“Ok, I'll grow you to my size,” you say, “ but I think we will have to go somewhere else, we could cause a lot of damage if we stay here.” “But, where would we go? Where on earth would could we go without destroying anything?” Asks Kyoto. “Oh, I have an idea.” you reply.
You concentrate really hard and the three of you are suddenly sounded by nothingness. Then, you think some more, and you were standing right back to where you were before. “What did you do?” Misuzu asked. “I've created a separate dimension for us to have fun in. Time is frozen, we will never age in here, and we will never have to eat or sleep. When we go back home, people will not notice any changes. Also, the earth here is completely devoid of life, other than us, we can grow as big as we want without the risk of crushing everyone. The structures still remain, so if you are feeling destructive, go right ahead” you reply. “So, I'll grow you until you say to stop, I will also grow your breasts roughly twice as fast as your height, the same goes for your hips. So, who wants to go first?”
“Come on Nayuki, Kyoko got to grow before me last time, please let me grow first!” Misuzu asked while jumping up and down. You decide that thats far enough and nod your head.
You imagine Misuzu growing larger and bustier, as she starts to moan with pleasure. After only 5 seconds, she is 300m tall (the previous author used metric, so I will follow suit), with R cup breasts. “Oh Nayuki, don't stop” she moaned wile massaging her larger breasts. At 1km her breasts had grown to Y cups, about as large as your own. “Kyoko, I'm sure you would like to ride in my cleavage, so here you go.” she said in between moans, as she picked up the now tiny Kyoko, and placed her in her 500m deep cleavage.
At 1.5km Misuzu's breasts were going to touch the ground while she was standing up! “Nayuki, could you stop the growth of my breasts and hips for a bit, they're big enough now. Her breasts were ZZZ cups, and were down to her ankles, and stood out 1 km from her chest! Her hips were a bit wider than she was tall, at 1.75km! You agree, and stop growing her breasts and hips, but grow the rest of her faster. 3Km, 4km, then 5km go by and you hear a cry for help from Misuzu's gigantic breasts. “ Misuzu let Kyoko out of your cleavage, your suffocating her.” you say. “Ok. Here you go Kyoko!” Misuzu yells out as she pulls out the now tiny Kyoko from her roughly 4.5 km deep cleavage. “Thanks,” Kyoko says, “but can I ride on you nipple?” Misuzu places Kyoko on her 600m long left nipple. Kyoko was only 73m tall, so she could stand on the nipple with ease. Kyoko started to massage Misuzu's nipple, and Misuzu started to moan with even more pleasure.
After a few minutes, Misuzu had reached your height of 9.6km. You stop her growth walk over to her right breast and start to massage it. It was so large, you could not get your arms even half way around it. “So Misuzu, do you want to continue, or do you want to give Kyoko a chance to grow now?” you ask, looking at the speck that was Kyoko on her left nipple.
