Hey folks. Trying to get back to writing(ADHD diagnosis explains alot), so figured I would start with one shots like this. Edited it to add a bit more but ultimately it's nothing long. I don't own Frozen, it belongs to Disney and their affiliates. Please support the official release.

Anna sat on the couch, reading the latest novel in her favorite romance series. The protagonist was close to finding out a dark secret about their forbidden lover, but the thrill and anticipation Anna couldn't fully migitate her irritation she also felt. She had bought a special shampoo that happened to have been on sale. Yet after one a mere couple of uses the entire bottle had been rendered empty. Anna knew she didn't wash her hair that often, so it puzzled her.

And the item was now back at the regular price which was more than twice the sale cost. The only other person in her house was Elsa, who was visiting while Kristoff was on a work trip. Anna had accused Elsa yet, but knew that she had done it since she carried around an air of unease as if having something to hide. Anna still tossed around how to confront her.

''Hey Anna, what's tickling?''

Anna looked up from her book. Olaf was standing in front of her with an inquisitive look on his face.

''Oh well, why do you ask?''

''Well I saw something on TV about it. Some guy told his girlfriend that if she didn't tell him where his birthday gift was, and then he started wiggling his fingers and smiling. She looked scared.'''

Anna chuckled. ''Well, people have these things called nerve endings in our skin. And when stimulated, or touched by something it can trigger certain reactions in our brain which is almost always laughter.''

Olaf nodded, looking deep in thought. ''Oh. That's weird, but I also don't have skin, or nerves. What does it look like?''

Anna then got a sly smile on her face. ''Follow me, and whatever you do be quiet.'' Olaf nodded, and Anna got up and walked to down the hall to the guest room. Anna pushed the cracked door open slightly to see Elsa lying in bed on her back. She wore blue T-shirt and dark blue shorts, the clothes not hiding her lean yet curvy physique. She had decided on a nap after a trip to the gym a couple hours ago, a habit that clearly paid off.

''Like I said, stay quiet. Just watch and learn.'' Anna pushed the door open again and walked over to the bed. She sat down and looked down at her sister's slender frame. She then gave a pinch to Elsa's thigh, which caused a slight twitch of the corners of her mouth but she stayed asleep. Then she started skittering his nails over her right foot, which caused her to start to giggle and stir. The older girl then opened her eyes, Anna looking back at her with a mischievous glint to her own.

''An-Anna what are you doing?''

''Well, remember that shampoo I had bought that's somehow is mysteriously all gone. Despite using it for less than a couple weeks. You wouldn't happen to know anything about that would you?''

Elsa's eyes darted for a second, but then she looked back to her sister. ''Well maybe you used more than you should've.''

Anna rolled her eyes, raising a finger and wagging it. ''Oh no, I may be younger but I am not that naive. And you know, lying to me like that can't go unpunished.'' She then jabbed her raised finger into Elsa's stomach, causing the blonde to squeal and start to get up. Anna however then grabbed Elsa's sides and jammed her fingers in causing Elsa to erupt in laughter.

''HAHAHAHAANNAQUI-HAHAHA-IT!'' Elsa said as she tried turning onto her stomach. This only left her in the unfortunate position of Anna having access to her sides and feet as she straddled her. One second she was holding both Elsa's feet with one hand and scribbing over the soles with the other, only to then turn forward and prod or pinch Elsa's sides, along with her armpits.

''Quit? Oh well when you quit ''borrowing'' stuff that isn't yours maybe. Or better yet confess!''

''Noohahaha, hahahaha!''

''Suit yourself.'' Anna started pinching her thighs but Elsa swung her hips and legs knocking Anna off balance. She got to her back but Anna was no fitness slouch her self and pushed her shoulders, delivering some glancing tickles to her neck, weakening Elsa enough .

''Anna yo-hahaha aren't go-haha-nna ger my–EEEAH!'' Elsa's further denial turned into a squeal as Anna started getting at her tummy, which wasn't too hard since her shirt wasn't very long anyway and and ridden up during the struggle. Elsa's flat toned stomach started being assaulted by the scribbling of Anna's fingers. Anna then traced over the lines and indents of her belly before going back to moving her fingers like spiders.

''Wow Elsa, nice to know you stay in good shape. Guys seem to notice too, but if you are this ticklish you might want to reconsider your wardrobe.''

''Shahahat-up!'' Elsa retorted, a blush entering her cheeks. Her midriff was always her most ticklish spot. Aside from the occasional side poke from boyfriends, occasional (jealous) girlfriends being funny or the tickle fights with her sister during their childhood she seemed to have been spared anyone truly exploiting it or her general ticklishness. Until now, all over $5.99 bucks worth of hair soap.

''I can get why you are most ticklish here. They say we can be most sensitive where we are most vulnerable. Lotta guts here, but having no gut might no be helping you in this case.'' She then started poking at Elsa's tummy rapidly, and then a finger wiggled into her innie navel. Elsa's eyes nearly bugged out.

''ANNA-HAHAHANONOT-HAHA-THEREHAHA!'' Elsa tried bucking Anna off but her sister held firm, then starting to tickle her ribs. 'Nuh-uh Elsa. You aren't off the hook yet.'' She quickly scribbled Elsa's neck, then clawing her trim waist, and then aiming back at her belly button again, not quite hitting the mark with Elsa moving around so much but the rapid poking was no doubt effective.

When Anna reached back to her feet again Elsa swung them over and Anna fell off balance. Elsa tried to get up but was grabbed by Anna, who wrapped an arm each over her shoulders and abs and pulled her back onto the bed. Her right arm scribbling her neck, her left hand found Elsa's belly button again, wiggling and swirling about the dimple. The mildly pointy fingernail wasn't doing any favors for knot inside.

''HAHAHAOK I GIVE! IT HAHAHA-WASHAHA-ME''. Elsa screamed, trying to pry Anna's hands away but they always slipped back through to her tickle spots, even switching to her armpits or sides before back to their mark.

''Oh, what was that?''

''I give An-hahaha-na ple-haha-ase.'' Elsa's voice was a bit hoarse. Anna knew this was about at this end, and she wasn't a monster. Well, a non-tickling one at least. ''Ok I believe you''. She got off her sister who just lay there her arms splayed out taking deep breaths, face and midriff pink.

''Well I hope you learned a lesson.'' Anna said, poking her belly one last time before helping her up.

''Ok yes I did.''Elsa said with a giggle. She then noticed Olaf peering around the doorway. ''Olaf you were watching this whole time?''

''Uh-huh. Anna was showing me what tickling was like. And now that's I've seen it, I am grateful I am not human.'' And with that the snowman walked away leaving the two girls alone.

''You did all this to show Olaf what tickling was?'' Elsa said, raising an eyebrow and looking mildliy upset.

Anna bit her lip and looked up. ''Well that too, but you did seriously use something of mine without asking.''

Elsa smiled. ''I know, and I am sorry. It will never happen again.'' The two then hugged, but Anna then looked at the waistbin nearby and broke the embrace. ''Wait, is that a wrapper of the chocolates Kristoff got me for Valentine's Day?''

Elsa gulped. ''It was just one, or two actually. They were really good though.''

Anna glared, but then smiled slyly again. ''Well, they all had a unique fruit filling, and there was one that you didn't steal apparently. Take a guess.'' She tackled his sister onto the bed, sucking in air and moving towards her navel.

''Anna, no I'm so-'''

''PFFFFFFT''!

For the next 5 minutes, laughter and begging filled the room. Moral of the story. Don't touch Anna's shit.
