Joy sat on a couch in her apartment with her 2 best buds Calem and Heather. Joy was a short, flat, spectacled nerd who often had her nose in her phone. Heather was Joy's roommate and childhood friend who was a streamer that often made enough tips through... her.... personality... Although right now she was dressed more conservatively with Calem around. The other childhood friend who lived in a different apartment due to being a guy, but the three had grown up together and enjoyed each other's company.
As an ad started playing on the tv Calem got up and stretched and said "Gonna take a piss. Want me to get you soda's while I'm up?"
"Dr. Pepper after you've washed your hands Calem." Heather said meanwhile Joy asked for a coke. That was when Joy had finished setting up her Chronivac account. "The heck you got there?" Heather asked
"Some app some people online call a Chronivac. It apparently lets you change living things... Just set up my user account and now... Ah, I scanned you and me and we have soul accounts in this?" Joy clicked to see her soul account and saw a number of different possible changes.
Heather chuckled and said "Sounds like some weird app or scamware."
"Had my antiviruses take a look at it, and it seems clean." Joy said as she saw a boob size editor on her soul account and casually glanced to Heather wondering what it was like to have big boobs.
"Well what are you gonna chan-" then Heather heard clasps breaking and buttons popping as the girl next to her suddenly sprouted boobs the size of bean bags. Both girls eyes went wide. Heather held a finger up to her lips and then whispered "Quick do me next and then when Calem comes out..."
Calem washed his hands wondering how much of the show he missed as it felt like he pushed out a gallon out of his bladder. Walking out of the bathroom Calem started to go to the kitchen until he saw some pale fleshy mounds in the corner of his eye where his best friends were... Then turned to see giant boobs attached to them and asked "Wha?!?" Confused and slightly aroused Calem's member erected a bit.
"Ew..." Heather said playfully but also slightly erotically and continued "Joy could you do something about his boner?" Calem was unsure of where this was going until Joy pressed a few buttons and then his wiener dug itself a hole into his body as he shrank a foot then some C-cup breasts formed on his chest. Of course a lot more happened, but Calem was panicking as one hand went to his groin as the other cupped his breasts examining some massive changes to his body.
"Holy Shit that actually worked!" Joy exclaimed.
"The Fuck is going on?!?" Calem yelled in her high pitched voice
Joy chuckled and said "I have an app that lets me change living things around me."
"Change me back!" Calem demanded as Heather chuckled.
Heather in an ASMR-like voice asked "You sure you want that? We're all girls now. We can have a bit of skinship." Then she lightly tapped one of her massive breasts and loudly whispered "Lots of booba to go around~~" Calem was frozen in confusion and horniness for a bit as Joy thought about what they should be doing next.
