     I OWN NUZZING.
See the end of the work for more notes
    When John Shepard was fourteen, he went into heat for the first time.

    He had known he was an omega since he was born, as most omegas do. He
remembered his mother (light brown hair, brown eyes, loving smile) pulling him
onto her lap and telling him that he was special, that one day he could be a
mommy just like her, or a daddy like his father (dirty blond hair, laughing
blue eyes, always a grin) was. He remembered her telling him that just because
he was an omega like his Aunt Rachel (in love with Aunt Illyana, who was an
asari, almost as soft and feminine as Rachel, and Aunt Jacki, who was human,
liked outdoors and had short hair because it was easier, both alphas and they
were all in love with each other, 'just like your stories' daddy liked to tease
mommy) didn't mean that he should let himself be pushed around by the alphas in
the neighborhood (Connor, 2 years older and liked to move him around like he
was a doll, Nathan was his age but taller it wasn't fair, and Paul always had
the girls following him around like that puppy John had found and given part of
his cookie).

    But then one winter Mommy got sick, real sick, and Daddy went with her to
the hospital. A truck lost control on the ice and John was suddenly alone. He
didn't want to go with the police men(don't talk to strangers, not even if they
have candy, and NEVER go anywhere with them), especially the ones who told him
his parents weren't coming home, and so he ran, away from the men, away from
the house with no mommy or daddy, away from the older woman who lived next
door, and hid, shoving himself into crevices and holes and not answering when
they yelled his name.

    It was easy to get lost in a big city like Vancouver, and other kids were
willing to teach John little tricks they had learned, like how to slip
someone's wallet out of their pocket without them noticing (Remy, reddish brown
hair, from Nohlinz or something) - because even though credits were the
official currency of the galaxy, some places still used physical money as well,
and people liked the feeling of cash in their wallet - or how to hack into an
ATM without getting caught (Charlie, red hair liked girls like Aunt Rachel but
still thought he was cute), or even stuff like how to defend himself (Alistar,
blonde and kind, always willing to help the others if they needed it) or how to
win a fight against a biotic (Morgana, elegant and commanding even as a
preteen, always with her sweet best friend and had a soft spot for cute things,
liked to teach through experience but never gave him much more than he could
take), and he did his best to pass on his knowledge to others as he grew
(Jubilee, two years younger, budding biotic, parents shot hitchhiked her way
here had to get away just like him).

    His education was mostly useful knowledge gained from friends, but
sometimes one of the s-k's (short for street kids, sounded cooler than and not
as helpless as homeless did) would find a schoolbook (find, nick, salvage,
didn't matter, theirs now), and they would pour over it, figuring out the
equations and science, discovering that "your" meant "something that belongs to
you" and "you're" was "you are", and how to conjugate verbs in french and
Tuhila, one of the asari languages.

    Gwen was a great cook, and Morgana could flirt her way out of anything, and
they could both kick some ass if they needed to. Remy was a charmer, and he
could always tell what people were thinking, and no one could catch him if he
felt like swiping him, he was too good. Charlie drew girls to her like flies,
together she and Remy were unstoppable, and she could hack her way through any
technology imaginable. Alistair could always be relied upon, was a great judge
of character, was good muscle, and wasn't nearly as stupid or innocent as
people thought. Jubilee was a decent pickpocket, too, and was young and cute
enough that nobody ever suspected her of anything, and if she got caught
stealing from a store her puppy-dog eyes and innocent omega disposition usually
not only got her out of trouble but also got her whatever she had been trying
to take in the first place, sometimes even something else too. John wasn't as
smooth as Jubilee was, but he was still smallish, good at hiding, a decent
hacker, and perceptive. It was a unique family, but it worked for them.

    John and Jubilee were helping Charlie with one of her "missions" (she liked
to call them that) when it hit him. He hadn't realized what was happening at
first until a nearby alpha pulled him against her already hard cock, tearing
his hand from Jubilee's and crowding him against a nearby building. Part of his
mind panicked, while another part screamed 'YES!' Even though he agreed more
with the panicking part, his body had a different idea, and he was suddenly
aware of a slickness seeping from his virgin hole and a growing ache, an
emptiness begging to be filled.

    John snapped back into the present at the sound of Jubilee yelling as she
darted in, arms slamming ineffectually against the alpha pinning John to the
wall. Her screams of "LET HIM GO!!!" had little effect on the alpha nipping at
John's throat. He couldn't quell the moan that escaped his throat even as he
half-heartedly pushed at the alpha's shoulders, trying to bring himself to
resist. He didn't have to for long, however, as Charlie ripped the alpha off of
him, pushing John towards Jubilee as she started yelling obscenities at the
woman. Shaking his head, John stumbled after Jubilee as she dragged him away
from the crowd. His head cleared slightly and he picked up the pace, pulling
Jubilee into an alley before darting through a side entrance to a museum.

    They tore through the museum, darting around exhibits and people alike
(though John picked up a few followers too, unfortunately), not stopping even
when security yelled at them to. When they reached the entrance, John grabbed
Jubilee's hand, sprinting past the crowd and through the doors before making a
sharp left. As they headed toward a quieter part of the city, Jubilee's hand
slipped from the older omega's. He whipped around, but Jubilee shook her head.
"Go!" she panted "I'll delay them!! Hide and then meet up at base!" Base was
their home, a tiny run-down apartment in a building that had somehow been
missed by inspectors. He nodded and spun back around, taking off again as fast
as he could. He had gotten a fair distance away before the hair on the back of
his neck prickled, naturally attuned to Jubilee's (and Morgana's) biotics.
Pushing his legs even faster, he grabbed a sign post, using his momentum to
swing him around it 90 degrees before releasing it. Behind him, he heard the
crackling BOOM of Jubilee's biotic "bubble" ('like a shield, but then push
out,' Morgana instructed the asian-american girl in front of her) shoving
everyone away from her. Hope she gets away gets home safely need to hide need
to hide NEED!

    John raced around an older library (closed for renovations, haven't started
yet, good place to hide if I can pick the lock gotta FOCUS!) and let out a
relieved gasp at the sight of an electronic lock, easily bypassed if you knew
what you were doing (and he did, he did, thank you Charlie, genius yes thank
you thank you). The ache in his body was growing, but John managed to focus
long enough to push the door open and stumble through into the strangely sparse
library. He gave the door a light shove, most of his mind focused on getting to
that couch over there and undoing his pants now.

    He had barely reached the couch when a bigger hand grabbed his shoulder and
spun him around, a very male mouth crashing down on his. The man's hand cradled
the back of his head, other arm curled around John's waist. Then the lips left
his, causing him to let out a high-pitched keen as he tried to follow the soft
lips. When had his hands fisted in the man's shirt? Foreheads touched, and
John's eyes fluttered open to see the alpha. The man looked to be in his late
teens, a hint of stubble on his strong jaw. His skin was several shades darker
than John's own, dark eyebrows over eyes that were clenched shut.

    "Tell-- tell me to stop," the raspy voice managed to get out. "Tell me
stop, and I will." Honey-brown eyes opened, looking directly into John's own as
the alpha struggled to control his instincts. Despite never seeing the elder
before, despite not knowing where he came from, who he was, or what he was
capable of, John somehow knew the man wouldn't hurt him. Not fifteen for a few
more months, John still had yet to hit his growth spurt and was more on the
thin side than anything, while he could feel some definition to the muscles
under the much bigger alpha. The man could take what he wanted from John even
if John wasn't nearly mindless with need, and yet even as his instincts were
screaming at him to fuck the omega, claim him as his own, he stopped and waited
for permission. John felt a brief rush of power at the realization that it was
his choice, he was in control, followed by a wave of arousal so large it
threatened to pull him under, drowning him. Decision made, he opened his eyes,
meeting the desperate amber gaze.

    "Please…" he whispered hoarsely, then gasped as the man shoved him onto the
couch, ripping his own shirt over his head. Moaning, John reached for the man's
zipper, managing to get it undone before the alpha's hands grabbed his smaller
ones. His gaze shot up to meet the man's, confused.

    "Kaidan," the man stated, eyes flickering between John's. It took the omega
a minute to understand that he was telling him his name.

    "She-- John," he replied, trusting the alpha - Kaidan - with his name.
Kaidan's eyes held his a moment longer before he nodded, then suddenly, the
elder's body was covering John's, lips and tongue demanding entrance to John's
mouth. He gasped, then whimpered at the invading tongue seeking out ant
dominating his own. A part of his brain vaguely registered that Kaidan was
doing something to his legs, but every functioning synapse was focused on the
way the alpha was claiming his mouth. John gasped sharply as his mind
registered cool air on his sopping hole and looked down, confused. Kaidan took
this opportunity to pull John's shirt over his head, trapping his arms as he
pinned the smaller male to the couch, grinding against his nude body. He
attacked the omega's neck, intent on replacing the marks left by the female
alpha with some of his own. John heard a high-pitched whimpering sound, but it
took him a couple minutes to realize it was coming from him as he squirmed on
the other's lap, held there by strong hands on his hips and his own arms
clutching the bigger man to him, one hand buried in the curls. Not ENOUGH.

    The hand not buried in the alpha's hair retreated, reaching underneath his
body in an attempt to reveal the treasure still hidden under pants, the prize
his body was aching for. Kaidan gasped as John's hand found its target,
releasing the skin he had been torturing with his mouth. The groan that then
resulted from the elder sent shivers through John's body, causing his hand to
reflexively twitch. Kaidan inhaled sharply before tightening the grip he had on
John's hips and stood up. The hand buried in Kaidan's hair quickly switched to
his shoulders, legs wrapping around the man's hips and locking together at the
ankles. One of Kaidan's hands moved to grasp John's ass, mouth attacking his
again while his other hand quickly divested himself of pants and underwear.
John tried to direct Kaidan's length into him, whimpering when the alpha jerked
him away. John was placed on the couch almost reverently, the elder man then
kneeling between his legs. Gently, Kaidan pushed a finger into the slick
opening, causing John to arch sharply with a gasp. John heard the other chuckle
hoarsely as the finger thrust in and out a couple times before withdrawing
completely. He didn't even have time to complain before two fingers breached
him, brushing against something that almost made him convulse with pleasure.
His cock was covered by another hand as the fingers inside him started
stretching him apart, far too slowly for his taste. He tried to convey his
distaste for the pace the alpha had set, but he wasn't sure if he managed to
actually get the words out or just babble incoherently. John whimpered as
Kaidan added another finger, mouth reattaching itself to his neck and hand
jerking him off slowly, nearly driving him insane with pleasure.

    Finally, Kaidan stopped the unbearably wonderful torture, and moments later
John felt a blunt pressure pushing against his entrance. He nearly cried as the
man did nothing, just held himself at John's entrance. A part of John's mind
noticed as he started begging and pleading, promising anything--

    Kaidan slid in.

    He felt so full, so amazingly stretched and filled, and he wondered how
other omegas were ever able to do anything when this felt so wonderful.
Kaidan's lips met his, almost gently this time. John let the alpha kiss him
sweetly until he felt he would burst, wiggling his hips slightly and causing
Kaidan to freeze for a moment. The next, he was gripping John's hips tightly
and pounding into him, working more and more of his cock into John's eager
body. Kaidan's tongue ruthlessly speared into John's mouth, mapping every
millimeter of it as the omega eagerly kissed back, doing his best to meet his
alpha's thrusts.

    Kaidan's mouth finally left his, sucking and laving the junction of his
neck and shoulder. As the man finally wrapped a hand around John's weeping
length, he bit down hard, hips slamming in, causing John to cry loudly as he
came. Kaidan milked the orgasm from John's cock, then wrapped the hand around
John's hip again before thrusting in a couple more times and coming himself,
teeth still buried in the omega's shoulder, binding them together as his knot
inflated making their connection physical as well as spiritual. His hips gave a
few more tiny thrusts as his knot fully inflated before stilling, holding the
still-gasping boy to his heaving chest as he turned them, sitting down as his
mouth released the omega's shoulder.

    John curled into his alpha, pleasantly sated for now, and gazed at the
man's handsome face. Kaidan then sat up suddenly, eyes snapping open with a
stricken look on his face as he stared horrified at the wound he'd left on
John's shoulder. John knew why the man was horrified - he had just permanently
bound their souls together, without even asking permission first. Still, he
couldn't really bring himself to mind, finding the tingle of the man's presence
at the back of his mind pleasantly soothing. He resettled himself on Kaidan's
chest, intending to get some rest before Kaidan's knot deflated and his heat
needed to be satisfied again.

    Thank you, my alpha, he whispered into the other's mind, smiling slightly
when Kaidan's body relaxed at the intrusion.
End Notes
     yay! I may add more later, such as a companion piece from Kaidan's
     POV or continue on and see how this bond Kaidan accidentally forged
     between them affects their lives.
     John's going into his first heat came shortly after Kaidan's return
     from Jump Zero, as he is desperately doing his best to control
     himself. This (along with his strong morals) are what helped him hold
     back until John gave his permission. He is not yet 18. The fic is so
     named because if the timing had been different - John had gone into
     heat a few months earlier like in Street Rat, Kaidan would still be
     in Brain Camp/at home in the immediate aftermath of Vyrnnus's death,
     and would not be able to react as he does here. Also, if he had been
     a bit slower investigating Jubilee's biotic blast, he would not have
     noticed John.
     As for the rest of John's "family", i was trying to add characters
     that would have different talents and could plausibly live on the
     streets. Remy (Gambit from the x-men) was my first addition. He is a
     talented thief and (depending on who is writing him) an empath. Next,
     I wanted a biotic, and nearly chose Merlin, but decided Morgana was
     better, as she's tougher and can really kick ass. Along with her came
     Gwen, her gentle and loving best friend. (and before you protest that
     Morgana is a princess and would not be able to handle living on the
     streets, may I remind you that she was Uther's ward, and had not
     always lived with the Pendragons. Lastly, I wanted someone young and
     innocent, but who was also street-smart (and I kinda wanted another
     biotic that Morgana could teach). Suddenly, Jubilee (x-men) sprang to
     mind, and fit in with the rest of the family like a missing puzzle
     piece. And thus the family was complete!
