Mating Under the Moonlight
If you were to ask Blueblood of his opinion about parties, you would be quite surprised of his response. Ever since he was a colt, he always dreaded being forced to go to special events that were designed like parties, especially birthday parties. While he's always treasured his title of prince, this was the least tolerable part of being considered royalty. Call him unappreciative all you'd like, but as the years came and gone, he developed a loathing of parties in general.
As far back as he could remember, he wasn't able to produce a single memory of a time when he had actual fun at his own birthday party. When you're royalty, you have expectations on how you should dress, how you should eat, and especially how you should behave. Looking back, every birthday party he had, was treated more as a formal event, than a time to celebrate a young colt's special day. Over the years, as more and more birthdays came and went without a second notice, he slowly developed a desire to not even bother with celebrating special events at all. Though, not much he can do about that, when he's expected to attend what he dreads the most: holiday events.
This brings us to where he was now, stuck in Canterlot Castle, drinking his boredom away in cider provided graciously by the Apple family, stationed at some town called Ponyville. All the while, festivities sprouted around him, everypony none the wiser to Blueblood's reluctance to be here. Apparently, this was an important, and momentous occasion that should be held with as much importance as something like the Grand Galloping Gala several months ago: the Hearth's Warming celebration event. For Blueblood however, he couldn't give less of a damn if he tried. He would just continue drinking if anyone dared drag him into doing any tedious act he deemed unnecessary.
Drinking however, was Blueblood's biggest weakness, aside from his attitude. Whenever he even touched his lips on cider, his mind would drown itself in it's most protected secrets and desires, regardless of how unfitting they would be regarded by anypony else. Any and every last lewd thought he had, even those he had sparingly thought up of while sleeping, raised in more ways than one, once his body came into contact with cider. The more he drank, the stronger the thoughts and urges were for the poor prince. Needless to say, him currently drowning himself in cider was making multiple things of his rise.
Keeping all of this in mind, as well as the fact that he couldn't handle his cider well, and you ended up with one drunk, horny stallion, uncaring of anything happening around him, while his deepest, darkest desires swam with the oncoming cider sliding down his esophagus.
As much as he hated himself for admitting, he was still a virgin, though it was expected, as a prince was intended on being pure until their wedding night. He couldn't take advantage of his position of royalty to exploit a few random servants to attend to his needs, regardless of how much he desired so, so all he could do now was entertain his thoughts while having a semi-hard on.
Only ten minutes in, and having downed five mugs of cider, led him to think about his more recent dreams he's had during his more drunken-fueled rests as a means of preparing himself for this party. The freshest of these dreams involved him and his aunt Luna, rutting in her royal chambers. However, this dream wasn't anything new, as he kept coming back to this specific dream like a record being played on repeat for the past week, if memories served him right.
Oddly enough though, he didn't feel sickened by the idea of losing his virginity to Aunt Luna after the first night he dreamt of it. Not like it would ever happen though, for a multitude of reasons, the strongest of which being that they were both royalty.
Incest itself wasn't considered illegal, but the potential scandals that would happen if it were found it usually kept the vast majority of ponies at bay from entertaining the idea. Though, he had heard rumors of the newest princess, Twilight Sprinkle, or something like that, having sexual relations with her own brother, who happened to already be married to the Princess of Love, Cadence. Maybe she's into her husband tapping his sister, love does have more than one implication to what can be considered "love". Tartarus, for all he knew, maybe the same could be said about himself, and his apparent crush on Luna.
"Ugh, why did I have to be born into royalty," Blueblood quietly asked himself in a drunken manner. He liked the attention and entitlement of the position, but the expectations and responsibilities of the title were too much for him at times. If given the opportunity, he would change lives with one of the commonwealth ponies in a heartbeat. Unfortunately, life had given him this hand, so now he had to deal with it. And if his current predicament wasn't bad enough, both of his aunts had shown up in attendance for this big event.
'Yeah right, like I actually asked to be here,' he thought to himself.
There was only one thing that was keeping him from just ditching the party altogether, besides his duties as prince to be formal and attend the actual event to honor those who bothered to show up. That in question, was wanting to figure out why Luna has been occasionally glancing at his direction with an expression that had him confused to no end. He couldn't tell what she was thinking, but from the look of her predatory grin, he wasn't certain he wanted to find out.
"She's been giving me that same fucking look for the past hour! What the hell is she grinning about? Do I have cider on my attire," the stallion mumbled to himself, unsure as to why his aunt was giving him a feeling of a mouse trapped in a corner, facing a very hungry cat. Glancing back down at himself to make sure it wasn't his assumption, and miraculously not finding any during his feasting of cider, he stared straight back at the royal sisters on their thrones, surveilling the event with a welcoming aura.
Before he could make a scene demanding answers however, Luna started whispering to her sister on her left, before lifting herself off her throne, and began heading to what Blueblood could only assume to be her bedroom. Being drunk, horny, and angry was a very dangerous combination for any stallion to endure. Unfortunately for him, he could no longer control his body any longer, and began staggering his way out of the main throne room, following the general direction Luna seemed to head off to. 'I must ask her what her deal was. Why was she giving me that expression for what felt like forever? Did I say something earlier that she overheard? Was she trying to test him on how dedicated he was at being a prince?' Regardless of what the motivation may have been, the prince stumbled his way onward out of the main hall.
Every step his hooves made on his journey to confronting his aunt, made him question himself even harder with each passing second. 'What the fuck am I doing? Why am I heading towards her personal chambers? Is she behind this? If she isn't, how do I know I'm not just going to make an embarrassment of myself? Do I really want to do this,' the drunk prince thought to himself, juggling between his mind questioning his current actions and his body using his genitals as a sonar to finding his aunt's rump.
'To hell with this. I need answers, and I'm not asking Aunt Celestia what her problem is. I-If I want my answers, I need to ask her directly,' Blueblood reassured himself. Thankfully, since the location of Luna's chambers was directly past one of the castle's many bathrooms, any ongoers who questioned where Blueblood was going, didn't need much of a response from the drunk prince to guess where he was headed.
After several minutes of struggling to pilot his legs forward and not have his first kiss be the floor, he finally managed to reach the door to Luna's personal chambers. But right before he gathered the cider-fueled courage to question his aunt, he felt a massive sense of doubt and deja vu about this scenario. Here he was, about to question his aunt, drunk and with a semi-hard on, as if he were a wasted fool who just exited a bar! But blame it on his body for not particularity caring at that moment how he portrayed himself, he wanted some answers, no matter what happened to him afterwards. Someone should've really monitored Blueblood's cider intake…
What was intentionally a polite knock quickly dissolved into multiple harsh poundings on the expertly-crafted oak door. Too drunk and upset to care whose eye he caught, and not realizing how impolite he was behaving, it wouldn't be until the eighth rough knock when he suddenly collided with the floor, having slipped during the action of preparing to continue roughing up the innocent door.
"What a surprise, dear nephew! We weren't expecting any personal company for the rest of this glorious night," the Ruler of Night responded, after recovering from the shock of her usually pristine nephew bellyflopping onto her tiled floor.
Stumbling to peel himself off the ground, Blueblood produced as hard a glare as he could while intoxicated. Now was the time for some interrogation, not dozing off on his aunt's floor.
Doing his best to fix himself into something akin to proper, he questioned her, "Aunt Luna, I must have you tell me why you were prowling at me for nearly an hour while I was minding my own business. I-I-I demand reasoning behind you doing so," Blueblood slurred out, attempting to produce a solid statement past the sea of cider his mind was swimming through at this moment.
Luna's face morphed from pleasant surprise to a gentle smile. She knew what he was referring to. Glad to see he came to her first before she had to take more… drastic actions. "Calm thyself, nephew. Remove the grumpiness off thy brows, and I shall state my reasoning," she offered, wishing Blueblood would settle down as best as he could whilst he was very clearly wasted.
Following her offer, he slowly replaced his furrowed brows with one of annoyance from a lack of patience instead of pure anger. This had better be important, or there would be Tartarus to pay.
Now that he was a bit easier to converse with, her pleasant smile quickly shifted into a teasing grin, accompanied by what Blueblood could only guess was "bedroom eyes".
"We have seen your lurid, lustful dreams, nephew. We know you dream of us. Fornicating with us. Breeding with us. Why must you tease us so?" Luna asked, discreetly using her magic to close the door behind him, followed up by a quick turn of the lock, signifying to him that no one was entering or exiting without mutual consent.
Blueblood had never felt such a quick change from anger to sheer embarrassment before in his entire life. Feeling nearly any buzz he previously had vanish into thin air, his now mostly-clear mind stopped at any and all thoughts outside of what he just heard. Never had he considered the possibility that his aunt Luna, the one pony who could travel into anypony's dreams, had used her magic on him! That would explain why she kept glancing at hi- wait… hold on. Teasing? Did he hear that right? Was there a chance that she… wanted to commit incest with him? Any and all rationality left his mouth following what he asked next.
"Aunt Luna… what do you mean by teasing you," Blueblood cautiously asked, primarily so he wasn't misinterpreting what she was trying to tell him.
Luna's grin changed into a Cheshire cat grin, her eyes fixated between his cautious face, and what was hiding underneath his formal attire. "We believe you know exactly what we're talking about, dear nephew. We know what it is you've dreamed about most. Imagine mine surprise how… naughty, thy dreams were about us," stressing the word 'naughty' in particular. "If thy so desire, would thy like to become a stallion at long last," she questioned him, knowing well what her nephew's response was going to be, shifting her position on her bed to something a bit more alluring to the shell shocked prince.
If this were a dream, he hoped he never woke up. He had thought that dreams were a waste of time, that your destiny was made out for you before you could even produce a dream. Who would have guessed that it could decide history too?
Nervously activating his magic, Blueblood neatly, yet swiftly, removed every fabric upon his heated body, wanting nothing more than to shed himself of his outfit and remove any sort of barrier between his phallus and his destination.
Upon noticing the hesitation and eagerness in her nephew's behavior in cooperating with their mutual desires, only provided more fuel to the raging lust behind Luna's tone and posture. She rewarded him with a motherly smile while he dispersed himself of his tuxedo and undergarments, awaiting what was to become of them both in the next few minutes. Good thing she let her sister, Celestia, know beforehand of her plans for her nephew, and to have nopony disturb them for the next few hours. This was something she didn't want anypony interfering with, even if Canterlot was being invaded again.
Finally unleashing the beast from its prison, Blueblood sighed immediately after finishing up his duty of discarding his formal clothing. At 11 inches in length, and a meaty 4 inch circumference, the stallion's treasured dick was a sight to behold. Adding the appeal to it was the two apple-sized testicles escorting behind his member.
Having discarded her own attire long ago, Luna was amazing to see up close. With an ample bottom painted with her signature cutie mark, deliciously thick thighs, and supple, large teets above her soaked pussy, Blueblood couldn't ask for a more perfect partner to mate with.
With a now clear mindset, and his horniness leading the way, he quickly dashed over to where Luna resided, hunching over her with her back against her cotton sheets. Aiming his pride against her pussy, he was suddenly stopped by Luna's magic encasing him from any possible movement. Looking back at her in slight fear and anxiety, he was quickly writing his will as the seconds ticked on.
"Just one second, dear nephew. We are just as eager as you are, if the state of us is to judge. Before thy starts, would you perhaps like to partake in a few enhancement spells Princess Twilight Sparkle taught us? We're perfectly satisfied with what you have to offer us, but we figured thy may enjoy a little 'boost' to enhance the experience," Luna offered, signaling to Blueblood that she was telling the honest truth about his size.
A little confused about what she means by enhancement, the prince responded to her offer, "...U-Um, s-s-sure." Damn his virgin body language. But he trusted that Aunt Luna knew what she was doing. And if she was serious about it enhancing the feeling, he was all for it.
With a lustful glint in her eyes, and an excited smile adoring her beautiful face, she quickly casted two unknown spells upon herself, aiming them around her lower stomach region. Once she finished, she proceeded by warming up her horn for a series of spells to cast upon her mating partner. "Let's just say, thy will be experiencing pleasure beyond the stars themselves once we're finished," she warned him in advance for what would be nothing short of paradise.
Before Blueblood could respond, she fired the spells directly at his genital region, feeling at first a tingling sensation cocooning around his dick and family jewels. Slightly unsure of what he was going to expect, he tried asking his aunt, "W-what did you cast onto m-," cutting himself off when the tingling exploded into a wave of what could only be explained as pleasure and pure growth.
From Luna's perspective, her nephew's 11-inch phallus slowly expanded outwards from him, growing both in length and girth, until it finally stopped at what seemed to be about double his previous length and girth, ending with a dick measuring at 21 inches, with a 7-inch circumference. Once they finished their growth, a very strong scent rapidly started flooding the room, full of pure fertile stallion musk.
Soon following the halting of any additional growth of his dick, came part two: his testicles. Just like Blueblood's phallus, they slowly started bloating with fertile cum, eventually becoming large enough to where he would have struggle to comfortably lie down on a chair. By the time the expansion of his balls finished their own growth process, his balls were no longer simply slightly-above average sized. Each testicle now must have been watermelon-sized, loudly gurgling with cum production.
Blueblood couldn't speak aside from a long series of groans as the growth spells did their magic on his genitals, bloating them beyond what he thought would be even possible for a stallion to wield. He would definitely need to take a visit to that princess his aunt mentioned afterwards, and give his personal thanks for creating these spells.
Giving himself a minute to calm himself down from the pleasure those growth spells gave him, he stared at what he could only describe as a monolith of pure stallion meat. Shocked beyond comprehension, it was his aunt's voice that shook him from further processing of his situation.
Luna, now beyond aroused by the end results of the spells, simply stared at Blueblood's eyes in pure lust and adoration, bringing his attention to her own after allowing him a minute to recover. "Please call us Auntie, nephe- I mean, Blueblood~. And be sure to not pull out, we intend on being given foals from this, after all," Luna simply said, ready for what was going to be an incredible breeding session.
The prince was more than just cautious. "A-Are you sure you're prepared for this, Auntie?" He asked, worried about hurting her from this weapon he wielded between his legs.
"Yes, Blueblood. We casted a fertility spell and stretchiness spell, so our body can handle every inch and load of that glorious beast. Now ram it into us, and don't stop until we've been fattened up with your offspring!" Luna cried, setting herself up into a mating press position beneath him, desperate to be knocked up as soon as possible, more than ready to become a mother with her nephew as the father of her undoubtedly many foals.
As soon as Luna spoke that last word, all rationality left the prince's mind, and struck the gigantic cock straight into his aunt's pussy, immediately overwhelmed by how slick the walls within were. The further he shoved it in, the more of an outline of his new cock he was able to make out beneath her skin.
Every inch he inserted into her multiplied the pleasure Luna was experiencing, screaming in lust and joy at the gargantuan cock invading her most sacred of holes. She could feel every vein tightly rub inside her, while slowly succumbing to the stench of the musk flooding from his watermelon testicles.
About halfway in did Blueblood pause at feeling a barrier inside Luna's pussy. Was that her-
"Holy fuck, am I at your womb, Auntie?!" Blueblood proclaimed, shocked that he could feel his now bell-shaped head smacking against the entrance to her womb.
Hearing Blueblood state that he was already hitting her womb with half of his cock still outside of her, broke the dam she had kept from unleashing. "AHHHHH!" she howled, a massive orgasm squirting all over her once clean sheets.
Taking a second to recover from one of the most intense orgasms she'd ever experienced, she responded, "Y-yes, you are. Now listen to us, Blueblood, dear. We want you… to ram thy cock into our womb! Breach our most treasured place, and claim our womb as yours and yours alone," she passionately instructed to him, wanting nothing more than to have him mate her with everything he had.
That was all Blueblood needed to hear, as he slowly shifted his hips to where he took out half of his cock out of Auntie's pussy, before gathering all the energy he had in himself, and forcing his entire cock inside, piercing past the barrier to her womb, and stuffing her to the brim with the entirety of his cock, followed up by his now watermelon testicles loudly slapping her ample ass cheeks.
Luna's expression was that of absolute paradise and pleasure, climaxing once more following her statement, "Holy fu- it’s sho biiiig~! Uuuuuhhn, I’m cumming again!” Her eyes rolled back in ecstasy as she orgasmed, the hammering of her nephew's bell-sized cock-helmet upon her womb forcing her to juice and clamp down on him. Tangy, musky love-nectar made a mess all over his pelvis, dripping down his massive nuts. All the while, both of them took notice of the gigantic bulge now prominent on her belly, imprinting the veins and head of Blueblood's cock as he demolished his way into the back of her womb, and then some.
Taking a few seconds for both of them to recover from what they just managed to accomplish, Blueblood stared directly at his Auntie's eyes, giving a smirk followed by passionate adoration in his eyes, and gave his Auntie a firm slap on her plump ass. "Tell me what you want, Auntie. Tell me that you want my foals" While pulling out one-third of his titanic dick, in preparation of what was to come.
Fully enveloped in passionate lust, and wanting to express her honest feelings for her lovable Blueblood, "We want your foals! We want you to bloat us up with your smelly cum, and keep doing it until there's no possible way for us to not be knocked up," wailed the alicorn, needing her mate's cum in her as soon as possible!
Tightening his grip with a quick burst of magic, the prince rammed his way back into his cock's new home: the deepest parts of Luna's womb. Blueblood quickened his pace, pounding at her innermost chamber like his life depended on it, desiring nothing more than to rut and breed his incredibly attractive aunt until the sun rose from the horizon.
His hips thrusted faster and faster, assisted by a quick use of magic on his waist to reduce the cooldown between thrusts, until they became a blur. His massive cock disappeared and reappeared like an illusion within Luna's pussy, his watermelon balls slapping her anus with each thrust. The gargantuan pillar of stallion meat jackhammered in and out of her sacred hole, reshaping her passage to properly pleasure her beast of a nephew. His constant thrusts forced the majority of the air she had out of her poor lungs, leaving her only able to gasp, pant and grunt as she was rutted like an untamed animal, neck bent back in absolute pleasure, screaming to the moon she controlled with every orgasm she felt.
As the blonde bull of a stallion forced his way into owning his aunt's womb, he started a series of vicious slaps to her rump, leaving a red imprint where he demonstrated his ownership of her. Every few thrusts was met with their own slap to her ample bottom, resulting in a wave of cum to pour out of her from the encumbering pleasure she was experiencing.
"What a naughty aunt, tempting her only nephew into breeding her! I bet you wanted all of this to happen, didn't you?" The walls of her womb clamped down on him, informing him that he was right in his guess, making him growl obsessively. "Then I better give you what you want, Auntie! Take my entire load of jizz, and fucking get pregnant!" He shouted, shoving his titanic shaft as far in as he could, causing a huge indicator of how massive he currently was to protrude out from her stomach, in preparation for the finale.
Luna howled with primal delight at Blueblood's claims. "YES, YES! DO IT BLUEBLOOD, GET US PREGNANT! STUFF US FULL OF YOUR MUSKY CUM! OUR BODY EXISTS FOR YOU TO IMPREGNATE! USE US HOW WE WERE MEANT TO BE USED, NEPHEW!”
“YOU’RE SUCH A SLUT, AUNTIE! I MAY EVEN TAKE YOUR HOOF IN MARRIAGE!"
"WE LOVE YOU TOO MUCH TO EVER BE WITHOUT YOU AGAIN!”
“YOU’RE THE BEST, AUNTIE! NOW GET PREGNANT!”
“KNOCK YOUR AUNTIE UP!”
“AAAAHHHHHH!!!”
Both relatives moaned in harmony as Blueblood began his fertile release. Easily the fattest load he had ever unleashed, a massive tidal wave of hot spunk blasted into her womb, instantly filling her to the brim with swirling, sloshing, smelly cock sludge. And it just kept coming, the gigantic slab of pure stallion muscle pulsing and vomiting bucket loads of cum every ten seconds. Luna, having already developed a slight bulge in her stomach from the excessive precum Blueblood had produced in her, swelled much further outwards as her nephew pumped her womb full of his smelly cum. The loud churning and groaning sounds of Blueblood's testicles as they continued mass production of cum could be heard clear as day, and only fueled the lust and passion in their climax.
Her womb bloated out so much, that Blueblood had to lift her off the ground with his magic, shifting himself into a more comfortable position as he continued the torrent of cum into his Auntie's extremely fertile womb. Eventually, her stomach had become bloated to the point where it could touch the ground, as if she had swallowed an entire manticore whole, stretching outwards like a balloon. The princess could only endure the never-ending series of orgasms for so long, while having her rump slapped into a bright shade of red as her darling nephew gave her no less than a dozen foals, before she collapsed from the pleasure.
'I should definitely give Twilight a personal thank you for developing these spells," Princess Luna hought to herself as she finally accepted the darkness of unconsciousness.
After around fifteen minutes of constant orgasms from both sides, the flooding of both Luna's womb and the room around them finally settled down. Both ponies were happily unconscious, ankle deep in steamy, musky cum, with only the airtight design of Luna's reinforced oak door preventing any of their evidence from escaping.
Epilogue
Luna was currently resting on a specially-made chair within her personal chambers, professionally created by one of the royal staff skilled in woodworking. Monitoring the moon she had become very close acquaintances with for the last millennium, she cradled a heavily swollen stomach despite only being a month pregnant, she softly smiled to herself, knowing that she found a keeper of a mate.
"Time to check up on my darling's dreams once again", she whispered, smiling to herself, looking forward to holding the results of their love once their many foals finally arrived.
