The amazing growing sister show

It lasted longer than last time, and again, was an even more dramatic growth than the last one. Josh watched as her muscles spasmed and thickened, her legs lengthening, and her breasts inflate. Liz screamed in ecstasy as she stretched taller than ever, her spandex began to tighten as it filled with her increasingly rounder ass, and also bulge as it filled with even more Liz cock. All of her muscles had plumped up to a noticeable definition through this, and this strangely aroused Josh immensely.

Finally after it was over Liz stumbled backward. Josh was panicked, his 19 year old sister grew just before his eyes. Her nipples were nearly 4 inches long and her areole was the size of a saucer. Liz came out of it and was just becoming aware of what happened, she didn’t expect to grow in front of Josh, and felt uncomfortable for some reason, and ran up to her room before the sexual tension caused any more growth spurts. As she reached her room she was overcome by fatigue, most likely from the unnatural growing she had done all day, and stumbled to the bed and passed out.
