***** Chapter 1 *****
Derek still didn’t understand how his loft had become infested with teenagers
on a daily basis. By all accounts it didn’t make sense. It was lucky the
sheriff was in the know about supernatural creatures or he’d probably be very
suspicious about why his teenage son and co were hanging out with suspected
murderer Derek Hale. Sure Derek wasn’t that much older than the rest of the
pack, excepting Liam who was just a baby, but it was still against the social
norms.
Maybe it was because Derek was the legal guardian of four of the teens, five
plus Malia.
Derek sighed heavily and scowled at the swarm of children in his living room.
Erica and Boyd were cuddled up on the loveseat with Allison and Isaac and
sharing a giant tub of cheese puffs. Erica growled lowly whenever someone stuck
their hand in at the same time as her. Stiles was spread out over the blue
velvet couch, hissing slightly whenever someone tried to sit with him. It was
weird. Derek supposed that’s why it worked in getting everyone, even Scott to
back off. Stiles smiled into the couch cushions and complained loudly about the
crappy sitcom they were watching.
Scott and Kira were huddled together on Erica’s zebra stripped bean bag chair
that she usually did her homework on. they were being disgustingly cute and
adorable and it made Derek slighlty sick. Lydia and Cora were having a rather
intense chess match, Malia watching in facination. Derek shuddered at his
sister and the banshee; that was a combo that would make even the Alpha of
Alphas turn tail and run. Stiles snorted softly and Derek frowned in confusion
before going back to study everyone.
Ethan, Aiden and Jackson were having a wrestling match in the empty space
between the living room and kitchen. ‘Fucktards’ he thought and rolled his eyes
searching for Liam and Mason finding them playing video games on Scott’s laptop
with Danny. Liam twitched slightly every time there was a loud bang from the
douche squad in the back. He was lucky his ptsd was from Beserkers and not
killing your own girlfriend, as Derek’s had been at 15.
Peter was off doing something creepy and douchey and Derek really didn’t want
to think about it too much. Stiles snorted again and Derek looked at him,
confused. Stiles shrugged like the nonchalant little bastard he was and smirked
again. Derek’s eyes narrowed. After a while Stiles got bored and started
picking at the scabs on his arm.
They’d had a run in with a few witches and Stiles was literally the only one
that got scratched. The boy seemed to be his own sort of supernatural beacon.
Derek looked up to see Stiles scowling at him. He smirked and turned back to
his book. Stiles had claimed that it was just a scratch and had no negative
side effects. Everyone had believed him but Derek. Derek knew it irked the kid
but he couldn't help it. He knew that Stiles had learned to control his
heartbeat, living with wolves.
But Stiles’ smell sort of twinged when he lied. And when he didn’t lie but
avoided certain truths…it got sharper momentarily. Derek was embarrassed by how
in tune he was with Stiles’ sent. He doubted even Scott was this in sinc with
it. Stile’s sent spiked with curiosity and confusion, and always the undertone
of arousal, before he stamped it down. Derek’s eyes flickered to him curiously
but he was studying the tv furiously.
Derek shrugged and turned back to his book, bored out of his fucking mind.
Erica and Boyd had started sucking face and Derek growled at them until they
pulled apart, spit line linking their lips. He let his eyes flash at them in
warning before ignoring them. He knew they were horny teenagers and that there
was nothing he could do to about whether or not they had sex. Except soundproof
every single damn room in this whole building, stock the cupboards with condoms
and enforce rules about excessive pda in public. If they wanted to mate they
could go to their room.
Allison and Isaac looked like they were equally disgusted and aroused at the
other’s display of heavy petting and face sucking. Derek was seriously
considering kicking them out if he smelt any more arousal coming from any of
these teens.
“Who wants pizza?” Stiles chirruped and immediately 15 hands shot into the air.
Stiles turned to Derek with a wicked smirk. “C’mon old man. It’s gonna cost a
small fortune to feed all of us, you’re the only one with money…”
‘I’d pay money just to get you shut up’ Derek thought, scowling and tossed him
two twenties from his wallet. Stiles smiled the smiled that made Derek’s heart
flutter, said smile only grew wider, and flounced out of the loft. The
remaining teens gathered around the enormous dinning room table and started
jabbering incessantly. Derek rolled his eyes and let his mind wander to
thoughts of Stiles.
As always, thoughts of Stiles led to thoughts of the wicked things he’d like to
do to Stiles. Bend him over the dinning room table and fuck him roughly. Take
him apart piece by piece on the fur rug in the living room. Knot him right
against the sliding metal door. Eat him out for hours while Stiles tried and
failed to do his homework. Let Stiles fuck him so hard the bed springs
screamed. Have Stiles blow him while he ate him out? That one was always
Derek’s favorite. God the things that Stiles could probably do with that mouth.
Dimly, in the middle of a vivid fantasy of opening Stiles up with four fingers,
he noticed the door sliding open to reveal the boy himself, holding a leaning
tower of pizza. Scott and Malia instantly took the boxes from Stiles to reveal
his face as red as a tomato. Derek raised an eyebrow at him before quietly
saving his fantasy of knotting the boy for later. Stiles shuddered and joined
the others for pizza. Derek walked over to grab a couple of slices before the
hoards could descend up them.
He stood behind Stiles, and reached around him to grab a plate and fill it,
noting how Stiles tensed and blushed violently. His sent colored in
embarrassment and Derek smiled. God how he loved how Stiles smelled. Stiles
looked at him in pure confusion as Derek continued in his quest for dinner.
“What?” Derek asked around a mouthful of pizza and Stiles just stared at him,
pouting. Derek’s eyes flickered to his lips before he looked impassively at
Stiles again. He’d learned long ago to control his face, sent and heart rate,
allowing him to think dirty things in public without anyone or thing knowing.
Currently it was helping him fantasize about those damn puffy lips.Stiles
squawked and turned back to the pizza, stabbing Jackson with a fork in order to
get some.
Stiles was acting weird…Well weirder than usual.
‘If you’re a mid reader cough twice’ Derek thought sarcastically to himself as
he rummaged through his fridge for some ranch dressing. He’d learned to control
himself but sometimes that didn’t help. He knew of people that could read minds
and sometimes it worried him. But he seriously doubted Stiles was one of them.
Two pointed coughs.
Derek whipped around to stare at Stiles in horror. Stiles smirked at him and
winked before flopping onto the beanbag and began scarfing down his pizza.
Derek sat in the kitchen and ate in quiet horror, watching the teen smirk at
him, wondering how long he’d been able to read minds. Stiles held up two
fingers and mouthed “weeks.” Derek blushed and recalled how many times he’d
fantasized about the beautiful teen. Stiles smirked again, blushing and turned
back to the tv.
To be continued....
***** Chapter 2 *****
“I don’t know whether to be angry at you for not telling about the mind
reading, or to be violently embarrassed.” Derek sighed heavily when the rest of
the pack had left. Boyd and Erica lived on the third floor of the building,
Cora and Malia lived on the fifth, Derek on the sixth. Stiles smiled and picked
up a leftover piece of pizza. Derek was actually surprised that there were
leftovers.
 
“Well…” Stiles said around a mouthful of pizza. “I don’t want you to be angry
and while I do love making fun of you…I don’t want you to be embarrassed
either.” Derek marveled at Stiles’ show of maturity before sighing.
 
“Says the boy who probably heard countless fantasies about an older man
sleeping with him.” Stiles shrugged and filled a glass of water for himself and
one for Derek.
 
“Yeah…that seems to be your biggest hang-up, the age thing.” Stile said,
sliding into a stool next to Derek. “You know I’ve had sex before right?”
Stiles asked, looking at him curiously.
 
“Yes, Stiles I do remember the period where you and my cousin were going at it
like rabbits.” Derek drawled, stealing Stile’s slice of pizza. Stiles pouted
and Derek’s eyes instantly went to his lips.
 
“So…” Stiles breathed out, blush coloring his cheeks. “I didn’t know knotting
was a real thing.” Derek paused, cup at his lips. Derek raised an eyebrow,
wondering if there was a point to this, and took a sip of his water. “Explain
it to me.” Stiles demanded.
 
“I’m not explaining ‘werewolf sex’ to you Stiles.” Derek grumbled.
 
“Is knotting a mating thing or is it just an ‘every time’ type of deal? I
figure its more for breeding purposes like a regular know but you know I dunno.
What does it look like when it’s not swollen? Is that awkward when you sleep
with a human that doesn’t know? I mean obviously it wasn’t when you slept with
my evil English teacher. But then she did know…” Stiles rushed out in one long
breath. Derek blinked at him in shock.
 
“What?” He asked stupidly. Stiles scowled at him and he sighed, thinking back
to the other questions. “Well…my dick just looks like a dick when there’s no
knot. The knot just…appears I guess, during sex. But then only rarely. I’ve
never knotted anyone myself…because yes it is a ‘mating thing.’” Derek huffed.
 
“But you thing about knotting me?” Derek froze. “Do you do claiming bites when
you mate?” Stiles asked, already bulldozing on. “Because Malia bit me during
sex once, said she was trying to mate me.” Stiles shuddered. Derek tilted his
head in question. “You don’t just mate someone without their permission!”
Stiles said, flailing his arms about.
 
“Is that why you broke up?” Stiles nodded, stealing the pizza crust from Derek
and nibbling on it. It all felt terribly domestic, eating pizza and discussing
sex with Stiles. Derek wanted more of it. Stiles smiled at him and he cursed.
 
“I want it too.” Stiles whispered, blushing. Derek blinked in shock and could
smell the tentative hope rolling off of Stiles. Derek groaned, want spiking his
veins.
 
“You’re seventeen Stiles.” Derek groaned. Stiles frowned but his sent
turned…contemplative.
 
“If I call my dad and ask permission will you sex me up?” Derek blushed scarlet
and looked away, imagining that conversation with the Sheriff. Stiles snorted
and pulled out his phone.
 
“I didn’t say yes!” Derek protested but Stiles’ dad was already answering the
face time chat on his office computer. “God.” Derek groaned into his hands.
 
“Yo daddy!” Stiles smiled.
 
“What do you want Stiles?” The Sheriff raised an eyebrow in a no nonsense type
of way. Derek smirked into his hands.
 
“I hope you’re not in polite company!” Stiles sing songed. A sigh. And then:
 
“Parrish we’ll talk later.” Derek looked up through the cracks in his fingers
as Parrish leaned into the camera view.
 
“Hey Derek.” He waved before leaving.
 
“What now Stiles?”
 
“As you know, I am a sexually active teenager,” Stiles placed his hand over his
heart and the Sheriff groaned. And ran his hands through his thinning hair.
 
“Is there a point to this?” he sighed, exasperated.
 
“I want to have sex with Derek but he’s too chicken shit because I’m a minor.”
Stiles explained. Derek blushed. To his surprise the Sheriff turned to him.
 
“He’s not coercing you is he? Blackmail? I wouldn’t put him above blackmail.
Just say the word and I’ll stick him in here for a few hours.” Stiles pouted
and Derek grinned widely.
 
“Derek’s the one that won’t sex me.” Stiles muttered. The Sheriff waved a hand
at him dismissively.
 
“No sir, he’s not blackmailing me.” Derek blushed.
 
“You honestly want to sleep with my son?”
 
“Geez Dad, no need to sound so surprised.” Stiles muttered, embarrassment and
slight hurt coloring his sent.
 
“Yes sir.” Derek said again. The Sheriff blinked at him a few times before
pointing his finger at Derek.
 
“He can’t get pregnant can he? Or get some kind of I dunno, werewolf STDs?”
 
“No to both,” Derek laughed. “Werewolves can’t carry diseases and Stiles’ is
human he won’t get pregnant.” The Sheriff nodded thoughtfully while Stiles
grumbled about being labelled as a bottom. “Stiles, Malia spooned you.” Derek
said pointedly. Stiles huffed a breath of air and turned back to his dad,
pouting.
 
“Daddy, say yes. I wanna have super werewolf sex!” John groaned and rubbed his
hand down his face tiredly.
 
“Fine.” Stiles was practically buzzing in excitement. “Derek, come over for
breakfast tomorrow.” Derek nodded and the Sheriff pointed at Stiles. “I’m
getting real bacon and sausages for this shit.” Stiles nodded enthusiastically
before shutting off his phone and tossing it into the mass of paper plates and
pizza boxes at the dining room table.
“Derek sex me!” Stiles demanded before grabbing Derek’s face and pulling him in
for a very thorough kiss.
 
“You don’t waste any time do you.” Derek gasped, leaning his forehead against
Stiles. Stiles beamed.
 
“I’ve waited years for you to notice me.” He gasped. “I don’t want to wait any
longer. Been planning this since your first fantasy I overheard.” He said
tugging Derek over to the bed. “Please tell me you have lube.” He whispered
before planting another kiss onto Derek’s lips.
 
“I’ve wanted you so long.” Derek muttered, kissing down Stiles’ neck and
nipping at his shoulder. “God, every time I see you I get so…” he groaned in
frustration, ripping off Stiles’ stud muffin shirt and continued kissing down
to Stiles’ nipple. Stiles groaned as he licked it before nibbling slightly.
 
“God yes.” Stiles moaned, grabbing the back of Derek’s shirt and pulling it
off. Derek helped him and then resumed his task, attacking Stiles’ other
nipple. Stiles’ fingers carded through his hair and pressed him closer, back
arching into Derek’s hold. Stiles whimpered as Derek licked up his throat to
kiss him again. They both moaned into the kiss, hands exploring each other’s
chests.
 
“God, every time you weren’t wearing a shirt.” Stiles gasped nipping at Derek’s
ear, sliding his hand down Derek’s front to grab the bulge in his pants. “Hnng.
Wanted you so bad.” Derek growled slightly and pushed Stiles back onto the bed,
opening his belt and dragging his jeans away.
 
“I should have known you’d be mouthy in bed.” He mumbled against Stiles’ chest,
kissing the spattering of moles there as he tossed away the boy’s jeans. The
witty remark Stiles would have made turned into a whimper as Derek mouthed over
his erection through the fabric of his boxers. Stiles groaned and threw his
head back as Derek sucked on the tip of his cock, laving at it with his tongue.
 
“Get. Naked.” Stiles panted. “Stop. Teasing.” Derek smiled, sitting up to work
on his own belt. He rolled to the side and shimmied his pants off onto the
floor. Stiles moaned when he saw that Derek wasn’t wearing anything underneath.
Derek didn’t give him much time to admire his package before rolling back on
top of the boy and nuzzling his cock. Stiles arched up into the tight wet heat
of Derek’s mouth before hissing as Derek pulled away.
 
Derek hooked his fingers in the elastic of Stiles’ briefs before dragging them
away. Stiles hissed as his cock was exposed to the cold air of the loft.
“Gorgeous.” Derek whispered before swallowing him down. Stiles whimpered as his
heat engulfed him and Derek hollowed out his cheeks. Derek held down Stiles’
hips after he involuntarily bucked up into that tight cavern. Stiles moaned
when he realized that Derek’s nails had turned to claws and the eyes looking up
at him were glowing blue.
 
It was over embarrassingly soon as Derek began to work Stiles’ cock. His balls
tightened and he shuddered out his release, one hand digging into Derek’s hair
and tugging to warn him. Derek hummed, pulling Stiles closer as he milked the
boy’s release from him. Derek mewled pitifully when it became apparent that
Stiles had spent his last drop. He looked up at Stiles, pouting and Stiles
laughed, pulling him in for another lewd kiss.
 
“There’s always more where that came from.” He panted. Derek smiled into the
kiss and nipped at Stiles’ lips.
 
‘I love you.’ He thought, licking at Stiles’ neck and Stiles mewled, pulling
back to look at Derek’s kaleidoscope eyes.
 
“Do you mean that?” Derek blinked at him in confusion before remembering
Stiles’ newfound ability to read minds, and blushed. He ducked his head into
Stiles neck and rubbed his face, scenting him. Stiles shivered at the feel of
Derek’s stubble against his sensitive skin. “Because,” he swallowed. “If you
did…I do to. Love you , I mean.” Derek pulled back to look at him in shock
before smiling brilliantly; Stiles was too far gone to control his heart rate
and it wasn’t lying.
 
Derek attacked his mouth, kissing and practically fucking his mouth before he
pulled back, a string of saliva connecting them. Stiles blinked at him, dazed.
“I meant it.” Derek said before continuing to kiss Stiles. Derek pulled back to
kiss down Stiles’ body, pausing to torture his nipples. Stiles moaned and
clutched weakly at Derek’s shoulders.
 
Derek’s clawed hands grabbed his ass and pulled it up, making Stiles yelp.
Derek smiled before spreading the globes of the smaller man’s ass and teasing
the rim with the pad of his thumb. Stiles moan turned into a harsh yelp as
Derek ducked his head down and laved at the opening as his hands tweaked at
Stiles’ nipples.
 
“Derek.” Stiles whined as the older man’s tongue furiously fucked his hole. “I
need…I need…” he gasped brokenly as Derek pulled away. He moaned and reached
for his lover weakly as Derek rooted through his drawers for some lube. Stiles
groaned like a cheap whore as Derek’s cold fingers returned, sans claws, and he
pressed his first in. Derek slowly worked him open with one finger, then two,
then three, while kissing him lazily.
“Derek.” Stiles said, seriously and Derek pulled away to look at him in
confusion, wondering if Stiles wanted to stop. “No silly,” Stiles stroked his
cheek. “I want you…to knot me. Mate me.” He blushed at the words spilling from
his mouth. Derek moaned and kissed him furiously.
 
“Stiles…mating is…it’s not like marriage…you can’t get a divorce.”
 
“I know!” Stiles whined as Derek pressed on his sweet spot. “I want this. I
want you. Forever.” Derek nodded and withdrew his fingers to slick himself up.
Stiles whimpered at the loss of contact but it soon turned into a moan as the
head of Derek’s cock pressed at his entrance. Derek growled, low in his throat
as he pressed into the boy.
 
“After tonight...” He panted, eyes glowing. “Everyone will know. Everyone will
know you’re mine.” He growled, sucking kisses into the skin of Stile’s neck.
 
“Good.” Stiles moaned. “Don’t want anyone but you. ‘S why I broke up with—”
 
“Stiles if you say my cousins name during sex I will pull out right now and
leave you like this.” Derek threatened. Stiles giggled and kissed the corner of
his mouth.
 
“Got it. Now move.”
 
Derek did just that, sliding in and out smoothly. The only sounds in the
apartment were the lewd slapping of skin against skin and their harsh
breathing, punctured occasionally by Derek’s animalistic growls. “’M gonna knot
you Stiles.” Derek moaned. You’re going to love it. Going to come on my cock,
screaming as I fill you up to the brim. And then when I pull out, I’m going to
eat my come out of you.”
 
Stiles whimpered and nodded enthusiastically. “You’re doing so well.” Derek
moaned, licking at Stiles’ now thoroughly abused shoulder. “Feel so good for
me, baby.” Stiles whimpered and clawed at Derek’s back, bucking against him and
chasing after another orgasm. “So tight.” Derek moaned turning his attention to
Stiles’ other shoulder.
Stiles moaned as Derek started pounding into his prostate, again and again and
again. With one last, deep thrust Derek stilled in him and Stiles could feel
his knot growing. He moaned as the pressure increased and he felt more full
than he could have possibly imagined. Derek was moving in aborted little
thrusts that had both of them whimpering.
“Come for me Stiles.” Derek growled, eyes flashing and stiles shuddered his
release. Derek whined as Stiles clenched around him and he released into the
boy, whining and keening. He collapsed onto his forearms and kissed desperately
at Stiles lips before biting at his shoulder. They groaned as Derek continued
to release into him for long moments. Stiles felt so full and he shuddered as
Derek tongued at the claiming bite.
 
Derek maneuvered them into a more comfortable position, spooning Stiles and
pulling the blanket up over them.
 
“What happened to eating me out?” Stiles whispered. Derek smiled and took
Stiles hand in his, kissing his wrist.
 
“All in good time. All in good time.” He sighed before kissing the still
trembling boy’s forehead. Stiles closed his eyes and leaned into the kiss. “You
smell like mine.” Derek whispered.
 
“Yours.” Stiles agreed.
 
 
The only thing the Sheriff said the next day when he saw them was, “Guess he
wasn’t blackmailing you.”
