But your thoughts of being a 20-foot tall teenager were cut short when you experienced a now-familiar tingling in your back. It took a few seconds for the realisation to kick in; you were growing again.
For ten or so seconds you panicked, worrying that you were growing without even thinking about it. But soon a new thought crept into your mind: "Why not? I quite like the idea of a forty-foot Nayuki..." You giggled to yourself.
As your already huge frame expanded even more, your thoughts swayed to your body's seemingly constant quest for size. You thought of being the size of office blocks, people seeing you from streets away, and having to run to avoid your titanic feet pounding the pavement. Thoughts of a stunning, 10-storey, 16-year old with breasts the size of small houses swirled around in your mind.
"I'd be huge... The Earth's next Goddess. I can do whatever the hell I want, why should I care if i kill a few... or a few thousand people? It'll be their fault for not getting out of the way... They'll be staring up at me, at my amazing body, and I'll be able to do as I please..." It was clear that your mind was making plans, and you had no intention of changing them. Nearing 35 feet, your previously huge miniskirt was obviously not huge enough, now lying across half the street below. The blue tank top was barely holding on, it had already torn at one seam and the bottom barely came up to your ribcage, showing your huge, flat stomach, whilst offering a spectacular view of the underside of your magnificent rack.
At roughly 45 feet high, you could see over the tall office buildings in the street, making you realise for the first time that you were a real giantess. It hit you hard that this was actually happening, that you had gone from a perky, short and underdeveloped sixteen year old, to the largest creature on the planet, a gorgeous mountain of a woman with boobs the size of lorries.
Peaking at around 60 feet tall, you were the largest thing for miles around. Coming back to your senses, you saw not only the black mini skirt draped across the road, but shreds of tank top draped across lampposts, buildings, and even your bust. As you removed pieces of clothing from your cleavage, you realised: You couldn't even see the ground, your mammoth boobs jutting out a magnificent 22 feet from your chest. You moved your hands to get a feel of your new assets, experiencing their softness, their roundness and yet their extremely firm nature. They stuck out almost at ninety degrees from you even without support, and you felt you could bring down buildings with them.
You then decided to explore the rest of your new body. Your hair was a thick, lustrous shade of black, stretching halfway down your back. Crouching down and looking in the reflections of the office blocks' windows, you could see your eyes had gone from a dull brown to a deep blue, your face was beautiful, your cheekbones raised and your neck was relatively slimmer. The changes had given your stomach slightly more muscle, making it hard and flat, and more svelte in appearance. The new curves had given you longer (obviously XD), sexier legs and your feet could easily crater streets.
You had gone from a 16-year old girl, jealous of her sisters, to a 20-foot giant, and then to a gorgeous, sixty-foot sex kitten, or actually, more like a sex panther. And now, with a huge grin. this sex panther had some decisions to make...
