Jenny asked Jeff if they could swap genders, she wanted to see what it was like on the other side. Jeff agreed, but decided to make things interesting. Jeff said "Hey Jenny why don't we use the Chronivac add want we what to see in our and each other's genders and make it the gender swap effects everyone?"
"What do you mean?" Jenny asked.
"You and me will put down what we believe would be the ultimate male on our cells and the Chronivac will combine both, then we do that for females and then the Chronivac does the same for females, then we apply the changes to the genders, but it won't effect us right away. I want to have sex while we slowly swap genders."
"Hmmm, sure why not, it means I can make myself into a strong man, if you don't try and sabotage males." "Oh lets also bring my Father Gabriel over so we can compare an adult to us, since we have your mom to compare me against, I want to see how you compare."
"Sure." Jeff agreed, Jeff then used the Chronivac to bring Jenny's father Gabriel to his house. He altered his mother Anna's memory and Gabriel's memory into thinking Gabriel brought Jenny over for a school project involving sex and Anna asked Gabriel to stay just incase Jeff needed some tips from a guy. Jeff smiled slyly as he gave them such a lewd reason. Now unto the fun part, Jeff thought. Jeff put a copy of the Chronivac into his and Jenny's phones that was connected to the main one on his computer. He then made it so the Chronivac will combine their changes to the Male and Female genders before automatically applying their changes to the world and starting a timed change for him and Jenny.
Once he was done Jeff got off his computer and sat on the floor motioning for Jenny to join him sitting. Jenny joined Jeff and Jeff told her to take out her cell and start making changes.
Jeff and Jenny furiously moved their fingers over their cells as they began to alter Men and Women.
Once they were done they submitted their changes to be combined. Jeff then told Jenny they should put their cells on his desk and get ready for some fun. Jenny smiled also feeling excited and the upcoming changes even if she didn't exactly know what exactly she would become. Once their cell were away, Jeff and Jenny began stripping.
They quickly became nude and Jenny went to lie on the bed. Jeff followed after her and they began to make out.
It wasn't a few minutes after they felt the tingling of their changes come on.
