All That's Left Unsaid

Summary:

When Caleb comes back home for three weeks in the fall, everything between him and his baby sister changes.

Notes:

This is my first attempt at actually writing Caleb. Please read the warnings as Caleb and reader refer to each other as Brother/Sister!

Work Text:

Waiting for him by the gates with a packed lunch and two hot teas, you rocked back and forth on your heels impatiently as you watched groups of excited cadets walk past. Did they know Caleb? Were they in the same class as him? From your spot under the bright orange tree, you couldn’t make out what type of badges were on their uniforms.

When the flow of students leaving died down, you wondered if Caleb had left already. Maybe trying to surprise him was a mistake. Gran’s voice echoed in your head as you looked down at the sunflower-printed cloth. 

“Why don't you surprise him? To see that look on his face when he finally sees his baby sister!”

This was too over the top, wasn't it? You weren't his real sister. 

“Pips?”

As you whip your head to the left, you finally see Caleb’s shining face and can't help but return his beaming smile. You watched him from a distance; The crisp, autumn breeze flowing through his hair. Your smile faltered for a second at the sudden tightness you felt in your chest. 

Even if it lasted for a heartbeat, this was not the first time your heart had been squeezed by Caleb’s boyish charms.

It was the summer before he left; a record hot day with scorching sunrays and a cloudless sky. Despite the heat, Gran suggested that you two go down to the pool for the day. 

Shaking out the water in his ears like a puppy, you laughed when he sprayed water on you. Your heart may have squeezed, but there was something else. Like someone had lit a match deep within you, burning urgent and settling lower in your abdomen. You let that feeling remain nameless as you never wanted to accept it to be real. 

But late at night in your room as you tossed and turned in your sleep, it returned. The water droplets trailing down his sunburned skin, racing each other through the dips of his abdomen, some pooling in his belly button while others traveled lower under his trunks. Your curiosity always got the better of you. Always got you into trouble. 

Caleb's eyes flared with embarrassment when he realized where you had been staring. To this day, he had never spoken a word about it.

“What’cha staring at, sis?”

Blinking for a beat, you walked up to him before you said anything stupid—handing him his tea and the lunch you packed. Well, it was actually more of a shove than anything. A forceful one at that as Caleb took a surprised step back. 

But the sudden proximity did nothing to help your situation. In fact it only made matters worse for your poor heart. Caleb had always been on the toned side thanks to years of sports in high school. DAA Caleb had more…body to him than before. His chest was solid. When did it get bigger than yours? Was your mind playing tricks on you? 

Now it was your turn to be embarrassed. Sisters were not supposed to notice things like this. 

“You kept me waiting, big bro.” 

“Okay, okay,” he said, raising his arms in a mock surrender. “Let’s eat and catch up, yeah?”

-

There was something in the air that changed that first week he came back from the DAA. The leaves had just begun to change, their colors vibrant as ever as the sun shined through them. In place of the warm days of summer entered a chill that you could not shake no matter how hard you tried to ignore it. 

Caleb seemed to change with the season, but he was still Caleb. Your Caleb. And you were his baby sister. It had always been that way; so why did his hand linger for a fraction too long on your lower back when he scooted past you in the kitchen? Why did you feel his heated gaze through the reflection in the mirror when you brushed your teeth at night? 

And most importantly, why did you crave the extra attention he was giving you? His touches were innocent enough as he never pushed any boundaries, but you still knew it was wrong. Whatever was going on between the two of you was not how siblings were supposed to interact—adopted or not. But that didn't stop you from craving his touch; his warm hands and his strong arms. 

Maybe you should’ve gotten a boyfriend. Maybe you should've lost your virginity to him and called it a day. All these maybes added up in your head but they were powerless to the ache you felt in your heart whenever Caleb wasn't near. 

Sleep was impossible when you could hear him down the hallway—soft groans and heavy breathing that you were certain were not coming from him exercising. It felt wrong listening to him, but as your fingers dipped inside of your tight pussy during for the first time, nothing had ever felt so right.

-

The second week was when he got bolder, more urgent than before. He now hugged you when he came home from the gym, deep and bone-crushing as if he wanted to feel every inch of you. As if he wanted you to be covered in his sweat. He’d accidentally leave the door cracked when he took a shower, hoping you'd at least sneak a peak or better yet walk in on him. 

In return you started to wear tighter t-shirts and shorter shorts to catch his eye, hoping that he would make the first move. The spark was there. Undeniable now as Caleb joined you on the couch, spreading his legs so that his knee slightly brushed against yours. 

As you tried to pay attention to the Saturday morning cartoon you had put on, Caleb slung his arm across the back of the couch behind you. Close enough, but never touching. You were sitting with your legs stretched out, bare feet resting on the coffee table.

“Did you paint your toes last night, pipsqueak?”

“Yeah, do you like it?”

You swore you heard him inhale a bit too forcefully. “Pink suits you.” 

The further you pushed, the deeper you fell into madness. You wanted him to show you how good he could make you feel. And only him. 

-

The third week was nothing but sheer torture as Caleb completely avoided you. Most days he would hide away in his room, the door closed. He would only come out when Gran called him to dinner, but other than that he wouldn't so much as look you in the eye. It was like an arrow through your chest. He was treating you like a stranger. But even then you were sure he treated strangers better than this

Dread filled you as you stared up at the skylight of the attic. Did you misread the signs because you were too horny for your own good? Did he hate you? 

Was he disgusted by you? 

Covering your eyes with your arm did nothing to stop the tears from overflowing onto the pillow beneath your head. You wanted to disappear into the couch, never to be seen again. You secretly hoped you were locked in here, confined to your own shame and allowed to wallow in your own sadness.

The setting sun dipped below the windows, plunging the attic in darkness. You knew that you should have turned on the lamp in the corner of the room but it would've been too much of an effort. The blanket would be warm enough for the night, or so you told yourself as the evening autumn air sent a chill right through you. 

At some point you had fallen asleep, only to be awoken by the creak of the door. 

“Pipsqueak, are you in here?”

“No,” you replied unconsciously. Caleb sighed as he walked to your spot on the couch, the floorboards creaking beneath his feet. 

“I was looking everywhere for you,” he breathed as he sat at the edge of the couch by your feet. “I thought you ran away or somethin’ because of me.”

Sitting up at his words, you saw a glimmer of that unmistakable worry appear in his violet eyes. This is what your selfishness had caused. 

“Caleb.” You reached out to him and grabbed onto his hand. While you expected him to pull away, he held onto your hand as tightly as he could—squeezing hard like you were going to let go at any moment.

“Please let me hold you,” he begged, his voice cracking with desperation. “Just for tonight. Please.”

Before you knew what you were doing, you climbed into his lap and placed both knees at his side. His breathing had stopped for a moment but returned the minute he felt your arms wrap around his neck and your head laying in the crook of his shoulder. 

“Hold me,” you told him. And he did just that—engulfed you into his embrace as he pulled you closer so that your legs almost wrapped around his hips. 

You stayed like that for what felt like an eternity, just staying in each other’s presence without having to speak another word. Though apologies were due, you didn't need them right now—you just needed your brother. You needed your Caleb.

“I’m sorry.” 

His lips ghosted over your bare shoulder, hovering as if he was waiting for something to push him over the edge. As if he was waiting for you to tell him that you needed him just as much as he craved you. 

“Me too,” you whispered, hugging him tighter. 

Those two words were the final snap in the thread that held him back from you all this time. His lips were everywhere your skin was exposed, but never went past the edges of your clothes. 

“Tell me to stop,” he pleaded through clenched teeth. 

“I’ve waited for too long,” you replied, helplessly grinding on his hardened cock. “I need you.”

A flip had been switched in that moment; his deepest desires awakened by your shaky breaths and whiny voice. 

“Do you want Gege to make you feel good?”

All sanity was out of the window now. You were completely and helplessly gone, knowing fully well that no one was going to save your soul now. 

“I need you to make me feel good, Gege.”
