A Mysterious curse has spred across the planet for the past 100 years or so that effects a handfull of young boys every year. These boys are known as Were Moms.
This curse seems to only effect boys ages 9 to 19 and is believed to be passed to them by their Mothers at birth. Once a boy with the Were Mom gene reaches their 9th birthday the curse falls upon them. Every full moon the Boy will painfully transform into a perfect copy of a extremely hot 20 year old female version of themselves. This will last for the entire week of the full Moon after which the boy will turn back to normal in a much more peacful transformation.
During the boys time as a girl, he will think and act more like a mom but will still remember who he was and will keep a small bit of his persoallity with him/her.
If a Were Mom wishes to they can become
there mom permanently. In order to do this they must allow a Man to ejaculate inside of them during sexual intercorse. This will rewrite there DNA as female and once the week of the Full Moon is up they will not turn back.
This is difficult though as since although the Were Moms are grown women in this form they are still technically Kids making sexual intercourse illegal. This doesnt stop secret organizations however from hiring Male escorts to help the Were Moms who wish to stay permanently Women make that possible. Another problem of this is that Were-moms are extremely fertile, and during their transformation, they release 10 eggs a day.
During the weeks of full moons, the real Moms will become the Were Moms best friends. Hanging out with them along with their moms other friends. The Curse greatly changes the relationship between Mother and Son. For one week a month they go from being Parent and child to sister best friends.
Once the boys effected reach the age of 20 the curse for some reason stops. Its unknown what causes the curse to stop. But it is known that the curse gives these boys a very different childhood. Also, if they have any extreme interests before the curse starts, like videogames, then they will change into a beautiful (human perspective) version of their favortie character (not including inanimate objects, or non humanoid animals).
