035. Multitasking

"Donnie," Leo said, knocking lightly on the lab door as he pushed it open, "I just wanted to - "

"NO. I mean, 'Hi!'"

Leo stopped in his tracks with a dubious expression.

"Hi, Leo, I uh - what, uh, what, uh, what's up?"

Leo rolled his eyes. Donnie was so spacey when he was working. He was hunched all the way over his keyboard, not even looking his way anymore, his nose not two inches from the monitor, with the intense, slightly crazed expression he got when he was on to something big.

"Look, I know you've got a lot going on right now, and I hate to just dump this in your lap - "

"Aaahhh yah, yah, I kinda do, so uh…how can I…how can I…what?"

"The boiler's making that weird noise again," Leo said, "And you need to adjust the sensitivity on the smoke alarm. The incense keeps setting it off when I'm trying to meditate."

"Uh-huh, uh-huh. Boiler. Smoke arl-larms," Donnie slurred, staring intently at his monitor again, where a 3D model of a molecule rotated slowly. "Got it. Thanks, Leo."

Leo squinted, and eyed Donnie's clenched jaw, and hunched posture.

"What's with you? How much sleep did you get? That is, if you're even getting any."

"What?" Donnie asked, turning from his monitor, his eyes wide.

"Sleep, Donatello," Leo said, sarcastically, "That thing mortals do?"

"Ah, right!" Don nodded with a forced smile, "Okay! Sounds good!"

Leo shook his head and scoffed in disbelief.

"You're unbelievable! You haven't heard a single word I - "

"GOD! Damn!"

Leo's eyes widened in shock as Donnie pounded a fist on his desk, then quickly flattened his palm.

"Damn, Leo, you - are so right! That was just - rude, and I am SO sorry about that, but I am really…close to a breakthrough here, can I - uh, get backtoyouonthe boilURRR - HUR! AHEM!"

He coughed forcefully into his fist, and then thumped his chest a couple times.

Leo arched an eyebrow.

"Are you on drugs?" he asked, flatly.

"No?" Don asked, as if trying to remember.

"I hate when you take those stupid trucker pills instead of sleeping. You get all - twitchy."

"Yeah, I - UGH," he blurted, "I'm just so…emBARassed about it? I mean you've…warned me about this a hundred times, and I just…Mm!"

Don clenched his fist again and shook his head fiercely.

"Well, alright, I mean - don't beat yourself up," Leo muttered, feeling a little guilty for scolding him when he was asking for a favor. "Look, you're obviously stressed out, I'll come back later."

"THANK YOU!" Don blurted, "Leo, uh - thanks. Good - good talk."

Leo rolled his eyes and turned to leave.

"Oh, hey, Leo? Lock that, would you? I really need to…focus."

"Yeah, fine," Leo muttered, hitting the button on the doorknob, "Whatever."

"You're the best!" Don grinned, giving him a thumbs up.

Leo pulled the door shut behind him. For a moment he stood in the hallway and puffed his cheeks out, shaking his head.

"Weird," he whispered to himself.

He went off to the kitchen to see if there was any leftover pizza, or if Mikey had gotten to it already.

Donatello sagged bonelessly into his seat, his head lolling backwards over the back of his rolling desk chair.

"'Don't lock it,' you said," Don mumbled sarcastically, "'It'll be fun' you said!"

April sheepishly climbed out from under Donnie's desk.

"Well, somebody enjoyed it," she smirked, wiping the corner of her mouth with her thumb.

Don growled and pulled her into his lap. April let out a happy squeak. With a push of his legs, Donnie rolled them both over to the lab table, and sweeping some scribbled notes aside, he set April down firmly on her rump.

"Oof! Geez, Donnie!"

"We need to discuss your behavior, young lady."

"Oh, do we?" she replied fluttering her eyelashes teasingly.

"Mm-hm," Donnie smirked, running his hands up her legs, "You, have been very vexing, Miss O'Neil." He started fumbling with the button on her shorts with thick, green fingers, pleased to see April grinning and biting her lower lip, "And it is time to return the favor."

"Mm, by all means," April grinned, "Vex away."

There was a cheerful "shave and a haircut" knock on the lab door.

"Oh, COME ON!"

"Deeeeeeeeee?" Mikey asked, in a sing-song voice, "I was gonna make Chex Mix! D'you wanna - "

"FUCK OFF!" Donnie begged, half-involuntarily.

There was a brief pause from the other side of the door, and Don winced guiltily.

"Heeeeeeyyyyyy, April," Mikey called, sheepishly.

Donnie face-palmed.

"Hi, Mikey," April called, shaking her head with a broad, helpless grin.

"Sorryyyyyyyy…"

"It's okay, Mikey," April replied, stifling a giggle. Donnie was gently banging his forehead against the lab table between her legs.

"Soooo…do you guys still want Chex Mix or?…"

"MIKEY."

"Right, I'll just - Have fun! Have good sex!"

"MIKEY!"

"OKAY, sheesh!" They finally heard him walk away, muttering to himself.

Donnie made weary eye contact with April.

"Can you divorce your siblings? Is that a thing?"

"Tch! You don't mean that," April scolded, prodding him in the shoulder. Donnie just wrinkled his nose and gave a little sideways nod, like he might be considering it.

April grinned, shook her head, and started wriggling out of her shorts. "Hey. Let's focus on the task at hand, please."

"Well, if we could get five minutes…"

"Five minutes?" April said, with an arched eyebrow.

"Well," Donnie smirked, turning a bit red, "Okay, bit more than that…"

She giggled again, as he tossed her clothing aside and draped her legs over his shoulders.
