#2: Acid causes explosive reactions

It was an ordinary Wednesday morning. Tony stared out of the windows at the miserable grey sky. He was still feeling crap, recovering from a week long bout of the flu.

"Gear up!" yelled Gibbs, coming into the squad room with his morning cup of coffee. Tony grabbed his stuff.

"Not you, DiNozzo. Abby's lab. She needs help processing all the evidence. McGee, David, Now!"

Tony watched mournfully as they all left. Gibbs was just making sure he was 100% before he went back into the field, but he wished he was with them. He headed for Abby's lab.

She was nodding her head along to the beat of the music when he entered her lab.

"Hey Tony, oh shit!" She had spilt some sort of liquid down her top. She ripped her t-shirt over her head to get it away from contact with her skin.

"Sulphuric acid," she said, as a way of explanation.

Tony just stared at her. She was wearing a red lacy bra that boosted her larger than average assets. Her hair was a mess from pulling her top off, and the absence of it revealed the top of a red lace thong poking above the top of the waistband of her tight black jeans. She looked amazing.

"Whaat?" she asked, wondering why he was staring at her.

Before he even knew what he was doing, he had strode over to her, and kissed her passionately. A few minutes later, they broke for air.

"Wow," she said, "I've been waiting for that since we met, but I didn't think spilling sulphuric acid down me would do it for you. That's hinky!"

He shut her up by kissing her again.

In weeks gone by, he wondered how nobody else figured out they were together. Whenever he was with Abs, he couldn't help but stare at her ass and her long, long legs. She had this special sexy smile she kept just for him that got under his skin. He knew, eventually, they would have to tell the others, and Gibbs, about them, but he was scared he would lose his job, and possibly Abby in the process. He knew Gibbs thought of Abby as a daughter. If he found out what, or more accurately who, she did after hours, he'd most likely kill him.

Two nights later, at half ten, when he was sure everyone had left, Tony snuck down to Abby's lab. She was waiting for him in her office in her underwear, the red lacy set – his favourite. When he entered, she threw herself in his arms, and he kissed her passionately. She shoved the shirt off his shoulders and unzipped his pants.

Gibbs came out of MTAC. The squad room was empty. He expected his team had all gone home. Abs had mentioned working late tonight, doing her equipment inventory for the tax people. He thought he'd just pop down to her lab and say good night.

Her lab was empty. There were lights on in her office, so he pushed open her door. She wasn't in there. She must have finished up and left. He flicked off the lights and left.

Three minutes later, Abby and Tony fell out of the cupboard.

"Phew, babe, that was close."

"I know," she replied, and kissed him again.

Gone eight the next evening, Gibbs, Ziva and McGee finished their paperwork at about the same time. And all headed for the elevator together. The doors opened and Gibbs made to step in. What he saw made him freeze.

Abby and DiNozzo were pushed up against the corner, kissing as if there was no tomorrow. Abby's arms and legs were snaked around Tony's torso. As they all watched, speechless, they heard the chinking of DiNozzo's belt being undone and his pants being unzipped. He started to push Abby's skirt up. It took Gibbs less than two seconds to realise the couple were planning to have a quickie in the lift, and they were both oblivious to the doors having opened. He grabbed Ziva and McGee by their elbows and pulled them into the lift. The doors shut behind them. Still the couple didn't notice them. Gibbs waited for the lift to move before he flicked the switch that suspended the elevator between floors. The lift lights dimmed. Abby lifted her head from Tony's and gasped at the sight of them all standing there. She got down from Tony and straightened out her skirt. Gibbs heard Tony's pants being zipped back up and his belt fixed. Only then did the young agent turn to face them. He was breathing heavily and his cheeks were scarlet, but he looked defiant.

"WHAT THE HELL ARE YOU DOING?" yelled Gibbs.

"Tony," said Abby, cheekily, and then stuck her tongue out.
