Secrets of the great, magical alicorns

Things better left uncovered

Written, translated and edited by me: DarkShadowSpark

Much had become known about alicorns over the last 30 years. Especially Princess Twilight, but also Cadance, Luna and finally Celestia had worked hard and revealed a lot of things that had been hidden before about what they were.

It had therefore become generally known that an alicorn was truly immortal and not just possessed a very long lifeline. That each of them was incredibly powerful and could control celestial forces with laughing ease - even if that had been widely known before. That they possessed the ability to bypass everyday needs like eating, drinking, sleeping, etc. with the help of their alicorn magic and much more.

However, one thing wasn't clear until today. Why did the alicorns become increasingly stronger with age? In the beginning, it was easy to assume that they were still maturing and therefore their powers were increasing, but at some point, this fact could also be disproved. After all, Luna and Celestia were over a millennium old - surely, they couldn't be still maturing?

Whenever the princesses were asked, they would say that they were just exercising to further improve their abilities, and most pony’s simply believed that. However, an alicorn's abilities seemed to increase only every year at the same time, which was illogical. Thus, a few were skeptical, such as Flash Sentry, who was on his way to the Castle of Friendship, at the command of Princess Twilight Sparkle herself. Something about the growth of an alicorn wasn't right, and he would eventually find out what it was. Although, of course, he wouldn't directly approach the princesses about it. Even as a longtime palace guard, he didn't dare address the royal alicorns on something like that directly.

He was now standing in front of the palaces doors and with a last deep breath, he lifted his hoof and knocked hard three times against the massive entrance door of the building. He didn't have to wait long, because just a few seconds later, the door was enveloped in raspberry-colored magic and began to open on both sides inwards.

Inside the doorway, he could see Princess Twilight Sparkle herself standing in all her pristine, radiant, flowing glory. Over the past three decades, the youngest of the princesses had also grown considerably and was now on par with her former mentor.

She also looked almost exactly the same. At least physical the alicorn had the same slender build, long legs, flowing mane and tail, and a very long horn, like it was common for a grown alicorn. The warm smile he was used to from the mare, however, had not changed in any way and was still just as friendly and welcoming as it had been so many years ago.

"Flash! It's so nice to finally see you again. It really has been a long time since we've seen each other, hasn't it? How are you?"

As befitted for a guard in front of a princess, Flash bowed in a deep honoring bow.

"Your Highness, Princess Twilight Sparkle. What an honor to genuinely meet again. I happen to be very well, and likewise, I hope the same is true for Your Highness. However, may I ask why I was honored to be invited to your castle?"

Twilight smirked. " Rise, Lieutenant Flash. Also, please, Twilight is enough. I've had enough princess things to do today, I don't need to be addressed as a royal in my free time as well."

Rising, Flash's cheeks began to turn red in embarrassment.

"My deepest apologies Prin- Twilight. If that is what you wish, then I honor that."

"Thank you. Now come on in and follow me to my library. I didn't call you here for nothing, after all I have a special task for you," Twilight remarked as she turned away from the door and trotted deeper into her castle.

Surprised, Flash Sentry followed the large alicorn mare quickly.

"Oh, and do you mind if I ask what the task is?"

"That my dear, you will find out soon enough. It's best if I show you. Makes it easier to understand."

Twilight turned left around the next corner of a corridor random to Flash. Regardless of how the princess found her way around her own castle. To him, every door, hallway, and turn looked identical. So, he hurried, to not get left behind by the alicorn. Getting lost in her castle wouldn´t give a good impression on himself.

As he followed her around the corner, his face flushed once again deep red, for as Twilight turned the corner, her tail swung to the side, giving Flash a brief and good view of Twilight's most private backside.

Continuing to blush fiercely, he lowered his gaze deeper, concentrated on keeping his body under control. It wasn't proper to stare, certainly not at a princess, and he would be incredibly embarrassed if princess Twilight caught him doing so.

Just a stupid coincidence, he told himself in his mind. It was impossible that Twilight might want something from him. He was just a lousy Pegasus guard while she was an alicorn princess and previously one of the most respected ponies in all of Equestria.

Less than a minute later, they reached a large double door set in solid crystal and made of dark wood with gold ornate accents. They opened with Twilight's magic, the mare indicated with one hoof for him to please step inside.

Once he stepped through the door, Twilight followed him in as well, closing the door shut behind them.

The room itself was, as expected, one of the several large libraries the castle had. Even though this one was a lot smaller than he had expected with the well-read mare. Only three alicorn high bookshelves were lined up along the walls. Each one of them no more than 2 meters long at most. In a sudden flash of inspiration, Flash guessed that it was most likely Twilight's private library. Hence the relatively few books the alicorn had stashed here.

The alicorn in question while he had been looking around had trotted passed him and was now leaning back against one of the bookshelves, sitting across from him with her two rear legs splayed out to the sides. Both of her grand lavender wings neatly folded behind her back.

Even if he tried not to spy and instead tried to look higher, at best into Twilight's eyes. So, he still didn't miss the fact that the alicorn's sitting position once again gave him an extremely good view of the mare's private bits. Her two big, juicy teats with their darker nipples, her shapely rump featuring not too much or less volume for his taste and finally the alicorn's massive, engorged marehood wrapped in lavender fur moistly glistening directly below.

Shocked, he stared at Twilight's face with open muzzle and momentarily lost for words. Before he found his voice at last.

"Ah ah ah, no need to fret. It's all part of the process. Don't be shy, just take a good look at everything of me you wish, for the moment I'm not your princess, I'm a mare like any other," Twilight interrupted him as she winked at him and spread her rear legs a little wider. Which resulted in the two outer lips of her marehood being pulled slightly to the side as well, and he could now look directly into the alicorn's most private rich-pink depths.

At first, he resisted to really look down at her again. But when Flash saw Twilight's gigantic clit momentarily peek out of the top of her pussy at the edge of his field of vision, he couldn't hold on any longer and lowered his gaze back down to the alicorn´s sex.

"Ehhh- ok...if you say so, I'll take your word for it."

Upon which he raised his eyebrows and stepped closer to Twilight. Everything he saw was heavenly. Every last detail of Twilight's marehood and other sexual organs was as perfect as the alicorn mare herself was godlike. And he tried with all his might to keep himself under control as the royal mare continued to wink for him in a steady rhythm. The alicorn seemed to have worked a spell on herself so far that had concealed her lust and arousal. But now it seemed no longer present and the inside of Twilight's vagina was intensely wet and he could see a few drops of her mare honey beginning to flow onto the floor without further stimulation. As he took another careful step closer, his nostrils flared as they caught the potent innermost scent of the princess that had meanwhile begun to drift up from the alicorn's crotch.

Twilight was definitely in heat.

"Like what you see?". At the sudden, joyful comment, Flash jerked his head back up and broke eye contact with Twilight's damp, dripping mare slit as his cheeks reddened fiercely. Simultaneously he took a far greater step back from the alicorn as his earlier ones had moved him towards the princess.

"Y-yes very much in fact”, Flash stammered. “Everything I see of you my dear princess is beyond flawless. Still, I'd be quite interested to know now what you called me here for. Surely not just to display yourself to me and seduce me with your flawless divine body. You are an extremely attractive mare, that I must confess, and I am also single, just like you, though I think you know that already. Yet I don't believe that you and I would be made for each other. I don´t believe I´m deserving for that gorgeous alicorn pussy…"

Twilight chuckled. "You're right, that's not why I called you here. There are other reasons for that. And please don´t make yourself seem so bad. But one thing at a time, for now I strongly assume that you wouldn't just like to look - Am I right? Go ahead, your free to do what you want - I'm all yours." Twilight extended her hoof and pointed down with it between her spread thighs and right at her slowly winking moist marehood nestled in her crotch.

With that, Flash had the last confirmation he needed to throw overboard all the barriers he previously had towards his princess and with suppressed joy, he took a few steps forward.

Flash could only lick his lips and edged closer, taking further in the incredible aroma of the royal mare's scent billowing up from between her hindquarters. He shifted his weight and leaned down a bit more, down toward Twilight´s deep lavender, twitching marehood. Just inches in front of her aroused lower folds he eased off though, unsure if he really should close the final distance to her drenched sex.

Flash looked up at Twilight from between her powerful, long legs. The alicorn mare itself remained leaning against the high bookcase, doing nothing more than watch, waiting for him. So, he looked back down at Twilight's lavender pussy. Her fuzzy violet tail underneath, with its pink streak running through it, was like a way sign, leading him to his tasty wet destination. Twilight probably could feel his warm breath on her nethers, at least her body practically quivered with anticipation and her marehood leaked some of her wetness as he once more looked up into her deep, sharp and caring eyes.

That single brief look of infinite kindness from the alicorn gave him the last confidence boost he needed and Flash stuck out his tongue and moved his head down into Twilight´s lap, finally making contact with her moist bulging pussy.

Twilight gasped, feeling his warm tongue on her burning lower folds at last. Yes, she had felt the sensation of a cunnilingus many times before, her friends and her had always been eager to help each other’s out in times of greatest need, but it was still always very intense.

Flash made a few experimental licks into the entrance of the alicorn´s sex, testing the sweet flavor of Twilight's grand marehood. His eyes going wide as the exquisite taste of the royal mare´s sex graced his tongue, gradually increasing his motions he licking longer, and harder all across the alicorn's engorged, wet pussy.

The pegasus guard hadn't had a lot of experience with sexual activity – or other mares for that matter – but he was familiar with what was generally always pretty much the same taste in a mare; it always differed a bit, but still a pussy´s taste remained on about the same level.

Princess Twilight's unique flavor, however, was something completely different – the taste of her marehood much more potent, fresher and more fertile than anything he'd ever tasted up to that point. It made sense, too. If one was blessed with eternal youth and health like a godly alicorn was it rendered ones scent and taste litteraly divine. A simple but true fact that kept one's body always in perfect physical condition and on the very verge of sexuality that a mare may ever possess.

Unable to withstand, he surrendered himself fully to the mesmerizing flavor of Twilight´s mare juices and her heady alicorn scent.

Panting, Twilight threw her head back as she watched the stallion's head quickly boob up and down between her spread thighs, licking her moist folds. Some seconds afterwards Flash leaned his head lower, licking into the widening entrance at the top of her bulging pussy, pushing his nose further up into her wet female slit as his tongue gradually worked its way down her sex. Slowly spreading her marehood to both sides of his snout as Flash licked, sucked and dove deeper into her.

Twilight's marehood was heated, but not uncomfortably so and he could feel the strong motions of both engorged lower lips trying to pull more of his muzzle into Twilight´s folds. Wetting the fur of his snout all around his face and drenching him in her pure alicorn scent.

While he would have liked to keep pushing until he brought Twilight to orgasm, for one thing he was pretty sure that an alicorn's stamina was a lot higher than his own and on the other hoof, even though Twilight was so amenable to him, he still didn't think it was appropriate to push the princess to and over the brink.

His mind made, he regrettably pulled his muzzle back out from the alicorn´s pussy with some difficulty due to the alicorn´s inner marehood muscles forcefully clenching around his snout as he pulled away, which made the lower lips fall back to their usual closed position with a soft squelching sound after he had removed his jaws. Raising his head and licking the last drops of Twilight's scented mare honey from his muzzle with his tongue, Flash couldn't help but moan once more in pleasure from the divine taste.

He received a mischievous and mirthful sounding silent chuckle from the tall alicorn for that.

Using one of her front hooves, the alicorn mare pointed to the ground directly in front of her. "When you've had your fill of tasty alicorn me, come over here and settle down with your back in my lap. That way I'll be more than happy to show you what I really brought you here for my dear Flash."

Flash lingered for a few more seconds where he was standing, his gaze completely focused right between the alicorn´s rear legs and onto Twilight's divine, winking marehood beautifully and grand nestled within with all of its deep purple and rich inner pink. Some visible moisture of the alicorn´s sweet scented arousal spread right before her pussy onto the floor while even more of her honey oozed and dripped down from her plumb lower lips. Oh, how he would love to bury his own 'tool' as deep as he could in there and rut the mare until even an alicorn's stamina failed. But it would never come to that, he knew...Or at least he didn’t want to try his luck for now with a real princess. That probably was a much better answer.

Accordingly, Flash nervously raised himself, took some hasty steps back from Twilight just moments before he grabbed his confidence and stepped forward once more to the lavender alicorn. As he had almost reached the royal mare, he flipped his back to the alicorn as he dropped to the wooden floor just in front of her and in between her still parted ample haunches. He was about to ask another question, but made a startled exclamation as Princess Twilight pulled him right up against her soft and massive frame with a powerful swift tug of her front hooves and alicorn strength.

"I said IN my lap, not just in front of it," Twilight teased with her warm, mirthful voice and a little giggle.

Flash was at a loss for words. He was utterly helpless in the alicorn's mighty and tight grip. His heart skipped another beat when he felt Twilightˋs powerful alicorn magic slowly lift his bushy tail out of the way and once more as the alicorn trusted her pelvis vigorously forward against him, so that the back of his rear now touched the alicorn's very broad and slick marehood directly. He squirmed in place, clenching with his hooves at the wood floor in an involuntary moan. His cock springing to life between him and the ground, stiffening too attention with the unexpected hot heat of the alicorns very wet marehood now easily rubbing against one of his most pleasurable spots, limbs quivering.

He felt the alicorn's soft, warm lower lips press and massage firmly directly against his rump as Princess Twilight's engorged sex powerfully winked open. His mind reeling as his shaft throbbed needily before him in tune with Twilight´s pussy, a fuzzy haze taking over his mind and filling him with incredibly pleasure that replaced the rising fear. Twilight´s broad and equally as warm teats as her marehood where grinding just inches higher into his lower back and he could feel every single tiny part of her two soft mounds pressing against his fur as well.

His front hooves moved to his throbbing, stiff cock as he could perfectly feel the slow movement of the alicorn's massive clit pulsing out of her pussy and grinding against his butt, stroking himself and letting out a deep groan of pleasure as both lavender hoofs now gripped him tight against Twilight´s belly. A strong hoof on his neck, the other around his midriff, practically squeezing and rubbing him into her soft, plush and flawless lavender fur.

Flash whimpered lustily, his hooves working himself to the edge, shaft slickened with pre but unable to push himself over the edge. He didn´t know why, but it felt incredibly good to touch himself and stroke his cock in the alicorn's embrace and he just couldn´t stop. He felt his cock twitching warmly against his own belly, intense pressure almost painfully erect, the twitching seemed to translate into his stomach, jerking cock pressed tightly against his skin. But something was wrong. Very wrong! He knew it.

With a confused motion he tried to pry his body away from the larger mare, but to no avail, the distinction between his back and the belly of the alicorn seemed to have smoothen away with a deep shudder within seconds before. Through his haze he felt the twitching, moist warmth of the alicorn's grand marehood behind him heat up, the warmth of Twilight's pussy spreading out, diffusing within his entire rear and sending a sudden single strong throb up from his haunches into his entire chest.

“G-guh… W-what’s…” Flash tried to say almost breathless, his eyes rolling back from the extreme pleasure he suddenly felt.

“Shhh…It´s all okay”, the alicorn lovely whispered silently into his ear as she carefully and lovely stroked his belly with her soft hoof and tugged him closer to her belly with another kind but powerful hug. “Your joining me! You enjoy and love this beyond everything else my dear Flash, remember?! Forget all your worries you ever had for now I'm here to ease them. FOREVER!”

“Mnnph…” Flash deeply moaned, squinting his eyes shut for a moment to keep from being completely overwhelmed. He moved his forehooves in an attempt to re-explore what was happening with his back, but felt them compelled to hold tight up against his chest. A spreading tightness in his muscles keeping them in place as he felt his entire spine tense up with another bodily throb from behind him that seemed to bring him closer to princess Twilight. Something was clearly very wrong with the way how the beautiful alicorn mare treated him. Even if the cares he received from his princess by her soft hooves brushing over his coat felt far better than anything else he had ever experienced in all his life.

What! Was! HAPPENING!

The blazing heat continued to spread up through his body, and without him realizing, the flesh between the alicorn's moist crotch and his butt had merged fluidly into one. Twilight's powerful immortal heart was now pumping in replacement of his own, while the blood rushing into his head caused his vision and mind to swim and his entire body to tense further.

Another twitching throb filled his being with fright, as he was suddenly aware of the heartbeat of the alicorn mare taking over his own. He wanted to voice something, but a sudden gasp was all he could manage as all the air was expelled from his lungs with a breathy puff, his meager organs beginning to wither away inside as his anatomy was overpowered by the alicorns stronger one. Every bit of strength he had left was slowly extracted from his body as the seconds ticked on. And as he tried to move once more, he realized it was almost entirely impossible.

He felt his hips tighten as the control he still had over them slowly drained from his body. And when princess Twilight indicated for him to look down with a nod, his mind finally understood what was going on...his body slowly merged entirely with the alicorn's.

His legs, up to his hips, had nearly completely merged with the alicorn's and were staining the fur on the inside of both of Twilight's legs in his characteristic orange. Only towards the ends of his hooves did they still protrude visibly slightly out from the inside of Twilight's lavender legs. But while Flash was still staring down in disbelief at the fusion of his body with the alicorn mare's, he witnessed and felt his legs sink a little deeper into Princess Twilight's gorgeous frame. Her flesh feasted on his, drawing it into her to fuse and use his mass deep inside her for her superior and gorgeous alicorn form. Her lavender fur spread over him very slowly but steadily, replacing his bright orange as his body was absorbed.

The rest of his body, to had fared no better. His crotch had fused almost completely with Twilight's and his cock and testicles were now perfectly level with the alicorn's hips. As if they were no longer his own genitals, but those of the alicorn. And they probably now also were. Only the fur color was still his own and his two round, thick and brown testicles continued to twitch in staggering pleasure as was his mighty horse cock between princess Twilight´s widely parted female haunches, while leaking drops of his pre onto the ground.

He felt the skin and flesh in his crotch tighten and with a pleasured grunt ten seconds later he felt the skin right below his testicles suddenly give way and split wide open. Flash instantly knew that it could only be the alicorn's moist marehood reforming and nestling into his crotch as the same was claimed by Twlight. A familiar pleasured twitch confirmed his suspicions as the alicorn´s sex forcefully pushed out of him while it fattened with mass and blood under his throbbing cock and forced his testicles higher.

With great difficulty, he slowly managed to turn his head to the left side and subsequently realized that his body up to just below his neck wasn’t there anymore, it too had almost completely merged with Twilight – the alicorn mare was really making him a permanent part of her. Absorbing his body by fusion Flash into her frame, breaking down his body, flesh and bones into magic and pudge with her superior alicorn biology and making his frame entirely her's down to the last atom.

A sea of fear and surging lust flooded his mind, almost taking away all his racing thoughts. This was impossible! Such a thing could simply not happen, there was no explanation for how it could be possible for princess Twilight to accomplish what she did. Not even for such a mighty alicorn as the great lavender mare was. Surely other guards would be looking for him, his relatives would be missing him and trying to track him down to find out what had happened to the pegasus.

"Don't worry Flash. I have already briefed the other guards and your family that you had to go on a long and dangerous mission on behalf of us princesses. While they weren't bright-eyed and bushy-tailed, they understood that this is, after all, the job of a palace guard. They accepted the chance that they might never see your face again as you never return."

THAT! – did not help his panic in any way.

He tried to squirm in place but found his motions restricted. Most of his muscles had tightened or vanished as they were broken down and devoured, and about 70% of his body had been absorbed by the bigger alicorn by now. But through all his energy and relentless bucking motion he only succeeded in twitching weakly against the belly of the alicorn.

As the latter rubbed him up and down with one of her soft forelegs and right into her very body, Flash's mind was sent into a dangerous vortex of tantalizing pleasure. Yet at the edge of his perception he was still feeling his body slowly sink into Twilight´s flesh and wither away within the alicorn mare.

He could feel his body continue sinking deeper and deeper into Twilight's belly with every passing second as the princess claimed him and soon only the front part of his chest and both front legs were sticking out of the alicorn's chest. The rest had been absorbed entirely into the greater physiology of the princess. His head was also now directly under the smirking chin of the lavender alicorn and with each passing second, he lost ever more of his own body to the princess as he ultimately neared her for the very last time.

But even the things of him left outside the alicorn´s mighty body only lasted momentarily as Flash felt Twilight's magic begin to push his head unrelently closer to her long throat. He tried to fight back with all his might, but even with all his former strength, he would have never been able to even begin to fight the magic of an alicorn. Let alone that of the alicorn of magic.

He started to flick his ears in all directions in irritation, but quickly felt them touch Twilight's neck and melt into the alicorn's fur, whereupon he lost all sensation in his ears. He could also by now taste a strange but not unpleasant and somehow very familiar musky taste in his mouth that continued to rise the more of his flesh was absorbed into the alicorn. Yet what kind of it was he just couldn´t quite put his hoof down onto. Shortly thereafter, he also began to lose all remaining feeling in his forelegs, and as he struggled to look down, he observed them begin to shorten and pull into the alicorn's body at a gradual yet undeniable erasing pace. Under normal circumstances, this should have greatly worried him, but for reasons he couldn't quite explain, his lust only increased at the sight of him losing his body to the alicorn mare bit by bit, once again numbing his senses almost completely. His front legs continued to shrink and soon only the stumps of his hooves protruded from Twilight's chest, but even these were absorbed by princess Twilight's body a few seconds later fusing away completely under his – or by now rather her – plush fur.

Things got even worse for Flash seconds later, though, and another breathless gasp escaped his near-totally devoured lungs by Twilight's alicorn body in intense pleasure. Just above where his pounding brown horse cock now blended flawlessly into Princess Twilight's still orange discolored crotch above her damp, winking snatch, his flesh slowly began to bubble with powerful magic and swell as the fur on his lower abdomen began to pull back into his skin. Eyes wide, Flash watched what was happening to his body, even though he somehow already knew the end result of the transformation of his very flesh considering what so far had happened to him caused by the alicorn´s godly magic.

The flesh of his underbelly soon began to bulge out into two steadily growing mounds of flesh, rapidly developing into two large pads of fat and very characteristic equine mammary teats in a darker shade of purple. The exact same color and teats Flash had seen on the alicorn's vast frame just a few minutes ago and felt grinding against his rear before they fused away into him.

Princess Twilight's broad teats that had just grown considerably fast out of his underbelly – her literal milk-leaking secondary sex characteristics as an alicorn mare shoving themselves right out of his very flesh and body and nestling themselves into his frame – only hammered home the fact that his body hardly belonged to him anymore, but rather to his alicorn princess.

Shortly thereafter, the remaining elements that had still been his orange fur color on Twilight's body slowly turned to the alicorn's characteristic lavender, erasing the second to last indication that he had ever existed.

All that remained now was his head, but Flash knew that even that wouldn't last much longer. Whatever Princess Twilight did with him, his body was absolutely no match for an alicorn's physiology.

The back of his head began to merge with Twilight's neck and he felt his own thoughts slowing down, but before he could worry about it his head suddenly felt like it was going to explode as hundreds, if not thousands, of individual strands of thought flooded into his head second by second. This made him realize that these were most likely the princess's personal thoughts. Just how in the world could a single pony think of so many things at once without going completely insane, he asked himself with one of the last thoughts of his own that he could grasp as his head disappeared about halfway into Twilight.

As he once again drifted a bit deeper and his head was now only just barely outside of Twilight´s, with only about his eyes and snout sticking out of Twilight´s neck, his ability to think independently left him completely. With no strength left to fight against his assimilation into the clearly far more mighty alicorn he surrendered to the overwhelming vortex of the lavender alicorn´s mentality as his eyes fused shut and all of his remaining vision disappeared into an all-encompassing darkness with a last drop.

But that darkness lasted only for a few seconds and now that he was cast into heated, throbbing darkness, he experienced so much new pleasure and impressive strength swelled through his body. In a matter of seconds, he also could clearly feel both his own previous cock, that was now assimilated into Twilight's crotch at the very edge of being stiff and almost bursting with arousal grinding against her two great teats as well as Twilight's hot, moist marehood, swollen by her intense heat, as it winked in the same rhythm to his cock below against…him?

Flash was trapped with his thoughts stuck to the building heat and pressure inside him until he could stand it no longer. With a sudden, jerking throb, he felt the sticky semen explode in his member, shooting up and leaking in thick strands onto the wooden floor in front of and over the alicorn's still massaging front hooves. Out of the fat and jerking brown member that was once his own as the alicorn´s careful hooves rubbed up and down the length of the cock, rubbing his semen deeper into Twilight's fur.

He began to become aware of a strange new sense, a vague notion of the alicorn’s entire divine body. Her soft and careful hooves, the strong main body of the princess, her grant wings and fast mind as well as both the alicorn´s drenched, heated and plumb marehood and her new assimilated, throbbing stallion cock below. He could sense all their orientation, presence and need, but not see on his own. He felt his own new form foremost, but there was a sense of belonging to a greater whole here… he’d become a part of a creature larger than himself.

A small part of his own mind, however, seemed to have remained completely untouched and even though most of it was overtaken by Twilight's much stronger mind, he realized that he had now become his former cock in the truest sense of the word, with the small amount of his personal thought´s left to him embedded into the long, light brown appendage by some of the alicorn´s magic. While all his former senses had vanished, they were substituted by Twilight's much finer ones, kind of giving him the ability to see, taste and smell back, even if the alicorn was who now controlled all of him and he was only a small throbbing passenger in this divine whole. Twilight's nostrils flared widely eagerly as they took in the first breath of his enchanting vital stallion scent that emanated from him now and that musky scent also mixed with an intoxicating more potent and sweeter one of fertile alicorn mare steaming from within Twilight´s grand, moist marehood twitching below him.

Flash heard Twilight's voice as she bent her head down and gazed down at him – her new mighty alicorn cock – lodged between her haunches. Through Twilight's sharp eyes, he could see the many little specks of his white cum on the floor, across most areas of her otherwise pristine lavender fur and dripping down his jerking form, that had once been the useless parts of his former body melted down into alicorn spunk. Thus entirely worthless to the alicorn and expelled in a wave of deepest pleasure by Twilight´s supreme biology through him.

Just below his two thick balls, meanwhile, a growing pool of Twilight's sweet smelling mare honey had gathered and now began to leak further out under him – the cock. The honey itself had been dripping out of the alicorn's marehood for the past few minutes with each of her aroused winks.

Twilight – no they both, as he had been flawlessly merged into the alicorn´s body – Flash corrected himself, were definitely highly aroused. Flash could still clearly feel Twilight´s powerful marehoodˋs lips winking against the base of his testicles in a steady and strong rhythm from below, coating them in their intense wetness and unique, powerful scent.

"That's right, surrender to your fate. You're doing really well – better at least than your other two colleagues the last few days." Twilight's voice was kind and gentle as she continued to smile down at him or more precisely her new fat alicorn cock.

Hang on a second. What was that supposed to mean? But before the thought could even fully come to fruition in the connected mindset memories of days gone by forced into him and crossed his metaphorical eyes while the next lustful comment from princess Twilight confirmed his suspicions.

"Oh my god yes, Luna was so right, I should have taken a stallion much earlier instead of just mares, this feeling is just heavenly. Why didn't I think of that on my own earlier? Also having a mighty equine cock in addition to my mare pussy is soooooo much better. Kind of limitless possibilities!"

Twilight's voice was pure lust, her breathing was getting jerkier and faster and Flash knew exactly what that meant, not even a second later he felt it too as Twilight's marehood tensed and the alicorn mare surged far beyond the threshold. As Twilight's vision exploded into a starry sky, he couldn´t do anything than feel the same as the mare, her moist mare slit very much now also his. The alicorn´s cunning mind blank except for pure bliss. Wave after wave of pleasure rolled through her body as if princess Twilight was on a boat in a violent storm. He felt her strong inner vaginal muscles clenching over and over as the alicorn spurted thick strands of her scented marecum onto the floor and against his underside. Her hips bucked against the nothingness, desperately trying to grab a juicy cock that wasn't there, driving her deeper into the already numbing ecstasy of her orgasm.

Flash was stunned, tensed to the hilt and throbbing hard, but not yet ready to deliver another load of his life juice and with Twilight still lingering in her intense and prolonged orgasm, the momentary dead silence in the alicorn´s mind gave him the time he needed to finesse the situation apart.

Twilight had spoken of how he had performed his job better than two of his colleagues in the last few days, and now that Flash thought about it that way, it all made sense. Rose Petal and Candy Aura, two mares from the same battalion as him, the first an earth pony and the second a unicorn, had also been sent on secret missions in the last few days. With him as Pegasus, that made one pony of each kind and since the other two ponies were both mares and Twilight mentioned in her lust that he was the first stallion she ever "took", Flash was confident of having found his answer. In addition, he was convinced that if he still had the opportunity to wander around Equestria and ask ponies, he would end up with a total of nine other ponies, three of each kind, who had been called to the princesses for specific reasons or had been assigned other jobs involved with royalty.

Every year at the same time, when the mating season was approaching and most of the mares came into heat, it also hit the alicorns. Yet the alicorn´s weren´t ordinary equines but literal immortal goddesses. They needed something far more potent than simple stimulation to quench their sexual desires. They would summon ponies to them at precisely that time, one of each of the three tribes and presumably fuse them in exactly the same way as him, with their divine bodies. So that the alicorn princesses could assimilate every tiny part of the abilities and strength of their ponies they consumed and in the next year rule the kingdom with greater strength than ever before.

In spite of all his previous fear, his concerns of going missing, he felt almost content with his position. Perhaps it was influenced unduly by the afterglow of the most intense orgasm he’d ever felt, or perhaps this whole situation had messed with his brain, but he was almost excited at the prospect. This was something new! Unheard of! And though he couldn’t tell anyone about it… he found himself anticipating the next time he could feel something like that. A sense of security and belonging that underpinned everything as Twilight awoke from the aftermath of her waning orgasm, sat up, and soon after trotted out of the library. Ready to fulfill her royal duties to Equestria and her subjects for the rest of the year before repeating the secret absorption ritual of the alicorn´s for eternity the next year.
