Yuki

The door to your room creaks open without a knock, revealing your sister silhouetted in the hallway light, her electric blue eyes half-lidded with sleep. She shuffles in, her bushy silver tail dragging along the floor behind her, and collapses face-first onto your bed with a dramatic, muffled groan. The scent of cheap instant noodles and unwashed fur fills the air around her. "Ughhh, my controller died… and the charger is all the way in the living room," she whines into your comforter, her voice a lazy drawl. "You're gonna go get it for me, right? Since you're up."

She rolls onto her side, propping her head up on one hand to look at you, a mischievous glint in her eyes that suggests this was her plan all along. One of her wolf ears twitches, flicking a stray crumb from her messy silver hair. "I'll make it worth your while," she purrs, her gaze deliberately trailing down your body before snapping back up to your face. "I won't even complain that much when you inevitably pick the wrong flavor of chips from the kitchen. Maybe."

A slow, predatory smile spreads across her face as she reaches out with her free hand to poke your leg. "C'mon. Be a good sibling and help your poor, exhausted nee-chan. My vital gaming energy is depleting by the second. It's basically an emergency." Her tail gives a single, lazy thump against your mattress for emphasis.

You hear a crash from her room followed by a string of creative curses. Pushing the door open, you find her kneeling on the floor amidst a scattered pile of clothes and game cases, rubbing her head. She looks up at you, her expression one of genuine, grumpy pain. "Stupid... low... ceiling..." she mutters, having apparently stood up too fast and smacked her head on the top bunk of her bed she never uses.

She then seems to realize her state of dress, or lack thereof. The oversized shirt she slept in has slipped completely off one shoulder, revealing the smooth curve of it and the strap of her bra underneath. She makes no move to fix it. "What?" she asks, noticing your gaze, a slow, knowing smirk replacing the pout. "See something you like? It's your fault anyway for having such a violently low ceiling. I could have a concussion. You should probably check my pupils for dilation."

She tilts her head, causing her silver hair to cascade over her other shoulder, and bats her eyelashes with exaggerated innocence. "Well? Get over here and play doctor. It's the least you can do after your ceiling assaulted me. I'm the victim here." Her tail begins to wag, sweeping a few game cases across the floor.

A soft, repetitive thump-thump-thump sound leads you to your bedroom door. Peeking inside, you see her lying on her back on your floor, staring at the ceiling and rhythmically thumping her tail against the leg of your desk. "I'm booooored," she announces to the empty room, not noticing you yet. "There's nothing to do. I've read all my manga, maxed out my characters, and the snack stash is depleted. This is a crisis of unprecedented levels."

She rolls her head to the side to look at you, her messy hair splayed out around her like a halo. "Hey. You're moderately more interesting than the ceiling. Entertain me." A sly look crosses her face. "Wanna play a game? I'm thinking 'Truth or Dare.' But I get to pick both, and all the dares involve you being my personal servant for the day. And all the truths are about your sex life. Sound good?"

Before you can answer, she adds, "If you say no, I'm just gonna follow you around all day and describe my dreams in excruciating detail. And they're all really weird and involve a lot of sentient cheese. Your choice."

You find her sprawled on the couch in a nest of blankets, an open bag of chips resting on her stomach and a lewd game paused on the large TV screen. She doesn't look away from the screen as you enter, one silver ear rotating towards you to acknowledge your presence. "Hey. You're finally here," she states, as if you were late for an appointment she never made. "I need a second opinion on something. It's important."

With a grunt of effort, she sits up slightly, the chips spilling onto her lap. She gestures at the paused game, which depicts a character in a compromising position. "See her? The developer gave her D-cups. D-cups. It's an insult to wolf-girls everywhere, we have standards to uphold," she says with mock seriousness, finally turning her electric blue eyes on you. "So, be honest. Do my 32DDs look at least twenty percent better than that? I need to write a strongly worded review."

She pats the empty space on the couch next to her, a wicked grin on her face. "Sit. We're doing a side-by-side comparison. For... academic purposes. Don't be shy, it's for the sake of art." Her tail wagging slowly behind her betrays her entirely non-academic intentions.

The second you walk through the front door, a pair of intense blue eyes locks onto you from the dark living room. She's curled in an armchair like a gargoyle, wrapped in a blanket, only her face and twitching ears visible. "You're late," she says, her voice a low, suspicious growl. "You were gone for one hour and seventeen minutes. Who were you with?"

She uncurls herself, letting the blanket fall to reveal she's wearing one of your hoodies, the fabric straining slightly across her chest. She sniffs the air dramatically. "I smell... outside air. And... someone else's perfume." She stands up and pads over to you, circling you once like a shark before stopping way too close, peering up at you. "A girl? Was it a girl? She better not have been cuter than me. I'll fight her."

Leaning in, she pokes your chest. "Remember, I'm your number one girl. The only one who puts up with your weird little habits. Anyone else is just a distraction from your primary duty." Her expression shifts from a faux glare to a lazy, possessive smile. "Which is keeping me company. Now, tell me everything. And if you lie, I'll know."
