Work Text:
"Caleb, I'm home!" You singsong, stepping inside the entryway to your apartment.
The familiar aroma of your younger brother's cooking tickles your nose. You're thankful to be greeted by a home-cooked meal after a long day of work, instead of the usual takeout you'd be eating in front of the TV.
"Jie, it's not healthy to eat out too much," Caleb would nag. Not that you even told him about your eating habits. He was at natural everything he did, including keeping tabs on you from hours away at the Aerospace Academy in Skyhaven.
Caleb's borderline stalking and mother-tendencies aside, you can count on him to be providing only the healthiest and most delicious meals for the next week that he's staying with you.
You didn't ask why he wanted to spend his spring break with you instead of his friends at school, didn't ask if he'd rather travel and do actual interesting things instead of playing housekeeper, chef and butler for his older sister back in his hometown. You just accepted it, as per usual, knowing fully well that you'd been feeding Caleb's insatiable appetite for your attention all these years. No matter how many times you encouraged him to go out, be free, he always returned to your side, the ever adoring and attention-starved boy who's attitude was sometimes barely distinguishable from a puppy's.
Although you indulged him a little more than you preferred to, you'd begrudgingly admit in your heart of hearts that you preferred Caleb to be here with you, instead of where admirers and strange women you didn't trust had easy access. You had to be a fool not to notice how much attention the man gets when he's out in public: waittresses making eyes at him, strangers turning heads when he walks by, girls who want to be with him and guys who want to be him.
You'd become rather familiar over the years with the abysmal way he responds to any sort of real or imagined rejection from you. Puppy-dog violet eyes staring down from 6-foot-2, bottom-lip in a pout. Out of place on a face as handsome as his, yet still somehow reeling you into his little mind games time and time again. He'd wrap his huge arms around you, broad torso swallowing your smaller frame, tucking his face into the soft part of your tummy. Unabashed as if there was nothing wrong with a grown young man clinging to his big sister like a young child refusing to be separated from their favorite plushie.
"You don't like me wanting to spend time with you?" Voice sounding just like the sulk that was currently buried in your embrace. He knows you'd go soft, caving once again to the perfectly chiseled face of that boy-turned-man who never fully grew out of his clingy childhood mannerisms. Caleb could always lure you in. Right when you think you have the upper hand is when he makes you realize you just played directly into his hand, again. It was frustrating to no end, but what's a girl to do with her precious little brother whom she raised with her own hands?
You walk into the kitchen half-expecting to come face-to-face with a familiar figure in a familiar apple-patterned apron, but to your surprise, it's quiet. Dinner sits on an already set table for two, steam still rising from the freshly-scooped rice. Your mouth waters at the sight of his signature chicken wings, the warm overhead lights glinting off the glaze that he'd perfected years ago.
If you were any less considerate of a sister you would've sat down and started helping yourself, but you bound upstairs to check the spare bedroom anyway. The door is ajar, but there's no sign of Caleb. Faint sounds reach your ears, muffled and hard to make out but coming from your room across the hall. Approaching your bedroom door, you swing it open without knocking, half-expecting to find him but not at all expecting the shocking sight that momentarily freezes you in place.
"What the hell are you—"
He was in your bed, although he wasn't sleeping. That would've been a much more straightforward situation to resolve.
But no, he's naked with his eyes closed, facial expression lost in euphoria. Soft, rhythmic moans leaving his slightly parted lips. One hand holding your sheets up to his nose, the other… your gaze travels down, eyes burning. You take in the gleam of sweat reflecting off his chest, the blankets ever so slightly bunched between muscular thighs, finally allowing yourself to notice where his other hand was wrapped tightly around an erection that looks about ready to burst.
It takes a moment before he realizes he's not alone.
"Jiejie—"
Smack.
Your body moves on its own to cross the room and swiftly slap him across the face. For a moment, he's stunned, a welt blooming on his cheek where your hand made contact, face slightly turned to the side from the force of the hit. He recovers quickly, meeting your gaze shamelessly from below you in his more-than-compromising state. His expression is smug, devoid of any embarrassment.
"What the fuck do you think you're doing?"
"I thought you'd be home later—" Smack. His response, unapologetic in the slightest, earns him another one.
"That's all?"
His eyes search your face, waiting for you to slip up and start checking out what he currently has on full display. That cocky brat. It annoyed you to no end that he was gorgeous and he knew it, always quick to weaponize his charms against unsuspecting strangers. He hasn't even completely stopped stroking himself, long fingers still caressing what was still an arousal standing at full-mast. You snatch his wrist and he complies, letting the stiff appendage bounce freely against his abs.
"Stop moving, and don't you dare touch yourself."
If there was one thing you could leverage against Caleb, it was the fact that he craved your touch more than a new rescue at the dog pound. The menace he kept—or barely kept— in his pants would come to life at the slightest provocation. You did your best to ignore how he'd get rock-hard from simple things like a long hug or watching TV on the couch, but how long could you play dumb when there was no mistaking the massive thing that you had pressed up against you? You never acknowledged or addressed it, yet never truly discouraged it either.
Walking over to your dresser, you pull out the top drawer and produce a pair of handcuffs and a riding crop. You could practically hear Caleb's breath catch in his throat, and something told you that it wasn't out of fear. A soft moan escapes him as you fasten his wrists to the headboard.
"You're getting too excited for this, don't you have any shame?" You let the riding crop come down on one of his nipples and he jumps at the contact, arching off the bed and tugging at his restraints in the process.
"Don't break them or I'll make you buy me a new pair," You warn, giving his other nipple the same treatment.
"Ah! Ok…" You weren't sure if he was squirming from pain or pleasure, but based on how his erection bobbed against the taut muscles of his abs, he was enjoying this way too much for this to be a punishment. You give your little brother a once-over, although "little" was hardly the word to describe any part of him.
"You've been really bad, you know that?"
He nods.
Smack.
Without warning, you deliver a sharp blow to his dick with the riding crop, eliciting another strangled moan. His hips lift off the bed as they chase the fleeting contact in vain, thrusting up against nothing.
"Use your words."
Smack.
"Ngh…" Smack. "Ah! …I've been bad,"
Smack. Smack. Smack.
"Ahh! —ah!"
Three more lashes are delivered in quick succession. Caleb howls.
"Jiejie, I-I'm gonna cum…"
"You're gonna cum already? That's pathetic, even for you." The words leave your mouth without a second thought. Normally you'd be worried about being too mean, but the way he moans and squirms from just being talked down to is giving you a power trip like never before.
He arches off the mattress again with the next hit. Your fingers flex around the base of his erection, the firm and unforgiving grip holding his climax hostage. His thighs jump and then shudder, confused by the touch that's simultaneously sending him to cloud nine yet preventing him from reaching his climax. Torn between rutting into your hand or jerking away from it, he shakes helplessly in your grasp. You savor the feeling of having Caleb like putty in the palm of your hand. Who knew everyone's favorite golden boy was just a sick bastard behind closed doors, reduced to a whimpering mess at the mere touch of his sister?
"I won't let go until you stop moving, cum without permission and I'll start over."
When it's clear that you can continue, you reward him with another hit, this time closer to the tip. Without giving him time to catch his breath, you deliver hit after hit until he's practically screaming your name, begging to be let over the edge that he's teetering dangerously close to.
"Please, I need to, can I? I'm sorry jiejie, I'll be good…" Glassy orbs look up at you, pleading.
It's a shame you didn't have it in you to be meaner right now, maybe another time. Dragging the flat part of the riding crop from the base of his cock all the way to the tip, he's falling apart almost before the words leave your mouth.
"Cum for me Caleb," you pull back, cruelly leaving him to ride out his orgasm untouched. He groans and throws his head back against the pillows hips rising and thrusting involuntarily in search of the friction he wouldn't find. Friction that you withheld, watching with satisfaction as he desperately calls your name while painting his chest and stomach with liquid streaks of white. The heat that had been building between your legs since the moment you discovered him here leaks urgently against your underwear at the sight, but you try to ignore it. Just a little longer…
You wait just long enough for Caleb to catch his breath, assessing his sorry state. Chest heaving, glistening with beads of perspiration. A mess made on himself, yet if his dick was anything to go by, still needier than ever.
"Cumming just from that…" Your words break him out of his post-orgasm trance. "Do your friends at school know you're this desperate? For your sister of all people?"
His arms are slack against the cuffs holding him to the headboard. Eyes, half-lidded, look up at you in a still-blissful daze.
"Nngh…" You use the riding crop to turn his head to look at you.
"Not answering me? I should just leave you here while I eat dinner by myself." Doing an about-face, you pretend to away slowly. Hearing the jingle of handcuffs against your headboard, you know he's taken the bait.
"Jiejie wait, I'm still…" he trails off. Maybe that previously absent sense of shame is finally settling in now.
"Still what?"
"…still…"
He didn't need to finish his sentence when his fully-hard cock was still staring you right in the face. "You know this is supposed to be a punishment, right? Why are you still asking for things?"
"Please? I'll do what you want, I'll be good, please just don't leave me…"
How cute. Maybe you should've tried harder to discourage him from pursuing his sick fixation on you all these years. To pursue other girls, maybe, but the thought of him romancing someone else left a pit in your stomach even worse than the one left by the realization that you were just as twisted as he was.
Satisfied with his brief display of vulnerability, you reapproach the bed, and he visibly relaxes. This time, you grab your beloved magic wand and climb onto the mattress, using one knee to spread his legs while settling yourself between them. Eyeing the device, he shifts nervously.
"W-what are you gonna do with that?" His usual air of self-assurance gone, he seems to understand that he's at the mercy of your current whims. You opt not to answer, instead filling the room with a quiet buzz as you turn it on, the lowest setting.
You've never done this before, but now is as good a time as ever to figure it out. Remembering a tidbit you saw online about a sensitive spot for men down there, you gently press the tip of the wand against it, not sure what to expect. Caleb tenses up immediately, letting out a half-scream, half-gasp at the sensation. His spread thighs flex, trying and failing to shut out the intense vibration. You're barely applying any pressure, but his cries are music to your ears.
"Aa-aah! Jie—wait—aah! Ah!" His hips writhe, gaining a will of their own, making it harder for you to hold the toy still against him. "It's too much!"
"But you just asked me for more, isn't this enough?" Mean, again. You're not sure if your words are completely registering to him, the way he's thrashing against your favorite sex toy.
"Yes! Yes, it's enough, ah— ahh… it's good,"
"Be a good boy and say thank you."
"Thank you! Thank you jiejie, I—love you—ah! Love you, so much,"
He must really be gone… you could see it as much. Bright violets brim with unshed tears, cheeks tinted red all the way to the tips of his ears. A sheen of sweat on his chest, still dirty with evidence of his earlier sin. Even in his current state, his expression was still one of unbridled adoration. The sight was incredibly satisfying, imbuing you with an urge to push him even further.
To others, Caleb Xia was the perfect student, the model athlete, the ideal airforce recruit. A laid-back guy who effortlessly charmed the pants off of anyone he crossed paths with. To you, he was a needy little rascal. Worshipping the ground you walked on, playing any game, stooping to any level, for a shred of praise from you. Imaginary puppy tail wagging excitedly anytime you were in the room. He showed you sides of him that no one else would ever be privy to, when it came to showing his love nothing was too extreme, nothing too shameless.
Continuing on, your gaze lands on his erection, dark red and laying helplessly against his stomach. The way his wrists periodically tugged against the handcuffs told you without words what he needed.
"If you stop squirming, I'll touch it."
He immediately tries to obey, hips lowering back down onto the mattress. Involuntary shudders still rack his body, but his legs shake with the effort of staying still for you.
"Please, jiejie…"
Your hand looks tiny in comparison next to his erection. Tentatively, your fingers circle around it, barely long enough to fully wrap around the girthy appendage. The touch was slight, gentle even, but just a glance at your hand on his cock is all it took to push him over the edge.
"Nngh! Ngh..ah…fuck…"
So pent-up, so easy. His eyes roll back in his head and his eyelids flutter shut as he releases another mess all over himself. You stroke him through it, fingers running along the silky smooth skin, letting him buck into your hand until you've milked him dry. Some of the liquid dirties your fingers, some run onto the bedsheets, leaving translucent white trails in its wake.
Instead of letting go, you tighten your grip, working his spent cock without mercy. He's crying out, gasping with every push and pull he's granted. He's clearly overstimulated, but he's good for you, taking whatever you give him with pained grunts, toned muscles tightening in time with the brush of your fingers over his overly-sensitive tip.
"Wait—I'm gonna…" A new look crosses his face, maybe one of panic. Intrigued, you push him further, hand working relentlessly.
"Gonna what?"
He doesn't have to answer as another spurt of liquid leaves his cock, this time clear and watery. Your eyebrows raise, amused.
"Aww, did you just squirt? Your boy clit can't take it anymore?"
If his hands were free he might've tried to hide his face, cheeks burning with embarrassment. "I told you it was too much!"
Satisfied, you remove both your hand and the wand, and his body goes slack underneath you. Your hand moves to cup his cheek, damp with sweat and tears, lingering drops still clinging to the long lashes framing his reddened eyes. It didn't look very comfortable having his arms still bound above his head, but he nuzzles into your touch regardless, turning towards your palm and kissing your fingertips.
He's cute like this, nose reddened at the tip, a tender moment amidst the events which just transpired. It reminds you of how hard he cried when you dropped him off at his first day of kindergarten, clinging to you and refusing to let go even when you said you'd pick him up as soon as school was over. You ended up being extremely late to class, having fought an entire war before the day even started to get Caleb to let go, the tear stains on your school uniform as battle scars to prove it. Even after bringing him home that day his eyes were still puffy and tinged with red, sulking at how you "left him". He's grown up so much since then. He made friends, became a top student, got accepted into university… you wonder if he ever grew out of his attachment to you or if he just got better at hiding it so you wouldn't worry about him.
"Jiejie, can you untie me? I'll wash the sheets…"
You had to laugh. "You think we're done?"
His expression shifts. "I can't go anymore, I really can't…"
"I thought you'd do anything for me though?" Hooking your fingers under the waistband of your pants, you let them drop to the ground.
Suddenly his breath catches in his throat, eyes going wide. "Jie…" He exhales, the realization dawning on him.
"Still don't know if you can?"
"No!" He says a little too quickly. "I can. Please, I want to."
"Good boy. You hate disappointing me, don't you?" This level of obedience was more or less unheard-of when it came to Caleb. Straddling him, you pull your already soaking panties to the side, the cold air making your pussy feel even emptier than it already was, craving something warm to fill it. The thought of what you were about to fit inside you made your walls clench in anticipation. Yeah… this is so wrong. You're both so, so wrong.
Lining him up with your entrance, Caleb's eyes watch intently at where you're preparing to take him, almost disbelieving.
"Ready?" He nods, and you begin to sink down, letting out a soft gasp as his tip breaches your entrance. God, it's big, bigger than you were expecting. The slight pain from the stretch makes you falter slightly, but the pressure isn't unbearable.
"Fuck… ahh— you're so tight," He gasps out. "Fuck—slower, slower," His eyes roll back as you press down, the massive thing stretching your walls out, inch by inch.
"You're squeezing me so hard, I-I might not last…"
Your legs nearly give out when he's deep enough to hit something sensitive inside you, but he's not even all the way in yet. Trying to catch your breath, you pause before continuing, bracing yourself.
"Let me help—ah… I can help if you untie me," Evidently, your struggle was noticeable. You comply without thinking hard enough, and find yourself on your back below Caleb in a flash.
"Caleb, wait—" With one swift motion, he's inside you again, sheathing himself to the hilt. You scream, gripping the sheets in an attempt to ground yourself as the sudden stretch of taking him all at once causes you to momentarily see bright spots in your vision.
"A-ah! Slow—down—!" You felt like he was going to split you in half, barely giving you enough time to adjust.
"I can't hold back anymore, jie." He chokes out. His hips set a brutal pace, each thrust kissing your cervix with a force that's turning your brain into applesauce.
"I've wanted this for so long,"
"You feel so, so good,"
"It's so warm and tight, just like I imagined,"
Lewd praises murmured, or rather, moaned, into the crook of your neck as he continued rutting into you like an animal. Your fingernails retaliate, leaving indents on his back as retribution for not handling you with more care. Animalistic instincts take over and you turn and latch onto his neck, sucking a spot between your teeth right under that perfect jawline.
"Nngh.." You're rewarded with a stutter of his hips. Of course he likes the idea of you claiming him in such a visible location. Before you can register what's happening, you're suspended for a moment in mid-air by Caleb's evol, and a pillow meets your lower back as you're placed back down.
Clearly intent on doing whatever he pleased, Caleb pushes back into you, this time at a new angle, hitting your g-spot with a vicious precision. He's already so big that every movement inside you was rubbing against it, causing any and all coherent thoughts to evacuate the premises.
"Fuck—! Caleb, nngh…ugh.. ah!"
"It's so wet, squeezing me so hard, it feels like heaven…" You're quickly losing control, legs shaking as a familiar heat starts building in your core. "I'm sorry… I'm being so rough but I can't help it,"
His words are in one ear and out the other. Each thrust reaches so deep inside you it makes you gasp for air, arms nearly going numb with how hard you're clutching his neck. Caleb is as gone as you are, babbling I love yous and I'm sorrys over and over. You can't even form a complete sentence, the blinding pleasure of him bullying your insides too intense to think about anything else. Perhaps you were always better at repressing the feelings you knew were strictly forbidden between the two of you, especially being the older one and bearing the burden of responsibility. But it never changed anything deep down, you both knew that you needed him secretly just as much as he needed you openly.
Somewhere amidst the haze, Caleb's fingers find the swollen and sensitive nub between your folds. The slow but firm pressure rubbing against that spot forces your walls to flutter around his cock.
"Fuck—don't do that, I'm gonna cum," but you can't help it. The rhythm in his hips falters as he tries to hold back, and you're falling over the edge first, dignity out the window as you start begging.
"Caleb, I'm cumming—please—harder, harder!" He complies as he lets you ride out your climax, squeezing and spasming around his massive cock for everything he's worth. The pleas fall from your lips until his mouth captures yours in a heated and sloppy union. He's following quickly behind, his dick somehow growing even bigger as he finishes again tonight with a couple more strokes. His lips never leave yours, letting your tongues intertwine in a wet embrace as he buries his seed deep inside your womb. Fuck, he didn't even ask, that bastard.
The room is silent save for the sounds of his and your panting. The force of the best orgasm of your life was still reverberating throughout your body, and you could barely think straight knowing it was Caleb out of all people who just made you feel that way. Reflections float adrift in the back of your mind: you needed to have a conversation about safe sex practices, about what just happened, about this… relationship, but you're dozing off too quickly. Strong arms encircle you, tucking you against a warm and sturdy torso.
"Sorry, I didn't mean to cum inside—"
"Where did you learn that?" You interrupt, another matter suddenly reaching the forefront of your thoughts.
"Learn what?"
"The pillow trick."
"Ha. Jealous much?"
"…don't play with me."
"I'm kidding! I'm kidding, you know I would never. I saw it online."
"…"
You relax, then a sudden awareness dawns on you, and it makes you want to hit him again.
"This whole thing. You let me find you on purpose, didn't you?"
A low chuckle.
"Jie, you know me too well."
