Work Text:
Seokmin had always been into tall men. The taller the better. He loved having to crane his neck to be able to see his partner, enjoyed the uncomfortable stretch.
So when he met Kim Mingyu, it was like seeing someone with all the ideals he wanted (and needed):
Likes to clean (Seokmin is a messy bitch).
Buff enough to throw around a grown man. (Just thinking about it made his stomach feel hot).
His friend informed him Mingyu was also a service top. (Nothing like being serviced by a sexy hunk).
A stupidly big alpha dick (also according to his friend).
And of course, deliciously tall.
It had taken everything in Seokmin to not climb the man immediately. He managed to keep his hands off until the third date! Which is very good if you know Lee Seokmin and his thirst for tall, sexy men.
Mingyu was sweet. A romanticist like himself, but he wasn’t hard to ask. It only took a smile to convince the tall man to come back to his small apartment, just a flutter of his eyelashes to get himself pushed down into bed, naked as the day he was born and so much slick pouring out of hole.
Seokmin had asked him to be rough. To manhandle him. Mingyu provided.
Pushing Seokmin onto his stomach, strong, rough hands pushing his hips up.
“Spread your legs wider,” Mingyu said, his lisp oddly cute for the scenario they were in. Seokmin listened, squeaking when his ass-cheeks were parted and his fluttering hole was revealed to the cold air.
“You’re leaking,” Mingyu sounded incredulous. “Already gaping. Did you- Have you-“
“Fucked myself on a dildo before our date yeah, didn’t want to be too horny during the movie.” Seokmin spoke about it casually, not embarrassed he had admitted about being crazy horny for Mingyu.
“I see.”
“Oh- Fuck!” Seokmin hadn’t expected a thick tongue lick a stripe over his slick covered hole, but he loved it. Loud whimpers falling out of him as the tongue enthusiastically teased the sphincter, pushing in after several agonising seconds of teasing. He didn’t need to be loosened up, but he was not one to say not to being eaten out.
“God!” Seokmin buried his head in one of his pillows, feeling an obscene amount of slick push out of him from Mingyu’s administrations. He wanted to look back, see how wet Mingyu’s face must be, but the angle was too awkward so he could only imagine as the diligent tongue fucked him.
His cock twitching, begging for touch, but he ignored it. He found purchase in the soft sheets, pushing his head up again, mouth open as he let out loud sounds he couldn’t stop. “Min- Please- I need-“
“Okay. If you’re ready? You sure you don’t want more prep?”
“Yes oh my fucking god, I’m not fragile!”
Mingyu laughed, a pleasant sound. “Okay.” He manhandled Seokmin again, practically seating him onto his wide thighs. Seokmin noticed how the other was sitting on his knees, but couldn’t see much else, not with his back flush against the chest. “I’ll fuck you like this.” A few more seconds, hands moving around, then something big breached his entrance.
It was a slow slide, Mingyu being gentle despite Seokmin’s earlier request.
“Yeah, definitely bigger than the dildo I- Oh, fuck! God!”
“You okay?” Mingyu froze, his hands on Seokmin’s soft, plush hips holding him steady.
“Yes, god. Please just-“ Seokmin slammed himself down, howling at the way his walls stretched around the thick girth. Truly a stupidly thick alpha cock.
“Why did you-“
Mingyu had no chance to finish his sentence as Seokmin’s cock shot out seed, accompanied by a loud curse.
“Well-“
“No, keep going. I can take it. I want it.” Even with his softening cock and his whole body shaking, he knew it wouldn’t be a problem. He was no stranger to overstimulation.
“You sure? I’m surprised you already came.”
“Yes god, just- Do I have to beg?”
Mingyu breathed in sharply. “... Maybe?”
Of course. Seokmin would have snickered and maybe teased the alpha a little, if he wasn’t so incredibly horny. “Please fuck me with your dumb thick alpha cock! Fill me breed me whatever just fuck me! Please!”
Mingyu hummed, hands tightening their hold on Seokmin’s hips. “Okay.” He kissed Seokmin’s cheek, making the omega aware that their height difference was enough for Mingyu to easily rest his chin on Seokmin’s shoulder, despite the omega sitting on his lap.
His spent cock twitched due to the knowledge.
“Gonna fill you up,” Mingyu promised. “Gonna give you my knot.”
Seokmin whined and lolled his head backwards, letting Mingyu take over completely. Mingyu lifted himself, forcing Seokmin to lean on his own parted knees, thighs no doubt going to burn soon.
Mingyu started, pace brutal. One hand on Seokmin’s hip and the other around his waist and fingers teasing a nipple. His mouth was by Seokmin’s ears, breath hot and harsh.
Each snap of the hips caused Seokmin to yell out, both overly sensitive and intensely horny. His dick was already hardening, pre-come leaking like crazy.
“Fuck, look at you,” Mingyu groaned into his ear, the hand teasing a nipple sliding downwards. Seokmin followed it with his gaze, eyes widening as he saw what Mingyu’s thick fingers were caressing.
Each thrust reached so deep his stomach was bulging. The knowledge caused another obscene amount of slick to push out of his hole, his already wet thighs practically soaked.
“Fuck, you’re so good. You’re made to take my cock.”
“Yes!” Seokmin pushed away the hand on his stomach, wanting to feel it himself. His dick jumping each time he felt the stomach bulge.
The room was covered in their heavy scents, their sounds filling the space.
Minutes went by, Mingyu not once slowing down and Seokmin was so hard he was crying, tears streaming down his cheeks in a needy wish to come.
“Only when my knot is in you.”
He had promised.
“Alphaalphalpa-“ He was chanting, head lolled back on the warm shoulder, Mingyu grunting and moaning in his ear.
He felt it. Felt the cock splitting him open grow at the tip, felt it expand and push agains his walls. He screamed, feeling fuller than he had ever been. Feeling like he was being torn apart and it was all so perfect.
He came as he felt the knot settle, hearing the sharp gasp from Mingyu as he pushed in impossibly deep. Seokmin swore he had never orgasmed as hard as he did then, vision turning black and spilling all over the sheets. He was completely out of it.
As he came to, he had been placed down on the bed, Mingyu spooning him and his big cock still deep inside him.
Seokmin whined, hand caressing the bulge on his stomach.
“You okay?” Mingyu was hoarse, sounding as exhausted as Seokmin felt. He placed gentle kisses on the omega’s nape.
“Feeling amazing. Full. Never been this full before.” And he would be even fuller, considering the amount of seed he knew an alpha knot would continuously give until it deflated. “I really hope you want to take me on a fourth date.”
Mingyu laughed at that, an almost giggle. “Of course. I was even hoping we could officially be boyfriends now? Or maybe that’s too soon? I just really like you-“
“Yes. I would like that.”
Mingyu laughed again, a happy sound, and pressed even more wet, sloppy kisses onto his nape and shoulder.
Seokmin giggled at the attention.
There was no way in hell he would let go of such a sexy tall man with a perfectly big cock.
