RikuIo (Ending Fluff AU)

(A/N 1): Here we go again with Bottom!Iori. And there’s a looooooooong cameo from Mitsuki. Loooooooooooooooooooooong. And I’ve made weak omegas and alphas a thing - basically, they’re people who seem like they’d be a different second gender or have weak instincts. For them it’s a bit easier to control their inner alpha/omega.

Iori whimpered, squeezing his eyes shut.

Someone, please! Help!

Riku grinned, walking through the streets. Finally, he thought, Tenn-nii let me walk alone!

His smile faded and was replaced by embarrassment as he scented an omega and an alpha nearby. It was obvious what they were doing. He quickened his pace.

Then Riku caught onto the omega’s scent. It was terrified and panicked - but worse was how obvious that whoever it was was in heat.

Immediately Riku ran, following the scent. His inner alpha was growling. Riku reined him in and realized that the omega was likely getting assaulted. Not only did the idea disgust him, since the omega was in heat they wouldn’t be able to run. They’d get raped and most likely marked, and maybe even unluckily get pregnant.

The thought made Riku run faster.

He found them in a back alley. The alpha was obviously drunk and posed over the omega with hungry, lustful eyes. The omega cowered against the wall, whimpering and clutching a bag to their chest. From this close, the scent almost had Riku stumbling.

Nevertheless, Riku rushed in, swinging his bag at the drunk alpha. “Get away!” He shouted. The alpha staggered back, unconscious. He sighed in relief.

Suddenly Riku became very, very aware of a presence at his side. The omega clung to him and nuzzled his scent glands, whining. “Mate me,” He demanded. Riku stared in growing shock and horror at the quickly dampening spot in front of the omega’s pants. His inner alpha almost took control, but Riku desperately held back. No! He absolutely couldn’t!

After a helpless moment of panic, Riku noticed a ringing from the omega’s dropped bag. He picked it up and desperately fished through it, pulling out the omega’s phone. Someone labelled ‘Nii-san’ was calling, and Riku hoped to hell it was actually the omega’s brother as he picked up.

Instantly a worried voice attacked his ears. “Iori! Iori, thank god, where are-”

Riku cut them off, panicking. “Please, I need help!”

The voice at the other end turned cold, threatening. “Why do you have my brother.”

Riku almost fainted in relief. “Thank god!” He said, “Your brother is in heat and he was assaulted and please-!”

The voice again turned worrying. “Oh god, it wasn’t supposed to start for another two days! Where are you, I’ll pick you both up.”

Riku quickly looked around. “On the ○○○○○ Street and ■■■■■ Street intersection, in the alley next to the ramen shop.”

“Alright, I’ll be there,” The voice said, hanging up. Riku replaced the phone in the omega’s bag quickly and held it and his own, awkwardly trying to keep his inner alpha down and trying to ignore the omega whining and nosing at his scent glands.

After a few stressful minutes, a car pulled up. The small orange-haired driver took one look at them and rushed to open the backseat door. “In, in,” He urged. Riku quickly complied - it was obvious that this was the omega’s brother. He had only managed to seatbelt himself before the omega’s brother stared ahead grimly, knuckles white on the steering wheel, and hit the gas.

When they rushed out a minute later Riku wasn’t sure if he had screamed or not. The omega’s brother left Riku by the door with a quick apology as he bundled the omega away. Riku waited, pale and anxious and both bags in hand.

After a few moments the omega’s brother came back and led Riku to a pair of couches, offering Riku a hot cup of tea and thanking him profusely. “Thank you so much for looking after him,” He said, “I’m sorry you had to see that. I’m Izumi Mitsuki, and my brother’s Izumi Iori.”

Riku laughed nervously, sipping the hot tea and nearly losing the strength in his limbs as he sat down. “You don’t need to apologize, Mitsuki-san,” He said, fidgeting, “I’m Nanase Riku, by the way.”

Mitsuki laughed always sadly. “As I said, Iori’s heat wasn’t supposed to start for another two days. I wonder what happened…”

Riku cleared his throat. “Um, Mitsuki-san, when I found Iori-san he was about to get raped. I knocked out the alpha though.”

Mitsuki paled and looked in the direction of what Riku assumed to be Iori’s room. “Iori…” He murmured, smiling weakly at Riku. “Thank you so much, Riku-kun. I’ll forever be indebted to you,” Mitsuki said, bowing to Riku. RIku frantically shook his head.

“I didn’t do anything, Mitsuki-san!” Riku protested, “I just did what anyone would do!”

Mitsuki smiled and shook his head. “Any other alpha would have lost control and maybe even mated Iori. They probably would have fallen into a rut, and maybe even mated Iori, and at seventeen, Iori’s…” He trailed off.

Riku balked at the idea. Seventeen years old and with children?! He’d never wish such a fate on anyone.

Mitsuki smiled at him. “There aren’t many people like you, Riku-kun,” He said, “You’re special.”

Riku blushed sheepishly. “I’m actually just a really weak alpha.”

Mitsuki shook his head stubbornly. “You’re especially kind, Riku-kun. Treasure that,” He said, softening, “Besides, I can relate. I’m a weak omega.”

Riku nodded. He had noticed that Mitsuki was an omega but it didn’t seem polite to bring it up. But he didn’t know anyone else who wasn’t suited to their second gender. It was nice to know that Mitsuki was like him.

Mitsuki looked at the clock. “Oh, it’s getting really late. I’ll drive you home, Riku-kun.”

Riku didn’t argue and grabbed his bag before following Mitsuki to his car. Luckily he drove more carefully this time, and got Riku home without any mishap. They exchanged numbers and Riku thanked Mitsuki as he got out.

“It’s nothing, Riku-kun,” Mitsuki said, laughing, “I’ll text you when Iori’s heat is over. I’m sure he’ll want to talk to you.”

Riku nodded and smiled, heading inside. “I’m home!” He announced. Immediately Tenn appeared and bombarded him with questions. Riku answered them as vaguely as he could before escaping to his room. He took a shower and brushed his teeth quickly, not realizing how exhausted he was until he collapsed in bed.

Nearly a week and a half later Riku got a text from Mitsuki.

M: Iori’s all better now and says he’d like to talk to you soon! When’s a good time for you?

Riku grinned and started to reply.

(A/N): Is 'ending fluff' a good label for this one? I really don't know...    heh...
