"....and.... this should-" Jeff was saying when
"SHOULD?!?! That thing changes reality and is about to do something to me!" Jenny said still having Jeff's blanket over her now voluptuous form and tattered/tight clothing.
"Your clothes..."
"Close enough!"
"Listen this setting on the Chronivac should adjust your clothing... So let's do this and that and..." *click* went a key and Jenny felt the tightness from the bits of fabric that hadn't given up yet, and the looseness of the fabric that was long gone fade as her clothes refit her body. She pulled the sheets down to get a better look at her enhanced body now clothed and...
"These... aren't D-cups..." Jenny said as she was looking down at a Canyon of flesh somewhat corralled by a tight belly shirt. Jeff looked over and his girlfriend was now very... fleshy lets say. Her ass wasn't that much more fleshy relative wise as it was more stretched over wider hips bones, but a rather large C-cup worth of flesh was added ontop of Jenny's new D's, and of course her soft belly now started to get a bit pudgy.
Jeff looked at the chronivac and said "So that's a redo button?" and pushed it again and now that Jenny wasn't focused on ill fitting clothing she could feel the chronivac's force on her body expanding her clothes and more importantly her body. The type of bra she had been wearing was not the right type for... whatever size the suckers were that were now drooping off her chest. Jeff saw his girlfriend try to stand up properly and move with her absurdly large hips, and now fat gut. Each step her hips swayed exaggeratedly as she held out her hand.
"My time to play with your body."
"But it was your change..." Jeff tried to complain meekly.
"Maybe the first time, second time I can accept as a mistake, third and I gotta get some revenge." Jeff let Jenny use the chronivac and he was bracing for some sort of impact unsure of how she'd try to mess with him.
