Nipping this in the bud now, Lynda made a few adjustments to the world. Prior to 18 years girls will still develop just like they had gone through puberty normally with the exception of their nether regions; to symbolize this she added a birthmark to young girls above their vagina that would be a contrasting color that would over time fade until they turn 18 where it will disappear completely, feeling clever she also linked their sexual sensitivity to how faded the mark was, she wanted them to feel free to explore their bodies but prevent it from getting out of hand.
Checking back in on the family, Lynda found she was enjoying watching how things were playing out with the changes she made more and more.
At first there was no difference, the eldest and second oldest were making out and began feeling and fondling each other's bodies. Things were about to escalate when both became confused nothing was happening to them like they expected, there were no juices to exchange from their vagina’s, and not only that, there was no pleasure, the look on their faces said “this was supposed to be more pleasurable but instead it just felt like she is rubbing my arm.”
They disentangled and climbed out of the river to inspect themselves.
Upon inspection they noticed the new marks about where the womb would be, it looked like a dark bruise on their relatively white and olive skin. As they ran their hands over the mark and experimented touching themselves they felt no pleasure, it was just gone. Panicked they ran back to their parents to relay what happened.
The parents were baffled by this change obviously they seemed un-affected, Ash seemed to understand if only that the change was to prevent them from playing in that way for now but didn’t really understand what it meant or why.
For now the parents just comforted their two eldest daughters.
