AN - I saw someone's headcanon on tumblr...and this happened.

From tumblr - Everyone's waiting in the dark for Maura's surprise birthday party but she stumbles in the door already making out with Jane with her shirt half off and Maura's saying, "take it off, take it off" as they stumble through the doorway and they click the lights on and everyone's "…"

Maura's like "surprise?"

Maura's back slammed into the front door, Jane's lips attached to her neck. Jane pulled back just long enough to gasp out "Keys?" Maura gestured to her purse hanging off of her elbow before launching herself back towards Jane, ripping her buttons open, clawing at her ribs.

Jane managed to find the keys, but dropped them. "Maur – Maur – stop it for a sec – Maur – I dropped the keys."

"Mmmm don't care, don't stop." She kept on sucking Jane's neck, thoroughly intent on leaving several marks, nipping and biting her way across her collarbone.

"Maura, do you want to do it RIGHT here? I do not want to arrest myself for public indecency." Maura's hand snuck down the front of Jane's pants, only to be pulled out with a huff from Jane. She ducked down, grabbed the keys, and crammed the proper one into the keyhole, all while Maura continued her assault on Jane's neck, shoulder, and pants.

Jane grabbed Maura and pulled her up, wrapping Maura's legs around her hips, before shoving the door open.

Stumbling through the door, Maura yanked at Jane's shirt. "Take it off – mmm Jane – TAKE. IT. OFF."

Jane pushed Maura back against the door while Maura shoved the rest of Jane's shirt almost completely off, and Jane had her hands up Maura's shirt and into her bra, moans escaping her mouth into Maura's.

The lights clicked on.

Angela, Tommy, Frankie, Frost, and Korsak stood with their mouths open, Angela's beer shattered on the floor.

Maura quickly climbed off Jane and stood in front of her. Jane stood with her mouth open, too stunned to fix her shirt.

"Um…surprise?"
