Kim spent three hours being social during her parents' new year's eve party, meeting and greeting their coworkers. Too many conversations were little more than platitudes about home, school and her plans for the future. She couldn't blame Ron for skipping out early; she'd even joked about taking her with him. At least he seemed disappointed by the fact that they were parting company before ringing in the new year, but since he'd started spending Christmas with the Possibles, he always spent new year with his own family to balance things out.

Noone brought up her heroic hobby. It actually left her feeling a bit insecure. Did her parents never talk to any of their friends about it? They always said they were proud of her for it, but...

By the time midnight was approaching, Kim had lost the party spirit, so she excused herself from the ongoing celebrations and retreated to her bedroom. Once she was there, she decided she wouldn't be going back down and started changing for bed.

When she opened her closet, Shego jumped out at her, arms raised, with a loud, "HA!"

Kim's reaction would have sent her toppling backwards into - or through - the dressing screen, so the villainess jumped forward again and caught her as she lost her balance. With Shego's arms around Kim's back and waist, and Kim's hands grasping onto Shego's shoulders, they both froze as they realised a particular aspect of their situation.

"Why, Kimmie," Shego stated with a grin that would put the Cheshire Cat to shame, "I do believe you're topless."

The teenager quickly transferred her hands to her own shoulders so that the objects of Shego's attention were covered. "Are you crazy? What if someone heard-"

"With all the noise downstairs? I wasn't about to waste the opportunity... though I must admit, I wasn't expecting a bonus..."

"Let me up," Kim demanded, blushing profusely. To her surprise, Shego complied, immediately and without complaint. The smirk on her face remained, however. "You're evil," the teenager complained, turning away from the green girl.

"Don't slouch, stand straight."

"What?"

"If you're going to deprive me of the view of your front, you better make the view of your back worthwhile."

Hesitantly, Kim straightened her posture, pulling her shoulders back until she heard a satisfied hum from behind her. A hand pulled her hair to one side and over a shoulder, then travelled back to her neck. She could feel the tips of Shego's claws barely gracing her skin as the hand travelled down her spine. When it reached the small of her back, both clawed gloves took a gentle hold of her hips. She almost turned as Shego's face entered her peripheral vision, but it was only to whisper in her ear, "Stay still."

Kim felt Shego's lips on her skin a moment later, but not to kiss. Instead, they travelled the same path her hand had done down her spine, hot breath causing goosebumps all the way down. Again, the villainess reached the small of her back; this time, she made the redhead gasp as she explored the curve with her tongue, before breathing her way back up to Kim's neck.

The heroine was rooted to the spot by how her body was reacting. "W-what was that?" she breathed.

"Fun," Shego informed her as she stepped forward and wrapped her arms around the smaller girl's waist. "Was it fun for you?" Kim could only gulp nervously in response. Shego chuckled, even as she looked down over the shivering girl's shoulder. "Still insecure about your cup size?" With Shego's breasts pressing against her back, Kim could hardly contest the notion. The green girl nipped gently at an ear before whispering into it, "Would it help if I told you I want to touch them? Taste them?"

"...Do you?" Kim dared to ask.

Shego made a show of extending her forearms and pulling her gloves off, a finger at a time. Once both had been dropped to the floor, her fingertips traced the contours of Kim's stomach until her palms were flat against the curve between stomach and ribcage. Slowly, she slid her hands upward, and the redhead's arms loosened to allow them passage. It was no small joy to see her nipples looked hard enough to cut glass, but Shego avoided them at first, cupping and exploring the surrounding flesh.

Abandoning herself to the sensations Shego was causing in her, Kim leaned back and eased her head onto the older girl's shoulder. Her weak knees made it seem that Shego's hands and breasts were all that were holding her up, and she was loving it. She lost track of time before twin fingertips finally passed over her nipples, forcing a shuddering gasp through her. The pinching that followed had her biting her lip to keep from moaning aloud.

"I believe I have something to show you," Shego's husky voice informed her.

It took a moment for Kim to make the connection, and the twin sensations of arousal and rattled nerves coursed through her. This isn't right, it... it feels so good, how can it feel so... it's wrong. She's... a she, and an enemy, and... oh god... and it all might be an elaborate plan... what would I do if she showed me... she'd get in so much trouble if we were caught...

Shego's ministrations were interrupted when the girl in her hands suddenly started giggling like a madwoman. "Uh, what's the joke?" she asked, wondering if she should be offended or simply disturbed by Kim's behaviour.

"Sorry... sorry. It's just..." Kim regained her equilibrium enough to stand upright, and she turned back to Shego. "I had a thought. That you'd be in trouble if someone saw..." She couldn't even finish as voicing the thought caused a fresh bout of giggling.

The villainess rolled her eyes. "Yeah, that would be a bit redundant, wouldn't it. Have you been drinking?"

"Just a glass of white wine. I didn't even finish it. Things downstairs were a little..."

"Stale, I bet," Shego guessed as she watched the redhead's mood sober. "Your parents will let you go off on dangerous adventures, but they won't let you find a decent party on new year's eve." She took a final look down - Kim hadn't tried to cover herself again when she turned around - then decided with a grin, "I'll let you finish getting changed."

Kim felt a momentary panic as Shego left her view, thinking she intended to leave; it passed as she heard the bedsprings complain as the green girl threw herself upon them. Then another bout of panic as she considered the possibility of Shego undressing, to fulfill her part of their bargain. She listened, but zipper noises were not forthcoming. The only sound that wasn't coming from downstairs seemed to be her own vibrating body.

The teenager looked down at herself, surprised by such a notion, but it felt accurate. If she didn't know better, she'd have sworn her body was begging for more. She tried to mentally quash her hormones or libido or whatever else as she finished getting changed into her sleepwear.

When she emerged from behind the screen, Shego was lying across the window side of the bed, in a position that showed off her curves. "That definitely wasn't about fighting," Kim scolded her.

"We didn't really do much fighting last week, did we?"

"The whole thing did turn out ferociously wierd..."

Shego watched the teenager eye the bed with apprehension until she reached over to pull back the far corner of the duvet. "You get in, I'll stay out," she suggested.

Kim gratefully slid under the covers, which Shego folded back into place once she'd settled. "I did notice that your blasts didn't even damage Snowman Hank," the teen hero mentioned.

"What can I say, it was Christmas."

"You never struck me as the religious type."

"I'm not. I'm the vacationing type." Shego sighed wryly. "I was toasting on the beach before Dr. D called for me to rescue him. Woulda scored a nice big bonus for it too, if he hadn't already paid for the holiday."

"That was generous of him."

The green girl shrugged. "He remembers to appreciate me on his good days."

Kim snorted. "Good days."

"Yeah, yeah." Shego watched the redhead for a moment. "So, are we going to pretend I didn't just feel you up?"

"I was considering it," Kim nervously admitted.

"Because I got the impression you were loving it," the villainess remarked, then smirked at the resulting blush. "Do you want to see what I owe you?"

"Um." Kim's eyes automatically shifted to Shego's crotch, and she chewed her lip as she considered succumbing to her curiosity. In the end, however, her nerves won out. "Not yet. If that's okay..."

Shego simply shrugged. "Up to you. The upside of not getting out of the suit is that I don't have to get back into it."

"Why do you wear it?"

"It suits me." Kim rolled her eyes at the pun before Shego continued. "It suited you too. I noticed you still have it in the closet."

"Oh! You can take it back if you-"

"Keep it. I've still got your mission outfit, anyway."

"Oh, yeah." Kim thought about that a moment, then asked, "Did you ever... try it on?"

"Just the top," the villainess admitted. She certainly wasn't going to share the fact that she'd only tried it on after her last visit, nor that she'd held it to her face and inhaled as deeply as possible beforehand.

"What's wrong with the pants?" the teenager asked, slightly miffed.

"Olive? Bleh. Too drab for me." And loose pants aren't sexy. "Maybe next time we tussle, I'll wear the crop top and distract you with my bare midriff... and if any accidents happen, so be it."

"Accidents?"

Shego grinned lasciviously. "The fabric was straining to contain me. I wouldn't be surprised if something ripped while we were at it." She grinned as the teenager blushed anew. "You walked right into that one, cupcake."

A countdown from ten from the crowd downstairs. The girls looked in the direction of the stairs, then back to each other.

"Hey, princess," Shego drawled.

Kim knew what was coming and smiled beautifully. "Yes?"

"Happy new year," the villainess said in time with the cheer downstairs, before leaning over and kissing the heroine. It was surprisingly chaste; her tongue only got involved once she'd broken the kiss, a playful flick at Kim's lips before she drew away again.

"Shego?"

"Yeah?"

"Don't I have to kiss you, now?"

"I don't think that's how it works, cupcake."

"I'm willing to bend the rules if you are," Kim told her, pulling her back down and licking Shego's black lips before starting a kiss that quickly turned passionate. Their tongues met, and the contest between them began.

They were still making out when Ann, halfway up the stairs, saw what was going on and nearly dropped the glasses of champagne she was carrying. She stood staring, mouth agape, for a long moment before retreating back downstairs to collect her thoughts. The duvet had been between them and all hands were accounted for, so that was something, but...

"Kimmie, are you still up?" she called up.

There was a significant pause, but Ann heard nothing before her daughter's voice responded, "Pretty much."

Entering the bedroom, there was no sign of Shego. Ann's eyes went to the closet, then the window, (both of which were closed) before focusing on Kim. "I thought you might have had enough of the party tonight; it's not exactly your scene, is it? I didn't want you to be alone at midnight, so I thought we could toast the new year." She held up the champagne.

"Oh. Um, okay," Kim answered, obviously trying to appear nonchalant, in contrast to the heated state of her face.

"Are you okay, Kimmie?" Ann asked as she sat on the edge of the bed and offered her daughter a glass.

"Yeah... it's just... the white wine made me a little... flushed."

Her mother leapt on the opportunity. "Well, I don't mind if you experiment... just to see what you like or not..." she watched Kim's blush deepen before offering her a soft smile. "So I don't mind a glass of something or other, every once in a great while. While we're around," she added emphatically. "We wouldn't want you to go overboard with anything. Remember, you're not even of a legal age, yet."

Kim nodded in agreement, so Ann held her glass and let her daughter tap it with her own.

"Happy new year, Kim."

"Happy new year, mom."

They both drank, and Ann watched as her little girl rolled the taste of the champagne around her tongue before swallowing. She chuckled softly at her line of thought, but she answered Kim's querying eyebrows. "My little girl is growing up," she said, sounding both pleased and proud.

"Just don't tell dad," Kim asked with a smirk.

"I won't." Ann stood and made a point of not collecting Kim's glass before heading back down the stairs. "Sleep tight."

A moment later, Shego slipped back out of the closet, pulling her gloves back on as she peeked down the stairs. "She knows," she decided as she sat where Ann had just been, and relieved the teenager of the glass she was holding.

"How can she?" Kim asked, equal parts incredulous and horrified.

"She's your mother," was the green girl's only explanation after taking a swig of the champagne. Then she grinned. "Must say, though... I hadn't noticed during Christmas, but listening to her just now... she has a hell of a sexy voice."

Aghast was the only word to describe Kim's face. She couldn't even manage a sputtered exclamation of horror and outrage. Shego had to restrain herself from laughing out loud, instead sniggering into the glass before taking another sip. Then, after putting the glass on the bedside table, she slid over and gave the the teenager a last, flavoured kiss.

"G'night, princess."

Kim watched silently as Shego's hips swayed over to and out the window.

Standing below and behind the stairs, Ann nodded approvingly as Kim's bedroom light went out. Obviously the relationship between her daughter and Shego was more complicated than she had ever imagined. She'd be paying a lot more attention to what went on upstairs, from now on.
