stuck as her

Unknow to David was it was Nancy's most fertile time of the month so when his son came inside him some of his swimmers took hold with out him knowing until he tries to change back and nothing happens so he continues to test his device everything works changing back and forth but for some reason not him so after a week he finally breaks down and tells his son who he really is causing Jacob to initially freak out once he gets himself under control he asks his dad why he doesn't change back. David says he tried but it wont work on him for some reason he then says maybe something happened because I become a fully functional version of Nancy he says I hate to ask but this is the only thing i can think of might be a possible cause of me not changing back and gives Jacob some money and sends him to the store to get a pregnancy test to check his theory. it has been a few weeks testing

After a few minutes Jacob returns with a bag and pulls this out

David Takes it to the bathroom with a worried look on his face and follows the instructions and takes the test and waits the the amount of time it says to and hands it to his son with a worried look on his face as Jacob looks at it here is what he sees

and they both have to decide what they are going to do.
