THANGYU KINKTOBER: size difference.

Work Text:

Nam-gyu’s still spread wide across the mattress, chest damp with sweat, lips parted around a series of slow pants. Pretty like this, Thanos thinks. Glassy-eyed and tired. He’s already been wrung out once, made obvious by the weak shudders that still wrack his chest where he’s hanging. Hanging, for some reason or another, with his head thrown back over the edge of the bed. 

The sight — Nam-gyu laid out and pliant, chin tipped high, throat exposed — makes Thanos’ dick twitch all over again. Instinctively, he drags a hand over his own length, watching Nam-gyu’s adam’s apple bob with each swallow. A new visual strikes him, then: that pretty little mouth open and stretched around each inch, spit-slick along the sides. Maybe not the same one, but an idea seems to come over Nam-gyu, too. His eyes flick from Thanos’ fingers up to his face. 

“What?” he asks — coos, with the way he says it, “you already wanna go again?”

A shake of his head. Not quite. No, there’s no need for all that readjusting. Nam-gyu’s just fine where he is. 

“Stay like that.” There’s a rasp to his voice; he’d be better off calling it quits, if they’re being realistic. Long day, sheets to be cleaned, never mind the cum streaking Nam-gyu’s thighs and stomach. It’s selfish forsure when he cups Nam-gyu’s chin, thumb pressing past his lips to pull them apart. Nam-gyu’s with it, though. Eager. Shines bright and unrestrained in his eyes. The last glimpse of them Thanos gets, anyway, guiding the tip towards Nam-gyu’s tongue.

It’s — different. A completely new angle. Upside-down, Nam-gyu’s tongue drags along the top of him. It’s good. Real fucking good, and they’re hardly anywhere past his swollen head. Nam-gyu makes a little sound and Thanos shakes with it. Too sensitive to be doing this so soon, but they’re already here. Leaning forward, he braces himself with a hand against the mattress, easing in nice and slow. Gives them both a chance to adjust to the position. He can feel Nam-gyu’s lashes fluttering against his skin, and he groans. 

“That’s it, baby,” he nods, reaching for Nam-gyu’s chest with his free hand. Spread first, then groping; reaching for a bud next and giving a gentle squeeze. When Nam-gyu whines around half his length, Thanos moans. “So good for me, you got it. Breathe through your nose.”

The view’s driving him nuts. The stretch, his cock curving up into the narrow column of Nam-gyu’s throat. Faintly, he can almost see it. Wonders if he rolls just a little deeper, inches a little further, he might be able to really

Nam-gyu gags, and Thanos pulls back. Leaves him with nothing but an inch or so sat behind his teeth while he sputters, spit spilling out of the corners of his mouth to coat his cheeks. “You okay?” he murmurs, thumb brushing over a nipple. Lazily, Nam-gyu nods, curling his tongue out. Message received. 

They try again. Thanos positions a little closer this time, and sinks in with ease. Nam-gyu’s jaw sits slack, leaving him with a slight graze of teeth; Thanos hisses. As his hips move, his knees rest against the edge of the mattress, cock swallowed up by pure wet and warmth. Fuck yeah.

His own head is tilted down, watching. Focused on Nam-gyu’s mouth first, then the swell in his throat when he makes it in deep enough. This time, Nam-gyu’s got it. Hollows out his cheeks and sucks just like he would any other time, reaching up above his head to curl his nails into Thanos’ thighs. Again, he groans, easing back only to push in even further this time. His cock twitches, and he lifts off of Nam-gyu’s chest to brush fingers over the bulge in his throat. 

“You feel that?” Thanos asks, “God, I wish you could see this. You look so fucking hot.”

The praise encourages Nam-gyu further, of course. He hums, back arching off the bed, and Thanos can see his poor girl’s cock leaking where it rests untouched, pitiful. No worries, Thanos won’t let him suffer for long. Just — wants to indulge in this, is all. Never seen anything like it before; it’s intoxicating. Shallow thrusts, Nam-gyu’s nose brushing his taint, he’s anchored like this. They both are. Nam-gyu pulls Thanos in close, that wordless urging of come on, I can take it.

That part is nothing new. Thanos does just that, fingers pressed into the hinge of Nam-gyu’s jaw. “Taking me so well.” Every time Nam-gyu tries to swallow around him, Thanos can feel and see the muscles in his throat draw tight. With it, strangled and pitched noises spilling around him, reverberating all the way up Thanos’ spine. “So pretty, you know. My beautiful girl.”

Nam-gyu responds in kind. Rolls his own hips into the air, tonguing back and forth over every bit he can reach. Only then does Thanos drag his cock all the way out, panting, taking with him all the spit stringing from Nam-gyu’s lips to the tip. 

“Come on,” Nam-gyu says, hoarse, eyes wide and wet with slowly spilling tears. “Give it to me.”

How is Thanos meant to say no?

When he pushes back in, there’s no slow ease this time. It ends with his pelvis pressed to Nam-gyu’s chin, the bulge in his throat at its very deepest. Thanos grinds just like that, babbling — admittedly weak — strings of praise. Losing himself in it, honest. Helpless rutting, caught up still in the mere sight. Nam-gyu taking it, taking all of him, and without any struggle. Practiced. It makes Thanos’ skin burn hot. Nam-gyu, so fucking cock-hungry that this is nothing. Something he wants, even; buries his fingers in tight against Thanos’ legs and refuses to let him go. 

All of that heat sneaks up further and sits heavy in Thanos’ gut. His fingers lift, pressing into Nam-gyu’s hollowed cheeks, making everything tighter. That’s it for him. Thanos’ hips roll once, twice, before he comes down Nam-gyu’s throat with a choppy little cry, fucking himself through every bit of it. Nam-gyu moans, whines, groans through it all, pushing his face further into Thanos until each drop is swallowed.

Pulling back, Thanos stands, staring down at Nam-gyu through half-lidded eyes. Caught in the haze, definitely, but when Nam-gyu looks back up at him through those pink-rimmed eyes, lower lip swollen and pulled between his teeth — is he really supposed to just do nothing? 

First, he leans down, catching Nam-gyu’s lips with his own, tasting. Salt, spit, himself. Spiderman kiss; how romantic. Not particularly easy to keep up with, though, and doesn’t last long. Nam-gyu pulls back to catch his breath, while Thanos takes the time to crawl back into bed. Poor, poor, Nam-gyu: flushed all over, trembling. Needs to be taken care of. Needs to feel, too. 

“Hey.” Thanos lays on his back, parallel to Nam-gyu. “Your turn.”

Smooth. He thinks so, anyway, but Nam-gyu only raises an eyebrow. “No way,” he says, shaking his head. “I can’t stand right now.”

Fair enough. Thanos hadn’t really considered it, but given the shake in Nam-gyu’s legs, he probably should have. Oh well, plan B. Instead of sprawling half-off the edge, Thanos rests back against the pillows, reaching out for Nam-gyu’s hand. “You can sit on my face.”

Yeah, that’s not a problem. Nam-gyu wastes no time in situating himself, hole to tongue, and Thanos gets to work. Knows good and well what Nam-gyu needs. Finds his heart thrumming rapid behind his ribs when Nam-gyu just takes. Sits down full weight, one hand laced with Thanos’ own while the other holds steady against his chest. 

Thanos groans into him, tongue pressed flat against the rim, flicking. With it Nam-gyu exhales slow, grinding back, urging him deeper — as much as Thanos loves to play, he’s not going to keep his baby waiting now. Not after how good he’s been. It’s the least he can do, sinking his tongue in, reaching around to take Nam-gyu’s slick cock in his fingers. He shivers in response, and meets Thanos halfway; fucks his face, even. Gives Thanos exactly what he wants.

Needless to say, it’s not long before Nam-gyu’s clenching around his tongue, thighs pressed tight where they bracket Thanos’ face. Who needs air? Definitely not him, not when he’s got Nam-gyu stretched out his tongue and coming apart in his arms. He collapses soon after, squeezing Thanos’ hand and rolling over so they’re laid out face to face. Like this, he can brush Nam-gyu’s hair back behind his ear, lean in and meet his smile with a sweet kiss. “I love you,” he says, nose brushing along Nam-gyu’s cheek. “Had a good time?”

Trailing his palm along the length of Thanos’ torso, Nam-gyu nods. “I love you.” Easy sentiment, always echoed. His fingers stop right in the center of Thanos’ chest, massaging, head dipping to rest in the crook of his neck. “Think you can go again?”

God. Now? Thanos presses his lips into a thin line, considering. Can he? Yeah. Fuck yeah. 

“How do you want me?” he asks, pulling back to catch the twinkle in Nam-gyu’s eye.

Long night ahead.
