Nikki was happy with the changes that had been made to Jessie and Chris, but seeing how many options the Chronivac had had left her wanting more, and she had an excellent idea on how to get what she wanted. She loved the sex she'd had with the two of them, but the thought of having more cuntboys to fuck was making her dick hard, so while she had been making Jessica's changes, she set up something else. Jessie and Chris would now both believe they were the first cases of what would come to be known in the world as 'the cuntboy virus'. To help this virus spread, Nikki made it so that it was transmitted sexually. Anyone who had sex with an infected person would either be turned into a cuntboy (if they were male) or become a carrier for the virus, passing it on (if they were female). She also increased the infected's libido, to help it spread further. She smiled to herself as she entered these changes into the Chronivac, excited to see how the virus would spread, rubbing her fully-hard dick as she thinks of all the cuntboys that'll now be out there, ready for the dicking.
