A torrid transformation

John waddled along the hallway, swinging his massive manhood with every alternative step. Now that he'd boosted himself enough to carry her he was really getting off on living his fantasy. Melanie now existed for his pleasure in between his legs he could feel her twitching with anticipation. He was going to give her a lot of deep places to bulge.

He walked forward, rubbing his hands across the top of what had been his sister's head occasionally moving down to lick and kiss the massive angry crown. She tasted good in the sensation of fellating himself felt amazing. He took an experimental lick along the slit and pleasure made him immediately fall backwards from the stimulation.

He was going to have to deal with this first.

He groaned his muscular chest began to swell his pectoral muscles transforming becoming softer and untrained before swelling like a pair of balloons. He would have his fun with Erica later right now his own body was going to satisfy him. The transformation was already starting to overtake him. His short cropped hair growing a long and silky similar to the sister he had already assimilated into himself. His lips swelled up and his hands became softer and more delicate as they stroked up-and-down Melanie's massive bulk. He heard his own moaning raise a few octaves as he continued to show love for himself rubbing his massive knockers around his shaft trying to swallow the tip.

It still wasn't enough

John felt his jaw and hinging as he swallowed the tip of his new member like a snake swallowing an egg.

More, he needed more.

Snap two more arms began to move up and down his shaft massaging places that he couldn't swallow or wrap his impressive cleavage around.

Then he heard the gasp. He lifted his head just in time to see the horrified face of his sister Erica.

He smiled
