CHAPTER TWENTY-TWO

Elsa spent a lot longer in the shower than she needed to — especially given that her hair was in a shower cap. Partly, it was because the very idea of what she had been through made her feel dirty, disgusting. Not to a high degree, and she knew she would be over it in a day or two, but in a way that simply rinsing the evidence off couldn't quite shake the embarrassment.

Why did she care so much? It was such a minor thing, to laugh so hard you pee; it happened to people all the time. Usually to women older than her, but it wasn't that weird. Partly, it was because it was her sister who had done it single-handedly, but partly…

She had peed a lot. That was what was really burning her up, once she got past the initial shame and honed in on it; the other few times something like this had happened, either because of laughing or just holding it too long, she had barely leaked before making it to a bathroom. This was a full-on fountain, and she felt like an incontinent old lady. Or worse, a child. She ought to have better control than that!

However, there was something else bothering her about the whole situation. She didn't want to admit it, even though she might have before the incident. But the longer she stood under the running water, wrestling with herself, the harder it was to ignore. And she had told herself that she would be open and honest with Anna now that they had found their way to each other again. This was really going to put that new policy to the test. Sighing in defeat, she turned off the water and reached for the towel.

Anna was sitting on her bed when Elsa walked back out, kicking her legs and looking deep in thought as she stared up at the ceiling. She turned her head at Elsa's enterance before ducking it again, biting her lower lip. "F-Feel any better?" She asked timidly.

"I do," she said shortly, frowning at Anna. The redhead perked up slightly, turning to give Elsa her full attention. But then she made herself take a deeper breath. "I mean… yes, thank you. Um… listen." Her fingers fidgeted on the hem of her pyjama shirt, and she felt herself getting closer to chickening out. It was too hard to get into a topic this deep.

"I'm sorry!" she blurted. "I should've stopped! I- I should've listened to you." She looked close to tears. "I- I was having fun at your expense and that's wrong. You have every right to be mad at me."

"Well… that's the thing. I was having fun, too! It…" Gulping, she began pacing up and down, feet slapping the floorboards as she continued to fidget. "I haven't had this much pure fun since we were little, you know? And s-something about… like, I normally don't like losing control like that, or… or having anyone tease me. So I was serious that I wanted you to stop, because it was too much, but at the same time I was enjoying that you didn't stop, and it… and I guess I k-kinda liked it, right up until the part where, um, where that happened!"

Anna watched her pace with a look of confusion. "S-So wait, you aren't mad at me?" she asked quietly.

"A little. I mean…" With a roll of her eyes, she admitted, "I was, before my shower, but… I guess you weren't doing anything that bad. After the first time you tickled me, I could have actually made you quit and… and I know you would have listened to me if I had. Right? You would have, right?"

"Yeah, I would've, of course. I was just… caught up in the moment, that's all. And you didn't ask me to stop during the break, so you turning more serious at the end there didn't register right away." She grinned weakly. "It's been so long since we have fun like that and I wanted to make it last."

Finally, Elsa seemed to tire of pacing and sat down on her own bed across from Anna. "Exactly! And… I was angry for a second, and panicked, but then… then when you took a break, and I tried to tell you I had enough, I… I couldn't. I didn't want you to stop! Something about… letting you take control and just… laughing and thrashing around…" Her cheeks heated up more as she spoke, and she folded her arms over her stomach while looking away. "Part of me wanted more, and I couldn't ignore it."

Anna blushed too at the confession. "You, um… it's a natural response, I guess, considering…" She coughed. "Either way, I'm glad you were having fun but it doesn't change the fact that I ignored you asking me to stop, and for that, I'm sorry."

"Alright. Thank you." Her eyes flicked briefly to her before she added, "I wasn't sure I could tell you that it was… fun in a scary way? I guess? Wasn't sure you would understand since I don't understand it myself. It's weird to say you like being tickled, especially when you're not sure you really do."

"Elsa…" Her sister let out another deep breath and leaned back slightly. She looked like she was contemplating something, staring at Elsa with half-lidded eyes and an uncharacteristically serious expression. "I'm about to try something, alright? If you get really uncomfortable, just let me know."

The look of dread on the blonde's face was clear. However, all she said was, "Go on."

Anna got up off the bed and slowly advanced. She kept her gaze on Elsa's face, studying it intently as she settled down on the bed beside her. One hand gently reached out and grabbed Elsa's wrist, nudging Elsa to lay down using her shoulder. She did, blinking up in confusion at Anna, though she didn't seem especially more nervous than before. Anna smiled reassuringly and brushed Elsa's bangs back with her free hand, dragging her nails carefully through the thick mane of white gold briefly before using it to grab hold of Elsa's other wrist. Then she swung a leg over Elsa's body so that she was straddling her stomach and pinned Elsa's wrists to each side of her head.

"Explain to me how this makes you feel."

The elder sister was wide-eyed and staring up at Anna, mouth open a fraction of an inch. Then she blinked and turned away. "Anna, wh-what… what are you doing?" When Anna only waited, she swallowed. "This… makes me nervous. Like I'm not sure what you're going to do next, and whether or n-not I'll be able to handle it."

"Do you want me to get off you?" Anna asked, rubbing her thumb soothingly over the pulse of Elsa's wrists. She was still regarding Elsa with the same intensity of before but her eyes had softened somewhat. Her voice was low, not quite a whisper but getting there.

"Get off? Or what, you'll-" At that, Elsa's eyes snapped back to her sister's, full of fear. She understood fully now. Anna was offering to get off before she did more than just tease her, more than light kisses or comments about how each other looked in shorts. And it terrified her. But at the same time…

It was beyond tempting. Despite the way she had thought of Anna manipulating herself in the bathroom as "sinful", and that she had privately swore she'd never try anything like that herself, the idea of Anna using those same methods on her… it set her heart to thundering in her chest, made her mouth run dry. The same type of thrill was running through her stomach as when they had paused between tickling sessions; she wanted to demand that Anna stop almost as much as she craved to explore the feeling.

"What… would you do if you don't get off?" she heard herself whisper.

Anna didn't answer right away, simply continued to stroke Elsa's wrists. Then she bent over, watching Elsa closely all the while as she started placing light kisses against her neck and shoulders, her lips gracing the skin so delicately that it felt like a butterfly had settled there. The blonde couldn't help the long, shuddering sigh that escaped from her lips. It felt like magic! Her hands flexed to do something, maybe to push Anna away… or bring her closer. But they were pinned down.

"A-Anna…" More shame flooded into her from the way she said that word, but she pushed onward. "I'm… what do you call this? What are you doing to me?"

"Kissing you," was the simple answer. "Do you want me to stop?"

Why couldn't she respond? The word "no" couldn't even come out. All she could seem to do was squirm from side to side beneath Anna's touch, her soft lips. It was just like…

Just like when she was tickling her. Except instead of her feeling a frenzied, laughing panic, this was gentler, full of ponderous heat. She liked it even more than the floor of the kitchens. Anna started pressing her lips harder against her neck, opening her mouth a little to give the skin a light lick. One of the hands holding Elsa's wrists twitched before releasing her entirely, instead gently gliding over over arm until it was cradled against her hip. Anna's eyes fluttered closed briefly before opening again, irises darkening with an expression Elsa couldn't place. The freed hand came up to tuck a strand of hair behind Anna's ear.

"Did…" Her voice came out in a squeak, so she tried again. "Is this… how this works? With you and… and those lesbians?"

"Just let me show you how it works." Anna's chuckle was husky and she pressed her lips briefly to Elsa's, licking her lips lightly but not going any deeper. Elsa's face followed Anna's upward when she pulled away, hungry for more of her. "Do you trust me?"

"Yes," she panted, eyelashes fluttering in surprise at her own answer.

The hand on Elsa's hip slipped under her shirt and simply rested there, Anna's skin warm against Elsa's as her mouth met Elsa's again. Anna's lips kneaded Elsa's and this time, her other hand came up to cup Elsa's cheek. She leaned into the touch, eyes closing for a moment as she found her stomach flexing against the fingertips against its skin. Anna deepened the kiss a little more, lapping at her lips again instantly. A sigh passed from Anna's lips to hers.

She couldn't hold out any longer. Scared as she was of her own actions, Elsa parted her lips, feeling the sigh pass them — and then the tongue that touched her own teeth. A groan of need bubbled up from inside of her as she let her mouth widen more, poked her own tongue up hesitantly for Anna to take. Anna didn't hesitate to gently take Elsa's tongue between her teeth, sucking on it teasingly with a soft moan. The hand on Elsa's waist gripped a little tighter.

'This is going too far,' Elsa thought in the deepest part of her mind, beneath the heat of her growing desire, the satisfaction she felt in the perfect teeth and lips enveloping her tongue. 'It feels so good, but I can't! We can't do this — she's my sister, and she's doing things sisters shouldn't do! I can't let this go on!'

But despite that, she raised her hand to rest on the back of Anna's head, drawing her in even more.

Anna moaned again, the sound vibrating against Elsa's mouth as Anna continued to toy with the tongue still drawn into her sweet mouth. The redhead's legs squeezed Elsa's hips and her hand went from Elsa's waist to tenderly stroking her belly underneath her clothes. Her eyes were closed again. Tingles were shooting down into Elsa's stomach from the teasing of the hand…

Not just into her stomach. More places, ones that she hadn't thought about before. She found herself moaning against Anna's tongue, shaking and whimpering. Anna let out a hum and grew bolder, slipping the hand under Elsa's shirt and slipping her tongue into Elsa's mouth to explore. The mouth opened entirely for her, and Elsa's hesitant leg raised to drape over Anna's hips. She had no idea what she was doing, or why she couldn't listen to good sense and stop, but she was most certainly enjoying every last second.

It felt like forever until Anna pulled her lips away, giving them just enough space to consume oxygen. The redhead's face was heavily flushed and she was breathing as though she had just won a marathon. There was a grin on her face and the hand on Elsa's bare skin never once stopped its slow ministrations.

"Feeling alright?"

"Alright?!" Elsa burst out, panting heavily, face as ruddy as her sister's. "We… what is this? Are w-we-" Her voice dipped lower, suddenly desperate and fearful. "Anna, is this sex? Are we having sex already?!"

While this would usually be the point where Anna would apologise profusely and back off, instead she smiled and chuckled as she leaned back. "No, Elsa," she said patiently, "this isn't sex. Feels good though, doesn't it?"

Visibly relieved, she let out a long sigh. "Oh… because… alright, that's good, it's… yeah." Licking her lips, she turned her eyes up to her sister's. "Does… it feel good for you? M-maybe that's a stupid question…"

"It feels great for me," Anna confessed. "But this is about you right now." She bent down and gave Elsa's forehead a soft kiss. "Do you want me to stop?"

"Not yet," she confessed, looking away. "I hope you d-don't think any less of me, but… I've never felt anything like this before. It's incredible. Everything you do feels so pleasant, in so many ways I've never experienced before!" Then she chanced a hesitant smile. "Do… you mind?"

Anna shook her head and lay another kiss on Elsa's forehead before slowly working her way lower again. Kissing the corner of her eyes and her cheeks before finally kissing her lips chastely. "We're going at your pace, remember? I don't mind."

Elsa was still nodding her understanding when she felt the hand reappear under her shirt, tracing back and forth across her stomach. "O-ooh… you really don't seem to, no."

"Just… being able to touch you like this is enough for me," Anna whispered. She steadily massaged and kneaded her way upwards, grazing a breast to test tentatively at the waters. "Seeing your expressions and hearing you… You really don't understand just how breathtaking you are."

The blonde couldn't speak anymore; not with the foreign hand in her shirt. How was she supposed to weather such a teasing touch?! But her craving for more was overriding her good sense, and she arched her back upward into the hand, prompting Anna to continue. Encouraged, Anna cupped the soft flesh in her hand and gave it a light squeeze, brushing over the hardening nipple with her thumb. The smile on her face was one of complete enchantment.

"A-ah!" Elsa breathed in a shaky voice. It was all she could say, which worried her. Why was it that when Anna took control of her body, she seemed to lose the power of speech? But that wasn't nearly as worrying as the incredible spike of pleasure she felt from the thumb sliding past her her peak. That wasn't supposed to happen. She wasn't supposed to be feeling this!

"I love you, Elsa," Anna breathed out, lowering her head so that her head was resting on Elsa's shoulder, inhaling deeply. "God, I love you so much."

Love? She loved her? Elsa felt her head spinning at that confession. Loved her like a sister? Or as something more? Their actions pointed to the second thing, but she could never assume that. Women didn't fall in love with other women — especially not when they're related.

'But that's not what Anna believes,' the voice in the back of her mind spoke up. 'She's already one of the gays. A sinner. And she doesn't seem to mind sinning with you.'

The rustle of cloth caught her attention and she felt the fabric of her pyjama top begin to crawl up her stomach just as Anna started to lower her head, kissing the skin exposed by her shirt collar. "I want you to relax," Anna said calmly as she straightened herself so she was peering down at Elsa. Soon enough, the shirt was rolled up to Elsa's chin, exposing her breasts to the redhead's heavy gaze.

"I'm going to make you feel really good, Sis."

Tears pricked at the corners of Elsa's eyes as she looked back up at her. All she could do was nod, teeth digging into her lower lip. There should be more coming to her lips, like words telling Anna they needed to put an end to this "experiment", but how could she respond with those glittering teal eyes gazing down at her that way? Almost… hungrily.

Anna bit her lip and her fingers fiddled with the hem of Elsa's shirt as if they were itching to do something. "...What should I do first?" She hummed softly and tilted her head in a way that reminded Elsa of a curious puppy. One who was eying her chest like a particularly yummy treat.

Her hand moved back to the untouched breast and fondled it, teasing the nipple between her thumb and pointer finger while her free hand played with Elsa's hair. Again, Elsa gasped, body trying to curl in on itself out of reflex but prevented from that by the weight of an entire human on her pelvis. Heat burst into her cheeks afresh.

"Elsa…" Anna whispered her name like it was prayer and the hand at her breast groped it slightly rougher than before. The legs on either side of Elsa's hips tightened their grip and she could feel the tremor from her space between them. Even then, Anna never stopped watching her and her hand never stopped its ministrations. The hand in her hair passed through it like Anna was petting her, trying to keep Elsa soothed with the gentle touch.

Meanwhile, Elsa could scarcely believe any of it was happening. Her sister was groping her! Not just by accident, or for a laugh, but twisting her breast in her hand, playing over the nipple… and as much as she had expected to hate being handled so roughly, she didn't. It was exciting. Maybe she couldn't wholeheartedly say that she "liked" it, or sincerely wanted for it to continue, but she was too morbidly fascinated by the thrill that shot through her every time Anna tried some new trick to speak against any of it.

Even more importantly than that, it was having an effect elsewhere. She had tried her best to ignore the feelings — for a very long time, it felt like hours now — but with Anna's legs clamping down around the area in question… a moan floated out of her again, and her hips shifted from side to side all on their own. Anna pressed down with her hips to still Elsa's restless movements but the expression on her face told Elsa that it must've hurt to do so. Her face was flushed, mouth open in a small "o" and her face was scrunched up in a way that suggested pain.

"A-Anna?" she whispered, throat hoarse and feeling dry. She swallowed, then tried again. "Are you alright?"

The redhead shuddered in response and leaned down suddenly, hungrily starting to kiss and nip at Elsa's chest. She moaned loudly. "I'm perfect. You're perfect."

All Elsa could do was writhe beneath her sister's intense touches, mouth open and panting. She was losing her mind! The lips teased her so much that she heard another groan of need falling from her mouth, one that rose at the end to be louder than the rest. She sounded so obscene; that couldn't be her own voice, could it? Not just from Anna kissing her chest!

Anna seemed to be even more spurred on by the noises. She took a sensitive peak into her mouth and suckled it, just enough for Elsa to feel the twinge of pleasure but not enough for it to be completely overwhelming. Her hand, which was still settled on Elsa's other breast, simply caressed it. Anna purred around the nipple in her mouth.

"I'm so… s-so… I don't know!" Elsa panted, fingers digging into Anna's soft red locks as she weathered the treatment. "Your mouth is on m-my- it's- nnhhHH!"

"Shhhhh," Anna soothed, pulling away from her breast only to give it a long lick shortly after. Her eyes were dark. "Still feeling okay?" Elsa only nodded, not trusting herself to say more. A pinch to Elsa's other nipple and another lick. "Good," Anna whispered. "You look beautiful, Elsa…"

Swallowing thickly, she forced herself to whisper, "I do?" as Anna enflamed her body. Her mind wouldn't sharpen anymore, and she found herself only yearning for more of Anna, wrong as she knew it was. Why did she only feel this for her sister? Why couldn't it have been someone else, anyone else?!

"You do," Anna's voice was so reverent and she nuzzled her between her breasts affectionately, "I love you so much," she sighed and closed her eyes, holding Elsa closer.

"I love you, too," she breathed shakily. Unable to keep her hands off of her, she dug all ten fingers into Anna's hair, gripping tightly as she squirmed anxiously beneath her. Anna's fingers twitched and both hands started gliding down Elsa's sides, stroking and petting until they both hovered along the hem of Elsa's pants. They lingered there hesitantly before Anna worked up the courage to dip the tips of her left hand in, caressing the sensitive skin just above Elsa's pubic area.

That was when Elsa froze. At first, she only waited to see what would happen; what Anna meant to do. But when she didn't stop, when the fingers only slid from side to side to test the waters, she began to breathe even faster, swallowing hard before she could find her voice.

"A-Anna… what are you doing?"

"Teasing you," she sang with a tender smile, voice calm and light hearted.

"You… teasing…?"

It was like someone had loudly clapped their hands into the room; Elsa suddenly focused on what was going on and scooted backward on the bed, away from the exploring hands. How close they were to doing something very unsisterly. Panting hard, she whispered, "What were you trying to do just now?!"

Anna's smile faltered and to Elsa, she seemed almost like a little kid again, blinking in confusion after having her hand caught in the cookie jar. "I- I was trying to see…" She tucked a strawberry strand behind her ear. "I just wanted to see what felt good for you…"

"Not my sister trying to-" She gasped, then pushed a fist into her mouth as her eyes got rounder with realisation. How had she been so blind? "Oh… oh, I can't believe what we almost did…"

"Can't you?" Anna looked away with a small frown then scooted backwards herself. Putting distance between the two of them. "I just wanted to help you understand your feelings on this kind of thing a little more, but I just… I got carried away, I guess. Sorry."

Her eyes flicked down to the waistband of her pyjama pants. Anna was going for that. Everything had felt so good that she somehow hadn't realised what they were building toward until it was very nearly too late.

"We're sisters!" she hissed in alarm. "We can't do- that isn't- don't you think it's bad enough that we've been kissing each other so much?!" Her hand slid up into her hair and clenched hard as she babbled, "No, no no no, this can't be happening…"

Anna flinched and cautiously reached over, taking hold of the hand in Elsa's hair. "Stop that, you're going to hurt yourself!" Her voice was gentle but the commanding bite in her tone was clear. "I understand that I scared you, Elsa, but-" She paused and took a frustrated breath. "Did it not feel good?"

"Of course it did! You felt incredible! But it's still sin, Anna! Sin! J-just because something feels good doesn't mean we should do it!"

"Then I'll stop." The redhead said it plainly, as if it was a simple matter of having decided. "We'll pretend it never happened, okay?"

Elsa clutched at her heart and whispered, "Don't you see? I can't. No way can I just… just forget!" Licking her lips, she looked up at Anna. "You… I- I know it's terrible for me to ask, and probably a stupid thing to ask, anyway. But did you… really want to… do that? With me?"

"You probably don't want to hear the answer to that." Anna shrugged and bit her lip, tried to look impassive but there was guilt in her eyes. A deadness that Elsa wasn't used to seeing there. "It's a sin, right? Why should it matter? I'll never… I'll never try something like that again."

"That would be best," Elsa agreed, tears stinging her eyes as she turned away to stare at the wall. Tried to ignore the pounding of her heart, the tingling in the pit of her stomach. "We just… I can barely handle kissing you, I already know we shouldn't do that, either! But…" Her voice got a lot quieter as she confessed, "I don't think that can stop. I'd miss it too much."

"Me too," Anna confessed and offered Elsa a shy smile. "But for now, let's go to bed, okay?"

Nodding, she swallowed hard. "Y-yeah. I mean, yes, I think that's… a good idea, Anna. I'm sorry."

"I'm sorry, too." Anna got up off the bed and started towards her own. She looked torn, her hands clenching at her sides before she simply crawled into bed and turned off her light. "Good night, Elsa."

"Good night."

But it wasn't. It was not a good night for Elsa; she couldn't force herself to fall asleep for at least another hour. All she could do is keep breathing shallowly, clutching at her sheets and trying not to let her sobbing be overheard.

To Be Continued...
