Chapter Text

Where Kim Taehyung is a sick man in his late 30s, he always had a thing for dainty pretty fragile things, 
And Koo, his babyboy was the most prettiest, daintiest small fragile thing he ever saw.

Taehyung loses his sanity when one day his wife leaves for a two weeks trip to her sister's home in Japan, leaving their teenager at home under his dad's protection.

He took his chance, and kept Koo for himself for the whole two weeks, making sure he will actually be under his protection for his entire life. 

.. 

"Daddy, s-stop" 

Koo cries confused when his dad woke him up with his big cock inside koo's soft panties, sliding it on his virgin pussy. 

"what - *hiccups* are you doing" 
Koo hiccups when Taehyung moves the small panties to a side and slide his cock between the small folds, 

Koo tries to wiggle out only to get spanked on his soft tits, which was bare, he didn't even realize it until now, his top is tucked above his plush tits, he never really wears bra at home. 

"Daddyyy- please, sorry - sorry, did Koo do something," 
Koo cries thinking maybe he did something to make daddy angry at him, that's why he's getting punished. 

"I'm sorry, - pleash, Koo won't repeat" 
Koo was so innocent, and Tae was so screwed, his baby looked so pretty under him, big teary eyes, which makes his pretty face much prettier, big soft tits with the small cute pink nipples sitting on the middle, small waist and a pretty belly button, and the perfect pinkish pussy, like he imagined. It was too small like his baby, the folds small and hooded, not letting him see what's between them, plump thighs almost squishing it between them, and white pale legs. His ass is so round, it jiggles when he walks, he turns Koo pulling down his panties all the way to look at the fat ass, fuck it, his babygirl is so pink everywhere, the asscheeks had a pink hew on them, Tae roughly spreads the asscheeks to see the small pink pucker, 

"Fuck, you are so pink everywhere" 

"Daddy- sorry, pleash Koo is sorry, daddy"
Koo cries out lying on his side, because his daddy is holding his asscheeks open and holding him down, 

Koo screams when Tae turns him over completely on his tummy and stuffs his face between the fat cheeks, licking the small hole. 

... 

"D-daddy" 
Koo pants in his fours, it been literally thirty minutes, Koo was manhandled into so many positions, for his daddy to eat his pussy and ass, and his tits. 

"nghh-dada- s'stop" 
Koo cries devastated, he really not know why his daddy is licking his private parts, he had squirted something which wasn't pee, but it definitely came out of his coochie and daddy loved it, he even praised Koo. 

"Daddy daddy, Koo gonna-Koo gonna goo-goo gonna-uh uh nwooo" 
Koo sobs arching his back squishing his Daddy's head with his plush thighs squiring again. He grabs tae's hair pulling some out making Tae groan but he kept sucking on his baby's pussy hole to drink all the juices. 

... 

Koo hiccups when his daddy take the rest of his dress off, leaving him completely naked, shivering, his whole body feels like jelly, poor baby had came twice in half an hour, stimulated so much, for the first time by his own daddy. 

"please - please no more" 
Koo covers his coochie, when Tae spreads his legs, and uses his fingers to spread the wet folds, 

"shh, shhh babygirl- let daddy take care of you" 

"Koo is sorry pleesh" 

"be good, babygirl" 
Tae warms pushing his middle finger in making Koo wriggle, holding on to Tae's veiny hand, 

"h-hurts" 

"it's nothing baby- shh, you will feel so good soon, daddy promise" 

"bad- daddy bad" 
Koo's lips wobbled saying that, when Tae forced another finger inside the mushy hole, starting to scissor him already. He wants to be inside the pretty thing already. 

Tae grabs on koo's fatass, and give it a tight spank, Koo cried in pain squeezing the two long fingers inside his coochie, 

"what do you say to daddy, babygirl?" 
Tae give another spank making Koo sniffle, tears flowing down like tap water. 

"s-sorry dada, goo sorry" 
Koo hiccups when two more spanks where given to his ass, 

"it's thank you, huh baby, repeat after daddy" 

"t-thank you daddy" 
Koo repeats quickly not wanting another spank on his sore asscheeks.

.... 

"hurts daddy" 
Koo mumbles on sitting on daddy's lap in the bath tub, his back pressed to Daddy's broad chest, daddy's fingers inside his coochie, caressing his insides, 

It been two days after his daddy started playing with him as he says, all this time his daddy had put his big pee stick inside him so many times, his coochie was so bad when daddy let him sleep after he put his milk inside him three times for the first time, there was blood and white creamy things all over his private parts and bedsheets. 

Daddy burn the sheets away, and carried Koo to his bedroom, and he stayed their for the last two days in daddy's bed, daddy gives Koo baths and feeds food, but also he puts his thing inside him every now and then making him cry all over again, 

"Daddy- mommy will - mommy will be mad at Koo" 

Koo blinks when Tae lift Koo and made him sit on his hard cock. Koo sobs getting filled to brim, it was too much, but he was getting addicted to the painful pleasurable feeling from his Daddy's big thing punishing his small coochie, 

"we won't tell mommy, right babygirl" 
Tae asks enjoying koo's tight pussy hugging his veiny cock, his boobs look like it's floating on the water, 

"look at this, how pretty you are, you got your moms boobs, but bigger" 
Tae chuckles, squeezing the soft bouncy tits, he pulls on the nipples make Koo tighten around his cock if that's possible, 

"daddy-daddy, - my binkies" 
Koo cries out thrasing on daddy's cock, making Tae almost cum. 

"stop moving around," 
Tae slaps Koo on the perky small nipple and bends him over the tub, lifting his hips up, to properly fuck him. 

Koo babbles holding the tub for his dear life, 

... 

Day - 4

"hurts, daddy pleash goo can't" 
Koo twitches on Daddy's cock, squirting again for the third time, Tae just lifts him up from his cock and throws him on the bed, he get between the shaking legs and licks all the cream his babygirl was squirting. 

Day - 5

"s-too much daddy" 
Koo hiccups when Tae bends him over the dining table and pounds into him, dinner getting cold and long forgotten. 

His big tits pressed on the table, the small nipples were red and long,  bruised after his daddy spent the whole morning sucking on them, and biting on the small buds. 

Day- 9

"nghh - uh ah" 
Koo shakes violently when Tae grabs his hips and fuck into him, he looks tired after riding Daddy for some time in reverse cowgirl position, their couch and coffee table is wet with Koo's squirt. His ass feels funny after played for so long, daddy kept licking his pucker until Koo screams and squirt from his puthy.

The movie Piranha was playing on the background. Koo cries squiring again when a naked girl practically got eaten by a small piranha, biting off her big tits. His mind cloudy with fear of something like that happening to him, it was the first time he watch something erotic and scary like that. His mommy will never let him see something like that, she always treated him as a child, not introducing to anything sexual or scarier, and now he's exposed so many new new things every day. And his mind and body kind of getting used to it. 

Day- 12

"empty- goo is empty" 
Koo hiccups totally lost when daddy kept on playing with his soft tits and ignored his throbbing coochie all day. 

His nipples got a lot plumper and his boobs are so pinkier than ever, his boobs feels heavy with the constant pleasure he's getting, and his coochie no longer hooded, it's always open like a flower, ready to take Daddy's stick anytime, his pretty hole shaped after Daddy's cock as daddy says. Always sloppy and throbbing, cockslut he calls it. 

"Dada - plis, coochie" 
Koo sucks on his lower lip and taps at his leaking hole, his boobs are so sore, and daddy kept licking and flicking, spanking and pinching, Koo can't take it anymore, his coochie is always bare, he haven't wear a panty after that day, sometimes daddy let's him wear a tee if Koo was good, otherwise he stays completely naked and now his coochie is dirtying Daddy and mommy's bed with his milk. 

"want daddy to fuck your little pink hole, baby?" 

"yeth- pretty pleashh" 
Koo cries, spreading more letting daddy see his flower in all his glory, two pink petals, open and showing the wet bruised hole, 

"hmmm!!! What about mommy, babygirl?, will you tell her about daddy fucking your little holes?" 

Koo shakes his head and grabs his Daddy's hands, 

"no no-goo promise, won't tell mommy" 

"and what happens when mommy comes back, daddy will be so sad" 

"Koo wants daddy" 
Koo sobs thinking about that, he cannot go back to how he was and he cannot stop this, he wants, he needs daddy. 

"daddy wants Koo" 
Tae hovers over the small frame and captures his baby's wobbling lips with kiss, his left hand guiding his girth inside koo's pretty flower, Koo gasp into the kiss, body is so small it thrashes everytime they connects, and Tae is mad sick to love that, he snaps his hips harder into little pussy fucking it looser, wanting to creampie the little pie. 

Koo

Chapter Text

"daddy, daddy"
Koo whispers shaking his daddy Tae in the middle of the night. His mommy sleeping next to daddy, snoring a little.

"Fuck, come here"
Tae wakes up seeing Koo in his room at 2 in the night, he drags him out and takes him to the living room pushing him on the couch.

"what?"
He whisper yells squeezing koo's plush thighs, his small gown leaving them bare,

"want - want"
Koo hiccups lifting his dress a little showing his red cunt, apparently he started masturbating a lot after his mommy came back from Japan.
Because daddy couldn't get to fuck him a lot like he did the 14 days his mommy wasn't around.
So, Koo would touch himself and tries to make the liquid come out of his coochie with his dainty fingers, but always always fails, it's not enough. And Koo haven't had an orgasm for two days now. Daddy fucked his coochie two days before while mommy was taking a beauty bath.

"fuck, what did you do baby, your pussy is so red" 
Tae touches the quivering cunt amazed, 

"touch, goo touched a lot, but-but couldn't pee milk" 

"oh, poor baby, daddy will show something for my baby" 
Tae smirks and lifts Koo from the couch taking him back to his bedroom, he opens the small locker inside his dress closet, and takes out one of his wife's prostate massagers and a set of nipple clamps. 

Koo looks confused and he let his daddy drag him again, this time to his bedroom, daddy locked the door behind them and push Koo on to the middle of the bed, flipping his dress up and lick a fat strip over the wet pussy. 

Koo moans gripping Daddy's wavy hair, arching his back when the fat tongue fill his hole so good, 

"unghh-daddy" 
Koo pants getting in his elbows to look at daddy doing wonders to his aching coochie. 

"your cock - daddy pleash - pleath" 
Koo whimpers when daddy kept sucking his puthy and ass, 

"my baby is such a dirty slut now, huh, begging for Daddy's big cock, shameless little slut" 

Koo only cries lifting his legs up, his pussy always throbs between his legs, he felt like going crazy everytime he sees daddy, but daddy wasn't touching him, he just wants daddy inside his puthy so it will stop throbing. 

"pleath" 
Koo has cute lisp all the time, which makes him more cuter, Tae curses seeing his baby so willingly presenting both his pink holes for him, so tight and so warm, so beautiful for him. 

Tae hisses pushing inside koo's warm pussy, it was so hot and Koo was already squirting for the first time, but he knows Koo will still let him fuck him numb until he creampies him, and still will let him fuck him into oblivion. 

Koo sobs in pleasure squeezing the bedsheets, his body is moving upwards with the strong ramming, tits bouncing and getting slapped, his nipples is no longer small, it's always swollen and little long, always erect inside his tops, but he doesn't care, he keeps playing with them when daddy is not avaliable. 

... 

"daddy-what is?" 
Koo trembles, cumm leaking down his pussy to his ass and daddy was showing him a purple toy, 

"this is a prostate massager," 
Tae laughs when Koo looks more confused, tilting his head, 

"this makes you feel good, baby. When daddy is not around" 
Tae smirks pushing the thing inside Koo all of a sudden turning on the vibration, Koo wails squirting right away, 

"fucking squirter" 
Tae licks his lips and gets between the quivering legs and laps the squirts, the massager was still vibrating inside his hole vigarously, making his tears flow down to his sides wetting the pillow under his head. 

"and this makes it more special" 
Tae takes the small set of nipple clamps and attach to koo's flushed long nipples, making Koo scream, 

"s-so good daddy" Koo thrashes, tossing and turning, getting into his fours, he wiggles his ass and looks at taehyung with big teary eyes, 

"fuck babygirl, you want more?" 

"goo-nghh goo miss dada in he-here" 
Koo slowly grabs his soft ass spreading it open showing his free hole, winking back at him, wet from all the squirts and Daddy's milk leaked from his coochie. 

Tae looked down to see his spent cock already twitching to get inside the small puckered hole, 

He eagerly get behind Koo and force it inside Koo making him fall forward, the clamps torturing his poor nipples, and his used pussy convulsing around the vibrator, and Daddy's big cock is drilling his tight ass rough. 

Tae left after he satisfied the needy little thing, leaving him unconscious after multiple orgasms, he made sure to dress him up and cover his small body with the thickest duvet. 

.... 

Days and weeks gone like that, daddy  Tae find time to feed his cock to his little slut, 

One morning after a few more weeks, 
Koo's mommy Miran was preparing breakfast when she heard Koo throwing up, 

She runs to her babyboy to check on him. 

"googie, what happened sweetheart, you are vomiting, shhh-don't cry," 

She comforts when koo's face turned red, eyes teary, his throat feeling funny, 

"sweetie, mommy will take you to doctor, today, okay, mommy is not going to work, you been throwing up for two days," 

Koo only cries hugging her mommy, feeling nauseous again. 

... 

"how - doctor, that's - he is only eighteen, and - and he never, I never even taught him anything, he's so pure" 

"well, Mrs. Kim don't you think, maybe his friends would have taught him or maybe he has a boyfriend, he's eighteen, you know how teenagers are now, I even took a birth for a sixteen year old last week" 

"omo, I-I can't" 
Miran cries out holding her face in her hands, 

"sorry, Mrs. Kim, let's see what we can do here, hmm, at least your boy is eighteen, he's legal, you can find his boyfriend, if they want they can keep the baby and get married" 

"stop it, he's a baby, he does not know anything, maybe he's tricked, my poor baby" 

"umm, Mrs. Kim while I was checking your son, I saw so many marks on his private and most intimate parts, I don't think it was like a one night stand, I really think you should be calm and talk to him, I am sure he has a boyfriend, who might be the one who is responsible for the pregnancy". 

Miran calms down a little and calls taehyung, 

"honey, come to home right now, Top urgent" 

She cuts the call and take a clueless Koo to their home. 

... 

"who is it, WHO IS IT" 
Miran shouts when Koo didn't answer her after asking the same question again and again. 

Koo only cried, not knowing what to say. To start with, he never really know how babies are made, but now his mommy had explained some stuff because she wanted to know if Koo really had a boyfriend or someone took advantage of his innocence. And Koo understood his daddy had not only put his stick inside him but his baby also, now he's having his Daddy's baby, his sibling, no his baby, no he doesn't know what to call it, so he cried, scared. 

"MIRAN,, what are you doing,? 
Tae came back from work as his wife asked, he opened the front door to see his wife hitting Koo, and Koo crying out saying sorrys and pleases, Tae got really angry and gets in between them, 

"Taehyung, he-he ruined our life, he is a whore, your son is pregnant, he fucking not answering me, who the fuck knocked you up, you little shit" 

She yells again trying to hit Koo again, only to be stopped by her husband. 

"what did you say, Koo is pregnant?" 
Tae asks, his face looking scarier than ever, 

"yes, he is and he is not telling me who did it?" 

Tae gulps he looks at Koo who is shivering crying his eyes out, looking so scared. Tae didn't want him to be scared, maybe he will tell the truth and that will be the end, his wife won't let him go easy, she might even kill them or just him. 

"come here, Brat, I know how to make you talk" 
Tae acted out quick and grabs Koo by his hands dragging him towards his room. 

Miran was tired, she let his husband ask Koo now, she sits on the couch mentally and physically exhausted. 

... 

Tae lock the door behind him and pick Koo up taking him to the bed, 

"shh-stop crying baby" 

"daddy-it's - it's Daddy's baby inside goo" 

"shhh, we are not telling mommy, you get it or not?"
Tae pinches koo on his thighs making him nod, tears falling down his rosy cheeks,

"now let daddy take a look, daddy is so proud of you, my baby is going be a mommy"

"a m-mommy, daddy is not mad?" 

"ofcourse not," 

"but mommy is mad at goo, she hits-hurt goo" 

"it's okay baby, it's just your mommy, she won't stay mad at you, don't worry, dada will make mommy not mad at baby, okay?" 

"okay" 
Koo's lips wobbles and tae push him down on the bed, pulling his dress up to take a look at his tummy, it was flat, but there was his baby inside, 

Koo squirms when daddy kisses his tum, he whines when daddy kept kissing his stomach, his lips leaving wet kisses until Koo is so needy, squishing his thighs together. His panties sticking to his folds where is starting to get moist. 

Taehyung notices, he kisses the wet patch and moves the panties to a side. 

"so pretty, my baby got the best pussy" 
Koo sobs at the compliment. 

He slowly opens his legs a little, allowing daddy to check out his pretty puthy.

Taehyung slip a finger in and proceed lick the wetness, he loves eating out Koo, whether his ass, pussy, mouth, his soft tits, or just his small belly button, his inner thighs or his armpits were Koo is so sensitive, 

"d-daddy, mommy-mommy is outside"

"does baby want daddy to stop?" 
Koo hiccups, saying a small no. He is so pathetic, he wants daddy all the time, even when his mommy is worried because of him and staying right outside his door, even when he understood his daddy had taken his innocence, his virginity, his mind, his body, his life everything, daddy has stolen his everything, but he can't help but keeps wanting daddy to touch him, to ruin him and make him cry, 

"that's my slut" 
Tae whispers spanking koo's booty, he turns Koo in his fours and turns him completely to another side letting him face his dress mirror, so he can see Koo crying on his cock, his tits jiggling when he fucks him silly, mouth drooling to the sheets, 

The only thing he hated while fucking Koo from behind is the fact that he can't see koo's pretty face while doing so and obviously his big tits jiggling, so like this way, he can see every details of Koo. 

Koo cries out when his daddy lift his upper body a little, so he can see himself in the mirror and push his stick all the way inside his slutty puthy. 

.. 

Miran started get worried, its been almost half an hour and her husband was still inside koo's room, and she can hear Koo crying softly, 

"honey, that's enough- maybe we should give him some time, honey come out please, I'm getting worried" 

She knocks the door and says loudly, 

After a few minutes, the door unlocked, Taehyung came out and he went to his room without telling a word to his wife. Miran takes a look at Koo, who was shaking like a leaf in the bed, small sobs leaving his mouth, she gulps thinking Tae might even hit him like she did out of anger or something, or asked him the questions again making him cry. 

She locks Koo's bedroom from outside and runs to her and tae's room to ask him. 

... 

Taehyung managed to calm Miran, he said Koo was been taken advantage by a gang of boys in another school while they had an exhibition in his school, and Koo doesn't remember any of them personally and doesn't really know who might be the father. Miran said it could be a lie and Koo might have a boyfriend for real because of what the doctor said, Tae joined her and said there might be a chance for Koo to lie to them. 

But he convinced Miran to not pry on this matter again for some time, at least until Koo feels safe enough to share it with them without being judged or questioned. For the time being, Tae planned to move to the lake house he owns in a secluded area, since Miran is working as a teacher, she couldn't move right now, 

"honey, you know I took a two weeks leave last month, now one of Teacher is resigning this week, I really can't move now" 

"I know, how about Koo and I move, I can work from home, and honey, you can come every weekends" 

Taehyung swear that was his second best plan other than pouncing on his own son, 

"but" 

"I always wanted one more child, we will take care of him or her as our own and that way Koo wouldn't have to ruin his future, also if we move, there is no one there anywhere close, and no one should have to know about this, later after the birth, we can say it's ours, we had a surrogate or something,"

That's a brilliant plan Kim Taehyung, he thought to himself. 

"that's okay, but honey Koo is pregnant, he needs me, he is small" 

"you know when you got pregnant with Koo, who took care of you, hon?" 

"you, thank you honey, then let's do that I guess" 

"yes, don't worry about anything, I will take good care of Koo" 

Tae hugs Miran, his smirk growing big, finally he can have Koo to himself forever..
