Looking upon their sister Diana and Koriand’r watched as Karen began to grow, swelling larger and fatter by the second while a bright red glow emanated from her rounding belly. The subtle crunch of growing bones and muscle creaked away inside the massive creature, nearly doubling in size all over again before rolling onto her back and arching her back to give room to her ten swelling breasts. Energy… So much energy... Rolling her shoulders Karen felt her neck grow longer, thicker, even her tail began to fatten making her look like some kind of massive leviathan or whale. Now over a mile long Karen howled a deep low moan, her many claws tweaking her dripping breasts in a frenzy just as she looked to her smaller sisters in a pleasure drunk stupor.
Consuming Captain Atom had allowed her alien biology to radically adapt to the dangerous radiation; leeching it, catalyzing it to fuel her growth to unseen levels. Yet she had much more to spare. Hefting up the bulk of her upper pair of breasts she aimed them at Diana and Kori, squinting her eyes as the rush of energy still coursed through her.
Drink…
Seeing their sister swell up larger like a balloon the two hesitated, as big as they were they were merely a third Karen’s size now and she continued to grow.
DRINK! NOW, while I can still offer such power!
Needing no other invitation the two matriarchs descended on their sister, snapping their fanged lips onto her breasts and pulling in great pulls of energy saturated milk. From there the intense heat began to dim in Karen, flowing out of her into the two at her chest with each starving gulp. Catching herself with her growth slowing Power Girl smiled watching her sisters swell and grow, catching up to her in size and bulk. In seconds Diana grow larger, her neck and tail gaining mass along with the rest of her until she looked as full bodied as an orca, pressing up against Koriand’r the two started competing for space above their new source of nourishment. Starfire’s mind was awash with bliss, the orange glow in her flesh shining brighter as the sea of tentacles lining down her head and back squirmed with activity. So much POWER! Like swallowing the sun…
When the heat finally died down for all three of them the matriarchs pulled away briefly to look at themselves. Massive beyond measure the three were each over a mile long, their six claws wide enough to encompass a street along with rows of breasts larger than a house. Still entwined with each other the three leviathans purred at their new size, their tails coiling up together as their large claws began to get caught with one another.
So massive sister, so perfect…
Yes… Perfect, unstoppable…
Rolling her eyes back and bearing her exposed neck Karen let Diana and Kori like up her chin, pecking at her scaly flesh with pert lips all while claws groped and caressed at far larger curves. Their city block wide hips ground against each other, legs getting crossed with one another as the three lost themselves in each other. With a smirk Power Girl arched her thick tail and aimed it straight into Kori’s gushing opening, making the leviathan moan with excitement from the intrusion. Bitch. Smirking back at her sister lover Koriand’r extended her hair to wrap around Karen’s many breasts, squeezing and coiling around their bulky curves with greater dexterity than fingers ever could. Smiling at the idea Diana used her own tail to pierce into Power Girl, laughing at the former blonde yowling in orgasm from the over stimulation. Wanton Slut.
Hush you two, so catty…
Arching her head down to kiss the former amazon princess, their tongues coiled and snaked together just as their lips met, pulling away only briefly to change partners.
With what little resistance left destroyed and ruined the matriarch’s species now had full reign over the planet, but for now they wanted to savour this moment, they weren’t hungry just yet after all. And the night is still young.
