A plot bunny that entered my head when I was planning out my first fic, Turn Back. It would not leave me alone, so I typed it out, and am really happy with how it turned out. Enjoy. :)

I dedicate this oneshot to Crooked, who makes me giggle. (I see you twitching there... ;D)

Pairings: BlackbirdxKathryn, and some SamxMikaela thrown in too.

---------------------------------------

"Ooohhh, that tickles!"

"Hey! Hold still! I can't do it with you squirming!"

"Fine… oh!"

Kathryn held the brush away as Blackbird jerked underneath her hand. "Honestly!" she said. "I'm never going to finish it at this rate!"

"I'm trying to hold still, but it tickles!' Blackbird complained.

Bumblebee walked into the rec room with Sam and Mikaela at his heels. "Hey there!" he said happily. "What'cha doin'?"

Kathryn began to stroke Blackbird's quarter panels.

"What…" he said. "What is that for?" Kathryn grinned.

"It's to keep you still," she said, carefully lowering the brush toward the stenciled lines. "Is it working?"

"Yes…" Blackbird said dazedly.

"What is that?" Sam said, coming over to look at Blackbird's quarter panel. He noticed that the old motto, "To punish and enslave," had been removed. In its place was a series of faint markings in a curling, elegant design. Kathryn was holding a very thin paintbrush and tracing over the curves with white paint. A tiny pot of white paint, along with a few other items, was resting on top of Blackbird's trunk. Sam recognized them.

"Are you… pinstriping him?" he said. Kathryn grinned.

"Yup," she said.

"Cool," Mikaela said, coming up behind Sam and putting her arms around his waist. "Nice design."

"Thanks," Kathryn said. "It's really hard to paint along the lines, though. Especially when he keeps moving."

"Hey!" Blackbird protested. "I've been trying to hold still, but it tickles!"

"Why are you pinstriping him?" Bumblebee said.

Kathryn gave them all a look.

"Everyone knows you can't be an ex-con without a tattoo!"
