Best Friend's Sister (Puck/Finn/Sarah)

"I said I'm coming!" Puck hissed as he walked to the door and opened it. He furrowed his eyebrows when he saw Finn.

"Dude, I have to talk to you about something." Finn blurted.

"So talk." Puck nodded.

"Wait." Finn said. "Do you know already?"

"Know what?" Puck wondered.

"About me and Sarah." Finn muttered.

"My sister?" Puck asked as he grabbed Finn by the shirt and shoved him against the wall. "Seriously?!"

"It's not like I planned this." Finn said softly.

"She's my little sister." Puck shook his head. "And until, like, last week, she was basically yours, too."

"I know." Finn replied. "And I'm sorry."

"You're sorry." Puck rolled his eyes.

"When you and Quinn got together-"

"Quinn isn't your sister." Puck interrupted. "There's a line, dude. You don't date your bro's exes or sisters."

"So it's only okay if you date your bro's girlfriend while he's dating her?" Finn questioned Puck.

Puck took a deep breath and punched Finn in the face, knocking him to the floor. He continued hitting him while Finn fought back.

"Puck, stop, wait." Finn said as he and Puck wrestled on the floor. "Let me explain."

"Explain how you're fucking my little sister? I think I got it." Puck responded.

"Puck." Finn repeated, dodging Puck's punch and moving away. He quickly stood up and looked at Puck.

Puck got up and looked at Finn.

"It could be worse." Finn joked. "It could be Beth."

Puck clenched his jaw. "Stay away from her."

"You know I will." Finn nodded.

"No I don't." Puck said. "'Cause I thought you'd stay away from Sarah."

Finn bit his lip.

"Talk." Puck commanded. "'Cause once Quinn's home, you're gone."

"Me and Sarah didn't do anything." Finn began. "We've just been hanging out. I told her I wanted to talk to you before anything happens."

"So you want something to happen?" Puck asked.

"Not if it'll ruin our friendship." Finn shook his head.

"Then don't." Puck said. "Please don't."

"Okay." Finn replied.

"Okay?" Puck repeated.

"Okay." Finn confirmed. "Our friendship is more important than a possible relationship. Besides, we almost lost it when you got my girlfriend pregnant."

"You're never gonna get over that, are you?" Puck wondered.

"Never." Finn smiled.

"You're really okay with this?" Puck questioned Finn.

"I'll find another girl." Finn shrugged. "There's only one Puck."

"Thanks." Puck said. "And, uh, sorry for kicking the crap out of you."

"I got some good punches in, too." Finn pointed out.

"We cool?" Puck wondered, putting his hand out.

"We cool."
