Stiles laid in his bed for hours imagining all the ways Derek could kill him, then Cora woke up, looking at Stiles.
"You ok there?" She rubbed her eyes.
"No." He shook his head.
"What you thinking about?"
"Your brother."
"THAT'S what every girl wants to hear her boyfriend say in the morning after sex."
"Sorry." Stiles apologized still looking up at the ceiling.
"Is there a way for me to make it better?" Cora seductively smiled at Stiles, but he responded by shaking his head no. Then she started kissing his torso and ran her hands around it too.
Stiles sat up quickly, causing Cora to sit up as well, and grabbed her hands. "I really don't want to do this right now." Then Cora looked downward - Stiles followed her gaze and said: "Damn."
"Looks like he disagrees." Cora then went to the down under.
Stiles was so amazed that Cora was actually doing that. "Oh - oh my - oh my God." Then Cora positioned herself over Stiles. "I guess you want me to return the favor." And he did so.
Sheriff Stilinski couldn't help but to hear everything as he stood outside of his sons door. "Damn." He walked off shaking his head.
Minutes later
Stiles wiped the steam off his mirror from the shower him and Cora shared. He looked at her reflection as she picked up her underwear. "Hold up!" Stiles ran next to her in nothing but his boxers and took her underwear away from her. "Let me wash them."
"What about my pants and my shirt?" She asked as Stiles began to walk out of the room.
"Just wear a shirt and a pair of shorts of mine." He stopped at the doorway and answered her and jogged off to the laundry room.
"If Derek couldn't smell him on me before this, then he'll surely be able to smell him with his clothes on me."
After they got their clothes on, Stiles threw away the two condoms they used the night before. Yeah - that's right.
"Are you sure it was a good idea for me to not use a condom in the third round last night?" Stiles asked her quizzically.
"Don't worry, you can't get me pregnant - remember?"
"Yeah, but how is that?"
"Because I was born a werewolf. My DNA is a perfect combination of wolf and human, I was never just human to begin with, so your DNA has to have at least SOME wolf in it to be able to impregnate me."
"Right." Then Stiles walked up to her slowly and put his hand on her shoulder. "Do you think Jennifer told Derek already?"
"I hope so." They hugged each other right then.
"Should I let Derek or Scott change me?"
"Scott. So that way you won't be apart of Derek's pack and he won't be able to make us separate."
"Yeah, but you're his Beta. Shouldn't you listen to him no matter what?"
"Well - I technically have a new Alpha over me now." She started tracing a circle on Stiles' chest with her finger.
"How am I your new Alpha?" Stiles pulled her away so he could look at her as they talked.
"Derek is still my pack Alpha and I have to listen to him, but now I have more free will against him with you being my 'new' Alpha." She air quoted with her fingers.
"How am I your 'new' Alpha?"
"You are technically my - sexual Alpha and I'm technically your Bitch." Stiles' pants got tighter right at that moment.
"I'm your and you're my what now?"
"You heard me."
Stiles sat down in his chair and said: "Take off your shirt and bra and jump up and down for me." He motioned his finger up and down pointing at her.
"No." She crossed her arms and glared at him.
Stiles looked her dead in the eyes. "Now." He said demandingly. Cora's face turned red and she took off her shirt, then she began to undo her bra. "Whoa whoa. Stop, I just wanted to see if that would work." Stiles couldn't help but to smile at her.
Then Cora threw the shirt at his face. "You're such a perverted jerk!" Then she snatched the shirt out of his hands and put it back on.
"Hey." He grabbed her shoulder. "I'm sorry." He looked around her at her face.
"It's ok." She huffed.
Stiles smiled, kissed her cheek, and pulled her out of the room. "Lets go see Derek."
At Derek's Hideout
Peter walks down the spiral stairs as all the couples make out in different parts of the building. "I smell sex." He said coming down the stairs.
"Sorry." Derek stops kissing Jennifer for a second.
"Not you two." Peter points at them.
"That would be us then." Isaac says as he holds up Allison.
"Not you two either."
"Us?" Aiden asks while Lydia kisses his neck.
"No."
"Us?" Danny asks with his arms around Ethan.
"No."
"Is it us?" Emily asks as she lays in Scott's lap (Emily is an OC - just imagine Emma Roberts).
"No. It's them." He motioned his head to the door as he stood in front of the stairs in front of the door. The door opened up to show Cora and Stiles.
"The hell?" Isaac asked as he looked at the couple.
"Daaamn." Ethan and Aiden said at the same time.
"Uh-Oh." Scott looked back at Derek.
Derek sat Jennifer on the table, stood up, and asked: "What the hell is this?" He pointed at the couple.
"You didn't tell him?" Cora asked Jennifer.
"I was about to. I didn't think you two would get here so early." Jennifer replied.
"Wait." Derek said. "You knew?" Talking to Jennifer. "And you didn't tell me? And you." Talking to Cora. "You went to her first instead of me? I-I…" He exhales loudly. "I'm going to kill you." He pointed at Stiles, transformed.
"Hey uh, Scott?" Stiles looked at his best friend.
"Sorry. I can't help you here." Scott told him.
"You suck as a best friend!"
"You know you can't kill him, Derek." Peter said getting in front of the Alpha. "You know what you HAVE to do though."
"You're right." Derek said. "Come here, Stiles. Time to join the pack."
"Now, I'll help." Scott jumped up next to Stiles.
"Perfect, cause Cora told me to let you bite me."
"STILES." Cora scorned her boyfriend with a death glare.
"Idiot." Peter hung his head down in shame.
Then they all heard a roar, they looked back, and saw the twins together in their giant form. "We'll take him." He - It - They…..whatever said.
"Run!" Scott yelled and him and Stiles ran out of the room.
Derek stepped forward to run, but Peter tackled him to the ground. "Can't let you do that, Derek." Then Derek roared at him. "I'm sorry I'll get up." Peter walked away from him, but Allison jumped on Derek's back growling and Derek tried to get her off.
"I gotcha, Babe!" Isaac ran up, dead legged Derek, and held his arms back.
Then Emily and Cora roared at the giant as it roared back before they began to fight.
But then they all heard Stiles scream in pain. They all ran out the door and saw Stiles staring at his bite and Scott with blood in his teeth.
"Alright a new member to the pack." Emily said as her, Allison, Ethan, and Danny skipped toward Scott and Stiles. Yes, Emily, Allison, and Ethan are apart of Scott's pack. Yes, Emily and Allison were bit by Scott. And no, Danny is not a werewolf at all. "Welcome to the pack." Emily stretched her arm out to help Stiles up.
"Why are yours and Allison's eyes silver?" Stiles asked.
"That's to signal that they are Betas of a True Alpha you idiot." Peter said.
Stiles stood up and Cora ran up to him, but stop midway. "Whoa you stink." She said waving her hand in front of her face.
"How?" Stiles asked.
"It's the stench of another pack." Derek said.
"The only question is, if Cora will be able to get over the smell like Isaac did for Allison." Peter pondered. Then Cora broke all doubts and hugged Stiles and he hugged her back.
"So, when's the next full moon?" Stiles asked everyone.
"Tomorrow night." Scott answered him.
Stiles smiled sarcastically and said: "Perfect!"
