What will you change next?

Your father

It's unfair for his mother to be the only one getting some changes. John looks at his father. He remembers walking in on him fucking his mother once. At the time, it seemed like his dick was huge, but now that he is older, he knows that his dad is below average.

With a snap of his fingers, John's dad is now bestowed with the kind of monster cock John thought he had back then. John can't see it right now, but he knows that his dad is packing a foot long, girthy monster that could destroy any woman.

With your new modifications in effect, it's time to put them to work.
