Birthdays

Cora turned sixteen two days, seven hours and 14 seconds ago she had repeatedly told Derek as she sat in the back of his FJ Cruiser as they drove to the Dunbar household. Derek half listened when Cora told him about the gift she had gotten Liam, her best friend, and birthday boy as of fifteen seconds ago Cora mumbled under her breath when they pulled into the driveway.

Derek sighed finally feeling relieved that he didn't have to listen to his baby sister anymore. That's when he saw her.

Y/N Dunbar, the love of his life and his partner in crime for the night, walked out of her parents' house with her baby brother in tow.

Derek had been in a committed relationship for five years now. With both being twenty-five, everyone had been asking when they would take the next step—marriage but the couple already lived together, basically had two teenagers of their own and a pack to worry about right now, to add anything or anyone else to their life would be complicated.

"Hey Baby!" Y/N smiled as her lips met Derek's as soon as she got into the vehicle. "I can't believe our babies are sixteen."

Cora rolled her eyes as Liam huffed in protest as they got situated in the car. This happened every year and every year Derek chuckled at it. Derek basically raised Cora since his mother's death and Y/N had taken care of Liam while her parents went through their divorce and hadn't stopped yet.

The plan of the night was like clockwork, they would go get dinner, pizza or tacos, and then they would end up at the bowling alley, which Derek hated, and lastly they would get ice cream and head home.

"So Pizza or Tacos this year?" Derek question as he started putting the car in reverse.

"Um...well...you see." Liam spoke; he always had this awkwardness about him when he was panicked, but as always Cora jumped in to save her best friend.

"We need to go to the drug store." Cora smirked as she eyed Liam up. "Birthday boy needs condoms."

Derek's face looked confused he slammed the car into park before he turned around; his eye brows arching upwards at the teens.

"For sex?"

Y/N busted out laughing; doubled over knees to her chest thinking this was the greatest thing Derek had ever said. Whereas Cora just looked at her brother eyes wide shaking her head most likely thinking how stupid was he?

Liam on the other hand looked down at his feet as he rubbed his fingers together the strong smell of anxiety coming off him.

"Hmm...yeah."

"With each other?" Derek spoke with a harsh tone in his voice.

That question made Y/N stop laughing, she looked to the teens in the back seat then to Derek, she finally realized that if their younger siblings were together and so were Derek and herself; well that would be awkward.

"What the...it's not like that." Liam stated putting his hands up in defense. "Her name is Hayden. I would never do that with Cora." He looked at his best friend. "No offense you are hot but just not my type."

Cora shrugged, "No biggie I'm holding out for Lahey."

"My best friend!" Derek snarled at his baby sister.

The rest of the drive to the drug store was in silence. Y/N couldn't help but snicker every time she thought of something that had just happened, Liam sat head down pretending to look at his phone while Cora took a million selfies trying to find the best provocative picture to post.

Once they pulled in Derek eyed Y/N as he started to get out of the car motioning for her to join him.

"There's no way in hell I'm going inside to help my brother buy condoms. Have fun boys."
