Jeff saw a package called "Family Package", he decided to investigate; so he clicked on it. He saw a table of info pop up; he looked through it. Jeff learned that the Family package allowed him to change his parents and who they are and he and his sibling will be affected appropriately by any changes to his parents. He can also add or remove siblings and choose to change his extended family as well. And lastly his house would automatically change to accommodate.
Jeff saw his mother Amber in the mother section and his deadbeat father Hank in the father tab. Jeff selected his mother and decided to check her stats. Jeff saw alot of info regarding his mother appear on the screen; he was slightly overwhelmed by the info. Jeff saw he could search for any info he wants. Jeff searched for who his mother love/likes; he found out she likes their neighbor Gabriel. Given that Jeff's father had abandoned them years ago it was little wonder she fell in love with their neighbor.
Gabriel was 26 and his mother was 48, but given that Gabriel babysat him and his little sister Emily, Jeff knew his mother would like him alot. Jeff also liked Gabriel, he was a good babysitter to them. Jeff decided to however make things interesting; instead of putting Gabriel in to replace his father Jeff put him in the mother section and moved his mother to the father section. Gabriel was now Jeff's mother but still a guy and Amber was now Jeff's father but still a woman.
Jeff then de-aged his "Father" to be the same age as Gabriel. Jeff saw he can make adjustment to how the changes will work. Jeff altered so his parents will be aware of their changes but believe the changes happened before Jeff was born, any physical changes will happen slowly; taking 2-5 minutes, make them horny, and they will change while having sex. Jeff then saw an option that would allow him to change his parents into anything without really affecting him or his sister/siblings. Jeff explored the option and found an example of how it would work.
EX: He changes his parents into 3 story giants, he would only grow to 6'2" allowing him to move around society as normal or if he gave his father a 9' horse cock, his cock will become a horse's but will remain at an average size for a human.
This gave Jeff plenty of ideas. Jeff decided to first change his sister separately from the package. He selected her and gave her butterfly wings and made it so she believed he had magically given them to her on her birthday. Jeff saw that his relationship with his sister improved. Jeff then returned to using the package and selected his parents. Jeff used the package to make sure that his parents were madly in love each other and that his sister has memories of Gabriel being her "mother" and Amber being her "father".
Jeff knew the package automatically did this but he just wanted to check and make sure, just incase he had screwed up somewhere. Jeff then stopped to check his memories and found he now had two sets of memories. He had memories of when it was just his mom Amber and memories of Gabriel and Amber being his parents. Jeff felt much happier with the new memories then the old ones. He knew that he and his sister were much happier and love their parents more then they did before.
Jeff knew he was going to change Gabriel from male to female, but he didn't know whether to turn Amber into a Herm/Futa or male
With that in mind Jeff decided to change his parents.
