[~*~]

Watching that movie was a mistake.

Except for the part where Teruki got bored with the plot holes - which, together with the roterist's lazy shortcuts to get all the movie's conflicts resolved in less than ten minutes, ignoring completely that they still had 45 minutes left of story to tell, created the perfect setting to enjoy some procrastinating time with a good company - and decided he absolutely needed to stretch himself across Shigeo's lap, looking at him with the corner of his eye to see if he perceived any kind of discomfort with him by the other.

Shigeo's attentive and neutral eyes turned down to watch him back. "Do you want to watch something else?"

The lack of anything but mild curiosity that painted his tune made Teru relax, slightly adjusting himself to be more comfortable and smiling nonchalantly while focusing again at the screaming protagonist on the screen. "Nah. It's fine."

"Ok."

It was calm, the silence that bathed them. Teru felt more than saw the other's hand hovering above his head. Although he didn't allow himself to externally react to it.

"Teruki." He hummed in reply, laziness already beginning to fog his brain and trying to coach him to sleep. He kind of wanted to finish watching the movie with Shigeo, though. "Can I touch your hair?"

"Uh, sure. Go for it."

So, watching that movie was a mistake. Not because it was bad or poorly made. Not because Mob's careful but still very present touch combing his hair made him feel so relaxed and boneless he was afraid he would slip from the couch at any moment. Not even because he realized how... soft this moment was, how soft Shigeo was, even when their first contact, when Teru's first contact with him was much more aggressive and unkind than what he was being shown now.

No, none of these were the reason for the incorrigible mistake that was made that day.

Actually, the moment Teruki realized that something was happening it was already too late to intervene.

Because the scene was already playing on the screen.

Not any scene.

A tickle scene.

And Teru made the mistake of looking up at Shigeo at this exact moment.

His friend was still concentrating on the movie, hand still playing with his hair and... the corner of his mouth was turned upwards. He was smiling.

That was when Teru realized two things:

1. He has never seen Mob laugh or giggle.

2. He really, really needed to be the reason of his smile.

The question slipped before he could think too much about it.

“Are you ticklish, Mob?”

Maybe it was because of his way-too-casual tune, or because the calm moment made Shigeo lower his barriers, but the answer jumped from the tip of Mob’s tongue before he even realized it.

“Yes.”

The blonde could easily notice how, even before the word was completely out, Shigeo realized the trap he was walking into, turning to look at him with alarmed eyes, so Teru didn’t waste too much time. With a predatory grin his fingers jumped to his sides, dancing and scratching from left to right, up and down, effectively searching and finding any and every weak spot where he could latch on and prevent the other from even thinking in payback before he managed to pull at least a single stray giggle.

His worries were, however, unfounded, since the moment the Kageyama’s wide eyes noticed his attack, his entire body tried to curl on itself, arms hugging his torso and legs trying and failing to go up to protect his middle due Teru still being laid on them.

And then, Mob began to shake.

Teru’s fingers faltered, an unpleasant cold fear suddenly appearing on his mind, the fear that he was too rough, too sudden, too close. That he went too far,  overstepped his friend’s boundaries and just made the strongest person he ever known cry for a stupid personal desire.

His eyes then ran to the other’s face, hands still hovering in the air, when he saw it.

Shigeo’s cheeks were puffed out, his eyes were closed, his previous smile now much bigger stretching along his face.

Teru blinked, a bit stunned. The shaking had stopped.

Hm.

He experimentally brought his hands back to his friend’s torso, now skittering along his ribs, index fingers lightly drumming on the space between each one while his thumbs drew circles on the highest ones, the tip of his fingers getting dangerously close to his highest ribs.

Shigeo began shaking again, shoulders jumping up and down just the slightest amount (Teru was sure that if they weren’t that close, he wouldn’t even realize) and small huffs and puffs of air that sounded suspiciously close to muffled yelps made the blonde realize with delight that Shigeo wasn’t just shaking, he was beaming due the amount of giggles and belly laughter he was trying to hide.

That piece of knowledge made his smirk come back at full force, his tickles getting more enthusiastic with this revelation. Now, that just won’t do.

“Come on, Kageyama, you can’t keep them inside forever.” A snort escaped from his tight pressed lips, body swaying a bit to the left when Teruki’s efforts began walking in the direction of his armpits.

Seeing his reaction, the blond decided he wanted to be mean, so he taunted the other by tapping his fingers right on the border of his armpits, just light enough to send tickly tingles where he touched, nerves buzzing with the prospect that he could strike at any moment.

“See? That is already one. You just need to free the rest of them! Let all the high pitched giggles, embarrassing squeaks, cute snorts and melodious laughter come tumbling right out. I promise I won’t break your serious guy façade to everyone we know.”

His teases were accompanied by a couple of pokes to the tickle spot, which made Shigeo duck his head and try to press his mouth on his shoulder, his low, quiet reactions being successfully hidden with it, his bounces getting stronger with the (honestly unfair) mix of silly tickles and taunting teases.

Suddenly, Teru had an idea. It was a risky bet, more than anything. But it could work.

He kept the flow of pokes, slowly increasing the speed bit by bit. “Bet you will feel much better once they’re all out,” Poke. Poke. Poke poke. Poe poke poke.  “don’t you think? To just let it go and laugh and laugh and laugh.” Pokepokepokepokepokepoke.

Mob didn’t answer, the sensation and words making him want to both crawl off his skin (Teru wasn’t even full tickling him yet, how such soft touch could be so maddening-) and not laugh so they could extend that playful moment for longer.

Teru let out his best impression of an evil snicker, lifting himself just a bit more and...

His mouth was now close to Shigeo’s ears.

Perfect.

“Unless you want me to tickle it all out of you.”

As soon as the words filled the room, his hands dug on the armpits, vibrating and unmercifully attacking the so-protected tickle spot with plenty of scratches and scribbles while he blowed weakly at the - now completely red - ears, hoping his assumption that they were ticklish was right and he wasn’t just making a fool of himself.

A surprised and surprisingly loud, high pitched wheeze was his answer and, before the silence could stretch across the room, a waterfall of sounds followed it. Snorts, yelps, squeaks, squeals, titters and an adorably adorable hiccuped laughter began flowing freely from the one with raven hair and they filled every inch of the room, stunning the blonde so much that he almost ceased his attack.

Instead, he pried his hands from under Mob’s arms and shot them upwards, targeting the, as it seems, incredibly and awfully sensitive spot right behind Shigeo’s ears, letting them dance and draw senseless forms on them, skittering the shells and sometimes letting the tickles slip a bit too close to his neck. 

A pure and warm delight exploded on his chest when he watched how such a simple thing made Mob throw his head backwards, not even bothering to try to hide the low and fast giggles that spilled in flocks from him, shoulders still bouncing and trying - even if halfheartedly - to press on his ears and save them from the unfair and unexpected attack.

“So your ears really are ticklish.” It wasn’t even a tease now, Teru was so lost in the realization that this was laughter, this was his serious friend, this was the strongest person in the universe laughing and enjoying himself, this was his attentive friend giggling uncontrollably and non stop because of a few silly tickly tickles, that he even forgot to add that snarky, taunting tune in his words, just letting the fun of the moment carry both of them away.

“Yes.” The word was almost unrecognizable when said in between so many titters. Teru’s hands began to explore his neck, tap-tap-tapping non stop from the spot right under his chin to his shoulders, creating tickly, tingly paths wherever he went and Mob knew that the spot wasn’t even that ticklish in the first place, but in this moment it didn’t fail to fish plenty of squeaky yelps from him. His hands shot to hold the sleeves of Teru’s shirt, not really pulling them away. “Teheheru. It t-tihihickles.”

And that was the exact moment Teruki Hanazawa realized he had made an incorrigible mistake.

Because now he wouldn’t ever, ever be able to live without listening at least once again to his name being said in between those bouncy giggles and huffed titters.

Or without seeing that gigantic smile taking over Shigeo’s face. Or the way his cheeks were still puffed out even though the laughter kept falling and filling the air. Or the way the tip of his ears were starting to be painted in a lovely shade of red. Or how low and silly his laughter was. Or how...

Oh.

Oh.

Teru was the one who walked straight to a trap here, wasn’t he?

He felt his grin turning into something much more soft than playful, and tried to pull his smirk again, not being sure if he was successful or not. Fortunately enough, Mob still didn’t open his eyes or he would, without doubt, see the shine that took over his gaze.

“It is supposed to tickle, Kageyama. This is the whole deal here, you know?” He snickered in amusement, lowering his arms to give the boy’s knees a few experimental squeezes, being gifted with a snort at every single one. “But, I must say, I didn’t think you would be so, so ticklish. Maybe we should change your nickname from Mob to Giggle Storm.” Teru wormed one hand to under his knees, slightly pinching the sensitive skin there while the other one kept squeezing the kneecap, the mix of soft and rough tickles creating a stronger hiccuped laughter and low, high pitched giggles, as if to prove his words. “Or maybe Hiccup King, it would be very fitting, right?”

Mob only shook his head, heat flooding across his entire face, body starting to get too tired to keep his beaming and tears beginning to gather in the corner of his eyes. A couple of squeaks escaped from his lips and he tried, once again, to curl his torso, resting his forehead on Hanazawa, who was still on his legs.

A privileged position that the blonde didn’t even think twice before fully exploiting. Shigeo could only get a glimpse of Teru taking a deep breath before shoving his face on his stomach and giving him a huge raspberry.

Another loud, wheezing sound briefly floated in the air before being cut and replaced by full silent belly laughter, one or two hiccups appearing here and there before the one with raven hair fell again in silence.

When the maddening, tickly vibrations were over - even if the buzzing kept dancing across his torso and making the other spots tickle in empathy - Mob put his hands on the other’s shoulders and pushed it away, his arms feeling more wobbly and noodly than normal, as if he had just went through another exercise from the Body Improvement Club. Teru took a look at the few tears running on his cheeks and the gigantic smile on his lips before chuckling and ceasing his attack.

For a moment, they just stayed like that. Shigeo taking deep breaths and slowly stopping the flow of quiet titters that remained dancing around them. Teruki realized that the movie had ended a long time ago.

"Uh, sorry if I went too far. Just... It really looked like you were having fun." The playful tease left his grin before he even realized it.

"I was." The certitude in his tune, the direct way he didn't even seem phased by the whole tickle attack and tease he just received beyond a light redness taking over his cheeks and a smile still adorning his face... Mob was really something else.

In his place, Teru would probably still be a mess of peals of laughter and pleas of mercy. Actually, cross that, his soul would have flown away from his body the moment he received that raspberry.

"I don't mind being tickled. It's fun."

"Heh." Teru's smile got even bigger, losing somewhat its smirk, sincerity dripping freely in his tune. "That is cute."

Mob considered his words, not saying anything to agree or disagree to it.

A comfortable silence fell on them once more.

"I also don't mind getting revenge."

"Ah- wAIT-"
