Work Text:
taehyung was only 16 when he met his mother’s new boyfriend—jeon jihyong and his son, jeon jungkook.
jihyong is very kind to him and to his mother. so he doesn’t mind if one day, his mother will end up marrying the man.
taehyung’s only dilemma is his soon-to-be step-brother. jungkook is three years older than taehyung. he’s not rude or anything, but he’s distant. and he seems scary sometimes because of his dark aura. always wearing dark clothes and he has a lot of piercings. as time goes by, taehyung notices the tattoos slowly covering his whole arm like a sleeve.
he would like to get to know the older, but the thing is jungkook doesn’t visit them all the time like his father. he doesn’t join their little trips and dinners. it’s like he doesn’t want to get to know taehyung and his mother.
but things changed when his mother and jihyong finally got married. when taehyung and his mother moved in with the jeons. when taehyung’s finally 18 and jungkook is 21.
“your room is here, taehyung-ah.” jihyong smiles at him before opening the door of his new room.
taehyung’s big round eyes wander around the room in awe. it’s so big and beautiful! it has pastel purple walls and a queen sized bed. there’s also a lot of beautiful decorations such as the big teddy bear lying on the bed. it’s so cute!
the 18-year-old knows that the jeons are rich, but he didn’t expect them to spend much for taehyung.
“thank you so much, uncle jihyong .” taehyung said, bowing a little to show respect and gratitude to his mother’s new husband.
“don’t thank me, son.” jihyong chuckles. “it’s all jungkook’s idea—oh, by the way,” then jihyong pointed at the door across from taehyung’s room. “that’s jungkook’s room so if you need anything, you can just knock on his door. i’m sure he won’t mind.”
taehyung nodded his head. though, he’s pretty sure he won’t ever knock on jungkook’s door in fear of being rejected. he doesn’t know if he can take it if jungkook got mad at him and humiliate him for disturbing the older.
taehyung spent his first day at the jeons’ house filling up his new room with his things. his art materials, his books, old photographs of him with family and friends. he doesn’t have much clothes but he was so surprised when he saw the closet filled with brand new, luxurious clothes.
“mom, what is this?” he asked, eyes wide staring at the huge closet.
his mother smiled, squeezing his shoulders. “they are yours, sweetie.”
“w-what? did you and uncle jihyong bought these clothes for me?”
“i don’t think jihyong knows how to shop for kids your age and i was surprised to see this too. i’m pretty sure it was jungkook’s idea.”
jungkook. so he didn’t just prepared the new bed room for taehyung, he bought clothes for him too.
“oh, by the way, tae. i just wanna remind you that jihyong and i will be leaving tonight for our honeymoon~” his mother giggled.
taehyung winces, “right.”
he almost forgot about that. the wedding was yesterday and jihyong and his mother didn’t left right away for honeymoon since they have to settle in the jeons’—their new house first.
they planned to travel around Europe and it’ll take them a month before they come home. it’s too long for taehyung but he doesn’t want to complain about it. he wants to give his mother and jihyong some time alone because they deserved it.
however, he’s going to be left alone with his older step-brother who doesn’t even talk to him. it’s going to be so awkward, taehyung thinks.
“taehyungie loves pastas, especially mac and cheese. i hope you’ll love it too, jungkook.” his
mother said while preparing the table for dinner.
taehyung pursed his lips, looking down at his empty plate. he can feel the presence of the older who’s currently sitting in front of him. when taehyung steal a glance, he saw that jungkook’s wearing a white shirt with a chain necklace. he can perfectly see his tattoo sleeve even from his peripheral vision.
he looks cool, taehyung thinks. some boys from his high school are lanky and acts cool but the truth is, they’re all lame.
jungkook, though, looks big and muscular. he looks like he go to the gym. well, maybe it’s normal for college boys. since they’re all mature and old.
taehyung was too caught up in his thoughts that he didn’t notice the hooded eyes staring at him.
it was 9 P.M when jihyong and his mother has to leave for their flight.
“jungkook, you’re in charge so be responsible. especially now that taehyung’s here. if something happened to him, it’s your fault.” jihyong told his son, strictly.
“jihyong-ah, they’ll be fine!” taehyung’s mother chuckles. “i’m sure jungkook will take care of our taehyungie. and my baby is not irresponsible. he’s old enough to take care of himself, too.”
“you’re saying that but you still call me your baby,” taehyung smiles faintly.
“because you are my one and only baby!” his mother said before kissing both of his cheeks. “take care, you two. don’t be rebellious and i hope you’ll get along well!”
“we’ll be fine,” jungkook said. “have a safe trip.”
“enjoy, mommy! uncle jihyong!” taehyung waved good bye with a big smile on his face.
like what taehyung expected, it was awkward. for the first three days, they don’t talk. jungkook will cook for them and they’ll eat breakfast, lunch, and dinner together. but that’s all.
taehyung’s summer break is finally over and he’s back at school. he’s in his last year of high school and he couldn’t wait to graduate.
jungkook will drop him off at school, then pick him up when his classes are done. good thing that their schedule matches.
after a few days, the two finally started talking. simple things like what taehyung wants for dinner or if jungkook wants to watch an animated movie with taehyung. it’s random, like their conversation during car rides.
taehyung found out that jungkook has his own apartment but chose to live with his dad. the apartment is gifted by his grandparents, and sometimes he stays there.
the younger couldn’t help but think that if he’s not in the jeons’ house, maybe jungkook is staying at his own place right now. instead, he’s babysitting an 18-year-old high school student.
“taehyung-ah,” jungkook’s low voice snapped the younger out of his thoughts.
taehyung looked at jungkook with big round eyes, “huh?”
“i asked if you want pizza for dinner since i’m lazy to cook,” the older chuckles at taehyung’s cute lost face.
“it’s fine, hyung.” taehyung smiles.
taehyung thinks they’re slowly becoming friends since jungkook told him to drop formalities.
the younger likes to think that he can be close to jungkook like a real brother.
oh, how wrong he was.
after two weeks of living together, they became more comfortable with each other. taehyung can now freely move around and joke around with the older. some mornings, he’ll go to the older’s room and wake him up so he can make breakfast for the both of them. sometimes, jungkook will drag him to the bed so he can cuddle with the younger. and taehyung will end up giggling because he’s very ticklish and simple touch can tickle him.
so many things changed between the two. but taehyung didn’t notice the dark stares of the older whenever taehyung’s walking around with oversized shirts and boxer shorts. or jungkook’s simple touches on the younger’s thighs during car rides, or his arms around taehyung’s waist.
taehyung didn’t mind all those things, thinking that jungkook’s just affectionate.
until one evening while watching a new animated movie as the two cuddles on the couch, taehyung notices that jungkook was extra touchy. he’ll gently caress taehyung’s back as he nuzzles the younger’s hair.
taehyung enjoys the doting, though. he’s very affectionate too and touchy with his friends. his best friend, jimin once said that it’s his love language.
“h-hyung...” taehyung whimpers when he felt the older’s large warm hand slipped inside his shirt.
their position is already questionable if you’re going to ask a different person, but for taehyung, it’s normal since this is not the first time they cuddled like this.
jungkook lying on his back with the younger on top of him. taehyung snuggled more into the older’s broad chest, hiding his flustered face.
“hmm? what do you want, baby?” jungkook asked in a low voice with a faint smirk, knowing that the younger is affected by his touch.
taehyung shook his head in response, biting his lower lip to hide his pathetic sounds.
the older’s hands suddenly went down to taehyung’s round plump ass. jungkook wonder if they’ll jiggle if they got spanked.
but he thinks it’s too early for that. he doesn’t want to surprise the younger so instead, jungkook squeezed both cheeks with his large hands, making the younger gasp in surprise.
“hyung! w-what are you doing?” taehyung stutters, surprised and confused by the older’s actions. they’re not supposed to do this, right? they’re brothers now!
“don’t you play with hyung, baby?” jungkook whispers to the younger’s ear.
taehyung can feel the hair at the back of his neck rise. the older’s hot breath against his skin is tickling, making the younger blush even more.
“isn’t this... w-wrong? i don’t— i don’t wanna get into trouble, hyungie.” taehyung whimpers.
“sshh,” jungkook caressed his unclothed hip, “we won’t get into trouble if you won’t tell anybody.”
that’s how taehyung ended up getting his pussy fingered while lying on top of the older. he touched himself before out of curiosity but he have never had someone touching him like this.
it feels so good. jungkook’s fingers are thick and long and taehyung can feel them so deep inside his pussy. while jungkook’s other hand is fondling with his ass cheek, squeezing and giving it light spanks, making the younger jolt and whimper like a kitten.
jungkook changed the angle of his fingers and when the younger let out a squeak, jolting in surprise, jungkook smirked, knowing he found the younger’s sweet spot.
“h-hyungie... feels weird—‘s weird...” taehyung mumbled, weakly.
jungkook looks down at taehyung who’s lying on top of him and he saw the younger’s drool is already on his shirt but jungkook doesn’t mind. not when taehyung looks wrecked just by getting fingered.
“feels good, hmm?”
“y-yeah but—Ah!” taehyung shut his eyes, lips apart as he moans while jungkook started to fasten his pace, dragging his fingers in and our of taehyung’s cunt, making sure to abuse the younger’s sweet spot.
“hyunggg... nghh..” the younger sobbed, “i’m gonna come... g-gonna come.”
suddenly, jungkook switched their places. with taehyung lying on his back and jungkook in between the younger’s thighs.
“fuck, tae, you’re so wet.” jungkook stared down at taehyung’s soaked white panties. he can clearly see the pretty pinkness of taehyung’s pussy.
the older didn’t waste any time, he quickly removed the younger’s panties. his finger trailing between the folds, making the younger squirm and whine.
“let me play with your pretty pussy first, tae. then hyung will make you come, okay?” jungkook looked up at taehyung with hooded eyes, a mischievous smirk on his face.
“mmhm,” taehyung nodded. “o-okay, hyungie...”
“you’re so fucking good for hyung, baby.” jungkook smiled softly before sucking on the inside of taehyung’s thighs, leaving marks.
jungkook parted the pussy lips using his fingers to see the cute nub hiding behind the folds. he gave it a quick lick, then licking a stripe from taehyung’s hole to his sensitive nub.
“hngg! hyu-hyung!” the younger sobbed in sensitivity. “p-please...”
jungkook didn’t listen to the younger, instead he focused on playing with the pretty cunt in front of him. giving it a teasing licks before lapping on it like a starved man. it’s glistening with slick and jungkook’s spit. it tastes so sweet.
“fuck, you taste so good, baby.” jungkook suddenly sit on his knees, unbuckling his belt to free his hard length.
“hyung...? i’ve never—“ taehyung looks away, blushing furiously.
jungkook stopped his movements. of fucking course, taehyung’s a virgin. he’s only 18. fuck. the realization makes jungkook shake in arousal and hunger.
he’s going to make the younger his. after this, no one will ever touch taehyung except him.
“don’t worry, baby.” jungkook leaned down to give the younger a kiss on the forehead, “i’ll be gentle, okay? hyung will take care of you.”
taehyung looks at the older with a glossy eyes, pouting. “kiss?”
jungkook chuckles before giving the younger a kiss. they made out quickly. it was messy and wet, but they loved it.
the older went back sitting on his knees after. he parted the younger’s leg, stroking his hard length as he looks down at taehyung’s glistening cunt.
“hyung... i’m scared...” taehyung whimpers pitifully.
“ssh, baby, it’s okay. hyung will make you feel so good.”
and that’s exactly what jungkook did. he fucked the younger relentlessly, fucked him dumb until taehyung couldn’t speak properly anymore. just letting out soft cries and moans. cute noises that jungkook adores so much.
“hyung—nghh!” taehyung arches his back when jungkook found his sweet spot again. “ah! ah!”
“feels good, baby?” jungkook grunted, ramming inside the younger.
“g-goo—“
the older chuckles, seeing how taehyung can’t even complete his words anymore. his eyes hazy and teary, cheeks so red like a rose, and lips swollen from jungkook’s rough kisses. his neck down to his collar and chest—they’re all covered with jungkook’s marks.
“gonna c-come... hyung!”
“yeah?” jungkook fasted his pace, “come for me, baby. come for hyung.”
taehyung let out a squeal when he finally came. but it’s not enough for the older. jungkook spanked the younger’s pretty cunt until his squirting and screaming from overstimulation.
“g-gukkie! stop! hyung!” taehyung sobbed, trying to push jungkook away but useless.
jungkook laughs, finding the younger cute, before leaning down to crashed his lips against taehyung’s lips. then he started fucking him again relentlessly to chase his own orgasm, shutting up the younger with his kisses, swallowing his moans and whines.
when jungkook came, he thrusted so deep inside the younger that taehyung can feel jungkook’s come so deep in him.
“fuck,” jungkook growled, nuzzling the younger’s neck.
“hyung... i feel s-sticky.” he heard taehyung said in a small voice.
jungkook smiled tiredly before removing himself from the younger. he looked down at taehyung’s pussy before parting the folds to see his come oozing out of the younger’s hole.
the older wants to take him again, fuck him again, but it seems like taehyung’s too tired to even move. the younger needs to rest.
he stood up before carrying the younger in his arms. he went straight to his bed room to clean up taehyung.
it wasn’t the last time it happened. it happened again and again. every night, even at the morning before they go to school. sometimes, right after jungkook picks the younger up from school—inside jungkook’s mercedes benz.
if you’re going to say that jungkook is a sex addict, he might believe it. but only to taehyung.
he doesn’t care if it’s wrong. he doesn’t care if they’re supposed to be brothers. they’re not blood related or anything so he doesn’t care.
he also make sure that taehyung enjoys what they’re doing. he knows that taehyung does because there are times when the younger was the one who initiates. when jungkook’s cooking for breakfast, taehyung will come to the older and tease him. they’ll end up fucking on the countertop.
nothing changed. even when taehyung’s mother and jihyong came home. both surprised to see the change in taehyung and jungkook’s relationship.
they didn’t know that every night, jungkook will sneak in taehyung’s room. the older will make taehyung bite on his pajama shirt so he won’t be so loud while the older’s pounding inside taehyung’s cunt.
