XS becomes XSessive!

Nora staggered back and fell to the ground, sputtering out as much of the mother's milk as she could from her mouth after being drenched in the fluid. But even then it was already too late. She could hear her heart boom in her chest and ears and her muscles tense like rope becoming taut. Gasping for air and clutching at her head, she could already feel her clothes becoming tight and uncomfortable. Clutching at her costume, she could already feel the tightness become constrictive around her chest and hips.

"Think of it Nora, Mother and daughter together making our tribe big and strong." Iris purred, watching the human woman rip open the front of her costume just so she could breath, freeing her growing breasts which already passed DDD size as the rest of her grew out of her clothes. "You can FEEL it can you? The power, the drive, the freedom! Together we can grow and multiply and live consequence free, a tribe of thousands that will be seen for miles around."

Moaning as she clutched at her exposed breasts and down at her thighs as they burst open her pant legs, Nora's eyes fluttered as another voice began to scratch and claw its way out of her inner psyche. Moaning whorishly, and blasting her mind with images. Images of her being huge, not only in height but in strength and feminine bounty. Hips so wide they rivalled the size of a house! Along with her meaty rear that could easily be compared to one. Breasts bigger than tanker trucks and just as full of rich mother's milk. And for good reason. Her mind raced with images of her increasingly pregnant, bearing twins, triplets. All the while she was surrounded by a growing tribe of muscular, hairy cave people as far as she could see.

It was all too much to hold back. And in that moment of being beaten down by her base self, said base self finally spoke up when it stood over 70 feet tall and plucked away the shreds of her costume that clung to her like bits of string.

"BIG NORA WANT COCK!"

Smiling and pulling the new giantess close, Iris leered back at the wild eyed giantess as they wrapped their arms around each other and kissed hungrily into each other's lips. Their massive breasts mashed together and threatening to touch their chins as their hands felt up their thighs and asses. Not wanting to be out on the fun, Iris let her wild side take hold, just for the fun of it.

"BIG NORA WANT COCK!!!"

"BIG IRIS WANT COCK! MORE COCK THAN NEW SLUT IN TRIBE!"

"WHERE COCK?" Growled the fledgling giantess, her hair wild and unkempt after it overgrew and spilt over her her shoulders and down her back. "YOU NO KEEP BIG NORA FROM COCK!"

"COME WITH BIG IRIS! BIG IRIS SHOW YOU WHERE COCK IS. EVEN HAVE MORE THAN YOU!"

Distracted from the screams overhead, Iris and Nora took to the air and flew back to the clearing where the tribe slep.
