That's the end... I know I'm late but it's so weird to finish it all after a month of hard work! I hope you liked reading the prompts as much as I liked writing them!

Thank you for reading and enjoy!

A young man sat on a bench in Fukuoka Airport, looking nervously at his left and his right. He had long black hair with a few strands of silver hair and bright arctic blue eyes. He appeared to be tall, square shoulders and muscular.

"… When are they going to arrive… Nii-san, Yuu-chi…"

He was about to bite his thumbnail when he felt a pair of hands on his eyes. He suppressed a cry of surprise before suddenly standing up, looking at his interlocutor. He saw two people. Both were his carbon copy, but one was female and the other was a few inches shorter than him.

"Nii-san! Yuu-chi!"

"Lyosha!"

The siblings hugged each other in infectious laughter, crushing the young woman between the two young men.

"Oh my God!"

The siblings turned around and saw a young Japanese girl, speechless.

"You… are you the Legendary Trio? What are you doing in Fukuoka?"

"We're here to visit our parents!"

Akashi Mikhail Viktorovich Katsuki-Nikiforov and Alexei Jiro Viktorovich Katsuki-Nikiforov were 24-year-old twin Alphas, Akashi being the youngest by a few minutes.

Alexei was the current best Figure Skater of his generation training under Yuri Plisetsky, his uncle in St. Petersburg. He skated for Japan and had won many medals for his country.

Akashi was a Premier Dancer Noble, training in Moscow with the Bolshoi Ballet. Some would say that if Akashi was a woman, he would have had the title of Prima Ballerina Absoluta by his incredible talent linked to the dance and the musicality of his movements.

The twins, although practicing two different disciplines could have excelled in each other's discipline. Indeed, being the children of two illustrious Figure Skaters being trained as hard as iron in ballet, the children learned very early on to imitate their parents, whether on the ice or on stage.

Also, the younger Alpha Yuuki Valeriya Viktorovna Katsuki-Nikiforova, although not being a top athlete was strongly linked to this universe. Indeed, Yuuki had become a sports doctor to support her brothers, not wanting them to be healed by anyone other than her. Despite being only 22 years old, Yuuki was a peerless doctor, rising quickly through the ranks with her talent, perfectionism, precision and speed of execution. (To be completely honest, Yuuki had worked so hard to be the best doctor possible to be with her brothers if they ever got hurt.)

They were called the Legendary Trio, the three sports geniuses.

The siblings lived in Russia. Akashi lived in Moscow while Alexei and Yuuki lived in . Obviously, as the siblings couldn't stay too far from each other, they visited each other once every two weeks and making sure to attend all competitions as far as possible.

But there was that thing that could happen every three months.

Their parents' heat and rut cycle.

It was very rare, but some parents spend their heats and ruts in the company of their children, taking care of them as if they had become small pups again. A week full of being pampered with hugs, food, cuddles and kisses to satisfy their instincts.

Of course, with the Katsuki-Nikiforov family being so close, cycles like those were not uncommon at all. That's why Alexei, Akashi and Yuuki always took a week off to see if their parents would call them.

That was the reason for their coming. Yuuri and Viktor would be spending their cycle as a family, Yuuri unable to resist his maternal instinct to have his pups with him in his nest. Obviously, the siblings being mom and daddy's sons and daughter, they could hardly say no to their mother's call.

So here they are, on their way to Hasetsu.

"When are they going to arrive?" Yuuri Asked.

"Soon my love."

Yuuri inhaled deeply at the pre-rut pheromones Viktor was giving off. The Alpha was lying on the couch, his Omega above him his nose on his scent gland. Yuuri purred softly, comfortable in his mate's arms. "I can't wait to see our children again..."

"Me too Yusha, I have missed them so much…"

A slight click in the door interrupted their discussion. Snow, their White Caucasian Shepherd Dog immediately raised his head and immediately got on his defensive in front of Viktor and Yuuri who stood up.

Akashi opened the door; Alexei was already running towards his parents while Yuuki was laughing out loud.

Yuuri rushed into his oldest son's arms, rubbing his wrist all over to spread his scent everywhere. He did the same with Akashi and Yuuki who began to growl in satisfaction at the smell of their Omega mother. Viktor who was behind did the same, a little less frantically than his mate.

"Tadaima, Okaasan, Papa!" The siblings said at the same time.

"Okaeri pups!"

Even in their 50s, Yuuri and Viktor couldn't be happier than they are now. They had their pups in their arms, happy and bathing in their parents' scents. Yuuri's loud purrs were so calming to the Alphas…

Happy growls of Alphas were heard in the house.

Everyone was happy, and that was the most important thing.
