made her way up to Sunburst's flare, redoubling her work as she lavished her tongue all over the head of his shaft. She noticed some fluid leaking out of the tip of his cock, and excitedly lapped it up, discovering yet another new and wonderful taste to enjoy.

"That's precum, Luster," Starlight explained, between moans. "A stallion will begin to -- hmm that's it, Trix -- drip it as they get more and more aroused."

Luster was slightly confused by the noises her mom was making, until she quickly glanced over and noticed Trixie's head buried between her legs. "Guess mom's been getting pretty horny watching me," Luster mused.

Glad to know that her mom's needs were being addressed, Luster returned her attention to her dad. She continued to lap and kiss around his flare, until she felt his hoof tapping the back of her head. That was the sign, and Luster knew it was time to take the next step. This would be the first time she ever had a stallion's cock inside of her, though certainly not the last. She took a deep breath, and then opened wide and took his cock inside her mouth.

Okay, yeah, Luster could definitely understand how this would wear on her jaw after a while. She had to stretch her mouth open much wider than was entirely comfortable in order to accommodate her dad's cock, but it was worth a little discomfort to hear him moan in pleasure as he entered her. She remembered her mom's advice, and followed it as best as she could. Limiting how deeply she took her father's cock into her mouth, she left room for her tongue to dance along the head of his shaft as she gently sucked on it. It didn't take long before she felt her dad's hooves grip the side of her head, keeping her in place on his dick. That was all the warning she received before Sunburst began to shoot off into her mouth and down her throat.

As rope after rope of thick, creamy stallion cum flooded Luster's mouth, she tried to swallow as much of the juicy reward as she could. However, Sunburst's cum was simply too much for the filly to consume, and some inevitably began to spill out her mouth and drip down her chin, neck, and chest. She was practically purring as she swallowed the delicious spunk, reveling in the gooey warmth as it traveled down her body both inside and outside of her. She might still be undecided on whether she preferred the taste of cunt or cock, but stallion cum was definitely the best. No wonder Trixie and her mom always seemed so eager to lick each other clean after Sunburst came in one of them. This tasted amazing!

When Sunburst had at last finished unloading into his daughter's mouth, he withdrew his softening cock from her maw and leaned back on the bed, panting slightly. Luster was about to ask what was next, when Starlight practically pounced on her. Luster barely had time to register what was happening, before she felt her mother's tongue dragging through her fur, greedily lapping Sunburst's cum off of her. Once Starlight had collected a mouthful of cum from Luster's fur, she initiated a wet, cum-filled kiss with her daughter. As Luster made out with the final of her three caregivers, she was caught off guard when Starlight pushed a large wad of cum into her mouth. The two mares shared Sunburst's cum between them as their tongues pushed the load back and forth between their mouths. Starlight ended the kiss by shoving his cum into Luster's mouth one last time before breaking apart, thin strands of cum still connecting the two mares as Starlight watched her daughter swallow the last of her father's cum. Starlight planted a much more chaste kiss upon Luster's forehead, just below the horn, before she turned to Sunburst.

"Ready for round two, Sunny?" Starlight asked.

"After that little display? You bet!" Sunburst exclaimed as he gestured toward his cock, once again rock hard after watching Starlight and Luster's makeout session.

"Well then, I think it's time to move on to the main event," Starlight proclaimed. "What do you think, Luster? Ready to be rutted for the first time, sweetie?"

"Are you kidding, mom? I've been waiting for this moment since my birthday last year," Luster responded, absolutely giddy about finally getting to take a cock up her pussy. In a flash, she had turned around as was presenting herself to Sunburst. "Come on, dad. What are you waiting for? Get over here and mount me!"

"Alright, alright. Rein in those sails, young lady," Starlight chided her daughter. "I know you're eager, but we have to be careful or you're just going to get hurt. Now, hold still and let me stretch you out a bit."

"What do you mean str-ohh!" Luster moaned loudly as her mother buried her snout into her pussy and began to force her tongue deep inside of Luster.

"Remember to always have someone stretch you out before taking something larger than you're used to, Luster," Trixie instructed as Starlight worked on her cunt. "As you get older, you won't have to worry too much about doing this before taking a cock in the pussy, but it's always a good idea to do before you take somepony up your butt."

"I'll -- oh!-- I'll keep that in mind, Trix," Luster managed to get out. Her mom had pulled her mouth away and had begun to insert her horn inside of Luster. It was a strange feeling, the ambient hum of magic emanating from her horn providing a bit of vibration against her walls as it stretched her open.

"Almost done there, Star?" Sunburst asked pleadingly. Luster guessed he was as eager to get his cock inside of her as she was.

"Almost," Starlight answered, having pushed her entire horn inside of Luster's passage. She twisted her head slightly to the left, causing Luster to gasp sharply as the unexpected movement inside her caught her off guard. "Yeah, I think she's as ready as she's going to be. Just go easy, alright Sunburst? She's going to be a lot tighter than anything you're used to."

"Don't worry, Star, I'm not going to do anything to hurt our little filly," Sunburst reassured Starlight. "But she's almost a grown mare now, you know she's going to have to learn to take a cock sooner or later."

"I know, I know," Starlight reluctantly agreed. "But, she's still my little girl, you know? I guess I'm just not ready to see her blossom into a young lady so soon."

"Gosh mom, do you have to sound so sappy?" Luster groaned. "I already know it tends to hurt the first time, I'm not completely oblivious. Now, less boring emotions and more fucking my cute little puss." She added a little butt wriggle toward her dad for further encouragement.

"Trixie approves of Luster's attitude," Trixie smiled as she spoke. "Now come on, Star. Come sit on Trixie's great and powerful face and let her distract you while Sunburst fucks Luster."

Starlight gave one last look at her little filly, who was about to take her first big step towards marehood, before sighing to herself and straddling Trixie's face. She had told herself for months she wasn't going to cry when the time came, but seeing her little Luster about to be claimed by a stallion for the first time was almost too much for her to bear. Plus, it was getting her really fucking hot too.

As Starlight settled her twat onto Trixie's mouth and let her get to work, Sunburst began to make his way behind Luster. Luster tried to hide the way her hindlegs were quivering in excitement. Her heart-rate was skyrocketing as she felt her dad's muzzle sniffing at her twat. She could feel his breath against her crotch, and she instinctively flagged her tail out of the way as her pussy winked hungrily at him. She needed this so bad.

She felt a moment of disappointment as Sunburst pulled his face away from her, only to shiver in anticipation as she felt his weight settle above her. She was being mounted! His body felt so hot and heavy above hers, and his cock was rubbing against her belly, nestled right between her teats and begging to be let inside her. Holy smokes, it practically reached all the way to her forelegs! There was no way she was going to fit all of that inside of her. Right? Guess there was only one way to find out. Gosh, was it getting hot in here? Maybe she ought to cast a chilling spell on the air. She should probably read more about weather manipulation when she got back to her studies -- oh Celestia, it was throbbing against her stomach-- but it was so hard to find books about that stuff in public librarys. Maybe her dad could get her access to the Crystal Empire's royal-- oh geez, dad was nibbling at her ear. Why in the world did that feel so goood??-- the Crystal Empire's royal library so she could really get -- was that the tip of his cock pushing against her pussy lips? When did that get there? This was it, wasn't it? Okay, Luster, deep breaths... don't panic, just take deep, long, thick, coc- breaths! Deep long breaths! Remember not to panic. That was important. Just be cool and don't panic. I'm not stressing, I'm not stressing, I'm not stressing.

"I'M NOT STRESSING!" Luster shouted out loudly as the other three ponies in the room turned to look at her in surprise. She blushed as she realized her outburst, trying to ignore the sounds of Trixie and Starlight cracking up with laughter from across the bed. To his credit, Sunburst managed to suppress his chuckles, instead leaning over his daughter's body to whisper into her ear.

"I know your a little anxious, but just stop overthinking what's about to happen and relax. This will feel much better for both of us if you let your muscles relax and just let me guide us, okay sweetie?" Sunburst comforted her, stroking a hoof through her mane to help calm her. "Tell you what, why don't you tell me who you plan to be your first partner once you get your cutiemark?"

"Well, Flurry invited me to the Crystal Empire whenever I'm legal so that she and I can share some of her guards together. So, I guess that's my first plan."

"Sounds like fun," Sunburst commented as he continued to stroke her mane and nuzzle at her neck, waiting for her to fully calm down. "Though, a word of fatherly advice, don't try to compete with an Alicorn in terms of endurance."

"Huh, why not? Are you saying Flurry will be better at sex than me?" demanded Luster, a little peeved all of a sudden to have her potential abilities called into doubt.

"Not better, necessarily, just that she'll have a natural advantage when it comes to lasting through multiple orgasms. Especially if she takes after Princess Cadance," Sunburst explained.

"Of course, anypony's going to look pretty impressive when it comes to endurance compared to you, dear," Starlight added, addressing Sunburst.

"Yeah, yeah, that's why unicorns have magic," Sunburst dismissed Starlight's jab. "Anyway, how are you feeling, honey? All calmed down yet?"

Luster took stock of herself. Slowly, she was able to come back to her senses, her heartbeat calming down, her muscles relaxing. All the while, the head of her father's cock rubbed against the lips of her pussy, a gentle reminder of what was about to happen.

"Okay, dad. I think I'm ready," Luster said, giving Sunburst permission to continue. She twisted her head back, allowing Sunburst to catch her mouth with his and the two shared a loving kiss as he began to slowly push his way inside of her.

"Oh, wow..." Luster moaned as Sunburst's cock slowly began to part her walls. It hurt a bit as he stretched her wider than she'd ever been stretched before, but it felt so good too. So right, having a cock inside of her. No wonder Flurry Heart loved this so much. This was almost better than studying magic!

"Oh, honey, you're so tight," Sunburst growled as he penetrated her. He had to fight his instinct to just slam into her and rut her, instead taking his time and entering her slowly in order to not hurt her too much as he fucked her.

Inch by inch, Sunburst pushed his way into his daughter's tight love hole. As he continued to pierce her, he felt her clench down around him, her body shuddering beneath him, and realized that she had just came from his entering her. Eventually he reached her cervix, having gotten about three quarters of his himself buried within her. He paused a moment, letting her walls adjust to being stretched by his stallionhood. Luster enjoyed the moment of silent intimacy with her dad. She could feel his heart beat against her back as he pressed his weight down on her. She could feel the pulse of his cock too, blood pumping through the immense member as it strained to hold open her innermost walls.

"Ready for more, Luster?" Sunburst asked her once he could feel her relaxing around him again.

"There's more?" Luster asked through a lustful haze. She could barely process that anything could feel better than she did right now.

"Oh, sweetie, you've barely even started," Starlight laughed from beside her, still grinding herself on Trixie's mouth. "You've taken your first cock, but now it's time for you to get fucked."

Hearing her mom say that word like that sent another shiver down Luster's spine. This was it, she was finally going to learn what proper sex felt like. She took one last moment to gird herself, then looked up at her father and gave him a confident nod, signalling him to proceed.

Sunburst wasted no time once Luster gave him the go, and began to pull his hips back, withdrawing himself from inside her. Just as Luster started to fear that he was pulling out entirely, she gasped as he thrust back inside of her. Again and again, he slammed into her, pounding his cock against her. His balls slapped heavily beneath her, reminding her of all the wonderful cum that was churning within. Luster didn't last long beneath her father's rutting before she felt another wave of orgasm crash through her, clenching down again around Sunburst's cock as she gushed beneath him.

Sunburst couldn't last long with his daughter hugging around him so tightly. With a final thrust forward, he pushed into her as deeply as he could go and began to empty himself out into her womb. Luster moaned as she felt her insides flood with Sunburst's semen, pumping load after load into her no-longer virgin cunt. She gave a surprised yelp as her father's legs gave out from under him, sending them both crashing down to the bed. She giggled as her dad moaned above her, and he began to lap at her neck and shoulders as he recovered. Luster could feel his cock softening inside of her, and the wet flow of cum streaming out of her lips and onto the bed. When it became apparent that he was in no rush to get off of her, she lit up her horn and lifted him up, gently setting him down beside her as she stood up.

"Huh, guess you guys weren't kidding about his endurance," Luster commented as she looked over to where her mom and Trixie were now cuddling together. Sunburst looked like he was about to fall asleep any minute, though for now his eyes were still open and watching her, a satisfied smile plastered on his face.

"You get used to it," Starlight responded dryly, "and there are some tricks and spells to keep him going longer that I'll teach you another time. But, all that aside, how'd it feel getting to have sex for the first time?"

"It was amazing, mom!" Luster excitedly replied. "I mean, I knew it would feel good, but I never imagined that it would feel that good!"

"Trixie must compliment you for holding up admirably to your first rutting," Trixie added. "Trixie was impressed how much of Sunburst you were able to fit inside, and you barely seemed troubled by the pain most fillies experience their first time. You might just be a natural at taking cock, Luster."

"Yeah, like your such an expert, Trix," Starlight stated sarcastically. "Anyway, before you start giving my daughter aspirations of being a natural-born fucktoy, why don't we get cleaned up and have a bite to eat. We can discuss what you learned today, and what you'd like to learn in the future."

"Sounds good, mom. Will dad be joining us?" Luster asked, looking back at her dad's now slumbering form. His cock was glistening with his and Luster's cum, and it was taking all of her willpower not to slurp it all off of him.

"Maybe later, for now let him rest. After all, we still have to pop your anal cherry later tonight, and you'll want him well rested for that," Starlight teased her daughter as they started to leave the bedroom.

"Mmm, and if you're anything like Starlight, you're likely to find getting that cute little rump of yours fucked even better than your pussy," Trixie added.

"Really?" Luster asked, now even more excited and curious to experience more. "Wow, I can't wait. Can I sleep with you guys every night, now?"

"Well, Trixie doesn't know about every night, but you'll certainly be welcome to join us most of the time," Trixie replied.

"Plus, the three of us will probably be spending some one on one time with you in your bed from now on too, Luster. At least until you get your cutie mark and are able to start inviting other colts and fillies your own age to sleep with you." Starlight continued.

The three mares had reached the bathroom, and together entered the luxurious bath to begin scrubbing each other clean. Living in a castle had some serious perks sometimes.

"So, what's next on my lesson plan after anal, mom?" Luster asked, full of curiosity.

"Ever the student, aren't you Luster," Starlight laughed. "Well, we'll probably spend the next few nights getting you more comfortable taking a cock inside you and refining your oral techniques. After that, we can move onto fetishes and trying to explore what you're comfortable doing."

"Fetishes?" Luster asked, sounding a little nervous. "You mean stuff like those ponies were doing in that one book by Marquis Neigh Sade that I found in your room?"

"No, nothing that extreme," Starlight comforted her. "At least, not until your comfortable with trying those things. And if you never are, then that's okay too. Remember, never let somepony else pressure you into doing something you don't want to do."

"Geez, I know mom. I'm not a little foal anymore, remember?" Luster replied, splashing a wave of water toward her mother with a hoof.

"Oh, you'll always be my little foal, Luster," Starlight said with a laugh as she dropped a large bubble of water over Luster's head. Luster yelped with shock as Trixie laughed and Starlight started to scrub the cum out of her daughter's hair.

"Fetishes don't have to be anything as extreme as some of the things your parents and Trixie do, Luster," Trixie explained. "Everypony has something that excites them more than normal, and part of being in a loving relationship is understanding what your partner likes, and making sure they're comfortable with what you like."

"So what kind of things do you mean?" Luster asked, still curious as she began to scrub a sponge through Trixie's fur.

"Well," Starlight began, "it's not like there's a categorized list of fetishes or anything, though I'm sure Princess Twilight will get around to that one of these days. But, for a few examples, I guess I can tell you all the elements of harmony's kinks."

"Oh-ho, and here is another important tradition of being a grown mare, Luster," Trixie interrupted. "Getting together with other mares and gossiping about the sex lives of others."

"Is that really a tradition, Trixie?" Luster asked innocently as Starlight rolled her eyes.

"Not just any tradition, but a great and powerful tradition!" Trixie shouted. Streams of water arched behind her and geysered up from beneath her. Luster politely clapped at the theatrics, while Starlight pointedly ignored them.

"Anyway," Starlight continued, ignoring Trixie, "let's see. Rainbow Dash is probably the most benign one, she just likes having her hooves licked and licking other ponies hooves."

"Really? That's actually kind of boring for a pony as awesome as Rainbow Dash," Luster complained. "I heard she needed to get fucked while flying at mach 3 over an active volcano with no less than four stallions rutting her at once whilst disarming a time bomb in an orphange in order to get off."

"Somepony's been talking to Scootaloo about sexual fantasies, I see," Starlight stated.

"Well, I mean, it sounded reasonable when she explained it," Luster replied meekly.

"Riiiight," Trixie replied dismissively. "Well, sorry to disappoint you and Scootaloo, but hoof-fetish is as extreme as Rainbow Crash gets in bed."

"Okay, well, what about the others?" Luster asked.

"Well, Applejack likes tying her partners up with her ropes, Twilight likes getting peed on..." Starlight continued.

"Eww, what? The Princess of Equestria likes to be peed on? Really?" Luster asked in disbelief.

"Indeed. Trixie was shocked too when she found out, but has certainly enjoyed that kink of hers since. Seeing Twilight used as Trixie's personal royal urinal is only befitting our true respective talents," Trixie confirmed Starlight's claim.

"Fluttershy really likes her animal friends. Like, really, really likes them. And Rarity is a total BDSM sub. She likes to be collared, tied up, and whipped, among other things," Starlight finished her list.

"Wait, what about Pinkie Pie," asked Luster.

"Hmm?" Starlight asked, a bit confused before remembering how young and inexperienced her daughter was. "Oh right. Well, Pinkie doesn't so much have a fetish so much as she has every fetish."

"Wait, every fetish? Really?" Luster inquired.

"The thing you'll come to realize once you're old enough is that Pinkie Pie isn't so much a sexual partner so much as she's a sexual force of nature," Starlight explained.

"What do you mean?"

"Well, remember what we were discussing earlier about alicorns having better endurance than other ponies?" Starlight began to explain.

"Yeah, sure," Luster responded. "What's that got to do with Pinkie? She's not a secret alicorn, is she?"

"No," Starlight replied. "I mean, at least, probably not? Anyway, back during Twilights coronation-"

"Her second coronation," Trixie grumbled

"Ugh, get over it, Trix. Anyway, back during Twilight's second coronation, all the princesses got together in the royal bedchambers for a celebratory orgy. Celestia, Luna, Cadance, Twilight were all there, plus Shining Armor and Pinkie Pie."

"Wait, I get Shining Armor being there, but why Pinkie Pie?" asked Luster.

"No pony questions why Pinkie is at an orgy, Luster," Trixie answered. "She just tends to be involved."

"Anyway, the orgy lasted two whole days and nights. The guards stationed outside their chambers were on a six hour rotation, and they all confirmed that the noises and sounds coming from inside never paused for even a moment. It was non-stop sex involving four alicorns, until, at last, the moans and cries trailed off and eventually ceased. And then what do you think happened?"

"I don't know?" Luster answered. "I guess they slept it off?"

"Oh, the alicorns and Shining did, yes," Starlight responded. "But Pinkie came pronking out of that room looking just the same as usual, excepting the cum and other fluids coating her. And when the guards looked inside the chambers, all the princesses were sound asleep, collapsed in a pile along with Shining Armor. And then Pinkie immediately hosted a 'Thank you for guarding the door during our orgy' orgy with all the guards, and she outlasted all of them, too!"

"Wow," was all Luster could say.

"Wow is right," Starlight affirmed. "I'm telling you Luster, that mare is some sort of ponyfication of sex itself."

"Huh," Luster pondered on this new information, before asking the important question. "So, when do I get to fuck her?"

"Not until your cutecenera, so don't go getting any crazy ideas. You may have taken your first step into adulthood, but your still too young to be having sex with anyone other than Sunburst, Trixie, or me," Starlight reminded her.

"Pfft, fine," Luster huffed. "Then, can I fuck one of you now? That story kind of got me hot," she asked Trixie and Starlight.

The two older unicorns shared a knowing look, realizing they were going to be getting this request a lot until Luster received a cutie mark.

"Tell you what, Luster," Trixie spoke with a sly grin forming on her face, "you handle making lunch for all of us, and Trixie will eat out your pussy while you prepare the food."

"Really?" Luster asked.

"Yep, and I'll eat out your butt again if you do the dishes afterward," Starlight added with a similar smirk.

"Awesome!" Luster shouted. "What are we waiting for, let's go!" she proclaimed as she hopped out of the bath and began to dry herself off.

"So, just to be clear," Trixie whispered to Starlight as they began to dry off too. "We're totally trading sexual favors with your daughter for the next year in order to get her to do all the chores around the castle, right?"

"Yeah," Starlight replied, barely able to contain her excitement. "Isn't it great?'

Trixie glanced toward the now dry Luster, who shamelessly displayed one part of her that definitely was not dry to Trixie as she left the room and headed toward the kitchen.

"Trixie agrees, Starlight. That sounds like the greatest and most powerful parenting Trixie has ever experienced," she enthusiastically agreed.

And so they followed Luster to enjoy a delicious meal prepared by her, followed by a delicious meal of her. And later that night, after Sunburst had fucked her ass and Starlight had slurped all the cum out of her hole, Luster set about changing the sheets and cleaning up the bedroom before all four ponies collapsed together in bed.

"Yep, we're pretty amazing parents," Starlight thought to herself as she cuddled up with her family and drifted off to sleep.

Author's Note

Oh hey, I've started to experiment with using emdashes in my writing. Look at those sexy, sexy horizontal lines.

Anyway, this was a really fun story to write. Its been too long since I wrote a fic featuring my favorite threesome, and I really enjoy what Luster brings to their dynamic as well. Go check out some of the other entries in the Wincest Winter of Worldbuilding Contest if you like as well. There's some really good stuff so far, so hopefully this story will put up a good showing.

Oh, by the way, if you're as much a fan of the Startrixburst ship as I am, there's a new group for us over here for you to go check out. Go join and add some more stories of the best ship in the fandom.

Hope you all enjoyed it.
