The captain's sister

Flirt.

Alison's apartment:

Bucky lay in the bed next to Alison. He smiled sleepily as she tightened her grip around his waist. His eyes shot open at the sound of the front door opening.

"Ali?" Steve's voice asked "Buck?"

"They're probably asleep." Tony's voice said

Bucky heard footsteps getting closer to her bedroom and slipped out of the bed. He slipped on his pants and moved to the door. He could see Steve's face from the crack in the door. There was no getting out of this. He slipped out the door, clicking it shut. Steve, who'd been talking to Tony turned around.

"Did you just-" he started

"Leave your sister's bedroom?" Bucky finished "Yes."

He thought it better not to lie.

"Why?" He asked

"She had a nightmare last night." Bucky responded, telling a half truth. "about the train."

Steve sighed and went to walk past Bucky to open Alison's door.

"Yeah, don't do that." Bucky chuckled

Tony shook his head in amusement.

"And why not?" Tony laughed

"She's um....not dressed."

Steve turned and hit his head on the wall.

"Bucky." He groaned "Why?"

"She started it." He defended "I just...finished it."

"Oh my god, James shut up." Steve laughed.

He didn't know how to be truly angry at him but he could be mortified by what he was saying.

  "What?" Bucky laughed

Ali stirred inside the bedroom. She could hear the three men laughing in the hall. She groaned and sat up. She crawled out of bed, wincing as the blanket brushed her leg. She looked down to see a hand shaped bruise on her thigh.

    "Pants then." She mumbled, walking to her wardrobe.

She pushed back the skirts, digging for a pair of comfortable pants. She smiled, reaching back to a package from her birthday she hadn't opened. It was from Natasha. She ripped open the package and held out the white body suit. She laughed and tossed it on her bed as she grabbed a pair of jeans and a body hugging sweater. She opened the door to Bucky's back and pulled him to her, snuggling between his shoulder blades. Steve watched as a wide smile crossed Bucky's face. He didn't think he'd ever seen Bucky that happy.

   "Going somewhere?" Tony asked, spotting her fully dressed

  "No." She said

"Then why so dressed up?" He teased

"I mean I could have come out here in my nightgown." She replied.

Bucky's smile dropped slightly.

  "Yeah?" Tony flirted playfully. "that would've been a sight."

The man was happily married but that didn't change his personality. He'd always be flirty and playful.

Steve chuckled quietly and walked into the kitchen. He knew Bucky's possessive side well.

  "I bet." Ali laughed, teasing Tony for his perverted attitude.

Bucky growled and Tony put his hands up in surrender, following Steve into the kitchen. Bucky turned to Ali, grabbing her shoulders gently.

"Mine." He said firmly.

He knew by the little smirk Ali gave she wasn't going to stop flirting.
