Chapter Text
Jimin knows the train at rush hour is going to be packed, so when he hears the call that it's pulling up at the platform, he's already standing, ready to go. It's not like he's ever going to get a seat at this time of the evening, but if he's lucky he can snag a spot standing near a door, and he's got his hand on the bar when the train pulls into the station.
He's not the first person onto the train, but he's one of the first, and he's relieved to see a spot at the end of the car, right next to a pole. He snags it, shoving his backpack down in the gap between his feet and the pole, and he's holding the pole with both hands when the train starts up again, the momentum making his body sway into the person crammed next to him. The train car is louder than usual, shaking and lurching in a way that only a train in dire need of repair would.
Great, the already unpleasant ride is going to be that much worse today. The irregular shaking of the train car causes his body to press and rub into the huge muscular man standing behind him.
He can feel his entire body tense as his face heats up. It's like the guy is made out of granite, his body unyielding, and Jimin's trying to figure out what the fuck he's supposed to do. But the train is moving his body is into the hard body behind him. The bumps and vibrations of the train causing his ass to jiggle and bounce against the man's thighs.
"S-sorry,” he stammers, trying to lean forward, away from the man.
He manages to move the top half of his body away but it just makes him bend back into him on his lower half, and the man is so big that his body is practically cocooning Jimin, and there's no way for him to move away without pushing bunch of people. So he's stuck there, pressed against the guy, feeling every single movement of the train against his ass. He’s practically assaulted the guy.
"It's all good.”
The deep rumble of his voice sends a shiver down Jimin's spine and his mouth goes dry. Fuck. If he stays like this, his ass is going to keep rubbing and bouncing against the man, making him look like a total pervert. Jimin tries pressing himself flush with the pole, from his face to his groin. It’s uncomfortable but at least it’s given a sliver of room between him and the man. The bouncing and vibrating feel so much stronger pressing against the metal pole. One particularly strong jerk has him almost losing his footing when his backpack shifts between his feet. He falls back into the strong chest of the man behind him before clinging back to the pole, almost smashing his face into it.
Then the guy moves. Jimin thinks he's about to get shoved or punched, honestly he deserves it for practically grinding on the guy. But instead of shoving him away, the guy grabs the pole above his head and leans forward, his huge body curving over Jimin's smaller frame. His chest presses against Jimin's back. He's caged in tightly between the pole and the man. The heat of his body is scorching, seeping through Jimin's suit. Jimin stares at the thick bulging arm and the hand wrapped around the pole above of him.
How was it possible for a hand to be attractive?
"You seem uncomfortable,” the guy rumbles in his ear, startling him, "Just try to relax and enjoy the ride. I'll keep you steady."
Jimin can't help the squeak that comes out of his mouth. He catches a glimpse of the man. Holy fuck. His dark shaggy hair and sharp jaw belong on the cover of magazines. He doesn't know what to say, so he doesn't say anything, and it's a good thing too, because his words are trapped in his throat when the train jolts and he’s slammed with the man’s lower body and almost falls again.
“I got you.”
The guy wraps his arm around Jimin's hip, pulling his butt flush against the man’s groin. His legs are practically jelly at the feel of the man’s hard hot body. Jimin is sure he's blushing bright red. He can't believe this is happening.
"Relax,” the guy says, his lips brushing against the shell of Jimin's ear, "I won't let you fall."
It's like the universe is taunting him.
The guy is huge, and Jimin is so small, and it's so fucking easy for him to pull him back and press him into the hard line of his body. Jimin can feel the curve of his biceps around him, and the heat of his breath, and the firm pressure of what he’s almost positive is his dick. His head is spinning.
His own cock is throbbing and it's so fucking wrong, but the man's huge body is holding him tight. He's being crushed, can't escape, his heart is pounding out of his chest. He feels helpless. Like he’s totally at the mercy of the man.
The train jolts again, and the man's hips grind against him, and he can feel the man's erection pressing into him, he’s sure of it, and he lets out a soft gasp.
The man's fingers stroke over his belly, and his hips rock, and the movement is so subtle that no one would notice it. But Jimin does. Jimin notices, and his entire body tenses and shivers. And he can't help the way his own hips shift and grind back into the guy. He can't help it. It's just the way the train is moving.
The man lets out a quiet groan, and Jimin can't hold back his own whimper.
"Shh,” the man says, his voice low and husky, "I've got you."
And it's like a switch has been flipped. Jimin melts against him, his body relaxing and molding against him. And then the guy starts sway against him, moving both their bodies. His hips moving slow and steady, grinding against Jimin's ass. The slow rock of his hips in combination with the shake and vibration of the train car has him aching.
"Fuck,” the man mutters.
Jimin whines, the sound slipping past his lips, and the man's hand slides over Jimin’s erection. Jimin's mind is going blank as the pleasure and embarrassment overwhelm. His whole world narrows down to the feeling of the man's body, and his fingers, and the hot press of his erection.
"Oh fuck,” Jimin gasps, his mouth hanging open as he stares up at the man's thick bicep, and the way his suit jacket strains over his huge bulging muscles.
"So cute,” the man growls, his breath hot on Jimin's ear, "Be good for me. Just keep your pretty mouth quiet."
Jimin's entire body shudders. The man's hips are rolling into him, his cock grinding against his ass, and it's so fucking dirty, and Jimin is going crazy. He wants more. He needs it.
"Oh fuck,” he moans, his head lolling back onto the guy's shoulder, "Please."
"Quiet,” the man growls.
Jimin bites his lip, his teeth sinking into the flesh as he struggles to keep silent.
"Such a good boy."
His words make Jimin's stomach clench and his cock throb.
"Such a hungry little slut, trying to ride my cock like this."
And Jimin can't help the whimper that escapes his lips.
"That's it,” the man groans, "Keep your sexy little noises quiet."
Jimin can’t. He can't help himself. The man's cock feels huge, and the way he's grinding against him is driving Jimin insane. He chances a look down and sees the huge wet head of a cock peeking out from between his legs. Fuck. The guy is fucking his thighs, rubbing against Jimin’s most sensitive spots. And the more Jimin tries to hold back his moans and whimpers, the more the man rubs and grinds.
"So fucking cute,” the man groans, "I bet you're going to look even cuter when you cum."
Jimin can feel his stomach clench. His cock is throbbing and aching, and his orgasm is building.
"Gonna cum in your pretty panties, aren't you?"
The man's hand moves down, sliding over Jimin's crotch, and grabbing his own cock, pulling it up hard against Jimin as he thrusts. The sudden pressure against his aching cock is too much. He bites his lip hard enough to bruise and his back arches as he he cums in his pants.
"Yeah,” the man groans, palming the wet spot in Jimin’s pants, "You like that don't you? Like getting pounded by a stranger on the train like a desperate little whore.”
"Oh fuck,” Jimin gasps, his hands wrapping around the man's arm, "Oh fuck."
The man laughs. A low dark sound.
"So perfect."
The train starts to slow down and the man steps away, his dick slipping out from between Jimin's legs, and Jimin misses his warmth. Misses the feeling of being held and pressed against him. He glances over his shoulder, his face flushed and his eyes wide, and the man is looking at him with a wicked smile.
“See you tomorrow, Jimin.”
And then the train doors are opening, and the man is walking away, and Jimin is left standing there, his mind reeling.
How the hell does the guy know his name?
