The plan was simple enough. Get in, grab the Mutagen, get out. Donatello wasn't sure how he ended up in a cell in the basement of Foot Headquarters.

"Enjoying your stay, Donatello?" A silvery voice asks from out of his line of sight.

His cell, if you could call it that, had nothing in it aside from himself. It wasn't very spacious either, the edges of his shell rubbed against the damp walls and the place smelt of mold. In short, he wasn't enjoying his stay.

Karai appeared in front of the bars, her smile mocking him. "No? I'm sure it's not that bad."

He scoffed and russet eyes met hazel briefly, "Why don't you join me and see how 'enjoyable' it is?"

"Tempting." The amusement in her voice was obvious. Donnie scoffed yet again. Why'd he have to be the one captured? Not that he'd want one of his brothers to be in the Shredder's lair, but they'd probably be doing better than him.

His body jerks to the sound of the cell door opening and slamming closed. Karai smirks down at him, standing mere inches away. Donnie didn't know what to think as his new cell mate sat down across from him, still smirking. He didn't know what to do, the situation was far from normal.

"I don't know. I don't mind it in here." she commented, observing the cell as if it was an actual living space. "It's cozy."

He decided to play along, "Yeah, I guess. Could use a few more colors here and there." Karai nodded and placed her hand on her chin, as if stroking a beard.

"Green would look nice." Something in her voice seems off.

He feels surprised for a moment, Karai notices. She leans closer to him, until her nose is nearly touching where his would be. Her arms come forward and place themselves on either side of his legs.

Karai's voice is smoky as she whispers, "What? I really like the color green. Does that surprise you, Donnie?"

Donnie's mind is running a mile a minute 'What is she doing? Why is she this close? Is she flirting with me? What do I do? WHAT DO I DO?!' Karai can practically hear the gears in his head turning, she smiles a sweet smile.

"You're overthinking things." She whispers.

Karai closes the gap between their lips.

Donnie doesn't know why he kisses back, reflex maybe? But he does. Their lips part and the kiss deepens as tounges meet. She tastes like cherries, and the kiss isn't rough or forced. It's pleasant. He experimentally bites her bottom lip, he's rewarded with a small moan.

Somehow his mouth moves down to her neck. He licks and sucks until he can see light bruises forming. She moans again when he bites her collar bone. Karai lifts his chin back up and locks their lips together again. The next few seconds are the most confusing. One second he's making out with Karai, the next she's gone.

"Donnie?" Someone calls out from not too far away. It's Mikey.

He yells back, "Mikey? In here!" He's still looking around the cell though. Where could she have gone?

Mikey's smiling face appears behind the bars. "Hey bro! Lemme get you outta there..." The lock can't stand a hit from Mikey's nunchucks, it breaks. Mikey grabshis hand and pulls him out of the cell, locking him in a hug.

"We missed you bro! Come on, the others are waiting." He leads Donnie away from the cell, the ladder still confused and flustered. "Hey are you okay, D? You look a little red."

"Oh uh yeah, It's just a little hot in here." He waves it off and pushes his little brother forward.

"So where's everyone else?"

Meanwhile...

Karai's arms slacken and she drops down from the ceiling of the tight little cell. That was way too close.

But definitely worth the risk.

First (posted) story. I chose Donrai because I know it's not that popular of a couple, but all ships need storys (no matter the length) so, I thought I'd add to the Donrai pool.
