You bend down and write: "My growth hormone is simply incredibly powerfull".
With that, a surge of energy rushed through your body once again. This time, it lasted longer and you grew bigger at a rapid pace. You grew another 3 feet within seconds, which made your height around 15'8", almost touching the ceiling. You grew wider as well, your boobs expanded to the sides, nearly touching the walls. Your ass cheeks got much bigger and more muscular and plump, making them the same size as your breasts.
With these new recent changes, you feel as if your body is constantly surging with energy.
Melissa was completely dwarfed by your towering height, and you couldn't help but giggle. "I must be around 3 times your size now, maybe even more. What a sight it must be to see a giantess towering over you."
Melissa looks up at you and rolls her eyes. "Yes yes, how great, now can you move? You're taking all the space here, and you're starting to make a mess."
She was right, your ass was pushing and pressing the wall and furniture around the room, and your breasts were also squashing the desk and the typewriter, and the bed was being pushed back.
"Well, how about this then." you bend down and type; "everything around me gets big as well."
With the last stroke of the sentence, the room grew 3 times bigger, and the furniture and your body adapted. The bed was now the size of a king sized bed, your desk was a normal size, the typewriter was still the size of a toy, and so was Melissa.
You looked down to Melissa, who was staring blankly.
"Uhm, could you bring me a cup of water from the fridge? I'm getting a little thirsty.."
"Fine.." she replied. She walks out the door, and you could see her small figure going down the stairs.
You sit down on your new gigantic bed, and start thinking about what to do next.
You had the thought of growing beyond the roof and becoming a giantess in real life, but you don't want to make a mess.
Your thoughts are interrupted by Melissa bringing you the cup. She places it on the table, and asks, "Is this enough?"
You reply, "It should be."
You grab the tiny cup, and lift it towards your lips. You take a sip, and it seems to work just fine.
You finish drinking the whole cup, and hand it back to Melissa.
Looking back at your typewriter, you began to think again.
