"Not in the slightest!" Nikki grouched.
"Fine, fine, I won't do anything more to you, but why not keep the tail for a while, just for kicks?" Jessica cajoled as she scrolled through the myriad of Chronivac options. "Hey, look, it says there's even a way to make everyone think the changes are normal, so no one thinks it's weird!"
"What, you want to mess with the whole world, now??" Nikki's eyes narrowed. However, Jessica was too excited to notice.
"It's even got options for how normal you want to be...'Worldwide phenomenon'...'Genetic anomaly'...'Magical curse'...'Tacit acceptance'...hey, that one makes everyone take it as normal without even wanting an explanation! And an "Awareness" option..." Jessica trailed off as she fiddled with the controls. What would be the fun of not being aware you changed everything? And Nikki should be aware too, otherwise she'd never believe it...
"Are you listening to me? This is way too risky--" Nikki tried to jump in.
"This should do it!" Jessica exclaimed as she hit the "Confirm Changes" button.
"Do what??" Nikki snapped, but before either of them could say any more, both felt an influx of new memories pouring into their heads. No, not entirely new memories, everything was similar to their original memories, except for one slightly significant detail.
"Why...do I remember always having a tail?" Nikki gasped. "But I never had a tail!"
"IT WORKED!" Jessica chortled as she jumped up, her tail curled in glee. Before Nikki could say anything, Jessica reached for an album where there were pictures of her and Nikki as teenagers. Sure enough, there was a shot of she and Nikki at the beach in bathing suits, only now, poking out of the back of each suit were their respective tails. Nikki's tail was even braided for convenience.
Jessica then opened her closet and pulled out a pair of pants. Sure enough, there was what looked like a small fly at the back, a handy opening just for her tail.
"See, now you don't have to worry!" Jessica grinned from ear to ear. "No one will even look twice! Now we can see what this baby can really do!"
"You crazy--" Nikki gritted her teeth.
