Characters: Lee!Geto, Ler!Nanami, Ler!Haibara, Shoko, Yaga, Gojo, Yuji Summary: Someone (definitely not a white haired imp) spikes Suguru’s morning tea with the essence of a curse as a prank. Problem? That curse is a tickle hungry curse. He’s in the worst lee mood of his fucking life now, bestie. *Tickle AU* Word Count: 3880 Tickletober 2025 Masterlist
“Gojo? What are you doing?”
The sound of Yuji's voice behind Gojo startled him, he quickly turned around with a grin, obscuring a bottle behind his back.
“Me? Nothing!”
Yuji raised an eyebrow at him. “Uh huh… I just watched you put something in Geto sensei's tea.”
Satoru sighed dramatically, quietly dropping the vial into the trash behind him as he did. “Okay, you caught me… I was adding some extra honey to his tea. Every morning he adds too little and he's grumpy for hours, so I sneak in while he's not here and add extra to make sure crabby Suguru consumes enough sugar in the morning.”
The pinkette just stared at him in confusion. That was absurd… but also so on brand for Gojo. “Why don't you just tell him he needs to add more honey to his tea?”
“Oh, poor sweet boy… Come, let me lament to you the horrors of being married.” Satoru threw his arm around Yuji's shoulders and began leading him out of the room. “You never tell your wife they're wrong…”
“Okay… two things, one, you're not married… and two, if you were, you would be the wife.” Yuji retorted as the two walked away from the classroom.
Moments later, Geto returned to his classroom with his breakfast bento box.
He sat down at his desk, humming softly as he took a bite of his food.
His purple eyes roamed across the papers he was grading. He always opted to come in early in the morning to eat his breakfast and drink his morning tea, and work on whatever he left for the next day from the day before.
He stirred his tea idly, his eyes not leaving the page as he brought the cup to his lips and took a sip.
He made a face, looking down at the tea. ‘Why does it taste strangely sweet?’
He sighed heavily. Satoru must've snuck in and spiked his tea with extra sugar he insisted he needed to function.
‘Whatever… I'll just have to start taking it with me.’
Time passed, and eventually Suguru finished his cup of tea and breakfast.
As he focused on his work, he began to feel… odd.
The window was open, and a soft breeze was coming in, blowing his hair gently. He became acutely aware of every hair brushing against his neck.
He grumbled, and gathered his hair in his hands and tied it up into a bun.
But that didn't help, because even the breeze brushing over his skin was causing him to flinch.
He stood up and closed his window, then returned to his work.
He found that he couldn't focus, he felt restless suddenly… like he was having some kind of caffeine high.
‘What did that idiot put in my tea?’ he huffed, he rolled over to the trash can and found the vial in the top of it.
He plucked it from the bin and studied it curiously. It was unlabeled… rather, it had a label but it had been crudely removed.
‘Satoru…’
Suguru stood up and marched out of his classroom towards Satoru's.
Gojo was at his desk working on a mission report while sipping his morning juice, when he sensed Suguru coming he put on the most innocent smile he could.
“Suguru, how can I help y–”
“Don't give me that shit…” Suguru closed the door behind him, holding up the vial. “What did you put in my drink?”
Satoru gasped dramatically. “I'm wounded! You think I would do such a thing??”
Suguru huffed and got closer, setting the vial down on his desk. “Shut up, what did you do to me?”
Gojo reached over and prodded his side. “I have no idea what you're talking about… I just sweetened your tea!”
Geto gasped sharply and recoiled, something that would usually just make him internally flinch made him recoil… Why was he so sensitive?
Gojo blinked, then grinned. “You alright?”
“Satoru, if you don't tell me what you put in my tea…”
Satoru put his hands up defensively, sensing Suguru was becoming distressed. “Alright alright, take it easy… it's harmless, I put some cursed essence that Shoko extracted from that curse Yaga dealt with last week in your tea.”
“Curse… essence?” Suguru thought about it for a moment, then paled. “You didn't…”
Satoru grinned and jumped up before Suguru could snatch him up. “Heheheh! Well, she needed a guinea pig to see what effect it would have, so I volunteered you!”
He jumped out of reach again, cackling like the gremlin he is. “Don't worry, I didn't put enough in to make it last too long… Shoko's calculation was that it would last four hours.”
“Four fucking hours?! Satoru Gojo!” Suguru hissed, lunging for him again only to miss.
“Have fun with your tickle curse essence~ I have a mission!” Satoru bolted before Suguru could snag him, he went stumbling out into the hall after him but Satoru was already almost to the stairs.
“You bastard! This isn't over!!” Suguru yelled after him, only to get his gremlin laugh in response.
Four hours of hyper sensitivity? Goddammit… Well, Suguru could always go and nap it off…
He groaned and rubbed his temples, then headed back to his living quarters on the teachers wing.
He flopped down on his bed and threw an arm over his eyes, trying to will himself to sleep.
But something happened… The essence progressed further. Now he was getting intrusive thoughts, thoughts of being tickled senseless.
He kept trying to push the thoughts away, but they kept coming back, becoming more intense with each passing second.
Then memories of him being teased and tickled by his friends came back into his mind.
He groaned.
He's in a lee mood.
He hasn't had a lee mood in ages… it had to be the effects of the curse.
“Goddammit, Satoru is a Deadman. The least that bastard could've done is stayed and tickled me.” He huffed grumpily.
There was no way he was gonna get a wink of sleep like this… he needed to go find someone to satisfy his lee mood.
But who…? Satoru was the obvious first choice, but the goose gremlin took off.
Shoko? No way, she wouldn't humor him. She'd tell him to deal with it.
Nanami? He's so uptight… he doubted he would help him.
Maybe Haibara would tickle him… if he wasn't out on a mission himself.
Geto sighed and trudged defeatedly to Haibara and Nanami's classroom, to see if the golden retriever was around.
Alas…
“Suguru?” Nanami glanced up from his laptop where he had been working. “Did you need something?”
Suguru sighed, feeling his cheeks burn. “Is Yuu around?”
“No, he stepped out for a bit…” Nanami took his glasses off and ran a hand through his hair. “Is there something I can help you with?”
This was about the most humiliating thing Suguru has ever gone through… but he has no choice.
“So… Satoru spiked my morning tea with a cursed spirit's essence…” Suguru began, his eyes locked on the floor as he fidgeted with his sleeves.
“Sounds like something stupid he'd do.” Nanami mumbled, resting his elbows on his desk and propping his chin up with his hands. “Are you feeling alright?”
“No…” Suguru sighed, flopping down into the chair across from Nanami, burying his face in his hands to hide his embarrassment. “The essence he slipped into my drink was some of the essence that Yaga collected from that one tickle curse he encountered last week.”
Nanami raised an eyebrow, slowly lifting his head. “Is it making you sick?” He asked, a touch of unusual concern in his voice.
The blond always had a softer spot for Suguru, if this was Satoru sitting across from him, he'd still be working on his laptop half listening to him.
“N-No… at least I don't think so… it's just… making me really sensitive.” Suguru explained.
“Ah… interesting. So its essence can act as a sensitizing neurotoxin, like the ones some of those curses can use.” Kento mused, his tone thoughtful as he considered it.
“There's… also another side effect…” Geto frowned behind his hands. “It… it's filling my head with nothing but tickling. I needed Haibara because I was going to ask him to tickle me… and pray that it helped.”
The blond blinked as he processed that. “So… you're in a lee mood?” He asked blankly, making Suguru grumble.
“Yes… the worst one of my life…” The ravenette removed his hands from his red face, letting out a breath. “But since Haibara is gone… I guess that won't work.”
“Why not ask Gojo? Aren't you both normally attached at the hip?” He asked.
“Oh, that's the best part. The bastard left for a mission. Abandoning me for the duration of the damn thing.” Suguru huffed.
“Wow, that's low, even for him.” Nanami frowned. Oh, he was definitely gonna help Suguru get revenge later.
“Yeah…” Suguru rubbed the bridge of his nose. “Well… I guess I'll just go figure something else out… maybe Yaga is available.”
“Ah, hold on a moment.” Nanami stopped him. “Yaga is in a meeting with the higher ups… he's not going to be available for two hours.”
Suguru groaned. “Of fucking course he is…”
Nanami was quiet for a moment, then spoke. “Um… I can… help you, if you want.”
Geto looked at the blond man in disbelief. “You… are you offering to tickle me…?”
“Y-Yeah…” Nanami glanced away awkwardly. “I'm sure it's miserable what you're going through… and Gojo's stupid ass didn't even have the decency to stick around to watch over you.”
“Oh trust me… his ass is grass when he gets back here.” Suguru mumbled.
“So… Do you want me to help you…?”
Suguru paused, nervous all of a sudden at the potential of getting tickled soon. “Um… i-if you don't mind…”
Nanami nodded and stood up, walking around the desk. Suguru started to feel butterflies, and his pride was begging him to get away, but literally every other cell in his body was begging for the tickles…
The two sat down on the floor so it would be easier.
“Alright, just… let me know if you want me to stop.” Nanami said quietly, his hands reaching forward.
Suguru's eyes locked onto them, and he already began giggling in anticipation when they neared his sides.
Kento paused, a smirk forming on his face. “I'm not even touching you yet.”
“Sh-Shut up.” Suguru blushed, covering his face.
Nanami chuckled, feeling a small sense of satisfaction, usually it was him in Suguru's place all flustered and indignant. It felt good to not be on the receiving end for once.
He moved his hands forward, his movements careful and gentle as he began to spider his fingers along Suguru's sides, methodically probing around to find sensitive spots.
The problem is that every spot is sensitive to Suguru right now.
The older man squealed quietly and erupted into a fit of giggles, keeping his face obscured by his hands.
The blond smirked. He hated teasing, he always got horrible backsplash damage from it… but he decided to do it anyway, because he couldn't resist the opportunity to get some revenge from over the years. “Why are you hiding your face from me?”
Suguru whined, squirming around as his fingers found a mean spot on his lower sides near his hips. “Dohohohont tehehehease!”
“Oh, I'm definitely gonna tease. Consider this karma for our students days when you would always torture me.” Kento chuckled, grabbing ahold of his hips and massaging his thumbs in those oh so ticklish dips.
Suguru yelped and threw his head back laughing, his hands shot down to grab at Nanami's hands, but he did nothing to try to remove them.
“Nahahahahaha! Ahahahahahah!”
A rare playful grin formed on Nanami's face as he caught sight of how red and flustered Suguru was.
This power was a little intoxicating… No wonder Gojo and Geto always wreck people and tease them into oblivion.
“Sorry, I couldn’t quite hear you… are you trying to tell me ‘no’?” Nanami stilled his hands. “Does that mean you want me to stop?”
Oh… this bastard.
“N… No… That’s not what I… was trying to say.” Suguru panted softly, turning even redder.
“Oh, then what were you trying to say?” The blond asked innocently, watching him intently. This tired blond bitch was gonna get it when he was in his next ler mood.
“I was… t-trying to say your name…” Hmm… sure, he totally wasn’t trying to say no. Not at all. He didn’t actually want him to stop anyway, It was just an automatic reaction from him to try to get away.
“My name, hm? Were you trying to get my attention? Was there something you needed?”
“Kento…” Suguru growled, narrowing his purple eyes dangerously at the blond. “Knock it off.”
“Knock what off?”
“You know damn well what you’re doing… Gojo used to do it to you all the time.”
Nanami smiled innocently. “If… hypothetically I was doing something that had been done to me in the past… you also did it to me several times.”
Suguru scowled. Curse him and his excellent memory.
“Fine… you win.” The ravenette sighed, averting his eyes to stare up at the ceiling.
“Oh? What do I win?”
“Tickle me.” He muttered quietly.
“Sorry, I didn’t quite catch that~”
“I said I want you to tickle me, goddammit! Are you happy now??” Suguru huffed, his cheeks burning.
“Very.”
Before Suguru could grumble any further complaints, he began kneading his thighs, causing him to squeal and erupt into a fit of higher pitched laughter. “Ohohohoho god! Ahahahahahaha!”
Now he has to be mindful not to say ‘stop’ ‘dont’ or ‘no’... rip Geto’s pride and ego. There it is… broken and all over the floor. Watch your steps everyone.
“Is that better?” Nanami teased, alternating between squeezing his hips and squeezing his thighs, keeping the ravenette in a constant stream of laughter.
“Yehehehehes… nohohohow stop teasing mehehehehe!” He whined between laughs.
“Sorry, It’s too much fun. You’ll live.” He chuckled, his fingers suddenly darting under his arms and attacking the sensitive flesh there.
Suguru gasped sharply and threw his head back cackling, hugging his arms to his sides as he did. “SHIHIHIHIT! AHAHAHAHAHAHA!”
Nanami clicked his tongue, still tickling him but definitely slowing down. “Suguru, I’m gonna need you to lift your arms. It’s kind of hard to tickle you when your arms are wrapped around you like a vice.” He half teased, smirking when Geto blushed.
Oh god… the thought of being forced to stay still and keep his arms above his head while Nanami tickles him is so freaking flustering… He doesn’t think he could do it to save his life-
He shakily lifted his arms over his head, locking his hands around his wrists tightly to keep himself from pulling his arms down.
“That’s better. Stay still~” He hummed, spidering his fingers gently across his underarms. This caused the usually composed, calm and collected man to squeal and wriggle around as he laughed.
“THIHIHIHIS IS MEHEHEHEAN! I HAHAHAVEN’T TICKLED YOU IN AHAHAHGES!” He whined between his fits of laughter, protesting the (arguably well deserved) revenge he was enacting.
“Oh, this isn’t mean.” Nanami chuckled quietly. Oh god… he didn’t like that sound. “This is mean.”
His eyes flashed green, and Geto’s face flashed red as a scream tore from his throat. Nanami used ratio to make his underarms more sensitive.
The ravenette flailed as if electrocuted, his back arching sharply as he shrieked with laughter, but never once brought his arms fully down.
“YOUHUHUHU’RE RIHIHIHIHIGHT! BAHAHAHAHAHA! THAHAHAT’S SO MEHEHEHEHEAN!” Suguru cackled, his eyes tearing up.
“Nanami! I heard a scream is everything…” Haibara paused in the doorway, tilting his head curiously at the sight before him. “Uhh… What did I miss?”
Oh, so now Haibara is here. But not earlier before the blond decided to torture him???
“Oh, Hey Yuu.” Nanami greeted his best friend casually, as though he wasn’t absolutely wrecking Suguru right now. “Gojo slipped tickle curse essence into his tea… and It put him in a really bad lee mood. He came looking for you but you had just stepped out, so I told him I would help.”
Haibara blinked, just processing the scene for a moment. “Oh…” He walked in and set the bag on his desk and turned back to them with a playful grin. “Can I help?”
‘NO! Absolutely not!’
“Sure, come here.” Nanami paused his tickling and let ratio fade as the cinnamon roll joined them on the floor.
“Hehehe, you’re all red and teary, Suguru~” Yuu cooed, reaching up and gently wiping the tears away from his eyes. “Are you alright? Do you wanna keep going?”
Poor Geto and his ego…
He nodded reluctantly as he panted and trembled.
“Alright~ Then here it comes~” Haibara slowly inched his hands closer to Suguru, fingers wiggling as they neared him.
Geto began to giggle anxiously as he watched his fingers, squirming as he did. “W-Wait, hold on…”
Haibara, having had plenty of experience with tsundere lees… (cough nanami cough) knew exactly how to deal with Geto in his current state… by teasing the ever loving snot out of him.
“Nope, no holding on~” He cooed, his fingers spidering along the ravenette’s stomach. “Just relax and let the giggles overtake you~”
Suguru gasped sharply and nearly doubled over, he went to bring his arms down, but Nanami caught his wrists and held them firmly above his head. “Nope. Stay still.”
“EHEHEHEHEHE! H-HAIBAHAHAHARA NOT THEHEHERE!” Geto whined between laughs and loud giggles.
“Awww, does this tickle~?” The brunette teased, his fingers slipping under his teachers jacket and undershirts to spider along his bare toned tummy. “Tickle tickle tickle~”
Geto was in ticklish hell right now… and his body wouldn’t allow him to get away. It still craved the tickles. “AHAHAHAHAHAHAHAHAH!! STAHAHAHAHAP!”
“Nope~ I’m gonna keep tickling~ and tickling~ and tickling~” Haibara kept his touch feather light as he scribbled his fingers along his lower stomach, causing Suguru to snort. “Until you’re a giggly, content little heap on the floor.”
This continued for a bit, then Haibara had an idea. “Kento, could you lay him down for me~?”
Nanami nodded, carefully repositioning Suguru to lay on his back on the floor. “Like this?”
“Yup, just like that.” Haibara grinned, unzipping Suguru’s jacket and letting it fall open, then pushing his dress shirt and compression shirt up. “Awww, look at that cute wittle tummy~” He cooed, slowly leaning down closer. “It’s just begging for some raspberries~”
“No… N-No, you wouldn’t!” Geto squeaked, trying to squirm away from Haibara, but the cinnamon roll just grabbed his hips and held him down.
“Oh, I definitely would.” Yuu winked at him. “Just ask Kento~”
Nanami huffed, his cheeks turning pink as he looked away. “... He would.” he mumbled, his tone resigned.
Haibara leaned down without further comment and blew a raspberry against Suguru’s squirming stomach, making him scream and explode into a fit of loud laughter, especially when he repeated it a few times.
“NAHAHAHAHAHAHAHAHAHA! AHAHAHAHAHA!” The ravenette writhed under the two’s grasp, tears of mirth crinkling in the corners of his eyes.
This went on for a while until Haibara eventually had mercy and stopped tickling.
“What in god's name is going on?” Shoko mumbled as she and Yaga stood in the doorway, both having just returned from their meeting.
Haibara giggled as he went to the electric kettle to heat up water for some tea for Suguru as Nanami helped him sit up. “Satoru spiked his tea with that essence you were working on.” Nanami explained.
“Essence?” Yaga parroted, confused.
“Oh, you mean the neurotoxin?” Shoko asked for clarification.
“Neurotoxin!? That bastard spiked me with the neurotoxin!?” Suguru gasped, still heavily breathing to catch his breath.
“Yes and no.” Shoko hummed, leaning against the door frame. “It was the neurotoxin before I altered it. I separated out any impure qualities that might’ve made it dangerous.”
“How’d you get your hands on the neurotoxin anyway? I thought we didn’t have any samples in the…” Suguru paused, thinking back to what Satoru said. “Wait…”
He looked over at Yaga. “You… You got infected with the neurotoxin, and Shoko took your blood to get the sample.”
“Unfortunately, yes.” Yaga sighed in resignation.
“I separated the neurotoxin from his blood, then removed any harmful qualities the dose held.” Shoko clarified. “I ended up with a decent amount of it, I’m just trying to work out how it all works so I can reverse engineer it into an antidote.”
The three nodded in understanding, and Haibara returned to Suguru with a cup of tea with lemon and honey for his voice. “Here, this one doesn’t have any neurotoxin in it.” He teased good naturedly, handing the cup to him.
“So… If Yaga was originally dosed, that means he would’ve experienced the same side effects I did, right?” Geto asked after taking a sip of his tea.
“Well technically–”
“Nope.” The principal quickly denied. “I didn’t have any side effects.”
Geto narrowed his eyes suspiciously at his former teacher. “I find that hard to believe…” He looked at Shoko, who shrugged.
“Don’t look at me, he’s the one who lived through it. He seemed fine when I drew his blood.”
“How potent was the initial sample?” Suguru asked casually, sipping his tea.
“Pretty damn potent. He was mega dosed with it.” She answered. “I ended up with four vials of the essence from two vials of blood.”
Suguru looked back at Yaga. “There’s no way you didn’t have any side effects… I was just going to ask what you did to get through them.”
“Nothing,” He shrugged. “I didn’t have any side effects.”
“But… sensei, if you didn’t have any side effects… then how did you know the neurotoxin would still be in your blood when you got to Shoko?” Haibara asked, tilting his head curiously.
Yaga tensed.
Well fuck.
“Oh, would you look at the time? I have another meeting starting in ten minutes–”
Before Geto could try to stop him he was gone, Shoko giggled and shook her head fondly. “He totally had side effects. He was jumpy when I drew his blood.” She elaborated. “I asked him later how he made it through the effects… he said he meditated deeply and just stayed locked in his room until it wore off.”
“I don’t know how he did it… I tried to sleep it off and it felt like torture.” Suguru sighed.
“Oh yeah, speaking of… you should come to my office so I can talk to you about what you experienced, so I can get a better understanding of how it works.”
Geto paused, narrowing his eyes at Shoko. “Speaking of, indeed… why on earth would you give Satoru a dose of the essence in the first place?!”
Shoko shrugged. “I was bored.” She answered honestly, causing them all to just stare at her. “Besides, it was either give him a controlled dose, or have him snatch a larger dose to satiate his curiosity… I went with the former.”
The ravenette sighed deeply, pinching the bridge of his nose.
“Satoru Gojo… you better watch your back.”
