Themes: Threesome, Rough Sex, Big Dick

Summary: Based on this image. After the Attitudinator is shattered and Ron is back to his old self, Kim assumes everything is going to go back to normal. But as it turns out, Shego has discovered she cares a lot less about being evil than she does about working for a competent boss. The former villainess is now determined to turn Ron into his hyper competent self again, even if he's no longer evil. And somehow that turns into a threesome between her, Ron, and Shego. Kim... isn't really complaining.

-x-X-x-

“W-What the hell is going on here?!”

Ron’s first instinct at hearing Kim’s scandalized voice from the doorway is to freak out. But if there’s one thing he’s been learning over these past few weeks, it’s to not give in to his first instincts. Giving into one’s impulses made one weak. So instead of freaking out, he sits there in the chair, glances down to the raven-haired woman bobbing up and down on his cock, and then back up to Kim with a raised eyebrow.

“I would think it’s pretty obvious, Kim. Shego is giving me a blowjob.”

The way his childhood best friend’s face very nearly turns the color of her hair at that does make Ron feel a little bit guilty, he has to admit. However, it’s not his fault that Kim chose to barge in here like she owned the place. As Shego had drilled into his skull many, many times, Kim did not own this Hero Hideout, as they’d taken to calling it.

Technically, it belonged to Ron. Shego had bought it for them, using stolen money. But since she’d been able to prove the money was stolen from Senior Senior, who was himself a filthy criminal, they’d ultimately let it pass. However, as soon as she’d bought the place, Shego had then turned around and put it in Ron’s name just like that.

So yeah, he owned their hideout… and Kim could have called ahead or knocked or done SOMETHING to let him know she was on her way if she didn’t want to catch an eyeful.

“S-Surely this isn’t another form of training, is it?!”

To his mild surprise, Kim doesn’t immediately turn and leave like he would have expected. Instead, she’s wringing her gloved hands in front of her as she watches Shego go down on him. It’s clear Kim doesn’t know how to react to the situation… and that’s more than fair, given how crazy their lives had gotten recently.

It had all started with the Attitudinator Incident a few weeks back. The Attitudinator was a device that was originally invented with the primary purpose of making evil people more evil. However, because of the way it was designed, it could actually make anyone good OR evil, depending on how it was used.

Over the course of a rather ridiculous stream of events, Ron had wound up as a super villain and very nearly brought the world to its knees in the process. Luckily, everything had worked out in the end and he’d been able to get back to normal, but it’d been a little touch and go there for a second for one simple reason… Evil Ron was scarily competent.

That, apparently, had drawn the attention of the woman currently bobbing up and down on his cock. With the Attitudinator destroyed, Ron and Kim had been eager to put the whole sequence of events out of their minds… but Shego hadn’t been satisfied, apparently. She’d shown up under the persona of ‘Ms. Go’ at their school mere days later and for a moment they hadn’t been sure if she’d lost her memories or what.

But no, as it turned out, she’d simply gotten a taste of what it was like to have a competent boss and decided she wasn’t going to give it up just to continue being a villain. Yep, you heard that right… somehow, Ron Stoppable had managed to turn Shego good just because of the potential of what he could become.

Or rather, back to good. As part of her convincing them that she was serious about this, Shego had reluctantly revealed her true origins… she’d literally once been a heroine, a member of a Super Hero Group called Team Go that was made up of her and her four brothers. Apparently it was their staggering incompetence and infighting that had originally turned Shego to evil in the first place.

All of this was to say, Shego had spent the last few weeks running Ron ragged. Kim had been allowed to attend the training too of course, but it was obvious Shego’s attention was mostly focused on Ron Stoppable and making him into something great. It was still a bit hard for him to wrap his head around the idea, but he couldn’t deny it made him excited.

Instead of letting Ron respond to Kim’s question, Shego finally pulls off of his cock and turns her head to look over at the red headed heroine, her eyes flashing as she grabs Ron’s dick with both hands and continues to stroke him off.

“Heh, of course not Kimmy. This isn’t training… this is a reward.”

Kim’s mouth opens and closes at that… or maybe it opens and closes because she’s finally getting a good proper look at Ron’s dick for the first time. Shego certainly seems to think that it’s the second one, because she gives Kim a wide and wicked grin.

“Like what you see? He’s pretty well hung, isn’t he? Better than most men I’ve been with. Oh, but a virgin like you wouldn’t know the difference between small and big, would you?”

Coloring, Kim scoffs and crosses her arms over her chest defensively.

“I-I don’t need to have seen very many dicks to know that thing is a monster!”

Of course, she realizes what she’s just said while sassing Shego a moment too late, her face going even brighter red and her eyes widening in disbelief at her own words. Ron has to admit, he’s a little surprised as well, staring at Kim in a new light.

“Heh… damn straight it is~”

Abruptly, Shego rises to her feet, revealing to Kim that she’s not quite dressed normally. Instead of her usual green and black, all-encompassing jumpsuit, Shego is actually wearing thigh highs and a leotard right now, showing off her thicc light green thighs and ass. Turning to face Kim entirely, Shego bends over and slips her leotard aside, spreading her thighs to reveal her glistening wet cunt.

“Go ahead boss. Take your prize~”

Ron knows that Shego is probably smirking directly at Kim as she says that, especially from the way Kim scowls. But he also can’t hold himself back. One of the other things Shego has been drilling into his head these past few weeks is that he’s more than he thinks he is. And that he shouldn’t be afraid to reach out and grab what he wants with both hands.

And sure, that sounds like it could be a little villainous, so Ron has been especially careful not to let Shego corrupt him to the Dark Side. However… there’s nothing villainous about reaching out right now and grabbing Shego by the hips as he rises to his feet and sheathes himself in her cunt in one smooth motion.

Shego moans as he fills her with his cock and over by the doorway, Kim whimpers. But the red head still doesn’t leave. After a moment, Shego reaches back, grabs him by the wrists… and takes a step forward. Ron blinks, forced to step forward as well thanks to her grip. He also thrusts even deeper into Shego as a consequence, causing her to moan even harder.

One step and thrust at a time, they walk across the room like this, all the way to a very still Kim Possible as she watches them wordlessly. Until finally, Shego is right in front of Kim, still bent over and getting fucked from behind by his big fat cock.

Then, in a sudden burst of violence, the reformed villainess lashes out, green flames ripping Kim’s top off and pulling her cargo pants down. Kim squeaks and tries to cover herself up, but Shego latches onto her, pulling her in close and giving her a wicked grin as she moans right in Kim’s face.

“Don’t try to deny it, Kimmy. We both know you want a piece of the boss.”

“H-He’s not my boss! He’s my friend! You… ugh!”

Ron tilts his head to the side, noting that Kim actually doesn’t try to deny it. Shego notices this as well, giggling as she leans in even closer.

“… Want to feel how hard your ‘friend’ is fucking me, Kimmy?”

Kim shivers, but doesn’t say no. Indeed, she does nothing to stop Shego from reaching down and slipping two gloved fingers into her exposed cunt. Wait… was Kim going commando today? She didn’t have on a bra OR panties… Ron gapes as he notices this, even as he continues to drive in and out of Shego.

Shego, of course, moans happily as she lifts one leg high into the air to give him better access, all while matching the tempo of his thrusting with her fingering of Kim’s twat. The red head gasps and moans, shuddering and shivering like she can’t get enough. Grunting, Ron grabs onto Shego’s lifted leg and decides to fuck the reformed villainess even harder.

The two women, definitely the hottest women he knows, wind up with their faces pressed together. Shego’s tongue lolls out of her mouth and her eyes go crossed. Meanwhile, Kim is shuddering, her mouth open wide as moans escape it, while her eyes are tightly closed shut like she can hardly believe she’s letting this happen.

The both of them look like they’re having a lot of fun to Ron though, especially with how Shego’s sopping wet cunt is clenching down around his cock and Kim’s pussy juices are starting to drip onto the floor.

Finally though, Ron can’t hold back any longer. He lets out a loud groan.

“Fuck! Here it comes!”

And with that, Ron unloads inside of Shego, groaning as he cums hard and fills her with his load. Shego moans wantonly while driving her fingers deeper up into Kim than ever before, which in turn causes the heroine to squeal as she bucks her hips and climaxes as well.

All three of them reach mutual release together, but the end result is a little different. For Shego, she winds up face down, ass up once Ron releases her leg and Kim yanks herself out of the reformed villain’s grasp. For Kim and Ron though, they both remain standing. His cock slowly starting to droop, Ron finds himself experiencing a bout of post nut clarity as he winces and looks over at his best friend.

“Kim, I-mmph!”

However, before he can apologize for all of this, he’s surprised by Kim literally lunging at him and glomping him! Despite her pants being around her ankles, the red head tackles him to the ground before quickly kicking the offending garment off completely. Then, she clamors up into his lap, grabbing his wrists and dragging his hands up to her waist.

“Shut up and fuck me, Ron.”

If Shego were still cognizant of her surroundings, she might have had something to say about Kim giving Ron orders. She’d certainly been doing everything she could in the past few weeks to switch their dynamic from heroine and side kick to something else. But Shego is currently out of it and Kim has a glint in her eye that both arouses and scares Ron at the same time.

As such, he doesn’t waste time in tightening his grip on Kim’s hips, lifting her up, and impaling her upon his cock. The determination on Kim’s face lasts right up until he slams her down onto his member… and then it’s replaced with wide-eyed realization and an open mouth in a silent scream as he takes her virginity and stretches her out upon his cock.

Thankfully, Shego’s intense bout of foreplay has prepared Kim for a good hard dicking, so even though there’s some discomfort from it being her first time, she’s still moaning wantonly and loudly in just a few thrusts. Then, recovering enough to properly talk to him, Kim leans forward and plants her hands on his chest, looking him in the eye.

“I l-like you, Ron.”

Blinking, Ron blushes… but thanks to Shego’s self-confidence training, he doesn’t hesitate.

“Well… I love you, Kimberly Ann Possible.”

That gets a fresh wide-eyed look from Kim, as his words seem to do critical damage to the red head. She sputters and blushes for a few seconds, squirming atop his cock in a way that has nothing to do with his large size. Finally, she whimpers.

“I hate her… b-but I love you too, Ronald Stoppable.”

Then, perhaps to hide her embarrassment or perhaps to keep him from responding, Kim leans forward and kisses him. It’s a deep, tongue-filled, hungry sort of kiss and Ron responds with all the same energy she’s giving him. And when she begins to really ride him, making her firmly toned ass cheeks collide with the tops of his legs, Ron responds in kind there as well, thrusting up into her from below nonstop.

The two of them fuck like animals more than lovebirds, truth be told. There’s nothing gentle or tender or slow about the way they smash genitals against one another. But to be fair, this had been a long time coming. Kim is Ron’s girl… and Ron is Kim’s boy. That’s how it’s always been and how it always will be, and for all that they’d toyed around with dating other people over the years, the truth was… there was nobody else but each other.

Well… each other and Shego.

“That’s it… take the boss’ cock you horny little slut.”

Having recovered, Shego is suddenly kneeling behind Kim, groping her tits and pulling Kim flush against her chest as she giggles and whispers into the heroine’s ear. Moaning and groaning in equal measure, Kim gives Shego a half-hearted scowl.

“He’s not… my boss… bitch. He’s… my boyfriend…”

Shego scoffs at that but doesn’t try to gainsay Kim again. From the look in her glittering eyes, she’s gotten what she wanted already. Or at least, she’s on her way to getting what she wants. Ron isn’t going to let her turn him into a supervillain, no matter how perfect of a henchwoman she is. But he does enjoy the training they do together… and the rewards that apparently come with it now as well.

In the end, Ron is tired of being Kim’s sidekick. He’ll take being her boyfriend instead, but on missions he still wants to start pulling his own weight. That’s where Shego is going to come in. He’ll submit himself to her harsh training methods, gain the self-confidence he needs to finally step out of Kim’s shadow… and together they’ll become the greatest crimefighting duo that this world has ever seen. Not as Kim Possible and her clumsy sidekick… but as partners. And whatever role Shego would take as well, he supposed.

They were going to be… unstoppable.
