This for Guest who requested the idea. Personally, I can't imagine anyone besting Thranduil in a tickle fight, but...I'd say he has had the upper hand long enough, without retaliation that is. Time for a little centuries' worth of suffering for our stiff Elven king! And in the movies, he just never laughs. Everyone needs a laugh sometimes, especially him!

Let's get him! It's time for stubborn Thranduil to learn a lesson! Who's with me? Ready? Attack!

Thranduil is one expert tickler, having to raise two children on his own. But he considers himself much too dignified and immune to such silliness. One day, his daughter accidentally makes him squeak, discovering that he is indeed ticklish. Having been his tickle victim hundreds of times over the centuries, she tries her hand at revenge. Legolas walks in and gleefully joins her, attacking his dad.

Both elflings think they have finally gained some leverage on their stern father. Their victory is short-lived. Enjoy!

I don't own LOTR.

Legolas had returned from patrol a couple hours ago. Alasse, his sister, had had her lessons on diplomacy with the palace tutor and was now enjoying some free time to enjoy reading her book while she waited to join Legolas at the training fields. While Thranduil permitted her to learn the use of arms, he refused to allow her out on patrols and hunting parties. That was Legolas's job.

Thranduil entered her room without knocking. "Ada? Is everything alright? We were not expecting to see you until we retired tonight." Alasse said in surprise. More dangers had been entering the forest, and Thranduil's children saw less of him than they used to. Granted, they were older now, and could understand that. But he still missed them.

"That is just it." Thranduil sighed as he came to the bed. "I have a strong notion that I shall be swarmed tonight. So, I wanted to catch at least a few moments' peace with my daughter."

"Aww." Alasse gushed.

"What are you doing? Isn't about time for your sparring lessons with Legolas?"

"Not for another forty-five minutes. Thought I would steal away where I left off before I need to go." Alasse said.

"I see." Thranduil nodded. He peered sharply at the volume. "Again? Haven't you read that one at least a thousand times?"

"Two thousand, for those of us who are counting." Alasse corrected him, snickering. "It never gets old."

Thranduil shook his head. When did he ever get time to read, just for leisure? "So..." He began slowly.

"So? What?"

"Any certain young ellyn catching your eyes without my knowledge?" Thranduil teased.

"No, of course not, Ada." Alasse shook her head. That was ridiculous! And so, random. It wasn't that she didn't want to be married someday. She did! But so far, no one had captured her interest. And besides, she had a difficult time letting herself consider a relationship since her ordeal with Prince Durion.

"No?" Thranduil grinned incredulously.

"No." Alasse groaned.

"Well, if that is your version of the facts, my sweet, you just stick to it." Thranduil said cockily.

"Ada!" Alasse glared at him. Unexpectedly, Legolas poked his head in the room.

"Legolas." Alasse spoke.

"I shall be ready for our lesson in fifteen minutes." Legolas told her. "Oh, hello, Ada."

"Legolas." Thranduil nodded.

"Already?" Alasse furrowed her brows.

"Mmm-hmm!" Legolas replied quickly and shifted down the hall. Alasse made a face and plopped her book on the bed.

"I wasn't quite ready." She huffed.

"You'd best get ready." Thranduil said. Well, that was a short visit!

"I suppose so. But thanks for coming to see me." Alasse smiled. She started to shift off the bed. "Well, I guess..." Her elbow nudged Thranduil's lower side as she swung her legs over the edge of the bed and he suddenly jolted, surprising even himself. "Ada?"

"What?"

"What was that?"

"Nothing." Thranduil said firmly.

"But, you...you twitched." Alasse pointed out.

"I did not twitch." Thranduil held his head high.

"But you did." Alasse frowned.

"I did nothing of the sort. Now, go and change. You'll be late for your lesson." Thranduil grumbled.

"Ada?" Alasse cocked her head, coming back to him. "What's with you?"

"Nothing. Now scram." Thranduil threw her his infamous glare.

"Okay." Alasse said timidly, but she 'accidentally' brushed her hand across his side again and her father let out a small, surprised gasp. "That was definitely a twitch!" Alasse said. Thranduil looked away from her, hoping she didn't see the panicked look in his eyes. "Why are you so jumpy? That's not like you."

"Enough already." Thranduil said through gritted teeth. Alasse's eyebrows rose. She had an idea. She poked his hip and he yelped. "Hands off!" Thranduil growled. Realization dawned on Alasse, and she could not pass up this rare moment.

"I think I know what ails you." She said in a sing-song voice.

"Oh, no you don't, young elleth!" Thranduil warned. "If you think-" A uproarious laugh erupted from his throat as she poked him again. Alasse was stunned. Her Ada was ticklish? She smirked. Thranduil glared at her. "Alasse. Don't even think about it." He used his fiercest glare.

"Oh, I'm thinking about it." Alasse grinned evilly, lightly skittering her small fingers on his left hip bone.

"Stop this minute!" Thranduil demanded, unable to fight the instant chuckling.

"Hmm, interesting. Are you ticklish here too?" Alasse reached across his lap and around his waist for his other hip.

"Oh, Alasse, no! Keep your hands to yourself, young princess-ahh! Alasse!" Thranduil laughed loudly.

"Aha! So, you are ticklish after all." Alasse smiled smugly.

"I am not. Just..." Thranduil argued. Alasse dug her knuckles into her father's lower sides and Thranduil laughed before he could stop it. "A-ahaha! Alas-hahaha!" Thranduil hollered. Her small fingers were just too dang silky! And her targets were his least guarded, least toned spots on his seasoned, warrior body. He gripped her small hand but she only dug it in further.

Unable to hold himself up from the crazy laughter, he fell back onto the bed. Clambering back on the mattress, Alasse tickled faster. This was too good to pass up! "Stop! Alasse, stop!" Thranduil begged.

"Aww, Ada. Don't spoil my fun." Alasse whined.

"Stop this minute!" Thranduil ordered. Alasse lightly ran her fingers up and down, with spidery touches.

"You need to laugh more, Ada. It's been ages since we've seen you have a proper laugh."

"Is everything alright?" Legolas asked as he stood in the doorway, looking bewildered. "I heard screaming."

Alasse's face lit up. Oh, this was going to be fun! "Legolas! Come help me! Ada is ticklish!" Alasse announced. Legolas gaped. Thranduil? Thranduil...ticklish? No way!

"No, I am noooottt!" Thranduil protested, greatly embarrassed at anyone seeing him sprawled on the bed in this undignified position.

"Really?" Legolas's eyes gleamed with mischief. Then he threw his bow to the side and pounced on the bed and attacked his father.

"You two chucklings will pay dearly..." Thranduil tried to threaten as Legolas pinned him down and started tickling with his sister. "Daahhh! Off! Get off me, you imps!" Thranduil growled, laughing as his naughty kids ran their fingers along his sensitive spots, rendering the mighty Elven king helpless with hysterical giggling. Eru, he had not laughed like this in years, not since...he'd lost count.

"Haha! We've got you now!" Legolas gloated.

"Legolas..."

"Over here, Legolas." Alasse told her brother gleefully. "He squirms crazily if you tickle there!"

"Ahh." Legolas narrowed his eyes, digging his fingers into Thranduil's hip. Thranduil roared dizzily as he wriggled desperately. Legolas tickled harder, squeezing, which all but stole what remaining breath Thranduil had.

"STOP! Enough, please!" Thranduil yelled. "I cannot breathe!" The two younger elves halted but kept their hands planted on his stomach so he couldn't get up.

"What do you think, dear sister? Shall we show mercy?" Legolas cocked his head.

"Just when we have found some new, otherwise unattainable leverage on the king? I think not!" Alasse teased.

Thranduil took the temporary distraction to bolt upright. He caught Legolas by the leg and dragged him over, cutting off escape by throwing his lanky leg over Legolas's back. And he tugged Alasse to his side, holding her to the bed with his strong hand. "You chucklings have had your fun." He said in his sly, deep, menacing voice. "Now, you will suffer punishment!" He poked his finger into Legolas's neck then his sides, and jabbed Alasse in her arm pits. Both elves giggled, squirming like slippery sardines.

"Ada!" They cried.

"Joining up and coming as a front against me, eh? Think again! Oh, you will suffer!" Thranduil growled playfully. He fluttered his fingers between Legolas's shoulder blades.

"Aha! Stop, Ada, stop!" He begged, thrashing his legs back up. Thranduil squeezed Alasse in the same place she'd attacked him and she shrieked.

"N-no, fair, Ada! You're stronger than us!" She giggled.

"Fair?" Thranduil huffed. He released Legolas, but grabbed Alasse and flipped her over onto her back, placing his large knee over her legs and pinned her arms down. Legolas grinned and started removing her boots. "Fair?" Thranduil repeated. "Fair! You call assaulting your king senseless, and humiliating him, and then him not to punish you fair?"

"We were only playing..." Alasse said sheepishly.

"You shall pay for your indignity, princess." Thranduil squinted, grinning.

"M-me? What about Legolas? He attacked you too!" Alasse pointed out.

"But you are the one who got me into this mess." Legolas smiled darkly, gripping one of her ankles. "It's all your fault." Alasse could not outmatch them with strength. There was no way. She was completely at their mercy, something she knew she was not going to get at this point! Oh, she was screwed! She was held down by two of the worst tickle monsters in Arda!

Alasse huffed at Legolas. "Ha! No one said you had to join-" Her sentence was cut off as Thranduil's large fingers found her neck. "Ahahaha!" She laughed, tossing her head back and forth. "Stop, Ada!"

"You've got a lot of nerve, young elleth, making demands after the insufferable measures you took out on your king." Thranduil smirked evilly down at her. His long hair dangled off his shoulders and into her face, making her nose itch and she couldn't even scratch it! She snickered and tried to blow it out of her face, which just made it worse.

"Aaada..." She puffed, trying to shake off his long tresses.

"You shall suffer my methodical torture without complaint." Thranduil said haughtily. "Or I shall increase my impulses." Legolas lightly ran his fingertips along the bottom of her foot.

"LEGOLAS!" Alasse shrieked, throwing her head back. She tried jerking her foot back but her leg was pinned under Thranduil's knee. "Stop it! Legolas! You'll pay-aaah! Ahaha!"

"How's that? Sorry, sister. I can't understand you." Legolas boasted.

"Oh, shut u-Ada!" Alasse hollered. Thranduil poked her neck again, then jabbed her armpits which made her arch her back as she thrashed around. Thranduil chuckled as he lightly tickled her stomach, which sent her into insane fits of giggles. "Oho! Ada! Stop!"

"You'll not order me around, princess." Thranduil sneered, running his hand up and down her sides, up her ribs, then across her abdomen, which was shaking with crazy mirth as she struggled. Legolas was tickling both the bottom of her foot and now also the top of her toes.

"OH NO!" Alasse screeched. Legolas was pure torment spawn with his tickling skills. Out of all her ticklish spots, her feet nearly, literally drove her absolutely insane! "Please, no more! Mercy! I plead mercy!" She begged.

"I do not think you have earned it, elfling." Thranduil shook his head, squeezing her side.

"PLEASE!" Alasse laughed dizzily, but managed to beg with a tone of desperation.

"Well..." Thranduil pretended to think. He poked and clawed her middle one more time. She yelped and he released her hands. She quickly covered herself up. Thranduil removed his knee, deciding she'd had enough. After all, she had her whole life ahead of her and he wouldn't have her suffocate from mere family fun.

Legolas, however, was still fluttering his fingers on her foot. With her other now free foot-thank the Valar!-, she kicked hard at his face, catching him in the nose. "Ouch!" He groaned, releasing her foot. Alasse instantly curled up into a ball.

"Alright then." Thranduil cleared his throat, but failing not to smile. "We've had our fun, time to get back to tasks." He rose from the bed. "I thank you for the mirth, my children. It has been too long since we have played together. But, I am still king and am needed elsewhere."

Alasse was still giggling and panting on the bed. Legolas thought he would risk it and took a jab at Thranduil's lower side. "Ah ah!" Thranduil exclaimed, but quickly drew away from his son's fingers. "None of that! Unless you need another lesson to put you in your place, Legolas."

"No thank you. I'm good." Legolas said sheepishly.

"Mmm-hmm." Thranduil grunted dryly. "Not a word of this to anyone, either of you! Understand? Or there will be dire consequences to face by own hand."

"Yes, Ada." Legolas nodded.

"Yes, Ada." Alasse smiled innocently.

"Good." Thranduil squinted. "Now, I believe you two should be making your way to the training fields." He opened the door to find the hall full of curious, amused, snickering servants. Thranduil's face went crimson.

Did they know?

"What are you all looking at?" He grumbled. "Back to work, all of you! Nothing to see here." Some of the maids and scouts snorted to keep from belly-laughing out loud, with little success. "OUT!" Thranduil bellowed. They all scurried away. "I do know how to clear a room, don't I?" Thranduil mused. Before he completed his next, tedious task, he desperately needed a drink of wine! His children had no idea what they'd just done to him.

"Well, that was fun." Legolas chuckled. "I never knew...I never would've ever believed Ada was ticklish! Not in a million years!"

"Me either! I found out purely by accident." Alasse said. "But, now we have a hold over him that might come in useful."

"Aye." Legolas growled playfully. "That we do. We should put it to good use some time."

"Oh, yes!" Alasse agreed. Legolas stood up from the bed and Alasse punched him right in the stomach.

"Aack! Hey!" Legolas barked, holding his tummy. "What was that for?"

"That is for attacking my feet. You know I cannot stand to have my feet tickled!" Alasse crossed her arms.

"Careful." Legolas warned her. "Well, since you are in such a brutal mood today, I think it would be wise to find a suitable way to release that pent up energy. I know! How about three hours practice instead of two?"

Alasse groaned. "Ohh, Legolas..."

Of course, Alasse still got the worst of it. Why? Because she's a girl and very easy to tickle.
