(A/N: This story picks up at the T.U.F.F. Christmas party, which is hopefully where Kitty returns Dudley's feelings. This chapter is also the first "T.U.F.F. Puppy" (and DudleyXKitty) story I've ever written! So I'm going to start this thing before you die from the suspense.)

It was December in the city of Petropolis. In the prison, the bad guys were bemoaning the fact that Santa wouldn't bring them any presents, but ending up on Santa's naughty list was their own fault. In the city, everyone got ready for the rapidly approaching holiday, and they hadn't done anything wrong. At T.U.F.F. headquarters, there was a Christmas party going on, and this is where our story takes place.

Christmas was several days away, and the T.U.F.F. agents were having their annual Christmas party/gift exchange. (They buy presents for each other, but since they don't get to spend Christmas together, they have a gift exchange at the party.) All the T.U.F.F. agents were having a great time, and they didn't have to worry about anything bad happening anytime soon (since all the bad guys were locked up). But the following day, they wouldn't have to worry about work, because the day after the party was the start of their Christmas vacation (which they enjoyed more than the party, but not as much as Christmas itself)!

In one corner, Dudley Puppy and Kitty Katswell (she decided to attend after all) were discussing their plans for Christmas (Katrina wasn't present; she didn't feel well). Dudley cast his gaze towards the ceiling and noticed that Kitty was (she didn't even realize it) standing under the mistletoe! He knew that if someone is standing under the mistletoe, they get a kiss! Dudley was thinking that maybe he should kiss Kitty. Plus, he was in love with her, and this might be the perfect way to find out if she loved him. Then again, Kitty might get mad at him, so maybe he shouldn't kiss her. But the love he felt for her was strong, and he had difficulty fighting the urge to kiss her.

"I'll just kiss her and get it over with." he decided. Without hesitation, he wrapped his arms around Kitty.

"Dudley, what are you-" Kitty began, but that was as far as she got. Next thing she knew, Dudley was kissing her!

When Dudley broke it off, he looked at Kitty, who was grinning like an idiot. One second later, her smile turned into a scowl.

"What did you do that for?!" she yelled at Dudley (she didn't want him to know that she enjoyed the kiss).

"Look up." Dudley said, pointing towards the ceiling. Kitty looked up and saw the mistletoe.

"Is that why you kissed me?" Kitty asked, wondering why she hadn't noticed it before.

"Yeah." said Dudley.

"Why didn't you warn me?" Kitty asked.

"I wanted to surprise you!" Dudley told her.

"You didn't have to." Kitty responded.

"Wait! I noticed that you were smiling after the kiss ended. I think you liked it." Dudley said.

"I didn't." Kitty replied, but she was thinking, "Why did he have to be such a good kisser?"

"Okay, if that's how you want it, I'm gonna have to kiss you again." Dudley said with a sly grin.

"You wouldn't dare!" Kitty said, although she really wanted another kiss from him.

"Wanna bet?" Dudley asked.

"Dudley, kiss me again, and I'll-" Kitty began, but Dudley grabbed her and kissed her again.

"That does it! You're gonna get it now!" Kitty declared, trying to cover up the excitement she felt from the kiss.

"Oooh, I'm so scared! What are you gonna do to me?" Dudley teased, enjoying the whole thing.

"This." Kitty replied. She moved Dudley under the mistletoe and kissed him.

"Wow. Maybe she really did like it when I kissed her." Dudley thought. When the kiss ended, Dudley said, "Why did you do that?" Kitty smiled shyly and said, "The truth is... I actually enjoyed the kisses, and I like you more than I thought I did."

"Really?" Dudley asked, his voice 5 octaves higher than normal. Kitty nodded.

Without thinking, Dudley moved Kitty under the mistletoe again. Then he kissed her. Kitty didn't even put up a fuss, because she kissed him back. They were too busy kissing to notice that the other T.U.F.F. agents were watching them. It wasn't long before the T.U.F.F. agents (Keswick and the Chief included) started going, "Ooooooooh..."

When Kitty realized that she and Dudley were being watched, she abruptly broke off the kiss.

"Dudley..." she whispered, making him look around so he knew that they were being watched.

"Who cares?" Dudley asked.

"Point taken." Kitty replied. They went back to kissing each other until the end of the party.

When the party was over, it was obvious that they were in love, but neither of them knew how the other one felt about them.

Before starting for home, Dudley said, "Kitty, before you go, there's something I need to tell you, and I don't think I can wait until after the new year to say it."

"I also have a confession to make, but you go first." Kitty said.

"No, you go first." Dudley said.

"But I insist." Kitty said.

"Okay, if you insist. The fact that you were under the mistletoe is part of the reason why I kissed you. The other part was... I'm in love with you..." Dudley said, hoping for the best.

"There's something I should tell you, too. When I said I liked you more than I thought I did, I really meant to say... that I love you." Kitty confessed.

"You do?" Dudley asked, eyes wide with surprise.

"Yes, Dudley." Kitty said. They hugged and kissed each other once more, wishing each other a merry Christmas as they went home.

Well, what do you know! Kitty returned Dudley's feelings, and now they're an item! That's great! Stay tuned for more, 'cause this story is far from done!
