Luca selected his step-sis, and under her name he got some stats... Her age was a year under his plus a few months, she was obviously a female, straight... breast size: AA... Maybe she'd prefer...
Dawn was taking a leisurely stroll to her room when she felt a weird pressure in her chest, and then a constriction. She looked down to see her breasts actually forming! More than just buds were... The velcro training bra she had on snapped off easily as they grew and grew till they were DD's as her T-shirt rose up exposing her navel a bit. Dawn blushed a bit as she felt her new tits and wondered if she was daydreaming... and then the daydream ended as they started shrinking down. Not to nothing, but how did this... Dawn's mind wondered if Luca and that weird package had anything to do with this.
breast size: B... yep nice and existent, she was concerned about being nearly flat so she should like that. Luca thought that was a good place to leave it, he was feeling a little pervy with the first one. Then his door opened as Dawn came in "Was this your doing?!?!" as she had one arm around her chest mostly to support her old bra which may have been about to fall off without the support.
"Uh... yes? I thought since I had this you may have wanted... umm..." Luca tried thinking of something since the more he thought of it and with Dawn's reaction... Yeah this could be seen as kinda creepy
"Oh, that I wanted giant breasts?!?!" Dawn asked
"I was about to finalize it as a B, or maybe an A" Luca tried to defend himself against trying to perv over his little sister.
"Well fine do you know what I want? I-"
