Summary
     The first time was an accident. The second time was not much
     different. But the third time? They invited her to watch.
Notes
     For Brii <3
The first time was an accident.

--
Allison hurried over to the now dark lacrosse field, cursing her own
carelessness under her breath. Somewhere between the game ending and heading
out to gossip and chat with Lydia in the parking lot, she’d dropped her keys
somewhere. She had realized this only when Lydia had said that she was leaving
and Allison had patted her jacket pocket for her own car keys.

A quick search of the almost empty parking lot had not revealed anything and
garnered her several concerned questions and a few helping hands. But
eventually, there was no one left but Allison and her cellphone doing slow
sweeps over the concrete.

Once she had cleared that area, Allison had gone back to the field. Maybe she
had dropped them on the way to the car. Or maybe where she had been sitting.
The eerie silence made her hasten her steps, doing quick sweeps in front of
her.

As it turned out, her keys were under the bench right next to the field,
meaning that she had dropped them when she’d gone down to talk to Stiles after
the game had ended. But all’s well that ends well right?

Wrong. 

She was ready to run back to her car when she heard something from the other
side of the field. A low thud that made her jump and whip around, heart in her
throat and body ready for an attack. Her eyes darted over the dark field,
bitterly cursing the clouds that were keeping the faint moonlight at bay. 

As though someone has heard her thoughts, the clouds floated on and let the
half moon shine down. It’s light was pale and just barely enough for her to
catch sight of the pair across from her. She felt her body grow cold, freezing
in place as she not only recognized who it is but also what they were doing.

The white 24 was easy enough to make out, same as the pale hand sliding against
dark cotton and under darker leather to rest against Derek’s chest. Stiles’
head was bobbing slowly in Derek’s lap, the werewolf sitting with his legs
spread wide to accommodate Stiles’ shoulders.

Allison stood there and stared, not daring to breathe as Derek brought a hand
down on Stiles’ head and pushed him down, down, down. She twitched and felt her
stomach flip with desire when Stiles’ hands slipped down to push Derek’s legs
open to an obscene extent and then go between his own thighs.

Derek’s head tipped back. She wondered if she had just imagined the sound of
his groan or if he had actually groaned so loudly that the sound of it had
carried all the way to her. Either way, the sound made her legs unfreeze. 

Another batch of thin clouds pass over the moon as she stumbled off the field
without a second look and blushing cheeks.  

--
The second time was not much different.

--
Considering the sheer rarity that her father was letting her join their patrol,
Allison was determined not to screw it up. It was a simple patrol of the
borders to make sure that nothing evil was afoot. A part of Allison, a big part
of her actually, hoped that there would be some kind of action because she was
itching to test her new crossbow out.

But the forest was silent for the most part, if you ignored the usual night
noises. Crickets chirped from afar, growing silent as she walked past. A bat
screeched overhead, catching the attention of the curious fox that had crossed
her path. The bright eyes stared at her and the tongue she stuck out before it
trotted away into the under growth.

She headed up to the bluff which had been her and Scott’s meeting place. For
nostalgia’s sake because she had been missing the boy fiercely this week. The
Wednesday past would have been… Allison shook her head, wanting to dislodge the
fact before it was completed.

There was no use thinking about spilled milk, especially when they both had
agreed that splitting up was the better option. But she was missing him. A lot.
So what was one moment of weakness that would be her own secret and no
one else’s? 

With a sigh, she pushed her way through a particularly thick bush and found
herself standing at the edge of the open area. And behind Stiles’ familiar
Jeep. Blinking at the vehicle, she wondered what the hell Stiles was doing out
here.

Two steps closer, Allison got a clear sight of the fogged up windows and
blushed. Well. She ought to have seen that one coming. Her brain told her to
turn around and pretend that she hadn’t come across the sight that they had.

But curiosity made her soften her footsteps as she approached the Jeep,
wondering if Stiles was with Derek again. After that night on the field,
Allison had questioned what she had seen out there. She had argued with herself
that there was just no way that Stiles and Derek could be having sex. The other
werewolves would have noticed. Scott would have noticed and said something.

But…

It was that stupid 'but’, and itching to find out if she had been right or
wrong, to find out if they really were together, that made her carefully step
up to the Jeep. A hot flush rose up her cheeks when the vehicle began to rock.
Oh God. That was just…

A hand pressed into the window, smearing the condensation there. Allison felt a
burst of giggles working their way up her throat. She quickly slapped a hand
over her mouth and tried her best not to make a Titanic joke. Her brain gave
her at least three for future reference. Just in case.

The jokes died when she saw a second hand press on top of the palm pressing
into the window. The tanned hand pushed pale fingers harder into the window
before they curled in. Allison wondered if Derek’s knuckles hurt given how
they’re pressing into the window.

It was only when the hands were pulled back that Allison realized that she was
standing right next to the Jeep. And that she could see into the vehicle
through the small clear spot. Her heart, that was already working overtime,
threatened to burst out of her chest at the sight before her.

Derek had pulled Stiles into his lap, both of them half naked in different
ways. Derek was without his shirt and Stiles without his jeans and top shirt.
Stiles’ arms were wrapped around Derek’s shoulders, eyes closed in concentrated
pleasure as he worked his hips back down on-

A spike of desire went through her, cold and hard down her spine before it
curled viscously around her stomach, at the sight of Stiles rubbing his ass
against Derek’s hard cock. The way Stiles was working his hips back, and Derek
up, you’d think that the world was ending or something. And it also explained
the way the Jeep was rocking…

Stiles opened his eyes. She noticed that they were wet at the corners at the
same instant that Derek did. Her hand twitched by her side, wondering what the
werewolf’s hand felt like on Stiles’ cheek as he wiped the tear away. Was it as
gentle as it appeared to be from the outside?

Seeing Derek look so tenderly at Stiles made her lust turn into guilt. This was
a private moment between them and no one else. She was on her way towards an
excellent lecture on why she shouldn’t be a peeping Tom or be this interested
in her friend’s sex life when she took a step back. Right on top of a branch
that cracked loudly.

Allison flinched, eyes squeezing shut automatically in response to the loud
noise. Her brain was screaming and cursing at her. There was no way that Derek
would have missed that. 

When she cautiously opened her eyes, Allison found herself staring into two
pairs of startled eyes. Without a word, she whipped around and ran away.

--
But the third time?
--
She stood in the door way, waffling between entering and running downstairs to
her car and pretending that she’d never received Stiles’ message. Stiles turned
back to give her a questioning look.
 
You don’t have to do this if you don’t want to.” He said simply, standing
between her and Derek, who was sitting on Stiles’ bed.

Allison hesitated, swaying slightly in place before she asked, “Just… Is this
okay? That's I'm here to…”

“Watch?” Derek finished, nodding in reply to Allison’s jerky nod. “It’s okay.”

Stiles grinned and pulled his computer chair forward, putting it right in line
of sight of the bed. “Pull up a chair and enjoy the show. That's why we invited
you.” She couldn’t help but smile weakly at the comment. Derek however, rolled
his eyes impatiently at the teenager.

Her body felt like it was pushing it’s way through quick sand when she closed
the door behind her and stepped over to the empty seat. Stiles was already in
Derek’s lap, long legs straddling the older man’s body as he pressed in for a
dirty kiss. Allison felt her legs grow weak and more than gratefully plopped
down into the seat to watch.

Of all the reactions that she had expected and anticipated after being caught
watching Stiles and Derek having sex in the Jeep, she hadn’t been ready for
Stiles to message her with a 'if you want to watch, you’re more than welcome to
do that from up close. my room @ 6 tonight. just watching thou.’

She wondered who she had to thank for this favor/curse. Was it Stiles who had
convinced Derek into inviting her? Or maybe Derek had liked the thought of
putting on a show for an audience? Or maybe, she wondered as she caught sight
of the hickeys littering Stiles’ body and the possessive manner in which Stiles
ran his hands over Derek’s body, they both just wanted to show off that they
were together.

It was hard going but Allison managed to sit still and watch the pair fall back
into bed, the wet sounds of their kisses making the wetness between her legs
grow and grow. By the time they were naked and Derek’s hands were sliding lower
and lower towards Stiles’ ass, Allison was wriggling in her seat. 

Derek had to have smelled her arousal, probably from the moment they had
started this strange little scene. She wondered if she could just… slip a hand
down between her skirt and touch herself, try to match the pumping motions of
Derek’s fingers as they fucked Stiles’ open.

“Fuuuck!” Stiles whined, body shaking and trembling against Derek’s while the
werewolf shushed him gently. Heat and fire had replaced the blood in her veins,
making her feel like she was burning from the inside out when Derek slipped a
third finger into Stiles’. 

She was sorely tempted to roll the chair over to the end of the bed, giving her
a better view of Stiles being fucked. But this was better. From this side, she
could see their faces and how affected Stiles was. Allison stared at the
fluttering lashes, the furrowed brow, the red mouth and most importantly, the
lust-love struck eyes that were locked onto Derek. 

The looks that they share, long and lingering, are far more arousing than the
sight of Stiles sinking down on Derek, bareback. She got to see exactly
how much the action was affecting them both. The pinched frowns, surprised
inhales and trembling smiles that flitted over their faces were like a punch to
the stomach.

When Stiles reached out to take hold of Derek’s face in his hands, her own
fingers clenched around her skirt. A strange mix of curiosity and envy flooded
her the longer the couple held each other’s gaze, acting for all the world that
they were alone and she wasn’t there.

This was more than just sex, that much was clear. And it seemed that maybe they
knew this? They had to right? There was no way that either of them could not be
aware of that. It was apparent in the way Stiles’ legs tightened around Derek
when he was rolled over on his back. In the way Stiles kept his grip on Derek’s
face, holding his gaze even when his body began to tremble with pleasure. In
the way Derek listened to all of Stiles’ breathless pleas and demands and gave
the teenager everything he asked for and then some.

This wasn’t sex. This was making love, as corny as it sounded. But that’s what
it was. The realization made her flush harder than she had before and avert her
gaze down at the floor. It was a useless action because there were still all
the sounds. Derek’s punched out grunts and moans, the quiet murmuring words he
was pouring into Stiles’ ear, Stiles’ answering whimpers and aborted cries. A
particularly loud groan was immediately muffled and replaced with a wet
suckling noise that made her peek up.

Stiles’ head was pushed back on the pillow, his neck offered up to Derek, his
lips wrapped around two of Derek’s fingers. Allison was certain that some part
of her was actually on fire now. The back of her shirt was sticking to the
chair, same as her bared thighs that she was keeping squeezed shut.

There was a whimper hiding at the back of her throat, wanting to come out at
every wet slapping noise that rang in the small room. It shouldn’t be so hot to
watch her friend being fucked into his bed, to watch the splotches of red
blossom across Stiles’ neck and chest, before he moaned through spit slick
fingers a garbled version of Derek’s name.

Derek answered by brutally thrusting into Stiles, the sound of it making
Allison give up and push a hand between her legs, under her panties. She lasted
less than a minute, rubbing her slick against her throbbing clit a few times
before she was trembling as badly as Stiles on the bed. The whimper finally
made itself known to the world. It was embarrassingly loud. 

And if her fingers weren’t busy stretching her orgasm out for all it’s worth,
toes curling deliciously inside her boots, Allison would have run away.

Instead she rode out the blissful sensation coursing through her, watching
through heavy eyes as Derek pushed in a few more times, hands holding Stiles’
legs open so wide that she wondered at the teenagers flexibility and how sore
he was going to feel later. The last stroke was hard and deep, making Stiles’
body arch up right as Derek bowed into him. 

Allison reclined back in the chair, fingers still caught under cotton and lace,
chest heaving as she tried to catch her breath. Between one heavy blink and
another, Stiles and Derek had gone from exchanging lazy kisses to eyeing her
from their spot on the bed.

Feeling extremely self concious, she pulled her hand out from under her skirt.
And wondered how to clean her fingers. “I think she enjoyed that.” As hoarse as
Stiles’ voice was, it didn’t hide the amused lit to it. Allison blushed and
tried to glare at the teenager, who was too blissed out to do anything but grin
back.

--
She was invited to stay.

--
Allison fell back on her bed, spread eagle on top of the leaf motif sheets. She
blinked up at the ceiling and wondered if she ought to start with her Chemistry
homework first or English. A cheery bell chime made her turn her attention to
her cell phone charging on the bedside table. 

With a grunt, she rolled over and made a grab for the phone. She thumbed the
notification open. It was a new message from Stiles. Allison willed herself to
not think about the evening past or the considering manner with which Stiles
and Derek had watched her leave the room. 

Allison licked her lips and brought the new text up to the screen.

’Just give us a heads up if you want to watch again.’

--
And she does after that.
