Jenny immediately suggested that they use the Chronivac to change their families.
"Elaborate your plan to me then Jen" asked Jeff.
"Well, I want to change myself, but it would be awkward if my parents don't change, I also don't want to change the world at the moment. So I thought just changing our family lineage will be enough."
"That makes sense then. You can go first then." Jeff said as he got off the computer.
Jenny immediately replaced Jeff at the computer and went to work.
First thing Jenny did was use the Chronivac to copy itself to her computer and made sure Jeff would never find out. With that done Jenny went to work on her secret desires. Jenny besides having wanting to change herself, partially used the desire to change their family lineage so she could get closer to her father Gabriel since she was stuck with her strict mother. Ever since she was 12 realized she loved her father and she wanted to be closer to her father, she also realized she was Bi, so her kink/desire was to turn her father into a woman.
Jenny only altered her father's lineage and made sure she would get the complete effect from it. She did alter her mother to be a herm/futa and that her mother was still married to her father. She began to alter her father so he was the perfect combination of a succubus, a dragoness, and an echidna. She then went on to change his body figure to make it again the perfect combo of three body types, MILF, sexy model, and amazoness, with tits the size of his...err her new head. With her father's now mother's body set, she altered Gabriel's history. Her oldest ancestor was Lilith the mother of succubi and Echidna mother of monsters, eventually leading down to her family. Her father/mother was born male, until he became 14, when he awakened to his bloodline, turning into the sexy hybrid Jenny made. Jenny was then born from Gabriel as her mother and Gabriel kept his/her name. Targeting herself she made it so she would essentially be a slightly smaller version of her new mother minus the Milf shape and she could grow a draconic cock at will, but she would never do so when her boyfriend was around and Jeff would never find out. Jenny made it so Gabriel was queen of the hell and thus she was the princess of hell. She did alter some things that effected more then just her family. She made it so incest between her and her parents was fine and Jeff would participate in threesomes or foursomes with them, she would only use her cock when it's just her and her mothers. Her two best friends would join in foursomes or fivesomes with her and her mother(s) or just have sex with her or her mother(s) and Jeff being unaware of this. The very last change she made was that she would always be taller the Jeff, his head would only reach up to her tits when they are fucking.
With her stuff done she added a condition so that the changes she made will only happen when Jeff hits accept on his changes. With that done Jenny switched the screen over to Jeff's status on the Chronivac and got up to let Jeff use his computer.
Jeff replaced Jenny on the Chronivac and thank her for switching screens.
Jeff got to work to do as his girlfriend suggested. Jeff decided to make his entire lineage into werewolves. Of course Jeff wasn't so uncreative as to just make his family into the bog standard werewolves, he made it so instead of changing because of the full moon, they would change when they get horny. He also made it so they are immune to silver, in their human form will have no indication they are werewolves and when they change they can only change back once they had a good fuck.
Jeff felt satisfied for now, knowing he could always change things after. Right now he was more excited to see what his girlfriend turns into.
He accepted the changes and waited for the Chronivac to change them
