Summary
     Jeff recognizes them as the pair that sat in the back of his third
     period class, desks shoved together and chairs practically attached.
     From the corner of Jeff’s eye, he would catch their movements
     throughout the entire lesson, always touching. The only real distance
     between them were their names on the roll call: Ackles and Padalecki.

Jeff flicks the lights off, shutting the door to room 126. He walks down the
hall, students milling around him, filing into their final classes of the day
before the bell rings. The lockers along the walls are still the grunge-green
from his teen days, the linoleum floors greying from years of sneakers and
scuffs.
Discretely opening his cigarette carton as he turns down another familiar
hallway, he huffs a laugh. At seventeen, tagging school walls behind the
dumpsters, he’d never imagined himself back here, introducing himself as Mr.
Morgan. Norm had called in a favour though, delayed in the next state over –
motorcycle problems – and Jeff agreed to drag his own ass out of early-
retirement to cover his friend’s classes.
From the faded neon orange paint trailing across the brown exterior, the school
hasn’t been able to successfully wash off the graffiti. Jeff steps outside,
following the marks around the corner, lighting up as he approaches his old
secret spot, an alcove out of sight from the sidewalk leading to the football
field.
A gasp and moan stops Jeff in his tracks, and his wolf hones in on the sound.
Now that he’s paying attention, the waft of omega-scent hits him, and the
corner of his lips lift in the beginnings of a growl. There’s an open window
overlooking the alcove, giving Jeff a perfect view of a squirming boy bent over
a desk, crying out as a larger teenager plows into him.
The slender fingers clutch at the edge of the tabletop, shirt shoved up to his
armpits and jeans trapping knees that are valiantly struggling to spread
further apart. Fuck. Jeff can see the omega’s shoes lift off the ground with
each thrust.
Slowly, he approaches the window, the sounds of the boy’s breathy moans loud
and clear. Jeff lowers the cigarette between his fingers, keeping it lit to
mask his scent. The window ledge is waist high, and Jeff can crouch down just
enough to avoid being seen. Though he doubts the thoroughly preoccupied couple
would notice, watching as their tongues tangle in a messy open-mouthed kiss.
With a small jolt, Jeff recognizes them as the pair that sat in the back of his
third period class, desks shoved together and chairs practically attached. From
the corner of Jeff’s eye, he would catch their movements throughout the entire
lesson, always touching. The only real distance between them were their names
on the roll call: Acklesand Padalecki.
Even from afar, he could tell the omega, Ackles, was a stunner – short, blond
hair and a sweetheart-pink mouth that smiled when Jeff called his name. When
Padalecki had been called upon, the shaggy-haired teen sat up straighter as he
raised his hand, narrowing his eyes at Jeff in typical, cocky alpha challenge,
before deliberately lowering his hand onto Ackles’.
As if their entire set-up didn’t already scream mine.
From class, Jeff hadn’t realized how damn tall the kid actually was, easily
blanketing Ackles over the desk with plenty of inches to spare. Ackles is
struggling to shove back, but Padalecki is keeping his hips at bay.
“Jensen.” It’s strained, hot with arousal. Padalecki pulls back, hand firm on
the small of Ackles’ back, dick holding him open. “Jen. You smell so damn
good.”
“Jared. Jared – fuck,please.” Jensen wiggles desperately, and Jeff’s caught on
the sight of enticingly round cheeks. “Knotmeknotmeknotme – alpha –“
There’s a pained sound when Jared pulls back, big alpha dick slipping out,
dripping in slick. Jeff can see where the would-be knot of a fully-grown alpha
would be, a slight swell at the base of his dick. Most don’t fully develop
their knot until their late teens, but with a needy mate in the picture, Jared
will likely be sporting his in no time.
Jensen sags against the desk in disappointment, breathing hard. Jared hauls him
up into his arms, trying to press consoling kisses to the omega’s body. “You
know I want to, Jensen. Once I get my knot and my teeth, it’s gonna be you and
me.”
It’s a wonder to Jeff that the young alpha can even control himself in the face
of his willing, begging omega. After a few moments, a few more kisses, Jeff
sees the tuft of Jensen’s head nod. The boy sinks to his knees, taking the hard
dick into his mouth. Jared’s hands frame the sides of Jensen’s head, guiding
Jensen to take his cock deeper and deeper.
“God, Jensen… yeah – so good for me…”
Jeff wishes he could be close enough to see the jump of the omega’s throat as
he strains around the entire girth. They finish quickly, Jensen’s hands moving
over the premature knot, drinking what he can of his alpha’s come, the rest of
it escaping in sputters down his chin, Jared practically doubled over in his
pleasure.
After pulling away, Jensen murmurs a few words, and Jared’s expression warms
even more than before.
Jared lovingly wipes the trails of white off his boyfriend’s face, kissing him
fiercely once again. He pulls away with a dark gaze. “Meet me after practice,
I’ll make it up to you, okay? It’s gonna be soon. I can feel it, I swear. I
want to knot you so fucking bad, Jen. I can’t wait - want you hanging off my
dick all night, gonna make you take it over and over.”
Jeff watches Jensen shudder in Jared’s arms, takes in the way their pheromones
shift and respond to each other. In all his years, he’s never seen a pair so
strongly matched. They aren’t officially mates yet, but Jeff has no doubt these
two will be sporting each other’s bites in a few years.
His inner-wolf growls, lonely and restless, tinged with longing. He’s had his
knot in plenty of omegas, but Jeff’s never mated any of them. Doubts he’ll ever
hear that call for himself.
That might explain why Jeff’s still waiting by the window, watching as the
couple kisses one last time, before Jared slings his duffle over his shoulder
and hurries out the classroom door.
Finally, Jeff drops the cigarette and crushes it beneath his foot.
“Quite the responsible alpha you’ve got there.”
The omega startles, turning around as Jeff swings his legs over, climbing
through the window.
“Mr. Morgan – I –“ Jensen scrambles back, eyes wide and face flushing with
embarrassment. He’s aware the room is perfused with sex, self-conscious of how
freshly-fucked he must smell.
The boy’s still half-dressed, pants pulled up but shirt still gaping open. Jeff
can see the deeper reds and possessive purples of bite marks all over the
omega’s torso.
Owned. Do not touch.
But Jeff wants.
He’s never been good at following rules.
“Didn’t get the knot you wanted though, did you, boy?” Jeff backs Jensen up
against the desk he’d just been fucked on. The boy quivers, and Jeff feels smug
– he knows how to hit the gruff notes that make omegas want to bend over for
him. Jensen’s still hard, still radiating neediness – the promise of a knot
making the green of his eyes disappear in desperate black.
“No – it’s. It’s none of your business,” Jensen says, but his breath is
shallow, his wet, pink mouth can’t quite shape the word ‘stop’, and he looks
like he’s a second away from begging.
“That’s between my mate and myself.” The delivery is firmer this time, the
smoke of conflict mixing in with the scent of lilies and honey. Jeff isn’t
playing fair. “I should go –“
“He isn’t really your mate yet, though…” Jeff says, running his hand down
Jensen’s chest, resting at the yet unbuttoned crotch. He leans in close,
pressing his still-clothed alpha dick up against the gap in the boy’s pants.
Jensen whimpers and thrusts involuntarily upwards, throwing his head back and
letting Jeff nose along the pale, freckled skin of his neck. The omega-scent is
strong, and Jeff drinks in the boy’s desperation. “And besides, he’s not very
good at protecting what’s his. Left you ripe for the taking.”
“We aremates –“ Jensen protests, but his voice falters, breath hitching as he
tries to resist the weight of Jeff’s commanding presence. The fact that his
body is responding so strongly to Jeff proves his statement wrong, and he knows
it.
He pushes Jensen back onto the desk. Peeling the boy’s pants and underwear off
as he goes, revealing lithe bowlegs and a pretty, little omega dick. He unzips
himself as well, tugging his own underwear down enough to free his aching
erection. Jensen keens at the sight of it, legs spreading even further on
instinct.
The sight of the little hole, dark pink and slightly swollen from its previous
encounter, shiny with omega slick, makes Jeff groan before ducking his head
down for a taste. His large hands gripping Jensen’s thighs, holding them apart,
feeling the muscles in his legs twitch with every scrape of his stubbled jaw
across the hypersensitive skin. Tonguing the shivering hole, Jeff eagerly laps
up the taste of syrupy honeydew, his wolf growling at the slight tang of
another alpha.
“Mr. Morgan –“ Jensen moans, sweet song with his head hanging off the edge of
the desk, barely able to hold it up through Jeff’s attentions.
 Jeff pulls back, flipping the boy so he’s bent over the desk again. He traces
the slippery entrance with his fingers. Tips teasing as they sneak inside then
slip out.
“Want my knot, omega? Want to be stretched open and plugged full of come?”
There’s a whole-body shudder as the boy lifts up to the tips of his toes,
angling that ripe peach of an ass for Jeff.
Fuck, if he hasn’t found the sweetest damn omega in town.
He lines himself up, pausing before sinking in to watch the omega hole forced
open for the unyielding girth of his alpha dick. The boy keens at the intrusion
as Jeff pushes forward. From Jensen’s shocky, breathless gasps, Jeff is
reminded that the boy’s never been fucked by a fully grown alpha before. A dark
current of satisfaction settles in his belly, making him more eager to break
Jensen in.
Watching the dark rouge of himself disappearing inch by inch into the young
omega, Jeff relishes in every spasm of tight heat around his dick. One quick
thrust buries him the rest of the way inside, earning a strangled squeak from
the boy. His fingers find where they are joined, entrance taut and trembling
around his cock.
 “Oh – god, oh - oh –“ Jensen’s hands clutch at the desk, legs restlessly
moving further apart in an attempt to entice Jeff to keep going, trying to
please the alpha.
Each movement of his hips is heaven, Jeff quickly becoming obsessed with
carving out a space for himself inside this boy. Jensen moans and begs so
sweetly, his pink, open mouth singing for the thrusts that sink deep and hard.
“Still so tight, even after getting fucked by your boyfriend,” Jeff growls,
snarling at the thought of his competition. Jensen’s eyes are glazed, but he
still flushes with shame, guilt-scent strong in the air.
“So eager for it. One mate probably isn’t enough for you.” That startles Jensen
enough for him to try to pull away, but Jeff drags him back, rough thrusts
dissolving the boy into a series of jerks and loud yelps. Jeff knows how
scandalous his words are; any suggestion of cheating once truly mated is
blasphemy.
“No, no, no – I love h- I just. Please. I need it. Please knot me –“
Jeff grins, all teeth. Lucky for him, he’s caught this omega before he’s been
claimed by the mating bond his teenage alpha no doubt intends to place on him.
“Oh, sweetheart, you’re going to get my knot, don’t you worry.”
For now, he’s Jeff’s.
His knot starts to swell, the bump of it catching on Jensen’s hole, and Jeff
slows his thrusts enough to watch Jensen take the growing knot, the edge of his
hole straining to accept him.
Gasping and moaning, Jensen is mindless with need, back on the tips of his
toes, ass up and out, trying to take all of him.
The slick makes his knot pop in as soon as he breaches the widest point, and
he’s locked in. That’s enough for Jensen to cry out and twitch helplessly, his
hot, slick ass clenching around Jeff and come splattering the desk and the
classroom floor.
Jeff carelessly uses his larger size to pin Jensen against the desk, keeping
the omega still as he pumps him full of come. The boy allows himself to be
smothered, senses lost to the feeling of being bred, at the mercy of an alpha.
Contentment and possessiveness rise up within Jeff, and he runs alpha fangs
along Jensen’s smooth, bare neck, rubbing the omega’s trembling belly, where
Jeff is filling him up.
Such a temptation.
They stay that way for almost ten minutes, just before the very last bell of
the day. Jeff regrets the loss of tight, wet heat, abused entrance turning
slightly out as he drags his dick back. He thumbs the swollen opening, pleased
at the mess he’s made of the boy, come and slick leaking copiously out of the
hole before Jensen can scramble to get his pants back on.
Jensen, shame-faced and radiating guilt, smells entirely of Jeff.
“Better go find your boyfriend, sweetheart. Wouldn’t want him to worry.”
He leans back on the desk behind him, not bothering to do up his pants, dick
still out and dripping as Jensen yanks his shirt back down and quickly gathers
his things.
There’s a pause at the door, and Jensen glances back at Jeff one last time,
before hurrying out of the classroom, door shutting behind him.
It isn’t until he’s alone, reveling in the lingering scent of breeding that he
finally notices the writing on the chalkboard.
‘Biology.’
Jeff smirks. Maybe it’s time for him to take up teaching again. He just gave
one hell of a lesson.
