****** Mine's Bigger ******
by Celianna
Summary
     "Mine's bigger," says Momo. "No, it's not," protests Kaidoh.
Notes
     Rating for smut and swearing. In which I try to never say the actual
     word. You know which word. More MomoKai can be found under my name.
“Mamushi, hand me the soap.”
Kaidoh ignores Momoshiro.
The stall next to him starts to vibrate from the banging. “Yo, don’t ignore
me!”
Kaidoh runs his fingers through his wet hair, and hopes the water will drown
out the idiot's voice. But it doesn’t, of course, especially since Momoshiro is
now lifting himself up and hanging over the edge of his stall, so that he can
completely see into his own stall. Kaidoh looks up with the meanest glare he
can muster. Momoshiro looks at him with a smirk.
“Give me your soap,” he says.
Kaidoh kicks the stall so that it sends Momoshiro flying off of it, and he
lands on the tiles with a loud thud. And a curse. To top it off, Kaidoh flings
the soap bar towards his stall, and miraculously, it lands on top of
Momoshiro’s head – judging by his screaming that is.
“Bastard Mamushi,” he yells.
“Dumbass,” says Kaidoh in return.
He’s back to running his fingers through his hair, letting the shampoo run out
of it. Momoshiro seems to be busy using the soap, as he’s finally shut up his
mouth, which is good, Kaidoh thinks. The water feels nice and hot, and it’s
running down his back, his shampoo now completely out of his hair.
Then Momoshiro’s back up on the stall, leaning over, his chin resting on the
edge. He has the bar of soap in his hands, and Kaidoh assumes he was going to
give it back. So Kaidoh stares at Momoshiro, who stares back at him. They’re
silent. Then Momoshiro’s eyes trail downwards, traveling across Kaidoh’s
completely wet and naked body. And he stops, then his eyes meet up with
Kaidoh’s again.
He grins with a triumphant scoff. “Mine’s bigger,” says Momoshiro.
“No, it’s not,” protests Kaidoh. It is an instant reaction, because whatever
Momoshiro says, it’s not, because Kaidoh is better than him. Always. No matter
what.
“Yeah it is, just look how puny yours is,” says Momoshiro with a laugh. The bar
of soap slides out of his hand as he laughs, landing on the floor. Kaidoh
ignores it.
“Disgusting pervert,” says Kaidoh, then proceeds to ignore Momoshiro and goes
back to washing himself.
Momoshiro slides off of the stall, and is silent for a while. Well, for three
exact seconds that is.
“You’re just mad ‘cause I’m bigger than you.”
Then Kaidoh lifts himself up to look into Momoshiro’s stall. Noticing the
viper’s stares on his back, Momoshiro looks up with a wide smile, then thrusts
his hips forward. Kaidoh pulls his face into a grimace, nasty, he didn’t need
to see that.
“Moron, obviously mine’s bigger. You’re barely two inches. Learn to measure,
dumbass.” And Kaidoh is back in his own stall, ignoring Momoshiro’s obvious
taunting.
Momoshiro finally stops calling him names and it’s silent for a bit. He hears
some strange sounds coming from Momoshiro’s stall, which makes him wonder. It
sounds squishy.
“There, now mine’s obviously bigger. I win,” says Momoshiro.
“Dumbass, how could it be any bigger than –” Kaidoh catches himself just in
time. “Oh, that’s gross, you’re fucked up.”
“You’re just a big loser,” he taunts him.
“Am not, you’re the loser.”
“Yeah well, prove me wrong then, huh.”
Kaidoh once more peers into Momoshiro’s stall, and he looks down. It’s half-
hard, and grown by about two inches. His eyebrows pull into a frown. Nasty. But
all he can think about is; he can't let him win, now can he?
“That’s nothing,” says Kaidoh as he slips back into his own stall.
Momoshiro, the curious dumbass of course, immediately leans onto the edge as
well, and watches Kaidoh. He tries to ignore his stares, because it’s awkward
and embarrassing, but then he remembers that this is just another competition
between them, and his hand glides in between his legs. He fumbles around a bit
with his own equipment, his hand making quick work of it, and slowly it starts
to enlarge.
“Oooh,” says Momoshiro as his eyes watch Kaidoh doing quick pulls with his
hand. “Trying to out-do me, huh?”
Kaidoh then stops, it’s half-hard, and his cheeks are a bit pink, but he
doesn’t care, because it’s bigger than Momoshiro’s. He cracks a rueful smirk at
Momoshiro, who’s still leaning on the edge of the stall and looking down at
him.
“That won’t do Mamushi,” he says as he inspects Kaidoh’s lower region. “I’m
still bigger.”
Kaidoh hisses out loud, not believing a word he says. “Yeah right. Dumbass.”
But he can’t help but take a look anyway, just to make sure.
Momoshiro slides off of the stall so that Kaidoh can see it, and it’s grown by
another two inches, protruding from his hips, perfectly horizontal. Kaidoh’s
cheeks flash with heat; when did he ... ? It can’t be because he was watching
him do it ... right?
Kaidoh can’t let him win, so he gets down to business again. It’s awkward with
Momoshiro hanging over his stall again, watching him as he glides his hand over
it, but he closes his eyes and does it anyway. It gets bigger, and bigger, and
his breath is quickening up as well. Kaidoh rubs for a few more seconds than
necessary, he’s starting to like it now, obviously, since it’s hard and all.
Then he stops, and smirks at Momoshiro, who’s been watching him all this time.
“I win,” he says.
Momoshiro’s face disappears from the top of his stall, and then he hears a door
opening, and suddenly Momoshiro is inside of Kaidoh’s stall.
“No way, I’m obviously much bigger, see?” says Momoshiro as he struts inside,
their arms touching and sliding under the hot water.
Kaidoh’s eyes widen, and he wants to shove Momoshiro out of the stall, this was
too weird. He huddles himself in the corner as Momoshiro blocks the door.
And then he looks down, and so does Momoshiro.
It looks about equal.
“I’m bigger.”
“Fshuuu, no you’re not.”
Momoshiro steps forward and grabs Kaidoh’s arm, and pulls him closer. Kaidoh
slips on the bar of soap, but catches himself in time so that they don’t crash
into each other, and then he feels it bump into Momoshiro’s and it slides
forward. Kaidoh closes his mouth; his cheeks are burning red.
Momoshiro is still holding onto Kaidoh’s arm, and he looks down, as they’re
touching each other. “See, I win.”
Kaidoh also looks down, and it’s strange to see another man’s thing pressed up
against his. It feels warm and soft. For a second, he forgets it’s Momoshiro’s.
“Dumbass, you need glasses, I’m an inch longer,” he says with a shaky voice. He
doesn’t dare to look up at Momoshiro now.
Momoshiro leans closer, and Kaidoh hisses as it slides down the entire length,
and pokes him in his thigh.
“You’re the one who needs glasses,” mumbles Momoshiro. His hand is still on
Kaidoh’s arm.
Kaidoh growls, then pushes against Momoshiro as well, and he feels it poking
his thigh now too. That’s what the idiot gets for starting it. Not because he
wanted to or anything. The water continues to hail down above the two boys, and
they’re quiet for a few seconds. That is, until Momoshiro shifts his weight,
causing it to brush against his, and it twitches in response.
“Oh?” says Momoshiro, surprised. Kaidoh turns his face away, embarrassed.
“Getting turned on now, are we?”
“Who’s getting turned on, dumbass. It obviously isn’t me. You got in here
first,” spits out Kaidoh. “You’re the pervert.”
Suddenly, very unexpectantly – Kaidoh didn't quite think of this ever happening
– Momoshiro pulls himself closer, the grip on Kaidoh’s arm now clawing his
back, and they’re rubbing each other again that it makes Kaidoh’s breath stop
for a few seconds. Their chests are touching, and well, basically almost
everything is touching now, and Momoshiro leans his head on top of Kaidoh’s
shoulder, his mouth close to his ear.
“I bet you’d be the first to come,” Momoshiro whispers into his ear, his tone
mockful and arrogant.
Kaidoh's face grows an even deeper shade of red, and he lets out an annoyed
hiss. A challenge, he'll accept it. Kaidoh lets out another (embarrassed) hiss,
and then puts his arm on Momoshiro’s back as well, and buckles his hips against
him. Their shafts slide up against each other, and he feels Momoshiro’s legs
jerk in response, and he lets out a harsh breath in Kaidoh’s ear.
“I’m not gonna lose,” whispers Kaidoh back in a dangerous tone. He's not. He
can't lose to Momoshiro.
That was all that needed to be said to get the two boys to start humping each
other. Momoshiro was the first to start, he grinds his hips into Kaidoh’s, and
their lengths slide up against each other, both standing up straight, huddled
between their bellies. Both of them take in a sharp breath. Kaidoh presses his
fingers onto Momoshiro’s shoulder blade, and uses it to support himself as he
thrusts into Momoshiro once more. They rub against each other, and the heads
are sliding up and down, and it feels really good, despite how embarrssing it
really was.
Momoshiro groans into his ear; it sounds really hot and enticing, which only
serves to make Kaidoh harder. Then Momoshiro’s hands are on his ass, and Kaidoh
wants to protest, but Momoshiro uses his new leverage and pulls him into his
hips, the length now not only sliding up against his, but over the soft flesh
of his stomach as well. Kaidoh’s knees buckle and both him and Momoshiro crash
against the stall. It feels good, but damnit, he can’t let Momoshiro win.
Kaidoh finally grabs Momoshiro’s wrist away from his ass, and he slams them
against the stall, pinning him up. They look each other in the eye, and
Momoshiro gives him a half smirk. Kaidoh hisses, he’s not really sure of what
to do, but everything’s pulsating down there, feeling soft and squishy and
good, and there’s Momoshiro, who’s just smirking at him with those idiotic
lips. He’ll show him, he can make him buckle his knees as well.
So Kaidoh bends down his head and plants his lips on the side of Momoshiro’s
neck. At the same time, he pushes himself into Momoshiro, and he feels their
hard lengths sliding up again. Fuck, that felt good for him too, so he sucks
harder on Momoshiro’s neck, who is now gasping for air, and trying to wriggle
free from Kaidoh’s hold. It feels rather good to be the one in control, and
he’s smirking against Momoshiro’s neck because he can’t do anything in return.
Well, it seems Momoshiro could still do something, because he has lips as well,
and they’re suckling on Kaidoh’s ear. Kaidoh pulls away from Momoshiro’s neck,
and he can’t help but let the half hiss and half moan escape from his mouth,
and he rocks into Momoshiro some more.
Momoshiro’s hips are moving with him, and they’re sliding and rubbing and
humping each other. Kaidoh’s grip on Momoshiro loosens, and he finally breaks
free, his hands on his ass again and pulling him closer. He doesn’t protest
this time, in fact, he’s sort of lost sense of what was going on when
everything felt so good.
“Heh, that’s it, Mamushi,” says Momoshiro in a relaxed voice. Then his lips are
on his earlobe again, gently biting on it.
“Fuck,” yells out Kaidoh and angrily grinds into Momoshiro. “Don’t call me
Mamushi.”
One of Momoshiro’s hands disappears in between their bodies, and Kaidoh vaguely
wonders what he’s trying to do, until he feels his fingers wrap around his
shaft. It fills him up with adrenaline, and to let out this build-up of
hormones, he sucks on Momoshiro’s neck again, hard. Because that’s the only
thing that keeps him from moaning out loud and coming right then. Then he feels
Momoshiro press his length against him as well, and he’s holding both of them
in his hand, and through Kaidoh’s rocking, it slides in and out and it feels
fucking fantastic. Kaidoh doesn’t care anymore, and he quickens his pace,
slamming into Momoshiro, and he feels it going in and out of Momoshiro’s hand,
along with his soft and throbbing shaft.
“Mamushi, Mamushi,” chants Momoshiro.
That would have bothered him, if only it didn’t sound like he was cheering
Kaidoh on, and it was in fact, helping him get near the end. He sinks his teeth
on Momoshiro’s neck, and Momoshiro yelps out loud, and he smiles because at
least he stopped calling him Mamushi.
And then Momoshiro starts to slide his hand up and down as well, and it feels
like he’s going in and out of a really long tunnel, and Kaidoh squeezes his
eyes shut as he takes a deep breath. It feels so close, everything’s pulling
closer and coming together. He bites down harder on Momoshiro’s neck, and
drawls out a few low moans, which sends Kaidoh over the edge. He lets go of the
delicate flesh, drives hard into Momoshiro, and then he feels his muscles
contract, and his facial features pull together in a grimace, and then he lets
it all go in one explosion.
“Fshuuuu,” he hisses as he feels his muscles spasm and contract at the same
time, pumping out his seed. He’s riding the waves of his orgasm, and he’s
shaking and still rocking into Momoshiro.
“Ah,” says Momoshiro before he’s buckling against Kaidoh as well. Kaidoh
assumes he’s coming as well, but he can’t really tell when they’re constantly
being drenched by warm water, which is already cleaning off his sperm from his
stomach and legs.
Momoshiro breathes deeply into Kaidoh’s ear, and Kaidoh is still leaning his
face in Momoshiro’s neck. Since he's still out of it and riding the wave of his
orgasm, it sort of feels nice like this. It only lasts for another two seconds
before Momoshiro starts to push Kaidoh away from him. He staggers backwards.
“Get off, you’ve been pushing me against the stall the entire time. Jackass,”
he says angrily.
Kaidoh stands in the middle and lets the water wash away all of the stench, and
the stickiness. He looks at Momoshiro, whose face is red and eyes are half
closed. He looks down, and sees that it’s already going limp. But so is his
though.
“Serves you right for calling me Mamushi.” It's the only thing he knows what to
say after doing something like ... that.
That makes Momoshiro’s head turn even redder, he’s probably recalling how he
was saying his name out loud as they humped against each other. Not that this
doesn't make Kaidoh blush either.
“Whatever.” Momoshiro rubs his nose, then pushes the door of the stall open. “I
still win by the way.”
Kaidoh hisses loudly. “Next time!” he calls out, but Momoshiro has already left
the stall.
