Prompt: Tony/Abs/Gibbs, AU Gibbs is a gangster during Prohibition and Tony owes money

The raven-haired girl in the black flapper dress led him into the back room. Tony noticed that one of her numerous strings of beads had a skull-shaped charm. He hoped he wasn't making a mistake.

When he saw Boss Gibbs, Tony did his best to control his panic. The man sat there in his leather chair, sipping bourbon from a glass, the kind that Gibbs himself was illegally manufacturing, listening to Artie Shaw on his phonograph. The rich fabric of his blue pinstripe suit brought out his bright blue eyes, which were fixed on Tony in a way that had made many lesser men crumble. The woman sidled up to the silver-haired-man and smirked at Tony.

"What's he owe, Abs?" Boss Gibbs said.

"$8,175.34, including interest. His speakeasy got shut down, and he's been on the lam from the coppers. Hasn't made a payment since."

Abs had the mind for money, everyone knew. The G-Men couldn't pull a Capone on Gibbs, since all the numbers were stored up in Abby's pretty head, and she sure wasn't talking. Like most suppliers, though, the interest rates were not exactly standard -- Tony had originally owed only $240, but compound interest was a bitch.

Tony swallowed hard and said, "If I could just have more time -- "

"More time?" Gibbs said in a low voice, with a terrifying quiet.

"It's the cops, they - "

"It's you, DiNozzo. I gave you the finest bourbon that's still getting made in this country, and you get to be the most beloved speakeasy owner in the city. But when it goes south, you think that means you don't have to pay what you owe me?"

"Of course, I owe you. And I'll pay you back, I just don't know when. I -I'm sorry boss."

Gibbs narrowed his eyes and said, "You think I want your apologies? Apologies just show weakness."

Abs leaned over then and whispered in Gibbs' ear, "Please don't shoot him, Gibbs. He's so pretty."

"What'd you have in mind, Abs?"

She looked at Tony and smiled wolfishly. "How about you pay us back some other way, pretty boy?"

"Sure - anything - um, anything you want, but - wait, what exactly does that mean?" Tony was scared to ask but didn't have much of a choice.

Abby looked at Gibbs who gave her a quick nod of assent. "You're on the lam. We hide you in a safehouse. But in exchange, we get to do anything we want with you."

"Anything," Gibbs repeated in a gravelly voice, and Tony had to do his best to not tremble.

Tony didn't want to think about the kind of stuff that these two might come up with, but he knew he had no choice. "Okay. I mean, yes, of course. I'm grateful for the opportunity to pay you what I owe, boss."

The next night, after Tony had been trussed up like an animal on the safehouse bed, after Abby had used her flogger on him for nearly an hour, after he had gone down on Abs while Gibbs guided his head by jerking at the hair by his neck, after Gibbs had pounded into him while gripping his hips hard enough to bruise, Gibbs threw Tony to the hard wood floor and said, "You're right, Abs. That was fun. How much does he owe now?"

"Well," said Abs, as she calculated, "You add the interest accumulated today, calculated at 120%, and then you subtract what he worked off tonight, and he now owes ... $8175.35."
