Hahn's eyes changed when Callie said she had something to say. She seemed… worried. And not about the keys… but about what Callie was about to tell her.
"I… I just wanted to say…" Callie looked into Erica's eyes. They were tired, sad, worried, but they were concerned. They were listening. And they turned her on so much more than Sloan's. She took her chances and looked down at her lips – also so much better than Sloan's. And it was then that she realised she didn't have to say anything.

"I just wanted to say…" She breathed, taking that one step further and curling her fingers into Erica's hair before pressing her lips against hers, opening them slowly, praying she would react.

She did.

It took a couple of seconds, but she did. She felt Hahn reach her hand up and cup the side of her face, and she felt her mouth moving against her own. Callie pulled back just a fraction of an inch to look into her eyes. The worried look was gone, and Erica has a small smirk on. Callie returned it and went to kiss her again, sliding her tongue into Erica's mouth.

Just a few minutes ago she was worried about people seeing them together. She was worried about Mark's reaction. Now she had her arms wrapped around this beautiful woman… this beautiful, talented, sexy woman, and she didn't give a damn on who was watching.

She knew they looked like a pair of teenagers – very gay teenagers, making out like this next to a bench. And quite frankly, she was ready to prove that she wasn't a teenager by throwing Erica down onto that bench right then and there, but instead Callie pulled her mouth from hers and rested her forehead against Hahn's. "So…" She said, her voice raspy and high-pitched. "Your keys?" Callie looked up at her from behind her bangs, smiling and biting her lip. Erica let out an airy laugh, a smile was already spread across her face.
"If we go to your place, I won't need them."
Callie smiled mischievously, and raised an eyebrow in response to the bold request. "Let's go." She said, taking Erica's hand in hers and wrapping her free one around her arm. While they walked to her car she leaned her head on Erica's shoulder, who propped hers on top. Out of the corner of her eye, Callie could see Mark smirking at them. She smiled at him graciously before letting go of Hahn to get into her car.

She didn't get far before Erica grabbed her arm and pinned her against the side of the vehicle, and started kissing her again, wrapping her arms around her waist, pinning her there. Callie immediately complied, twisting her arms around Erica's neck, pulling her closer. Another teenaged move, but…

teenagers knew how it was done.
