"Ah!?... C-come in..." The voice of Celestia Reached Starfall who promptly pushed the doors open and entered the Study.

As soon as he was inside, he noticed a flustered Celestia looking at him with a an embarrassed but happy gaze, yet under it he could see an underlying hunger, and If he didn't know Tia as much as he did, he probably wouldn't have noticed.

But as it stood, he quickly approached the Princess and gave her a warm embrace in greetings.

"You called for me Tia. So here I am." He said looking her in the eyes which she returned almost getting lost in his mesmerising purple irises.

"Y-yes that's right..." She lightly shook her head to drive away the invasive thoughts. It wasn't the time for this..."A threat appeared over Canterlot. Multiple unidentified hostile figures had been detected close to the borders and the City went into lockdown. We were hoping you'd know a way to at least identify if not fight off the offenders. Canterlot might have it's defences and army, but if it comes to magic and knowledge I'm unashamed to say that we aren't a match for you and you wouldn't lack in comparison to old Starswirl." Celestia said reminiscing her old teacher and the greatest magic researcher in Equestrian history.

Starfall felt quite moved by the praise as his cheeks reddened. It took a lot of time and hard work for him to reach this level, So for Celestia to compare him with Starswirl and even alluding to having surpassed him was quite a big deal in his books.

"Thank you for you vote of confidence Tia. You can be sure I'll do my best to help you. Now please tell me what you can about those beings..."

"...That's not a lot really..." Said Starfall after the duo sat by the coffee table and Tia explained the situation.

"Yeah...I know...Do you have any ideas though? " She asked hopefully, and Starfall noticed something interesting about her. Having experienced the physical change her Alicorn magic induced in her, Celestia became more younger looking to match her lover, ergo him. But that was the more obvious change. What caught his attention was her slightly more youthful outlook on life and overall behaviour. She might still act like Celestia of old, but he could see some signs that suggested she felt less burdened with the long life she had lived. He wasn't sure whether it was her magic making her more youthful mentally to match her physical appearance in turn, or it was thanks to his own influence and the return of her sister which allowed the princess to enjoy her life once more with a renewed vigor. Whatever the case was, he felt happy for Tia, because all he wanted, was for his girls to be happy...

Starfall closed his eyes in thought and hmmed. While he already knew the identity of the attackers, he still preferred to keep his meta knowledge a secret so he thought of other possibilities that could be behind the mysterious figures.

"Well, from what you have told me it could be a number of things...While the fact our mysterious beings are pony shaped does narrow the possibilities, it still leaves quite a number of possible culprits." Starfall said and Celestia nodded.

"Do you have any guesses?" She asked and Starfall nodded.

"Well... assuming our targets aren't some kind of black clothed spies from a hostile nation or some group of terrorists, we could assume the black coat is their natural colouration. Add to it the smaller stature, and I'd say there are only really two possible groups of creatures that would match the description, one of them mutch less likely seeing as they had been sealed in a magical prison for over a thousand years, so that leaves..." He got silent for a moment building up the tension as Celestia looked at Starfall in anticipation.

"Well?..." She asked and Starfall relented.

"If I had to guess, I'd say we're currently surrounded by an army of Changelings..." Starfall revealed grimly causing Celestia's eyes to widen.

It was quite funny to see Princess Celestia going in a circle panicking about the current threat. It was clear she wasn't the calm leader everypony thought her to be, at least not behind the closed doors. It was obvious she had trained in acting as a leader but inside she was still just a mare doing her best for everypony. He felt quite flattered that she trusted him enough to show him that rare side of her.

But there was no time to appreciate the sight, so Starfall approached the panicking Tia, and hugged her to ease the growing tension. It was clear she was worried so it was only natural for him to do his best in calming her down.

Tia flinched upon finding herself in his embrace, but when she realised what was going on, her emotions finally calmed down slightly. That's right. Starfall was here and she didn't need to worry.

Her body slowly mellowed down in his embrace as she sniffed his mane. There was no mistaking it. He was her Starfall, and not an impostor. Her memories flashed to the far off past when Equestria suffered from the occasional Changeling attacks. kidnapping and impersonating your loved ones only to suck all your and their love, leaving dry husks. It took a lot of work to banish the creatures from their lands, a lot of it being the work of regular guard patrols passing through every town looking for the foul beings. It was a dark time and Celestia having lived through it understood the fear of one day finding you loved ones taken by one of them. From all the monsters haunting Equestria, Changelings had taken their rightful spot as the Equestrian version of a Bogeyman.

Starfall also noticed the unusual behaviour of Celestia, but he quickly understood after remembering what the old records said about the creatures. Tia must have been quite affected by them when their attacks were still a relatively common occurrence.

"W-we need to do something Starfall...We can't let them...we can't let them return...I...I..." Starfall was surprised how intensely Tia reacted, there must have been some story behind it, but for now he needed to reassure her that everything was going to be alright. He decided to expose some things he'd rather have stayed hidden.

"It's alright Tia. Look at me. You don't have to worry. If we're facing Changelings then there is really no need to panic. I didn't want to tell anypony about it but...I actually met a changeling recently." Starfall said, causing Tia to perk up in worry.

"You did what! Starfall! They are evil! They...They..."She was getting worked up. Yes it was clear that it was more personal for Tia. Maybe she lost a friend in the past or something...

"Calm down Love. I was the one who discovered him. My mage sight can actually see through their disguises because their magic is different. We had a long extensive chat, with the Changeling being very much unable to do anything, if you catch my drift." He said making Celestia relax as a hint of curiosity appeared in her expression.

"What did you learn then?" She asked, and Starfall smiled.

"Well, for starters, the changeling I caught was a loner that abandoned the hive. Apparently They are led by a Changeling Queen named Chrysalis, and live in a far off land called the Changeling Kingdom, that isn't really much larger than Ponyville only consisting of a large hive mountain surrounded by a desolated plane. I also learned a lot about the Changeling physiology after getting permission from the Changeling to study him." Starfall explained confusing Celestia.

"You asked...permission?" She asked and Starfall smiled wryly.

"Well. After interrogating him, I found out he wasn't really a bad guy. He never kidnapped anypony and only lived of the Ponyville high accumulation of "Love" and occasional small feeding on the passer-by which never went above any noticeable level for the ponies involved. And I assure you he was speaking the truth as I made sure of it with magic. Kevin disliked the way Chrysalis led the hive, and simply wanted to live his life in peace. We actually started getting along pretty well afterwards." Starfall shrugged while Celestia tried to process the newest information.

"Starfall...Are you sure that...He isn't just manipulating you?" She asked worried and Starfall sighed.

"Tia...I can see this topic really impacted you. But I can assure you, there's no way a weak drone Changeling like kevin could even scratch my mental shields. There's many dangers in Equestria Tia. Mind control being just one of them and I can assure you, I took steps to protect myself from most of them. So when I say that a Changeling can change, I meant it. No pun intended." He winked, and Celestia visibly deflated i relief. He doubted she'd trust a changeling any time soon, but he knew she trusted him, so if he said it was alright then she would believe it.

"So...Did this "Kevin" taught you anything else?..." She asked after a while and Starfall laughed awkwardly, looking away in embarrassment.

"You know me Tia haha...A new fascinating specimen...I'm probably the most knowledgeable Changeling Researcher in history of Equestria right now. If this threat really comes from their direction, I assure you my Princess, you have completely no reason to worry your pretty little head about it." He kissed her muzzle and Celestia finally completely relaxed.

Her body slumped onto the soft carpet in visible relief and she smiled at Starfall.

"Thank you...I...I don't think I've ever felt so calm before any similar conflict. Whenever I'm with you I...I just know that...that everything is going to be alrighty..." Celestia smiled up at Starfall who walked over and sat in front of her.

"I'm sorry I wasn't there before in that case." He said while brushing her cheek and she shook her head.

"Silly, don't say such things. And if you think about going back in time to help, just to make me smile, better stop that train of thoughts now, are we clear?" She said in mock anger, making Starfall laugh a bit awkwardly. It's true he thought about it, but there was no feasible way to accomplish it that wouldn't mess up the timeline...

"Crystal." He replied and Celestia snuggled into his Chest, her horn laying gently on the side of his neck as he leaned down to kiss the back oh her neck.

His hoof gently caressed her side, eliciting small shudders from the Princess as her breathing slowly became more erratic.

"Starfall...mmm..." She moaned quietly and Starfall finally noticed that one of Celestia's hooves was currently placed firmly between her hind legs...

He looked down at her and she looked up, their eyes meeting and a small smirk appeared on the face of the stallion as Celestia face became even more crimson.

"Well, would you look at that." He whispered playfully as his hoof gently caressed down the beautiful leg that ended inside a certain warm place.

Celestia Shuddered and bit her lip as his hoof finally reached the bottom and gently passed her own white hoof, touching her most precious spot and eliciting a shudder of pleasure from the Princess.

She was already completely drenched, obviously ready for the Stallion.

Her eyes looked at Starfall with a clear hope and Starfall wasn't one to refuse a mare that he loved so much.

Something was already raising and it was not a Shield Hero...//sorry//

Celestia opened her eyes wide when she saw it. Despite having seen it on multiple occasions, She still couldn't get used to the size of this thing. She suspected it had something to do with Starfall's magic. Who said only Alicorns could alter their bodies subconsciously. Starfall was certainly powerful enough that the same wasn't out of the question for him...

She didn't even realize when their position changed but as her flank raised into the air in invitation and she felt his strong hooves get a hold of her back, she could only feel a spike of arousal and couldn't wait for what came next.

She didn't have to wait long though, as soon enough, the enormous member parted her lower lips and went straight into her vagina with a single thrust, her walls instantly clenching on the shaft as the first orgasm of the night impacted her body the moment of penetration. She instantly went limp as her wings spread in a magnificent wing boner. Soft moans of pleasure escaping her lips.

She didn't have time to recover. Starfall giving her no reprieve, assaulting her pussy thrust after thrust like a wild animal. She felt amazing, nothing mattered in this moment as the Stallion made her his and his alone. She would never be able to look at any pony the way she looked at him. He was her only one. Her Special Somepony. The one who owned her everything. She wanted him to go faster, to really assert his dominance. For once in her life she didn't want to be the leader. She wanted, no she needed more.

"Ah! Starfall! More! She screamed in pleasure, and Starfall was more than willing to give it to her as he plowed at her pussy in wild abandon.

At one point Starfall actually hit on her womb and Celestia once again shuddered in orgasm. With her larger stature, even when his Dick was enormous it usually wasn't enough to go past that ultimate barrier but somehow she felt like if they only tried a little more, they might actually succeed. So with no uncertain feeling Celestia asked Starfall to push her even harder and he listened. Her face impacting the mattress under her as Starfall turned her into his plaything mashing and pistoning into her like an unstoppable buffalo.

His shaft started to poke at her womb with strength and purpose and finally Starfall couldn't take it anymore as his first orgasm approached, and loosing any thought of going easy, pushed his shaft all the way through her cervix and into her womb.

Her eyes went wide and for a moment all she could think about was the incredible pleasure that assaulted her body.

It didn't took either of them much to recover though, and soon enough the two powerful ponies went back to their intensive lovemaking.

A few hours went by since the two started and they were now snuggled in the hammock set up on the balcony, looking into space and talking about simple nothings.

"...Love..." Celestia suddenly whispered and Starfall replied.

"...Yeah?..." He asked and Tia turned to look at him a bit more seriously.

"There's something I wanted to talk with you about..." She said and Starfall nodded.

"I'm listening." He said.

Celestia took a deep breath and collected her thoughts.

"It's...Well... Twilight. and to a lesser extent you... What I mean is...I... I've been watching both of you for a very long time... There's a certain Spell...An unfinished one. In this book." She said, with a small flash summoning a very old looking notebook covered in star.

"I originally wanted to give it to Twilight you see... This Spell...It might very well be able to make her into an Alicorn If it's actually finished, I think... But before that I wanted to test her somehow. make sure she really deserved it. That she was ready for what it entailed." She said waiting to see Starfall's reaction, but he just nodded and waited patiently for her to continue despite his clear interest in the notebook.

"Well...That was my original idea but...Now, I was hoping to ask you for your opinion. After all, You were also one of the candidates for receiving the notebook. And I trust you to understand my reasoning and, add supply your own arguments that might help me decide." She explained and Starfall smiled at her with genuine care.

"Thank you for trusting me with this...I...I actually think your original idea was pretty good Tia. As for me receiving the Spell...Well, I'd certainly find a use for it, even if I wouldn't use it on myself, but I think it would loose the meaning you wanted to impart through giving it to Twilight. I'd treat it just as another magical curiosity after all. There's also the part where I want to achieve higher power relying on my own strength... I think, this spell would be like cheating for me personally." He said with a wry smile. And Celestia couldn't help but chuckle.

"If it's you, I'm sure you'll be able to do it Love." She said and Starfall couldn't help but kiss her on the lips making her giggle.

They were soon back to the stargazing as Celestia send back the book, now much more reassured about her idea.

"So..." Starfall said, not looking at her and she replied similarly.

"So..." She said.

"Aren't we supposed to like...watch out for some invaders or something?" He asked and Celestia opened her eyes wide.

"Sweet Sunbeam Pineapple, You're right!" She exclaimed jumping out off the hammock and running to her Telescope.

Starfall chuckled and walked over to her calmly, as she was quickly changing the direction of her looking glass.

Gently caressing her back he reassured her.

"Calm down Tia. I'm sure they won't be able to go through the barrier If their Queen doesn't come here herself. Quite the barrier that is by the way. I was honestly impressed with it when I saw it.

Celestia calmed down a bit and looked back at Starfall.

"You're right. It is pretty amazing all things considered. And you'll be surprised to know that Shining Armour was the one to create it using his Talent in protection and...well...shields... to its greatest benefit." Celestia said sounding quite excited and proud.

"Truly!? That's amazing! I hope we can meet with him soon. I'd love to ask him about it over some tea. Especially since Twilight had been a bit open to the idea of children and I'd love his opinion about it..." He said blushing slightly.

"Aren't you going to propose to her first?" Celestia asked and Starfall laughed awkwardly.

"You know Tia...I wouldn't mind getting married to all of you. I assure you." He said caressing her cheek and making her blush at the thought.

"But...?" She asked a bit worried and Starfall smiled.

"But...I don't think it's the right time for it. What I mean by it, is that there's a lot of things going on, and I have a feeling more is still going to happen. Love. I assure you. I'll marry you all in a heartbeat. I just want to make this world the safest place for you before we make it all official and share it with the rest of Equestria..." Starfall explained and Celestia felt like she understood his sentiment. though something made her look ay him suspiciously.

"And you aren't doing it to leave place for new herd members?" She squinted her eyes and Starfall felt like a Deer caught in the headlights.

"O-of course not love!...Who do you take me for..." He said looking away with a small blush. He really didn't plan on adding anypony to his herd...but life had a tendency of making plans obsolete very quickly when the actual time came to execute them...

"Well speaking of Marriage..." Celestia said giggling at Starfall's reaction, not offended by anything that was said. "You'll be surprised when you speak with Armour I assure you. Especially with what's happening in two weeks."She giggled not elaborating, and had Starfall not known the original future of the Show, he wouldn't have had any idea what she was talking about.

But as it stood he just gave her a confused look and internally sighed. So the Canterlot wedding was two weeks away? Good. Chrysalis won't know what hit her...Maybe he could kidnap her?...That would certainly stop her plan from coming into fruition...But what then? Dump her inside the Lab beside Discord? Actually...That doesn't sound bad. Though being a psychiatrist for the notorious Equestrian villains wasn't his favourite idea of spending his Sunday afternoons...
