Caitlin threw her head back, mauling her massive breasts as she rose up and down, up and down, Barry’s member sliding into her red hot snatch and hitting places that would have had her brainless even if she weren’t embracing her savage side. The doctor arched her back, her forehead pressing against the ceiling as she felt herself swelling larger with every plunge down onto Barry’s monstrous dick. Even more wonderful was the feeling of him growing inside of her, his cock thickening and lengthening as it slide deeper and deeper into her needy snatch.
To her side she could see Felicity rocking against Iris, the blonde who’d started this latest round of fucking rubbing her pussy and breasts against Iris. The black woman didn’t seem to mind, mewling like a cat in heat as Felicity showed that Barry wasn’t the only one to like her curves. For a second Caitlin’s own moans are overshadowed by Iris’ pleasure-filled cries when Felicity begins to finger her ass.
Letting out a gasp as her first orgasm builds closer and closer Caitlin reaches out, reveling in just how big they’ve gotten. Barry can’t even lie stretched out without his feet smashing the wall and Caitlin is forced to duck her head as her back pressing against the ceiling. Felicity and Iris manage to get ahold of themselves long enough to begin destroying all the tables and counters to make room for their own bodies but even then it isn’t enough and soon they have tumbled on top of the two with Felicity’s ass landing on Barry’s face while Caitlin gets a wonderful look at Iris’ tits.
For the briefest of moments the savage woman pauses and considers what will happen if she grows even an inch more. The largest room in Star Labs was the cafeteria and they have nearly outgrown it. A few more inches and the walls will come down and even that space will no longer be an option. More than that, Caitlin dimly realizes that any chance of undoing what is happening to them will be lost if this continues. If Star Labs falls she doesn’t know if anyplace else in the world will be able to help them. They will be like this… forever.
Caitlin looks down at Barry and rises up, keeping only the tip of his cock in her pussy. The massive savage looks at her in confusion, as do Iris and Felicity and Caitlin takes a breath…
…before plunging down on Barry’s cock.
She rides him harder, her mind exploding as she truly let’s go. The growth begins again and Caitlin welcomes it and her savage side, holding them close. In her mind she sees what they will become. She sees herself lying not in Star Labs but upon it like it was a bean bag chair, her body so large that it stretches for blocks. Beside her Felicity and Iris lounge as they watch Barry stomp through the town like a kaiju, his massive hairy body calling to them to join him. She sees herself rising up, her body bloated with massive curves and muscles, limbs hairy and her hair a tangled mess as she thunders towards him like a cavewoman before letting him take her in the middle of downtown, her massive breasts destroying her apartment building as he fucks her hard.
Caitlin sees this all and embraces it, welcome it. She is Big. She is Savage. She is Barry’s as he is Her’s. The world be damned… all that matters is fucking and growing.
She screams as Barry cums in her, her head smashing through the ceiling as Barry and Felicity’s feet destroy one wall and Iris takes out another with her massive ass.
Fuck and grow.
Fuck and grow.
~BIG~BIG~BIG~Hours later Barry slowly opened his eyes, staring up at the destroyed ceiling to the night sky above. He shifts, the entire building trembling as he does so. Felicity, Caitlin, and Iris are all cuddling with him, their massive frames the only things holding the building up. "Uh no," Barry moans as he comes back to his senses as he begins to gently wake the girls up.
