Show off to Josh

She walked up the stairs, her barely contained breasts bouncing up and down as she walks. Once she reaches Josh’s room, she takes a quick peek inside to see if he’s in there. Sure enough he’s in there, sitting on his bed with his girlfriend no less! That’s good, Liz wanted a spectator.

Doesn’t even bother knocking, she burst through the door, careful not to bump her head on the door frame. She stared down at her brother and his girlfriend, both absolutely terrified at this massive Amazon suddenly crashing into their room.

Josh fell off the bed, and quickly scampered onto his feet. Even while standing, the height difference is clear. His forehead barely reached Liz’s chin.

“W-who are you?” His voice trembled as tried to square up to Liz. Oh dear, Liz giggled when she realized Josh didn’t recognize her. Oh well, let’s play with him a little bit.

“Oh, you really don’t recognize me? You’ve been looking after me your whole life and you can’t tell who I am?”

Josh stopped cowering when he heard her voice and finally recognized his sister. “L-Liz?” Josh stutters his words, unable to believe this massive amazon is his sister.

“Yep! I can hardly believe it too! I’m sooo much bigger than you now.” She says, leaning over her brother, enjoying looking down on her older brother. “Especially down here….”

“Down where; oh-oooh my-“ Josh’s eyes nearly popped out his skull when he saw it. His sister’s cock is MASSIVE, dangling just past her knees. It was thicker than his own muscular arms, the cock head the size of a small orange. Massive veins thicker than his pinky snaked through her cock, and through her grapefruit sized balls. His girlfriend was alarmed by his sudden screaming and walked up to him to see what’s wrong.

“Is everything okay, baby- WHAT THE HELL!? IT’S HUGE!” Josh’s girlfriend screamed at Liz’s monstrous endowment. Liz grinned with pride as she looked down on her brother and his girlfriend, both of them in complete shock of the woman she had become.

“Y’know Josh, I know I’m big, but I’ve had some trouble figuring out just how big I am.” She flexed her arms to show she wasn’t just talking about her cock. “I’ll need someone to measure meee…”

Josh’s body moved on its own, grabbing the tape measure he uses to measure his muscle, when he first started working out. His girlfriend friend started circling around her, her terror and confusion replaced with curiosity, trying to find any clues of how she grew so big.

“Hold on, wait!” Liz shouted, they both froze, waiting on her words.
