“Sis…”

Rebecca gasped at the sound of her brother’s voice from behind her. She tried to stand up, but a heavy weight on her chest inhibited her movement. Looking down, she was shocked to see her breast had almost doubled in size. She had gone from an A to a D! She also noticed that her thighs, hips, and butt were also plumped and smoothed out. Rebecca grasped her breasts in her hands, surprised as milk began to leak from her nipples. “Oh…wow,” she murmured softly, amazed at the sight of her new body.

“Sis…”

Remembering what she was supposed to be doing, Rebecca managed to stand and turned to face her brother. Naturally, he had also undergone an inhuman transformation. His young body was bereft of the baby fat that his mother had always cooed over. Instead, muscle had taken its place, giving her brother’s body a more powerful presence.

“I’m sorry but…”

But the most noticeable difference was the monstrous cock that jutted out almost fourteen inches from his small frame. Terry eyes locked onto his sister’s, his lustful brown eyes locking onto her stunned blues.

“I need to fuck you!”

Terry tackled his older sister to the floor, driven by some animal instinct that had comply overpowered him. Rebecca, aroused at the sight of his changes, spread her legs and let her kid-brother ravish her, his fist-thick cock sliding easily into Rebecca’s throbbing cunt. Apparently, her outer self wasn’t the only thing modified. Her pussy greedily pulled her brother’s dick into her womb, massaging its girth with its warm walls. Both siblings gave squeals of please at the mind-blowing sensations that consumed them.

“Unh! Unh! Sis! Unh! You feel…Unh...so good!”

“Oh, Terry! Aah! You’re so BIG! I love the way you feel inside me! Aah! Aah!”

Terry grabbed two fistfuls of his sister’s tit meat, sending splashes of creamy milk over both their bodies. Her breast milk was thick and fatty like whipped cream and the second Terry tasted his sister’s milk, he knew he’d never drink anything else as long as he lived. Rebecca’s legs wrapped around Terry’s hips like a vise, helping him thrust faster and harder than he could on his own.
