Marvel and DC: Kara, Carol, and Karen are the first to change

Patrolling the space around earth Carol Danvers is joined by both Supergirl and Powergirl, to see if any unfortunate aliens ended up crashing out here. Examining a debris field from an old battle Carol wonders just how many aliens they've fought off over the years. Still, that's why they're out here making sure there aren't any remaining threats and that things are as they should be.

"Hey guys I think I found something." Supergirl says getting the attention of the other two.

"Really what is it?" Powergirl asks.

"I'm not sure it might be distress call or just a message caught on a loop." Supergirl replies.

"Can you two pinpoint it since I don't have super senses like you guys." Carol asks the pair of Kryptonian ladies.

"Sure, thing I've picked it up now. Follow me." Powergirl adds.

Leading the other two to a wreckage with what seems to be minimal power but enough to still have an atmosphere and minimal gravity. Collecting the wreckage, the trio bring it aboard a Javelin so they can more closely examine it. Opening the hatch, they find a console broadcasting a near unidentifiable message with an odd recurring popping sound. Fiddling with some technology the only thing they manage to clear up is the POP making it loud and clear.

"What is that sound? It feels familiar but I can't place it." Supergirl comments.

"Yeah, me too. Carol, what about you?" Powergirl asks.

"I don't know I think I need to hear it a couple more times." Carol replies.

Listening to that wet loud smacking POP again, Carol feels a strange sensation as she's starting to get horny. Looking over at Kara and Karen they seem to be in a similar situation. Another POP and Carol feels a strange swelling in her womb, unaware to Carol her eggs are exploding into highly aggressive sperm. Attacking and destroying more and more eggs and generating more sperm. More POPs and Carol needs to push and get rid of the wrongness of having a vagina. With a final push Carol's destroyed womb falls into a pair of heavy balls with a resounding POP. Her no HIS clit has grown into a sizeable foot long cock any true man like himself would be proud of. Looking down Carol is surprised by the sheer size of his chest his tits have seriously grown they must be bigger than Powerbro's. Snapping him out of his reverie is the sound of another pair POPs of cunt destroying music reaches his ears.

"Damn Powerbro and Superdude those are some pretty nice cocks." Carol admits.

"Thanks man. Is it just me or do I seriously need to blow a load right now." Powerbro admits.

"Like totally my cawk is just so hard right now." Superdude says sounding like a bimbo though a manly one.

Grunting in agreement the trio grabs their cocks and start pumping, soon enough the trios rock hard cock blast out stream after after stream of thick ropey cum. Giving each other high fives and breast bumps just like dudes.

"Oh, gross those are like all those icky eggs we used to have." Superdude notices using his supervision.

"Wouldn't use Kara's words but he's got a point that's pretty gross. So, what should we do about them?" Karen asks.

"Well, you both got heat vision unless you want me to blast them." Carol suggests charging up a photon blast.

Both Krytonian Bustybois grin as they fire their heat vision though not enough to damage the floor. Using their super-hearing they can hear what used to be their eggs boil and pop destroying the last trace of their pathetic femininity.

"Come on guys let's head back to earth I think we're done here." Carol tells the other two.

"Oh, wait I want to like add these totes awesome POP sounds to my phone." Kara says excitedly.

Carol and Karen roll their eyes at Kara's antics though they do wonder where the bimbo like Bustyboi. They do briefly wonder where he was hiding his cell phone, then again, he always keeps his phone within reach to update his numerous socials. Recording the POP and adding it to his favs maybe he could get someone good with tech to mix the POP into some songs he likes. Strapping into their seats the Javelin rockets towards earth bringing with it a change no one could ever imagine.
