So a few people have said they would like to know about the day when Scott, Stiles and Jackson found out they were Mates, so this is a flashback chapter... After this chapter the story will continue as if this chapter never existed. ;)
~Flashback~
Jackson woke up rubbing his eyes. He groaned and stretched. He laid in his king sized bed looking up at the roof.
'Scott. Stiles.' Were the first things that ran through his head. He sat up and looked at the clock hanging on his wall.
"Still have an hour until I see them." He said to himself.
He froze getting out of bed.
"Why the hell am I thinking about them?!" He groaned.
There was a message on his phone from his parents wishing him a happy 18th, they moved to London last year, leaving the whole house to himself. He walked to the kitchen and made some breakfast. He rested his head on the wall behind him and sighed.
'I wonder what they feel like. I wonder if a Stiles would squirm if I ran my hand up his-'
"What the hell!" He cut himself off from his thoughts.
He ate in silence and tried not to think about the two annoying brats that he hates so much!
After he ate he got dressed leaving the house. He drove to Derek's, noticing everyone else's cars were already there.
His heart leaped when he notice the blue Jeep.
'Cut it out, Jackson!' He mentally yelled at himself.
He took a deep inhale through his nose, getting slapped with Scott's scent mixed with Stiles'.
Jackson moaned. He stomped up to the door and opened it.
"Happy birthday!" The pack yelled, running over to him to give him a hug.
He smiled until Scott and Stiles hugged him and he moved like he was just burnt. He looked to Derek who was smirking.
"Derek can I talk to you!" He panicked.
Derek raised an eye brow.
"Uh, sure."
They walked out the front door, walking a few metres into the woods.
"Whatever you have to say, does it have to be this far away from the house?" Derek raised an eyebrow again.
Jackson nodded.
"Yeah it does! Something is wrong with me!"
Derek nodded slowly, not understanding.
"Like what?" He asked.
"I keep thinking about..." He paused.
Derek was going to think he's gay or something.
"About...?" Derek asked.
Jackson tensed his jaw and groaned.
"About McCall and Stilinski. That's all I can smell, their scents mixed together and it's..." He paused again.
Derek smirked,
"It's comforting? Arousing?"
Jackson clenched his jaw again.
"Yeah, it is."
Derek put him hand on Jackson's shoulder.
"It means they're your true Mates. You know like your 'one and only', well, except you've got two. It happens when a wolf turns 18. I was like that with Isaac, he's all I could think about and smell. It's pretty powerful and overwhelming."
Jackson froze and his mind went blank.
"Mates?" He asked.
"Yep! You should go and tell them." Derek nodded.
"But- you're like 21, how did- how come it didn't hit you when you were 18?" Jackson asked.
"Because i didn't know Isaac when I was 18, and in some cases, it doesn't hit till both Mates are 18 or over. And that's just what happened to Isaac and I."
Jackson sighed and nodded. He walked back to the house and grabbed Scott and Stiles rather forcefully by the arms and dragged then into Derek's bedroom.
"What the hell is your problem!" Stiles snapped.
Jackson sighed and looked away. He was standing in front of the door so neither of his Mates could leave.
"I need to talk to you both." Jackson sighed, clenching his jaw.
"What is it?" Scott frowned.
"I-Derek said when a wolf turns 18, they find their Mate. He said the Mate's scent is the only thing they can smell."
"And?" Scott asked, getting slightly nervous but... Excited.
"And it turns out I have two. You two." Jackson smiled, getting pulled into a hug by Scott.
Stiles stepped back, feeling slightly sick. Scott, himself and Jackson, Mate?
'This is a joke. It's gotta be.' His thoughts were cut short when Scott pulled him into a hug aswell.
"And I want you both to move in with me today. I want to know you both are always going to be safe." Jackson said, kissing Stiles on the lips, then kissing Scott.
Scott moaned and Stiles stepped back.
"I-I need to talk to Derek and Peter for a sec." He said, clearing his throat.
Scott kissed him and Stiles smiled weakly, walking into the lounge room where the rest of the pack was.
Derek smiled at him. But frowned when he could tell Stiles wasn't very happy about the news.
"Derek, Peter, can I talk to you guys for a sec?"
They both nodded.
"Yeah, sure. Where's Scott and Jackson?" Derek asked, following Stiles onto the front veranda.
"Uh, making out in your room. But that's not the point. Jackson wants me as Scott to move in with him, but I don't want to." He whispered.
Derek and Peter both frowned.
"You have to." Peter said.
"Why do I 'have to'? Do I even get a say?"
"You have to move in with them. I'm sorry if they're moving too fast for you, but, that's just the way it is, Stiles." Peter said, patting his shoulder.
They remained silent until they heard cheering and a bunch of 'congratulations' in the house and Lydia was heard asking 'Where is Stiles?'
"Come on, time to go back inside." Derek nudged him.
Stiles frowned but nodded.
When he walked inside he was pulled into a hug by Scott and kissed in the cheek.
"We need to go to Scott's and Stiles' house and pack up all their stuff and take it to my house." Jackson said.
Stiles was about to protest but Peter shook his head and mouthed 'don't say anything.'
Stiles sighed and was about to walk out the door with the rest of the pack before he was pulled back. Finding himself wrapped in Jackson's arms. A slight purr was coming from the wolf.
"Alright, let's get all of your stuff over to my house." Jackson smiled, he was nervous, yet excited.
Stiles forced a smile to his lips.
"Yeah, I can't wait."
