Summary
     <me> hey. what do i want to call this?
     <Zee> Call it 'The Best Crossover EVAR'
     <me> NO IT NEEDS A REAL TITLE
     <Zee> Um.... 'The One Where Seth Blows Bart'?
     <Zee> What about just, 'The Day I Met Kid Flash'?
     <Zee> Dude, i suck at titles.
     <me> ahahaha.
     <me> me, too. man.
     <Livia> "This is how we do it in the Speed Force, bitch!"
Seth's tying his shoe.
This is, generally, a pretty safe activity. He notices it's untied, steps off
the sidewalk onto the grass, and crouches down to solve the problem.
This time, a pair of weird-looking red and yellow boots stops next to him.
"Hi," a voice says, from the general direction of above the boots. "I know this
sounds kind of strange, but can you tell me where I am?"
Seth stands up. He turns his head a little, to look at the owner of the weird
boots, and the voice. "Um," he says, and then "Holy fuck." And then, "You're
Kid Flash."
"Yeah." His eyes are really yellow, and they kind of shine. It almost hurts
Seth to look into them. "This isn't San Francisco, is it?" He sounds kind of
hopeful, but not overly-so.
"Uh, no. You're about," Seth pauses to think. "Four hundred and fifty miles
off. Or so." You're Kid Flash, he barely resists saying again.
"Oh." He crinkles his nose up a little, thinking. "That's weird. I wonder how
that happened. You haven't seen Superboy around, have you?"
"No. Um. Not to sound stupid, but ... You're a comic book character," Seth
blurts out, finally. It sounded way more suave and intelligent in his head.
"Because he was transported with me, see, and ..." He trails off. "I'm a comic
book character? Really? That's so cool! Do you have any? Can I see? Wait, does
this mean you know my secret identity? Wow. This really is another dimension!
Robin'll be totally excited!" He pauses. "If he can figure out how to get us
back. You don't have a dimensional transporter, do you?" He has that hopeful-
but-not-counting-on-it look in his eyes again.
"Um." Seth stares at his feet. "Yes. No. Sorry. I mean." He looks up again.
"Yes, I have comics with you. No, I don't have a dimensional transporter. Those
don't even exist here."
"Oh." Kid Flash -- Kid Flash! -- looks disappointed. And then suddenly he's a
blur, and before Seth can finish blinking he's standing there in oversized
jeans and a green hoodie with Mario on it, and there's a ring with a Flash
symbol on his right hand that Seth hadn't noticed before. "I'm Bart," he says,
and Seth says "Um" a couple more times before he manages to get his name out.
***
"I had my own series?" Kid Flash -- Bart -- is sitting cross-legged at the foot
of Seth's bed. Seth's sitting at the head of it, and between them are several
long white boxes. There are a couple more on the floor, poking out from under
the bed.
"Uh-huh," Seth says. He's rifling through a box that contains a slightly
embarrassing number of Legion back-issues. "I don't own it, but I read a couple
issues on the Internet. It was really" don't say cute, don't say cute. "cool."
"Huh." Bart leans back, dangerously far, looking like he's about to topple over
backward any second now. "But I got canceled? That's totally lame." He sits up
again, leaning forward this time, elbows on the edge of one of the boxes and
chin cupped in his palms.
"It got canceled at the same time as Superboy, so maybe there was something
going on, but I wasn't reading those then. I got Young Justice in back issues,"
he says by way of explaination.
And Bart's simply gone for a second, and Seth blinks, but then there's a weight
on the end of his bed and Bart says, "Still no sign of him. Superboy," when
Seth looks slightly confused.
"Did you just ... check the whole city?"
Bart nods.
"Awesome." He comes dangerously close to actually hitting his forehead with the
heel of his hand. Awesome? You're a moron, Cohen.
But Bart doesn't seem to mind, and just takes the lid off the box on his right.
"Wait!" Somehow, even though it should be impossible, Seth manages to throw
himself forward and cover the box with his arms before Bart has a chance to
look through it. "You can't read my comics!"
"Why not?" Bart's actually pouting, an expression that Seth doesn't think he's
ever seen on a boy's face before. Well, maybe Ryan once or twice, when he
thought nobody was looking.
"Because I don't know where in continuity you are! Past issue four of Teen
Titans, obviously, but after that there's no way to say. And you can't read
about things that haven't happened to you yet. It would be dangerous. It would
be bad. It could destroy your entire universe." Seth's a little wide-eyed, and
his breathing's a little erratic, and Bart is staring at him like he's crazy.
"It could destroy your world," Seth says again.
Bart just stares at him, and it's actually a little unnerving (those eyes), so
Seth eases up off the box and sits back up. "Um," he says. "I, uh. You know
what? I'm -- I'm hungry. Are you hungry? You must be hungry; speedsters are
always hungry. Let's get some pizza. How does pizza sound? I -- I gotta go get
a phone," and he's off the bed, edging toward the door (He doesn't have a phone
in his room; why should he? His only friend lives in the backyard.) when
suddenly he's slammed up against the door, and his mouth drops open, and Bart -
- Kid Flash -- is kissing him.
Um, he tries to say, but Bart's tongue is licking at his teeth, and it's hard
and fast and not like kissing anyone else -- not that he's kissed all that many
people. And he's not gay. He's not, really, whatever his parents or his
therapist or his girlfriend might say, but ... this is Kid Flash. He kisses
back.
And he won't say that he's never fantasized about comic book characters -- he's
a red-blooded American male, after all -- well, okay, a red-blooded American
geek -- but he never pictured it quite like this.
He drops to his knees.
Bart makes a breathy little noise that makes Seth hope frantically that his
parents haven't stopped home, even though there's really no way they could have
heard it even if they were standing right outside his door, which please don't
let them be standing right outside his door because that would be disastrous
because there's really no way to explain this and -- okay. Breathing. Breathing
is important.
Breathing is important, and ... he's actually unbuttoning Bart's fly. He's
pulling down the zipper of an honest to God superhero, and he's really glad
that Bart changed out of the Kid Flash uniform because this is surreal enough
as it is, and does this make him a groupie?
"Seth," Bart says -- whimpers really, and Seth has a moment of Woah before he
takes another deep breath and tugs Bart's jeans down, hooking his thumbs into
his -- are those Superman boxers? Oh dear God -- underwear and pulling those
down, too. The clothes puddle at Bart's feet, and ... and.
And there's a half-naked superhero in front of him in his bedroom, and Seth
thinks Oh help me, Moses and takes the head of Bart's cock in his mouth.
Bart makes a sharp "Oh!" noise and his hips press forward, just a little; Seth
almost gags, which has to be some sort of psychosomatic thing as Bart's cock is
nowhere near all the way in the back of his throat, and oh god, can he do that?
Is it actually possible to do that? He's not actually certain that it's
possible outside of those couple of pornos that okay, maybe he's seen but he's
a teenager dammit and -- Bart lets out another strangled moan, and Seth decides
he thinks too much.
Although he kind of wishes he'd ever, you know, gotten a blow job. Then maybe
he'd have some idea what he was doing.
One of Bart's hand tightens on his shoulder. The other cups the back of his
head lightly, fingers threading through his hair. They catch and tug, gently;
Seth gasps a little around Bart's cock; Bart moans, so he does it again. He
swipes his tongue gently against the underside of Bart's cock, and the fingers
in his hair tighten.
Okay. He's a quick learner. He can get the hang of this.
Just as he's beginning to think he's got it down -- and this isn't so bad,
really; he can't understand why Summer was quite so adverse to the idea -- Bart
sort of murmurs "Oh Seth" and the fingers in his hair tighten and suddenly Bart
is coming in his mouth. Which is ... simultaneously gross and kind of cool.
And okay, blow jobs are pretty easy, but swallowing is hard. He manages,
though, and is only coughing a little when Bart's hands slide down to his
biceps and he's pulled up roughly and pushed back against the door again. Bart
seems to like this kissing-roughly thing, and Seth ... really isn't
complaining.
"So, is this the place where I'm supposed to get really awkward and
uncomfortable?" Seth asks when Bart finally lets him up for air; his grin is a
little nervous, but then, it usually is.
"Not unless you want to." Bart rests his forehead against Seth's, and it's a
little unnerving to see someone grinning manically from that close up. "So how
about that pizza? Pizza sounds really good. Let's get some pizza." He finally
lets go of Seth and backs off him, and Seth reaches to the side to bedroom
door, before noticing something rather crucial:
"You, um, might want to put your pants back on." And just like that, they are.
Bart grins. Seth, not for the first time, wishes he had superspeed.
"And you know," Seth says, as they're headed downstairs for a phone, "if you
can't find a dimensional transporter ... you could probably stay here. My
parents have this thing about taking in strays."
