Red, who feels weird around his Charizard, and notices his dick shrinking

Red was always the quiet type, but he showed distress when he noticed his dick was shrinking. Not only that, but he had dreams of being a female Charizard, and having sex with his own Charizard, Flare.

Things were getting weird, but Arceus knew why. Red's DNA, now 80 % Female Charizard, was going to eventually break through. The change was caused by a substance he accidentally stepped in. Charizard's lustful energy was able to manipulate Red's DNA because of the substance, so his fate was set in stone; He would become female, and would become a Charizard, and become Flare's mate.

Arceus appeared to Red in his dreams the night before he would permanently become a Female Charizard. 'Red, you should know that you'll wake up as a girl.'

Red kept quiet after hearing that, but was screaming internally.

Red woke up to see (s)he had a vagina, which had ____ scales growing around it.
