"Just leave it."

"It's Amodar. I can't- mmf…"

"Wha's wrong? Cat got your tongue?"

"Serah."

Lightning didn't have to see well to know that there was a mischievous smirk plastered on her sister's face. Before she considered kissing her back, she snatched the vibrating phone from the night stand as Serah drifted over her and off the bed. Sure enough, the Lieutenant's name flashed across the screen.

"Hello?"

"Ah, Lightning. Thought you wouldn't pick up for a second. Listen, I know it's early…"

Serah returned seconds later, resting her head on Lightning's shoulder. "What's up?" she whispered.

Lightning gave her a quick "nothing yet" before returning the phone to her ear. Serah turned and shifted to rest her chin between the soldier's breasts.

"…have a lot of work to do, and it seems like PSICOM may be stepping in to help us…"

"Right."

Despite the darkness of the bedroom, Lightning made out Serah's scrunched eyebrows and poked out lip. Amodar's long-winded droning buzzed on in her ear, and since it wasn't even four in the morning yet, she found herself agreeing with Serah's confused pout. The Lieutenant had a nasty habit of disclosing information irrelevant to the issue at hand. Still, he was her superior, and despite her half-listening to his too-enthusiastic-for-the-morning tirade, it was only right to throw in an acknowledgement every few sentences or so.

Serah seemed to take it all in stride, but her annoyance was evident. Nimble fingers traced at Lightning's sides, making her quiver under Serah's weight with the rise of gooseflesh. There was the occasional roll of the eyes, a quick nip at the skin between Lightning's breasts, and, yes, of course, a playful moan right outside the shell of Lightning's unused ear. Comical, sure, but uncalled for. Serah was playing dirty.

At long last, it seemed that Amodar had finished his explanation, and the sergeant breathed a sigh of relief.

"Long story short, you can take the day off. Let your squad know, and I'll see you all bright and early tomorrow."

"I see. Yes, sir, I will."

"Get some rest, Lightning."

As the Lieutenant hung up, Serah brushed her nose into Lightning's neck. "You're off?"

A single breath of air whispered from Lightning's lungs as Serah's fingers tickled the underside of her breast. "Apparently so." Lightning's own fingers ghosted down Serah's spine, eliciting the smallest of shudders from the younger Farron. "I need to let my squad know."

"Claaaiire, it's three in the morning. They can wait." Serah's teeth nipped her, just hard enough to coax a rumble from the soldier's throat. "I can't."

The hand on Serah's back marked shape after lazy shape as Lightning formulated the text with her other hand. A simple "no work today" would suffice; it was early as Serah mentioned. Swiping the screen proved difficult with the soft sighs tickling her neck, but Serah was at least nice enough to stay still for more than ten seconds.

Before Lightning locked the phone, Serah snatched it from her and placed it on the nightstand. "Back to me."

"You know you're more important, Serah," Lightning growled, running a hand down to cup Serah's ass.

Bucking into the hand on her backside, Serah grasped at the sheets next to Lightning, expelling a shaky breath into Lightning's neck. "Am I, Claire? Why don't you show me?"

Lightning's brows furrowed, and her gentle caress ceased. "Serah, again?" Not that she was overly surprised, but they'd gone at it, what, four or five times that day? "Don't you need a break? Aren't you tired?"

With a passionate kiss to Lightning's lips, Serah pushed herself off Lightning, moving to situate herself over one leg. "I am. Make me go to sleep."

"Serah-"

The younger Farron ground against Lightning's thigh, most likely aiming to cut her off. Of course, it worked, as Lightning thought of nothing but the slick wetness sliding on her leg. Etro, why did it always come to this? She never could resist Serah's needs.

Serah released a deep-seated growl from the pit of her being. With one hand, she trailed careful fingers down Lightning's neck, breasts, and abdomen, dragging herself along Lightning's leg. Her hand returned to Lightning's neck, and nimble fingers pressed into the skin.

Lightning swallowed hard, feeling her airway constrict under Serah's hand. She bit her lip, clearing her throat before she spoke."Fine. Need some help?"

Serah's pace became oddly timed, mixing short and long thrusts at random intervals. She lost herself in her own rhythm, mumbling to herself about Etro knows what. It took her about ten seconds – Lightning counted – before Serah graced the soldier with a response.

"Uhh… maybe. I dunno. I jus' really wish you could see me right now. Don't you wanna watch?" Serah's grip on Lightning's neck disappeared.

Lightning inhaled a sharp breath as stars flickered in front of her eyes. Those words struck a chord with her as Serah knew just how much Lightning got off to watching her pleasure herself. Serah's words came out slurred too, so she was already lost in her own little hazy world. Lightning reached out, fumbling about the bed for her phone, and then tried the nightstand. Phone in hand, she took in a breath before unlocking it and shining the light on Serah.

Serah must have noticed the light behind her shut eyes, because she made sure she bit her bottom lip and forced out the sexiest fucking moan Lightning's ever heard. Sweat beaded on her forehead, and hair clung to her skin like a magnet. Her breasts bounced, and Lightning found herself reaching up to cup one in her hand, brushing her thumb over the nipple. Serah flashed a teasing smirk at her.

"That… feels really good," Serah sighed, her nails raking down Lightning's abdomen. "But, how's the view?"

Lightning's eyes began to wander at Serah's words. The view was, for lack of a better word, magnificent. Serah's hips gyrated, grinding her heated core against Lightning's thigh. Lightning found herself mesmerized at the expression of sheer lust on Serah's face. Her eyes remained closed, her lips parted, and her head tilted back a few degrees. The phone clicked off, causing Lightning to growl in frustration. Serah chuckled at her as she unlocked the phone once more, dragging the light further down Serah's body. Not a day went by that Lightning didn't find herself marveling over Serah. The girl was petite, sure, but she still had soft curves in all the right places. Lightning, in contrast, sported sharp, angular features and a body seemingly cut out of marble.

Lightning chuckled as she glanced down, watching Serah's hand furl and unfurl at Lightning's belly. "Perfect." The hand on Serah's breast teased and flicked at Serah's nipple.

"Oh… oh yeah? What do you like to see?"

Everything, really. But Serah was trying to tease her, and Lightning enjoyed the effort. Lightning removed her hand from Serah's breast and gave her a swift smack on the ass. Serah swore under her breath, grabbing Lightning's hand and intertwining their fingers. She stopped her pace, probably to prevent herself from driving over the edge so soon. The wetness of Serah's core on Lightning's thigh became more noticeable, and Lightning uttered a heated swear under her breath.

Lightning adjusted the phone's light before she spoke. "All of you. You're beautiful, Serah. You know that."

The smaller girl hummed to herself. "I know. But, ugh, you're so bad at dirty talk this early in the morning."

"You're the one who wanted to fuck at this hour."

Serah huffed. "Okay, but, like. Play along at least? You killed my high, so you better help me come."

A soft chuckle escaped Lightning, one that morphed into a sharp moan at Serah's fingers dancing around her entrance. "Ah… you're such a little minx, you know that?"

"I'm aware. I'm also your sister, your princess, and-" Serah lowered herself to Lightning's ear, grazing the shell with her tongue. "-your little kitten, right?"

"Right," Lightning whispered through gritting teeth.

"So make me purr and watch me come for you."

That just about did it for Lightning. Serah sat back up and started slow grinding on her leg again, throwing her head back. Lightning swallowed a hard lump in her throat, keeping her eyes on the rolling hips before her. One hand crept forward, brushing hair and thumbing Serah's clit. A rough shudder coursed through the girl before she let go of Lightning's other hand to cup and caress her breasts.

Lightning set the phone down at her side, allowing the flash to remain on. Though seeing Serah wasn't a necessity, Lightning was glad she could still make out every part of her. And quite frankly, Serah was beyond sexy as hell rolling her hips like that. Fuck.

"Mmm… Gonna borrow your hand, okay?"

Lightning slid her thumb further down Serah's clit, causing the girl to hiss. "So you're just gonna use me to fuck yourself?"

"Shhhhut up. You like it."

Lightning chuckled, setting her free hand on Serah's hip. She rocked the girl on top of her, grinding Serah against the hand at her clit. Serah jerked her hips more forcefully. She pinched at her nipples, tweaking them under Lightning's watchful gaze. Lightning refused to take her eyes off Serah; if Serah wanted her to watch, then she damn well would.

Serah adjusted Lightning's hand before a guttural groan ripped from her chest. Lightning watched Serah as she fell forward, heavy panting and hot breaths tickling her ear. Lightning waited. Maybe there was some sign Serah would give her about what she wanted to do next; there usually was. But with the shudder that jolted through her sister, she remained unsure. Lightning removed the hand from Serah's hip to cup the back of her neck and run it through the strands of her hair.

Serah pressed her face into Lightning's neck. She attempted to force words out, Lightning picked up, but they emerged in choppy syllables, strained sounds mixed between moaning and crying.

"I'm… I'm gonna come. I'm gonna come so hard, Claire."

Lightning grinned. The grinding became more vigorous. Slick squelching of arousal against her leg blended in with the slight squeaking of the bed frame. Serah's moans added to the mix, creating a sweet symphony of sound Lightning admitted lit her insides on fire.

Teeth sank into Lightning's neck. A shudder rocked her body as Serah's moans were lost, muffled and drowned out into her collarbone. Serah came hard, orgasm ripping through every fiber of her being as she trembled on top of Lightning. A jumbled mess of words expelled from Serah. She spoke confidently, as if every syllable made perfect sense in that muddled head of hers. Lightning couldn't understand her, and instead of encouraging Serah to continue, she removed her arousal-slick hand from under Serah's clit to clean her fingers.

It took Lightning several tries, if one wanted to call bribing kisses 'tries,' before Serah rolled off Lightning's thigh of her own accord, and Lightning shut the phone off. Serah lay at her side, snuggled up into Lightning's chest and neck as she dozed. Lightning chose to ignore the musky wetness atop her thigh; they'll shower first thing in the morning, and she was already beyond tired.

Despite the limited time they've had to spend with one another, Lightning cherished every second she had with Serah over the course of the day. With any luck, it'll be just as eventful with her extra day off. Everything about Serah – her laugh, her touches, her kisses, their bond – made every single endeavor Lightning endured worth it.

And to be honest, she wouldn't have had it any other way.
