Work Text:
As Sunday creeps out of his room and begins to approach yours, he sighs.
Perhaps it's the sickest sin there is, to sneak into his littlest sister's room and take her, but if he thinks about it for a few more seconds, he realizes something: it'd be a worse sin if he didn't take you. You're his baby sister, so of course you belong to him. You were meant to be with him. His precious little bride, and you were none the wiser to it.
11 years old, and already his wife.
Sunday knew it was disgusting, but it was too late to back out of now, because he was already at your door. He slowly entered your room, taking notice of your unconscious figure. You were so adorable, he couldn't help himself. "Hello there, sweetheart." Your brother spoke, carefully shutting the door behind him and climbing on top of you.
He knows he has to do this.
You shift slightly under his gaze, causing him to smirk. "Shhh, darling, it's alright. I'm not going to hurt you." Sunday whispers, smoothing his fingers through your hair, adoring how soft it was. "I know you love what I do to you, too." He said, pulling back to unzip his pants, yanking his cock free— hand gripping his shaft, eyeing your pretty lil' face. "Don't you, sweetheart?" He cocked his head.
His eyes transfixed on the gentle rise and fall of your chest, almost at the cusp of puberty. Sunday couldn't wait for your first period, although he knew he would miss your underdeveloped body. Sunday lifted your nightgown, using his other hand to stroke your tits while jacking off. "I have such a cute little sister.." Sunday mumbled, his thumb rolling around your nipple, causing a whine to fall from your lips.
"Ah..." His cock twitched from the noise, precum spilling from the head. You were so precious, and he couldn't help but lean in to inhale your intoxicating scent. "Don't worry, darling. Your big brother will be gentle." Sunday said, teasing your nipples one last time before moving his hand between your legs, sliding your panties to the side and groaning from the sight of your prepubescent cunt.
Slowly but surely, he peeled your panties down until they met your ankles, readjusting himself on top of you. Sunday's hands went back to your chest, fondling and squeezing your skin, as soft as porcelain. He breathed, grinding his hips forward, cock aching to fuck that sweet cunt from yours, and after a few seconds, he slid himself into you. "Ahhh... Fuck." He hisses, feeling how you immediately tightened around him.
You gasp from his cock entering you, fluttering your eyes open for a second before immediately closing them. Sunday's stomach tightens, voice caught in his throat as his hands squeeze your hips, relishing in the size difference between you and him. "It's okay, sis. You don't have to be awake for this." His fingers brush across your cheek, kissing your forehead. "You're so tight..."
His cock is almost as big as your thigh, big enough to poke through your tummy. You moan in your sleep, clutching at your brother. Sunday continues to thrust into your little body, loving how peaceful you look. "Such a good little sister for me, fuck." Your pussy is so warm, drenched completely for him as he pushes himself in and out, coaxing more noises from you. The bed gently rocks back and forth with his movements, and he tenses, knowing he can't get caught.
Sunday wonders what everyone would think, what Robin would think if she discovered her brother raping their little sister in your own bed. "I love you, sweetie." He breathed, face hot and sweaty— stomach coiling with disgust and shame, knowing he's committing such a filthy act, but he can't help himself, not when you're clenching so hard on his cock, forcing your older brother deeper into you. "Fuck, you're tighter than Robin..." He whimpers, desperately rutting into your insides.
"B-big brotherrrr," you mumble, and he bites his lip, realizing you're still asleep. "Shhh, it's okay," he whispers in your ear, folding himself until he's directly pressed into you, tongue circling around your nipple. "Pleaseeee," you pant, encouraging him to rut deeper into your cunt, stretching your 11 year old pussy out. "Be quiet, sweetie. You're just dreaming, okay? You're still asleep." His voice is so soft and warm, and instantly, you relax.
"There, there," Sunday holds you close, saliva sticking to your chest with each flick of his tongue, pushing his cock deeper into your pussy, adoring the velvety sensation of your walls. "Big brother's got you, he'll take care of your cute little cunny." His arms are wrapped around your shoulders, pumping his hips to fuck you into the mattress. "Fuck, I can't get enough of you, sweetie." He says, deciding to rub your clit.
Your brother loves how fragile you are, how limp you are in his arms. You're so tiny compared to him, allowing him to stick his cock into your underage pussy and ragdoll it until you're a quivering mess, but Sunday knows he must stay gentle, continuing to roll his hips and groaning from the sensation of how fucking slick you are. "F-fuck, good girl. I love you, sis. I'm sorry that I'm such a pervert." He leans in to claim your lips, pumping your miniature figure until with a moan, he's spilling his seed deep inside your 11 year old cunt.
Your little legs tremble, whimpering in your sleep, and after a moment or two, Sunday slips out of you, admiring the work he did; your own big brother's cum leaking from your cunny, earning a chuckle from him. "You did great, darling. You'll make a perfect wife. My perfect wife."
What a disgusting pervert.
Sunday tucks himself back into his pants before burying his face between your legs, gliding his tongue over your pussy and teasing it around your clit before meeting your folds, cleaning you out. "You taste divine, sweetie," he says with a grin. "Even if it's my cum mixed in..." He laughed, pinching your clit to hear you gasp. "My little sister and her sweet, sweet cunny. Nobody but me can have a taste of it." He brushes your hair out of your face, seeing how you're still asleep.
A soft smile spreads on his lips as he looks up at you, sticking his tongue deep into your pussy and lapping up his seed like a no good mutt. "My perfect bride," he kisses your clit, licking his lips. Your toes curl from the contact of his tongue exploring your folds, swallowing down every ounce of his cum that spills from your cunt. One day, you'll be so full of it that your stomach would be swollen with his child—
Ah. Fuck.
His cock pulses, pausing before continuing to lap up your cunt, even if he's cleaned it completely. Sunday just can't get enough of it, he swears, you're so fucking delicious and you're all he wants. His precious 11 year old sister, with the tightest cunt imaginable. You're still just a child, and yet he's completely bewitched by you, infatuated with every single thing about you— the way you smell, the way your flesh feels like. Sunday sighs, finally pulling away and readjusting your panties back to your crotch. "I love you." He says in the silence.
Another soft sound leaves you, seeming to smile from his words, and Sunday kisses you again, making you taste yourself. "You're quite the eager little girl, aren't you? Getting all soaked for your older brother." He pushes his head down, sucking on your tits again before cleaning up his saliva with his tongue.
"Goodbye, darling." Footsteps fading.
