Your little sister walked towards you pulling on your skirt. She looked up at you “I want to know what it's like to be that tall too like Kyoko. Please!” Misuzu begged infront of you. “Now now, you don't need to get all that way. You know I don't want to keep you behind on anything.” you petted her head while you still could because you already saw your little sister was slowly getting bigger aswell. Filling up her clothes really fast giving them little chance of survival. Her skirt was the first piece to fall to the ground leaving your now 7' sister. It now showed her pink panties wedged in between her shaved pussy. Her shirt was now pulled tight across her torso showing her little erect nipples. Though that did not last very long as she got bigger when at 10' tall she stood totally naked infront of you.
“Nayuki, could you blow these up a bit too?” Misuzu asked looking down at you from a height of 33' tall pointing at her flat chest. Looking at your sister you thought she could use some improvements too. So you gave her her wish in that too. Just like the rest of her body grew her tits began to develop into some real D cup breasts. By the time she clear the tree tops at 89' tall these grew to a full I cup. Misuzu started massaging her new assets grinding them in her hands as she grew. While Kyoko was now standing again Misuzu was already up at height of the pink bush above Kyoko's pussy. 123'.. 137'... 159'... 168'... Now her own pussy was clearing the trees around her. “This really feel awesome! I really got to thank Nayuki when I'm done growing.” Misuzu told Kyoko.
When Misuzu stopped growing she stood a good 221' tall now. Her first almost non-existent breasts had grown out to some good O cups, well that's if she were normal sized ofcourse. But they stood 54' out from the base of her chest. Her 7' long erect nipples were being pulled and twisted by some huge hands as you heard some moans coming from your sister.
You decided it's time for your own body to get it's growth turn now that the others have grown so huge. First you focused on your hips to give it some extra width. Feeling your hips are getting wider and the space between your legs increase. If you were to measure yourself now your 3 sizes would've been something like 63-42-105. Your panties are now also digging into the sides of your hips. Taking focus now to your breasts you started making them bigger like Kyoko's are. You felt them grow inside your bra pushing it out to the maximum stress before the straps break. Now they started to fill up your shirt. “Hmm yes, bigger feels better!” you moaned it out as your shirt started to rip apart. They are getting so big now that your shirt now simply gave up bursting apart letting your globes bounce free. Standing now almost 3 feet off your chest your 5” nipples are now pretty much out of reach for you.
Enough of changing body parts now you focused on your entire body now. The tingle returned to your entire body could be felt trough into your bones. Slowly at first your body began it's rise upwards again getting taller by the second. Feeling your already tight panties digging into your pussy it suddenly snapped of when you got up to 11'3” tall. Getting horny from all this growing you slipped two fingers in your now wet womanhood. You pleasured yourself and massaged one of your breasts as you surged up to 42'6”. Now nearly reaching up to the knees of your friend and “little” sister you came to a climax from pleasuring yourself. That gave you almost an instant growth surge to 85'. Slowly you viewpoint got higher allowing you to see over the forest in which you now stood 108' tall. You little sister pussy is now straight infront of your face. You already felt pretty tall now and you couldn't believe that these two were still a lot bigger than you. “Time to catch up!” you thought increasing your size a lot more.
A new rush of growth came pushing you up into your sisters breasts making her masses bounce up and down. “Hehe, oops! Sorry Misuzu. I'm coming up too now.” you smiled up at your sister standing now as you passed the height of her nipples. Then you felt a weight getting heavier and heavier on your own chest. You looked down at your own breasts and saw Misuzu's breasts were now resting on top of yours slowly pushing hers upwards in towards Misuzu's face. 170' tall now and your breasts were a good deal bigger than your sister's are now. Your still dripping wet pussy was now emerging into view from hiding in the forest. This spurt slowly came to an halt when you just barely reached up to your sisters chin at 192' tall. “More! More! This feels sooo good” you moaned beginning a new spurt. Firstly you were looking straight in the purple eyes of Kyoko. But in order to keep looking at her you had to bend your head down. Standing now 288' tall the top of Kyoko's head now only came up to your chin. You gave a smile back to Kyoko thinking of a last spurt that'll be bigger than these last ones you gave yourself. Feeling your whole body tremble and shake from the imminent spurt that is coming. “Better take a step back girls, I don't think I'm done growing yet” you giggled.
Feeling a climax build up until you were ready to burst into orgasm. You eyes opened up wide as you finally screamed it out. “Oh yes! Here I goooo” you moaned as your body shot up again. Your perspective now went up so fast that in just a minute when your spurt stopped you took some moments to get back to your senses. Looking around at first you could see over the entire forested area. Looking down to check on your friend and sister you couldn't see them. You have gotten so big your breasts just blocked your view after all they stood some roughly 170' off your chest with 21' erect nipples. So spreading your breasts so you could look trough your huge cleavage. Now that you could look trough your cleavage you saw Kyoko and Misuzu standing just in height with your crotch. That last spurt grew you some 200' more to a total height of 488'!
