Today was Halloween, and NCIS was hosting a Halloween party. It also happened to be a full moon. Abby, of course, was super excited and had talked everyone on team Gibbs into going, well, except for Gibbs himself. Gibbs wasn't a party person; he liked being alone in his basement, content with a sander and a bottle of bourbon. Abby had spent the whole day plotting and scheming to find a way to get Gibbs to go to the party. She had gotten a little devil's costume for Gibbs, using her master scientist skills to estimate his sizes. She had also called Gibbs into her lab as she planned on trapping him in there and begging him till he agreed, which always worked.

And it wouldn't be long till Gibbs got there.

When Gibbs finally walked into her lab it seemed that this was just an ordinary visit, so unsuspecting, so normal, Gibbs even greeted Abby with his custom greeting.

"Hey, abbs, what d'you got" There wasn't any case, but the words were just habit. And with those words Abby felt a slight guilt wash over her, she knew going to a party would probably be torture for Gibbs. But then again it was Halloween, her favorite holiday. And it would give everybody else a good laugh.

"What I got, Gibbs is an issue," Abby sighed. Gibbs was now concerned about what issues could she possibly have on her favorite day of the year.

"An issue for you," Abby said, pulling a remote out of her lab coat pocket and pressing a button causing the door to her lab to close and lock.

"Abby," Gibbs said warily, looking at the door and then back at her.

"Sorry Gibbs," Abby said with not a single apologetic tone in her voice as she reached behind her desk and pulled out a costume. It was a red button-up satin shirt with black slacks, a black belt with a big silver buckle, some shiny black shoes, long red knitted socks, a long red satin cape, and last but not least a pair of red horns.

"Abby, no" Gibbs said, taking a step away from her, wracking his brain for any way to get out of this.

"Please" Abby whined with a big bottom lip and puppy dog eyes.

"No" Gibbs looked around and spotted a bottle of super glue. `Maybe he could glue Abby in place, and then he could leave," he thought.

"Gibbs, please. For me," Abby pleaded again.

"I don't dress up" Even If he did, what good would it do anybody.

"Come on, Gibbs, one night, a couple of hours, you won't even have to dance"

"Dance?" Gibbs asked incredulously, "No way Abbs"

"Please, pretty please, with little devil horns on top" Abby came rushing towards him and engulfed him in a hug, knowing he was about to give in.

"Fine" Gibbs huffed and Abby bounced excitedly, handing him his costume and ushering him into the ballistics lab to change.

"Hey, Abbs, do I really have to wear the horns," Gibbs said, walking back into her office, dangling the horns from his pinkie finger.

"Yes, Gibbs, and you're supposed to tuck your shirt in too," Abby said, running over to him, grabbing the horns and placing them on his head, then reaching for his shirt and tucking it in. 'I should really teach Abby some personal space' Gibbs thought as Abby's hands pushed the shirt into his pants. When Abby was done she dragged him over to a mirror and Gibbs had to admit he didn't look half bad.

"Hey Abbs how'd you know my size," Gibbs asked, turning his head to look at her

"Ahh, a scientist never reveals her secrets," Abby smiled, wagging a finger at him.

"Okay, so how long do I have to be here?" Gibbs sighed, already bothered and wanting to go home.

"Oh, only till I say you can leave," Abby smirked.

"Wait here while I change" She started to make her way to the ballistics lab but came back and snatched the remote that controlled the doors off the table before heading to the lab. When Abby came out about twenty-five minutes later she didn't really look much different than she normally did.

"Okay, how do I look" Gibbs raised his thumbs at her and gave her a sad smile.

"Oh, come on, you can't be that miserable," Abby said, grabbing the horns that he had taken off and placing them back on his head.

"The party starts in about half an hour, and I've told all the guys in security not to let you out unless I've told them they can. Okay, Gibbs, so no sneaky exits," Abby scolded. "And the only reason there is half an hour of time to spare is because I needed to make sure I had enough time to sucker you into this, then get you ready and get myself ready for the party." Abby added as she started moving around her lab, cleaning little things, and putting stuff away.

"Well, I'm Gonna have to dock you some caf-pows for this"

"Awww come on Gibbs" Abby whined, although she didn't really care, getting Gibbs to dress up was way better than some caf-pows, she'll just have to mooch them off someone else for a while.

Once the half-hour had passed, Abby thought she had more trouble trying to get Gibbs to leave the lab than she did getting him to put on the costume.

Once they got to the gym, where the main party was being hosted - though there were other little gatherings happening on other floors - Abby went to go find McGee, and Gibbs B-lined it for the booze. Grabbing a couple of beers, then heading to a fairly quiet corner, he slid down the wall to the floor as he took off his horns and opened one of his beers.

Kate wasn't a fan of parties. She never had been, the only reason she'd ever go to one was because of a friend. And tonight, this friend happened to be Abby. Kate hadn't really spent that much time and effort on her costume, she just found some old clothes and slapped them together for a mediocre costume.

The outfit that she had put together consisted of a USC Trojans jersey, a pair of cut-off daisy dukes, a backward USC cap, and some white chucks with black knee-high socks. Not to mention the black lace bra that was totally visible under the jersey.

After about ten minutes of wandering through the hoard of people, Kate had spotted Gibbs in a corner, grumbling to himself and sitting in a puddle of red satin and empty beer bottles. It reminded her of high school dances, and he was the weird kid sitting alone in the corner, which I guess would make her the nice girl who would go and talk to the kid in the corner.

Anyway, was Gibbs in a costume?

He looked so miserable that Kate thought she would join grumbling Gibbs in miserable land since she wasn't having any fun either.

"Hey," Kate said as she sat down next to him.

"Hmm," Gibbs grunted, finishing off another beer bottle. He grabbed two more from beside him and offered her one.

"Ever the conversationalist," Kate remarked sarcastically, accepting his beer offering.

"Why aren't you over there with everyone else," Gibbs asked, ignoring her comment, opening another beer, tossing the cap to the floor with the rest.

"Because getting drunk with a bunch of people just seems so stupid," Kate sighed.

"Yeah," Gibbs chuckled, "yeah, I prefer getting drunk when there isn't a bunch of people around," Gibbs indicated to the hoard of people with his bottle. Kate turned towards Gibbs and crossed her legs; it was hard to imagine Gibbs ever being drunk.

"He says while drinking at a party," Kate said facetiously.

"Hey, this was not my idea. I do not want to be here," Gibbs said, indicating himself with his beer bottle.

"Did Abby sucker you into going too" Kate snickered, picking up Gibbs' discarded horns.

"How'd you know" Gibbs chuckled as Kate put the horns back on his head. Kate was surprised that Gibbs let her put the horns on him, but then again she didn't know how many beers he'd had.

"She's actually quite manipulative," Kate sighed, sipping her beer.

"Not only did she make me come, but she told all the guys in security not to let me out of the building," Gibbs said, pulling his knees to his chest.

"Really. Well, that makes two of us, but lucky for you, I have a plan," Kate broke off, leaving him in a sort of suspense.

Gibbs looked at her in a way that commanded her to go on.

"Well, what if we got on the roof using the access ladder in the maintenance closet, which we have keys to, and from there, we climbed down the fire escape"

And that's exactly what they did, they went up to the roof, then down the fire escape, and Gibbs would be lying if he said his cape didn't make it harder to climb down the tiny ladder. He thought about ditching it, but Abby would be mad - well, madder - if he lost it.

On their way to the parking lot, they spotted Abby and McGee leaving the building. Gibbs grabbed Kate quickly and swung them around a corner where he was sure they could not be seen.

"How come she can leave, but we have to stay here" Kate whispered blandly.

"I dunno" Gibbs replied and looked at her, suddenly noticing how close his face was to her.

Then he kissed her, gently at first but it quickly got ferocious as their tongues battled. Their arms wrapped around each other, pulling the other ever closer. Neither of them had actually thought about what they were doing.

Like really thought it through.

"Kate, we shouldn't do this here," Gibbs whispered as her hands went to his belt buckle.

"Ok, your place or mine" Kate's lips moved down his face to the crook of his neck.

"I really don't care, Kate," Gibbs grunted, pulling her further towards the parking lot.

"Okay, your place then" Kate was curious as to what Gibbs' house would look like because she's never been inside before, not to mention that if they went to his house, they wouldn't have to worry about the neighbors hearing, not that she was a screamer, but still.

They moved quickly to Kate's car because Gibbs' was parked right next to Abby's and she and McGee were still in the parking lot. They both got in the passenger door and Kate crawled over Gibbs to her side, her hands never leaving his body until she reached for her seat belt.

"Kate," Gibbs said as she slid the keys into the ignition. She nodded as she started the car. Kate sped off like a rocket, making it to his house in record time.

Once they shut the car off, they both scrambled out of the car and dashed for the door, bursting in as it wasn't locked. As soon as they were inside, Kate slammed the door and shoved Gibbs up against it, untying his cape from around his neck and letting it drop to the floor.

They made out there for a while, finally pulling back for air.

"Bed," Gibbs panted; he needed Kate as soon as possible, and making out in the entry of his house wasn't going to get him that.

The words didn't quite register in Kate's head as fast as Gibbs had wanted, so he picked her up and threw her over his shoulder, giving Kate a good view of his butt as he climbed the stairs.

"Gibbs," Kate squealed as his hands gripped her thighs to keep her from falling.

When they entered the bedroom Gibbs plopped her down unceremoniously on the bed and crawled on top of her. Kate wrapped her legs around Gibbs' waist, pulling him down to her and groaning as his clothed erection rubbed against her groin.

"Are you sure" Gibbs grunted, realizing that she was his agent, that they worked together, and that she was almost twenty years younger than him.

"Sure of what" Kate sighed as Gibbs' lips brushed against her jaw.

"Are you sure this, what we're doing right now, is right?" Gibbs said, slightly annoyed that he had to rephrase his question.

"No. Gibbs. It's probably not right, but it's what I want" Kate smoothed her hand down his back, untucking his shirt from his pants and unbuttoning it, pushing it down his shoulders.

Kate fought the urge to wow as she ran her hands down the toned muscles of his abdomen, knowing he would probably react the same way he had in the past.

The rest of their clothes were removed in a flurry of hurry; each piece of clothing removed came with an appreciative groan from either party.

Just after Gibbs' pants came off, he crawled back on top of her, his erection sliding against her wet folds. They both groaned in response and when Gibbs moved slightly to reach for something out of his nightstand drawer, it took Kate a little longer than normal to realize that he was reaching for a condom.

As Gibbs sat back on his heels and was about to open the small foil packet, Kate plucked it from his hands, tossing it back on the nightstand.

Gibbs looked at her in confusion.

"IUD" Kate grunted trying to pull him back down to her, "And I don't have any STDs. You?" She asked in a nonchalant way, trying not to make a deal of the fact that she'd just asked a rather awkward question.

"None," Gibbs said, allowing himself to be pulled down, resting some of his body weight on her so he could reach down and guide himself into her. Kate was glad he didn't react badly to the question because she didn't want him to stop what he was doing.

"You ready?" Gibbs asked, wanting to make sure she was ok with their current situation.

"More than ever," Kate said in such a lustful tone it almost didn't even sound like her voice anymore. And with that Gibbs slid into her, a low growl coming from deep within him.

Gibbs set a steady pace for them, slowly increasing speed as their releases came closer and closer.

Gibbs' mouth explored the entire expanse of her chest and neck, no doubt leaving marks, but both were too caught up in the moment to care.

He was unprepared when he felt Kate come undone around him, her nails painfully gripping the skin of his back, throwing him violently over the edge as well.

Soon Gibbs collapsed on top of Kate panting heavily, and only until he caught his breath did he roll off of her.

"That was…" Kate started, but Gibbs cut her off with a kiss.

"Yeah," He answered.

Kate smiled as Gibbs pulled her closer, tucking her head under his chin and tugged the blankets up over them.

"G'night, Katie" Gibbs mumbled into her hair before closing his eyes and instantly falling asleep in that patented marine way.

"Good night Gibbs" Kate yawned, dozing off in Gibbs' warm embrace.
