While she fucked her parents, it didn't go unnoticed by Jen that several people in the neighborhood were changing. She wanted to give pleasure to all of them, but there were so many and in so many ways that she didn't know how.
With this desire in mind, Jen's transformation took an unforeseen turn for everyone. With this desire in mind, Jen's transformation took an unforeseen turn for everyone. She suddenly stopped moving, which worried her parents enough to stop fucking each other, especially when their daughter started to get transparent. Unseen by anyone, Jen had evolved into an all-knowing, all-pervading being, which filled the entire planet, quickly filling the entire world's air with her pheromones.
"It can't be, Jen disappeared." Helen said, startled.
"But why? Does it have something to do with the changes we've undergone?" Alex asked
"Dad, Mom, don't worry. I've never been better and now I can pleasure everyone." Alex and Helen heard Jen's voice inside their heads. Soon after, Helen's asshole opened and she felt a penetration, then an invisible movement with a very large cock, even for her current size, fucking her, at the same time the sensation of pressure around the three her dicks, like she was fucking someone with all of them. Alex's pussy was also wide open by an invisible force that fucked her too, and she felt her breasts being sucked. The same reaction happened to all the transformed, who began to have sex with an invisible existence.
Meanwhile, people transformed one after another all over the world until almost everyone transformed, with the exception of a single person, the only person immune to the curse applied to Jen, Kyle.
