A/N:

About six months ago I fell in love with this ship, I was a fan of the show already and just saw some Au's on Instagram and now I'm obsessed, Like really obsessed! I read about 30 fanfics and counting. LOL

I woke up from this dream I had about Sterek and then I started to write this fic.

I have never written any fanfic in my entire life so be kind to me.

Since it's an AU and a lot of people is alive, the characters' behavior is kinda different.

############### THIS MEANS POV CHANGING.

"Italic text in the story." And this means a thought from a character, whether or not I say specifically in the story.

I hope you like, and let me know! xoxo

*As requested, warning! There's some Stalia before Sterek can happen!

Also explicit sexual content (M/M) and mentions of knotting.*


Derek just sat there on the edge of his college dorm bed, looking at nowhere, waiting "I'm not ready for this." He thought. You would think that after seven years of intense training with his mother that he would be. But how he was going to take care of a pack if he didn't even know what he was doing with his own life? Because really, what has he done to show that he was worth it? Well, he did let his first girlfriend die, which it was his fault by the way, not long after that, he fell in love (again) with a psychopath that murdered several members of his family, including his dad. Said psychopath, had asked Derek to mate her, so they could be together forever. "I'm not ready yet." He had answered her. She wasn't happy about it, in fact, she got really mad at him, saying. "You lied to me, Derek! If you're not ready then I'm not your mate at all!" But Derek hadn't lied to her. Later on, he figured out it was just blind passion and a stupid mistake of not hearing his wolf properly. And that mistake had cost his family.

On top of that, his mother was constantly telling him that he needed a mate and should stop fooling around with a bunch of strangers to focused on finding a mate. Just one more motive for his mother disappointment at him. But Derek just really did NOT want a mate, like ever! Okay, that wasn't entirely true, but he really didn't want to fall in love again just to end up badly one more time, just couldn't do it anymore.

So yeah, he was not worth it at all, even his mother knew that. But OOH the universe had chosen him! Well, the universe was wrong this time! Laura should have been born with this tattoo not him, she should have been born a werewolf not him. Derek sighed, hearing his best friend entering the room.

"Are you ready?" Isaac said touching his shoulders.

"No." He answered his best friend.

"Yeah, me neither, come on let's go." Yeah, there was that too, he had to choose someone to be his second in command. Great, another thing to add to his guilt party list. Well, there was nothing Derek could do about all of that in that moment, if ever. So he got up, got his belongings and followed his best friend out from the college dorm.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

When Derek got home, his mother was waiting for him on the front porch with a beaming smile. He could not resist and smiled back at her. God, he loves her so much! He walked towards her, dropped his baggage and gave her a hug.

"I missed you, honey!" Derek's mother said, crushing him tightly. "Come, everyone is here to see you, both of you" She looked at Isaac who was beside Derek, waiting for his turn with their Alpha too. She hugged Isaac as well and motioned for them to enter the house.

Derek got into the living room and saw Peter sitting at the edge of the couch, resting his head on the backrest, Malia lying down on her father's thigh, legs on Erica's lap. Cora beside Erica, Boyd on the floor between Erica's legs. Laura sitting on the other couch beside Deaton's daughter, Breaden. Deaton by the fireplace and Claudia sitting in the armchair beside him. Everybody talking to each other happily. "The Sheriff and Melissa probably are still at work." He thought. Looking at the scene it felt good but at the same time, felt like it was missing something. Not being able to pinpoint what, he pushed it aside.

Erica got up to her feet the minute Isaac stepped into the room and was throwing herself at her brother. If he wasn't a werewolf they would be on the floor. Derek shook his head smiling, he missed his pack and for a moment was able to forget about all his responsibilities. She stretched an arm and grabbed him too for the hug. As he hugged her back, everybody got up and came for a big pack hug bonding. "Yeah, feels good to be home." He thought.

"I missed you guys!" He said, into the group hug. Everybody was saying they missed them too.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

They all had dinner at the Hale house, talking about what each one of them did that year, and what they gonna do this summer. Cora and Erica went on and on about the trip they were going to do next week, Boyd and Isaac were talking by his side, Laura was talking about her job at SID (Supernatural Investigation Division) with Breaden-they both worked there- and his mother was talking with Claudia and Deaton. Derek didn't attend one of those dinners for over six months, last year of college was hard.

After dinner was over and everyone -who didn't live at the Hale house- was gone. Derek took a bath and went to his room closing the door, he was really tired. A knock came to his door and his mother entered his room.

"Derek," Talia called him. He looked at her listening. "How is the search for your mate?" Derek rolled his eyes at that.

"Mom, I told you, I'm not getting a mate." He bluntly told her, looking seriously at his mother.

"Derek," She sighed. "You can't do this, you need a mate! You will be an alpha Derek, you have a pack to take care of"

"Mom not every werewolf has a mate, even alphas." He closed his arms across his chest.

"Son, how many times I have to tell you, Claudia saw you with a mate on her vision!? And since we don't know who it is, you have to look for them!" She raised her voice a little, irritated by her son.

"You said so yourself on our training, not every premonition is accurate." Derek said, also irritated. It's not like he didn't think about it, or wanted if he was really honest with himself. But he just couldn't do it, period. He sighed and said, tired. "Can we not talk about this right now? I just got home mom."

She scratched her forehead, "Okay, you're right, I'm sorry. Good night honey, I love you." With that, she exited his room closing the door

He woke up early the next morning and went to a run at the preserve after breakfast, while running, decided to go for swimming at the lake, -it was really hot that day- getting by the lake Derek heard voices. "Great, the kids are here." He thought, almost giving up and getting back, but there was a smell, he was drawn to it. The scent was so good that Derek just kept going without even thinking. By the lake he saw, Melissa's son, "Scott ." he remembered, "The boy who was bitten by my mother when he was little and almost dying. " a brunette girl with Scott at the lakeshore, two other boys he didn't know and a redhead at the water. Looking at the scene he saw, another boy running towards the water. "Claudia's son but wow! Was he, really?" The boy looked beautiful, his smile was gorgeous, pale chest with moles all over, flat stomach showing. The boy was smiling at his friends and running to jump in the water. Derek stopped, thinking. "Where's the smell coming from?" Not wanting to go any closer to risk Scott hearing him. He shook his head out of the thought, and the boy. Turned around and jogged back home.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

"Hey man!" Isaac said with his mouth full of cereals as Derek entered the back door into the kitchen.

"Morning." He said opening the fridge to get some water.

"I was thinking, we should go swimming, is so hot today."

"Nope, the kids are there, Claudia and Melissa's sons and their friends." Derek said sitting by his best friend at the kitchen table.

"So? They're pack, you should get to know them better. Besides, they're not that younger than us you know." Isaac said with one eyebrow raised.

"No Isaac, I'm not in the mood!" He answered, got up and out of the kitchen.

"God, what happened?" His friend asked following him to the living room where Derek sat in the armchair and Isaac on the couch beside him.

"I just don't wanna be with a bunch of teenagers" He answered -not lying exactly because he really didn't wanna be with a bunch of teenagers- without looking at his friend. "God, what's my problem? It was just a smell! I shouldn't be irritated like this. I don't even know where was coming from." Derek's mind went to the boy again. "Was the smell coming from him? No, nope, don't go there Derek. Just stop thinking about this."

Stiles entered his house calling for his mother, she called back from the kitchen where she was by the stove, making dinner when she turned around to look at him.

"How was the lake?" She asked.

"The water was very refreshing, we did a jump competition, which Scott win, of course, damn his wolf powers. We did a little hiking, not my greatest moments by the way but I managed without any breaking bones." He stopped noticing he was rambling a little. "Yeah, it was good, what's for dinner?"

"I'm making lasagna. Where were you yesterday, when Derek came home?" His mother asked.

"You know, helping Scott get rid of his fleas, poor guy was very itchy." His mother scolded him with her eyes.

Stiles rolled his eyes at her and said. "Mom, he doesn't like me, why would I be there?"

"Sweetheart, I already told you that's not true. Derek just had a lot on his mind for those past seven years, after his father died. And he's our future alpha. You should have been there, and Scott too. I know that was your doing!" She pointed a finger at him.

"Dad didn't go too" He pouted.

"Stiles, your dad was working you know that, so was Melissa!" She turned back at the lasagna.

"Fine! I'm going next time." He said, walking towards the stairs to take a shower.

"Good. Next Sunday, dinner time with the pack as always." Claudia smiled.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

Starving, after taking a shower and put on some clothes, Stiles went to the kitchen again, to wait for dinner.

"Want some help?" He asked his mother.

"I'm almost done, but you can set the table, your dad is coming home any minute."

"Okay!" He said happily

His mother was a great cook and the lasagna was delicious like always, so Stiles ate too much and decided to watch a movie downstairs with his parents for a while before getting back to his room.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

"Oh my God Scott, you gonna give me a heart attack someday!" Stiles jumped and screamed when Scott climbed the window into his room as he opened the door.

Scott rolled his eyes at him saying. "I told you I was coming here after I dropped Allison at her house." With that, his friend sat at the edge of the bed by the window.

"Right. So, my mom asked me why we weren't there for dinner yesterday, at the Hale house, and we have to go next time."

"I told you she wouldn't like it."

"Yeah, well, I didn't wanna go! What's the point anyway? I'm human, not really pack material." He sighed, thinking. "Why am I not a witch like my mother? "

"Stiles, you are pack and you know it! I think you and me know why you didn't really wanna go." Scott said with a questioning look, like saying was about time they talk about it.

"I don't know what you're talking about" Stiles crossed his arms over his chest looking at his bestie with a frown.

"Yeah, you do! Before Derek started training with his mother and stopped talking to us, and more importantly giving you attention, we were always there with your mother and Talia." Scott looked at his friend expectantly.

Stiles sighed, looking at the ceiling. "I don't even know why this bothers me so much." He thought. "I got over it already Scott, we were kids and he was a teenager. It's fine really, I don't care anymore." He said throwing his arm down.

"Fine, let's play some video games then. That is why I came!" Scott smiled sitting on the floor and grabbing a controller.

"You came so I can kick your little Wolfie ass!" He laughed sitting beside his bestie.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

The week passed really fast, too fast for Stiles' liking, really. He had gone to the lake with friends, movie, a sleepover with Scott and bowling. Which Jackson kept insulting his skills, "Or lack of it." all night, and bragging about his, Scott making out with Allison, Lydia talking with Danny about fashion and him, being insulted. "It was a great night." He thought sarcastically, with himself. But that wasn't the worst that happened that week, no. The worst was when he saw Derek at the mall, he said hi and waved at the man and got absolutely no response, just a frown on Derek's face, as if Stiles hadn't showered for weeks. "What's up with that? I took a shower before getting out of the house!" He thought with a frown of his own, smelling himself discreetly. Then Derek shook his head waved back awkwardly and walked away. "Okay, what just happened?" So, tomorrow was Sunday and Stiles really didn't want to be, because he wouldn't be able to skip pack dinner this time.

########################

Derek was pacing in his bedroom, "This can't be happening!" thinking with himself. "No, no, really, it can't, what am I gonna do?" He stopped pacing and putting his hand on his face "Simple, I'm going to ignore it! Maybe it's not really what I think, maybe Stiles really smells good for everyone. Yeah, that's probably it! Because, why now? I know him since he was a little baby. Or maybe it was coincidence and the scent wasn't coming from him at all." A knock came on his open door, startling him, it was his mother.

"Derek, dinner is ready."

"Coming." He followed her to the kitchen table.

Isaac, Cora, Erica, Peter, and Malia were already at the table. His mother sat at the head of the table and he sat at the other. Peter beside his mother with Malia, Isaac beside him with Erica and Cora.

"We are going for our trip Monday, Derek. You should come." Cora said with a smile.

"I can't, I have to start working, but thanks."

"It's okay honey you can go and start next week." His mother said. Derek was going to work at her law firm.

"Come on Derek you had no fun for years, let's go with them, please!" Isaac said with puppy dog eyes, looking expectantly at Derek.

He thought a little in between bites, looked at his baby sister and said. "Where are you going?"

She smiled at him with hope in her eyes. "We're going to the beach, Laguna Beach, we have a house rented for the whole week!"

"Five days?!" He said, not really a question. "Okay, I guess I can wait for five days to start."

"Yes!" Came from Cora, Isaac and Erica, he smiled a little at them. "Maybe this is what I need to take that boy and smell out of my mind. Yeah, that will be good."

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

It was Sunday and some of the pack were already at the Hale house. So Derek was with the door opened sitting in the armchair in the office/library reading, when his nose caught that scent that was making him crazy for days in his mind. Derek was so caught up in the book that didn't even realize when he was out of the library and in the living room in a few seconds. When he got into the living room and saw Claudia, John and the boy, the latter closer to him by the four-seat couch greeting the rest of the pack, he froze. "Yeah, the scent is definitely him, fuck!" Claudia looked at Derek's panicked face, with a smug on her face, as if she knew what he was thinking.

He shook his head, faked a smile and went to greet his pack members, for his relief Stiles looked at him irritated and went to Scott's side on the floor on the other couch. He breathed out and went to the kitchen were Laura and Breaden were, making dinner. Every Sunday, two of the pack members cooked for the rest. Isaac was helping them, with almost the same expression of his own, when he discovered the scent was coming from Stiles. A wave of jealousy and possessiveness came crashing down on Derek, who didn't even realize his eyes were flashing blue and his teeth were showing until Isaac was touching him and saying.

"Derek, I'm freaking out! I need to talk to you, stop whatever this is and come with me!" His friend said grabbing his arm and pushing him towards his mom office, where they could talk freely since the office (and the bedrooms) were soundproofed. Derek shook his head again. "Damn it! What is my problem, I don't even want him anyway." He thought while following Isaac to the office, who closed the door looking at him panicked.

"Man, I think I just found my mate!" Isaac's voice was of horror and joy at the same time. Derek's eyes flashed blue again, he had to breathe and calm down not to rip his cousin's throat out right then and there.

Isaac looked at him with a confused look on his face. "What the hell is going on Derek? Why are you acting like this?"

"Who is it, Isaac?" He asked with a serious face and a frown.

"Scott." Derek relaxed immediately at that.

"Ooh, really? Are you sure? I mean, you know him for years, Isaac. Why now?" Though Derek didn't know if he was asking for himself or his cousin.

"Yeah, I'm sure! It's his smell, smells like mate. I can't really explain." His best friend smiled but his smile vanished right away. "He has a girlfriend, for years now! What am I gonna do?"

"I don't know, wait? Scott's a werewolf too, he probably knows already and will be coming for you, if not, talk to him."

"What if he doesn't want me because of her?" Isaac had that puppy look on his face.

"That's ridiculous he's a werewolf he can't resist the pull as well. Calm down, Isaac. we have a dinner to attend." Derek said, walking towards the office door when his friend stopped in front of him.

"Who is it, Derek?" Derek froze looking at his friend with fear in his eyes.

"Who is what?"

"You were all wolfie at me until I said Scott's name! You found your mate too, didn't you?" Isaac had a smug on his face.

"I'm not telling you anything! And besides I don't want a mate, it doesn't matter anyway." If Derek said he didn't find his mate, Isaac would know that he was lying, so why even bother.

"Keep lying to yourself." With that they got back to the kitchen -none of them wanting to get back to the living room- to help finish the dinner.

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

At the dinner table, Derek noticed, Isaac and Scott exchange shy looks, Stiles avoiding even looking at him, Claudia watching him and her son, smiling like she knew what was happening. Maybe she did. "She's a powerful witch." Derek couldn't shake the feeling he was getting towards the boy, feelings of need and want. To get to know Stiles better, make the boy like him. He didn't even realize he was staring at Stiles until the boy's brown eyes met his. Derek's heart jumped when the boy's eyes locked with his, started to beating so fast. Stiles' was with his face relaxed with the conversation of their pack members, but when he saw Derek's eyes on him, his face changed to a confused and surprised look. Stiles smiled a little on the corner of his mouth. It was beautiful and Derek couldn't look away, but a hand on his shoulders made him. It was Isaac, with a smirk. "Damn it!" He thought as his cousin took the hand out of his shoulder and said by his ear.

"It's Stiles isn't it?" So low that no one heard it (Hopefully). He nodded, not wanting to draw attention to them, and shoved more food into his mouth.

The rest of the dinner went fine. When everybody was finished, Talia told Cora, Erica, Scott, and Stiles to do the dishes since he and Isaac had helped to make the dinner. The elders went to the living room to talk and Malia to watch TV. Laura and Breaden went home because tomorrow they have to wake up early for work. Derek grabbed Isaac by the arm and went to the office again, while they were exiting the kitchen, he saw Scott looking at Isaac but not so shy anymore.

"What is it, Derek? Scott is in the kitchen I wanna be there with him, why don't you wanna be there with Stiles?" Isaac's face was both irritated and amused.

"Promise me you're not gonna tell anybody. Promise me, Isaac!" Derek's eyes flashed blue.

"Jesus, fine, can I get back now?" His cousin said, more irritated now.

"Thank you."

Isaac went back to the kitchen to help them and spend some time with Scott. Derek passed in front of the kitchen door, looking inside, Stiles was laughing, Cora with her teeth and claws showing, Erica between them but not doing anything to help. Derek entered the room fast and was at his baby sister in a heartbeat.

"CORA!" He said looking at her blue eyes with his, also blue.

"He started it!" She said with a frown, pointing at Stiles.

"I don't care, he's human!"

"Fine! I'm out, you can finish all of this alone Stiles." Cora looked at Stiles and then she was gone with Erica.

He sighed and turned around to the boy. "Here, let me help."

Stiles smiled and walked to Derek's side to help him wash the dishes, while Scott and Isaac dried. Derek smelled the happiness that was emanating from the boy and couldn't hold the smile of his own. "You have to stop this you can't do this, you can't have a mate." He thought to himself. But Stiles was so close to him that he just couldn't think straight. So he decided to leave as soon as possible, thus he finished the dishes as fast as he could.

"I'm going for a run." He said and left, smelling the boy sadness and confusion.

########################

Stiles was looking at the man before him, leaving at the back door, thinking that what he saw at the dinner table was his imagination. "Of course it was." Why would Derek look at him like that? He sighed and turned to his bestie, but he saw Scott talking in a low tone with Isaac, and there was a moment that their shoulders bumped a little. Someone less observant wouldn't have caught this, but this was Stiles. He frowned. "Was Scott flirting with Isaac?"

"Scotty buddy, are you two finished? Derek and I already did." Isaac was putting away the last plate.

"Yeah." Said Isaac and Scott at the same time.

Scott blushed a little. "Oh my God, Scott was flirting with Isaac!" Stiles looked at his friend with wide eyes.

"What?" His friend asked.

"What? Nothing! I'm just gonna go, chill in the living room, you know because I'm tired of all that cleaning and all." He said with his thumb pointed to the kitchen door. With that, he left as fast as he could without making it suspicious.

Getting at the living room his mother called him, she was sitting on the edge of the four-seat couch while Peter and Malia were at the other end of the said couch. His mother patted the couch beside her and he sat there.

"Where's Derek?" His mother asked.

"Went for a run." He answered with a heavy sighed.

"Hey, Stiles wanna play some game?" Said Malia beside him.

"Sure." Peter turned to look at him with blue beta eyes as a warning.

"Peter!" Talia said to her brother flashing her red eyes at him. "You have to stop this nonsense with your daughter, she has no friends because of you, and Stiles is pack!"

"Just ignore him!" Malia said rolling her eyes and pushing Stiles away from her crazy dad.

The rest of the evening was good, he played some board games with Malia, Isaac and Scott, and gave his number to Malia. Talia said she missed him and Scott and they should come more often, like when they were kids. Scott got happy with what his Alpha said and nodded happily. They parted ways with their parents and when Stiles was entering his father's car, he saw Derek coming from the woods and going inside the house. His heart jumped a little at the sight of the man and he could swear that Derek looked at him as his heart jumped.
