#kinktoberbts_d5: butt plug/dildo

this has probably been done a million times but ot6 training koo’s holes :D

cw // free use, dildo gags, humiliation, piss, sounding, inspection

baby being sooo tight and so bad at taking cock everywhere :(((( comes back home after a hookup upset at having to top again bc his hole is so small and giving the worst blowjob ever bc he kept gagging :( he’s not used to being bad at /anything/ so ofc hyungs offer to help !!!

sj starts him off on a tiny little plug for his ass, the stretch so unsatisfying and barely there…

until hyung tells him he has to keep it in all day

everyone gets to enjoy the sight of his little chubbed up cock forming the cutest bulge in his sweats all day,

the tiny plug being jostled at every little movement

after a few days, sj works a bigger plug into him, and then bigger still, sometimes making kookie wear them overnight. he always gets so worked up, can’t settle down and sleep until sj wrings a few orgasms out of his

over-sensitive cock

eventually koo is ready to take any of their cocks, even sj’s massive girth, at any time. hyungs only have to pull the plug from his clenching greedy hole, shush his whining at being empty and sheathe themselves in him in one long thrust

of course the plug gets pushed right back in when they’re done using him, with the added bonus of keeping the hot cum inside <33

jm’s the one to find dildo gags to start training his throat. koo looks so /cute/ walking around all drool-wet and messy, having given up trying to wipe it off his face after the first hour

jm can’t help but pull him into his lap and kiss him silly, pecking and licking at his

lips where they stretch around the gag, working his tongue into the gap between the dildo and the inside of his cheek

loves taking the gags out almost as much as he loves putting them in: likes to watch jk’s teary eyes and the way long thick strings of drool connect jk’s wet

mouth to the dildo, likes pulling it back until the strings almost break, before bringing it to wipe on jk’s face

talks about how little boys needs to clean their own messes, as he makes sure to wipe off every bit of drool on the dildo over his entire face

tete lovessss being a little menace and making jk’s life difficult when he has his gag on. sometimes he’ll tie jk’s hands behind his back, so jk has to come and ask him if he needs anything, all muffled whines and teary eyes behind the gag.

tae always spends a good few minutes cooing at him and "trying" unsuccessfully to decode what he’s saying

“silly baby try and speak up” “hyung can’t understand u bunny, say that again”

jk’s dick twitches so cutely at the humiliation of it all

tae also loves helping him pee! just something about the vulnerability of koo having to come and ask, the humiliation of him having to squeeze his legs together and mime being desperate when tae pretends he can’t understand what he needs

tae will escort jk to the bathroom with a hand on the small of his back and then stand behind him and hold his dick as jk squeezes his eyes shut, cooing about how hard he is and suggesting that maybe he needs to cum first

gets one hand to press and rotate the plug in his ass

while the other strokes his cock until he’s cumming into the toilet bowl, quickly followed by a hot stream of piss

tete squeezes and releases his dick to play with his stream, stopping and starting until koo is whining

throughout it all, his humiliating commentary doesn’t stop once:

“oh sweetheart u were so desperate hm, why didn’t you go sooner?”

“doesn’t that feel so much better little love? let’s get u all cleaned up now, messy boy”

yg introduces them to sounding, arguing that if they’re stretching all his holes they can’t forget his pisshole!! there were tears the first few times, but now koo LOVES it too. will sometimes go to yg, shy little toes curled inwards, and tell him his pee hole feels empty :(

sometimes yg sits him in his lap, arms wrapped around his waist, one hand holding his dick up while the other works a thick rod carefully into jk’s tightest hole

other times, he’ll coax jk to hover over him, will hold the sounding rod close to his cock, and talk jk through

fucking himself on the rod, little aborted thrusts to start off with until he gets too lost in the pleasure to be cautious

yg hopes he’ll be able to get a finger in soon 😌🙏

namseok def like to think of themselves as overseeing the whole process, making sure jk is making the right “progress”

a blushing koo has to come to them at the end of every day and hold his ass cheeks open so nj can pull the plug out half-way, push it back in, repeat the motion

a few times until koo is panting and drooling and nj is satisfied koo is taking the plug well

hs is mirroring nj's actions on jk's other end, tutting every time baby gags. hhhh just poor koo bent over like a slut and trapped between their rough ministrations and dirty words,

nj working a hand between his thighs to grope his cock at the same time as hs pinches his hard nipples, so it’s no wonder kookoo moans so lewdly that the others come and watch, showering him in condescending praises as he spills all over the floor

anyway koo forgets all about his initial plan of getting better at sex things to impress his hookups, and ot7 live happily ever after <333

maybe hyungs teach him rimming next 😳

🦇🦇🦇

I wrote most of this on my phone with the brightness turned all the way down during a really boring lecture 😭 I hope u guys enjoyyyy <33
