Leaning forward against the wall, Kyouya secured his prey. His eyes burned with hunger, like a carnivorous predator eyeing on a herbivore. He leaned forward to get a taste of his meal. But instead of being scared like he usually is, the herbivore simply smirked and - POOF!

Smoke surrounded the prey and a smaller silhouette appeared. Kyouya, with his very fast reflexes, took out his tonfa and sent the shadow flying.

"Hiiiiiiii!"

He knew that his prey was replaced by his 10-year younger self. What irritates him is the timing. Of all the time, why now? Just when he was about to savor a delicious meal.

The smoke eventually faded and the middle schooler Tsuna, leaning on the floor and holding his swollen left cheek, appeared.

"H-Hibari-san!"

"Shut up, herbivore. I'm not in a good mood right now," Kyouya crouched in front of him. "I'll definitely bite you to death!"

"Hiiiiiiii!"

...

POOF!

Smoke clouded Tsuna's vision. When it lessened, he found himself in his small room from 10 years ago. 'Seems nostalgic,' he told himself with a soft smile.

"Ciaossu, Tsuna," a familiar voice greeted, "You've grown."

"Ah! Reborn!" he exclaimed with eyes full of happiness. The baby was on the table in front of him. "We're you tutoring me?" he asked upon seeing notebooks in front of him.

"Yes. And you haven't finished your homework." Reborn reached for a snack on the table. "And being here, it is your responsibility to finish it."

"Eh? Can I pass on this one? Please, Reborn…" the brunette clasped his hands and kneeled to plead.

The baby's lips curled up a little and agreed. "As a reward."

...

"H-Hibari-san…" Tsuna couldn't move an inch from his position. He's scared of the person with him. "W-Why am I blindfolded and handcuffed?" he hesitatingly asked.

"I told you to shut up, didn't I?"

"Hiiiiiiii!"

Kyouya's hands crawled under his shirt and made their way to his chest.

"And I told you that I'll bite you to death."

Something soft and wet touched Tsuna's left ear. It sent him shivers and also made him gasp. The other's free hand started stroking his buttons.

"Hi…Hibari…san…" But he couldn't resist; his hands were bound.

Pinching. Nibbling. Licking. Nipples. Ear. Neck.

His cheeks turned rosy pink and sweat formed like beads on his face out of embarrassment. Kyouya lifted Tsuna's shirt, exposing his back, and gently kissed his back. But the herbivore still can't keep quiet.

"Hiiiii!"

Irritated, the carnivorous predator bit his sides, leaving bite marks on his skin, and licked him softly. Still feeling the pain, the poor herbivore felt no sooner the other's grip down below. Just as it was grinded and squeezed, he realized and turned beet red.

"So you like this, hm?" Kyouya whispered, teasing.

"Hn…!"

"You're getting bigger. Should we take it out?"

"Hi-Hiba-"

...

HUFF. HUFF.

'I'm really worried about what Kyouya will do to the younger me…' Tsuna thought as he wan towards a very familiar place. 'How will he bite me to death?' Terrible things flashed through his imagination. 'Hiiiiii! The younger me will definitely be full of bruises when he gets back!'

"Oi, Tsuna!" a known voice called out.

He stopped from his tracks and spotted a familiar figure approach from the school's baseball field. "Yamamoto," he smiled.

"Classes are already over. Why do you seem to be in a hurry?"

"Have you seen Kyo-Hibari-san?"

"He might still be in their office."

"Thanks!" he waved good bye. But before completely leaving, Tsuna told his friend, "You're looking good, as usual!"

'Hm?' Takeshi thought that something's wrong with Tsuna but easily brushed off the idea.

The brunette went in their building and tried to remember where the reception room is. Just as he passed by the lavatory, he bumped into another familiar face.

"Tenth!" A silver haired guy as tall as him greeted energetically. "I thought you went home already?"

"Gokudera! Just in time."

"You suddenly grew taller, Tenth. Just this morning you were this tall…" He raised his hand just below his eyes.

'I can't tell him that I came from the future…' Tsuna thought nervously. "M-Maybe you're just imagining. A-Anyway, I'm on my way to the reception room…"

"Reception room? Then I'll accompany you there!"

"A-No need, Gokudera…kun. I can-"

"No worries, Tenth! It's the job of the right hand man to accompany the boss."

Tsuna couldn't think of any excuses. He want to go alone to his Kyouya. "But…Hibari-san doesn't like crowds…"

Gokudera suddenly froze. "That bastard!"

"I'll be going then."

...

'I don't want to hurry this up but…'

"…only a few minutes left…right?"

"Hm?"

Tsuna couldn't pick up what the other said. His head was hazy and confused. Kyouya's hand slipped in his pants and felt his backdoor.

"H-Hiiiii! Hibari-san! Such thing-!"

"You can't be the only one enjoying."

"You need some stretching."

"Hn."

Breathe.

They were pulled out. But not long after, something bigger pushed in.

AAAAAAAAAAAAAHHHHHHHHH!

Tears ran down Tsuna's eyes. He haven't experienced something like this before. It definitely hurts…but somehow…

"P-Please…H-Hibari…san…I…"

A hand unexpectedly held his handcuffed hands.

"…just a little…longer…"

Slow rhythm. Moderate. Fast.

"Hibari-san!"

"Hnn…!"

...

'I want to see Kyouya's younger self, too.'

Tsuna was standing in front of the Disciplinary Committee Office. He was excited and could not contain the smile he's wearing. It was quiet. He knocked three times and stated his presence but no one answered. Just as he opened the door, he heard a loud crash. He finally saw the person he was looking for! On the floor, under his sworn brother, Dino.

"Y-Yo, Tsuna!"

"Get off me, pervert." Kyouya took out his tonfa and sent the blonde flying. "What do you want, herbivore?"

The poor herbivore couldn't move. He was still shocked with what he saw. Even though it was very abrupt, he saw it. They're not just over each other. Their lips…

"I don't have any obligation to explain to you what you saw." Kyouya stood up. "If you don't need something, scram. Or I'll-"

The smile he wore before entering was still there but a weaker one. He tried to suppress it but tears began to flow from his eyes. 'It hurts…' He bowed his head and clenched his aching chest.

'It hurts…'

The abrupt moment he saw kept looping in his head: their lips locked in each other's. Tsuna looked up, still with tears on his eyes, at the man before him. For the last minute, he gazed at Kyouya's usual frowned face. And smiled.

POOF!

A/N: Ciaossu! I haven't written something for more than a year! D: I had problems with my writing style. Now I'm a little confident. Haha. I came back with another BL fanfic but with a different pairing. I think I made them a little OC's. Sorry. Just have to remove this from my mind and my chest! Haha. Hope you enjoyed reading. I'm planning to write another chapter in continuation to this. But, who knows, I might not be able to come up with something good. Lol.
