     also important headcanon: tougou used to sell his body for money. as
     you can see oso does it in this fic because he genuinely likes sex
     but you get the idea
See the end of the work for more notes
Osomatsu finds him on the subway. He’s sitting before Osomatsu in a burnt-
orange seat, between a woman and a businessman. The woman has her legs neatly
pressed together, a pink hand-purse resting in her lap. Underneath her shades,
Osomatsu can make out the wings of her long, fake eyelashes and a sliver of
ferociously hazel eyes. The businessman, meanwhile, slouches forward and tugs
sharply at the head of his blue tie. Sleep deprivation tugs at underneath his
eyes in the form of purple bags and overwork sleeps in his
hair. If he wasn’t so disheveled, though, he had the face to become a fine
bachelor for someone. Osomatsu glances at the man’s right hand, which is absent
of a ring. He would’ve be a great candidate, if the man sitting next to him
hadn’t already caught his attention.
The man who he has set his eyes upon has the weight of age on his clothed
shoulders and a few hard lines set into his sharply featured face. He snaps his
arm up to check the time on an expensive timepiece, which contrasts against the
drab of his worn brown suit. Using the same arm, he takes out a black pen from
his inside suit pocket, and crosses out something in the small journal that he
holds in his other hand. Yellow pages curl around his thumb as he presses down
into the spine to hold it.
Osomatsu’s been watching this man’s hands for a while. He thinks it’s something
about the way he poises them, about the way his joints are angled just right.
He’s enraptured by how he holds the pen and writes—his writing, evidently, is
not as beautiful as his hands are, but that’s alright. He imagines those hands
grabbing at his hips and thighs, leaving purple bruises for later. A shiver
rolls up his spine and a smile crosses his lips. Yeah, this man is definitely
the one.
The subway purrs as it applies its brakes and slows to a stop at the next
station. It breathes out people and breathes in more, and now there’s figures
crowding under greasy white handlebars, holding on with only their first two
fingers. As the woman gets up and leaves, Osomatsu swiftly catches her seat.
The intercom spits out an automated message before the doors slide close, and
the subway begins its fast gallop onwards. Osomatsu grins slyly as he leans up
against the man who caught his eye and rests a hand on his thigh, gently
massaging it between his palm and fingers.
“Hey old man,” he breathes against the shell of his ear, “I’m a little lost.
How about you take me home with you?”
The man shuts his journal and slips into his suit pocket alongside his pen. A
voice rolls out of him, a low growl marked by the harshness of cigarette smoke.
“I have no interest in brats like you.”
“Come on...” Osomatsu pouts, “you know, people like me have to make their money
somehow. I’ll even give you a discount, since I like you.” Osomatsu lets his
hand trail upwards and he can’t help but notice the flinch that passes under
his fingers.
“You’re not even out of high school yet.” He turns to look at Osomatsu and even
though age has softened it, there’s a sharpness to his gaze that raises the
hairs on the back of Osomatsu’s neck. Osomatsu licks his lips, rolling his
bottom lip between his teeth. “Mmn, so what? A lot of people like uniforms, so
that’s why I keep it.” Osomatsu rolls his shoulder and lets part of his gakuran
slip off, “I can take it off if you’d like though.” He shoots a wink at him.
He’s answered with a deep sigh. “Can I pay you to get lost?”
“I’m already lost, and you’re what I found.” Osomatsu grins and removes his
hand, only to place it on the other’s chest this time. He moves downwards and
brushes up against a hardening nipple, grinning at how the body under him
tenses up in kind. “What’s your name? Gotta know what I’m gonna call you
later.”
“You don’t need to know that, because you won’t be coming with me.” He plucks
the hand off his chest and shoves it back into Osomatsu’s lap, grimacing.
“Ooh, feisty. Anyway, what makes you say that for sure? Someone as tense as you
could always need a little unwinding…”
“No.”
“Please?”
“...”
Osomatsu drags his tongue against the shell of his ear. “Please?" he whines
breathily.
His hand snaps up to cover his ear with his palm. “Tougou.” he barks, a light
flush blooming on his cheeks.
“It’s a pleasure to meet you, Tougou-san.” Osomatsu flashes a bright smile,
“I’m Osomatsu. I’ll be taking care of you tonight, okay?”
Tougou grumbles miserably, hiding his face in his hands.
 
===============================================================================
 
They come across an apartment complex that Osomatsu can describe in two words:
old and run-down. The pair slowly make their way up creaking, rust-eaten stairs
and come to a stop in front of the door that’s next to last. Tougou shoves a
hand into his pocket and feels around for his keys. Once he’s got a hold of
them, he takes it out, squinting briefly at the keyring and its adornments and
picks out the house key from the lot. Fitting it between his thumb and pointer,
he slips it neatly into the lock, turning once and pushing in.
His apartment is remarkably barren, aside from a stack of suitcases in the
corner and a crumpled futon on the other side of the room. Tougou steps in,
takes off his shoes, and Osomatsu follows, whistling lowly. “Not really living
the high life, are you, Tougou-san?”
“What would you know, kid.” Tougou crosses over to the suitcases and crouches
down, unlocking the tabs to the topmost one and throwing it open. It’s just
rows and columns of various wallets—Tougou reaches into his pocket and pulls
out another, settling it in the only available square for it to go. It rests
beside one that has a winking Hello Kitty and under another that’s classically
leather-bound. Before Osomatsu can comment however, he flips it shut and locks
it, exiting into the bathroom.
“I guess everyone has their quirks, huh?” Osomatsu comments out loud to
himself, kicking back onto Tougou’s futon. It smells like cigarettes and...old
man, he guesses. It’s not really like typical old man smell though. It’s
something more clean than that, more pleasant than the others he’s bedded. It’s
like aftershave, maybe. He’ll settle on that for now because smelling Tougou’s
sheets is turning him on. Sheesh, he hasn’t even gotten around to the foreplay.
Osomatsu pats his leg and ’shh’s his developing boner, not like it helps any.
Meanwhile, he can hear the shower starting to run. How courteous of Tougou.
Osomatsu really wouldn’t mind the smell though, if his halfie is any indicator,
he’d probably even like it.
Ten minutes later and Tougou steps out of the bathroom in a loose white t-shirt
and boxers, hair slicked down and mussed by moisture. Osomatsu is surprised by
how much younger he looks and lets his eyes roam over the light definition that
shapes his figure. His dick twitches. “Why don’t you come over here, mister?”
Osomatsu purrs, shifting aside to make room.
“Don’t think I have much choice in the matter, now that you’ve invaded my bed
space.” Tougou walks over and settles down next to Osomatsu, grunting. He sits
up on his elbows and slicks back his hair with a hand, pushing his bangs out of
his face. Osomatsu licks his lips and crawls over Tougou, hooking his fingers
into the waistband of his boxers. “Can I start?” he asks, breathing hot air
onto him.
“Do what you want.” Tougou diverts his gaze to the side.
“Oh, I will.” Osomatsu firmly tugs down, exposing Tougou. Letting a hungry
smile grow on his lips, he retrieves a bottle of lube from his hoodie pocket
and dispenses a careless amount on both his palms. He begins with a handjob,
one hand grasping at the base, while the other cradles Tougou’s balls. It’s
slow starting in order to get Tougou accustomed to the sensations, Osomatsu’s
right hand gently sliding up and down the gradually hardening length while his
left remains still. It’s when Tougou’s half-hard that things really pick up.
Osomatsu rolls his balls between his fingers and varies his pressure along
Tougou’s cock, milking him from the base upwards. The sensation of hot blood
pulsing under his palm is pleasant, and the various twitching he’s eliciting
from not only the length, but from Tougou himself is even better. He peers up
and watches how Tougou’s eyebrows knit together, how his eyes force themselves
shut. A hand threads its way into Osomatsu’s hair and tugs forward. That’s when
Osomatsu decides Tougou’s about ready.
He moves his right hand over into the crook of Tougou’s inner thigh and he
poises himself at the head, pressing forward and kissing it briefly. He wonders
if he should just take him right now, but thinks better of it, instead teasing
him some more with his tongue, lavishing his attention up and down his cock,
sucking and kissing and leaving glistening wet spots behind. He hears a
frustrated sigh and chuckles against him.
And then he’s yanked up by the roots of his hair and forced to swallow down the
entire length of Tougou’s cock. Osomatsu really couldn’t be happier, getting
harder in his briefs as he sputters and chokes. He’s quick to get his gag
reflex under control and stills, letting involuntary tears spill down his
cheeks, reveling in the way that Tougou fills his throat out. Seeing that
neither he nor Tougou were patient, Osomatsu immediately gets to work after
becoming accustomed, sloppily working his cock, nearly popping himself off only
to swallow him down again. He’s not sure when it started but he’s humming in
satisfaction, using the flat of his hot tongue to coax precum out of him. It’s
bitter when it hits but he loves the way it tastes, shoving Tougou in as deep
as he can so that it pours directly into the back of his throat. Osomatsu moans
lewdly around him and can barely hear it when Tougou moans too, low, soft, and
choked like he didn’t mean for it to come out. Tougou presses his hips up into
his mouth, rocking gently.
Osomatsu’s only encouraged further by this and works faster, bobbing his head
at a consistent pace. He labors his tongue against Tougou as he moves up and
stops occasionally to suckle at the head, lapping up beads of precum. The grip
in his hair gradually tightens and Tougou’s gentle rocking eventually dissolves
into full-blown face-fucking, thrusting hard into the back of his throat.
Osomatsu just lets it happen, his moans desperate and needy, wanting Tougou to
bury his cock down this throat and cum until he can’t anymore. Saliva trickles
idly out the corner of Osomatsu’s mouth as he lets his mouth get used like a
fleshlight, vision blurring each time he fully sheathes his length. Tougou
twitches hard in his mouth and Osomatsu braces himself—but nothing happens.
Tougou growls in impatience above him and gradually weakens in pace. It looks
like this old man needs some special “help”, Osomatsu thinks.
Slicking his fingers with some more lube, he positions his pointer finger at
Tougou’s entrance and presses gently. It slips in effortlessly, which is pretty
weird, actually. He proceeds to sink his finger deeper into Tougou, and notices
pretty quickly that he could probably fit another with how easy it was to get
the first one in. So he does, and immediately notices how Tougou throbs harder
in his mouth. Hm. Bobbing his head in order to compensate for the loss of pace,
Osomatsu shallowly thrusts in and out of Tougou simultaneously and—oh. There’s
a steady stream of precum already running into his mouth. Tougou is panting
shallowly, tightening around him and actually moves a little into Osomatsu,
pushing him deeper. He twitches hard when Osomatsu curls his fingers slightly.
Osomatsu does it again and Tougou quietly sucks in a breath, cock jumping.
A grin curls at the corner of Osomatsu’s mouth and he redoubles his efforts,
swallowing around Tougou greedily, insistently grinding his fingers against
that one spot inside of him, and looks up to find that Tougou’s struggling to
tame his expression. He’s biting the inside of his lip, flushed red from
arousal and his hair has fallen back over his right eye, partially obscuring
the unfocused look in them. Osomatsu sucks particularly hard at the same time
he pointedly thrusts into him and delights in the noise he wrings out of
Tougou, then shortly finds that a fist in his hair is tugging him downwards
again. Osomatsu takes in all of him, burying his nose into short, wiry hairs
and instead concentrates on fucking him into completion. He slips in a third
finger, and it’s not long after that hot cum spills deep into his throat.
Osomatsu whines in satisfaction as he drinks it up, milking Tougou with his
tongue. Once he’s gotten it all down, he pops off wetly and sits up, wiping his
mouth with the back of his sleeve and grinning lazily.
“I see you like being filled up down here, Tougou-san.” Osomatsu inches his
fingers forward and Tougou flinches, sensitive from just cumming. “Do you fuck
yourself like this when you’re alone?”
“No,” Tougou groans, “it shouldn’t matter to you anyway. Keep out of my
personal business and get out of me already.”
“I guess finger-fucking yourself can be tiring for an old man,” Osomatsu
continues, ignoring Tougou, “so I bet you use a vibrator. A nice, thick one
that stretches your insides out.”
“How about you shut up?” Tougou snarls, growing just a shade redder.
“Looks like I hit the nail right on the head.” Osomatsu shallowly thrusts in
and out, forcing a hard flinch out of Tougou, “How do you fuck yourself? Hard
and fast, or slow and sweet?” He marks the sentence with a particularly hard
thrust that draws a startled noise out from Tougou.
“Osomatsu—” Tougou’s cut off as a shudder rolls through him, as Osomatsu sets
up a slow pace and gently rocks in and out of him.
“What was that? Couldn’t quite hear you.” Osomatsu grins, watching as Tougou’s
cock twitches and stirs, “You’re getting hard again. Do you wanna be filled
that badly?”

“Shut up and stop moving—” Tougou hides his face in his arm, clenching his
teeth. With the next thrust, his spine arches up involuntarily and a sharp
exhale hisses out of him.
“You want to get fucked, don’t you? Even though you just came?” Osomatsu moves
faster and Tougou chokes back a yelp, his knees starting to come together, but
Osomatsu uses his free hand to push one leg open by the thigh. “You’re such a
perverted old man, you know.”
“Stop already you fucking brat—!” Tougou gasps, horribly overstimulated,
twitching and curling away from Osomatsu’s fingers, but Osomatsu keeps him in
place with a steady hand on his thigh and soon enough, Tougou’s hard again.
“Look at you, all ready to go again! I wonder who’s the real slut here, me or
you?” Osomatsu snickers and makes it a point to go at only a moderate pace but
enter into Tougou as roughly as he can, taking his time to grind at length
against that particular spot in him.
Tougou cries out, a pitchiness to his voice that wasn’t there before, trying to
vocalize complaints that just end up dissolving into various, breathy sounds.
His arm moves slightly and Osomatsu briefly catches a glint of hot tears before
Tougou conceals his eyes again, tensing up suddenly.
Tougou’s breath hitches and he shudders hard, clamping down around Osomatsu’s
fingers, arching his back even further, mouth open in a wordless shout. He’s
not actually cumming though and Osomatsu’s pretty confused until he realizes
what this is, finally stilling inside of Tougou.
“So you went and had yourself a dry orgasm, Tougou-san? My fingers felt that
good inside of you?” Osomatsu withdraws himself and pushes Tougou’s legs apart
with little effort, licking his lips hungrily. Tougou doesn’t even give any
indication of meaning to reply, panting openly. Osomatsu hums, “I guess it
would be good if we took a break for the old man, then.”
While waiting for Tougou to recover, Osomatsu addresses the wet discomfort he’s
been feeling almost this entire time. Unzipping his pants, he peels his briefs
away from him and whistles lowly at the mess he’s made of himself, precum
smeared all over him and the inside of his underwear. “Guess I was a little
excited, huh?” He strips himself of his ruined garments and cleans up, swiping
the stickiness onto his fingers and sucking it off absentmindedly. Tastes
alright, he thinks. His attention trails over to Tougou and a smile plays
across his lips. He hasn’t cum himself yet, hasn’t he?
Osomatsu crawls over Tougou and positions himself so that his crotch hovers
above his face, grinning. “Hey Tougou-san, how about you do a little favor for
me?” He sways his hips slightly, “Remember that nice blowjob I gave you
earlier? Well, I still haven’t cum yet...and I was thinking that you owe me.
How about it?”
Tougou makes a small, tired noise of acknowledgement and moves his hands to
Osomatsu’s hips, gripping lightly. Giving him a once-over, he slowly guides
Osomatsu downwards until the head of his leaking cock brushes against his lips,
his tongue briefly darting out to flick up against Osomatsu. After a few more
experimental licks, Tougou gradually comes about to sucking gently at the tip
and Osomatsu shivers, restraining himself from thrusting into his mouth—he’s
seen this guy’s teeth, they’re sharp as a razor. Tougou takes a leisurely
amount of time in exploring him, sucking wetly along his length and messily
dragging his tongue across in long strokes. Osomatsu exhales shakily and whines
in impatience, twitching above Tougou.
It’s a period of time before Tougou finally takes him in, carefully easing him
into his mouth, coaxing Osomatsu’s hips to follow suit with a firm grip.
Osomatsu moans openly, stifling his desire to just throw his hips down and fuck
his mouth. Tougou, after having fully sheathed him, begins to work at an
unhurried pace, making small noises of enjoyment around him. Osomatsu himself
lets out much louder vocalizations and worries at his bottom lip with his
teeth. He tilts his hips forward experimentally, testing his limits, and is
surprised when he’s met with no resistance. Allowing himself to rock shallowly
in and out of Tougou’s mouth, he feels himself twitch at the enveloping warmth.
“Mmn, Tougou-san…” Osomatsu purrs, “I’m gonna go a little faster now, okay?”
Tougou hums as confirmation and Osomatsu groans in response, rolling his hips
down, hitting the back of Tougou’s throat. Tougou grunts in discomfort and
chokes, muscles fluttering around him briefly. Osomatsu gives him time to
adjust to the depth before resuming, a dazed grin overcoming his expression as
pleasure gently washes over him. Tougou’s hold on his hips becomes firmer as a
gradual pressure builds in his lower abdomen, inviting him into moving faster.
So he does and Tougou makes this deliciously low sound that Osomatsu can’t help
but thrust into, which draws out a long, needy moan from himself.
“You’re so good,” Osomatsu wets his lips, “you’re doing such a good job, making
me feel like this with only your mouth.” Osomatsu wonders if it’s the praise
that did it, but Tougou groans softly and presses upwards into him. Osomatsu
continues, picking up speed again, “You’re taking in all of me so easily,
Tougou-san. Do you like being used like this? Mm, then why don’t you be a good
slut and let me fuck your mouth like you deserve?”
Tougou moans quietly and lets his hands slip from his hips to his thighs, which
Osomatsu takes to be a ‘yes’. Without further delay, he happily rides Tougou’s
face, thrusting in and out of his mouth, not letting the small sounds that
occasionally slip out of Tougou go unnoticed. More pressure builds, dangerously
climbing now, Osomatsu’s voice getting breathier and pitchier along with it.
His thrusts into him grow increasingly more messy, fast and desperate now that
his completion is nearly upon him.
“You’re so good Tougou-san. I bet it’s hard to breathe, isn’t it?” Osomatsu
interrupts himself with a groan, “You can keep it up for me, won’t you? You’ll
be my little fucktoy until we’re done?” Tougou responds, letting out a trailing
moan that forces Osomatsu into near-finishing with the vibrations. He manages
to choke, “I’m gonna cum—!” and then releases, buried deep in Tougou, rocking
his hips and groaning.
When he withdraws he’s still hard. Osomatsu gives himself a moment to recover
before getting off of Tougou, repositioning himself where he was before,
situated in the space between his open legs. Tougou’s hard and leaking for the
third time and it’s not much of a surprise, but it still brings a self-
satisfied smirk to his face. His eyes trail up to Tougou’s face, smile
widening. The man looks thoroughly ruined. Tougou wipes off the mess dripping
down the side of his mouth with the collar of his shirt, licking up the residue
he couldn’t get. He then slowly shifts his gaze down towards Osomatsu and
subtly rolls his hips down into his length. Osomatsu snickers, “Impatient? Good
thing I’m already like this.”
“Get on with it.” Tougou croaks.
“If you want it so badly, how about you ride me?”
Silence. And then, “Fine.”
Osomatsu is briefly stunned by the immediacy of his compliance. “I didn’t
actually expect you to agree that fast.”
“I’m horny. Who’s fault do you think that is?” Tougou sits up and kicks off his
pants, which are still clinging onto his legs. “I came two times already, I
can’t think straight anymore,” he snatches up the lube, “and I haven’t wanted
to be fucked this badly in years. Again, who’s fault is that?”
Osomatsu rolls his shoulders, grinning up at Tougou, “I dunno, you tell me.”
“You’re such a fucking smug brat.” Tougou works himself open with the lube—not
that he really needs to—and growls lowly. A shiver dances up Osomatsu’s spine.
He watches closely as Tougou thrusts down into his own fingers and, fully
submerged, lets out a frustrated huff. He soon withdraws his hand and uses it
instead to steady himself, gripping Osomatsu’s shoulder while straddling him
with his legs on either side. “Get ready.” he warns, a growl rolling through
his voice. Using his right hand he aligns Osomatsu’s cock with his entrance and
sinks down into him all at once, which elicits a moan from the both of them.
“You know, I honestly didn’t think I’d be the one fucking you when I picked you
up. Usually old men like you like giving, not receiving.” Osomatsu purrs, “But
aren’t you a gift.”
“I had a history like yours when I was younger. It doesn’t matter much.” Tougou
slowly rises and then moves back down on Osomatsu, moaning softly.
“So you really are a little fucktoy like me, huh? Well,” Osomatsu rests one
hand on Tougou’s hip while the other winds back. He brings it forth and spanks
him hard across the ass, the smack resounding loudly in the room. “ride me a
little faster, why don’t you?”
Tougou jolts and lets out a sound of surprise, stilling in his astonishment.
Osomatsu raises an eyebrow, “Did you hear me, or do I need to do it again?” He
smiles and palms the affected area with his hand, gently massaging the flesh
between his fingers.
Tougou wordlessly picks up the pace, lifting up and then sitting down onto
Osomatsu’s cock, the sound wet. “Good boy,” Osomatsu praises and Tougou
squeezes around him, Osomatsu groaning low and bucking his hips in response.
Tougou chokes on a whine and his hips stutter, to which Osomatsu answers with
another slap. “Come on, we’re just getting started!” he teases. Tougou sucks in
a breath, gripping tighter around his shoulders.
They eventually match pace with each other, Tougou going down as he’s going up
and vice versa. Osomatsu gets to become very vocal about his pleasure—Tougou’s
so hot around him that he can barely think. Osomatsu roughly grabs both of his
ass-cheeks and spreads them apart, fucking him faster, which Tougou takes as a
cue to go faster himself. He bounces on his cock, a plethora of breathy sounds
escaping him, and Osomatsu finds it a suitable time to spank him again, causing
a groan to rise out of him. Osomatsu laughs breathlessly, asking, “You like
that, don’t you?” and does it once more, adding, “What a perfect cumslut.”
Osomatsu eventually notices that Tougou’s slowing down and chalks it up to his
age. He sits up into a kneeling position, lifting Tougou’s hips up, and hooks
one of his legs over his shoulder, continuing to fuck him at the same pace.
Praises and sighs fall forth from his lips and Tougou responds, shivering,
twitching and getting so tight around Osomatsu that it almost gets hard to
withdraw out of him. Tougou cums once, spilling across his stomach, but
Osomatsu doesn’t stop and in fact changes their position so that Tougou is
kneeling too, using his arms as leverage, holding tight to his wrists as he
pistons into him. Tougou just hangs his head and lets his body be used freely,
uncontrollably shuddering from the overstimulation and is driven straight into
another orgasm before Osomatsu empties into him with a growl. Osomatsu doesn’t
pull out. Tougou pales, weakly trying to tear away from him. It doesn’t work,
Osomatsu a vice around his wrists.
“Hey old man, wanna go again?” Osomatsu cheerfully suggests, tightening his
grip.
“No.” Tougou croaks, a cold sweat breaking out on the back of his neck.
“Well, too bad!” Osomatsu hums, moving already, ignoring Tougou’s tired groans
and half-hearted protests.
“Here we go again~!”
