Work Text:
The train rumbles under your feet as you walk down the narrow walkway of the big, steam powered vehicle. Rengoku was behind you, a hand gently resting on your waist, easing you as the train shook and jerked. Walking past seats and sleeping passengers, you finally made it to your seat. Rengoku helped you sit yourself down and then sat next to you, resting a hand on your thigh, offering a small squeeze of your plush legs. He smiled, and you smiled back, trying to hide your nervousness. This was a big mission, dangerous, and you had a strong distaste for crowded, tight spaces.
You were waiting for three other demon slayers to join you, younger and newer, but still great fighters. Rengoku assured you over and over again that, with the power of the five of you, this mission would be easy. You wanted to believe him, you really did, but it was so hard to calm down when even your seats were shaking and rumbling under you.
Rengoku pulled a small box from a hidden pocket. He could carry almost anything in his uniform and lunch was an essential for him. He gently opened the box, revealing rice buns and two sets of chopsticks. He handed you one and you accepted, clicking the two sticks together a bit before gently taking a triangle of rice and carefully taking it into your mouth. You smiled as you chewed, a silent thank you and he returned the gesture as he slowly removed his hand from your thigh, turning his attention to the food in front of him.
"Mm.. Delicious," Rengokus says to himself, a smile spread across his face and his eyes closed in content. You can't help but giggle and he laughs quietly along with you, keeping his eyes closed. "Not as delicious as you, though" he opens his eyes and stares at you through long, thick lashes, a seductive smirk spread across his features. You feel your blood rush to your face, painting your cheeks red.
"Kyojuro!" You laugh nervously, glancing around. The passengers hadn't stirred, no one heard you. You look away, face embarrassingly red. You knew Rengoku could be playful, but you didn't think he would suggest that while on a mission.
A faint click and clack snapped you out of your thoughts. Rengoku had closed his lunchbox and had put it back into his hidden pocket. You watch as he does this and his orange eyes lock with yours, lust deep within his irises. He reaches a hand back over to your thigh and he gently caresses your soft, plush leg. You gasp quietly as his hand trails up your leg, his fingers brushing against the damp circle on your underwear and slowly snaking underneath your skirt. Two of his digits rub against your clothed lips and his thumb takes charge of your clit, rubbing circles over and around it. You bite your lower lip, holding back your moans and whimpers and your hips start to rut up into Rengokus' hand. Why was this turning you on? You should be ashamed of yourself, doing this in public. Kyojuro inches his face towards your ear and whispers. "You know the safe word, doll." His digits rubbed harder against your folds, the friction building pleasure in your abdomen and you clasp a hand over your mouth, muffling the small whimpers that escaped your quivering lips.
His hand pulls back, leaving your cunt throbbing in desperation, silently pleading for attention. Your eyes widen and you look at your lover. His lips are curved into a smirk and he leans back into his chair as he spreads his legs and places his hands on the armrests. "I need to use the bathroom, I'll be back" he flashes you a wink before sitting up and heading down the narrow aisle and he disappears into the restroom.
Fucking bastard. Horny bastard. A string of curses aimed at your lover flow through your mind and before you know it, you're in front of the bathroom door. You sigh, maybe you're the horny bastard. You knock, gently, on the frail door. Muffled shuffling ensues and the door opens slightly, your boyfriend's big eyes peeking through the door. He opens it further, just enough space for you to sneak your way in.
The restroom is a tight squeeze and Rengoku and you are close together, your back to him. Your plush ass rubs against his groin as you turn around to face him. He bites his lip and clenches his first, feeling his blood rush to his cock. You look up at him, feeling the dampness between your legs grow. He looks down at you, feeling his pants becoming tighter and tighter by the second.
Not a second later, your mouths are intertwined and his hands grope and squeeze at your ass and tit. A leg wrapped around his waist and your back pressed against the wall, Rengoku's boner grinds against your eager cunt. Your clit throbs, begging for stimulation and your walls painfully clench around nothing. His tongue explores every inch of your mouth and he pulls back with a bite of your lower lip, eliciting a whimper from you. His hand leaves your tit and he makes haste of pulling your skirt down and unbuttoning your top, freeing your boobs from their confines.
He groans, the sight of the plush mounds of skin on your chest turning him on even more. "God I fucking love your tits," he exhales before his mouth lands in between the two, marking the skin between them with his love bites. A hand snakes up from your stomach to twist your nipple as his lips make their way to the other, biting the sensitive bud before enveloping it in his mouth. A wave of pain strikes through your spine at the sensation, but nonetheless, your back arches and a moan escapes your swollen lips. You grab at his bright hair, undoing his half-up bun. Teeth meet the sensitive plush of skin around your nipple and your hand clasps over your mouth to muffle a moan. Kyojuro's long fingers slip under your underwear, spreading the petals of your heat out. Slowly, he pushes his middle finger inside of your dripping pussy.
"M-mm!" A whimper escapes your lips and your back arches further as his long finger starts thrusting up inside of you. Joined by a second digit, the two curl up into your sweet spot and start thrusting rhythmically. You almost scream as you throw your head back in pleasure, hips starting to ride Rengoku's fingers. Your clit is stimulated at the same rhythm as your gummy walls, and the knot in your stomach grows dramatically. Whimpers escape your lips and your breathing becomes more labored as you reach your high, the knot getting tighter and tighter. He pulls back from your tit, the skin now red and swollen and he adds a third finger. The stretch stings, but your walls beckon him further inside, causing him to hiss.
"Mm, baby you're tight, so fuckin' tight for me," he praises, curling his fingers more and thrusting harder into you. Your arousal covers the entirety of your inner thighs and, besides the rumbling of the train, the only thing heard is the sound of Rengoku's fingers loudly slipping in and out of your cunt. "Pretty pussy's so wet, so so wet for me" he growls as his eyes are fixated on his long, thick fingers disappearing inside of you and coming back out covered in slick.
"A-ah, Kyo- Kyo 'm gonna cum," you moan, your voice muffled by your hand as you claw at your cheeks. The knot in your stomach turns into a white, hot flame, violently growing with each thrust of his fingers, each circle over your sensitive clit, and each tug and twist of your nipple.
He's knuckle deep in you now and his three fingers curl and your vision goes blurry, covered in stars and dots that dance in front of you as the tension in your abdomen finally snaps. Your hips move on their own now, bucking and thrusting yourself on his fingers as he continues to rub circles on your clit and curl his fingers inside you. You tug at his hair, eliciting a moan from him and his fingers slow inside of you. His fingers free your now overused nipple and he slowly pulls his fingers out of your sensitive cunt. You whimper at the emptiness and your grip on his hair loosens as your knees go weak. He catches you, by the plush of your ass and he carries you above him, tits in his face. He presses a kiss to the purpled skin between your boobs before pushing you against the wall, one hand focusing on unbuttoning his shirt and freeing his cock from his pants.
You hear it. The weight of it smack against his abdomen, you can almost picture his angry, red tip, slick with precum and his veiny, thick shaft. You look down and it's somehow bigger than you imagined. You see the veins grow and the shaft twitch as it slowly inches closer and closer to your entrance. You gasp as the tip slips inside, your walls instantly clenching around it and pulling it further inside.
"A-ah fuck," you whimper as he slips his shaft in to your sopping pussy. "Kyojuro, 's big," you grab at his hair again, the remnants of his bun long gone.
He hums in response, inching further and further into you, stretching your walls slowly. "S-so fucking tight for me, pussy's all mine," he moans into one of your tits.
"S-slow, slower," you beg, the stretch becoming painfully sweet. "H-hurts."
And he does as he's told, halting to a stop, barely halfway inside you. His cock twitches inside of you and you can feel his veins pumping more and more, somehow making him harder. "Mm, tell me when to keep going, doll," he musters, using every ounce of self control to not thrust himself balls deep into your wet cunt and make you scream.
With the rumbling of the train bouncing you up and down slightly, the stretch is almost unbearable, and Kyojuro notices this. He takes a hold of your ass, making you lean over his shoulder and you whimper at the movement. Slowly, and at a steady pace, you slide down his cock, both of you moaning each time another inch slips in. He holds back his moans by biting your shoulder and you claw at his back.
"M-mm, Kyo," you mutter. "Kyo just go, t-too horny. Need, need your cock please please," you exhale wrapping your legs tightly around his waist.
And suddenly, his balls smack your ass and your walls clench and stretch at the same time, a painfully pleasurable juxtaposition. You almost scream, but you manage to clasp a hand over your mouth.
"Baby," Rengoku coos. "I won't go unless you let me hear you." You can hear the smirk in his voice and your eyes widen.
"People will hear us, Kyo," you mutter, lip quivering from the slow stretch of your cunt.
"The train's loud, everyone's asleep anyways." He lifts you up on his cock by your ass, making his cock partially slip out of you. The emptiness is painful. "Let me hear my doll scream my name."
You know you shouldn't, you know you'll probably regret it. But the heartbeat in your clit is overwhelming, and you slowly remove your hand from your face, letting your digits relax on his back, ready to mark his skin with your nails.
"Such a good girl," Kyojuro plants a kiss on your cheek before he slams you down on his cock.
The wind is almost knocked out of you and your scream catches you off guard. He's thrusting into you, making you bounce up and down violently on his dick. His pace is steady, and with the help of gravity, his cock is going harder, deeper than ever before. It's painful, it makes your eyes well up with tears. But you're still a moaning, screaming mess, whimpering his name and curses.
"O-o-oh my God- Rengoku! A-ah," the bouncing of your entire body makes it hard to speak and soon, sobs join the chorus of your moans and praises. "F-uu-ck! So good, s-so..!"
His moans are low and powerful, muffling them into your tits as he rams his dick further and further into your cunt. He's aiming for your sweet spots, but holding you and fucking you proved to be more difficult than he thought. So, with a slam of your pussy to the base of his cock, he stops.
You're cock drunk, still mumbling curses and moaning while you sit idly in Kyojuro's arms. You don't even realize you've been set on the tiny sink until the cold surface stings your bare ass. You shiver at the feeling and look up at Rengoku. With a hand to your shoulder, he pushes you back, making you lean against the wall, back against the mirror.
Rengoku rests a hand on the mirror behind you, caging you between him and the corner of the room. You adjust your ass, trying to get comfortable on the tiny sink, and your hand rests on the faucet for support. Your legs are shaking and your breathing is an unsteady song of moans and whimpers. Rengoku's other hand rests on your hip, gripping on your skin as he resumes with a steady, powerful pace.
You can't help but let out a long moan, your pussy sensitive from your previous orgasm. "H-hard- Ah-!" your tits bounce as he rams harder, deeper inside of you. You can see his cock disappear into you, then quickly diving back into your pussy.
Rengoku's kissing your cervix with every thrust. Your moans only grow louder when a hand reaches down to your cunt and starts playing with your clit. Your back arches, you claw at his arms and you scream praises and curses, not caring that other passengers might hear you.
Soon, that familiar sensation returns to your stomach and your world starts spinning. "C-cum, cummin'" you manage to say, distracted by your pleasure.
"C-cum on my cock, doll," Kyojuro moans, maintaining his pace even as he reaches his peak.
And you do. You cum around his dick, your walls squeezing and pulling him deeper and you feel his warmth spill out into you. You both moan, panting as he sits still inside you. He finally pulls out, backing up from the sink and pulls up his pants and draps his uniform over his shoulders. He softly helps you get changed, hands lingering on every curve of your legs and giving you a kiss to your forehead before buttoning his shirt up.
"Do you think you can walk?"
You giggle a bit. "I should be fine."
He presses a kiss to your lips and you lean in, smiling at his touch. He pulls back, noses pressing together. "I love you."
"I love you, too."
