Work Text:
JungKook was a teenager, 19 year old, he had lots of interest in gaining muscle, not that he wasn’t already all buff, he was too huge, he didn’t look like a 19 year old.
He had a pretty little brother, Jimin, he was 6 year old, ever since JungKook saw Jimin naked, he just couldn’t wait to fuck the baby pussy, JungKook find out about it when Jimin was 2 years old
It was the weekend and their parents left for a trip, leaving Jungkook to babysit Jimin.
JungKook woke up and went to the living, he saw Jimin, pretty little boy was watching cartoons.
JungKook went to the room attached to the living, it was the gym, JungKook was wearing short, he took his shirt off, there was a huge mirror in the gym.
[This is not an edit, JungKook himself posted this photo of him in gym]
JungKook always checked his toned body, chest, abs, and flex to see the bicep bulge, his daily routine was to workout, sometimes Jimin would come to play with his hyung as well.
JungKook was already having a boner, he began with the treadmill, after 15 minutes he was done with it, he sat on the floor, breathing heavily, he saw Jimin approaching him with his little baby feet.
Jimin was a 6 year old but his height was so small, closer to a 4 year old, JungKook was fascinated as he look at Jimin making the small steps towards him.
Jimin came in with a little shy smile, “Hyu- Hyung- why are you naked?” Jungkook sign and chuckled a little, “I’m not naked mimi, I’m just not wearing the shirt”
Jimin smiles shyly moving around and coming closer to hyung, Jungkook sat on his knees when Jimin came closer, even then Jimin was smaller.
Jimin hugged his hyung and Jungkook hugs back, the tiny hands of Jimin on JungKook’s insanely broad back was making him go insane, Jimin said, “Hyungie, I want to play too”
Jungkook looks at his adorable brother, he gave up, he had the idea in mind, he said, “Okay Jimin, let’s play gym”
Jimin knew what his hyung meant, JungKook held Jimin, one hand on his thigh and the other on Jimin’s upper belly, held him harshly as he stood up quietly and moved Jimin up and down, used Jimin like a dumbbell, an object to use for weight lifting.
Jimin always had the lust in his eyes for his big brother, his brother was so big and caring, he carries Jimin around as if he weighs nothing, just like a feather, hyung is so strong
JungKook kept moving Jimin up and down, now with more speed, using the boy to weight lift, even though it was so easy to lift Jimin’s little body up and move around.
He then sat on the mat, Jimin asked with a pout, “Hyung, why you always work out? you’re so strong” to which in response, JungKook rub his manly hands all over Jimin soft cute face, he answered, “Mimi, it’s because hyung wants to be all strong, so he can protect you from bad guys”
Jimin was so touched after hearing that, JungKook loves him so much, his hyung’s gonna protect him, he was feeling at ease.
JungKook then got into a pushups position, He gestured Jimin to do what he always do, sitting on JungKook’s broad wide back while he does the push up, Jimin lays on his back and Jungkook feels his soft body, touching Jungkook’s raw rough back.
Jimin slides under his hyung sneakily, while Jungkook doing the push-ups, JungKook saw Jimin looking so innocent with doe eyes under him, whenever Jungkook went down in push-ups his dick was poking in between Jimin’s thighs.
JungKook hissed at the sensation, “Mimi, you like it when hyung plays with you?” While continuously doing the push-up now in a fast pace.
Jimin said, “Yes hyung, mimi wants to play more”
JungKook dick was so hard right now, he was doing the pushups as if he’s thrusting, cock poking through the shorts, the tip was almost out of the shorts from the bottom opening of the shorts.
Jimin made a cute face and gave a peck to Jungkook nose, making Jungkook go crazy on the pushups, Jimin then held the JungKook’s chain, which was touching his face everytime Jungkook came down during the pushup, started playing with it, cute pout on his face, while JungKook kept doing the pushups in a fast pace, looking at Jimin with dark eyes.
When Jungkook was close, he stood up and went straight to his room, without saying anything to Jimin, curious little boy went to his hyung room and stood by the door, peaking as he saw Jungkook putting his shorts down and his hyung’s pipe like thing was out.
Jimin eyes wide opened, it was so big, JungKook started giving himself a fast handjob, it was doing something to Jimin, he was feeling hot in his little flower, Jimin was clenching his legs and felt the urge to touch his flower part.
Jimin didn’t knew what was happening, JungKook had a container besides him, he gave few more strokes before he came, thick load of cum, he did a quick action of putting the container in front of his tip, with groans he came in the container, half of the glass like cup container was filled with while liquid.
JungKook came a lot, he then looked over and stared darkly at Jimin, he knew all this time that Jimin was watching him, Jimin felt his soul leaving his body.
The dark gaze of his hyung, Jimin quickly rushed back to his room.
It was the lunch time, they both ate and after that, JungKook gave Jimin the smoothie, Jimin looks at his hyung, JungKook said, “Drink it baby, today we will play gym a lot”
Jimin drank it, it was white and very salty, Jimin drank it all innocently, he was struggling to swallow it all down, it was very thick and sticky, JungKook just smirked, he made Jimin eat all his cum.
It was the night and Jungkook was feeling his dick getting hard again, he grunt and called Jimin, baby was just wearing a long hoodie, JungKook made Jimin sit on his lap.
JungKook whispered in Jimin’s ear in a low tone, “Mimi, let’s play more gym, you just have to be an obedient gym toy for your hyung”
Jimin nodded and said, “Yay, let’s play hyung, mimi is so excited” JungKook quickly undressed Jimin and as per his guess, Jimin wasn’t wearing anything underneath it.
He looked at the hairless beautiful pussy hole, JungKook said, “Baby, hyung’s gonna play gym with you differently”
Jimin nodded, “Okay hyung” while Jungkook started rubbing his fingers all over Jimin’s pussy hole.
JungKook pushed one finger in, making Jimin squeal, JungKook held Jimin down, he said, “Baby, be quiet or hyung will never play with you”
Jimin said with a pout, “Mimi is feeling weird hyung- flower is all hot” JungKook didn’t respond and just looked with stern grin, he spread Jimin legs more roughly and kept thrusting his finger, he pushed in another finger.
When Jimin was about to come, JungKook suddenly stopped, he purposefully did that, he likes to be mean to his little brother, this was a whole new experience for Jimin, he felt so close to his hyung right now, he felt like he was gonna pee.
JungKook then pulled out his 9 inches cock out of his shorts, looked over at Jimin, the boy face was getting all red from shyness, he said, “Hyung, why are you showing me your pipe thing, mommy said it’s not a good thing”
JungKook spread his legs more on the bed, making Jimin legs spread more, as he’s sitting on him, JungKook answered, “Aww mimi, mommy was wrong, all brothers play this gym game together”
Jimin was lost in thoughts and pouting in such a cute way with doe eyes, innocently looking at his big hyung, he said, “Oh really, so now it’s time for your pipe to work out?”
JungKook dick twitched at the innocence and words, he said, “Yes mimi, hyung’s long pipe wants to work out, it needs you, so hyung can get more stronger for you”
Jimin eyes lit up, he’s gonna help hyung get more strong, this is the best thing, he said, “Mimi is all shy, hehe hyung, let’s play gym” he said while feeling Jungkook’s biceps, having his tiny hands all over Jungkook’s chest.
JungKook held tiny hands in his rough tattooed hands and put it on his grithy cock, he was so hard, considering he came so hard in the morning, Jimin cuteness never fails to make him rock hard, he wants to bury his dick right in small pussy of the boy.
Jimin was enjoying moving the pipe up and down, using his both hands, with full force, yet he wasn’t able to hold it fully, JungKook dick was bouncing now, which made Jimin look at it with excitement, he said, “Hyung, look it’s moving by itself”
JungKook stopped Jimin hands, moved him closer to him, slapped the wet pussy of Jimin with his rock hard cock,
JungKook said, “Mimi, you’re a good brother right? Hyung will put the pipe in you now, be quiet like a good toy for hyung’s workout, understood?”
Jimin nods cutely, JungKook pushed his dick inside, the tip went in, it was so tight, Jimin was all okay now, until JungKook’s next move.
He pushed in 4 inches of his dick in one go, Jimin felt his flower stretching by the thick pipe, he said, “Hyung, this workout hurts mimi, let’s not do it”
JungKook coos at the boy and with a grin, he held him in a harsh grip, spanked his cute little butt so hard and said, “Ahh mimi, you want hyung to protect you from the bad guys right?”
While pushing in more of his dick, 6 inches was in, Jimin squeals at the assault being done to him, he manages to babble the answer, “Yes, i want hyung to protect me”
To which in response, JungKook did a sudden thrust in, he said, “Aww then you must help hyung with this workout, now be a quiet little toy or else, hyung will get mad”
He started thrusting, making Jimin tremble his legs and starts to protest to move away from the big pipe thing, which is destroying his little flower,
JungKook got so mad at this, there’s no one in the house, he can do anything to Jimin and it’s time he tells the little boy his place, he’s just a toy for Jungkook.
He pulled out from Jimin pussy and looked at the boy with dark eyes, he grabbed Jimin’s small butt so harsly with his strong hands, groped it making sure to leave bruises, printing his hands over the surface of his ass.
Jimin looks up with a pleading look, to which in response Jungkook grip got more harsh, literally pinching the boy’s plump ass with his strong hands.
Jimin was a cry mess now, JungKook dick was touching his own toned abs, it was twitching seeing the little boy struggling because of the insane abuse.
After 5 minutes of silent treatment, making Jimin cute butt all red, leaving his hand mark on it, he’s now JungKook’s, he was sure that those bruises will stay there for at least a month.
JungKook suddenly left the grip and looked at the shaking boy, looking so tiny in front of his huge figure
He then said, “Mimi, hyung’s so mad right now, i told you to act like a gym toy, why can’t you. Don’t you want hyung to get more stronger?”
Jimin with hiccups tries to speak, he said, “Hy- hyung is hurting mimi” to which in response, JungKook grabbed the already bruised ass of Jimin, this time not that harsh.
He was shocked and thought that Jungkook will again do the same thing, he was already in pain because of the harsh grip, so in a hurry he said, “Hyung, okay i will be a quiet toy, please use me for the workout, mimi is ready”
JungKook smirked, the way he tamed the little boy into being an obedient little fuck toy for him, oh it dick was so hard right now, he wasn’t going to go slow this time on that baby pussy.
He said, “Aww mimi, you’re such a good little brother, now I don’t want to hear any words from you, let hyung pipe do the workout”
He pushed in his dick again, 6 inches in one go, he wasn’t going to stop there, Jimin had his cute hand over his mouth, so he doesn’t let voice out.
JungKook said, “Aww, my baby brother is so cute, more inches is coming for you, hang in there”
Saying this, he stood up, held Jimin in his arm, pushed his entire cock inside the tight cute pussy of Jimin, his long veiny dick buried inside the most beautiful little pussy, it was making him go insane, the belly bulge his dick was creating was so huge, looked like little mimi got pregnant.
Jimin was so lost at this point, he didn’t knew what was happening with him, he tried his best to stay quiet and act like a toy for Jungkook to workout.
While JungKook started thrusting in a animalistic pace, he waited for this moment for 4 whole years, he is finally taking the virginity of his little brother, raping the shit out of little mimi.
Jimin tries to have his hand wrap around Jungkook broad back and shoulder but wasn’t able to, he was so tiny in front of him.
JungKook fucked into Jimin while standing, pushing and reaching new spots, he felt Jimin getting close, this time, he started to thrust in fast, he wants to see how a 6 year old would come on his cock.
With few more thrusts, Jimin was about to come, he screamed, “AAAAAA HYUNG STOP, MIMI IS GONNA PEE”
JungKook kept thrusting, Jimin was again protesting, this time, JungKook held him tight and fucked into the hole as if it’s a flashlight, Jimin came, it wasn’t a lot, which was expected from a 6 year old.
But it was enough to wet JungKook’s cock, he reached a new high and started going in deep, he can feel Jimin’s uterus, oh he’s gonna fill the boy up, he has no plan to come outside of that beautiful hole.
JungKook with sudden harsh thrusts said, “Mimi, workout is about to end soon, you want hyung to cream inside you right?”
Jimin with a childish mind said, “Hyung, it hurts, will it make- will it make- mimi strong?”
JungKook felt his dick twitching inside Jimin’s pussy, he answered, “Oh yes baby, hyung’s cream will make you strong”
JungKook knew he was gonna get a lot more rough so this time, he put one hand over Jimin mouth, closed his cute plump lips, while he make him lay on the bed, he became so wild and started thrusting again.
The new position made his dick poke the uterus of the little boy, he’s afraid he might break it, he was so close, the feeling of having the tightest baby pussy around his dick, using his own little brother as a fuck toy.
He looked at the boy with stern dark eyes while he thrusted, chasing his orgasm, Jimin was a crying screaming mess, but no one can hear it, little mimi is getting raped so hard by JungKook and the naive boy thinks it’s a workout for his hyung.
JungKook groans and said , “Yes, mimi, such a good boy, stay like that”
With some more powerful thrusts, he finally came inside Jimin, filling the boy’s uterus, he emptied himself and laid on the bed with his dick still buried inside the boy, he pulled the sheet over them,
Jimin after coming back to his senses asked, “Hyung, workout is done?”
JungKook answered, “Yes baby, you made hyung release his stress and I’m a lot more stronger now, all thanks to you mimi”
Jimin blushed at that, his hyung is being so sweet, but Jimin still remembers how rough hyung got with him just some minutes ago, he asked while still laying on Jungkook hard chest and abs, “So hyung, when will you pull it out? Your cute gym toy is tired”
JungKook had a sick plan, his dick was still hard, he didn’t wanted to pull out of that pussy, he wants to use Jimin to cockworm him.
JungKook said, “Aww, Mimi must be tired, Hyung will pull out soon, he just want to stay close to you, you can sleep on top of me”
It took a while for Jimin but after sometime, he felt his legs getting numb, he knew he can’t fight his hyung, so he took it and slept while JungKook’s 9 inches cock was buried inside him.
JungKook knew they would have another session in the morning, he slept as well.
