It's my first fan fic. If I get enough feedback, I might continue. Post 9x24

Dr Arizona Robbins is close to desperate; she needs a business analyst to help manage her tiny biomedical company before the bank takes everything she's ever worked for. The one person that seems capable of taking control is Callie Torres. But is Callie interested in taking control of more than just Arizona's finances?

An affair rocked Callie's world when her girlfriend Erica cheated on her. Devastated - still with Erica - she finds comfort in a person who promised they would never see each other again. Circumstances caused Arizona to break that promise and they find themselves breaking the one rule they made that night. One night turned into just sex. And just sex... turned into something more.

Callie and Arizona have put the trauma of the last few months behind them and are gradually healing their relationship when a seemingly innocuous incident threatens the very foundations of their love and the possibility of a future together.Post S6. A/U
