In this world about a decade ago, girls started to develop tiny penises. People were of course shocked. Pollution, evolution or the falls of moral standards were blamed but the cause was never determined. Some parent arranged operations to remove these aberrations from their daughters but as time passed and more and more girls grew penises, people started to accept this state of affairs as normal. They accepted that girls had a decent chance of having a small penis and didn’t consider it that strange.

What was not commonly realised was that girls were getting bigger and bigger penises as time went by.

Their penises not only grow but girls born later grow at a faster rate.

The girls who had tiny penises a decade ago got bigger as time went by until now they are almost as large as boys.

However the girls who developed penises five years ago grew penises which were close to a boy’s size almost right away and have grown to be significantly larger than the average boy’s penis by now.

The current crop of teenage girls is bigger than boys their age (about fourteen) within a month of the penis developing and continue to get bigger very fast.

The public is not aware of this, perhaps because the media and government don’t like to ask teenage girls about their penis size. Only a few unlucky teenage boys find how large teen girls are to their embarrassment. Most people assume girls have small penises if any.

Koboshi hid under a mat in the gym and gazed down through the large window at the swimming pool. He was horrified. He didn’t like girls having penises and it seemed clear that almost every girl in his class not only had them but were hung. He’d snuck into the gym to peek at the girls’ private swimming class. He’d being hoping to see some firm young breasts filing out swimsuits and he had but… But not one girl had that divine area of feminine flatness.

Every single one was packing a fat bulge running up, sideways or even wrapped in a little circle.

His favourite animes were nothing like this. In them all the girl were gentle and sweet and had nice flat panties areas. They didn’t have those… MONSTERS!

The worst thing wasn’t that the smallest girl there was twice as long flaccid as he was erect.

The worst thing was that his beloved sister Mika… his dear sweet little blonde haired (A few years ago she’d asked mom for one of those new hair color change procedures), angelic little Mika -chan had … the biggest babymaker of all!

The girls ran and dived and chatted and stretched with each other happily. Miss
