"Hold on a sec" said Jenn.
Jackie tilted her head quizzicaly, in a very feline manner. "What, love?"
"Remember the last time we made love?"
Jackie thought hard. "Wait, we were, we were human? I remember something about us being human."
"Think harder." Jenn continued.
Jackie's eyes popped open. "I was male!" Suddenly memories came flooding back, as they had a few moments ago for Jenn.
"How the hell did this happen?" asked the football star turned catgirl.
Jenn told the story.
"So let me get this straight." Jackie's excellent mind was once again functioning at full speed. "This catgirl virus is 100% infectious, it always turns the victim female, and there are no cat-males. This moron is going to wipe out the human race to satisfy some idiot fetish."
"I guess." responded Jenn. "But if the curse works, don't I have the power now?"
The two lovers conferred for a few minutes.
+++++++
Despite the delicacy of their appearance, catgirls are stronger than human females of an equivalent mass, and they can move much more quickly than any human could dream of. Pudgy Kyle didn't stand a chance.
He smirked. "So it works? How do you like being a catgirl?"
"Shut up, moron." Jen spat out. She leaned over Kyle, pinned to the ground by the two catgirls, and breathed in his face. He was horrified when he realized what the catgirl had done, and mentally kicked himself for not specifying that he would be immune to the virus. It was working already, as hair began to cover his body and his flesh began to rearrange itself.
Jackie leaned over the prostrate changing Kyle. "In a minute" she purred "Jenn's going to tell you to Transform or Dare. You don't say anything, or I rip your throat out. That clear, catgirl?"
The terrified Kyle nodded his head.
"Transform or Dare?" asked Jenn.
After the minute passed in silence, Jenn began. "You transform to carry the anti-catgirl virus, which is 100% infectious on humans, but doesn't affect me" she turned briefly to Jackie, who nodded "or Jackie, or any other catgirl, including you. 90% of the humans who get it are unaffected except that they become immune from the catgirl virus, 100% for life. The other 10% are affected in that they have a fifty percent chance of turning male if exposed to the catgirl virus, and their sexuality, hetero or homo, will be the same as it was when they are human. I dare you not to use the transform or dare curse to transform anyone against their will, or to dare them to do anything they would not do of their own free will."
Jenn and Jackie stood up, and Kyle did more slowly, still terrified of what the catgirl pair would do to him. "Now" said Jenn "Mingle."
