"...I want to play with her..." Erin's mind started screaming. Ty's face was softer and flushed with a bit of embarrassment as Erin was looking directly at... Well her now. Then her mouth said "No! you aren't Ok in your old clothes! If you can change your gender you should be able to change your clothes right?" Ty panicked looking at their clothes and feeling even more weird in her boyish clothes... She glanced to Erin, an- "NO! You aren't just copying my clothes! Come on use a little imagination how about a cute dress?" Through Ty's imagination her clothing morphed from Erin's shirt and tight jeans into a fluttering and somewhat long and frilly blue dress... Like literally fluttering as even without a breeze in Erin's home the edges near Ty's ankle's fluttered.
Erin kept looking at Ty and said "You've still got your guy cut, Try longer or more girly or something!" Ty's hair lengthened... he really didn't know how to do a girl hairdo so Ty just lengthened her hair longer which Erin seemed to accept but "You don't have a bra on do you?" Ty blushed a bit not really knowing much about bras or how they are made or how they were supposed to...
Erin had always wanted a little sister... maybe a younger sibling in general... but a little sister specifically. Someone to bond and share in mischief in such a way that she couldn't get with a maternal bond with her mom. Ty was a bit more like a little brother, but when she looked so much like a girl... Erin leaned over and pulled down her shirt's collar and asked "Why not copy mine?~~~" Ty's face got a shade or two redder although she did copy Erin's bra... along with her bra size. For as much as Ty had gained boobs they weren't like Erin's nice rack. The guy still in Ty was overstimulated... or maybe it was just all the reality alterations and she fainted a little. Erin caught Ty obviously and then noted... the bigger breasts... Erin... inspected them... just be be sure they weren't something weird or off... Then went on a way to get Ty back into the awoken world.
