Authors Note: I know it's been forever since I updated this. I apologize. School, work and life in general has been incredibly hectic and I don't have much spare time anymore. However, that being said, I will NEVER abandon this fic. It might take me a while to complete it since there is still a lot of this story to be told, but I will never leave a story abandoned. Also, I have started to write a few other sterek fics. They aren't posted or anything because I want to be finished (or nearly finished) with them before posting, so keep a look out for those in the future. One last thing: since I don't have much time on my hands, chapters may be a lot shorter than what they have previously been.

Lastly, smut. That is all.

XOXOXOXO

Derek found himself sitting in the break room on Wednesday, heating up a square of lasagna in the microwave that he had brought from home. His mouth flooded with saliva at the smell of bubbling cheese wafting throughout the room. He heard the faint clacking of high heels on the linoleum floor, alerting him to Lydia's presence a full 20 seconds before she appeared in the doorway.

Her red hair was done up in a professional bun, her usual work uniform traded in for a black pencil skirt and a white button-up top. She gave Derek a head nod as she entered the room, walking swiftly over to the coffee machine.

"I have a new assignment for you, Hale."

Derek resisted the urge to groan. This would be the sixth "new assignment" she'd given him since Monday.

The microwave beeped loudly, prompting Derek to scoop the plate of lasagna out and onto the small table. "Details?"

The coffee pot started crackling as it began spewing new coffee. Lydia took the time to sit down across from Derek and give him her critical eye, the one that left Derek feeling like a small, vulnerable child. Derek loathed that look.

"It was reported that Chris Argent returned to Beacon Hills yesterday. We've been keeping an eye on his house for the past twenty-four hours, and we'll continue to do so until someone interrogates him."

"You want me to interrogate him?" Derek asked, shoveling a warm forkful of food into his mouth.

"Obviously," Lydia drawled, rolling her eyes. "You're my best worker. You get straight to the point and don't fuck around. You're the only one I trust with this case being the entire 'Argent debacle' is the biggest thing to have happened in years."

Derek pushed his food around with his fork for a moment before giving a light sigh. "All right. I'll do it."

"Great," Lydia smirked. "I'll have the file on your desk in the next hour." She got up to grab a mug from the cupboard, but she continued speaking. "The basic information you need to know is that Chris Argent has been away on 'vacation' for the past few months. Everybody is obviously suspicious about him being a part of what went on with Gerard and Kate, so that's what we need to find out. If he was, then he goes to jail. End of story. If not, well, I highly doubt he's innocent, but if he is, then we let it go."

"Right, gotcha," Derek mumbled, scraping the last of the lasagna onto his fork. "I'll handle it."

"I never thought you couldn't," Lydia replied, a hint of smugness in her voice. She poured herself some coffee and rejoined Derek at the table. "So, got any plans with your sweetie tonight?"

Derek fought off the smile that threatened to break out on his face. He couldn't help it. The thought of Stiles gave him a severe case of tummy butterflies. "Yes, actually. We're going to have dinner with our neighbors. He's still very wary around most people, but he really likes Jackson and Danny."

Lydia arched a fine eyebrow at him before squinting her eyes. "Jackson and Danny? As in, Whittemore and Mahealani?"

"Yes," Derek said, surprised. "You know them?"

"Actually, I dated Jackson for about two months in high school."

"Really?"

"Yup." Lydia took a moment to sip at her coffee. "That is, until we figured out he was gay."

Derek snorted. "Oh, he's gay all right."

Lydia hummed in agreement, adding, "So then he was basically my sassy gay friend. I was actually the one who got him and Danny together. It was a blind date. Danny was a friend of my family, older than us high school kids. Next thing I knew, their blind date turned into a serious thing when Jackson recognized Danny as his alpha. Christ, they practically fucked right there on the floor of the restaurant."

Derek had been sipping on milk as she was talking, but it practically came out of his nose at her graphic description. Not that he was against sex, but he didn't want to imagine his neighbors grinding against each other with no clothes on. Though, Jackson had to have become pregnant somehow...

"Then I was invited to their wedding," Lydia continued. "Of course, I had planned the entire damn thing, so it would have been rude of them not to. Then over the years we just kind of lost touch. Are they still all lovey dovey like they used to be?"

Derek chuckled. "And then some. Jackson's actually pregnant. I guarantee his hormones are going crazy."

Lydia gave him a 100% genuine smile, shocking Derek a little.

"That's great," she squealed, her face going serious once more. "That bastard better name it after me if it's a girl. He promised me he would a long time ago."

Derek just sat there and laughed, seeing the smile Lydia was trying to keep off her lips. She failed miserably.

XOXOXOXO

"You want a beer?" Danny asked, standing in front of his open fridge.

"Hell yes," Derek responded, setting a bowl of homemade mashed potatoes onto the counter. It was his moms recipe, and it was to die for. Danny was barbecuing chicken, so Derek had brought over the dish as a side.

"Rough day at work?" Danny asked, raising an eyebrow as he grabbed a bottle of beer and tossed it to Derek.

Derek cracked it open and took a long swig, wiping his mouth before saying, "You could say that."

Danny just grinned and cracked open his own. There were a few beats of comfortable silence between them before Danny spoke up. "So, did you get any further with trying to find Stiles' dad?"

Derek sighed and shook his head no. "Afraid not. I'm at a dead end. But thanks for all the help. You don't even know how much that information put some of my mind at ease."

"Anytime," Danny grinned, looking towards the hallway when the sound of laughter came from one of the bedrooms.

Derek chuckled. "They're giggling over baby magazines."

"Of course," Danny replied. "I swear, Jackson has bought every single baby magazine within a ten mile radius."

"Don't lie. You love it," Derek teased.

Danny held up his hands in surrender, grinning. "I confess. It's just... Jackson is usually so serious and uptight. It's just a nice change to see him be a little... softer."

"He'll make a great dad," Derek replied, taking the lid off the steaming mashed potatoes. "And so will you."

"God, I hope so," Danny mumbled, grabbing a spatula to go and flip the chicken with. "At first when we found out he was pregnant, I was honestly terrified. The thought of taking care of another little, living person made me panic. I mean, I hardly remember where I put my damn phone every day. How the hell am I supposed to keep track of a baby?" Then, Danny's eyes grew warmer, a soft smile slipping onto his lips. "But then I thought about how we made it. I thought about how it's a little part of me and Jackson, all wrapped up in one tiny person, and then I realized how much I actually wanted a baby."

Derek smiled gently at his friend, now knowing for a fact that Danny would make a great father.

"Anyway," Danny continued, waving the spatula in the air. "The chicken's done. Do you mind telling them?"

"No problem." Derek walked towards the muffled talking as Danny walked onto his patio. Derek followed the noise to Danny's office, stopping in the doorway and looking at the two omegas.

Jackson was holding up some color swatches against the wall, and Stiles was staring at them intently, head cocked.

"Well, if it's a girl, I think the light pink would look better than dark pink," Stiles said, oblivious to Derek's presence.

"Thank god," Jackson sighed, setting the swatches onto Danny's desk. "I knew that was the perfect color."

"Hey, you two," Derek spoke up, making Stiles jump and cower a little. Derek immediately walked over to Stiles and wrapped his arms around Stiles' waist, pulling him to his chest. "Dinner's ready."

Jackson did a fist-bump in the air. "Yes! We're starving." He looked down at his belly and gave it a light pat. "Aren't we, sweetie?" He then proceeded to walk out the door.

"Sorry, I didn't mean to frighten you," Derek whispered into Stiles' hairline.

The light press of Stiles' lips against his was the response he got. He cupped the back of the omega's head, lacing his fingers through the silky hair as he deepened the kiss, making it soft and warm.

Stiles pulled away, a blush forming on his cheeks. "It's ok." He batted his lashes at the alpha. "Make it up to me later?"

Derek just blinked at him for a moment, dumbfounded. Then he grinned.

"Did you just hit on me?" Derek asked, rubbing the tips of their noses together.

Stiles blushed a deep red, but wound his arms around Derek's neck anyway, pecking him lightly on the lips. "Maybe."

Derek chuckled and gave Stiles' bottom a light spank, whispering in his ear, "You naughty little thing."

The soft, light moan that escaped Stiles mouth surprised Derek. It also made him go hot with arousal, which wasn't exactly ideal when a person was going to sit down to dinner with a group of friends.

"We'll finish this later," Derek murmured. "I promise."

"Good," Stiles replied, pupils almost dilated. Fuck, Derek wanted to touch him right then and there. Just wanted to hold Stiles against his body while he shoved a hand down the omegas sweatpants and curled his fingers up into the hot, wet love-den.

Derek shook his head a little to snap out of his thoughts. He didn't need Jackson making fun of him. Quickly, Derek bent down and scooped Stiles up, earning a squeal of delight from his mate. "Up we go," Derek supplied, walking the two of them down the hall and to the kitchen.

The four of them sat down and ate, the sound of friendly chatter and clinking silver wear filling the air. Despite not being much of a people person, Derek genuinely enjoyed being in the company of Danny and Jackson. He had gotten to know them well in the past month. They both proved to be good friends to Derek and Stiles. Derek hadn't had a best friend since high school, but if he had to sum up his and Danny's relationship, it would have the label of 'best friends.' He was about 99% sure the feeling was mutual. They just had too much in common not to be.

Once dinner was over, Derek and Stiles helped clean up the dishes. They both listened to Danny and Jackson playfully bicker back and forth with each other for a solid 10 minutes before Derek understood that that was their form of foreplay. Once he was hit with that realization, Derek hastily excused himself and Stiles from their house. Jackson sent him a devilish smirk before Derek could fully close the door. He shuddered as he pulled Stiles over to their own house. There were just some things Derek did not want to see, know matter how fond he was of his friends.

Derek threaded his and Stiles' fingers together as he opened their door, ushering Stiles inside first before following. As soon as Derek closed the door, he quickly turned around and pulled Stiles to him, hands grasping beneath the omegas thighs as he hoisted him up, allowing Stiles to wrap his legs around Derek's waist. Stiles smiled bashfully as he curled his fingers into the cloth at the shoulders of Derek's shirt.

"What do you want, little one?" Derek asked in a low voice, his nose nudging Stiles' cheek.

Stiles blinked at him with his gorgeous eyes before responding shyly. "I want a kiss."

Derek grinned, rubbing their noses together. "Your wish is my command."

He sealed his lips over Stiles', the gentle pressure making butterflies flutter in his stomach. His nose was assaulted with the overwhelming smell of happiness and lust, making his wolf want to wag it's tail proudly. To know that he could invoke such responses from the little sweetheart in his arms was enough to make his head spin with joy.

Their kisses turned from light and happy to deep and passionate in less than a minute. Derek let his tongue explore Stiles' mouth while the omega wound his arms around Derek's neck.

The alpha didn't even realize he was walking until his legs hit the couch. He made a surprised noise before placing Stiles onto the soft cushions, detaching their mouths for a moment while he got them situated. He placed Stiles sideways so he was lying down, taking the chance to crawl over the smaller boy, settling himself between Stiles' legs. Stiles' eyes shone with raw want as he licked his spit-shiny lips, causing a low growl to escape Derek's throat.

Derek dove in once more, licking his way into Stiles' sweet mouth. His hands settled low on Stiles' hips as the omega gripped the front of Derek's shirt between his fingers, whining. Derek let out a soothing noise in response, his fingers trailing adventurously beneath Stiles' shirt, fingers ghosting along warm skin.

Suddenly, Stiles broke the kiss and wrinkled his nose in distaste. Derek froze his movements and pulled back a fraction, looking worriedly at the smaller boy.

"Stiles?" he questioned, eyes flickering over Stiles' face. "What's wrong? We can stop if you want."

Stiles gave a small shake of his head, his cheeks heating up before whispering, "It's really wet down there."

Derek let out a small, relieved chuckle and pressed a deep kiss to Stiles' lips. "That's completely normal, babe. It's because you're turned on. Your body's just trying to prepare you for sex. And even though we're not having sex, it's slicking you up just in case. That will happen every time you're turned on."

Of course Stiles' wouldn't have known any of that. Other than that one time a few weeks ago, they hadn't done anything more than kiss and cuddle. Fuck, Derek loved to cuddle.

"Oh," Stiles replied, his blush deepening.

A few seconds of silence went by before Derek swallowed hard, asking throatily, "Can I see?"

Stiles just blinked at him for a few moments, his heart ticking a little faster. Only it wasn't out of fear. It was nervousness combined with excitement, judging by the spike in his scent. Slowly he nodded yes, his tongue flickering out to wet his lips.

Derek smiled softly and leaned forward, pressing a soft kiss to the sweet mouth and taking his time to lick his way inside. His fingers hooked gently beneath the elastic of Stiles' sweatpants and boxers, very slowly pulling them down the slim hips, revealing inch after inch of creamy skin. Stiles obediently lifted his legs so Derek could easily slide them off. Once he flung them to the side, he broke their kiss, nuzzling Stiles' cheek affectionately.

"You sure?" Derek asked, hands gently rubbing up and down the bare thighs.

Stiles smiled and batted his eyelashes shyly. "Yeah." That said, he relaxed back into the cushions and stared up at Derek with half lidded eyes.

Derek nodded and slowly leaned back onto his heels, fingers trailing along the exposed skin on the journey down. Derek watched as goosebumps raised on Stiles' flesh along the path that his fingers traveled, making the alpha chuckle. As his hands got lower, he carefully pushed Stiles' thighs up and apart, spreading the omegas legs so he had the perfect view of the small, very slick hole. Derek's mouth immediately watered. Not only the sight was delicious, but the smell was heavenly. It was the most potent area on an omega when it came to their scent, and it was doing it's job well if Derek's flickering red eyes were anything to go by. He had the biggest urge to just lean forward and bury his face between the perfect little cheeks and make a thorough meal out of Stiles...

...So he did.

He held eye contact with Stiles as he leaned forward and licked a long, slow stripe over Stiles' quivering hole. Derek held back a satisfied growl as he watched the omegas pretty eyes dilate and his mouth fall open in a small 'o'. A fine blush made it's way onto Stiles' cheeks, making him look down right scrumptious. His hands found their way to the collar of Derek's shirt, fisting the material in his hands.

"That feel nice, little one?" Derek asked, voice low and throaty. He softly nuzzled Stiles' inner thigh, making Stiles' eyelashes flutter rapidly.

"Uh-huh," Stiles breathed, wetting his lips with his tongue.

Derek chuckled, sucking a bruising kiss onto the pale flesh next to Stiles' butt cheek. The breathy whine that Stiles let out was music to Derek's ears, and it encouraged him to keep going. Derek moved his mouth back to Stiles' hole and lapped at it some more, alternating between small flicks of his tongue and long, deep licks. He let out a satisfied growl as more of Stiles' slick trickled out, accompanied by a high whine from Stiles' mouth, his small fingers tightening further in Derek's shirt.

Derek grinned playfully at his mate before flexing his tongue, licking inside of Stiles as far as he could. That drove Stiles crazy, causing him to buck his hips a little, trying to get more of Derek's tongue inside of him.

"Like that?" Derek chuckled when he pulled away, tongue swiping across his own lips to gather up the extra slick.

"Yeah," Stiles breathed, a beautiful flush spread across his cheeks. His lips looked raw from kissing, and his eyes were heavily hooded.

Derek just grinned before diving back in, holding Stiles' thighs apart as he pushed his tongue inside him once again, curling and twisting it to the best of his ability. It was when Derek let out a small growl that Stiles came, no doubt the vibrations from the growl giving Stiles pleasure.

Stiles let out a tiny mewl and threw his head back, eyes closed, looking absolutely delicious to Derek in his obvious ecstasy. Along with the small spurt of come that Stiles released, a fresh wave of slick came gushing out as well, dripping down Derek's chin and coating the backs of Stiles' thighs.

Derek rumbled in satisfaction as he licked his mate clean, trying to stay away from any sensitive areas that may be overstimulated. As he continued his work, he looked up through his eyelashes at Stiles, whose chest was rising and falling rapidly as he tried catching his breath. His head was lolled onto it's left side and his eyes were half-lidded., a small smile on his lips.

Derek lifted his head from where he was cleaning Stiles, wiping his mouth with his sleeve and grinning wolfishly.

"How'd that feel?"

Stiles let out a bubble of laughter, his eyes shining. "Good. I didn't know anything could feel that good."

A spark of anger flared in Derek's chest at the words. He wasn't mad at Stiles. He was mad at the fact that those bastards who had held him captive could ingrain so much pain into Stiles' mind and body that the little omega didn't even know anything could feel nice. Well, for as long as Derek was alive, he would show Stiles how good it could be.

"Well you better believe it, baby, because I'm going to make you feel as good as I possibly can for the rest of our lives."

Stiles giggled again before giving his body a small stretch, a yawn escaping his mouth. "I'm tired."

Derek chuckled and stood up, bending down once more to scoop Stiles up into his arms. He placed a lingering kiss onto the omeags cheek as he carried him towards their bedroom.

"Thats' perfectly normal," Derek said. "Having an orgasm contracts a lot of muscles in your body and really gets your heart pumping. Being tired after sex is something that happens to many people. It's probably got an even larger effect on you considering your body is still trying to heal."

"Oh," Stiles responded, blushing cutely as he shyly buried his face into Derek's neck.

"You want a bath, little one?" Derek asked, nuzzling Stiles' soft hair.

"Yeah," came the muffled response. "I'm kinda sweaty and sticky."

"Bath it is then," Derek grinned. "We can take one together, if you'd like."

Stiles pulled his face away from Derek neck to look at him through his lashes. "I'd love that."

"Your wish is my command," Derek responded, heading towards the bathroom, grinning the entire way.

XOXOXOXO

Early the next morning, Derek found himself sitting on a lumpy couch in Chris Argent's home, said man sitting across from him in a rocking chair. He didn't look anything like the pictures Derek had seen of him. In the pictures he looked young and sharp as a whip. In person, well, he looked old. He had a scraggly beard, streaks of grey shimmering within it. There were noticeable bags beneath his eyes, making him look very tired and worn, like he had had just about enough of the world. Despite the fact that Derek was there to interrogate him, he couldn't help but feel sorry for Chris.

"Sorry if you don't like the tea," Chris spoke up in a hoarse voice, taking a sip from his own cup. "It's all I have at the moment."

"Oh, it's perfectly fine," Derek replied, quickly taking a sip of his own and holding back a grimace at the revolting taste. He set the cup back down and sighed gently. "So, Mr. Argent. You know why I'm here. The sooner we get this over with, the quicker we can both get on with our day."

Chris just silently set his cup down and looked at Derek with a glazed expression. "I didn't take any part in what my father and sister did. None of it." Chris' mouth twisted into a bone-chilling smile. "No, father said I was never smart enough to take part in anything like that."

Derek held back a shiver at Chris' blank gaze, but took note that he wasn't lying.

"Well, I'd say you were smart to not get involved with your fathers doings."

"Yeah," Chris mumbled, now looking past Derek completely, lost in his own mind. "Smart." His hand seemed to automatically go to a picture on the coffee table, tracing his finger over the edge over and over again.

Squinting, Derek could see it was a picture of two women, one older with red hair while the other looked to be a teenager with long, black hair and pale skin. They were looking at the camera and smiling, arms around each other in a hug.

"Family of yours?" Derek asked softly, thinking rough tactics would not work with Chris. He didn't seem to be playing with a full deck. He needed to be careful with the words he chose.

"Yeah," Chris mumbled, still staring blankly into thin air, but he turned the photo a little so Derek could have a better look.

"Is the red-head your wife?" Derek asked, pointing to her.

"Was," Chris replied, no emotion showing on his face. "She's dead. Car accident a few years ago."

"I'm sorry to hear that," Derek apologized sincerely. "Is the other one your daughter?"

At this question, Derek noticed Chris' heart beat painfully in his chest, his face showing signs of grief.

"Yeah," he answered. "Allison. She went missing a while back. Authorities could never find her."

Derek's heart tugged painfully in his chest. He suddenly felt very sorry for this poor man. "I'm very sorry for all of your loss. For all of your losses."

That comment made Chris' face contort into a look of anger, a malicious smile taking over his lips. "You can be sorry for Victoria and Allison, but I don't give a shit about my dad and sister. They were bad people. Always were. Always looking to manipulate everybody. Kate used to be good, you know. She used to be the perfect little angel. But my dad-no, Gerard-twisted his way into her head, just like he twists his way into everybody's. He would have tried getting to Allison next if she hadn't gone missing." Chris then let out a humorless chuckle. "Did you know that that bastard didn't even try to help find her? Ok, he did the bare minimum and contacted authorities, but besides that he never batted an eyelash." A deep sadness then took over Chris' face, giving him that world-weary look once more. "I think about her every day. I like to think that she's still alive out there. You can't give up hope as a parent, you know? I like to think that one day she'll be found, and that she can come back and live with me again. But with each day that passes, I get more and more hopeless."

Derek smiled sadly at Chris before he slowly stood up. Chris looked up at him,

"I'm very sorry for disrupting your day," Derek apologized. "You're free to do as you please. You were obviously not part of what your father and sister did, so I'm sorry for interrogating you."

Chris just shrugged. "It's your job. No need to apologize."

"Once again, I'm sorry about your wife and daughter. I can't even imagine how horrible something like that is. I'll just show myself out, but have a good day Mr. Argent."

Chris just gave a brief nod of his head in reply before sipping at his tea, allowing Derek to slip down the hallway towards the front door. The hallway came to an end in the tiny kitchen, the front door right next to the fridge. As Derek reached for the knob, a picture on Chris' white fridge caught his attention. It was a picture of Chris' daughter again, but it was more up close than the other one. You could clearly see the dimples on her cheeks when she smiled, the pretty brown color of her eyes, the sun reflecting off her pearly white teeth. She looked happy, healthy and carefree.

But... something was off. Not with the picture or Allison herself, but something was weird about the feeling it gave Derek. It was like she looked familiar to him, but he had never seen her a day in his life. He just couldn't put his finger on it.

With a troubled mind, Derek opened the door and left, trying to put thoughts of Chris and Allison out of his mind.

XOXOXOXO

Derek had his laptop settled on the top of his thighs, the fabric of his blanket separating skin from steele. He was reclined against the headboard of his bed, Stiles curled into his side and softly drooling on his chest. The omega was naked beneath the sheet due to certain activities taking place not but 10 minutes before.

Derek just smiled affectionately down at the sleeping face, pressing a kiss to the messy hair. "I wore you out, didn't I?" he said, chuckling softly.

Turning his attention back to the laptop screen, he sighed, eyes scanning the google page. He had typed in 'Allison Argent,' and only a few articles had popped up. They all claimed the same thing, that she had just simply went missing one day nearly a year ago and was never found.

He clicked on the article at the very top of the page, leading him to a news website. A photo of Allison was at the top, different from the two pictures he'd seen in Chris' house. This one was her school picture, showing her in a red shirt smiling sweetly at the camera.

Derek frowned in concentration, feeling the same sense of deja vu that he had had at Chris Argent's house. It annoyed him that he couldn't remember why he was having such a reaction to her picture. Perhaps he had seen her around town before she had gone missing? That couldn't have been it, though. He had seen plenty of people wandering around the streets of Beacon Hills. He surely wouldn't be able to pick out any of them in a crowd.

Derek then thought that maybe he had seen pictures of her when she had gone missing, which would explain why he recognized her. But he couldn't remember ever seeing files on her case, so he ruled that option out as well.

Derek sighed in frustration and closed his laptop, his eyes glancing one last time at Allison's picture. If he kept trying to figure it out, he would just get even more frustrated. He needed a break from it for a while. Maybe when he tried again with a clear head, he'd be able to remember details. Then again, maybe he had never seen her anywhere before and his brain was just tricking him. Either way, he would try again after a good nights sleep.

Derek reached over and clicked off the lamp, bathing the room in darkness, save for the moonbeams spilling in through the window. He shuffled down a little so he could rest his head on his pillow, trying not to jostle the sleeping omega in his arms. Stiles' eyelids fluttered for a few minutes, unfocused eyes looking blearily around the room. Derek stroked his back and made soothing sounds in response, allowing the omega to snuggle closer and fall back asleep.

Derek laughed lightly, kissing the messy hair once more. He shut his eyes himself as he wrapped his arms around his mate, chest rumbling in satisfaction. The stress in every one of his muscles started to fade away as he breathed in the sweet, light scent of pure Stiles. It soothed every ache in him like nothing else in the world could.

It was just as he was starting to finally doze off when it hit him, his eyes snapping wide open.

Allison Argent.

He had seen her before.

He had seen her in Eichen House.
