"We have to be quick, okay?" Seokjin whispers, his voice barely loud enough for Jeongguk to hear.
Jeongguk rolls his hips down, a hand tangled in Seokjin's hair while the other is wrapped tight around his leaking cock. "Mm."
Seokjin tsks, fingers moving at a slower pace than he'd like them to. "Gukk, I mean it. We can't hog the bathroom forever."
Jeongguk ignores him, throwing his head back when Seokjin's crooked fingers find his prostate and push against it. Seokjin watches him with hunger and lust burning through him, already anticipating the moment Jeongguk will slide down his girth and take all of him in one quick movement.
Seokjin reaches up with his other hand and tweaks Jeongguk's nipples through his t-shirt, smiling to himself when Jeongguk bites his lip to keep from groaning. "Gukk-ah. Do you understand?"
Jeongguk swivels his hips and nods, hair flopping into his face. "Yes, hyung. Christ, please aren't three fingers enough?"
"You know they're not," Seokjin murmurs, eyes on his three fingers that are buried deep within the younger man on his lap.
The toilet seat he's sat on is far from comfortable, but the bulge in his pants is more uncomfortable than anything Seokjin can bear at the moment which is what led them to the airplane's bathroom. Jeongguk had already been stretched by the buttplug he'd worked into himself that morning before leaving for the airportーhis favorite one, the bunny tail oneーso it'd been far too easy to pull the plug out and press two of his fingers into him. Still, Seokjin thanks Jeongguk's libido for buying travel-sized lube and sticking it into the pocket of his jeans.
Jeongguk gasps out heavily when Seokjin spreads all three of his fingers apart inside him. Seokjin marvels at the way Jeongguk's walls seem to clamp down on him.
"Hyung, don't tease, fuck," Jeongguk breathes out above him, his voice hoarse and low.
Seokjin smiles again, slowly drawing his fingers out. "Don't be so loud. You want to get caught?"
Jeongguk stills in his lap, eyes wide and Seokjin's smile morphs into a smirk.
"You do, don't you? Want everyone to see you taking your hyung's dick so nicely? You want everyone to know you're my slut, don't you?" Seokjin murmurs between them, leaning back until his back is pressed against the plastic of the toilet. "Why don't you show me how much you want my cock, huh?"
Jeongguk shivers with Seokjin's words, numbly pawing at the elder's zipper as soon as he's done speaking. Seokjin almost wants to laugh at how easily Jeongguk manages to spring his cock free from the tight restraint of his jeans, but he covers it with a smirk instead and grabs the tiny bottle of lube, squirting some more onto four of his fingers. Jeongguk makes to sink down on Seokjin's newly released cock, but Seokjin grabs his hips and tsks at the younger man.
"Gukk, you know the rule. Four fingers. Nothing less. Be patient," Seokjin says.
Jeongguk whines, a noise high and needy and Seokjin slaps his thigh, silencing him.
"I could always leave you in here with only your fingers. Do you want that?" Seokjin asks, his voice low with a little dark edge to it.
"No," Jeongguk whispers, biting his lip as he stares at Seokjin with his big, doe eyes. "Please, hyung, it hurーah!"
Seokjin buries his slicked fingers into the younger, interrupting most of what he was going to say. Jeongguk is tight around him, but as Seokjin steadily works him open, the younger relaxes around him, his hole fluttering with the pressure. Jeongguk sighs then, sagging into the elder's lap as Seokjin finally scissors him completely open and taps his thigh gently, wordlessly telling the younger to lift his hips up.
Jeongguk does as he's told and soon the head of Seokjin's thick cock is at his entrance, the pressure familiar enough to Jeongguk after all the times they've fooled around so far. Seokjin presses in then, teeth clenched when Jeongguk hisses as he sinks down, thighs shaking with the effort. Jeongguk presses his face into Seokjin's shoulder as he takes the elder to the hilt, his body adjusting to the sudden intrusion and soon Seokjin is kicking his hips up experimentally. Jeongguk bites into the elder's collarbone then, leaving a dark mark that will take a lot of makeup to cover up later.
"We don't have a lot of time, Gukk-ah. You okay?" Seokjin asks, brows pinched together in concentration.
Jeongguk nods helplessly, his sweaty hair falling into his face. "Yes. God, yes. Please, justーmove."
The bathroom is tiny and crapped and Seokjin knows they're both going to have cramps for the rest of the trip, but he considers it worth it when he grips Jeongguk's waist and fucks up into him, the blessed heat of Jeongguk's ass welcoming him. There's a knock on the door, but all Seokjin has to say is a simple "occupied" before the person is moving away and Jeongguk’s wriggling in his lap again, timidly working his hips down to fuck himself on Seokjin's cock.
"You're so beautiful, Gukk-ah," Seokjin mutters in between his thrusts, eyes only on Jeongguk's face as the younger takes him.
A blush rises to blanket Jeongguk's cheeks, but that's the only indication Jeongguk gives about hearing Seokjin's praise. Seokjin readjusts his claim on the younger man's hips and fucks up into him with fervor, suddenly desperate to come as another knock sounds out in the tiny airplane bathroom.
"Occupied!" Seokjin yells out, hoping with all his might that they can't hear the tiny gasps and whines Jeongguk is letting out from bouncing on his cock.
This person moves away as well but Seokjin isn't given the time to take a breath of relief because suddenly the plane is hitting turbulence and Jeongguk is clinging to him, impaling himself on Seokjin's cock as Seokjin scrambles to grab ahold of the wall.
"Fuck!" Jeongguk curses under his breath, gasping into Seokjin's neck. "Hyung, fuck, I don't remember you being this big."
"Well, no need to stroke my ego, Gukk-ah," Seokjin says with a smirk, almost laughing when Jeongguk groans into his chest before moving his hips again, uncaring of the turbulence the plane is going through.
Seokjin's hips rise to meet Jeongguk's and their sloppy rhythm is set, pushing them both towards the orgasm they've been craving ever since they woke up this morning.
Jeongguk is the first to come, with a whine being the only warning Seokjin gets before he blows his load, globs of thick white falling over Jeongguk's knuckles between them. Seokjin keeps fucking into Jeongguk, groaning under his breath when Jeongguk clamps down on him, the tight heat of his ass pushing Seokjin over the edge. His orgasm takes over and Seokjin's thighs shake with the force of it all, cumming deep inside the younger.
They sit on the toilet seat for a little while longer, basking in the glow of their post-orgasms, kissing from time to time until they're wrenched out of their moment by another knock.
"Occupied!" Jeongguk yells out, rolling his eyes when the person grumbles something unintelligible in response before walking away.
They exchange matching grins then, Seokjin tipping forward to take Jeongguk's hand and hold it up to his face, examining it closely before he slips a finger into his mouth and sucks. Jeongguk's eyes widen, his face flushing, but he doesn't pull away and Seokjin takes that as an invitation to lick the younger's hand clean of his own release.
When they do manage to get back into their seats, Seokjin knows he isn't imagining it when their entire row looks at them knowingly, judgment in their gazes. Jeongguk flushes a pretty, dusky pink but Seokjin only laughs and kisses him on the mouth, uncaring of who's giving them the evil eye.
