Elastic girl

Evelyn Deavor is not a woman who makes mistakes. Who overestimates her own magnificence, genius, and thoroughness and gets in trouble when some error she left behind screws her over.

She's not the type to underestimate others and find herself in a bind then they're far more powerful and capable than she expected.

…

Everything said above is a fucking lie.

Which is why Evelyn is currently taking the world's most stretchy dildo, AKA the Elastigirl, up her formerly tight ass. 

Maybe getting cocky and acting as if she could do whatever she wanted to her mind controlled superslave with no repercussions was an error in judgment?

Nah. She could still do that for sure….

…But maybe believing that an elastic heroine with a hypnosis-addled mind would see her displayed ass, hear "I want you inside of me.", and immediately think "She wants me to fuck her." was silly of her. 

Either way she's now in a very interesting bind where her sizable ass is being invaded and she can't speak the command to stop because-

It feels so fucking good.

…Evelyn always knew her inner anal freak would get her in trouble some day.

Sqlrch!

"OGH FUCK-!"

She just didn't expect it to be in this fashion. 

Not the heroine she used to favor the most mindlessly trying to enter her insides like they were a tunnel for her use.

Not Helen changing her approach, enlarging herself to GAPE Evelyn's asshole wider and wider. Being spread open so far by her servant isn't the fantasy the villain's had in her head since she started evildoing…

The slithering into her guts afterward only further convinces Evelyn that she needs to put a stop to this. Before it gets too extreme for her very human body to handle. Before she gets seriously hurt and can't utter the command due to incapacitation or worse…

Before she cums from the sensation of Helen's hands grabbing the spread rim of her ass and pulling it closed as she fully inserts herself in…

Too late.

The scientist is lucky she removed her clothing before trying to tease the hero into pounding her.

She might've gotten the large amount of juices she sprays out all over her pants and underwear otherwise.

"O-Oh my God. OH-!"

A corkscrew motion inside of her enlarged belly nearly drives Evelyn insane. Is Elastigirl….trying to tunnel deeper? 

Oh God.

Any deeper and she'd start going into the intestines. The only thing that's been in there is a slink, and even then it wasn't long. Her insides just weren't built for that…! It'd be impossible…but surely Helen wouldn't-

-SQUELCH deeper into her body? Already done.

Oh.

"Oh fuhck-" Evelyn couldn't stop herself from falling back if she tried. The sensations of the elastic woman within her body elongating through her guts are too much to handle and she has no other way to react than spasming in pleasure… The villain raises her hips up in the air to squirt the hardest she ever has when Helen's head finally comes to a stop inside of her stomach, juices going all the way across the room upon feeling a face press against her belly from the inside and drag its tongue over the flesh within.

One blast of cum.

Two.

Three.

Four.

Five.

It's only when Evelyn has her seventh consecutive orgasm that she's finally able to lower her hips to the floor of her lab once more, sweating all over and panting like a dog while she recovers.

Oh fuuuuuuuuuck…..

That….that could probably never be topped. Not without…

Evelyn looks down her body at her stomach.

Her wide-open mouth suddenly curls into a smile.

Not without her new sex toy.

"You….you can stay in there, on second thought. There's no reason for me to order you to come out at this point…if you can even hear me."

"I might be speaking nonsense. It's probably the high…, but you're much better like this. "

She means it too.

So much so that even after collecting herself and standing back up she keeps Helen within, sliding back into her clothing with some struggle before heading toward her private quarters.

Evelyn needed more time to accustom herself to her new slink.

Evelyn Deavor finally has the legendary Elastigirl all to herself as her obedient slave. 

Not an easy task for most…yet something her incredible prowess allowed her to do seamlessly.

If only Helen had seen through Evelyn's plan earlier….maybe she wouldn't be helpless now.

At the villain's whims.

A toy for her desires…

Evelyn smiles wickedly as she stands beside a hypno-goggled Elastigirl and lowers a hand, getting a firm squeeze of the incredible length that hid beneath that oh-so tight supersuit.

She remembers stories of the superheroine's supposedly godlike Elastidong. 

Absurdly sized. Obscenely virile. Enough to make even Mr. Incredible outclassed by a mile.

Evelyn can see it… Every single rumor is true. The monster of a shaft is hugged snuggly by Elastigirl's suit, going all the way down to her knees while somehow managing to be as thick as her pillowy thighs. 

How she managed to fight anyone with a thing like that on her, Evelyn didn't know.

What she did know is that she wanted it.

So she commands her new servant to fuck her. Definitely normal, reasonable, and not likely to backfire on her at all.

For all her smarts, Evelyn somehow doesn't do a lot of thinking when her prize is right in front of her. A bit too much ego, arrogance, and impatience…

It hadn't led to her downfall before, but now…?

She'd vastly underestimated the sheer monumental size of her Elastigirl's dick. 

The moment the supersuit is off of Helen her cock instantly doubles in size. Triples, really. Frankly, the laws of this world say that a shaft that titanic on one person should kill them….but clearly those laws were wrong.

And now Evelyn pays the price. 

Stunned into silence, Evelyn is too late to take back her command. And Helen had nothing to tell her to stop.

The fucking is brutal. 

A mind controlled Helen is a Helen with no inhibitions or care of what she does, so it's only natural that she fucks Evelyn into a cock drunk stupor. Squeezing something as large as her megadick into the villain and wrapping her elastic arms around their waist to use them as a fleshlight is somehow what comes to her mind at first, and just the action of being used as Elastigirl's personal sleeve leaves Evelyn unable to really think of a command to cease this.

When it seems like she's about to, the act of opening her mouth suggests to Helen that she's not getting enough, so soon she's being tonguefucked down her throat at the same time as her hard dicking, the foot or so Helen had shoved into her taking turns shifting around her internals like they're unimportant. 

Really, they're not.

Not to Helen, at least. The hypnosis has the fatal flaw that is not keeping Evelyn as a person of extreme importance when it comes to sexual activities. 

That means Helen fucks Evelyn until she's unconscious and keeps going far beyond that, working her oversized member into the evil woman until she herself passes out from exhaustion and dehydration.

Hours later, that is.

So the goggles needed some work???

At least a valuable lesson was learned…?
