#But when I bring up why I don't like incest suddenly that's too much... OK sure

[mako-island-moon-pool]

Thinking about the time r/ao3 got recommended to me on my homepage and it was a post asking 'what do you do when you're surprised by incest in a fic because it wasn't tagged' (paraphrased) and I commented basically 'I leave, since I was SA'ed by my sister incest really upsets me which makes finding platonic fics for [list of fandoms] a bit difficult' and a mod deleted it then DM'ed me that my comment was 'too heavy' for the subreddit (on a post ABOUT INCEST) meanwhile the rest of the comments were full of people gushing over how hot incest is...

SUMMARY: after what you had thought was a settlement between you and your step brother that you'll only have each other, you were aghast to see him bringing someone into your house, so you had to teach him a lesson for breaking your promises.

AUTHOR'S NOTE: this is a part 2 to "stepbrother's comfort", but in a more twisted way ig? please tell me if i missed anything in the warnings. also, please leave if you are uncomfortable.

"i will always be here for you, puppy,"

"i will always protect you, my love,"

"i only belong to you~"

"i love you"

you're all too familiar with these phrases coming from your stepbrother. you recalled how sweet and caring he was to you from the moment you entered his life until you experienced your first heartbreak. he imprinted on your mind that you are his property, that you belong to no one but him, so why is he suddenly bringing a boyfriend into your home?

were you not enough for him? can you not satisfy him anymore? a train of thoughts came crashing down your mind that you didn't notice the worried gaze of your parents to you, who have been trying to get your attention for quite a moment now.

"—n], [y/n], [y/n]!" your mother yelled, her face troubled. this drew everyone's attention, and they all stared at your dazed figure, worried for you.

"h-huh?" you replied, looking like a deer caught in the headlights as you try to collect yourself and your dark thoughts to act normal in front of them.

"you're quite out of yourself, dear, are you ok?" she asked you, placing a hand as she did so.

"y-yeah, mom, just having a bad day. that's all," you lied through your teeth, softly sending them a smile, "i don't want to ruin the mood here, i think i'll just go to my room,"

and by that, you went to you and jungwoo's shared bedroom after getting an assurance from everyone in the room.

"take good care of my brother, lucas. i hope your relationship lasts," you fakely wished as you sent them a forced smile. "i-i w-will!" lucas exclaimed, intimidated by your towering figure. "good," you said as you continued your walk to the bedroom.

"i'll show you who you belong to, hyung. i don't care if i'm as sick and twisted as you. you were mine and i am yours. no one will ever change that~" you chuckled while thinking this to yourself, planning what you'll do to your lovely stepbrother for the night.

—

the door of your bedroom creaked open, signalling the entrance of your stepbrother from what was happening downstairs earlier. he immediately went next to what he thought was your sleeping figure to check on you if you were ok, after all, he wouldn't let his favorite pup feel bad.

how dare he. how dare he still claim you as his after his shameless actions.

jungwoo was about to pat you when you suddenly pinned him under you. you looked at jungwoo's orbs with bloodshot eyes, brims having tears flow down from them.

"do you know how much i hated every single moment earlier ever since you brought your boyfriend here, hyung?" you sparked up, hurt.

"do you know how much it hurts me that you have others satisfying you when i'm right here? do you know how long i'm trying to control myself from beating the shit out of that lucas, huh?!" you continued to inquire about your step brother who's still recovering from shock from your actions.

"look— puppy—" he tried explaining but you were quick to cut him off with a slap.

"stop calling me that, you filth. am i not enough for you? does he kiss you better than me? is his dick bigger than mine?! if not, why?!" tears stream down your cheeks, eyes flaring up with anger and jealousy from the betrayal that jungwoo did.

"i'll show you that i'm not just your "dear pet", hyung. let's see who's name you'll be screaming by the dawn," you threatened, and with that, you started kissing your step brother hungrily.

jungwoo kissed back immediately as he tried to gain the dominance, but to no avail, your desperation for him has seemed to give you all the strength to put his naughty tongue to submit.

you pulled out from the kiss and instantly attacked his neck to litter it with marks and kisses.

"a-ah— right there, [y/n]! fuck~!" jungwoo moaned from you, sucking a sweet spot on his neck.

"moan for me, you bitch. our walls are pretty thick, let me hear you scream my name in pleasure," you degraded him. to say that jungwoo was surprised with how you've become is a complete understatement, he has never seen you this aggressive and dominant considering that you're always under his control, this got him thinking that he was successful in molding you to be his, and he is liking every single moment of it.

after putting your marks all over his jawline and neck, you forcefully ripped off his shirt and began leaving a trail of hickeys everywhere your lips landed on. jungwoo, in the meantime, was already moaning for you.

"fuck~ you really are enjoying this, hyung~ does he ever make you feel like this?" you taunted, mocking his own words back then.

jungwoo released an incoherent response, impatient for you to already touch him. his submissive state did numbers to your head and immediately yanked his sweatpants away.

you began placing butterfly kisses on his inner thighs, down to his ass cheeks, giving a ticklish sensation to jungwoo.

"ah~ ah~ j-just touch me, [y/n], please!" he begged pathetically.

"tsk. such an impatient hyung. but since you asked so nicely~ i'll give it to you," you purred against his hole, your breath sending a shiver down his spine.

and with that, you proceeded to eat him up, ravaging his insides with your tongue as he loudly squealed like a bitch from the feeling. your tongue went in and out of him as you swirled it around his, desperately clenching, fuckhole. the wetness and warmness of jungwoo has made your cock hard in excitement, completely aroused and desirous of already entering him.

jungwoo came not long after. the great feeling of your tongue has sent his cum spurting out of his cock everywhere.

you licked the liquid from his cock and abdomen, and started giving him a head, purposely overstimulating him as a part of the punishment.

"ah— I just came—" jungwoo protested but you were too busy to care for his pleas. he must know not to make you mad anyway.

"i don't care, woo. be a good bitch for me, and shut your nasty mouth will you?" you said in annoyance, surprising your step brother with how you addressed him informally. sassily rolling your eyes, you got back to sucking his sensitive cock.

jungwoo was certainly rolling his eyes back in overstimulation now but he can't do anything in his power, this is the first time that he had ever felt small around you, and for the second time tonight, he came, wailing like the slut he is.

you swallowed his release and instantly stood up. you took your clothing off as you manhandled jungwoo to stand up and kneel in front of you. you looked at his messy state — unruly hair, littered neck and bruised lips — and started chuckling manically, very proud of marking what's truly yours.

you sat on the bed in front of him, and sternly ordered him menacingly, "suck your favorite cock, hyungie~ c'mon be the dirty cocksucker you are,".

jungwoo was again sent shivering by your words. never in his life he was expecting to feel so small under someone's authority, but feeling so powerless, he was left with no choice but to obediently occupy his mouth with your big cock.

you felt warm saliva coating down your hard erection as jungwoo perfectly put his lips around it and bobbed his head up and down. he licked your shaft from base to the tip and played with the slit of your cock before taking it again down to the back of his neck. jungwoo then tightens his throat around your cock, causing you to send your head backwards while you release a long grunt from pleasure.

satisfied with what he was doing, jungwoo quickens his pace up around your cock and begins moaning around it. the little vibrations sent by him and his tongue swirling around your shaft have sent you flying skywards.

although being mandated under someone's authority, jungwoo really knows how to play with your cock using his mouth and tongue. he knows his way around to arouse you even more just from foreplay and oral sessions.

the amount of precum leaking from the tip of your manhood didn't go unnoticed, so jungwoo decided to incessantly suck your cock while twisting his hands around the thick shaft of your member. after a series of breathy moans filling the atmosphere of the room, you painted his mouth with your cum.

"you look so hot like this, hyung. don't be shy, swallow it~" you teased, to which he complied immediately by doing so.

"you'll only swallow my cum, you got that?" you said, lifting his chin up to look him straight in the eyes.

"y-yes. your cum and your cum only." he replied and nodded in agreement.

"good boy~ fuck i can't wait to breed your naughty hole, hyungie!" you exclaimed in excitement, looking so bright while your eyes are still filled with possessiveness and lust over your brother. you tapped your thigh eagerly as you invited jungwoo to ride you, “come here, hyung! ride your dearest step brother!”

jungwoo obediently went on your thighs and aligned your dick to his hole. he slid down your cock as he bitched out a lusty moan.

"shit, so tight!" you said, trying to adjust your throbbing cock to his figure-hugging hole. "you like this, hyung? my dick in your pussy? can that lucas stretch your cunt like this with his cock?" you added.

jungwoo groaned at your feminization, his mouth starting to open agape as he tried to reply through his breathy grunts. his eyes trying to hold the tears from falling caused by the slow and painful stretch.

"n-no, prince! only you can stretch me like this~" jungwoo grunted as he fully took your cock in him, your tip instantly hitting up his prostate. noticing his struggle, you pulled him into a kiss to distract him from the pain. you explored his mouth with your tongue as he lets himself adjust to your size.

soon enough, jungwoo made a small bounce, signalling his successful adjustment. he then began bouncing on you while moaning shamelessly.

"fuck yes— yes—! fuck my tight pussy, my prince! fuck me dumb!" he yelled on top of his lungs, "my pussy is made for you and your cock only, not lucas, not anyone— only you~" he added while drowning himself in the compelling feeling of his nerves being hit on repeatedly.

jungwoo never experienced the feeling of being this submissive over someone, but he sure as hell isn't regretting submitting to you. the experience of you degrading him endlessly, roughly manhandling him has sent his eyes rolling back. jungwoo clenched his hole while he wails in pleasure.

"ah~ you'll only tighten your cunt around me, princess, got it~" you said, continuing on feminizing your stepbrother.

he continued to fuck himself on you as you're both chasing your own highs. "i'm near~" jungwoo mewled.

"then come for me, my whore," you ordered him while you're also busy trying to get to your own climax, and on point, jungwoo released for the third time that night.

looking at his glorious state, you taunted jungwoo, "l-look at you~ already spurting for me like a fountain. you think you can handle my cock more, hyung?"

"yes, i-i c-can. just for you, pup~" jungwoo replied, to which you responded softly while running your hands through his messy hair locks, "good boy. i'm close, hyung. you ready to get filled up?"

jungwoo nodded in response. he picked up his pace, eager to get filled up already, and after a few more bounces, you greatly came inside him.

"i'm not done with you yet. be ready to be my fucktoy tonight, 'cos I'll fuck you 'til you can't walk for a month," you said as you pulled out, cum hastily running on jungwoo's thighs.

—

a few moments passed and the 2 of you have gone for a lot of rounds now. you've both gone into a lot of different positions, and right now, you are holding jungwoo on his neck while he tries to be a good pillow princess for you.

"you will only have me, and only me, hyung~ i don't care if i sound crazy, you belong to me and i belong to you~" you maniacally stated.

"so," SLAP

"don't," SLAP

"fuck," SLAP

"with," SLAP

"anyone," SLAP

"except me," SLAP

a series of rough slaps echoed throughout the bedroom as you continued to teach him a lesson, your dick bulging in his tummy each and every time you thrust into him.

jungwoo began moaning up your name incoherently as he was far too lost in his deep subspace. his words consisted of half uttered curses, trying to praise you for how good you were doing, but he's failing to do so, the feeling of his prostate getting abused from time to time being the reason why.

your step brother unconsciously came for the nth time tonight, causing you to cackle with his dumb state.

"who do you belong to, again?", you asked, poking the bulge in his stomach.

"y-YOU!" he wailed, tears streaming down his silky cheeks.

"better remember that, dear brother~" you hummed. "fuck~ you look so pretty like this, princess~ legs are spread just for me~" you continued.

"i'm gonna come~" you mewled seductively, which earned a loud response from the man under you, "y-yes, please my king! fill your hyung up!"

"yeah? you like your pussy filled with my seeds? of course you'd like that," you said, and after one last push, you came inside jungwoo again.

tired, you plop down on top of him. you tried to catch your breath and once you did, you pulled out from him without any words. you were about to walk away to go to your bedroom's bathroom when jungwoo grabbed your hands tightly, pulling you into an embrace, even though you tried to resist him, you can't do anything as you let your tears flow down due to jealousy and anger.

"sshhh, shh~ don't cry, my prince. lucas and i aren't really dating. i'm just helping him get his ex leave him alone," he tried to calm down your sobs.

"no one can satisfy me like you do, baby boy. now let's fix ourselves before mom and dad catch us, yeah?" he added.

you nodded softly as you both went your way towards your bathroom.

the night got filled with apologies and praises from both sides. promising yourselves again not to hurt each other.
