------------------------

>You can't sleep.
>Every time you close your eyes, you see the same thing.
>Blue eyes.
>Pink hair.
>That smile.
>You can hear her, too.
>Like a faint echo in your head that won't go away.
>>"Eat your vegetables, Anon."
>>"Don't be late for school, Anon."
>>"Watch out for the traffic, Anon."
>You feel your face burning, the kiss she gave you last night still fresh in your memory.
>Nothing's touched your cheek since. Not your hands, and not this pillow, either.
>Not even a scratch when it was itchy.
>What the heck is going on with you? This never used to happen.
>*KNOCK* *KNOCK*
>You freeze up, shifting your eyes to the luminescent clock on the wall.
>She's here, an hour to midnight.
>Every single night without fail.
"C-come in..."
>The door creeks open, partially lighting your room to reveal your sister.
>Your heart stops at the sight, a common occurrence lately.
>Her yellow pyjamas, decorated with butterflies, look the same as ever.
>Except she didn't do the top two buttons on her shirt.
>Her hair is flowing more straight down than usual, and it looks damp.
>Because she just got out of the shower.
>Like every other time.
>"Are you okay?"
"W-what?"
>She leans over you, her hand touching your forehead.
>"You're not sick, are you? You feel warm."
>The tingles all over your body suddenly turn into sparkles.
"N-NO... I'm fine."
>She gives you one of those heartstopping smiles of hers.
>"You know you can tell me anything, right?"
>You swallow some guilt as stealthily as you can manage.
"I know... I'm fine, really."
>"Alright then."
>You brace yourself as she leans down, landing a kiss on your cheek.
>"Good night, Anon. I love you."
>Your heart restarts itself again as she turns to leave.
"WAIT."

>CRAP, YOU JUST BLURTED THAT OUT.
>"Yes?"
>She spins herself to face you again, strangely light on her feet.
"Uhh... I... I just..."
>What the hell do you say?
>You can't actually tell her, can you? What if she ends up hating you, like mom?
"I feel weird... I guess."
>"Weird?" She sits on the edge of the bed. "Good weird or bad weird?"
"I don't know. Just weird."
>"And you can't sleep?"
>If only it was just that...
"Yeah... s-something's wrong, I just don't know what..."
>You pull the sheets over your face, avoiding eye contact.
>"Say no more."
>She slips under the covers, laying her head on the pillow next to you.
"F-flutty..?"
>Shoulder meeting shoulder, you instinctively move away, only to be met by the wall on the other side.
>THERE'S NO SPACE HERE.
>Not wanting to look like you're avoiding her, you stare straight up, her breath hitting your neck.
>"Oh my, you look tense."
>You flinch as she reaches a hand over your chest, gently pulling you into a hug.
>"There, better?"
>NO.
>"Now, tell big sister what's bothering you. Maybe I can help."
"I DON'T KNOW."
>Liquid starts pooling in your eyes, the hug breaking through your every barrier.
"I-It's like, I have to get away when I'm near you, b-but WHEN I DO... I-I have to get back."
>You hold back a sob, burying yourself in the embrace.
"What's happening to me..?"
>A couple of unbearably silent seconds pass.
>"Oh, Anon..."
>Her grip around you tightens, your face touching her chest.
>"It's nothing to worry about. You're just growing up."
"Th-that's it? You're not mad?"
>"Of course not. I'm glad."
"W-why? I don't get it..."
>She rests her chin on your head, her body bunching up around you.
>"Because this means I can help."

"What? How?"
>Finally getting the courage to look up, you see a blush on her face, even through the darkness.
>But she's also smiling.
>"Well, if you can fall asleep while I'm still here, then there's no problem, is there?"
"I... I guess."
>She lifts your chin with a finger, staring into your eyes.
>"How do you feel right now? Sleepy?"
"Not really..."
>She leans forward, your entire body tensing up as she softly places her lips against yours.
>"How about now? Anything?"
"I... I don't... what was-WAIT."
>You DO feel something.
>Something STIFF.
>You quickly roll out of her embrace, realizing it was poking against her.
"S-SORRY... i-it just happened to-"
>"It's okay."
>She shushes you.
>"You trust me, right?"
"I-"
>Your voice cracking, you settle for a nod.
>Her smile widening, she silently pulls the covers up to your necks.
>You dare to look, seeing her squirming around under the sheets.
"W-what are you doing?"
>"Just some things..." She turns back to you, pulling on your shorts.
>"Can I..?"
>Well... you DO trust her.
>Lifting your lower body, you tug your pants down to your ankles yourself.
"Is that it?"
>She pulls on your shorts.
"W-wait..."
>"You don't have to be ashamed." She whispers, her voice reassuring. "It's perfectly normal."
"A-are you sure..?"
>She nods.
>"Animals have this, too. I've seen it."
>Well, in that case...
>Pulling your shorts down, you kick them and your pants away, freeing your feet.
>You gulp, something else freed as well, and brushing against the covers.
"O-okay... what do I do?"
>"Nothing."
>Pulling you into another hug, she adjusts the sheets again, making sure you both stay fully under them.
>Both of you on your sides facing each other, this hug feels different.
>Her left hand is squished under your body, curling up over your lower back, pulling you into her.
>Her right is draped over your other side and threaded up to your head, her palm pushing it into her chest.

>You're basically locked in place.
>But it's a good place.
>Couldn't you have done this without taking off the pants, though?
"Uhh... FluAAAH-"
>You gasp, a sudden wet and HOT feeling enveloping every nerve ending you didn't know you had, and then some.
"Hnnggh... w-what is... what..."
>This time, YOU squirm around, every new movement providing an indescribable new sensation.
>"Shh..."
>She shushes reassuringly, her arms squeezing you tighter.
>"It's okay. Calm down."
>Breathing through your mouth, you force yourself to stay still.
>"Let me..."
>She slowly grinds against you, providing the feeling in longer, more even doses.
"Wuh... whoa..."
>You begin meeting her motions, the embrace getting tighter with every thrust.
>"There... how do you feel?"
>She stops, letting you do the moving.
"I f-feel... weird."
>"Good weird... or bad weird?"
"GOOD! But... what is this..?"
>"It's my special way of saying I love you when I don't have the words."
>Your heart falters, her walls moving faster around you.
"W-wait..."
>Warning bells sound in your head.
"S-something... coming..."
>She kisses the top of your head, not stopping.
>"Just let it happen. It's okay, I promise."
>Your arms move around her, doing their best to pull you closer together.
>Some kind of end feels close, every passing moment adding to the intensity.
>But she said it's okay, right?
"It's... it's..."
>A single involuntary thrust sparks an explosion in your lower body, sending dizzying waves of pleasure into your head as you spasm in her arms.
>Responding with little thrusts of her own, it feels like you're being pumped.
"Hnngh-"
>Waiting for your spasms to stop, she rolls you on your back, keeping your bodies joined.
"W-whoa... I... that was..."
>"You feel better now? Think you can go to sleep?"
"Y-yeah... I think..."
>Your eyelids drooping, you see one final thing before the slumber takes you.
>Blue eyes.
>Pink hair.
>That smile.
>You don't feel weird anymore.
