-------

the night started innocently enough, indulging in a few celebratory drinks with your big sister. you hadn't seen each other in a while so you both were nestled up on the couch together, spending a night in at her apartment to catch up for your 21st birthday.

after awhile, things started to get fuzzy for you. youd gone a little overboard with the drinks. were you on your 4th drink. your 5th? you didnt know. you just leaned against your sister, using her as an anchor. you felt a pang in your bladder, finally realizing how badly you had to go.

you go to get up to head to the bathroom, but your not quite as tipsy sister pulls you onto her lap. you swear you feel a pulse underneath your butt, but you ignore it. giggling and pushing against her playfully. you slur out that you need to go, so she'd better ease up on your tummy.

she chuckles cruelly and hugs you tight with her arms around your waist, forcing a whimper out of your mouth as she constricts your poor bladder. you huff and slur that you'd had enough, pressing against her a little more forcefully. she furled a hand into a fist, pressing it roughly into your bladder and using her other arm to flip you over, rolling on top of you

you cry out as she rolls over, the weight and pressure causing a little piss to dribble out of you into your underwear. you gain control again and wriggle against your sister, who's now grinding against your ass. you finally process what the pulsing under you was as she grinds her hard cock against you.

you whimper that this is wrong, begging her to stop. that only seems to provoke her further as she yanks your pants down. she keeps her hand on the back of your neck, sitting up momentarily. you can't quite tell what shes doing till she spreads your ass cheeks and you feel a cold, slimy liquid dribble onto your exposed hole.

you cry out and struggle under her futilely as the lube drools down over your front hole too. she lays down on you and starts blindly thrusting against you, putting a hand on your mouth and the other clamped around your neck. as soon as her tip finds your ass, she drives her full length into you hard.

you let out a stifled scream into her hand as she pumps in and out of you, moaning loud as she fucks your ass hard. you tuckered yourself out quick, too drunk to fight against her anymore. you stifle moans, biting your lips as she pounds into you.

after a while you feel her thrust more desperately, wildly pumping in and out of you. she pulled out all the way unintentionally and her cock slid downward, aiming right at your now soaked cunt. she slammed back in, impaling your virgin cunt. you squeal and your bladder gives out as she starts raping your front hole, squirting pee onto the conveniently placed blanket.

not that it'd do much to prevent 5 drinks worth soaking through to the cushions. she groans, the warmth driving her nuts as she slams hard into you a few more times. her cock stiffens and sprays rope after rope of cum into you, right against your now bruised cervix as you drench her and yourself with pee.

she collapses against you, huffing and puffing as her cock pulses inside of you. she sighs contently as she finishes filling your hole with her cum, pulling out and leaving you limp and whimpering quietly on the coach. she plays with your stretched holes a little before covering you with a blanket and shutting off the living room lights.

leaving you to drift off to sleep, filled with your big sisters cum.

I love when guys fuck like dogs, delirious little humps and whines, they're so pathetic~

Especially when their eyes roll back as you refuse to take their cock ring off until they make you cum

[petitepixiegirl]

I love sitting under big brothers desk while he plays games! I love nuzzling my face against him n being his cute little sister, but sometimes he gets mad at his game and is really mean to me >_< He pushes my face into his shorts and tells me good little sisters help relieve their older brothers frustrations, rubbing his big cock all over my face and squeezing my jaw until I open my mouth and forcing the entire thing in. He doesn't even care if I gag or cry, he just keeps on fucking my face until I'm a drooling mess n eventually I feel his dick twitch and something warm n sticky is pumped down my throat, telling me that's what happens when big brothers really love their little sisters, but it has to be our secret or he won't let me watch him play anymore :{

big brother who knows his cock won’t fit in his little sisters cunt but he tries anyway over and over again <3

Blackmailed by my brother. He starts using everything he has against me. Forcing me to suck his cock, making me show him my tits in the bathroom at school. Eventually he’s bored and pushes me further. He bends me over and grinds into me, gets me used to the feeling. Until he finally “accidentally” slips in one day, taking my virginity. He fucks me deep and hard, pumping me full of his cum while he plays with my nipples. The next day he forces me to cum on his cock, telling me that if I didn’t like it I wouldn’t have cum.

I’m his little personal slut dump now.

[angelc3st]

big bro protecting you from all the guys at school, not because he doesn’t want your heart to get broken, but because he’s the only one allowed to fuck your tight little pussy

[pinkiepawz]

big brother that holds me down and apologizes the whole time he uses me <33

[motherlyslut]

I pretend to put up a fight when big brother gropes me and lifts up my skirt during school but he knows when we get home I'll be on my knees begging for his cock.

Rape doesn't have to be hateful, it can be some kind of a lovesick crazy dude that's in love with his little sister and rapes her so hard she cries while holding her wrists and whispering he's sorry and that he loves her.

Okay that's what I need now I'm in the mood for soft cnc incest stuff for a week now, send me asks about it please 🙏🧎‍♀️

[driven-feral]

Big bro running into his lil sis at a party, both drunk and high. He decides to stay with her to protect her. Their friends tease them and tell them to dance together.

The occasional grind against him from lil sis makes them laugh. Until it starts happening more and more often, for longer and longer, being more and more intimate. Big bro's hand finds its way to her waist, keeping her close. Lil sis puts her hands on his chest. She grinds against him yet again, this time his thigh, but comes back up blushing, and a slight moan escapes her lips.

Their friend's attention has thankfully gone to something else right now, as his hand moves down to grope her, pushing her to grind against him, the other one cupping her chin, helping her look up at him while he kisses her. Lil sis kisses back eagerly. He wakes up in her bed.

hanging out with big brother and he casually asks me if I've ever seen a real man's cock before, and ofc I giggle and say no, such a silly question!! Before I know it he's standing over me unzipping his pants and pulling out his thick throbbing cock so close to my face I can smell it.

older brother who teaches you how to ride a bike and how to ride his cock <3

Megumi did not know whether or not to be angry with you or himself. Maybe a mixture of both— no. No, you. Your fault. 

Very rarely did he have time off from missions. Often, it was back to back assignments in far away places. It had been two or three years since he had seen you last. He went back to your apartment as soon as he came back from an especially lengthy mission, only to find it empty. No furniture, no clutter. No little sister in sight. 

He found your landlord. Some old sleaze, Megumi remembered him well from when he helped you with moving in. He was so angry that day, extra eyerolls and teeth gritting. He never wanted you to be anywhere that wasn't attached to his hip. You weren't meant to be on your own, you needed him to protect you, but you insisted on a little independence. 

"She hasn't lived here for a while, son" the landlord answered, leaning on the frame of his front door, arms crossed. "Said she was moving into college dorms."

College? What did you need college for? To get some degree? A worthless slip of paper to show the four years that you wasted? 

Megumi stomped away from the apartment complex with a look of pure betrayal. 

He'd been sending you money and clothes— anything he could use to keep you entertained while he was gone— over the years. Was that not enough? If you were that damn bored, you could have told him. Megumi would have done something, anything, to keep you stuck safely at home, but no. You weren't at home. 

Were you even alive, he wondered? He had heard stories of those college bastards eating freshman girls alive. Sororities hazing sweet things like you to no end, fuck boys slipping mystery pills into drinks of girls stupid enough not to watch them, and God knew you were just that stupid. What if you got knocked up by some awful frat guy while Megumi was gone? What if you were slutting around campus? Or worse:

What if you had gotten a boyfriend?

Classes here were much harder than you had anticipated. You knew college was a big deal. You hadn't done especially well in high school, either, but the social aspect of college spoke to you so loudly. The movies had hyped it up well. You wanted it all— a spot in a fancy sorority, maybe Chi Omega or Kappa Alpha Theta. You wanted a clique of close girlfriends to gossip with. You wanted to sit in the front row of every class and answer every professor's questions with precision and accuracy. You wanted to be a cheerleader, a book worm, a prodigy, and a notorious knock-out all rolled into one.

Well, year one of college and you were severely disappointed.

You went bidless with every sorority you tried to rush. Friends were hard to keep and come by— your roommate never even spared you a side glance. She was too busy bringing boys home to catch your name, you assumed. You sat in the flooded middle rows in your lecture halls, and the only question you had ever answered correctly was when your physics professor aimlessly asked what day of the week it was.

Your essays were consistently given static, mediocre grades. Your exam scores were less than stellar. The cafeteria's food was tasteless and bland. Your feet constantly hurt from walking around campus all day. Your schedule was awkward and poorly spaced out.

You didn't know why you even left home. Not your old apartment, but home. Home with 'Gumi. Sure, you didn't see him a lot, but if your brother was your only shot at a decent human connection, you'd take seeing him once or twice a month.

You were petty to move out in the first place. You wished you could smack your old self right across her stupid, stupid face! You wish you could shake her by the shoulders and say 'stay home! you aren't cut out for this!'

Who were you joking, thinking you could make it on your own? You weren't very smart, and as much as 'Gumi loved you, he made that very clear.

"You're a girl," he often told you when you were both small children. Some neighborhood boys picked on you, calling you creative names like 'stupid' and 'idiot,' articulated as children do. "Girls aren't supposed to be strong or smart. That's why they have brothers to protect them," he would reason, his logic going unchecked by anyone around him.

"You're a girl," he'd say when you both got a little older. Some boy had played with your hearts, stringing you on. "Guys like hurting girl's feelings. That's why you don't need one." He wanted badly to add, 'you just need me,' to that sentence.

"You don't need to work, you know," he told you after you finally finished high school. "Just stay with me. You don't need to do anything else."

God, you wish you had listened to him. Instead, you had your nose stuck up so high in the air that you would drown if it rained. You left home because you wanted more for yourself, but was this the universe's way of showing you that you had all you needed? You left because you thought you were big and bad, because you thought you were a woman. Well, life was certainly humbling you, because just like Megumi had always told you, you were just a girl. 

A girl sitting in a tiny, cramped dorm room with a dirty nightstand, awful grades, no friends, no place to belong, and no romance. The high hopes you had in the beginning of the semester had plummeted. All you wanted was your older brother. 

After high school, Megumi's overprotectiveness and thinly veiled old fashioned way of thinking was suffocating. You brushed off his words with pouts and huffs. He was right, though. He was always right. You did need him to protect you, to provide for you. 

You needed Megumi to save you from your own stupid choice, and quick.

Finding you was surprisingly easy. There were only a few local colleges. Megumi was certain you weren't anywhere across the country, or God forbid, international. After a little digging, who found that you were attending a community college only ten or so miles away from his house. High acceptance rates, low reputation, and zero tuition. Made sense. 

He scoffed at the idea. How could you go somewhere so lowbrow? He didn't want you enrolled back in school, point-blank, but if you had to go, he would've paid to get you into somewhere much better. He wanted the best for you. This place was not it. 

Hands crossed over his chest, shoulders slouched, Megumi stared at the brick walls of your dorm building. It was old and dilapidated. He was sure the admin board would refer to it as 'rustic' or 'charming,' but really, it was a dump. No place for his baby. Baby sister, he meant, not... not that way, right?

Megumi shook his head, trying to dispel the thought before it could settle. Of course, not that way. He was just protective. You were his sister, and this place was beneath you. It wasn’t about control, it was about making sure you were safe and comfortable. That’s what older brothers did—looked out for their family. He had every right to check on you.

He didn't want to control you. He just wanted you to do what he told you to and to follow his guidance.

Still, standing there in front of your dorm, something gnawed at him. A small voice in the back of his mind whispered that maybe, just maybe, he wasn’t doing this purely out of brotherly concern. He brushed it aside, pushing his hands into his pockets as he glanced up at the windows. One of those was yours, no doubt. He hadn't been able to find the exact dorm number, but the building wasn't very big. A perk, in this case, of the budget college you'd stuck yourself in. 

Megumi sighed, his frustration growing as he scanned the windows. It wasn’t supposed to be like this. You weren’t supposed to be in this kind of place. You had him, and took care of everything for you. Sure, maybe he wasn't physically around often. Maybe he couldn't give you his time, but he gave you everything else. Every card in his name was free for your use. Every cent in his account had your name written all over it, had you have wanted it.

Women are ungrateful, he reminded himself, shaking his head in frustration. It's just how they are.

He turned the corner, making his way toward the entrance, rehearsing what he might say. He wasn’t here to pick a fight. This was just a pick-up. A chance to remind you that you didn’t have to settle for something so mediocre. A chance to bring you back home, where you belonged. His chest tightened as he stepped inside the building. 

The hallway was humid and dimly lit, the faint hum of old fluorescent lights filling the silence. As he approached the stairwell, his footfalls echoed—louder than he appreciated in the still quietness. He didn’t know which room was yours, but he had a feeling he’d know it when he saw it.

Reaching the second floor, he paused in front of a row of doors. His hand hovered for a moment before he forced himself to knock on the one closest to him. He had no plan for what he’d say if this was the wrong room or worse, if you didn’t want to see him ever again. The uncertainty didn’t matter. He’d bring you with him no matter what. 

He wasn’t leaving until you understood that this—this place, this whole plan—wasn’t what was best for you. He’d make you see that you still needed him, even if it meant dragging you out by your wrist like a child. Shoving aside whatever was stirring in the pit of his stomach, an unsettling mix of guilt and something else, he watched the door creak open slightly.

Your puffy, flushed face peeked through the door. Damn it, crying already?

"You don't get to be mad at me," you sobbed angrily. 

This is why Megumi still saw you as a something to be protected. A weak, emotional woman. 

"You left me first! You left and I never knew when you would come back, 'Gumi—" you shook your head, burying your face back into the pillow under you as you corrected yourself, "—Megumi."

Perched behind you, pressing his clothed erection against your ass, Megumi huffed. His chest planted against your back to trap you against your thin, uncomfortable mattress. 

"That's different. I have to work."

You sniffled and felt more tears slip from your eyes. Small stains were starting to cover your pillow. Wet splotches giving away your cries of anger, sadness, and pleasure. 

Megumi’s sigh was heavy, his breath brushing against the back of your neck as he leaned in closer. “You know it’s not the same,” he said, his voice calm, almost patronizing. His arms caged you in, keeping you pinned beneath him, as if he could physically restrain your defiance. "I don’t have a choice. You do. You chose this." His words were measured, but there was a subtle edge to them, the weight of his snark pressing down as much as his body was.

You squirmed beneath him, trying to shift your weight, to pull away from the suffocating feeling of his presence. But he didn’t budge. He never did. "You say it like it’s so easy," you said, your voice cracking with every word. "But you don’t understand. You don't know what it's like to feel so lonely. 'S like you don't love me anymore, 'Gumi, like I'm not important."

Megumi's grip tightened slightly, his chest rising and falling against your back. His voice softened, but the meaning in it remained. "I’m making sure you’re taken care of. That you don’t end up in places likethis." He tipped his head back, gesturing to the disorganized dorm room, even though you couldn't see what he was doing. "Do you know what could happen to you out here? Here where anyone could take you? Hurt you?"

You felt his hands snatch you up by your hips. A more freeing position, sure, but more exposing too. Your ass perched in the air and your face was pushed further into your pillow. 

"I’m the one who's always been there for you, you know that. I always take care of you." 

Cool air whooshed over your bottom. Megumi's palms ran over your cheeks. You could've sworn you heard him groan at the sight before him. Your cunt sticky and spread, nearly as wet as your tears. 

"Don't ever say," he spoke between placing firm licks over your clit from behind, "that I don't love you."

He spat on the little nub, slicking you up. From broad strokes to pointed swirls against the tip of your clit, Megumi felt himself growing lost in you. He'd wanted this for so long, he just didn't know it. He didn't know why he wanted to so close to you, why he felt the primal need to protect you, but it all made sense now.

One protects their property, don't they? They get a guard dog to chain up at the edge of it. They keep watch, armed on their porch, ready to shoot anything that moves.

A foreign feeling entered you. A snaking tongue slurped at your hole, wriggling deep inside and toying with your tight walls. 

"'Gumi, no," you couldn't fight it. Embarrassed as you were, you wanted— needed, to cum.

Fingers replaced the intruding tongue. The angle was all too good. Too perfect. You felt drool prick the corner of your mouth and heat rise through your lower body. It was like a wire wrapped around your womb and cinched, tighter, tighter, tighter—

"Awh! No, no more," you cried out. "Can't take anymore!"

"No?" Megumi looked almost amused. "Still sensitive, huh? Guess no guys have broken you in yet."

You shook your head slowly.

"Good. We'll fix that, then. At home."

Thanks for requesting <3

big brother!Sirius + little sister!reader ♡ 996 words

When you hear the door to your dorm open, you assume it’s one of your roommates or Regulus coming to shame you for missing dinner, but then your mattress shifts with the weight of someone else sitting down and a familiar teasing voice says, “If you’re dead under there, everyone’s going to think it was me.” 

You peep your eyes out from under the covers. “How did you get in here?” 

Sirius isn’t even looking at you. He’s making himself comfortable at the end of your bed, both legs crossed under him and hair falling in his face as he unwraps dishes and utensils. 

“Reggie let me in. He seemed to think you might need some company.” 

“He’s such a narc,” you grumble. 

Your brother only snickers. “Sit up, I brought you dinner.” 

You’d much rather stay under the covers, but know Sirius would only wrestle you into an upright position anyway. He always gets his way. 

“Yikes.” He makes a face as you sit up, revealing your bedhead and swollen eyes. “You’re having a rough one, huh?” 

“Shut up.” You glower at him and take the plate. “It’s not that bad.” 

Despite your grumbling, a bit of vulnerability sneaks into your tone. Sirius softens.

“No, it’s not,” he agrees, reaching forward to brush a piece of hair away from your face. “We’re always pretty; it’s in the genes.” 

You can’t help the small smile that fights its way onto your face. This is exactly the sort of thing your older brother would say when Regulus was twelve and sulking over getting his first pimple or when you nearly broke down in tears trying to style your hair. Despite his tomfoolery and general ridiculousness, Sirius’ levity actually provided a voice of reason in your family, reminding his siblings and cousins that things weren’t always so dire. 

“Thanks for bringing dinner,” you say.

“No problem,” Sirius replies softly, as though worried his gentle tone will be overhead and his rapscallion’s repute thusly destroyed. “Is it good enough that you’ll tell me what’s gotten you so upset?”

You blink at him in surprise. “Reg didn’t say?” 

Sirius’ mouth twists, dissatisfied. “He didn’t. I guess I would’ve been more likely to find out if I’d just pretended I already knew, huh?” 

That makes you chuckle. “Probably, yeah.” 

“Well, come on. Now you’ve gotta tell me.” 

You feel your shoulders hunch inwards. “Do I really have to?”

“Yes.” Your brother’s voice is firm, but his eyes are hopeful. 

You want to tell him, you find. You don’t suppose any harm can come from it now. 

You eye him carefully. “I broke up with my boyfriend.” 

Sirius’ eyes pop. He nearly topples your plate leaning forward, like you’re back in your childhood beds trading secrets. “You were dating someone?” 

“I was.” You can’t quite look at him, focussing on cutting your meal into small bites. “Or I thought I was. It doesn’t matter. I’m definitely not now.” 

“Wha—how did I not know about this?” 

“Because obviously I’m not going to talk about my dating life with my brother,” you huff a laugh down into your lap, and you swear you can feel the force of Sirius’ eye roll burning into the top of your head. “No one really knew. He wanted to keep it private.” 

Sirius tilts his head, slotting a piece of his hair behind his ear. “Private in an avoid-the-gossip-mill way or private in a dirty-secret way?” 

You close your eyes, shame curdling in your gut. Even your idiot brother knows enough to be suspicious of something like that. Maybe if you’d told him all those weeks ago, you wouldn’t be where you are now.

“In the second way,” you admit in a whisper. “I, um, sort of assumed it was because of the first, and I liked the idea of keeping things private too, but it turned out he had other reasons.” 

You try to take another bite of food, but it feels soggy and unappetizing in your mouth. You set your plate aside. 

“What happened?” Sirius asks. 

Your face feels miserably hot. “He just didn’t like me as much as I liked him. He didn’t want his friends to know.” Tears burn in your eyes, and when you try to speak again they show up in your voice, too. “I feel really stupid.” 

“Oh, sweetheart.” Sirius sits up on his knees, bending over you to fold you into a hug. His hand presses reassuringly between your shoulder blades, and you let out a little sob. “That doesn’t make you stupid, it only makes him a prat.”

You hug him tightly. “I just feel so silly being upset when he probably doesn’t even care.” 

“You are being silly,” he chastises, but there’s fondness in your brother’s tone. “Of course he cares. He may not be regretting things right now, but I’d bet ten galleons he will be by the end of the month. Trust me, babe, boys are idiots. We don’t know how to act, we almost never know what we want, and we’re ten times more likely to fuck something up if it’s important to us. Just ask Remus.” 

Your laugh is a soggy thing. Sirius rubs your back encouragingly. 

“So, what’s the sod’s name?” 

“Oh, no way.” You laugh even harder, pulling out of the hug to wipe under your eyes. “I’m not telling you.” 

“What?” Sirius throws up his hands. “But we were doing so well!” 

“I’ve handled it, Sirius. I don’t want you to go and turn his skin green or make him sprout nose hairs down to his chin.” 

A giddy grin. “That’s actually not a bad idea. Does Regulus know who it is?” 

You fix him with your sternest stare. Most other people would soil their pants, but because he’s your older brother, Sirius only raises a brow. “If he did, he wouldn’t tell you.” 

“That’s alright.” He steals a roll off your plate, biting into it insouciantly. “I’ll find out.”
