A/N: This chapter is all over the place but I hope you enjoy. :)

Chapter 4

Arizona eased her eyes open before jolting from the couch. How long had she been out? The sun had been tucked beneath the horizon for quite some time now. She looked at the clock on the entertainment center. She still had an hour to kill before going into work. The fatigue her body had felt before her nap had prohibited her from finishing any of her errands. Just as she had finished rubbing the sleep from her eyes, a small tap was to be heard on the front door of her apartment. She wasn't expecting anyone. Maybe Tim had forgotten his key.

She unlocked the door, finding the woman she had just yesterday wished away from her same woman that, just yesterday, spent a long night in her bed. Arizona smiled, happy to see Callie's pleasant face at her doorstep.

"Hi," Arizona hummed breathlessly, feeling that tingling tightness in her chest that Callie's presence always seemed to bring.

"Hey," Callie articulated, "you're brother is coming to stay with me tonight. I just came to get a few of his things."

"Oh," Arizona replied, her tone dull and sulky. She was slightly jealous that her brother could spend as much time with the Latina as he wanted. Especially all of that time in Afghanistan. She knew she shouldn't be jealous. Callie and Tim were risking their lives every single day for the freedom of our country, but her heart was still tainted with a hint of resentment.

"Can I come in?" Callie quieried, stepping closer to the blonde.

The moisture in Arizona's throat evaporated. She swallowed, trying to coat the area with saliva but failing miserably, "Sh-sure." The blonde and the brunette stepped inside, Arizona closing the door behind the two women. She watched intently as Callie gathered some of her brother's things. Arizona caught a glimpse down the brunette's blouse as she bent over to pick up something she had dropped. The blonde demanded that she tear her eyes away, but something this perfect could not be any more distracting.

Callie could feel blue eyes almost undressing her and she tried her hardest to pretend to be oblivious. When she bent over to pick up one of her best friend's discarded t-shirts, her eyes connected with darkening blue eyes that pooled with lust. Callie dropped the duffle bag from over her shoulder and lunged, desperate for the lips she was meant to kiss. Maybe none of this made sense yet. Maybe there wasn't any real explanation for what these two women were doing but they were under a silent agreement that they needed this. They needed each other.

Callie collapsed into Arizona's bed, her muscles weak from the workout the blonde had just given her. Both women lie with their chests to the ceiling, trying like all hell to regain the oxygen they never seemed to have when they were around each other in the first place. The sex was mind-blowing. There's no doubt in the world about that. Occasional moans were still slipping from pursed lips as they suffered through wave upon wave of aftershock. Any sudden movements could send their bodies convulsing in yet another orgasm.

"Shit!" Arizona exclaimed, shooting up from bed. She shuffled quickly out of bed, pulling a fresh pair of panties on, "I've gotta be in work. I'm late. Hunt is going to kill me."

Callie eyed the blonde as she shuffled through a drawer trying to find clean scrubs. She didn't know if she should start dressing as well. She felt under the covers. Was that the thong from last night or the fresh one from this morning wrapped around her ankle? Maybe it was Arizona's. She didn't know, so she decided to leave yet another pair to float around between the sweat-stained sheets. She turned the jeans she used to be wearing rightside out and yanked them on.

"I have to go," Arizona told Callie in a rushed voice, "you can let yourself out…or stay. I…I'm sorry to have to leave."

Callie's eyes fell to the floor as Arizona ran back and forth in her bedroom picking up various objects and jamming them into her bag.

Arizona stopped abruptly, seeing the sadness in the Latina's eyes. The blonde grabbed a warm hand, bringing it up to her lips , "We'll talk about this later, okay?"

Callie half-heartedly smiled, pleased that Arizona could read the Latina like a book. She knew they had to discuss whatever 'this' was sooner or later.

But just like that, Callie was left alone in the blonde's apartment. She took her time getting the rest of Tim's things together. There was something about this apartment that made Callie feel safe and welcome. She examined the photos hung in the living area of the small abode. A photo of the blonde and her late mother was beneath one of her and her brother. She frowned, remembering the story that Tim had told her about the day their mother passed away from cancer. Barbera Robbins was the queen bee of the family. Everything slowly started falling apart when she exited the world. Callie could definitely relate to the tragic death, losing both of her parents in a car accident just before she entered the service. She never really had time to mourn their deaths, spending the first three months subsequent the accident situating their finances and obeying their will. It wasn't two weeks after settlement that she was drafted and sent in for boot camp training.

Callie swallowed the lump of sadness that formed in the center of her throat and took a deep breath. She finished gathering the last of Tim's things and exited the apartment.

"Hey!" Arizona heard a very firmiliar voice call from behind her.

She spun on heels, only to find her very best friend standing with open arms, prepared for a hug. Arizona gratefully accepted the arms around her, "Hey, Teds!"

"How is everything? I heard Timmy came home! I can't wait to see him," she articulated excitedly. Arizona and Teddy Altman have been friends since graduate school. They dated through pre-med and decided that they should be strictly friends after almost three years. Teddy would always have a place in her heart for her best friend despite her engagements to another woman.

"Yup, he's home and settled. You'll have to come by and see him. He'd love to see you," Arizona suggested seductively, nudging her friend in the arm. The Peds surgeon would never let her buddy live down the time she fell in bed with her little brother. It made Arizona's skin crawl knowing that she and Tim have shared a woman, so this is how she coped.

Teddy's skin shivered at the thought of that drunken accident, "that was one time and never again," she told her the shorter blonde firmly.

"What was one time?" someone chimed into their conversation, making the duo a trio.

"Nothing!" Teddy quickly replied, "hey, babe." She leaned in an kissed the woman firmly on the lips.

The brunette smiled at her fiancé with suspicion in her eyes, "hey."

"What are you doing tomorrow night?" Teddy questioned Arizona, ignoring the look her other half was giving her.

The shorter blonde pursed her lips in thought, leafing through her mental calendar, "Not a thing."

"You should come by Joe's with us," Teddy took the brunette's hand and gave it a reassuring squeeze.

"I'll be there," she articulated. 'but not without my own brunette,' she thought to herself.

Callie was nestle into the crook of her best friend's neck, something she'd always done when she had a lot on her mind. She wished that she knew what all of this meant. She knew Arizona cared about her. Or maybe the blonde wanted to let her down easy the next time they spoke. Callie was only sure of one thing. She didn't want to be a booty call.

"I can hear your gears churning, Cal," Tim said matter of factly, breaking the woman from her thoughts.

"No, you can't," the Latina insisted in a flat tone.

Deafening silence could be heard now. The only noise was coming from the television at the foot of Callie's bed. Callie tried to think of a quick topic to change the subject, but the inevitable was headed her way and she knew it.

"It's my sister, isn't it?"
