The twins were currently were working on some homework while there was something on in the background. The two half concentrating on both and thus not retaining much on either. Ty was watching the number on the oven increase for a moment as he thought "Coraline... if you were a guy no one would be able to tell..." Meanwhile back to the work/relax table Coraline was doing some math and then felt some strange feeling in her groin as somewhat started to snake out of her pussy.
"You alright Coraline?" Carla asked as she started noticing her sister's hair starting to shorten a little.
"I'm not sure..." Coraline said as she was looking down as a budge was forming then as she looked up towards Carla...
Ty thought "If only Carla were a bit more mature... like if she had any tits..." Carla wasn't wearing a dress, but a frilly pink shirt and some cute shorts. Coraline's sight was on Carla's chest a bit when her nipples starting poking through her shirt.
"What about you? Are you feeling cold?" Coraline asked as her voice was slightly deeper.
"What?" Carla asked and then felt a small bit of a pain in her chest and as she looked down she saw her nipples tenting her shirt. While she normally wouldn't do it she did peek into her shirt to see her nipples were growing. Not like hardening on a cold day, but actually growing! and her chest was pushing out bit by bit...
Ty thought "Maybe if Coraline had a giant dick and a beard you could tell he's a guy." Coraline's face felt all itchy as hairs sprouted, and her pants were getting too tight that she opened her fly and watched a mushroom like appendage pop out.
Ty thought "Also can't forget about having some nice junk in the trunk... Carla might be good with a few more years and some junk in the trunk." then heard some ripping as he exited the kitchen and walked in to see Carla hunched over with her ass in full display. The cute shorts having burst a seam to reveal some small panties wedged in her growing ass. It was a nice ass, and Ty could tell by looking at Clara's blushing face that she was steadily aging up... Still looking to Coraline who was looking a lot more masculine... at least in terms of her new penis and beard... Ty really needed to control his thoughts better... or did he?
