Arizona glided through the halls, smiling at people walking by; off in her own little world thinking about going to Callie's later that night.

"Arizona?"

A familiar voice pulled her out of the clouds and she peaked into a patient's room where a familiar face matched the voice.

"Kristen?" Arizona laughed as she gave the woman lying in the bed a hug, "What are you doing here? Are you okay?"

"Oh yeah, I took a pretty nasty fall off a motorcycle. Need surgery on my knee."

"I always told you those things were a death sentence," Arizona sat on the edge of the bed.

"Yeah well I never listened to you did I?" The woman placed her hand on Arizona's knee.

"Uh, hey, am I interrupted something?" Callie walked, tucking her hands in her pockets.

"No, sorry I was just leaving actually," Arizona sat up and walked towards the door, "It was nice to see you again Kristen."

-.-.-.-

Arizona waited down the hall until Callie came out of the patient's room. When she finally saw Callie walk out and turn the corner, she ran after her.

"Hey, I was actually down here looking for you," Arizona caught up to Callie.

"Oh yeah?"

"Yeah, so-"

"How do you know her?"

"Uh…" Arizona searched for the right words, "We dated, long time ago."

"Oh," Callie turned and kept walking, this time at a slightly faster pace.

"Are you mad? Don't be mad,"

"I'm not mad, I'm weirded out,"

"Woah," Arizona placed her hand on Callie's arm motioning her to stop walking, "Why are you weirded out?"

"Because she's my patient…and she's seen you naked,"

"Wait, who said she saw me naked?"

"She didn't?" Callie stared at the blonde whose face had gone wide-eyed.

"The point is…" Arizona quickly diverted the question, "…You've seen me naked so it doesn't matter."

"Yeah, okay," Callie nodded to herself as Arizona's pager went off.

"I gotta go," Arizona quickly placed a kiss on Callie's cheek and then she was gone.

-.-.-.-

"It's weird right? It's weird," Callie asked Mark as she sat in the cafeteria.

"Well I-hey!" Mark waved over Lexie who placed her tray next to him and sat down.

"Mark, its weird right?" Callie asked again.

"What's weird?" Lexie asked, taking a bite of her salad.

"My patient is one of Arizona's exes and it's weird that she's seen my girlfriend naked right?"

"Why would that be weird?" Lexie took a sip from her juice box, "She's only a patient. You work with one of her exes."

"What?" Callie choked on her food.

"Uh…oh god did you not know that?" Lexie slumped in her chair.

"Who?"

"Colleen."

"The Ortho nurse!?"

"In all fairness I shouldn't have used the term ex, I mean they only slept together-"

"Stop talking…" Mark whispered to Lexie.

"When did they sleep together?"

The table fell silent as Lexie and Mark exchanged glances.

"The night before she started working here," Lexie spilled out.

"Colleen was responsible for Arizona's sex injury!?" Callie got up from the table and walked away.

-.-.-.-

"Well, you know all about her exes," Teddy grabbed her coffee and started to pour cream into it.

"Sometimes I wish I didn't," Arizona took a sip from her cup.

"But you know and she doesn't,"

"So what, I just tell her about all my past relationships?"

"Don't just blurt everything out," Teddy placed the lid firmly on her hot drink before taking a sip, "Let her know you're an open book."

"An open book?" Arizona looked down at her pager that was suddenly going off, "Oh it's her, crap."

"Just be open and flash your super magic smile she's always going on about."

"Does she actually say that?" Arizona couldn't help but smile at the thought of Callie telling people that. Her pager went off again and Teddy gave her a look, "Okay, okay. I'll be an open book."

"Good luck," Teddy began walking away.

"Super magic smile?" Arizona asked again over her shoulder.

"Her words!" Teddy yelled before turning the corner.

-.-.-.-

Arizona made her way to the on-call room where Callie had paged her. She took a deep breath before opening the door and walking in.

"Okay! I know you said you weren't mad but I just want you to know I'm an open book," Arizona closed the door behind her and waited for Callie to say something, "I know about your exes and you don't know about mine, so in fairness you can ask me whatever you want."

Callie sat up from the bed and walked over to Arizona to say something but the blonde kept talking.

"And if it makes you feel any better I slept with her once, once! And it was bad, oh god I can't even begin to-"

"Stop. Talking." Callie interrupted. She reached for the string of Arizona's scrub pants.

"What are you doing?" Arizona looked down at Callie's hands untying her pants and then back up at Callie.

"What does it look like I'm doing?" Callie smirked as she let go of the string and Arizona's pants dropped to the floor.

Callie lifted her scrub top over her head, discarding it and pinning Arizona against the door with her body. She kissed the blonde, pushing her tongue into Arizona's mouth as she grabbed a handful of blonde curls. Arizona wrapped her arms around Callie's body, digging her nails into the brunette's back while Callie's knee pushed against Arizona's center. Callie's hands moved under Arizona's top as her lips traced the blonde's jaw line.

"C-Callie, we're at work…" Arizona managed to say as she focused on where the brunette's lips were going.

"Then I guess you better be quiet,"

Callie kneeled down in front of Arizona, lifting the blonde's legs and rested them on her shoulders. She pulled Arizona's panties to the side and stroked her tongue along Arizona's wet centre. Her tongue moved faster, flicking her girlfriend's clit. Arizona bit down on her shirt, trying to muffle the moans escaping her lips.

Arizona let out a final gasp and moan as her body trembled and her head spun. She slowly placed her feet back on the ground and looked down at Callie, who was smirking and wiping her chin with her thumb. Callie stood back up, allowing Arizona to taste herself on her lips. The blonde motioned Callie to lie on the bed as she removed her own top and walked over. She pulled Callie's pants off, along with her panties and pushed the brunette's legs apart.

Arizona crawled on top of Callie, pushing one of Callie's legs in the air and resting it on her shoulder. She slid her two fingers into the brunette and pumped them in and out, curling her fingers inside of Callie. The brunette's head tilted back and she pulled at the bed sheet underneath her. Arizona rested her head next to Callie's; biting her neck. Callie pushed her face into Arizona's shoulder and dug her nails in the blonde's back as her body released.

They laid side by side, their chests heaving as they tried to catch their breath.

"Remind me to get you jealous more often," Arizona laughed, rolling over to rest on her elbow.

"I wasn't jealous," Callie turned and looked at Arizona, "Okay maybe a little jealous."

"I have to go check on my patients," Arizona crawled over Callie, giving her a kiss before getting dressed.

"You're still coming over tonight?" Callie asked as Arizona opened the door.

"Without a doubt," The blonde smiled and shut the door behind her.
