****** Better Than Ice Cream ******
by Cheylock
Summary
     There are several things Stiles and Isaac aren't allowed to do
     together anymore, and one of them is go to Sonic.
     It sounds stupid, but it's a rule they've both agreed on, even though
     they both love the ice cream there and Happy Hour is probably the
     coolest thing ever.
     It's more for the employees.
Notes
     Prompt: Lick.
     Also SO PROUD OF YOU FOR FINISHING! /claps
Isaac'd been thinking when he ordered an Oreo Sonic Blast, as he was sure
Stiles'd been thinking when he ordered a Reeses one--'that is my favorite ice
cream and it is hot out today'd been pretty much it, and that didn't sound too
unreasonable or anything.
The only issue is the fact that Stiles did not eat anything like a normal human
being, least of all ice cream. 
Then, Isaac isn’t even human, and from the look on Stiles's face, he’s eating
his weird, too.
They spend almost ten minutes sitting in the parking lot, pretending to listen
to the Top 40’s music playing through the tinny speakers set above the jeep,
eating and watching each other. Stiles is the first to break, because he always
is. "Why're you looking at me like that?"
Isaac makes the situation worse, mostly because he finds it hilarious but also
because he's quickly hardening in his jeans and he'd like to not be the only
one with that problem. "Stiles, do you really not realize what you're doing?"
Stiles shakes his head and grins, and Isaac knows it means exactly as much
trouble as he’s plotting, himself. "Show me."
Isaac smiles, the wicked grin that still feels just the littlest bit foreign on
his face after the moon wanes, and then he gets a full spoonful of combination
ice cream and whipped cream and licks straight down the middle in a curvy
trail, barely easing the tip of his tongue into the chill.
Stiles squirms in his seat and wets his lips.
Isaac raises an eyebrow, then laps, full and heavy licks that coat his tongue
with ice cream quickly but are still delicate, and then he goes in for the
kill--he pops the whole head of the spoon into his mouth and sucks. Very, very
obviously. And he swallows while he’s doing it, a skill that took him a little
while to master.
When Isaac finishes the spoonful, Stiles is sitting there with huge starving
eyes, one hand settled over his obviously hard dick, rubbing it just barely
through his jeans, and Isaac looks at him earnestly. "See, this is why we
shouldn't go out for ice cream ever. Your oral fixation makes even the most
innocent things dirty as fuck."
"I'll give you oral fixation, asshole--backseat?"
"Backseat."
Isaac sucks Stiles off first, not through any defined order as it stands but
because Stiles scrambled back first and was already sitting down. The position
is awkward--Isaac has to cram his inordinately long legs in very strange
configurations to finally suck Stiles's cock into his mouth, but when he does
he's rewarded with a high whimpering whine and Stiles's long fingers fisted in
his hair. "Yes--oh--yes, Isaac, fuck--"
And then Isaac does what he does best and concentrates on making Stiles lose
his words. It's not that he doesn't like Stiles's words; Stiles just seems so
much fucking happier without them.
It doesn’t take as long as it maybe ought to because Stiles is horny and Isaac
is horny and also Isaac is officially spectacular at blow jobs now. The first
couple were sloppy and terrible (Stiles came anyway, but they were still bad,
he knows that now that he knows how to give a good one)--mostly because he had
no idea that he wasn’t supposed to just gob on the saliva and hold his head in
one spot and suck--but he decided to get good at it. Stiles’d been up for
literally anything and willing to practice whenever Isaac was, so they’d both
gotten pretty goddamn excellent at getting each other off within less than two
weeks.
They’re nearing the year mark now, and it’s no small pride to Isaac that he has
Stiles’s hips bucking in less than ten minutes. Sometimes they draw it out and
make it last, when Isaac sneaks over when the Sheriff’s out, when they have no
homework after school and the Sheriff’s still out--but mostly they’re dicks
about it. They actually had a game going at one point, but looking at a watch
while you’re trying to make someone come kind of kills the entire thing for the
person doing the sucking, as far as Isaac’s concerned
Stiles is still ridiculously proud of the fact that he was winning after having
made Isaac come within a minute one day after lacrosse.
Isaac says it’s still under debate, that the fact that Stiles was naked (rare
as hell) and also touching himself (which probably would’ve made Isaac come all
on its own) makes it more than just a blow job. But he’s mostly weirdly proud
of Stiles for thinking of it before he did.
Isaac's eyes roll back when Stiles comes into his mouth on one of the upward
bobs of his head because they always do and they probably always will; mostly
he loves that he can accomplish that but also it just fucking makes him hot,
and Stiles makes all kinds of begging and gasping noises that Isaac never wants
to stop hearing but will of course fade out a few minutes after Stiles’s cock
is safely back in his pants.
 
The knock on the window comes about thirty seconds after Stiles puts his mouth
over Isaac's cock, and the manager threatens to get them fined and Isaac
threatens to kill her and Stiles, having just had a very nice orgasm provided
by Isaac, tells them both to quit it and that he and Isaac are leaving.
So maybe they don't go to Sonic anymore because they're banned, and yeah, that
was the most embarrassing thing that's happened to Isaac since he got turned,
but he got his blow job a couple minutes later in the parking lot of Beacon
Hills Wildlife Preserve and there's a Dairy Queen opening next week anyway, so
he's a pretty happy guy.
