In the late evening, the sun had just set behind the mountains; the herd was together in Celestia’s chamber when Tyler looked at a curtain which covered Luna ,Twilight and Celestia. While he did so he caressed Applejack while little Appleseed was already sleeping in her cradle.
Applejack leaned against his chest and enjoyed the many strokes over her belly,
“Ya got some new friends Ah see… that cat feller sure is an impressive creature… But do ya think a predator like him is able to live among ponyfolk?”

Tyler gave this a thoughtful nod,
“I will have to have a little talk with him. But he seems willing to behave for the time being, so I don’t see why we shouldn’t find a solution for that problem. Right now he’s with the other Rangers.”

“Well, ya seem to know what yer doing… I have faith inya, Sugarcube…” Looking over to the cradle, Applejack smiled gently before sharing that smile with Tyler. “Being together with the herd and everything seems so perfect. Ah love ya, Tyler.” While she was raising her head to him, he bowed down a bit to meet her lips, muttering a gentle “I love you, too…” into the kiss.

As the kiss ended, a certain flash happened behind the curtain and the silhouettes of Twilight and Celestia changed from pony form to human. Twilight harrumphed a bit,
“Brrrr… Quite cold without the coat… Luna?”

The Princess of the Night nodded briefly and after another flash, she came forth from behind the curtain. Twilight followed her, careful to hold her new balance. She was dressed in something matching her gala dress, only fitting for a human. AJ and Tyler now smirked and got up. Resting his hands on Twilight’s hips to aid her in balancing herself, he smiled down to her,
“You look so beautiful, Twilight…”

Looking down with a faint smile, the former unicorn blushed deeply,
“You… You mean it? I’m to your liking in this form?”

Tyler grinned and whispered something into her ear. It was inaudible for the others, but prompted Twilight to open her eyes wide, before she rested a hand on his chest, slowly pushing him away with a giggle and a seductive look,
“Maybe later, stud…”

Now Tyler’s look wandered over to Celestia, who still was behind the curtain,
“Come on, Celestia… Don’t be shy…” Coming behind the curtain, Tyler now carefully grabbed her hand and gently pulled her into the front.

“No, Tyler… Please don’t…” As she was in plain sight for everyone with wobbly steps and with her white clothes, she tried to hide herself with her arms as if she were naked.

“Come on… You know I won’t harm you…” Caressing her cheek he slowly went around her once and nodded. Like Luna before, Celestia’s human form was coming with some wings. This obviously came with being an alicorn. The sight caused Tyler to gulp. “An angel… You really look like an angel…”

Celestia, however, was visibly unsecure in this form,
“I… I want to change back! I feel so weak in this fragile body…”

Smiling gently, Tyler shook his head,
“Luna told me that you both studied the dispel spell from your mother, you can change back in an hour…”

Looking up like a frightened child, Celestia looked into his eyes,
“Why not now?”

“Because I want to do this with you…” In the next moment he gently pulled her in and kissed her, rested his hands on her waist. Celestia trembled ever so slightly. She was vulnerable and if they decided to do anything funny now, she couldn’t stop them. That made her afraid, but Tyler didn’t misuse this power. Quite the contrary, he seemed to intend to show her that there’s nothing to be afraid of.
“Beautiful like the dawn, ripe for the picking… An alicorn of light… of life and prosperity… One day, I will strip you off your clothing and tiara and will wipe away the last fears from you.”

Celestia gulped,
“Would you take responsibility as well?”

He nodded without hesitation,
“For as long as I live I will make sure that no newborn alicorn ever enters the path towards evil.”

This caused her to gasp and her pink eyes were locked into his blue ones. With greed she put her arms around his neck and pulled him in so her velvety lips met his for another passionate kiss. Again, time began to hold still as the Princess of the Sun blushed more with every passing moment.

After their lips parted, Tyler looked into her eyes again,
“Actually… there IS a thing I wanted to do quite some time now… And you look just right for it… Well, almost. Undress!”

Now Celestia was stumped,
“W-WHAT?!?”

With a grin, he undid the only button of her top, causing it to fall down and expose her firm and beautiful breasts. A short pull on her slip and the piece of cloth fell down as well.

Stepping away a bit, Celestia looked at Tyler,
“What are you doing? No! NOOO!!!!” As he approached her, she clenched her eyes together and went into a defensive stance, but he put her on his arms and carried her away. Struggling a bit, she didn’t dare to open her eyes. Was he heading for the bed with her? She wasn’t ready to- Her train of thought was ended abruptly by the silk touch of foam and warm water. One moment later, Tyler’s sigh was audible beside her. As she opened her eyes, she saw Twilight and Luna giggling together with Applejack as each one also entered the bathtub. Twilight caressed her naked body a bit with her hands to explore the abilities of these hands and fingers for a bit, the curiousity in her eyes made them sparkle in excitement. Celestia sighed. What a silly pony she had been. Or woman in this case. Tyler would never force something on her, why was she even worrying in the first place?

Tyler smirked,
“You look fabulous in this form, Twilight… Your human form really suits you!”

Looking down in embarrassment, the former unicorn blushed,
“Well… it feels different from being a mare… These breasts feel heavy when I stand.”

Taking seat at Twilight’s side, Tyler looked over to Applejack,
“You will learn that during sex, your body will be… Well, I don’t know… AJ, what body was more sensitive in your mind?”

The earth pony thought for a minute, smirked and nodded,
“That human form is far more exotic. It’s almost a new experience in having sex. The sweat, the finger nails to bury into yer pardner’s shoulders… These hands are so sensitive! It’s fun to grab stuff with them. But that’s only mah opinion…”

Celestia now cleared her throat,
“Can we change the topic, please?”

Leaning over to her, Tyler caressed her shoulder,
“It’s not like any of my mares gets forced into sex… As far as I’m concerned, whoever wants a foal… I’m willing to try and make her one… If you don’t feel ready, Celestia… That’s fine with me. I will wait for you to tell me that you’re ready.”

Caressing her throat and neck now he grinned,
“But I do have say it: This is a gorgeous body you’ve transformed into, Celestia. Quite a temptation…”

Luna was coming to Tyler’s side in the giant bathtub. “She’s curious about it, no doubt. I’ll see if she has wet dreams about-”
“Luna!” her older sister now snapped at her.

But Luna only stretched out her tongue and leaned against Tyler,
“Would thou mind washing my mane, Tyler? I like the feeling of thy fingers massaging me.”

“Oh, certainly…” While he washed Luna’s mane, he looked at Celestia. “I’ll have the reports prepared by next week, I think. Plenty of stuff happened… I would like you two to think of another spell in order for human and pony compatibility. The thing with Mimesis taught me that these spells could be misused.”

Luna and Celestia looked at each other for a moment before Luna closed her eyes,
“Maybe once winter’s done. But seeing what effect our human forms can have on thee, Tyler…” Below the water her hoof now gently tapped against his erection while she winked at him. “I say we keep those in store for…” She chuckled a bit and leaned at Tyler’s chest. “Thou know… spicing up our love life a bit…”

Tyler chuckled and began massaging her mane harder, causing more foam to build on her head,
“Luna you little minx…” Stretching out her tongue in good fun, the foam slowly ran down her closed eyes. Then, after Tyler was done with her mane, she dived into the water and ascended with her mane free of most of the foam.

After one hour of bath time Applejack and Twilight returned to Tyler’s chamber. Twilight, now in her unicorn form again, carefully held the cradle with Appleseed within her magic, since her way to carry the cradle was the smoothest and wouldn’t wake the foal. Tyler remained a bit longer at the door of Celestia’s chambers and looked to the two alicorns,
“It was a nice and fun evening spending the time with all of you together, Celestia…”

Taking her hand, Tyler bowed down to give it a short and gentle kiss. As he rose up again, the Princess of the Sun caressed his cheek,
“Would you… like to come inside my room?” Hearing these words from her sister prompted Luna to arch her brow.

Looking into her eyes, Tyler shook his head,
“You’re trying to be brave, Celestia… But still I have the feeling that there’s some fear in you.” With this he pulled her in and embraced her, groping her butt while doing so. His grip sent chills through her body and she secretly hoped he would knead her butt for a while.

Bowing down to her ear, he began to whisper,
“One day… I will take away your worries and make you-“

Closing her eyes, Celestia gasped and interrupted him with a whisper of her own,
“The mother of your children… Yes… Your brood mare…”

Closing his eyes, Tyler chuckled for a bit,
“I still hear your heat in these words… But if you’re returning to normal and this remains your wish… I will impregnate each of you girls.” The thought of a foal in her womb made Celestia shiver a bit, almost reaching climax, but she bit her lower lip and nodded for now before Tyler returned to his chambers to Twilight and Applejack.

Luna, however, arched a brow with a smirk. “Wish for a foal, sister… Wish for a foal…”

Snapping out of her daydreams, Celestia now opened her eyes wide,
“What? Lulu, you also wanted-“

“Yeah, and I would be expecting now if thou hadn’t interfered.” Luna said a bit grumpy.

Celestia sighed,
"I know… Maybe you’re better with these things because you’re not that used of ruling for all this time and not knowing what alicorns are capable of. I envy you, Lulu.”

Stepping closer to Celestia, Luna now casted the dispel spell, transforming her sister back to her alicorn form,
“I envy thee for these fond memories of mother, Tia…”

As both sisters now hugged each other, they closed their eyes,
“Let us promise one thing: We will raise these children, this new generation of alicorns together and will teach them all we know about harmony.”

Luna smiled as she looked up to her sister,
“No dark without light, no light without darkness. If our parents could give birth to us two, we are the living proof that Light and Darkness can coexist.”

Celestia now replied with a smile of her own,
“This is our most terrifying weapon, Lulu… This truth will send fear into the hearts of our enemies. We are the mares that combine Darkness and Light.” Luna now looked down, thoughtful. Celestia took immediate notice of this and approached her younger sibling at once. “Luna?”

The Princess of the Night frowned for a Moment,
“I just wondered… HOW did the ancient alicorns know about humans? I mean we both know that the future is vast and has endless options within each second… Tyler himself told me that his coming into this world was likely as a miracle. So… How did our ancestors knew about his kind?”

Celestia thought for a moment. This actually WAS a very good question,
“Well… if it comes to time and history… I think we should ask ‘him’, don’t you think?”

Luna arched a brow,
“Thou DO know that he’s not that likely to be found, right?”

Celestia now smirked,
“This comes with being the last of his kind… That and his eccentric ways… Actually I miss him a bit.”

Unimpressed, Luna arched a brow,
“I do not. The last time he was around I was a young mare and we defeated Discord. I remember him because thou spoke of him even centuries after his departure… which thou do not that often for a pony. But whenever turbulent times come, this stallion somehow always shows up.”

She then witnessed her sister yawn a bit and nodded. “Rest now, dear sister… I will watch the night…” After Celestia went into her chamber, Luna returned to her night watch. Speaking of this stallion could mean only one thing: Her sister expected things to worsen in the future. Otherwise she wouldn’t even think of looking for this stranger, this nameless stallion, who came and went as he pleased. Coming to think of it, he never bowed to Celestia either and behaved more like someone of equal stand… Maybe her sister liked that stallion for this reason above all. But, unlike Tyler, Luna remembered this stallion to be most picky about companions. Maybe he had some dangerous business to do… whatever it was he did. Shaking her head, Luna concentrated now and looked through the dark of the night to keep the evils of the night at bay.
