(Warning: taehyung is underage in some 18+ scene)
Jeon Jungkook was 20 years old when he was married to Kim Taehyung who was 12 at that time. The marriage was for protection of taehyung who had some bad luck looming over his head only marrying him to a virgo beauty born in middle night in starting of month September could have saved him from dying at early age.
Taehyung being the only son Of kim couple who weren't able to conceive another, was the reason those poor couple searched village after village for the person who matches the discription given by the priest who had read taehyung's fate after the boy had turn ten for whole two years after that taehyung stayed ill no amount of medicine and herbs were able to cure him and than they finally found the cure in Jeon Jungkook a beauty born in middle night starting of September.
Jungkook's parents were poor with many children so few money thrown by Kim's had them willingly marry their son to a small boy. Jungkook didn't denied either if marrying him can save some one life than he was ready to do anything he too believed in God and fates very much maybe it could be the reason why he's born in first place to save taehyung from this misery.
Jungkook and taehyung marries soon and to everyone shock taehyung's illness really starts to fade, the boy starts to get better within days under jungkook's and his parent's doting and then finally one day turning 13 taehyung becomes a health young teenage with no more illness and nightmares. The small boy likes his wife very much who saved him that he follows jungkook around like a puppy, making his wife laugh with his cute antics is his favourite thing to do.
"Tae baby drink your milk first than wifey will play with you" jungkook coos softly to his young husband ruffling taehyung's fluffy hairs who's currently sitting on a dining table a glass of milk given to him by his wife. Taehyung chugs down the glass quickly making his mother and grandmother smile happily at Jungkook who's able to make taehyung do everything with his soft voice and promises of playing with the younger.
They both plays to their heart content playing mostly hide and seek for some reason taehyung likes searching for his wife and seeing the expression on Jungkook's face when taehyung grabs him tightly after finding and squeezes his small waist in happiness. Jungkook then leaves taehyung to complete his school homework while he help mrs. Kim in kitchen both cooking dinner for the family.
Later at night both taekook gets ready for bed, taehyung waiting patiently for cuddles while jungkook does his skin care routine. Jungkook wears a long nighty with spaghetti strips soft and comfortable on his skin also for some other reason. "Hurry up! Koo i have to get up early tomorrow for math test!!" Taehyung whines, the young boy is only in underwear as he doesn't like wearing clothes to sleep they itches his skin at night he had told that to jungkook from the very starting.
"Coming baby just a minute" jungkook replies softly braiding his long hairs so they doesn't tangles at night. He then locks the room door turning off the light on his way. Jungkook gets inside the duvet giggling when taehyung attacks him hugging him tightly. Taehyung sighs pressing his face in jungkook's chest feeling the squishy meat there he nuzzles a little whining when the silk nighty doesn't slips away. Jungkook understanding his motive slides the spaghetti strip from his shoulder pulling it down so one of his tit frees from the nighty.
Taehyung quickly attaches his mouth on the perky nipple draping his limbs over jungkook as he suckles like a baby, quickly sleeping as soon as the naked meaty tit squeezes against his face. Taehyung used to sleep while sucking his thumb so to stop that habit grandmother kim told jungkook to swipe the thumb with his breast so her grandson changes this weird habit of sucking thumb and jungkook being the polite son in law does what grandmother commands it's been two months that taehyung sleeps while suckling Jungkook like a newborn baby.
