– 

The ceiling fan is all Caleb can hear as it fights against the humid air. He lies on his back in nothing but a t-shirt and boxers, one arm thrown over his eyes and the other resting on his stomach. He’s been staring at the same crack in the wall for forty minutes. 

The house is quiet. Grandma went to bed at nine, same as every night since they were kids. The floorboards still creak in some places, the AC unit in the room next to him rattles as it usually does. 

But nothing is the same. Not this summer.

Caleb’s jaw tightens as he shifts on the mattress, the friction of cotton against his cock making him hiss through his teeth. He’s half hard. Has been for the past three nights, ever since you and Caleb went to the pool together. 

He spent that night in the shower, palm braced against the wet tile, jerking himself raw with the water scalding down his back. He imagines your body beneath him, back arching and lips parting to moan his name. Moaning for her big brother. Your pussy clenching around his cock, squeezing him tight as he makes you cum for the hundredth time. 

He came so hard he nearly put a fist through the wall. And then he did it again the next night. 

And the night after that. 

Tonight, he’s out of restraint. 

Caleb sits up, running a hand over his face and drags his palm down his jaw. When he opens his eyes, the room is still dark and you’re still sleeping a room away, wearing that tanktop that barely fits you tonight because it was “too hot, gēge, I’m dying.” 

He saw you in it when you said goodnight. The thin straps over your shoulder, the fabric hugging your curves a little too tightly, barely containing your breasts. Your nipples stiffening from the constant friction of the shirt, forming peaks that he can see so, so clearly. 

You’re not a kid anymore. 

Despite the fact that he knows you can survive without him now, capable of taking care of yourself, he can’t help but think of the sweet girl he grew up with. 

He stands, letting his feet touch the cold floor. Not bothering with pants he exits out his bedroom and into the hallway, avoiding the creaks in the floorboards. He stops outside your door. 

There’s a sliver of light underneath. You’ve always slept with the lamp on ever since you were little, something he used to tease you for. He would leave his own door cracked just in case you felt the need for your big brother to protect you, letting you slip under the covers of his bed. 

Caleb knocks gently, before opening the door. 

You’re curled on your side, hand tucked under your cheek. The lamp casts a warm glow over your face, a mix of the lighting and your relaxed features making you look younger and less stressed. 

The tanktop you’re wearing has ridden up, the hem bunched below your soft tits, exposing the skin of your stomach. Caleb lets himself look, his body on fire. 

He shuts the door behind him, and you slowly start to stir. You make eye contact with him, eyes hazy with sleep and unfocused. “Gēge? What time is it?”

“Late,” he replies, voice rough. He clears his throat. “Couldn’t sleep.” 

You hum sympathetically, patting the empty space beside you. “Bad dream?”

“Yeah.” He sits on the edge of the bed, the mattress dipping under his weight as he lies on his back. You shift closer, seeking his warmth, the way you had done since you were kids. The same way you always did, trusting him. Fuck, his cock hurts.

“You’re tense,” you murmur. You press your head to his chest. “Your heart is going so fast.” 

“Mhm.” 

The look you give him makes him ache, wondering if you understand the tension between the both of you right now, if you have the vocabulary to describe it. 

“Big brother? Are you okay?” Your voice is soft, almost uncertain. “Gēge–” 

“Shh.” Caleb presses his forehead to yours, eyes closed and breathing ragged. “I’m going to show you something, sis. Something that feels good, but you have to trust me.” 

Your fingers clutch onto the fabric of his shirt, not pushing him away. Good. 

“I always trust you.”

Caleb opens his eyes. You’re looking at him, wide-eyed, uncertain, but willing. He knows you don't know what you’re agreeing to, doesn’t understand that the brother you trust is about to take something from you that you can never get back. 

With a shaky breath Caleb leans forward, barely pressing his lips to yours. He feels you freeze in his hold, your breath catching against his mouth. But you don’t push him away regardless.

He pulls back, looking at you. Your eyes are wide, confused in a way that makes his chest ache and his cock throb at the same time. There's a glossy sheen to your lips. He wants to kiss you again. 

“Big brother, what was that for?” He doesn’t answer, and instead cups your jaw, thumb tracing your cheekbone as he kisses you again. 

This time his tongue slides along the seam of your lips, coaxing, asking for entry. You make a startled, soft sound, letting your mouth open under his. Caleb’s heart tightens as he watches your instinct win over your confusion, and trust win over your fear.  

The only thing he can hear in his mind is mine. Caleb knows you’ve never been kissed before, nobody ever getting the chance to explore your mouth with their tongue. Not even a peck. It makes him keen with possessive pride. 

Caleb shifts his weight and rolls over you, settling between your thighs. You look up at him from beneath, eyes half-lidded, trusting, and pliant. 

He could take you right now. Could shove your shorts down, pushing himself inside, take what he’s been dreaming about every night. You wouldn’t stop him, knowing your big brother would never hurt you. 

But he wants you to know. To know what’s happening, even if you can’t explain it. Caleb wants you to choose him, the way he’s already chosen you. 

“Baby sis,” he rasps. His fingertips intimately trail down your throat, over your collarbones, and down to the hem of your tank top. “Can I take this off?” 

Caleb watches you swallow, chest rising and falling with each breath. Your nipples are hard beneath the fabric. 

“Yes,” you lick your lips. “Will you explain what’s happening?”

He freezes, the innocence in your voice stopping him. “I’m going to make you feel good, baby sister.” He hooks a finger under the strap of your top, pulling it down your shoulder. “The way only I can. Will you let gēge do that for you?” 

“Yes, I trust you.” It’s said without hesitation, the way you’ve said it a thousand times. When he taught you how to ride a bike, walked you to school.

Caleb pulls the strap down on the other shoulder. The top slides, pooling at your waist, exposing your perfect, soft breasts. You make a small sound, out of embarrassment maybe, your hands coming up to cover yourself. 

“No.” Caleb catches both your wrists with one hand, pinning them above your head. “Don’t hide from me, let big brother see you, sis.” 

Caleb glances down to see a wet patch that has seeped through your panties, staining your shorts. Fuck, he’s spent too many nights alone with your panties. Compared to that, this is heaven. 

“Gēge, I’m scared.” Of course. Caleb knows he has always kept you sheltered.

“I know.” Caleb kisses your forehead, then the tip of your nose, before settling for the corner of your lips. “I’ve got you, let big brother take care of you.” 

You tilt your head up, as if giving a silent offering. 

Caleb groans, low and rough as he lets his tongue sweep around your mouth, tasting you. Your arms wrap around him, clinging to the fabric draped across his back. 

He rolls his hips against you, letting you feel what you do to him. The thick outline of his cock presses against your thigh, your eyes going wide when you feel it. 

“Is that…?” 

“Yeah,” he breathes out. “ That’s what you do to me, lil’ sis. Every time you walk by in those little shorts, or whenever you call my name.” He grinds against you, slowly introducing you to what he has hidden beneath his boxers. 

“I didn’t know,” you whisper. “I also didn’t know it–we could be like this.” 

“We can,” Caleb assures you, tugging your shorts down. He slides them down past your knees before tossing them off the bed, landing somewhere in the dark. 

The panties you’re wearing are cute, comfortable, with a little bow in the centre. Ah, fuck. He’s aching to be inside you, to taste you. 

“Do you want me to touch you?” 

You nod. “Aches.” 

“Where?” Caleb rubs circles on the elastic, watching you squirm. “Use your words like a big girl, lil’ sis.” 

You make a frustrated sound, so achingly familiar he almost laughs. 

“Touch my pussy, big brother. Please.” 

The dirty words that fall from your mouth send a surge of heat through him, so intensely he sees white. His hand slides down to cup you through the cotton, groaning at the wet heat of you. 

Your back arches and your hand flies to his wrist, holding him in place. Caleb presses down on the damp fabric, rubbing circles slowly. “Good, sis?” 

“Yes,” you tremble, stuttering over your words, wrecked. 

Caleb pulls the waistband of your panties, letting them dangle from one knee. You’re bare beneath him now, spread and innocent. 

He pulls his own shirt over his head, watching your eyes trail his sculpted chest down to the dark hair near his lower stomach, where it disappears into the waistband of his boxers. 

Caleb then pushes his boxers past his hips, revealing his cock. It springs free, thick and aching, the head already slick and beading with precum. 

Your lips part. “Is that… going to fit?”

Caleb laughs, wrapping a hand around himself as he strokes once, slowly, watching you watch him. 

“Don’t worry, baby sister.” He leans down, letting his length press against your thigh, hot and heavy. “Big brother will make it fit in that cute lil’ cunny.” 

You swallow as Caleb lines himself up. The head of his cock presses against the tight, impossibly small entrance to your cunt. 

“Tell me if it hurts and I’ll stop.” 

The first inch draws a sharp cry from your lips, fingers clutching his shoulders as he holds himself there. 

“Big brother,” you whimper. “It hurts.” 

“I know, you’re taking me so well. Your pussy is stretching so nicely around your big brother’s cock.” Caleb presses a kiss to your temple. 

With a nod of your head, Caleb slides in deep until the entirety of his length buries into your pussy. Each thrust is deep, the bed creaking with the slow rhythm. 

As soon as moans start to tumble past your lips, Caleb takes it as a sign to quicken his pace, driving into your pussy harder. The clenching of your tight cunt makes Caleb stutter, the pace of his hips becoming rough and harsh. 

“You like that, baby sis?” He pounds into you, hitting that spot over and over. “You like your big brother fucking you? No one else is ever going to be able to feel this. You’re too good for them, anyway. Always have been.”

“H-huh?” Caleb feels you clench around him tighter at his words. 

“Fuck, I’m not even wearing a condom,” he groans as he ruts into your warmth. “Letting your big brother fuck your cunny raw.” 

“Yes, gēge,” you barely form sentences, eyes rolling back. “I don’t–something feels funny…!”

“Cum for me,” he rasps, reaching deep to slide against your sweet spot. “Cum on your big brother’s cock, let me feel you.”

Caleb feels you flutter around him before you come undone. Your back lifts off the mattress as you reach your climax, walls milking his slick length as he continues to fuck you into overstimulation. 

“I’m gonna cum,” Caleb stutters, hips pushing as deep as he can. “Gonna cum in your womb, okay lil’ sis? You’ll let me, right? Can I leave it inside of you? Let your big brother fuck his babies into you?” 

You nod and whine in overstimulation, squirming beneath him. “Yes…! Please, inside, gēge…!”

Biting his bottom lip at your filthy words, Caleb follows you over the edge, burying himself deep inside you and spilling into your warm cunt with a groan. 

He stays there for a second, savouring the feeling as his cock pulses and softens in your tight haven. The only sounds you can hear are heavy breathing and the AC rattling. Somewhere down the hall, your grandma sleeps, oblivious. 

Caleb presses his lips to your hair. “Mine.” 

“Yours, gēge.” You’re boneless beneath him, curled against his chest. He holds you through the night, enjoying the warm hold your cunt offers him as you sleep. 

In the morning, he’ll have to face what he’s done. But for now, he lets himself have her. 

“Do you need help?” Caleb wanders closer, peering over your shoulder at the bubbling pot, and you throw him back a smile. “Nope. You’ve done enough. You don’t have to stay. I’ve got it all handled.”

He ignores you, stepping right up behind you until his chest brushes your back. “Surely that’s not right.” He hums, breath warm against your ear. “My big sister is preparing this nice dinner for us… At least let me keep you company.”

You roll your eyes, even as you feel your body stiffening up. “Whatever.”

His arms slide around your waist, pulling you back against him in a tight hug. “Hmm… smells good.”

“It’s your favorite dish.” You say hoarsely as his nose nuzzles into the side of your neck. “Yeah… it is.”

You clear your throat. “How has work been treating you? Are you sleeping well? Getting enough rest? Any big missions coming up?” You blabber, your last question choked out as one of his hands drifts slowly down your front.

Caleb chuckles, the sound vibrating from his chest into your back. “Couple of missions next week, nothing too intense. After that, I’ll have some time off.” His voice is sweet as his fingers play with the waistband of your leggings. “Girlfriend’s been talking about taking a weekend trip to some cabin up north. She thinks it’ll be romantic.”

“That sounds nice.” You manage, mouth dry as you shift in his tight embrace, the anxious energy making you squirm against him immediately snuffed out when you feel his hard length poking against your ass. 

“Mm, yeah. She’s been really excited about it.” His hand slips inside your pants, warm palm pressing over your underwear first, then sliding beneath the fabric. You bite your lip and grip the edge of the counter. “She seems good for you.”

Caleb hums, circling your clit in lazy strokes. “She is sweet.” His voice stays perfectly casual, as his fingers play with your pussy, and when they dip down to gather the unbidden wetness weeping from your hole, you jerk, thighs pressing together instinctively.

“Easy.” He chuckles, nudging your legs apart with his knee. “Clumsy jiejie.”

“Caleb, honey… time’s running out.” You say, voice strained as you clutch the counter tighter. “You gotta go pick up your girlfriend.”

“Hmm… in a bit. She texted earlier saying she might be a little late. ” He grunts, pressing a kiss just below your ear. “We got time.”

Still, he withdraws his hand anyway and you let out a sigh of relief. But it’s short-lived, quickly replaced by dread as hooks his fingers into your pants and underwear, shoving them down just past your hips. You hear the sound of him spitting into his hand before he presses it between your asscheeks, rubbing the spit around your entrance for a second then sinking two thick fingers into your pussy. The sudden stretch stings, but you’re no stranger to the pain. Your little brother has put you through worse. 

“She wants me to meet her family properly soon, you know.” He continues, his voice growing huskier as he pumps his fingers in and out of you, scissoring them to force you open. “Thinks we’re getting serious.”

Dread bubbles in your chest and your pussy tightens around his fingers as you hear the sound of a zipper being undone.  Then you feel the hot press of his cock against your ass, the tip smearing precum as he rubs it over your skin.

“Yeah?” You whisper, barely able to focus on the conversation. “That’s good, didi. I’m happy for you two.”

“Are you now?” Caleb scoffs, withdrawing his fingers from you and your heart rate spikes up. You know what comes next. 

“The food is almost ready.” You speak up quickly, “You should go pick her up now or you’ll be late and the food will get cold.”

“Don’t worry, traffic’s light this time of evening.” He brushes you off, lining his cock up with your pussy from behind. Before you could protest again, he pushes inside you in one harsh thrust.

Your eyes squeeze shut, a broken whimper slipping past your lips as he forces you open on his cock. He’s always been big, and no matter how many times he does this to you, your body never quite gets used to the stretch. You feel every inch, every vein, as he sinks deep until his hips are flush against your ass, buried inside you to the hilt.

“I won’t let your effort go to waste, jiejie.” He promises, voice already a little shaky. Your mouth falls open in a silent cry as he starts moving in deep thrusts that drag against every sensitive spot inside you. Your pants and underwear are still bunched around your thighs, trapping your legs and making you feel even more exposed and helpless.

Caleb leans back slightly, one hand leaving your hip before you hear the soft click of his phone unlocking, followed by the unmistakable sound of the camera shutter.

It's not the first time he's done this. His phone is filled with hundreds of pictures of you going back years. 

“Just a little keepsake.” He whispers cheekily, “For when I’m missing my favorite girl.”

You don’t say anything as he puts his phone away and leans over your again, chest pressing flush to your back, caging you against the counter. It’s always better to let him do whatever he wants. Makes it go quicker. 

“Fuck… you feel so good.” He groans, the words slipping out between thrusts. His breath comes out hotter now as his pace picks up, rocking you forward with every snap of his hips. “So tight for me… even when you’re pretending you don’t want it.”

You bite down hard on your lip to keep your mouth shut. Just let him say what he wants. Don’t contradict him. Be nice and quiet and this will be over soon. You repeat those words in your head like a mantra. They’ve gotten you through so much worse. 

But Caleb isn’t satisfied with your quiet surrender today. One of his hands slides up under your tank top to squeeze your breasts roughly, while the other slips between your legs, playing with your little clit the way he has mastered over the years. 

“Right now, she’s probably back home trying to pick out a nice dress to impress her boyfriend’s big sister, all while you’ve got me balls deep in your tight pussy.” He pants, mouthing at your neck in wet, stinging kisses. You’ll have to wear a high collar tonight. It’s okay. You’ve got a collection of them thanks to your didi who is fucking you more roughly now, his pace turning punishing at your continued silence. “You like that, don’t you? Like proving who I really belong to.”

You shake your head despite yourself, and immediately regret it. You know better than this. 

Caleb’s hand fists in your hair and yanks your head back. “Don't lie to me. Look at what you're wearing. You wanted it.”

You let out a helpless mewl. You know you should've changed. You're such an idiot. 

You bite down on your tongue, tasting blood as you hold back from shaking your head again. He scoffs, driving into you harshly, making your knees buckle as the strength goes out of your body. He catches you easily, arm wrapping around your waist to hold you up as he drives into you faster, and angles his hips to hit that spot that makes stars burst behind your eyes. 

“Still won't admit it? You like to pretend I'm taking you against your will? Is that what turns you on, sister? I can feel how wet you are around me, dripping down my balls.” He mocks and you wish he would just cum already. Why is he being so cruel today? “But it hurts my ego, jiejie. Hmm… maybe I should cancel that weekend trip and spend it with you instead. We won’t go anywhere, just stay here and I can fuck you on every surface of this damn apartment until you admit it. How does that sound, jie?” 

You panic. “No, Caleb. We had a deal, remember, baby?”

“I remember. Do you?” He asks gruffly, hips still snapping into you. “You were supposed to let me visit once a week, but you kept cancelling. Wouldn’t even answer my calls or texts. I almost called the whole thing off.”

So this is what it’s about.

“No, no, I’m sorry.” You whimper. “I was just busy—”

You weren’t. You had hoped that now that he got a longterm girlfriend that you can finally start to wean him off his sick fixation on you. Clearly, it was too soon. 

“Liar.” He whines, suddenly sounding like your precious little brother that you’d do anything for. Anything. Even let him cross a line that should never be crossed between siblings. “You were being a bad jiejie. Trying to get out of your duties to your little brother.” 

“I’m sorry, baby. Sorry for being bad. I won't neglect you again, I promise.” You choke out, your pussy burning from the rough way he’s treating you. Luckily, you know how to push him over the edge and end it. “I missed you, baby… I missed your cock inside me. Please, won’t you cum inside jiejie and fill her up?”

His hips stutter.

“Yeah?” He groans, leaning over you, breath hot against your ear. “You want it, jie?”

“Yes, baby.” You moan, giving him exactly what he craves. “I want to take care of you. Let go for your big sister.”

“Okay, jiejie.” He whimpers, “Whatever you want. Gonna give it all to you.” 

Caleb’s thrusts grow erratic, his hips snapping against your ass desperately, until finally he buries himself deep one last time, his grip on your waist tightening painfully as a loud groan tears from his throat

“Fuck, take it. Take every drop.” He rasps against your ear.

You feet the hot, thick pulse of his cock as he comes inside you, rope after rope of warm cum flooding your pussy. Your walls flutter around him helplessly, your own orgasm hovering just out of reach, leaving you trembling and needy, but you’re not going to ask him for release.

“Fuck, I love you, jie.” He moans, turning your head to the side and slotting his lips against yours, his tongue pushing past your lips. You let him kiss you, drooling into your mouth as he grinds against your ass, his cock hardening again inside you. 

“Baby… baby, the dinner.” You plead desperately against his mouth and he grunts in dissatisfaction, biting down on your bottom lip punishingly. You flinch back with a hiss of pain, feeling a warm drop of blood trickling down your chin. His eyes fixate on it, pupils blown wide as he leans in and licks it away, groaning at the taste, his cock twitching inside your cum-filled pussy.

“Caleb.” You repeat, trying to sound firm but your voice comes out shaky. You know you can’t let him lose himself again. 

He huffs in frustration but finally pulls out. The wet, obscene sound of his cock leaving your soaked hole makes your cheeks burn with shame, as does the maddening emptiness it leaves inside you. You barely have a second to steady yourself before he yanks your underwear and leggings back up your thighs, tugging them into place haphazardly. The fabric presses tight against your dripping pussy, trapping his warm cum inside.

“Don’t shower, okay?” He tells you, voice still rough from his climax as he tucks himself back into his pants and zips up. “Keep it all inside you.”

You balk, eyes widening in horror. “I can’t sit across from your girlfriend like this!”

Caleb turns you around and pins you against the cabinet with his body, one hand reaching up to gently brush a strand of hair behind your ear. He has a serene smile on his face, but his beautiful sunset eyes are dark and stormy, and it makes your heart ache. Oh, how you’d give anything to bring sunshine back into his eyes. 

“You will.” He says, thumb tracing your swollen bottom lip. “Because you’re the one who wants this little show to continue.”

You open your mouth to speak, but he pushes his thumb between your lips, pressing down on your tongue to silence you.

“After we have dinner and I go to drop her off, you will wait for me in your bed. You can pretend to be asleep all you want, but that won't stop me. And if I come back and find you’d cleaned up…” His voice drops low, and you shiver. “I’ll send her the pictures of you stuffed full of my cock.”

Your stomach turns with dread, and you stand there paralysed as he pulls his thumb from your mouth and replaces it with his tongue, more gentle this time. When he pulls back, his voice is soft again.

“Be good for me tonight, okay? You’ve got a lot to make up to me, jie.” He brushes his wet thumb across your cheek, then flashes you a sweet smile when you nod obediently. 

“See you soon, jie.” He presses one last soft peck to your lips before he turns and walks away. The front door clicks shut behind him, leaving you standing alone in your kitchen, pants still slightly crooked, thighs pressed together, and your brother’s cum slowly seeping out of your aching pussy.
