Warning: If you don't like girlxgirl pairings, then I suggest you leave now. There's nothing here that you will enjoy.

Notes: Sorry for the long delay folks. When summer came, my mind took a vacation for a while. I've also been kicking my own butt for not touching some other projects I have going, but I'm going to try and clean house in the next few weeks. So here's the next chapter, and hopefully it'll satisfy those who have been heckling me for more Kigo love scenes. So be warned, this chapter is a little steamy. Read and review!

Kigolicious Days

"Animal Instinct"

A strangled moan tore out of Kim as her eyes shot open.

The hell...?

Another involuntary moan escaped her as she squeezed her eyes shut, a bolt of pleasure burning through her body. She opened her mouth, breathing in raggedly as she raised shaky arms to push against-

Her eyes snapped open as her mind finally cleared enough to fully take in the situation.

She was naked, sweaty, and aroused to the point where trying to think was almost impossible.

And the cause for it was the dark figure hovering over her, arms braced on her shoulders, pinning her down as it grounded its hips into hers, its clothed center thrusting into hers desperately, seeking release.

Or rather more releases. By the feel of how wet the center portion of the figures sweatpants was, the other person had been quite busy while Kim was asleep.

The teen hero didn't panic. She didn't need to see who it was over her, who was basically ravaging her in her sleep. She could smell who it was. And it was all that her fast thinking mind needed to know to decide on a course of action. Usually it was her that instigated spontaneous late night sessions, but if Shego was feeling frisky, she wasn't going to complain.

The redhead wrapped her arms around the older woman's neck and pulled her down, roughly capturing her mouth as she wrapped her legs around the sweaty body on top of her.

Kim smiled in surprise when Shego whimpered girlishly into her mouth as she picked up the pace, apparently close to her peak.

Well, that was new, Kim thought briefly, moaning into Shego's mouth as she squeezed the larger woman tighter, as if trying to melt their beings into one. In all their time together as lovers, Shego had never whimpered like that during their intimate moments. She always held it back, claiming she felt it belittled her somehow.

Kim didn't pay it much mind at the time, but now that she had actually heard it, she had to say that she liked it. A lot.

When Shego tore her mouth away to take in a ragged breath, Kim shifted and quickly managed to roll them over so that she was on top. Kim laughed breathlessly when Shego whimpered and tried roll them over again, and Kim was a little surprised at the weak attempt. Usually she had quite a hard time establishing a dominant position over Shego, since the proud woman never gave it up without a struggle.

Not complaining about Shego's submissive gesture, Kim made quick work of removing her love's sweat soaked clothes while easily keeping the squirming woman in place. Tossing the last of Shego's clothes aside, Kim grinned feraly as she slipped a thigh in between Shego's before grinding into her, shuddering delightfully as she braced her hands on either side of Shego's head and established a good rhythm as she rocked into her.

The moonlight from the window of Shego's bedroom allowed Kim to finally get a good look at her face, and she stopped unknowingly when her eyes met Shego's.

Shego was panting hotly, her eyes hooded as she stared up at the younger girl. But it was the look in her eyes that paralyzed Kim.

Her eyes were completely unguarded, as if revealing her very soul to her. And in them she saw only one thing.

Lust. Desperate, mind numbing lust. Begging her to sate her mind maddening desire.

"Shego...?" Kim panted quietly, her eyes widened in shock. She had never seen such a look on her lover's face.

Shego whimpered pathetically, her hips jumping a little, trying to gain some purchase against the thigh pressed against her.

Kim felt her throat close up with want, her vision tunneling till she saw only Shego.

Kim's heart had already been beating fast due to their activities, but now it shifted gears into hyper drive as she crashed her mouth hungrily down on top of Shego's, swallowing the small sounds she was whimpering as she ground against her with renewed vigor.

She didn't know why Shego was in heat like some kind of animal, but it was driving her wild with want. Shego had always been like a wild lioness. A creature of pride and strength. To have such a powerful woman reduced to this, pleading for her touch, it was a feeling that was both foreign and addictive.

Kim tore her mouth away and hissed with pleasure as she felt sharp nails drag all the way from her shoulder blades to the hollow of her lower back.

Growling low in her throat, Kim latched her mouth onto her lover's collar bone and bit down enough to leave a mark, but not hard enough to draw blood...until she felt those nails on her lower back drag further down to bury themselves into her soft cheeks, digging into the pale skin there. Then she threw all constraint out the window and clenched her teeth around the skin she was latched onto, causing the woman under her to moan gutturally as her nails just dug in deeper.

Kim could feel an intense wave start building up inside of her, and she was just barely able to hold back the instinct to hump Shego into submission till she was satisfied. She was determined to take Shego to the edge before she followed after.

Kim tore her mouth away from the bruised skin to take in large gulps of breath as she tried to regain control, holding her hips steady as she refocused her senses.

But it seemed Shego had other thoughts as she took the moment to flip them over again, sending them toppling off the bed.

"Gah!" Kim yelped as she crashed onto her back, oofing when the larger woman landed on top of her. "Shego, you alrighmmpph!" Kim's eyes widened in surprise as Shego scrambled up her body and crushed her dark lips against hers as she roughly pulled her legs apart before doing what Kim had been trying to hold herself back from doing: humping her into submission.

Kim struggled at first as she tried to push Shego off her, but the older woman just grabbed her wrists and pinned them over her head, her larger body almost smothering her as she roughly kissed the redhead while struggling to position her aching core just right on Kim's writhing form.

Kim considered biting down on Shego's lip to stop her, but that plan flew out the window when her eyes rolled into the back of her head as Shego thrusted against her in just the right way to grind her slick heat against Kim's throbbing center. Shego moaned deeply into Kim's mouth as she began thrusting wildly, the swollen heat grinding against hers, causing the intense waves she had been holding back to reappear with a vengeance.

The teen hero tore her mouth away, breathing raggedly as she fought off the growing wave.

"Sh-Shego wait, I'm about to lose it," Kim panted pleadingly, before almost choking on her tongue when Shego latched her mouth onto her bared neck, teeth digging into the soft flesh.

Ah screw it.

Kim decided that if Shego wanted to finish things quickly then she'd go with the flow and exact some revenge after she regained her second wind. The teen managed to wrench her wrists free and wrapped her arms around her lover, pulling her flush on top of her as she held tightly, her legs wrapping securely around the woman's busily moving waist as her own hips thrusted desperately against Shego's, moaning loudly as their slick heats slid easily against each other.

"God, Shego...baby you feel so good, " Kim moaned into Shego's ear, panting heavily as she felt something akin to a tsunami building up in her.

Kim brought a hand up to push Shego's head up, needing to look into her eyes as she reached her peak.

Shego's jade green eyes were almost dark enough to be black, and the mind numbing lust in them directed solely at her was enough to push her over the edge.

Shego rested her sweaty forehead against Kim's, her hot ragged breaths mingling with Kim's as her thrusting became sporadic, signaling she was about to explode as well.

"I love you so much," Kim breathed raggedly and roughly grabbed the back of Shego's head and crushed their lips together, her eyes screwing shut as she squeezed Shego's gyrating body as tight as she could, the first waves of mind numbing pleasure enveloping her.

Kim squealed into Shego's mouth as her entire body spasmed violently, Shego's own body jerking spasmodically as the older woman moaned gutturally, her own orgasm rocking through her.

What seemed an eon later, Kim came back down to earth, breathing unevenly as she tried focus her blurred vision. She could feel Shego breathing heavily against her neck, her body lying limply on top of her.

"Holy crap Shego," Kim panted weakly, wrapping shaky arms around her sweaty lover. Kim moaned lowly as she lightly ground herself against Shego, enjoying the lingering sensations.

Kim jumped in surprise when she felt Shego's hip jerk a little against her.

"Don't move babe, a little sensitive right now," Kim chuckle breathlessly, turning her head place a chaste kiss on Shego's lips.

But the older woman had something else on her mind as she deepened the kiss, her fingers burying themselves in red locks as she slowly began moving against her lover.

Kim moaned in protest against dark lips, which quickly turned into a moan of pleasure as she held the older woman tightly against her, rolling her hips against Shego.

Kim had a feeling neither of them would be getting any sleep that night.

By the time the passed out from shear exhaustion as the dawning sun broke the horizon, neither noticed the white mist that drifted out of Shego's mouth and nose as it steadily flowed out the room and under her doorway, escaping into the cooridor of Shego's condo building...

"So what did you find out?" Ron yawned tiredly as he plopped down on Wade's bed, rubbing the sleep out of his eyes as the boy genius rolled over in his computer chair, the ruby of Inugami in his lap.

"I was up most of the night going over all these inscriptions," Wade explained. The bags forming under his eyes backed up the statement. "From what I can tell, it tells an old Japanese folk tale about a dog demon who was imprisoned in this ruby."

"Guess we can rule out the folk tale part if Kim is any indication," Ron said dryly. "So there were really demons and stuff back then?"

"Uh, I doubt it," Wade said, scrunching his face up in disbelief. "Based on the various tests I had ran on Kim, I'm guessing that when the laser beam was diffracted by the ruby, it messed with the certain elements of Kim's chromosomes, thus she's not exactly right in the head. More specifically, I'm pretty sure her higher reasoning is being cut off and making her run off of bare animal instinct. How that equates to her acting like a dog is still confusing me though..."

"But there's a possibility that there's actually a demon in there, right?" Ron said, eyeing the ruby wearily.

"Like I said, I doubt it," Wade repeated. "But I can't examine the ruby's core fully to make any conclusions. To do that I would have to crack it open, and I doubt Kim or the museum currator would be happy about that. But still, I seriously doubt something as ridiculous as demons are the cause."

"And I'm pretty sure once upon a time you doubted a lot of things before you met Kim," Ron said pointedly.

Wade blinked, looking at Ron thoughtfully.

It was true that before Kim began her crazy adventures, he never thought that gene splicing was a possibility (DNAmy), and that cloning and mind control was a thing of science fiction (Drakken). And the list just went on. Time and time again, he had to constantly reevaluate his standing on things due to Kim.

"Well, I...guess demon spirits wouldn't be too much of a stretch if we're talking about Kim here," Wade said reluctantly, eyeing the ruby. "But first, there's something I want to try out."

Ron stiffened when Wade smiled at him.

"Uh, oh, by the way, Monique couldn't make it, so maybe we could-"

"This might hurt a little bit but-"

"-wait till she's free, cause, you know-"

"-I'm ninety percent sure you'll be alright so-"

"-I'm always doing the grunt work and she hardly ever helps out-"

"-just be careful not to bite your tongue off."

"-and I think she should- wait, bite my tongue off!? Wade! Stop!"

Wade ignored him as he whipped out the laser gun out of nowhere and shot it through the ruby at Ron.
Ron felt the breath knocked out of him as he flew back and slammed into Wade's bedroom wall, feeling the entire house vibrate from the impact before slumping to the floor.

Wade tossed the ruby and the laser gun on his bed before rolling over to the blond teen.

"So, how do you feel?"

Ron blinked his eyes several times, shaking his head to clear the fog. He lifted his head before looking confusedly at the younger boy.

"I feel...fine? Huh?"

Wade tapped his chin thoughtfully, a small smile on his face.

"I thought so. You see, the X chromosomes that females have are way more complex than the X chromosomes males have. And the way Kim's genes were shifted suggested that the genes coding for behavior on both her X chromosomes were the only one's affected. And I theorized the Y male chromosome would negate the effects and thus, shooting the laser through the ruby will only affect females."

Ron stared blankly at Wade.

Wade sighed, regretting wasting a well-formed explanation on someone like Ron.

"It didn't effect you because you have testicles," Wade said bluntly.

"Oh," Ron said stupidly, shifting uncomfortably. "So...Kim?"

Wade shrugged.

"Like I said, it's only screwing with her behavior. The problem is what part of it. Everybody is wired a little different, so the effects of the ruby probably vary from person to person. While the ruby made Kim act like a dog, it might not be the same for other females. I'll have to run more tests," Wade said as he rolled over to his computer.

The Ron quirked his head curiously when Wade frowned at his screen and mumbled something under his breath.

"Uh, Wade?"

The boy genius shook his head, turning towards Ron.

"There's been a sudden flood of police reports coming out of Upperton concerning strange behavior among some of the residents."

Ron's brow furrowed as he realized the coincidense.

"Well, Kim's in Upperton with Shego right? You don't think..."

Wade shook his head.

"We both know Shego has her on lockdown. But just in case, I'll give her a call and check up on them," Wade said as he turned back to his computer."

"Uh, wait dude. You seriously calling her now?" Ron asked dryly, tapping his watch.

Wade blinked at him, and winced as he recalled the last time he called up Shego fairly early in the morning and woke her up. His ears hadn't stopped ringing for that entire day.

"Right, let's wait till the afternoon. I mean, how bad could it be up there?" Wade reasoned, Ron nodding his head sagely.

"Good lord," the 911 operator muttered as he disconnected his precious caller.

"Another one?" asked a colleague, who looked just as tired and haggard as his friend.

"Yeah, this time someone is complaining that a group of old ladies are chasing the mail man down the street and barking at him like animals," the operator said incredulously as he prepared to call in the report to the patrol units.

"Christ, was there a break out at the insane asylum or something?" the other operator muttered as he connected an incoming call.

"Help, my husband just ran out the house with no clothes on and is barking like a dog!!" a high pitched voice screached.

The operator pinched the bridge of his nose as he sighed heavily.

"Trust me lady, he's not the only one," he muttered as he began trying to calm the hesterical woman down.

Kim groaned tiredly as bloodshot eyes cracked open, her dull olive green eyes staring blankly up at Shego's ceiling, squinting from the sunlight that was hitting her eyes.

She shifted her body just a little bit and winced as she felt various parts of her body protest.

One would think she would be concerned from a bodily signal that was supposed to indicate bodily injury, but one would be wrong in this case.

The previous night's activities came rushing back as she became fully aware of her aching body.

The teen hero blinked several times before a goofy smile slowly spread across her face.

"Wow," Kim whispered, wincing when she realized the inside of her bottom lip was cut.

When she did realize this, her grin got bigger.

She glanced over her shoulder where Shego was spooning her from behind. The redhead made a note to tease her lover about about the bit of drool leaking out of her mouth.

Kim carefully rolled the older woman onto her other side before curling her own body around the pale green one, her face buried snugly in her thick locks of hair and her arms tucked under Shego's, her arms wrapping over the woman's bare breasts.

Not that she didn't enjoy being the one to be on the receiving end of their spooning sessions, but she preferred to be the one doing the spooning. It gave her the symbolic feeling that Shego was trapped in the embrace of her love for her, and the only way the older woman could leave her was if she ever let go of those feelings. It was corny and sappy to the fullest extent, and thus the main reason she never told Shego her thoughts about it. She was teased enough as it was.

The petite redhead lazily hooked a leg over Shego's waist, sighing in contentment when her slightly sore center pressed against the soft, smooth skin of her lover's posterior. That was reason number two for preferring to be the spooner. Her lover had one hell of a behind.

The teen hero considered waking Shego up, since she couldn't remember whether the former thief-turned-agent had work today.

What day is today? Kim suddenly thought, her brow furrowed. She tried to recall what she did the previous day. She remembered her and Ron on security detail at the museum, some thieves breaking in, and then.....

Her brow furrowed even more. It wasn't that she couldn't recall anything, but it was all like a chaotic collage of snippets of memory.

She remembered at one point her being really excited as someone chased her for some reason. She also recalled being overwhelmed with feelings of shame and fear as Wade's mom yelled at her...for some reason. And she also recalled being deathly afraid as she ran away from Shego....yet again, for some reason she couldn't recall.

"Was I drugged or something?" Kim muttered, frustrated and worried that she couldn't recall anything concrete. She blinked when she heard a soft moan as Shego hugged Kim's arm tighter around her, squeezing the limb more tightly around her chest. The redhead blinked again when she felt hard nubs press into her forearm

All thoughts about the previous day flew out the window as Kim felt a goofy smile cross her face. The gears in her head were spinning quickly as she considered her next actions. If she played her cards right, she was pretty sure she could coax Shego into doing a replay of last night.

She brushed back Shego's silky black hair to place soft kisses to the nape of her neck, gently cupping one of her lover's tantalizing mounds before kneading it firmly. She couldn't help but moan quietly herself from how wonderful her lover felt.

She began lightly suckling the exposed neck, pulling back the leg hooked over Shego before carefully nudging it snugly between Shego's legs and pressing it firmly against the sleeping woman's core.

"Shego," Kim moaned quietly, closing her eyes as she pressed her forehead against Shego's neck, taking in a shaky breath as she took a moment to just enjoy the hot flesh searing against her thigh. She had to hold back the instinct to just flip the older woman over and ravage her...although that was basically what Shego had done last night.

Shego groaned groggily as her eyes cracked open, her breath hitching when Kim began rolling a nipple between her fingers.

"Kimmie?" Shego croaked out, trying to roll over to look at Kim, but the redhead held fast. "Hey, what-"

"Shush," Kim said softly, before pressing her lips against her lover's ear, kissing it lovingly. "Just enjoy it."

Shego sighed contentedly as she rubbed the arm Kim had wrapped around her, squeezing her thighs together around the thigh Kim had between hers. She froze when she realized something.

"Pumpkin, why the hell do I feel like I was just plowed by a freaking fire pole?" Shego asked groggily, wondering why certain regions of her body felt so sore.

Kim chuckled, pressing another kiss against her ear.

"Are you kidding? After last night, I'm pretty sure I'll be walking funny for a week." Kim kissed her ear again holding it there a little longer. "You were amazing. And uh, I don't mind the, you know, that one thing you did last night. It was kind of kinky, but I...kind of liked it actually," Kim admitted shyly, feeling her face flush heavily as she remembered a certain part of last night.

Shego frowned deeply, confusion written all over her face.

"...What the hell are you talking about?"

"There's no need to be embarrassed, you didn't see me complaining last night, right? You can touch me in whatever way you want," Kim comforted, sitting up a bit to hook a finger under Shego's chin, turning her head to lean down for a kiss.

She blinked confusedly when Shego pulled away and glared at her.

"And I'm telling you I don't know what the hell you're talking about," Shego said firmly. Her frown deepened. "And what do you mean last night? What happened....last...night..."

Kim stared worriedly down at her lover as Shego's eyes became impossibly wide. The teen hero yelped when Shego suddenly spun around and pinned her down to the bed, her hands firmly pressed against her shoulders.

"Kimmie...you're back to normal!" Shego said incredulously, a smile starting to spread across her face.

"Shego...what the hell are you talking about?" Kim asked her, looking at the older woman as if she was insane.

Shego laughed happily and bent down to kiss Kim thoroughly before pulling back to smile down at Kim's dazed face, a wide smile on her lips.

"Okay, I'm not going to complain about that. But I still don't know what you're talking about."

"I'll explain later, since I'm sure you don't remember anything about yesterday," Shego murmured, bending down to kiss Kim again. She was just glad to have her normal lover back.

"Yeah, I don't," Kim murmured against dark lips. "But I do remember last night at least."

Shego frowned and sat up, staring down at the smiling teen.

"What happened last night?" Shego asked carefully, racking her brain for what she could remember. She remembered going to sleep, and then having some freaky dream. She couldn't remember what it was about, but she could remember that it was something like she had a horrible itch that she couldn't relieve herself of no matter what, and it nearly drove her insane.

A moment of silence passed as the two lovers stared at each other.

"...Huh," Kim said thoughtfully. "That's weird. I can't remember what happened most of yesterday, but I remember last night..."

"...And I remember most of yesterday, but not last night," Shego finished. "...Goddammit."

With an irritated sigh, Shego rolled off the petite teen and scooted out of the bed.

"Hey, you can't just kiss me like that and walk away. I'm hurting for ya here," Kim whined, rolling onto her stomach and trying to grab her departing lover.

Shego dodged the searching hand, quirking an eyebrow at the pouting teen.

"And I'm hurting literally. What the hell did you do to me last night?" Shego asked incredulously, shifting uncomfortably, trying to get use to the soreness.

A perverted smile crossed Kim's face as she chuckled lowly.

"Everything," Kim said sleazily.

Shego took a moment to just stare blankly at her young lover.

"You know, I think I liked you better when you were all innocent and pure," Shego deadpanned, glaring at the smirking redhead.

"It's not my fault you corrupted me," Kim said casually, propping her chin up on her hands, her smirk widening as she let her eyes rake up and down her lover's naked body, admiring the marks from their nocturnal activities.

Shego rolled her eyes, stiffening when they landed on her bedside clock.

"So much for work," the agent sighed, walking towards the bathroom connected to her bedroom.

Kim giggled to herself as she rolled onto her back, sprawled out on the bed.

"I'm guessing we should visit Wade and see if he can fill in the blanks for us," Kim called out, stretching her body and sighing as she relaxed.

"Might as well. Give nerdlinger a call," Shego responded back just as the sound of the shower running started.

Kim turned her head to blink at the open bathroom door. A happy smile spread across her face as she began scrambling out of bed.

"If you step one foot in here, I swear I won't let you lay a finger on me till Christmas," Shego growled out, causing Kim to freeze just as she was stepping off the bed.

The redhead was stone still as she thought over the threat, weighed the possibilities, estimated the length of time Shego would most likely hold out on her, factored in how fast she thought she could break her lover down, and smirked confidently as she jumped off the bed and dashed into the bathroom, slamming the door shut behind her.

A heavy sigh sounded out.

"Goddammit Kimmie....."

A giggle was all that responded.

Those were the last intelligible words spoken for the duration of the shower.

Betty glanced up from the paper she was reading as Will Du opened her office door.

"Intelligence says those twins had a bit of a scuffle with Jack Hench," Will said as he dropped another report on the one-eyed woman's desk.

Betty blinked at the report.

"Interesting," she mumbled before turning back to the paper she was reading. "I just received word from one of my sources. He didn't give me much, but he gave me something to follow up on."

Will glanced down as Betty slid the paper over to him.

"Project Intruder?" Will mumbled.

"My source says it keeps coming up whenever Diana and Leda are mentioned, doesn't know what it is though." Dr. Director glanced up at him. "Look into it."

Snapping off a salute, Will took the paper and left her office.

Betty leaned back in her chair and steepled her fingers as she glanced down at the report Will had left.

A small smile crossed her face.

"Well Shego, it's time to put the criminal record of yours to use."

to be continued...
