"channie?" you whisper softly, tugging the comforter down to reveal even a sliver of his face. his breathing is shallower than usual, and he's still, but you were unsure if he's already drifted off to sleep. he never sleeps early. at least not when he's staying the night at your parents house. you repeat his name, but silence greets you, and you can't help the disappointment in your stomach. you sigh, reluctant to walk away and surrender to sleep. you lingered for a minute longer in his room, still hovering over him, too scared to turn around and leave. the walk to your room was long and dark. you mustered up all your courage just to run down here, and you don't know if you can make yourself do it again.

this was all your fault. you had a scary dream, and it was hard laying in your big room all alone with nothing but your thoughts to torture you. you feel like a kid again, close to the brink of tears, thinking of facing this fear. It's always been better for you to let sungchan face it for you. that's what big brothers are for! you would rather snuggle up in his bed and cling to his arms wrapped around your waist like he was a border to shield you. even if sungchan teased you for still getting scared this easily, you know you could count on your big brother to protect you. but he can't protect you when he's sleeping.

you reach out and push on his shoulder outside the cover one last time. when he stirs a bit at the touch, you call out for him again, “channie... I need you.” this time, you see his eyelashes flutter, his eyes squinting as he peers at you. not even turning to look at the time on his phone, he just lifts his cover, looking back to you standing pitifully with your lip tutted out. “you okay? scary dream?" you take his actions as a gesture to slip into the bed with him. climbing to the side closest to the wall and lying directly in his arms, he drops the cover on both of you.

"mhm, had a bad dream," you finally respond, closing your eyes at this newfound warmth. he leans forward, kissing your forehead, words rumbling against your back. "I'm sorry, baby. I have you now." you smile at his words, feeling so safe and content.

a lot of people say your relationship with sungchan is weird but you never understood.

this was just sister-brotherly love. sungchan knew you better than any person ever has, even your mom. since your mom married his dad, you were forced into this new lifestyle with a new sibling with a very different personality from yours. It was hard at first, but you and sungchan clicked, and you never hid who you were with him and he never hid from you. sure he made your guy friends and boyfriends uncomfortable but they're just weird. there was nothing weird if you liked the affection and attention from your brother. the hugs, holding hands, occasional kisses on your forehead, and especially cuddling. he's your favorite guy! told you over and over again how happy he was that you were his sister, that you were the best little sister, and that he loved you more than mom and dad.

sungchan's hands roamed your hips, tugging you closer, and you let him in. his room smells of vanilla like him, and you don't think about how it has you falling deeper into him. too distracted by the goodness you feel, you don't think about the weird feeling filling your tummy when he presses himself against you, firm and hard behind you. barely thinking about how much bigger and stronger he's gotten and how he's grown into your type. you stay like this for thirty minutes and almost think sungchan had fallen asleep. but after a while, his hands slowly smooth down your stomach until he's pressing on your panties.

you gasp, turning to look at him, but he's already staring at you, big hand pressing against your mouth. "shhh... just let me." you can't comprehend what's going on. he's way too strong for you to fight back properly. "you make me so hard, baby," sungchan groans, pushing his hips to rut against you. "so sexy.. my little sister is so sexy,"

the tears in your eyes have already started flowing down onto his hand. you're confused and conflicted with what happened to make sungchan have such a direct change. you hate that your pussy clenches when he works his fingers inside your panties, fingers dragging against your folds. he circles your clit, and you feel heat rush through you for the first time. your body is trembling and tears are nonstop. "baby— baby, you have to calm down—" sungchan's voice is deep and dripping with concern, but you don't know how to calm your body.

"you know I won't hurt you," he whispers, "your big brother loves you." but you can't listen. your hips are bucking up into his hand, and you feel icky. his hand falls from your mouth, and everything breaks loose. "this– this is wr–wrong, channie," you sob. "we're not supposed to do this."

Instead of answering, sungchan kisses you, tongue running messily over your lips, and when he intrudes your mouth, it all feels so foreign. you don't know how to react, just letting him abuse your mouth until your lips are bitten red and swollen. the kiss slows your thinking down, your legs clenched around sungchan's hand tight, and your eyes rolling back. when he pulls away, spit trails, and his fingers start circling your clit again. "see baby," he huffed out, forcing your legs to spread, "not that bad, huh?" you sniffle and pout, pushing back against him subconsciously.

"channie—" "call me daddy." it was phrased so softly that if it wasn't so lewd, it could be ignored. and it should terrify you. It should be grossing you out to be this close to someone you grew up with, especially someone you thought was your real brother, but your tongue hangs out like a puppy for him anyway. like you're giving yourself away. his mouth drops open ever so slightly as his eyes follow the motion of your tongue, and then he lets out a low hum. "say it."

"sungchan..." you pause when he gives you a look, finger prodding your hole. you start wiggling again. "not there daddy... please... know we can't!" your lip tuts out, fingers digging into his arm in an attempt to distance you two. "don't worry, baby daddy's gonna make you feel good, don't you love me?" his question comes out as more of a statement like he doesn't doubt that you do love him. "I love you, daddy! I–I do, but–" sungchan scoffs at you, pulling your panties down to your knees, and the stickiness makes you shy. you gasp, covering your mouth with both hands, when something odd presses against your pussy.

"never done this before?" you shake your head no, hips seemingly rocking on their own. "never felt this before... don't—don't think we're supposed to do this, daddy..." when the words leave your mouth for a third time sungchan comes to a halt. "I love you. you're my little sister, and I'm supposed to show you these things." his breath against your skin makes you shudder, goosebumps popping out all over your skin. he kisses down your neck, sloppy and slowly till hes pressing kisses on your shoulder. "I won't put it in."

you don't understand what he means until he's dragging his cock between your slit, collecting your slick to use as a lubricant, and instead of going inside, he's spreading it. your vision nearly blanks feeling him on your pussy. he's so hard and heavy, and your cunny is aching the slower he pushes his hips forward and slides his cock on you. "fuck... baby, you feel so good for me." he works to circle his tip on your clit, feeling you writhe under him.

"nnng daddy daddy daddy!" you whimper. this is so embarrassing. your pussy is clenching and pushing out more wetness, and you feel like you'd rather die than let sungchan know how sensitive you are. your nipples are hard poking your shirt, and when he uses his hand to push his fat tip so deep inside your lips you can't help but curl and wiggle. "please—" "yeah? big brother making you feel good?" you swallow and try to talk, but he instead slides between your folds deeper and the words get trapped in your throat. you can’t handle having him like this. It was too hard to even look at him. "feel—feel you—" he nodded, his cold hand planting itself on your cheek, fingers dipping to wrap around your throat. "I know, baby. can feel me in you." the air was thick between you two, getting even more tense when you tried to push his hand away in panic. "n–no! no no daddy–" your mind is bleary, voice breaking.

theres this strange shift in his demeanor when he looks into your eyes. not unexpected, just more— intense. when you blink back tears and sniffle, it's almost like his face hardens. eyes flickering over your expression, lingering on your swollen lips again before it drops down between your legs. It's like he’s got more to say or something left to do. you whimper the longer he continues to put pressure on your throat and pull on his wrist a little. "d—daddy— gonna—gonna cum...!"

"I'm so sorry, baby. I need to feel you," he said, closing the gap between you and lining up at your entrance. he finally sank his tip into your needy little hole, his lips barely grazing yours. you feel weird again. not being able to stop your eyes from fluttering shut when he stretches you out. your mouth is open and wide from the painful sensation filling you as he starts slowly thrusting, sliding deeper with each thrust until he bottoms out. "no! no sungchan—” you try to warn, but he tightens his grip to silence you, and your body starts to feel like it's breaking down.

the pace he sets is menacing, enough to have you whining and arching your back into him. the tip of his cock is nudging your cervix with every deep thrust. you can't hear him cooing anymore, just the sounds coming from your bodies meeting. “oh no... did I lose you, baby?" he whispers in your ear, letting go of your throat so you can breathe. your heart is fast hammering against your chest as he fucks you into your very first orgasm. "close for me, baby?" you nodded, tears spilling again. "hurts—feel—feel big brother in—in my tummy..."

sungchan's hands slid down your stomach, firm hand pushing your abdomen as he bruised your pussy. "mhm?" your brother smiled, "feel me here" your words are incoherent when you start twitching against him. "come on. cum for me, baby. cum for your big brother." you shook your head, clouded and lost in thought as you pushed your hips to meet his sharp thrusts. "gonna fill this pussy up," that’s all you need to make your walls clench even tighter, pulsating with the euphoric shocks of your orgasm. Your moans are high-pitched, and you repeatedly hear weak mumbles of his name.

“there you go, get me all messy, baby.” he praises, leaning forward to press a long kiss to your forehead. "my favorite little sister.”
