Jack heard the playful laughter of children. Looking out his window, he saw the neighbors 8 and 7 year old daughters Mia and Maggie playing in their backyard sprinklers. Mia's long blonde hair, and Maggie's long red hair trailing behind them as they played in their little one piece bathing suits. Judging by the saggy crotches, Jack guessed, that their mom got their suits slightly too big to allow room for growing.
And grow they would...
Jack remember two months after he moved in Mia told her mother that he was watching her and Maggie. Naturally being a 23 year old single mother she was alarmed and called the police. They came and questioned the girls as to what happened. Finding out that he only looked at them they only questioned him for follow up procedure. Ever since then their mom was a bitch.
Jack had an idea. If Maggie wanted to act like her and her sister had goods, then why not give them some. First he needed to make some adjustments on his device. I wish this thing had body part selection, rate of growth settings, and it was digital. The switches on the device disappeared and screen appeared. Jack set the settings to progression, physical, reality off, breast, DD, and super fast.
Opening the window pointed the device at Mia and Maggie. The invisible ray hit them as they started another run through the sprinklers. On their first step Jack saw the conical breast buds as their flat childish chest started blossoming. By the second step AA cup mounds had filled any extra space in their bathing suits and the crotches no longer sagged but were sung aginst the little twats. On the third step two A cups were plainly visible on each girl, with a hint cleavage, and their bathing suits were so thought, every detail of their bodies were now on display. On the fourth step their B cups were over flowing the tops and sides of the bathing suits, which were pulled so tight they had serious crotch wedgies. By their fifth step they were C cups , they both yelped as their bathing suits seemed to explode under the strain of their new endowments, fully exposing ther prepubescent little bodies. Losing their balance they stumbled. On that last stumblings step their boobs reached D cups, they started to fall, before they hit the ground both Mia and Maggie were each sporting a set of DD's that would make any full grown woman jealous. They screamed in terror
And then.........
