Author notes:

Alright so today I found out about the Sailor Moon rare pairing week event on tumblr and My God did I got excited.
I had been thinking about pairing Mamoru/Endymion with Kakyuu for a while now, yet I was not so sure exactly how to do it. To be honest, after writing this, I am now a huge fan of the couple!

The prompt for day 1 was Past/Future. Hopefully I can write something for each day of the week *crossed fingers*

Hope you like it!

"Your majesty?" A pair of sweet green orbs peeked through the slightly open door of the main bedroom, finding that Queen Kakyuu had already woken up and left her chambers.

Sailor Star Healer left the royal wing, her high heel boots echoed as they slammed onto the floor tile. She was known to be noisy and some of the castle workers would rather flee from her way as they heard her come.

She crossed through a glass catwalk that connected two of the six wings the royal castle had. That path allowed her to see the private gardens of her queen, which were the home of the Kinmoku magical flower: the sweet olive.

And there she was, collecting a bouquet of those flowers into her wicker basket. Healer sighed in relief, she had been looking for her for what felt like forever. She decided to jump from over the crystal fence of the catwalk, taking advantage of her abilities as a sailor senshi.

"My queen, I've been looking for you everywhere"

Kakyuu did not raise her head to acknowledge Healer's presence, putting all of her attention into her garden duties.

"I know you said you didn't want to be interrupted but I come bearing news from the intergalactic transportation station. Prince Endymion is here."

Her queen dropped her basket in surprise and finally decided to look towards Healer, begging with her eyes for her to reconfirm that what she had heard was true.

"He is waiting for you at the main studio."

Once Kakyuu reached that room, she felt like her legs were going to give up. She asked Healer, who had escorted her all the way there, to let them speak alone and gave the order not to be disturbed at all.

When she opened the huge wooden door, she quickly found Endymion's back as he was looking through the huge window made of stained glass. When he turned around, following the door's noise, he greeted Kakyuu with a light smile, making her heart skip a beat and sink down into her stomach at the same time.

─── ･ ｡ﾟ : *. .* : ﾟ. ───

Endymion had become the King of the new Earth a few centuries ago.

He had not hoped for the future that was once shown to him to ever come. Usagi had decided to flee Earth to follow Sailor Star Fighter and she had made sure to let them know she was never going to come back.

So that was it, the future was done.

He thought he would end up living his life as another human being on Earth for a few decades, he thought of getting married and maybe having one or two children. He would practice medicine, do his best for his patients, and overall he would try to be happy with whatever he had left after Usagi's departure.

He missed her like crazy, knowing for a fact he could never love anyone like he loved her ever again.

But, albeit the future is built on the choices we make, there are events that we just can't escape from. One random day Elysium called for its prince and he was absolutely not ready for it.

"The golden crystal is finally ready to release its power. It will heal the Earth from within and it shall be the beginning of a new era" Helios had told him. "It's time to fulfill your true destiny."

The beginning of the new kingdom came with resistance, as any change does. He missed Serenity like hell all those years, sometimes cursing her for leaving him with the responsibility. He knew he was being unfair, Usagi had fallen for another man and she was within her rights to do so, but he had imagined the future to be so different from what he was now living.

He needed help. Some of the sailor senshis had remained loyal to his kingdom, some other only wished to live their own lives alone. It had been Rei who had given him the idea to reach out to Kakyuu.

"She knows what you're going through as a ruler of a planet and as someone with a broken heart."

"Kakyuu and Sailor Star Fighter…?"

"Yes. Kakyuu had chosen Fighter to be her consort as she was getting ready to ascend to the throne. The wedding had been already planned out when Usagi and Seiya decided to run away together."

So it was only natural to bond as quickly as they did when they decided to meet each other. Kakyuu, who was already married and crowned too, helped him get a grip of his new role as King. They even formalized a new cooperation agreement between Kinmoku and Earth that brought prosperity to both planets, thus marking a new beginning on intergalactic alliances. The solar senshis and the new star lights, led by Healer and Maker, turned into the most efficient army of the galaxy, bringing peace all throughout the Milky Way.

Kakyuu and Endymion became friends and allies, confidants and accomplices, and the most respected (and feared) dupla of the galaxy.

─── ･ ｡ﾟ : *. .* : ﾟ. ───

Endymion was seated with his legs crossed across from Kakyuu, finishing his sweet olive tea, a beverage he could only drink in Kinmoku.

"So, you've found them?" Kakyuu began to talk, she needed to know.

"Yes. They are based on this forgotten satellite called Sycorax." Endymion informed her whilst finishing the last of his tea, slurping some flower pieces that remained on his cup.

"That's… in your own solar system," Kakyuu recalled. "Nearby Uranos?"

"Yes, exactly. Sailor Uranos herself helped them with accommodations after the last time they were discovered by our troops. They are on their way to apprehend them as we speak."

Kakyuu couldn't help but smile. They had been fighting for so long now.

If anyone had told them Sailor Moon and Sailor Star Fighter would end up being their very own opponents, she would not have believed them. But there they were, about to win the war against the only people in the galaxy to be able to face them.

Endymion and Kakyuu's alliance had brought new systems, new culture and new laws into the planets of the galaxy that had societies in them. Some of those planets refused to align to the new galaxy way of being and thus some of them had begun to riot against them. Soon they realized most of them were being led by Sailor Moon and Sailor Star Fighter.

Traitors… both Kakyuu and Endymion had been enraged. Had they not left away to live their own lives alone? Why would they try to take the power they once denied?

Kakyuu tried to read the serious look on Endymion's face. He was being more cryptic than usual and that was getting into her nerves.

She had fallen for the Earth's king rather fast. It was like she had been starstrucked by him, by his gallantry, by his imposing way of being. However she was married, though her consort was really a nobody that had only been used for her to access the crown after Fighter's departure. She had wanted to leave him for so long but divorce was not an option just as the tradition of her planet dictated.

Endymion, on the other hand, had never gotten married. It had been his decision to remain a lonely ruler, though he was known to hold many lovers at the same time. Kakyuu and him had talked about it sometimes and she had soon learned that Endymion had never really gotten over Serenity.

That fueled even more her disdain for Sailor Moon.

"Are they going to be sent over to Earth? Or are they going to be sent to the prison at Nemesis?"

Endymion smiled at her with conceit.

"I haven't decided yet. What do you think we should do?"

Kakyuu stood up, her turn to look into the window to the sunset of her own planet.

"Nemesis was built for people like them."

She gasped when she felt Endymion right behind her.

"Are you okay? You seem… off tonight." He asked her right into her ear.

What could she really say? That she had been afraid he would try to take Serenity back to Earth with him?

She even hated the idea of them seeing each other again.

"You know, I came here because I wanted to tell you about their apprehension in person. I thought it would make you happy."

"I am… glad this fight is finally over."

Endymion then grabbed her by the shoulders, making her turn to face him. His eyes now had a darker color, like liquid obsidian.

"I also came here because I was also thinking you might want to celebrate with me."

Kakyuu held her breath, her head spinning, her legs giving up. She tried to keep her cool and used his arms to hold herself up, digging her nails into his skin.

"What do you mean?"

"You know what I mean." He answered with a deep voice. "When was the last time that husband of yours took care of you?"

Kakyuu couldn't help but to squirm right in front of him.

"I see." Endymion celebrated with a disarming grin. "If you let me, I can help you out."

She couldn't speak but she knew her body was having a mind of its own, moving closer into Endymion's arms that received him into a strong hold. He wrapped his cape around her and leaned down to kiss her hard.

Queen Kakyuu smiled against his lips, in between kisses, while his hands were fast into undoing the laces of her corset. Suddenly Endymion turned her around so he could kiss her shoulder blades as he worked to get rid of the rest of her clothing.

"You're a vision." He mumbled as he got to see her wearing her golden lingerie. Her bra cupped her pale breasts yet it was transparent enough for him to be able to see her pink nipples. "Just like I thought you were."

"You've… thought of this before?"

"Yes. So. many. Times."

Endymion quickly unclipped his cape and got rid of his mask and his jacket. Kakyuu licked her lips as she watched how the Earth's king removed the rest of his outfit.

"I have too" she confessed as she laid herself into the living room table, offering herself to him as a human sacrifice.

The prince leaned down again to kiss her deeply, Kakyuu feeling his warm skin against her now. He began to kiss her neck whilst his hands were now cupping her breasts with force. Following down the path of her body, Endymion kissed her collarbone, then her shoulders and then his lips traveled into the valley between her breasts. In a quick smooth move, he unclipped her bra, setting them free.

Kakyuu moaned shamelessly when his lips began to suck one of her nipples. Her head going into a frenzy.

"I love the way you sound." He said as he moved into her other nipple.

Kakyuus legs were already trembling and found stability as they wrapped around Endymion's waist. He smiled as he felt the humidity of her center.

"Oh honey, you're so ready for me. But not just yet." Kakyuu gasped with anticipation. "First there is something I've always wanted to do."

Endymion crouched in front of her as he got rid of her golden lace panties. He slid her towards him and opened her legs, quickly leaning down to savor her. Kakyuu moaned again so hard she knew the whole castle would hear them.

Good, she thought, she wanted the whole galaxy to know what Endymion was doing to her.

His tongue quickly found a steady rhythm against Kakyuu's sensitive button and smiled against it when he began to feel how it was getting bigger and bigger. Still using his tongue he decided to put his fingers into her as well, making her growl with pleasure.

"You are taking it so well."

"Endymion…" she called for his name, not sure what else to ask of him as he was killing her with pleasure. "Oh, God, Endymion."

He followed through, going faster and harder, until she felt her insides contract with such force his fingers got trapped. Kakyuu was moaning like crazy, calling his name over and over again as she came.

When she finished riding her orgasms, he took his fingers out, licking what had been left of them from her.

"Amazing"

He stood up and gazed down at Kakyuu, who was trying to breathe normally again. He felt so lucky to have been able to taste that woman, queen of Kinmoku, holder of the power of the fire crystal.

He had not been honest with her for so many years, acting like she was only her ally. He had realized early on their alliance that he had fallen for her like an idiot.

He had been so scared to be in love again so he decided to keep it stored away within his soul. However, He had to thank Serenity for opening his eyes. When he saw the footage of her and her lover, living their best traitors lives, he had decided to take the next step with Kakyuu as he realized he deserved to be happy again.

He sat on the couch where he had been drinking his favorite tea just a few moments ago and reached for Kakyuu. She quickly understood what he was asking of her and stood up from the small table.

She positioned herself on top of Endymion, her legs around his, and crouched into him. Endymion was now the one moaning into her ear as she rode him with a steady velocity. He helped her move deeper, guiding her with his arms around her waist. As she kept on moving into him, he slid one of his hands up to her neck and pressed lightly.

"You're mine." He said, not asked. Kakyuu nodded, her cheeks red and warm.

"Yes I am."

"You're going to come home with me."

"Yes, yes I am."

"And we will rule together, forever."

Kakyuu gasped as she felt she was getting closer again, going even faster and deeper.

"Oh honey, you are amazing." he mumbled with a trembling voice, letting her know he was close too. "Keep going, you can do it."

"Oh, Oh, God!"

Endymion held her in place with force. He wanted to feel her contract around him as deep as he could, which was more than enough to make him finish too. They both moaned in unison into each other's ears.

─── ･ ｡ﾟ : *. .* : ﾟ. ───

Healer stood up to take the kettle out of the induction stove, leaving Maker alone at the dining table while she surfed the internet with her tablet. The silver haired senshi turned around as Maker suddenly gasped from her seat.

"They've got Seiya…"

"No way!" Healer quickly ran to see the news for herself. "What about…?"

Maker bit his lip as she kept on scrolling down, trying to read as fast as she could. However Serenity had not been mentioned at all in the article.

"Do you think she was able to escape?" Healer asked, worried to the bones.

"We can only hope, let's wait to see if she can communicate with us soon. If she really managed to escape then she will be trying to free Seiya as soon as she can."

"I'll call Uranus to let her know we are in for whatever she has planned."
