Mariam's growth did stop eventually, as she reached an astounding height of 10'3''. Her family had her checked by the doctors, and the sports comitee, and she indeed had stopped growing. Although she was much taller than the next tallest man who ever lived, whom closed at 9 feet, they were unable to find any kind of illnesses that could explain her enormous height.
The cientists theoryzed that she was lacking the genes that restricted growth on the human body, and this lack of restriction made her grow where no man had before. Asking her collaboration for a two weeks testing at the Bayer's industry research labs, Zeineb advised against it, but, as the money was good, and the fact that they could not keep up with a giantess athlete appetite, they all felt it was a necessity.
When she returned, they found that she had gained another 3 inches, to her already gigantic body, which made her crouch before some old powerlines in their neighboorhood.
She told what they told her, pleading for they to keep secret, as they were secretly testing her. Marian could have indeed no restriction to her growth, but beyond 10 feet it would be so much protein and calcium consumption that it would be a lot expensive and it could posibly beggin to hurt her.
Anyway the implications could last on a new drug that would be the best pharmaceutical discovery since penicilin, allowing to treat people from growth disorders, or give an edge on sports teams over the world. Or that it could be an event limited to Mariam's and Zeineb's family, and by such, they needed to test her sisters.
Layla was the first to volunteer into testing, as she hoped that growing a little would help her chest look smaller, as her 34 EE were such a pain in the back of the 6'3'' old lady. Amani was a bit relutanctly at first, as she was the "mostly" normal of the girls, but thinking about the money, and that she definetly needed a scholarship, that would be hard to get without standing "above" the average girls. Plus, she had the support from her 6'4'' boyfriend, who thought it would not hurt her growing a little.
Zeineb thought that she could regain hope at volleyball, even though she was alredy 25 years old, but relutanctly she said she would have to thing some more before any testing could be done on her. So they took the girls on a two months "vacation" at the test labs.
By the end of the primary tests, they returned home, much to Zeineb's, and her mother's and father's shock:
Layla was 7 foot and 5 inches tall, and Amani was 6'11''. Even themselves could not believe how short Zeineb were, she was always towering everybody.
Zeineb's shock was the greatest, as she hadn't known any taller family member since she was 12, with the exception of Marian's spurt.
Amani was decided to try the volleyball, so to make the third family member the charm. Layla did not know, but she was inbetween basketball and something called amazon sessions, a job very famous on the internet, employing 7 foot women whom dominated shorter men, but she was afraid of telling her parents about it.
Mariam was not impressed, as she thought that her sister were just a little less shorter than they used to be. She was looking forward to the payment of the lab sessions, and going to the mall right after, to buy something more decent than window curtains as dress.
All that new situations just made Zeineb wonder
