Work Text:
Koo grumbles in his sleep, the sleeping pill showing it’s magic. Namjoon smirks as he gets to work slowly and teasingly pulls down his precious’s baby blue shorts. He runs his hands down the expanse of milky skin, hungrily drinking the sight, squeezes the flesh around Koo’s thick thighs. He just can’t wait to ravish him. Eat him up. But he knows that won’t satisfy him. The omega wiggles his butt unconsciously, continuing to suck the thumb. Namjoon’s mouth salivates. Wishes it was his dick instead.
All in due time , he thinks.
His big hands caress the smooth skin of the omega, evokes unintentional whimpers from the baby. The breathy sounds only make the dick in his pants throb harder. Koo is lying on his back, half of his face buried in his soft pillow. He looks so soft and Namjoon can’t wait to ruin his baby. He can’t help but imagine him waking up, tummy overflowing with his daddy’s seeds. When the need to fuck the omega into submission grows, he finally pushes the oversized shirt up and looks hungrily down at the panties that his son is wearing. He barely holds back a groan.
“Look at you. My princess. Just asking to be fucked senseless,” he whispers, keeping his voice quiet. His hand reaches out to push the panties to the side, getting a view of his pretty pink hole. The cold air makes him clench and unclench around nothing. Some slick gushes out and the alpha leans down to take in the honey scent. His baby smells so divine. Namjoon spreads the omega’s legs apart and settles himself comfortably between his legs. He inches his tongue closer, and when he finally gets that heavenly taste on his mouth. He moans.
“Baby you taste so...good.” The tightness in his pants is getting uncomfortable. He wants to eat the baby out but maybe some other time. He needs to do what he came here to do. Before the medicine wears off or before someone else wakes up.
He pulls back to take off the panties, mindlessly throwing them somewhere on the bed. Sits up a little to pull his own sweatpants down, his impressively sized dick springs out; hard and aching. He’s so ready to just push it inside but no, he wants to see Koo’s facial expression as he rams into him, as he takes away his innocence. Carefully, he maneuvers the omega on his back. Koo’s lips are parted, little puffs of breath fill the otherwise silent room. He looks so fucking precious. And that makes the whole thing even more fun.
He reaches out to his hole again, manages to his fingers with the omega slick and then he rubs it over his dick. It shouldn’t hurt because he doesn’t want Koo to wake up.
“I’m gonna fuck you now baby,” the alpha tells him, pushing his legs impossibly further apart and lines himself with the hole. He holds his breath as he pushes in, inch by inch. After a painstakingly long while, he finally fills Koo with his big cock. Namjoon takes a shaky exhale. He’s been dying to this for a while and now finally it’s happening. He can’t help but laugh in sheer happiness.
He lifts his head to see Koo still perfectly asleep, although, a tint of red covers his cheeks. Like that little dumb omega has no clue what is going on. He smirks. “Gonna pound your slutty pussy.” He bottoms out with a muffled moan.
More and more slick spurts out of his greedy hole as Namjoon starts fucking into, he tries to keep his thrusts slow but the way that the omega’s hole is sucking him in, he can’t help it. He holds Koo’s hips to keep balanced and rams into him. Koo’s little pretty dick bounces with every thrust and Namjoon grins cheekily. He brings one hand to play with it, feeling a little playful.
He chuckles, giving it a few strokes. There’s precum on the tip and he coos. “Look at your little dick. Doesn’t even deserve to be called a dick, huh?”
He keeps fucking him but when he feels like he can’t keep his moans quiet, he grabs the panties and puts them into his mouth, just to keep himself quiet. Everything feels so dirty but Namjoon loves it.
Feeling a little mean, he slaps Koo’s pathetic cock and it flushes red. Koo briefly shivers, mouth parting to let out a soft whimper. His eyes are squeezed shut, breathing flushed. Namjoon likes to think it’s because he’s fucking him so well that even drugged, Koo can’t do anything but love it.
He loves my cock so much…stupid slut. Gonna breed him, fill him with my seeds.
His eyes dart down to see how the his big dick is disappearing inside the omega’s hole. He’s so tight, Namjoon feels his climax build up. There’s a visible bump on Koo’s stomach and he runs his hands over it, feeling so very proud of himself.
He bites on the panties harder, thrusts turning unstable the closer he feels to cumming. He pounds into the omega with the last of his energy and with a few more thrusts, he comes.
A loud moan pushes past his mouth, along with a little drool. He feels fucking fantastic. The tight hole continues to clench around his length. He spits the panties out and wipes the drool with the sleeves of his shirt.
The alpha fills the omega’s inside with his load, it’s almost never-ending. Koo’s stomach looks impossibly bloated with his cum and when he pulls out, he wipes the rest of his cum on the omega’s legs.
Namjoon does feel a little bad about not having Koo cum so he decides to be benevolent. He brings his long fingers and pushes inside the opening, he shoves his fingers inside, fucking all of the leaking cum back inside. The omega lets out a moan and that only encourages Namjoon. He uses three fingers in the beginning but soon he has his entire fist ramming into the hole. He takes in the beautiful view.
Namjoon had initially thought that fucking the omega once and for all would decrease his urges but after getting the taste he just wants more. He wants to take him and fuck him on every surface of the house. And he hopes that maybe next time, Koo will be awake for their little adventure.
With his other free hand, Namjoon play’s with Koo’s tiny dick, gives it a few strokes, and soon enough the omega’s back arches and he comes all over his stomach. Namjoon gathers some of it on his fingers and gives it a taste. Sure enough, even his cum tastes sweet. Feeling satisfied for now and tired from working all day at the office, Namjoon gets off the bed and pulls his pants back on.
Namjoon’s kind of torn between cleaning him up but decides he doesn’t want to, wants Koo to wake up with his bloated stomach. He still puts the panties back and shorts back on. Carefully covering the omega with the bedcover, he pushes his bangs aside and kisses him on the forehead.
“Good night, my little princess.”
Later when he’s showered in the guestroom bathroom to get rid of the sex smell, he gets onto his own bed.
“Did you tuck our son in sweetie?” his wife asks from beside him. He grumbles.
“Yes, of course, darling.” He just smirks unbeknownst to her.
