Chapter 1: I am your present.

I am your present.

Princess Cadance was enjoying peace for the first time in some time. In the fog of sleep, she silently thanked her loving husband for persuading her to wrap up all the important matters related to the kingdom making a window opportunity for a few days of total relaxation. No meetings, no document to rectify, no bickering nobles to squash under her hoof. Their lovely daughter was already in the care of Shining Armor’s parents’ so there was no need to extinguish any fire or repair any other sorts of magical damage. It was only them, stretching, Candace tried to feel her husband’s body only finding a free but still warm space next to her. At the same moment, she heard a low whisper in her ear.

“Let Eros out” – Cadance smiles hearing her lover’s quiet voice, relaxing a pink magical aura enveloping her body, changing her.

You see, there is a little secret to Cadance’s status as an alicorn something that few ponies knew about. When she or more precisely “Eros the Wild” the pink Pegasus with the biggest wing spans ever recorded ascended so long ago the changes didn’t end in becoming Alicorn. He became she and that started one of the hardest parts of Eros or Cadance’s life. After countless years of turbulences, self-discovery and thanks to guidance from Princess Celestia, the two personalities finally found a balance. Cadance becomes the dominant one because their new Alicorn body is female, with the promise that she will not forget about Eros’s begging and roots. She becomes an aspect of “True Love” while “Eros” becomes the wilder of “Desire”. This balance however had one flow, finding someone who would accept their two half was no easy task and over the millennia it became a constant battle that they lost many times, no matter what tactic they used Cadance and Eros were unsuccessful.

It all changed when their eyes fell upon a white fur unicorn named Shing Armor after one session of babysitting a young filly named Twilight Sparkle. There was something in him that Eros and Cadance attracted and exited like never before. Was it his absolute focus when he was on duty or when training recruits? Was it his build and muscular body that he worked so hard all his life constantly improving day by day? Was it his kind nature when he played with his little sister Twilight or when he took them on long walks around the lake during sunset or maybe it was his love for simple things in life like blueberry pie, or maybe it was all above and so much more? So, despite the advice from their aunt Celestia to wait for the relationship to develop and grow, they decided to show Shining Armor their true We earlier than usual. They just could not bear investing again so much emotion only to collapse just before the finish line leaving Eros and Cadance’s hearts shatter yet again.

The moment of transformation was one of the most nervous moments Eros or Cadance could remember, their decision to show their all to Shining Armor would make or break their future. They become so quiet, and Eros was sure that they scared their stallion after all they never hinted anything about their dual nature.

“Well, that’s not what you see any day” Shining broke the silence with his signature smile Cadance fell in love.

Eros was too stunned to say anything, a million scenarios were running through his head, anger, shouting, and disgust were all on the table but there was no hint of negative emotion. Only Shining calm aura and the fact that he closed his distance.

“Well, that wasn’t how I planned today evening but I’m a stallion of many talents” he said still holding his smile and giving his hoof to Eros which he gladly took.

What followed was one of the best nights of Eros’s life. Together they drink, dance, and play bowling games cursing uneven floors or poorly selected balls. They nail their hoof together when one of them strikes all pins and later at another bar have competition in assessing the booty of passing mares after too many apple ciders. And when it was time to part it was Shining Armor that initiated their first kiss, slow and tender but full of love. And at that moment their true journey through life started.

And now Shining Armor knew all the favourite spots of Eros and Cadance’s body, where and how to kiss and cherish and in return, Cadance and Eros would gladly return the favours. Eros’s transformation became easy as time went on and now only a whisper of Shining’s voice was enough, especially when he was putting a little kiss and nipping on Eros’s favourite spot behind his left ear. He could feel Shining muzzle moving slowly but steadily down his body, nibbling at his flank and when expected kisses came to fruition on his thigh Eros finally moaned. Yet his lovebird was still quiet, focused on kissing and massaging his left foot, moving up from his hoof slowly down and kissing all the way.

“Shiining” Eros meowed with a growing lust in his voice.

His plea was rewarded by Shining burring his muzzle in Eros’s sheath, taking deep breaths taking all Eros’s musk making him shiver. With a slow movement, Shining focus was on Eros’s balls taking each of them in his mouth and savouring them, while one of his hoofs was moving gently stroking his sheath building Eros’s erection. With another grunt, Eros could feel his lover’s tongue move up from his balls up to his building organ kissing all the way taking exceptional care of his medial ring. Shining gives only a moment for him to take his breath when he stop kissing his head and took most of his cock in one swift motion. Eros was melting, it wasn’t often when he woke up to Shining treatment not that he would ever complain about it. Cadance did enjoy giving Shining special treatment and Shining didn’t have a problem giving the same treatment to either Cadance or Eros, especially when it was harder for both of them to find time alone for each other and they needed just a quick moment for intimacy. But today Eros was in heaven, Shining tongue and muzzle felt different but so much better and the way he took his length. Eros, grunts again when Shining sucks harder his tongue dancing around Eros’s head only to deep dive all the way down to his base almost touching his balls and with accompanying lewd slurping noises coming from under the sheets almost making him explode.

“Shining… if you don’t stop this…” – Eros groaned in a brief moment when his Shining was taking care of his head with audible swallowing sounds.

“Oh we can’t have it my prince” – Eros’s eyes widened, that was a mare voice coming from under the sheets! He looks horrified as the silhouette rises and moves over him, giving his belly one small kiss and allowing sheets to move away revealing a white mare with piercing blue eyes that was hidden behind a few strands of blue and sapphire hair.

“Hello, my Prince” The mere purr while moving ever so closer to Eros, using her forelimbs to massage his chest while her back was stranding his bottom.

“I thought that you would enjoy my little surprise” mere continued with a faint voice looking at his stunned features. Eros looked again to his right searching for any sign of their husband finding only free space and an intruder to put her hoof on his muzzle silencing him.

“There is no Shining Armor here my Prince only Gleaming Shield, we can have all the fun you can imagine,” she said suggestively, stroking his muzzle and chin, closing the distance between the two of them while her bottom was slowly moving on his cock. Eros could smell and feel the mare somehow, she was pushing all the right buttons, mimicking Shining almost to perfection but there was a new feeling building inside Eros, anger.

How this mare dares to enter their chamber, how dare she look so like Shining trying to take his place! Their anger, Eros and Cadance’s anger became a sudden eruption of magic, and the mare unicorn didn’t have time to reflect on what happened. She was suddenly tossed to the ground with a wave of magic. Above her stood the Alicorn with hate in her eyes and with dark pink magic crackling all around them.

“Cadance, Eros it’s me, Shining!” – the mare called just before the alicorn attack.

“What?” – the double tone of Cadance and Eros’s voices asks, still looking at the mare dead serious ready to strike at any moment.

“We agreed that if you gave birth to Filly I would name her and if we got Fal you would name him” – That confession made Cadance stop for a moment, that was a specific detail in their marriage that they never shared with anyone. Still, she and Eros weren’t convinced, after all, they battled Changelings on many occasions. With a new detection spell designed by Twilight, they were still confused but not hostile, Shining the “mere” was still that a mare still looking sorry, guilty and slightly bruised.

“Why, how and again why” – Cadance asked sitting on the bed and keeping a close eye on the mere, feeling a headache coming on, this should be just a normal day just the two of them relaxing. The dark energy was slowly evaporating.

“Well, that was supposed to be a surprise” – Shining said slowly looking at his wife, moving to laying position on the carpet next to the bed after all she was still a little battered from her magical outburst.

“A surprise!? How on earth turning yourself into a mare without talking about it was a good idea of a surprise? What do you expect? That Eros would just clap the cheeks without question? How would you react if you woke up next to a stallion?” – Cadance asks with a hint of anger in her voice

“But you are already a part stallion” Shining tried to argue but the death stare she received was enough to stop her in her tracks. “Look…” – Shining said starting again – “I didn’t want to talk about this, because I didn’t even know that it would be safe and possible. So, I didn’t want to give up false hope. I’ve already had strange and embarrassing talks with Twilight and Celestia. After I knew that it was safe, I needed to use the remaining time to make sure that other ‘surprises’ were ready to make this whole ordeal even remotely worth it. That way you know” – She makes a gesture pointing at herself – “Surprise… Eros?” – she ended up pulling a small smile on her face hoping to ease the tension.

“And to answer your other question simply Twilight, Celestia and probably Luna. They managed to create a necklace that allows for that transformation to happen” she said showing that indeed there was a small moon-like necklace on Shining’s neck.

“But why?” Shining notices that Cadance is again Eros his eyes full of thought one hoof taping beside him on the bed.

“Because” – Shining started slowly moving next to her – “ It’s our anniversary” – With confusion on Eros’s face she elaborated further – “Of when you show Eros for the first time to me you silly” – Shining added, smiling when cogs in Eros’s mind finally started to spin, – “I know how much you like our little escapes and sessions when you were the dominant one when we are alone. But it became harder and harder to do things outside our chambers, there was always a slight chance of sprouting unpleasant gossip like ‘Shining Armor cheats on Princess Cadance’, ‘Shining Armor secret gay lover’” – Shining said with a bitter voice making quotation marks with his hoofs. – “Especially after marriage, we barely avoided catastrophe two years ago. When was the last time you could have some casual fun” – Shining asks pointing at Eros’s chest knowing full well that there wasn’t much of it.

“But why change gender, why go so far, why not just illusion spell” – Eros asks still trying to understand Shining way of thinking hoping not to sound ungrateful, it was kind of sweet of him.

“Because it’s clear that the so-called balance between you and Cadance isn’t working, you didn’t notice how angry you were last time when you mount me? You did leave a permanent mark on my crest that needs stitches. You become trapped in a golden cage and even if I love it when you are rough with me it’s still a cage Eros. Even Cadance mod would erupt from time to time, and I don’t mean pregnancy mood swings. I love you too much for allowing you to torment yourself like that” Shining said taking Eros’s muzzle into his hoof and looking at his eyes stroking him on his neck intended to comfort him.

Eros looks down knowing full well that Shining was right. He was trying to bury his part of emotion trying to rationalize it to himself, especially after Cadance gith birth. He thought that he was doing the right thing but now, looking back at some of his past experiences, he began to notice slight but unpleasant changes in their behavior and a scar on Shining neck was evident evidence that something wasn’t right.

“And remember illusion is just that an illusion but this, my sweet Prince, this body…” – Shining said, standing up making a small circle and showing it to Eros who could finally see her in full glory. That muscular body that Shining had was replaced by a beautiful, lithe mare’s form with muscles here and there, but they were delicate in their appearance. Eros noticed that Shining was now smaller than the alicorn and even his Pegasus form would easily tower over her, which was something he found refreshing, arousing even. Her new muzzle was also a bit shorter, narrower which would explain why their morning escapade felt different, more delicate. Her flank was a bit wider and curvier with a new cutie mark. Her long tail almost touched the bed and, unlike the previous one, it was larger and denser it moved back and forth in the air so sensually showing her marehood to him only to hide it a moment later. It is as evil as when Cadance did the same to Shining on so many occasions, so yes Eros did find Shining’s new body attractive.

“Is real, as real as a mare body can be, there is no way of detecting any anomaly, it will not break or end at 11th hours” – Shining said knowing full well what his tail did back there and was glad that Eros did check her rump briefly, with a smiled she considers it that a good sign. – “The only way to reverse it is by using the necklace or by a strong Alicorn magic, and that Alicorn needs to know exactly how to do it” - She ends up sitting beside Eros their flanks touching. – “Of course, if Eros is into meres. It was just my guesswork and intuition that I hope you would be into mares, after all as Eros you seem more dominant in bed” – Shining asked looking at Eros’s eyes moving her muzzle in his mane inhaling waiting for a reaction.

Eros did find Shining body exciting, to say the least, he forgot how long it was since he tried to woo Mare, for most of their lives it was Cadance who took the rains. Inspecting Shining neck with his muzzle he inhales her scent. After all, how he could say ‘no’ when it seems that Shining did put a lot of effort and thought into this whole ordeal, it would be a sin not to taste the effort of his work and she did mention others ‘surprises’ as well. Taking another breath of her it was a new experience of something similar to the smell of the ocean with a touch of a familiar smell of a unicorn that spends too much time with the army.

“I must say” – Eros said moving his muzzle to Shining’s tasting her for the first time – “That I’m intrigued and interested.”

“I’m glad my ‘female’ intuition was right, but I must insist my Prince, you must check me thoroughly” - Shining responded opening and inviting him, deepening the kiss.

They always make a little battle out of kisses like that, slowly building momentum, each of them trying to win over the other, their tongues dancing the tango of love and desire. This time Eros would not give up, with a swift motion of his forelimbs he grabbed Shining’s shoulder and pushed her into the bed trapping her under his body, attacking her exposed neck. He was already affected by her arousing smell and all that she had done earlier his fire was burning a new and her cute attempt at escape from his grasp only escalated his desire to dominate her. His bottom was moving back and forth with his fully erected penis between her udders looking for his price, precum was already leaking from his tip marking her belly with his essence.

“Eros…” – Shining call between another session of kisses, knowing full well what’s on the stallion’s mind, but also knowing that they needed to move out soon for her plan to work properly - “… darling please stop for a moment”

Eros did stop his advances looking at her questioningly after all, he could tell that both of them were enjoying it quite a lot – “What’s wrong?” he gasped, fighting himself not to mount her right here.

“There’s not enough time for you to properly and fully breed me, this will be my first time and I want both of us to take time to enjoy the moment” – Shining whispered into his ear making him blush and shiver – “However, I believe that we have enough time for me to finish what I started in the morning, and if you are a good stallion you will have a chance to return the favour in the shower.” – Shining said kissing Eros neck moving slowly down under his belly until she was meet with her price. Her eyes drifted closed at Eros’s tip with a quick lick enjoying his precum once again she started working on his cock.

“There you go,” Eros encouraged, moving his hips just a little moving his cook further into her waiting muzzle, there was no way he would try to stop her now, but a little encouragement wouldn’t hurt with one hoof on her head pushing her down.

“Mm mmmm.”

And once she started, Shining didn’t need much encouragement. It wasn’t their first rodeo after all, but this one feels special to Eros. Shining felt more deliberate her mouth did feel differently more divine. She was pushing herself down farther than usual her tongue dancing around Eros’s erection while one of the hoofs was massaging his balls. Eros was in haven, trying to keep his cool with one of his hoofs on Shining head trying to dictate the rhythm. Without prompting from Eros, Shining suddenly plunged all the way down on him sucking hard, taking him to the hilt. Eros’s whole body jerked, and he gasped deeply fighting his desire to explode. After a few moments of swallowing and sucking Eros’s cock, hoping for exploding end Shining pulled herself back up off him. Taking part his cock into both of his hoofs and stroking him, her tongue was dancing around his head while magic double her efforts on Eros’s balls massage, Shining knew that Eros was close.

“Shining… please inside” – Eros begged on the verge of eruption.

“As you wish my Prince” – With that Shining plunged herself down on Eros’s cock, all the way down, even taking some of his sheath into her mouth, her magic massaging his balls at the same moment, Eros push his hip up and grunted, feeling the first blast of cum already surging upward. Shining’s eyes close when she felt first of Eros’s cum visibly gushed into his throat. As a good mare, she drinks all that her stallion was giving her savouring the smell and taste, gulping it down moaning with every pulse of Eros’s cock against her tongue and throat.

After a few more jerks that reword Shining with another dose of cum, Eros finally free her muzzle with an audible plop and with another magic trick on Eros’s balls and penis another jet of hot spunk landed on Shining’s neck and chest decorating her white fur with Eros’s essence. Eros looks mesmerized at Shining as she collects more of his sperm from her muzzle and chest only to put a show of deliberately swallow it all showing how good of a mare she is.

“All clear, my Prince nothing will go to waste” - she purred at him mischief glaring in the bottom of her eyes. Eros couldn’t find a word still basking at the afterglow and performance his lover gave him. That was something they did discuss but never performed as much as Cadance like giving blowjobs the idea of making a show out of it didn’t quite land with her. To see Shining doing it for him was something out of Eros’s deep dream. Eros could hear his blood moving away from his brain to pump his penis again after what he witnessed and probably because of blood loss he also couldn’t stop Shining next move.

“Great Cum tornado attack!” – Was his only warning

In a moment Eros was caught in a titanic embrace of Shining love that had only one goal in mind. One body rubbing against another smearing their love juices all over their furs. There was no way of stopping or more importantly, Eros wasn’t able to fight it being caught off guard. It was the same trick Cadance used on Shining when he covered her body in his semen, and now he was on the receiving end. The cum was all over them, the sheets on his back on Shining’s flank or in their hair. The fight turned from tossing and cum exchanging to tickle competition and on that front, Eros has the advantage, his wing. Giggling and laughing the duo finally ended their fight on the ground while being covered in their juices tangled in their bed sheets.

“I’m really glad Shining, thank you, my love, I need this” Eros said allowing both of them to finally take a breath, kissing her on her cheeks.

“I’m happy you like my surprise, my Prince” – Shining said allowing him to take her into a loving embrace she was still hot down there but it was Eros’s day, and she would not spoil it with whining besides they still got time before needing to take the train. – “So do you want to help me with the shower?” – Shining asks finally freeing herself from the sheets failing to correct her hair, putting her new necklace inside the bedside cabinet and locking it with a spell.

“With pleasure my love, you could also tell me more about why it seems that we are on a tight schedule despite your promises of relaxing” – Eros asked, following Shining into their bathroom turning the shower on and allowing her to enter first after all there was still a price hidden behind that lovely tail and Eros will not miss the opportunity.

“We have received an invitation to this evening’s gala in Canterlot from Princes Celestia but before the ball, we need to visit the spa and pick your suit darling” Shining told simply taking a shampoo and with the help of magic rubbing it into hair winking at Eros.

“Wait, what gala, what suit, spa the best spa in the whole Canterlot? I don’t remember receiving any invitation… Shining what did you do?” – Eros asks squinting his eyes to avoid bubbles that she tossed at him.

“Ohh silly me, invitations are for Eros Wild and Gleaming Shield. I’ve booked a spot for us in the spa for relaxation time and to make us more presentable and a friend of Twilight Rarity was kind enough to prepare a few suits for you and me to choose from after all I knew your size.” – Shining said as if it was the most normal thing in the world

“Wait… Gleaming Shield” Eros said looking at her, receiving a nod of confirmation from Gleaming – “and Eros the Wild?” – Eros asked with mischief in his voice only receiving a spank in his nose by Gleaming tail that briefly reviled her pink marehood winking at him.

“Oh, I can be Wild” – Eros said, a bit surprised that Gleaming could control her vulva that way, after all her smell didn’t show that she was in season – “Celestia did give me some pointers during our test runs” – Gleaming admitted as reading his mind, for the first time there was an embarrassment in her voice but she did nothing to stop his advance. Nibbling on her flank he slowly moved his muzzle under her tail giving her a first quick lick tasting her nectar that was already there. With slow circular movement, Eros’s work was rewarded by Gleaming moans, so he pushed forward with his tongue into her depths. At the same time, Gleaming felt a wave of magic on her body, especially on her crest, cutie mark and base of her horn. She knew exactly what Eros was doing with that spell and she loved every moment of it the slow tingling feeling washing over her in a pattern that she loved. Gleaming breath became irregular punctuated by quiet moans of pleasure that made her lover happy and more eager to please her, and there was a new feeling building inside her depths. Something alien to her, with another jolt of energy around her body and Eros’s sudden switch to her most sensitive clit her body jerked back urging for more and he was happy to oblige. Eros doubled his effort the moans and Gleaming pleading were a clear indicator that she was close, and he was doing an excellent job, with one final lick and combined magic on her sensitive part he pushed his lover over the edge.

Gleaming went absolutely still and quiet. For that brief moment, everything froze and then it hit her, like a raging bull or a thousand small needles she had no way of proceeding with all these new feelings that were bombarding her head at once her first female orgasm. It was so unique experience from what he was used to and the amount of different signals and unstopping attacks from Eros’s tongue and magic made her almost blackout. Her body suddenly collapses, jerking against the restraints of Eros’s magic so as not to fall on the bathroom floor.

“Shining, Shining please wake up…” – Shining heard Eros’s voice as if through the fog, her consciousness slowly returning to her, and Eros’s features once again became clear.

“Oh, sweet Celestia I’m so sorry Shining I’ve…” – The rest of Eros’s apology was cut short by Gleaming‘s muzzle joining with his for a tender loving kiss washing away concern.

“So that’s how it feels like, now I know why Cadance loves it so much when I return the favour” – Gleaming said slowly, taking a few deep breaths and looking at Eros with a smile on her face.

“But… but I thought that you and Celestia…” – Eros starts only to be silenced by Gleaming hoof on his cheek. – “I’m only yours Eros, Cadance, not Celestia. She helped me with some aspects but I want you to be my first in all those special moments we will share from now on, it was for you Eros that I decided to change myself, and I love every second of it, thank you my Prince” – Gleaming said kissing him on his nose.

“I, I also enjoy our time today Shi… Gleam, my little Princess” – Eros confesses allowing himself to be hugged again by a smaller mare somehow knowing that it was the beginning of another fascinating journey for both of them, just like when he showed his true We all these years ago and Shining smiled and accepted them all he would accept Shining Armor as Gleaming Shield.

“Now my Prince help me with the shower we have a train to catch” Gleaming said with a familiar smile plastered on her face that Cadance and Eros love so much.

“Yes ma’am”
