Call me Mommy

It was seven at night when Luster Dawn arrived at the castle, on a Friday night no less. Twilight had invited her pupil up to her study so that they could talk, as was their usual custom. However, tonight was different, especially for Twilight. For you see, she was in heat, and had been busy all today, and had not been able to properly attend to herself. Twilight planned to do so later tonight, but Luster’s late arrival put stop to that for now. Twilight was still adorned in her regal attire, a flowing sleeveless violet dress that faded into a white stars the closer you it got to the skirt. While Luster was adorned in a, well, a typical schoolgirl uniform, and one from her school. A white shirt over a purple blazer, with a purple skirt, red bow, and a crest over the left breast pocket for the School of Friendship.

When she questioned why she was wearing that outfit, Luster remarked that it was to help her parents with the school. Twilight did not think much of it, Starlight and Sunburst were the heads of the school, so it was feasible that they might have needed her help with something that required her wearing the uniform. The young mare probably did not want to waste time changing and just traveled as is. Once they were in her study, the mentor and apprentice began their usual talks.

It was uncanny how Luster had become so adapt at magic, but perhaps she should have expected this. After all, both her mothers were magical prodigies, not mention gifted with great magical power. Plus, one was an alicorn and the other had alicorn potential, so Luster Dawn’s magical abilities were far better than most foals her age. This eventually allowed her daughter to pass the entrance exams for Celestia’s School for Gifted Unicorns with ease as well, and it got to the point where Luster was in need of greater instruction.

Twilight would be lying if she said she was not giddy at the idea of making her daughter her apprentice. Of course, she had to try and be as unmotherly as possible. It was not as if it was the first time they have seen each other. Throughout Luster’s life, she and Sunset had made visits to see Luster here and there. They’re plan to fake Starlight being the mother worked, there were some close calls, but they managed to pull it off with none being the wiser.

Now Luster was a grown mare, training under her biological mother. It was almost hilarious how Luster thought friendship was not necessary for her to grow as a unicorn mage, she had more of her mothers in her than she realized. After six months of really living in Ponyville, and making some friends of her own, Luster had grown to see the benefits and joys of it. While she did not require a weekly report or even the occasional report like Princess Celestia did for her, Luster Dawn did make it a point to come back to Canterlot at the end of every month to talk with Twilight about the lessons she learned from the friends she made in Ponyville.

As per their usual routine, they would trade stories, with Luster retelling of her lessons learned and adventures had, and Twilight recanting her own mishaps, lessons, and adventures. Luster would laugh in a cute manner that reminded Twilight of Sunset, and Luster’s excitability reminded her of herself.

“So, Echo, my changeling friend, she was wrangled into pretending to be Garth (Griffon) by Seastar (Hippogriff), so she could tricked Rain (Yak) and Eola (Dragon) into divulging which of them had a crush on him,” said Luster.

Twilight chuckled. “Sounds like it got complicated.”

“It did, and it was. Poor Echo was getting run ragged going back and forth between those two before I had to break it up.” Luster sighed as she pinched the bridge of her nose. “Have you ever had to deal with that? Princess? Having your friends liking each other?”

Twilight hummed as she thought. “Well, honestly, Luster, not exactly. At least, not to the degree that you’re dealing with it. Now it did take a few years, but after some prodding from the rest of us, Rainbow Dash and Applejack did eventually go out, and both are now happily married. They’re the most stubborn mares I’ve ever met in my life, so you can imagine how hard it was to get them to admit they liked each other. Rainbow wanted Applejack to confess first because, and I quote, ‘I’m awesome, so why shouldn’t she be the one to ask me out?’, and Applejack said, ‘She knows where Ah live, if she wants to mare up and ask me out proper, Ah’m waitin’ right here.’ It was a nightmare…”

Luster chuckled at the idea of seeing Mrs. Applejack and Mrs. Rainbow Dash stubbornly wanting the other to ask the other out. Nowadays, when Luster would visit them, they were stubborn, sure, but their stubborn streaks often ended within a couple of minutes before they compromised. “How long did it take before they finally did go out?”

“Two. Whole. Years! Most of us were tearing our manes out! And it didn’t help that they were just giving each other these longing glances whenever we were just hanging out, or whenever we had to go on a mission together! We know you two like each other, so just kiss and do something about it already!” Twilight grossed as she slumped in her seat. “I swear to Celestia, if we had to go through one more year of that, I was about to have Cadance come down from the Crystal Empire and use her magic to finally make those two confess.”

“Glad it didn’t end up that way, Princess.”

“You and me both.”

Twilight sat back up in her chair and said, “Well then, what about you, Luster? Has anypony or anycreature caught your eye?”

Luster hummed as she thought about her answer. “Well, somepony has, actually.”

Twilight blinked. Wait, so Luster does like somepony?! Oh my, well, Starlight has given her “the talk” already, so there’s really no need to rehash that. Okay, Twilight, be cool. Don’t act like a mother right now, just act as her mentor. “Oh, really? Tell me about them then.”

“Well, it’s a mare.”

Seems that’s hereditary for us.

“She’s really beautiful, and strong.”

Sounds like she’s got my taste in mares.

“She’s also a bit older than me.”

Twilight paused. “Wait, how old?”

Luster blushed as she admitted, “A couple…decades older.”

Twilight’s right eye twitched. She’s in love with an older mare who’s twice her age?! Oh no…what if they’re just using her?! “Uh, ahem, Luster Dawn, this older mare do you trust her?”

“With my life actually,” said Luster with zero hesitation.

Oh my… “And you don’t think she’s taking advantage of you? I’m not saying she’s a bad mare, but older ponies like that…well…sometimes they just like to have a young mare on their shoulder to play with,” said Twilight.

Luster shook her head calmly. “I can imagine why you’d think that, Princess. But no, she isn’t like that. She’s kind, knowledgeable, funny, beautiful, and has the warmest smile. I honestly really can’t stop thinking about her…Even at night.”

Oh no, Luster, please don’t say that to me right now.

“I can’t help but imagine the kind of things I could do with her. Even though she’s older, I get the sense that she’d like to be dominated by a younger mare.”

Twilight gulped, rubbing her thighs together under her desk to try and relieve the tension. Her heat was starting to get to her as she looked upon Luster Dawn. Her daughter had grown into quite the attractive mare, an hourglass figure, a bountiful set of breasts that rivaled her other mother, Sunset. Wide hips, and just enough body fat so as not to be too skinny or too fat, and just the right amount of lean muscle to even her out. Twilight had to admit, she was the perfect amalgamation of both her own and Sunset’s best physical traits rolled into one hot young mare.

The alicorn mare shook her head a little. It was Shining Armor all over again, her heat was affecting her mind, making her think sexy, perverted thoughts about someone related to her. Although this mare before her was biologically her daughter, she had not spent as much time as Starlight has with her. While they shared a bond, it was not completely the bond of a mother and child, which gave Twilight’s mind a kind of mental loophole to allow her body to react this way and think thoughts about what Luster Dawn looked like naked. Granted she had helped to bathe this mare before her when she was younger, but when she became a teenager, she had never again saw her daughter naked, so she could only imagine what Luster looked like now, grown up, without her clothing.

“Princess?”

“Y-Yes, Luster?”

“If you had a marefriend, or a lover in general, what would you want them to do for you?” Luster asked.

Twilight fidgeted in place as she retorted, “U-Uh could you elaborate for me?”

“I mean, sexually,” Luster clarified. “Sorry, that’s a bit personal. Forget I asked.”

“Uh…well…” Twilight answered. “We’re both adults here, I don’t see a reason why we can’t have an adult conversation. So long as you’re comfortable with talking about such things, Luster.”

Luster Dawn smiled broadly and replied, “Of course I am, if it’s you, Princess, I’m comfortable with anything you want to talk about or do.”

If Twilight was not so idle brained with her heat, she might have found that last part of her sentence a curious thing to add on, but right now that was not the case. “Well…I um…As far as what I would want my partner to do in bed…I wouldn’t mind if they took the lead. I’ve realized I have a bit of a submissive mindset when engage in intercourse. There’s…There’s just something arousing about allowing another pony to take command of me, and use me to fulfill their desires…”

Luster leaned closer to the desk, allowing her ample bosom to press against Twilight’s desk. The mare before her had her collar undone a bit, granting Twilight a view of the mare’s cleavage. “Oh, so you like a dominate partner, and you like being used? That’s quite a kinky thing to like, Princess.”

“T-T-That’s not to say I can’t be dominate when I want to be! I-I just prefer to be in a submissive role…” Twilight sighed. “I know how bad that sounds, the Princess of Equestria, the most powerful mare in the land secretly wants somepony to use her like a cheap slut in bed…”

Luster’s eyes became half lidded as she remarked, “No, I actually get it, Princess. You are the most powerful mare in the land, politically and magically. You’re a tall, beautiful, and – if I may be so bold to say – sexy mare. Some ponies would feel intimidated by you, some might even think that you’d take complete control of them if they were to sleep with you.”

Twilight rubbed her right arm. “I have seen the…ahem…fan stories of ponies seeing me that way.”

Luster got up and reached to her mentor’s hand and gently took it into her own. “But that’s not what you want. It’s because you have so much power, so much control, that you want to let go and let someone control you. To forget that you’re a Princess for one night and have somepony treat you like any mare one would pick up off the street. Do you want to be treated like that in a relationship? No. But sexually, that’s different.”

Twilight could feel the warmth of Luster’s hand radiating up her arm, making her pulse quicken and her loins burn even more. The fact that this mare was her daughter was quickly leaving her mind, but she managed to hold onto that, if she could keep ahold of that undeniable fact that Luster Dawn was her daughter, then she could control herself. Although, why did it feel as if the direction of this conversation was skewing towards something?

“W-Well, what about you, Luster, what would you do if you had a partner?” Twilight asked.

“Hmmm…well, for instance.” Luster got up out of her seat and began walking around the desk. “If the mare I liked was setting across from me, I’d slowly approach her, like this.”

Twilight gulped audibly as she watched her daughter make her way around her desk and was now at her right side. Luster then used her magic to pull out Twilight’s chair, much to her dismay, and turned her around so that Twilight was facing Luster. The pink unicorn mare kept walking towards Twilight, and before Twilight could possibly voice any kind of opposition, Luster sat right on Twilight’s lap, straddling her mentor as she gazed at her with those golden eyes full of wanting and lust.

“Then I’d sit on her lap, like so. And then I’d give her a little peek,” said Luster.

The pink unicorn mare grabbed either side of her skirt and raised it up to show Twilight what was underneath.

“L-L-Luster! You’re not wearing any panties!” Twilight gasped.

“Any underwear, to be honest, Princess,” Luster admitted.

“W-Why?!”

“Because, well, I’d imagine it would excite the mare I love. Knowing that I was ready to go, and very willing to bend her over.” Luster’s voice was like honey in Twilight’s ears, and Luster could see that this was having an effect on her teacher. “You’ve seen me grow up, Princess. But I don’t think you’ve gotten the chance to see all of me since I was a filly.”

“N-No…I haven’t…” Twilight admitted.

Luster smirked as her horn lit up, with a flash of magical light, her top and blazer was removed, allowing Twilight to see her apprentice’s breasts jiggle in front of her. The young mare in her lap raised her hands and cupped both of her D-cup breasts, bringing them close together before releasing them and raising herself up so that they were now in Twilight’s field of vision.

“Go on, Princess, I know you want to,” said Luster in husky voice.

Twilight knew she should not do this, hell, she should have pushed Luster off by now and told her to never do something like this again. There were so many reasons why she should not indulge in this, chief among them being their blood relation, and the fact that Luster was literally seducing her biological mother without knowing it.

But…

Just…Just little wouldn’t be too bad, right…? I-I-It’s not as if I’m going completely over the line…It’s just her breasts…I mean…she did nurse on my breast milk. Granted it was after having it pumped out of me so it could be bottle fed to her…but still…it’s just a reversal. Yeah…

Twilight licked her lips as she opened her mouth and latched onto Luster’s left tit, moaning as she sucked on it. Taking her time and relishing the taste of her daughter’s nipple in her mouth.

“Hmm, that’s it, Princess, really enjoy yourself,” Luster commanded as she put her left hand behind Twilight’s head and pressed her head harder against her chest.

Twilight’s hands came off the armrests and found themselves on Luster’s back. Luster continued to stare down at her mentor with lust filled eyes, relishing the view of this beautiful and powerful mare losing herself in sucking from her bosom. That’s when Luster grabbed a bit of Twilight’s mane and pulled back, forcing the older mare to stop.

“Okay, that’s enough now.”

Luster lowered herself until she was at eye level with Twilight. She moved forward and crashed her lips against the alicorn mare’s, making Twilight’s eyes fly open as she felt her daughter’s tongue invade her mouth. Twilight’s head was awash in a sea of ecstasy at the moment, rationality was swept into the undertow, allowing only a mare in heat to be in control.

Twilight’s eyes went shut as she returned the kiss with as much passion as Luster. Her hands began to explore her daughter’s body like never before, feeling the curve of her back with her right hand as she let it drift further down. She felt Luster’s silky tail, and then her dock, and underneath that she felt the surface of her ass, soft with just a bit of firmness. Twilight could not help but reminisce about the last time she had held Luster while naked, it was back when she but a five-year-old filly, and she was babysitting her. She gave Luster a bath and got in with her, rubbing suds into the filly’s mane and tail, and cleaning her fur, all while said little filly would play around with her bath toys and smile up at her. Now that same filly, or rather, young mare, was sitting on her lap, kissing her.

Twilight’s left hand was exploring Luster’s front, feeling her breasts, and then going down again over her taut stomach and stopping just at the waistband of her skirt. She decided to stop there, letting her hand drift back to Luster’s breasts, so long as she did not cross that line, it was okay. It was not complete incest so long as she did not touch Luster down there, this was just…something else. Twilight did not have the words for it, refusing to label it as incest, doing every kind of mental gymnastics she could to not call this what it was.

Luster made slightly disappointed groan as she broke their kiss and looked at Twilight. “C’mon, you were so close, why didn’t you go further?”

“W-What?” Twilight asked in a daze.

“You’re hand was almost at my pussy, but you stopped and went back up. I’ve gone panty-less this whole time just so you could touch me down there, but I guess you really do need a partner who can treat you like the slutty princess you are,” said Luster.

“L-Luster, listen–”

“No!” Luster pushed Twilight’s hands away and got up from her lap as she stood before her, arms crossed. “I can tell you want this, you’re just afraid to let yourself go. But I know what you want, Princess. I’ve always known, and I’m here to tell you it’s okay! It’s okay to be in love with me, I’m in love with you, too!”

Twilight’s right eye twitched. “Excuse me…?”

Luster Dawn sighed in frustration. “C’mon, you don’t think I haven’t noticed. You’re glances, your touches, our private lessons, and out of all the gifted students in the school, you chose me to be your apprentice.”

“I chose you because you’re highly gifted, and very intelligent!” Twilight retorted.

“Yes, and that worked out in your favor. But it’s fine, I know you’ve wanted me since I was a filly. But you couldn’t do anything because I was a filly. But I’m not a filly anymore, Princess.” Luster struck a sexy pose, putting her arms up over her head and pushing her chest out as she widened her stance. “I’m a grown mare, now. A grown mare who has needs and wants to fulfill them with the mare she’s come to respect and love. The mare who has been waiting for so long and denying herself.”

Twilight could not believe what she was hearing, Luster was interpreting their interactions as unrequited love. She should have seen this coming; Twilight had tried to her best not to act too motherly around Luster, but sometimes she could not help it and did do those things that Luster said she did, but not out of a lustful want, but out of motherly love. However, to Luster, who did not know their true relation, it translated as a wanting, and in some twisted way, Luster’s feelings towards Twilight, the feelings that a daughter should have for her mother, were warped to believe it to be romantic love rather than familial.

“Luster…you need to listen to me, I’m being serious right now, we cannot do this,” said Twilight.

“Why not?” Luster asked.

“Because…! I’m your teacher, and you’re my student! You’re…t-the daughter of my former apprentice, I’ve watched you grow up, I’m your godmare as for Celestia’s sake!” she argued.

“And yet…” Luster’s horn glowed, and within seconds her magical aura ripped Twilight’s dress down the middle, revealing her breasts and wet panties. “You’re looking very aroused there, Princess.”

Twilight crossed her legs and draped her left arm over her breasts. “Luster Dawn! This is going to far!”

Luster advanced on Twilight, the older alicorn shot up to try and fight back, but Luster managed to cast another spell the cleared the desk and forced Twilight to turn around. With another flash of magic, Twilight found herself bent over her desk, legs spread, and tail raised. Before the alicorn mare could counter, Luster was on top of her, pressing her chest against Twilight’s back as her right hand moved her panties aside. Twilight let out a stifled gasp as she felt two of Luster’s fingers dive deep into sopping wet pussy.

“L-Luster…!”

“Shh, I’ve got you Princess,” Luster cooed.

Her fingers started to move swiftly in and out of Twilight’s cunt, making the older mare grit her teeth and ball up her hands into fists as she tried not to give into this feeling. She had not had the chance to attend to herself all day, and with her heat only making the situation worse, Twilight knew that her self-control and willpower was eroding faster with each pump of her daughter’s fingers. Without knowing, her hips gave an involuntary buck, pushing Luster’s fingers further in, wanting them to go further.

“Oh, you definitely like this, huh, Princess? Being bent over your desk by a mare younger than you. Your own apprentice.”

“L-Luster…y-you need to…stop…!” Twilight pleaded between moans.

“Cum for me, Princess, and then tell me if you want me stop afterwards…”

Luster increased the pace of her finger fucking, causing Twilight’s snatch to drip more of her arousal onto the wooden floor below. Her breathes started to quicken and wings flared, she was close, she was so close that it was not even funny. Luster decided to bring it to an end as she used her thumb to play with Twilight’s clit, bringing her mentor to climax.

“LUSSSTTEEAAAAAAAAAAAAHHHH~!!!” Twilight moaned into the room as she cummed hard, gushing her love juices all over Luster’s right hand and onto the floor. Some of it ran down Twilight’s thighs and pooled onto the floor.

Luster released Twilight, letting her mentor huff and pant. “Okay, Princess, now, tell me you want me to stop.”

There was no way she could now, masturbating while in heat did nothing to alleviate the itch in her crotch, it was a known fact that masturbating only made a mare’s heat worse. And Twilight’s sanity was barely hanging on by a thread before, now it was a shred of a thread.

Luster could tell that Twilight was needing another push, but she seemed to be more compliant than earlier. “Princess, let’s move this into your bedchambers. I want to rut you like a proper slut.”

Twilight’s mind flashed back to days long past, back to when she and Sunset had sex. Her lover spoke to her in much the same way, ordering her around like a whore. Somehow, Luster spoke with the same authority as Sunset. It was not a mystery why, Sunset was Luster’s biological mother as well, so some things of Sunset were bound to be in Luster as well. However, Twilight was not expecting it be Sunset’s domineering presence when engaging in sexual activities. The heat and combined nostalgia made Twilight pick herself up off the desk and open the doors to her bedroom.

Once both mares were inside, Luster closed the doors behind them. “Good, now, lay down on the bed.”

Twilight did not speak a word as she did what Luster told her.

“Oh, and take everything off, a slut doesn’t need a crown, regalia, or any clothes really,” said Luster.

The degrading way that she spoke to her, her own mother, why did it make Twilight shiver with delight? She did as was ordered, removing the remnants of her dress and letting it fall to the floor. Twilight took off her tiara, her necklace, and wristbands, letting them clank onto the floor with the rest of her garments. Now completely naked, the royal mare got on her hands and knees as she crawled onto the bed, stopping in the middle of the huge mattress, and turning over so that she was lying on her back.

Luster smiled lustfully as she started to make her way towards her mare. The young mare removed her skirt and crawled alongside Twilight’s right. Once she was near Twilight’s head, Luster turned around so that she was looking down at Twilight from the opposite angle. She briefly smirked at Twilight before crawling forward over Twilight’s body and resting herself atop her mentor. Granting Twilight a perfect view of the young mare’s pussy, while Luster got a good view of Twilight’s.

“Go on, Princess, this is what you wanted. This pussy has been waiting for you for twenty whole years. Nopony, stallion or mare, has touched me there, has done anything to me. I’ve been saving it especially for you,” said Luster.

Twilight could smell her daughter’s arousal, it was heady, sweet, and made her head spin. Luster was not in heat, but she was certainly very aroused and very much ready to have sex. This was only compounding the problem as Twilight’s heat was already idling her brain, and now adding in Luster’s pheromones on top of everything else.

“Well, dig in whenever you want, I’ll be helping myself.”

WAIT NO!

It was too late, Luster buried her muzzle into Twilight’s snatch, parting her pussy lips as she pierced Twilight’s love tunnel with her tongue. Twilight threw her head back and released a lustful moan into the room, gripping the sheets hard as she felt her daughter’s tongue explore her inner depths.

NO! Luster! Don’t! I gave birth to you from there! You came from there! You shouldn’t be licking it! OH, CELESTIA HELP ME WHY DOES KNOWING THAT MAKE IT FEEL SO GOOD?!

Twilight looked back down and saw Luster’s pussy still in front of her, still waiting for attention, glistening with anticipation. Luster crossed the line without knowing it, but Twilight still had a chance, she still had some wherewithal to keep herself from crossing that forbidden line. However, Luster was tired of waiting and scooted her ass back, pushing her pussy closer to Twilight’s muzzle, enough that she could feel the older mare’s quickening breathes upon her labia. Yet still, Twilight’s resolve did not break.

Okay, this is getting annoying, thought Luster.

She pried herself from Twilight’s pussy and turned her head to say, “I know it’s probably been awhile since you’ve been with a pony, but I would’ve thought a slut would still remember how to properly eat a mare. Guess I’ll need to help you a little.”

Luster’s horn glowed again, and before Twilight knew it, her face was shoved right into her daughter’s cunt. Luster’s love juices were now on Twilight’s muzzle, her daughter’s scent permeated her nostrils, and just like that, that shred of a thread snapped.

Twilight raised her hands up and brought them onto either side of Luster’s ass as she began to eat out the young mare in earnest. Luster moaned in delight at finally having her mentor eating her marehood. The young mare returned to her own meal as she dove back into Twilight’s pussy. The room was filled with the sounds of two lusting mares, slurping and licking each other’s inner walls, flicking the other’s love buttons, and in Luster’s case, gently using her teeth to pull on Twilight’s labia.

Oh, give me a break, she even uses her teeth the same way Sunset does! I can’t anymore…I just can’t! I’m sorry, Sunset, Sunburst, Starlight! I can’t hold back anymore, I want this! I want to be fucked by own daughter!

Luster could tell that Twilight was close, again, and so was she. Twilight continued to tongue her daughter’s pussy, pushing her tongue as far it would go, she wanted to explore the most intimate parts of her daughter, the parts that she would never dare to do such lewd things to, but now she was. And Luster, her daughter, reaching deep into her marehood, the very place that she came from. The idea of it, no, the act of it, was enough to push Twilight over the edge as she came hard, squirting into Luster’s mouth. At the same time, Luster could feel Twilight’s moans, the vibrations set her off, making the young mare squirt as well.

When it was over, Twilight’s face was covered in her daughter’s mare cum, and Luster’s muzzle was covered in her mother’s.

She…She cums like I do…I can’t believe it…I got to see my own daughter orgasm right in front of me…I…I even swallowed it…

Luster wiped her mouth as best she could as she got off of Twilight. “Now that’s what I’m talking about. Now I’m going to make you my mare, Princess.”

“W-what do you mean…?” Twilight asked.

“You’ll see.”

Luster turned around so that she was now facing the right way. She crawled down and pried Twilight’s legs apart, and that’s when her horn glowed. Magical energy coalesced at Luster’s crotch, and within a few seconds she created a cock, a girthy, and long one at that.

Twilight’s eyes bulged when she saw the phallus her daughter created. “L-Luster, you’re not going to put that in my marehood, are you?!”

“I just said I’m going to make you my mare, how else would I fuck a slut?” Luster asked.

“N-No! You can’t! U-Use my tailhole! Please! Anal sex! Just not there! Not right now!” Twilight begged.

Luster leaned forward, making her picker rub against Twilight’s cunny and causing the older mare to hiss with pleasure. “The more you tell me not to fuck your pussy, only makes me want to that much more.”

“Luster, you don’t understand! I’m – AAAAAAAAAAAAAHHHH~”

Luster sank her stallionhood deep into Twilight’s pussy, burying her cock up to the hilt. The young mare shivered in delight from the tightness and warmth of her mentor’s inner walls, and for some strange reason, a strong sense of nostalgia had come over her. Like she had felt this warmth and tightness around her once before. She could not possibly figure out how or why, she’s never had sex with any other mare, and this was her first-time fucking Princess Twilight. So why did it feel so familiar to her? Luster decided to push that feeling aside for now and just revel in the feeling of finally being inside of the mare she fell for.

Twilight did not have the words describe what was happening to her right now. Her own daughter just penetrated her, she was back inside of her, as wrong it was, Twilight was getting a nostalgic feeling as well, remembering those eleven months when she carried Luster inside of her womb, only to now have that same foal’s dick knock against her cervix as if wanting to come back inside.

Luster, after making sure she was not going to cum right away, started rocking her hips back and forth. With each successful thrust, Luster increased her speed. The bed began to shake as Luster’s thrust grew in intensity and speed, making Twilight’s and her breasts jiggle from each contact made. The rhythmic sounds of flesh slapping against each other added to the symphony of moaning from Twilight and grunting from Luster. At this point, Twilight was gone, she was now just a whore of a mare, her heat was finally getting what it wanted, a cock inside her, and soon a big helping of thick cum to put out the fire in her loins.

Luster released Twilight’s legs, letting them fall to the sides as she leaned forward and shortened the distance between her dick and Twilight’s pussy, switching to rapid thrusts as she felt her orgasm rising. Luster looked at her mentor’s face, tongue lolling out of her mouth, a fucked silly smile upon her face, and eyes threatening to roll over into her head at any moment. This was better than she had imagined, and she was the only mare who would get to see the Princess like this, only her.

“Do you like this?!” Luster asked. “Do you like getting fucked by your own apprentice?!”

“Yes! I love getting fucked by my apprentice!”

“That’s ‘cause you’re nothing but a fucking slut, right?!”

“I’m a slut! I’m a slutty mare who loves spreading her legs for anypony!” Twilight belted.

Luster, spurred on by Twilight’s admission, pounded her harder. With each thrust Twilight grunted, feeling the vibrations up into the base of her skull and driving her further into ecstasy.

“L-Luster…P-Please call me…mommy…!”

“What?” Luster asked.

“Call me mommy…! Please!”

Luster did not know her mentor was this kinky, but she liked it. “Okay, do you like this, mommy?! Do like your little girl fucking you?!”

“OH CELESTIA, YES! FUCK MOMMY GOOD! FUCK ME LIKE YOUR MOTHER!” Twilight yelled.

Luster pulled out of Twilight, and then forced the older mare to turn over. Twilight understood what she wanted and got on all fours. Once she had, Luster wasted little time and resumed her mating, rutting Twilight like the mare in heat that she was. Luster managed to work her right arm up and pressed her hand against the back of Twilight’s head, forcing Twilight’s head into the sheets and her ass to rise higher as Luster pounded away with wanton abandon.

“I’m almost there! Fuck, I’m about to cum!” Luster warned.

“CUM INSIDE ME! CUM INSIDE MOMMY, PLEASE! I WANT YOUR CUM IN MY WOMB!” Twilight begged.

“You’ll get it! You’ll get it! I’M CUMMING~!”

Luster hilted herself inside Twilight as her flared head broke through the cervix and entered Twilight’s womb, blasting a thick load of cum that filled the older mare. Twilight’s eyes rolled into the back of her head as she released a deluge of her mare cum all over her daughter’s crotch and onto the sheets. Luster kept humping her mother as her orgasm continued, filling the mare’s womb up to the brink as a slight bulge began to form on Twilight’s stomach. Finally, after a long and blissful minute, Luster’s orgasm ended. She pulled her dick out of Twilight’s pussy with a wet popping sound, letting thick gobs of cum pour out of her fuck hole.

Luster fell onto her rear as she watched Princess Twilight’s body slump onto the bed, legs still spread, watching as her seed slowly poured out of the Princess’ pussy. “Princess…that…that was amazing! Princess?” When Luster did not get a response, she slowly crawled around to Twilight’s head and noticed that the older mare was unconscious. “Wow, was I really that good that you passed out?”

The young mare felt a sense of pride from this revelation, fucking the Princess so hard that she passed out from the bliss of it all. Luster used her magic to turn Twilight over onto her back, and it was here that she saw the bulge on her stomach.

“Oh my, didn’t know I came that hard.” Luster ran her hand over Twilight’s distended belly, feeling yet another wave of nostalgia come over. “Huh, there’s that familiar feeling again…what’s that all about?” Luster shook her head, deciding to not linger on it too much. “Well, since you’re out, and considering you are my slut, I don’t think you’d mind if I helped myself, again.”

Luster’s cock was back to full mast again at the idea, using her magic to part Twilight’s legs a bit more, she aligned herself with her mentor’s still gaping snatch and plunged herself back in. She was still hot inside, and the added warmth of her own cum just made the experience even better. Luster decided she was going to fuck Twilight as much as possible, whether awake or unconscious, she was going to treat Twilight the way she knew wanted. The pink unicorn mare resumed her thrusting, slowly at first to enjoy the feeling a big longer. She began to rub the mare’s breasts and took one into her mouth, suckling it. And again, the nostalgia feeling came back.

This time she decided to let it wash over her as she fucked Twilight’s pussy, somehow it made this feel more loving and personal. Luster felt her mentor’s cunt tighten up, despite being unconscious, her body reacted just the same. Luster increased the pace of her thrusting as wet slapping sounds echoed in the room, along with the sloppy slurping sounds of her nursing from Twilight.

Speaking of Twilight, she was slowly coming to, feeling a heaviness in her stomach, and something thrusting into her. When she opened her eyes, she nearly screamed at seeing Luster fucking her again, and now nursing from her breasts. Twilight was a little clearer minded after having her heat satiated, the wrongness of this whole thing, of what they just did, there was no way to come back from this. However, in spite of this, Twilight could not help but feel happy.

She missed out on nursing her foal, it was necessary so that Twilight’s emotional attachment would not be as strong, and so Luster Dawn would not associate Twilight as being her mother. Still, that was a moment she missed out on, the proper bonding between mother and daughter. Now, it seemed, they were bonding in another way. It was wrong, she knew it was wrong, but…

Twilight wrapped her arms around Luster, making the young mare atop her pause for a moment, but only for a moment before she resumed her work.

Luster released her mentor’s tit from her mouth as she looked up and said, “You’re awake.”

“I am,” said Twilight.

“Hope you don’t mind, but I’m just about to cum again.”

Twilight wrapped her legs around Luster’s waist. “Go on, cum inside me again, as much as you want!”

“Thank you, mommy.”

Twilight tensed up as she felt Luster blow another huge load into her womb, and as ashamed as he was to admit it, she cummed as well. Another minute passed and Twilight’s belly swelled again. “Do you like cumming inside me…?”

“So much, I love fucking you, Princess,” Luster confessed, still humping away at her.

“Then, tonight, I’ll accept all your lust, and your love.”

The two mares went at it for the rest of the night, with Twilight letting her daughter have her way with her. Fucking her in her tailhole, mouth, and pussy repeatedly, swallowing and being pumped full of her child’s baby batter until the two of them were finally exhausted and collapsed into each other’s embrace.

{YOU DID WHAT?!} Sunset yelled.

“I’m sorry! I couldn’t control myself!” Twilight pleaded.

In the years since Sunset’s last visit, Twilight had developed a more sophisticated way of communicating with Earth. By using the journal, Twilight was able to create a machine that acted like a computer, allowing Sunset and Twilight to communicate in real time, and see each other’s faces. No more having to remake a single journal, now they could talk at any time they wanted without worrying about using up the pages. Twilight managed to create a smaller version so that Sunset could take it with her wherever she went. Which was how and why she was currently looking at her marefriend’s pissed off visage.

{I don’t believe this…twenty years! Twilight! Twenty years of not messing up! And then you just fuck our daughter?!}

“Okay, not to split hairs here, but she was the one who fucked me. I’m the one with an ass, vagina, and stomach full of her cum right now!” Twilight argued.

Sunset visibly shuddered at the visualization. {I don’t – I just – WHY?! Did you miss her that much that you decided that sex was the only way to bond with her?! Look, I know I haven’t been around as much I’ve wanted to, and that I haven’t been able to tend to your needs, but, c’mon, Twi!}

“I’m sorry! I don’t know how many times I can say it! Sunset! I’m sorry! I was in heat! And she acted so much like you that my mind was disconnecting between the fact that Luster is our daughter, during that time, in that state of mind, I only saw her as a mare!” Twilight lowered her head in shame as she closed her eyes. “No, that’s a lie. Part of me was still aware that she is my daughter, and somehow it only made me want to have sex with her more…”

Sunset ran a hand through her hair as she sighed in frustration. {What’s done is done. We can’t take it back. You said you were in heat at the time, tell me she used the version of that spell that only shoots blanks?}

Twilight deadpanned. “Unfortunately, not. I don’t know if she knew I was heat or not, but she used the version that is very virile. I took a pregnancy test this morning and verified that she did impregnate me. Like mother like daughter.”

Sunset facepalmed herself. {Horny little…Shit, okay, it’s only been a few hours, you are going to take a morning after pill, right?}

“Of course! I did right before calling you! The last any of us need is for me to be carrying a foal conceived in incest!” Twilight argued.

{Sorry, I’m just…trying to deal with this. Maybe it’s time we tell Luster who we really are to her? If we don’t, she’s just going to keep pursuing you.}

“I know, I’ll need to talk to Starlight and Sunburst first and see how they want to deal with this…it’s going to be a shock to them for sure, but the sooner we get this out in the open, the sooner we can help Luster Dawn,” said Twilight.

Sunset nodded. {Alright, once you get the chance to square that with them. Call me so I can come over.}

Twilight raised an eyebrow. “Isn’t the new semester for CHS about to start soon? You’re the principal after all, I wouldn’t want to mess up your plans.”

Sunset bit her lip as she remembered that. {Damn, you’re right. Plus, the parent teacher conferences and events…Maybe give me a month to see where things stand on my end, and once I’m sure we’re good, I’ll schedule some time off and make my way there. I’ll call you beforehand so we can coordinate.}

Twilight nodded. “That sounds good, take care, Sunset. I…I love you. Sorry, it probably doesn’t mean much after everything I just told you…”

{No, it does. I love you, too, Twi. We’ll figure this out, together. I promise.}

With that, the screen went dark. Twilight removed the journal from the machine, making sure it would not turn back on.

“So, that’s my other mom, huh?”

Twilight turned around and looked upon Luster Dawn, she was still naked, and still sporting the stallionhood she conjured last night. While Twilight herself was wearing a robe to hide her nudity from Sunset.

“Yes, that was your other biological mother, Sunset Shimmer,” Twilight answered.

“Wow, and she’s really from Equestria? She doesn’t look like a pony,” said Luster.

“That’s mostly due to her being in that world, sweetie. She is originally a unicorn mare, but when you cross over into that world, it changes your body to match the inhabitants.” Twilight walked back to the bed and removed her robe before sitting on the edge. “I’m surprised you’re taking this so well.”

Luster rubbed the back of her head as she said, “In all honesty, I figured something was up when we were…doing it. The feelings I was getting from you, the familiarity of it all, it was just too strong to not be something else. Sorry for almost getting you pregnant.”

“I took the pill, so you don’t have to worry. You’re lucky I keep a box of those in my nightstand just in case.”

“So, what happens now? I don’t think I can call you mom…but I also know that we can’t be lovers either…” Luster lamented.

Twilight glanced at her daughter and said, “Can’t we?”

Luster looked back at her bio-mother with surprise.

“I missed the chance to be your mother, no, that was my choice. We decided this so you could grow up normally and have a good life. Away from the political crap of my being a Princess, and stigma of being Sunset’s daughter,” said Twilight. “I hate to admit it, my instincts as a mother are strong for you, but I also see you as a beautiful young mare.”

“Then…?”

Twilight leaned forward and capture Luster’s lips. The two shared a long passionate kiss for a moment before Twilight broke it and said, “We’ll figure this out, just like Sunset said. But that’ll be later, until then…”

The alicorn mare crawled onto the bed and past Luster as she lied down at the head of bed. Once there, Twilight spread her legs and used her hands to spread her pussy lips.

“I’m still in heat, would you mind helping mommy quell it?”

Luster’s stallionhood sprang to life. “You want me to have sex with you, again?”

“No, I want you to breed me.”
