Growing more...
...Excuse me for poor B/W drawing...
.... Special thanks to Watari for translating in English ....
Rika-san lives next to my home, She is 6 years elder than me, junior year in the university.
Her parents and mine are very friendly each other, and that both Rika-san and I were single child.
So she has taken care of me like a yonger brother from a little child, and I become attached to her like a true elder sister.
Rika-san is very clever, she got into the university at number one ranking.
There is nothing surprising that my parents asked her to be my tutor for the examination for senior high school.
But, in these days…I have begun to be interested in Rika for another reason.
Rika-san is tall and gracile like a foregin model, celebrity. I expect that she is 10cm taller than me.
If that's all about it, I will probably catch up with her height when I enter senior high.
I can't get out my mind that Rika-san is changing her figure.
Originally, she was very slender and tall as girl, as if she was a fashion model. However, I somewhat feel that she grows more glamour and voluptuous than spring when she began to teach me.
It becomes clear that my "imagination" is truth when we break up for the summer vacation, after four month since she'd tautht me as a tutor.
It is very hot day. Therefore, Rika-san meet me with her amazing too casual apprearance she usually never wears...she puts on tight tank-top and hot-pants.
Before my eyes, she looks very intelligent beautiful features with glasses from her face up, but from the neck down, I've never seen such her figure as before.
Her breasts bounce out her chest like torpedoes as if it packs two rugby balls as half, it blows up tank top intensely. A drop between breasts and waspy thin waist seems to be over 20cm or more.
As I surprised, Rika-san smiled wickedly and gave me a reason.
She specialized in biotechnology at her university, and the professor who instructs her in charge is the global authority by composition of somatotropin.
What I surprised that Rika-san has helped him with the study from a second grader, and then since the beginning of this year, he extracted the hormone from her pituitary gland and adjusts it, and she received injections of it, and they research how much effects a growth factor.
"…Mmmm, by the result, I seem to become such a glamour girl. …Are you worried about me? fufufu...You are Man, Boy..." she said with a chuckle.
"And I am surprised at a little, it doesn't effect slowly, I grow up in a short time suddenly once…
It's happened in one or a half day, if it's fast, in two or three hours...
I'm in deep trouble not for entirely predicting when it happens, in addition, a ratio of growth somewhat seems to gradually grow larger...
Please not surprise and be scaered, if it happened to me with you. I'm begging you."
One week later.
We change and loosen up the atmosphere a little, I have her taught study in living room.
As Rika-san advised me in various ways, suddenly she shut her mouth, quiet.
"E, Excuse me, i..it's going to happen..."
( mmm..."IT"? "It happens"? ) I were about to remember it... next off.
Like special effects movie, a chest of Rika swells up and up out rapidly…
Snap! I hear a frightful sound from her back, A hook of a brassiere split open and flew. And…
Riiippp!! Her shoulderstraps break and split open, her light-brown soft fair skin begins to protrude from tight tank-top.
As surprising I stand up, I look at her eyes on the same level who now squats on her knees.
She is growing not only breasts but also her body as a whole...
Rip, Rip, Riiiippppp!!!
Beyond bearing the pressure of expanding her body, her tank top and hot pants are torn up in a moment,
already growing Rika-san body is now expanding one size, or twice larger than before.
Her breasts is now growing as big as my head, they sway and vivrate lewdly in front of my sights.
"Oh my...No! Don't look at me!!"
Rika-san covered her voluptuous chest and crotch by hand in a hurry, and stood up.
Bazoooommm! As I heard frightful sound, her head hit a ceiling. However, she rose only her knees, her growth didn't stop yet.
Rika-san's living room is very large, and there was a ceiling more than 3m high, but her head began to push up and crack it in a moment.
Meanwhile, I looked up her breasts over my head, they swell up immense size that her few scraps of tank-top and brassiere sticking to. Now they grew up as if I never held with both arms, and due to them, her embarrassing face was lost my view.
Her incredible breasts protrude over 1m from her chest as if they were an large fresh balance ball. As she still grew on and off, along with her growth, they immense weight waggled and swung back and forth.
Squeakkkking! I noticed the ceiling began to make unpleasant sound... But Rika-san's huge body continues to grow up still more and more...
I can't move as if I was petrified with awe, or her attraction? I can't help but keep my eyes on her too voluputuous body now still grew up and up rapidly.....
