The first few seconds nothing happened, Mark feeling silly for having ever thought that he could grow people and even alter reality just by thinking about it. But then he noticed that his eye level was no longer at the same height with Jessica’s chin, it now was at her neck.
‘Is she growing?! No, wait, she’s probably on her tiptoes…’ he thought.
Looking down however, he could see how her feet were firmly on the ground. Jessica had always impressive feet, wearing a size 13, but now Mark could see how the perfectly pedicured toes were slowly encroaching towards him, their innocent wiggles telling that Jessica was not noticing anything.
‘Holy shit!’
Mark looked up again, finding himself at the same level as Jessica’s breasts. He blushed, the two globes of flesh had also grown and were mere inches from his face. Jessica had to be about 8 feet tall now and he was sure he could bury his head between those mounds… and they were only getting bigger.
He imagined her becoming double her current height, so 12’6” (381cm) so there was still a lot to go, in fact Jessica continued to rise. Soon her boobs surpassed Mark, then her navel, then her crotch. Finally he was at the same level as her lower thigh, the huge mass of bone and flesh about as thick as his shoulders.
‘S-she’s huge! I must still be dreaming, right?’ Mark thought, pinching himself on the cheek. It hurt so no, it wasn’t a dream.
Looking up, he saw the now truly huge Jessica looking down on him. It was rather difficult for her since her view was partially covered by her colossal breasts, each one way bigger than Mark’s head. They probably were the same size in proportion but they probably were the biggest breasts in the world.
“Say sis, how tall are you?” Mark asked.
Jessica giggled “Why are you so obsessed by height today? I’m 12’6” tall, been like that since I was 16 if you can’t remember.” she replied.
Now Mark COULD remember, a flurry of new memories hit him like a truck: Jessica had always been way taller than the average, doctors diagnosed her with a particular form of gigantism that caused amazing growth without any side effect. She was by far the tallest woman in history, so big that the family lived in a house specifically designed with her size in mind. In fact, the kitchen became much, much bigger than before.
“It’s just… it’s always impressive to look at you.” Mark replied, not sure what to say as he was still in shock.
“I take that as a compliment!” she said, squatting down to give her brother a kiss on the forehead. The lips covered most of it, the pressure was enough to push him back a bit “Now, can we eat breakfast? I’m kinda starving.”
Mark looked at the table, raised so that Jessica could comfortably sit on it. He could also see that her breakfast wasn’t just a couple of toasts now, but at least two packs of them.
“Uhm, sure…”
