-----------------------------------------------------------------------------------------
the Oh family used to be a happy one, y/n had a kind father and mother and a loving brother but.... Things took a turn when s/o's father because abusive towards her mother....
EunSeo was protective of her daughter even as far as obsessed....,She didn't let her daughter have any friends and other than school or family trip Reader isn't allowed to leave the house.To her, y/n was a pure girl, reminding her of herself when she was young and oh how much she wanted to be pure again.... After what her husband did to he
When y/n was just 12 EunSeo started to.... Touch her, "M-Mommy what are you doing?"y/n stare at her mother in confusion as EunSeo start to grope her own daughter, Skinny hands touching small breats through the thin clothe as y/n's big eyes staring into her mother's dull ones, she was scared..."Oh, now now it's ok, mommy love you very much, that why she's doing this ok?"y/n nonly nodded as her mother kept touching her little breasts,it felt weird,nobody ever touch her there before and mommy even said not to let anymore touch her yet here she is,another hand playing with her daughter'a cute pink folds through her pink panties making y/n's thighs tremble to stand still"M-Mommy it feel weird"she would said but It fall to her mommy's deaf ears as she coo at how adorable her daughter is"But it feel nice doesn't it? This will be a secret between us ok? Don't tell anyone or mommy will be sad "
It started simple as that but overtime EunSeo would even finger her own daughter and even kissing her in the bathroom or when the other members arent home,Whenever her daughter refuse or fight back it's quite annoying for EunSeo and this would usually earn y/n a few slaps across the face or getting yell at as her mother kick her harshly in the stomach. Soon y/n learn, she accepted this as mommy's love and make sure to keep her pretty pink lips together
y/n of course didn't told anyone about this because EunSeo told her to keep this a secret because the others might try to seperate her and mommy and she certainly wouldn't want that to happen. Other than mother, Reader was also close to Sangwoo, he was her brother and she loved him with all her heart, even shielding him in one of her father's outburst despite being smaller and more fragile, despite that overtime y/n would try to avoid her own brother because mommy doesn't like it when she's too close to him, this make Sangwoo Angry, perhaps it was because his mother knows how much of a sick man he is and his feelings for his own sister but still, it's not as if she's any better
After her father death, things didn't got better for the Sangwoo nor y/n for now EunSeo would sexually abuse her own daughter in front of her son, beating her and even Sangwoo if he dare step into her business
Once y/n turned 14 things took a turn, she was woken up to a loud scream of her mother through the room, quickly, she went downstairs just too see her own brother sang wood standing over her mother's death bod
EunSeo's cold body lay there as blood oozes out of her chest, it wasn't as horrifying as the man next to it thought, Sangwoo's was covered in blood, his dull eyes stare down in disgust and horror for what he had done, the knife in his hand fall down as he freeze, he couldn't believe what he had done
y/n being terrified of what she's seeing couldn't even scream, as if her throat was sealed shut and her face went pale, she flopped down on the floor making a loud thud that alert Sangwoo of her present.Eyes to eyes,Sangwoo stare at his sister trembling on the ground, slowly he walked up to her Making y/n's heart beat so fast that as if it's trying to break out of her chest "O-Oppa don't, don't,.... " she can't even speak probably, tears flow down her puffy cheeks, she was scared and terrified, this isn't her brother it's the monster who killed her mommy and is going to kill her too
Sangwoo kneeled down infront of his sister, his eyes Looking at her with the same scary look that mother would give her as he Stoke her cheeks gently"Shhhh, it's ok, it's ok, Oppa is just trying to protect you-"He was cut off as y/n Shirnked and whimpers,she felt sick"N-no y-you killed mommy a-and you're going to kill me too! "And Sangwoo only chuckled" silly,oppa would never hurt his adorable sis....unless....she's naughty of course!Now, let's get you back to bed, oppa gotta clean his mess up"With this he tried to pick the small girl up but she only hide away from his touch"N-no,don't touch me!"She was scared and angry as her tears keep falling but this only annoy her brother more, causing him to grab a chunk of her hair and drag her down the dark hall as she scream and cries.
She was dragged down the basement where EunSeo would keep her whenever she's punished and Sangwoo pushed the small girl's body down, making her whimper as her skin come in contact harshly with the dark and rough basement floor"You know, I was planning on letting you rest and taking care of you but honestly, you're getting on my nerves, you were so good for that whore but now disobeying your oppa?"the bloody man walk down slowly, each step making y/n's heart beat faster, is he going to kill her now? Is she going to die here?
She was quickly pulled out of her thoughts as she felt Sangwoo's foot on her head, pressing down slightly as he stare down as her with eyes filled with sick desires "O-Oppa, please stop, it hurt it hurt! I'm sorry! I'm sorry I won't tell anyone i-" she was cut off by a scream comming up her throat, sangwoo slammed his foot down on her head, pressing her pink cheek against the floor, she cry and cry as her small hands grabbed his foot, trying to get it off her head "S-stop, please.... " she let out small hiccups and Sangwoo seem to be.... Enjoying this, he could even feel himself Getting hard from all of this, his cock is already making a tent on his pants but this is what he expect honestly,it isn't the first time he got hard from seeing his adorable little sis being hurt.
Sangwoo was Nutouriust for jerking off in his room with his sister's panties or bra whenever EunSeo abuse her, he would fantasize about the look on her face as mother beat her, his sister begging as tears run down, her bare body filled withe bruises and cuts, gosh it excite him, he know he was sick and that he shouldn't be doing this but he was desperate, he wanted his sister, his own flesh and blood to be his cock sleve, his play thing, his l o v e r
"Stop? oh dear, this is only the beginning I'll make sure to hurt you more than she ever did"with this he take off his foot and squat down to her level and then get on top of her, One arm holing both of hers down and his knee Between her thighs to make sure she wouldn't close those pretty legs
"o-oppa?" she felt disgusting and scared as she saw the look in her brother's eyes, they were lustful and as if we're about to eat her alive.
Slowly, his bloody knife went over her pretty collar bone, over all the bruises and cuts that EunSeo left on her, to him they make her look so so pretty.... It's a shame that it wasn't his marks though, but of course he could change that.The knife cut through his sister thin nightgown, revealing a young youthful body filled with scars and bruises, some were even new,her perky little breats with pink little cherries on top, her clean little cunt that were abused by her own mother make him even more excited, he wanted this for so long and now finally, he can have her.
y/n closed her eyes, trembling and hoping this Would be over soon as she felt a pair of lips pressed down on her own pink ones, the kiss was hungry and passionate, his tongue playing in her mouth, savouring the taste of his own sister, he threw the knife away and his hand started to grope her, making her let out a yelp that was blocked by the kiss he's giving her, his fingers touching and pinching at the cute pink cherry on her breast, feeling the soft skin against his hand making he feel like he's in heaven, he was a sick man, he can't go back anymore, he's too far gone.As he let go of her lips a string of saliva connecting their lips broke and Both were breathing heavily, Sangwhoo who melt into the kiss and y/n who only felt fear.
"I love you y/n, I love you so so much and now, you can love me too" he said as his nose creep into the crook of her neck, licking and hitting down on the soft skin, savoring the taste and scent of his own sister, she was young yet he knew she'll be a slut who beg for his cock soon, he just need to train her properly. his lips slowly moved down to her collarbone, giving it kisses and sucking on her skin, leaving some bruises behind as the small girl moans, she felt ashamed of herself for feeling good but she can't help it,the sensation make her cunny wet and nipples hard, it doesn't help that her brother is sucking on them hungryly, his Bulge rubbing against her belly. after a while, he let go, pooling his sweatpants and boxers down he reveals his already hard cock, it was veiny and thick, about 8 inches and already had some pre cum on the pink tip.
The poor girl was shaking and the blood from her face ran out as she saw ther oppa's giant cock"I-It won't fit!please no!"she cries and beg but Sangwoo only ignore them and Rub his cock agaisnt her entrance, she tried to close her legs but his strong arms pulled themy wide open, giving him a view of his sis's with cunt "You know, I was planning On streaching you out with my fingers first but since you were being naughty I guess I gotta teach you a lessons now"And with that, he forced his entire cock inside her virgin hole, making her let out a blood curling scream, her toes curled up and her tears flow even faster as her weak hands tried to push Him off helplessly, he groaned as he felt the tip of his cock against her cervix, her walls was so tight and warm and he can even feel the blood dripping out, he was so happy, he took his sister's virginity! EunSeo only finger or eat her daughter out but never penetrated her so for her to feel something this big inside her hurt do damn bad, she begged him to stop, to pull out already but he didn't care.
His thrusts was fast and chaotic, he was like an animal, pulling out until he could almost see the tip of his cock and thurst back in with a force that de finally bruise his sister's cunt, her juice And blood lubing his hard cock as it rape her cute cunny "God! You feel so damn good y/n! I'll breed you, I'll breed my little fucking sister and make her by whore!" She didn't want to hear those foul words, they make her feel dirty she hated it but the pain and pleasure was too much, she can try help but moan and as his thursts got faster her wall cleanched onto his cock, milking it as cum fill her womb. sangwoo pulled out, causing a flow of semen blood and juice leak out of his sister's abused hole, she was sobbing, this is horrible, she didn't want this Yet.....
"sweet dreams" with that, he tucked his cock back in his pants and gave her a soft kiss on the forehead, he look at her ruinee body one last time before walking out, shutting the basement door and seal her from any light.y/n only curled up into a ball, feeling cum dripping out of her as she sob on the cold floor..... "mommy..... Save me..... Please.... "........
