"You really are a natural at this! Maybe we should take things up a notch..." Cindy giggled deviously.
"What did you have in mind?" her apprentice smirked.
"Well, as I told you, I plan on conquering this planet and its pathetic inhabitants, but it's taking much longer than expected. Your people are quite the resilient little bugs."
"Please, Cindy, don't ever loop me in with those weak little insects ever again," Alyssa demanded. "I was human, but I have ascended into a goddess now. Now, these little humans are nothing but annoying pests that don't deserve to gaze upon my ascended form."
"My word, Alyssa, you shall make a fine goddess indeed!" Cindy praised. "Now, as I was saying, I wish to rule over this world as soon as possible, so I think a more intimidating figure is needed, don't you think?"
"But of course! Let's do this!"
"Excellent! Get ready!"
With but a simple thought, Cindy focused on both her own and Alyssa's bodies and began to infuse them with her own mystical energy. Once the connection had been established, the original giantess sighed in pleasure as she broke her focus, causing her and her apprentice to rapidly climb in height.
"Bow before your goddesses, you insignificant germs!" Alyssa commanded as she watched the city shrink before her very eyes. The humans within the city merely looked up in both shock and awe as both girls grew taller and taller with ease, their increasing shadows slowly beginning to cover sections of the city in a wave of darkness.
After about 30 seconds of solid expansion, the two women's growth spurts came to a halt.
"Now this is more like it!" Alyssa laughed as she glared down at the minuscule city before her.
"This size will do nicely...for now at least," Cindy chuckled sinisterly. "I should've been this large right from the beginning!"
"Ya know, Cindy," the beautiful blonde goddess began, "we have an old saying on this planet: 'Bigger. Is. Better.'"
"That's such a wonderful little quote, dear," the stronger being giggled. "I do hope this'll be enough. I made us equivalent to 750 feet tall in your Earth measurements. We should have no problem bending this world to our will now. And of course, if ever the need arises, we shall become even stronger!"
"That sounds perfect! Now, shall we begin?"
"Let's!"
