"Hmmm..." Jessica pondered, then remembered what she said about her tail. She could give herself another such tail, or...
"I got it!" Jessica grinned as Nikki looked on warily, then began typing in her selections.
"What are you going to do?" Nikki asked suspiciously. Jessica completed her options, then leaned back in the chair.
"Why settle for one extra 'hand' when you could have more?" Jessica smiled, then said, "Ooh!" as the changes began.
Nikki saw Jessica roll her shoulders as if they were stiff, and suddenly they looked slightly larger, almost as though they were swelling. Jessica's armholes seemed to widen, then came the interesting part. Each shirt armhole split into two holes, one above the other, and while Jessica's arms were extended through the top holes, a strange lump of flesh was gradually growing out each bottom hole. The lump got longer, then more defined, and eventually, Jessica looked with wonder as instead of having one pair of arms, she now had two, each with its own hand.
"You gave yourself...two more arms??!" Nikki gaped. "How do you expect to hide that??!"
"Why would I hide it?" Jessica asked in wonderment as she flexed each arm individually, getting used to the process of moving one hand at a time, not to mention each of her now twenty fingers. "I can just make it seem normal."
"You're not going to mess with my head again??!" Nikki protested.
"Hmm? Oh, don't worry, I'll leave your original memories intact, just let everyone else think it's the norm," Jessica replied, still slightly distracted as she used two of her hands to type into the Chronivac, while her other two hands unwrapped a candy.
Nikki stared as the pictures around her changed, all the images of Jessica now having four arms total, not to mention her tail. She wasn't sure how she felt about reality shifting over and over at Jessica's mercy. That didn't mean she wanted to change it herself, but Jessica seemed way too nonchalant about all this.
"Sure you don't want a turn?" Jessica asked absently as one hand popped the unwrapped candy in her mouth while the other picked up her phone, her two remaining hands still scrolling through the Chronivac.
