Gwen reached down and grabbed the Yellow Breastinator surprising the twins.
“The Yellow one? Really?” Sarah wondered. “Isn't that a bit boring?”
“I think what my sister is asking is, why are you choosing this one, when the others can do that, too?” Joe said.
The goth carefully looked over the Breastinator from all sides. “Because boring is the safest choice here,” she explained monotonously. “It's my first time trying one of these things and I don't have any guarantee that they'll work as you said, if at all. I think some caution is acceptable.”
“If you're afraid, we can use it for you,” Sarah offered.
“Not necessary,” Gwen brushed them off. The twins sat down on their tail breasts and kept watching as the goth girl took off her shirt without any hesitation and pointed the Breastinator at her chest. She pulled the trigger and everyone stared at her right breast with great attention as it started to grow from A-cup over B and C until she stopped at D-cup. Gwen kept her monotonous expression as she felt her breast flesh expand and fill up.
The breast itself had a perfectly round shape, seemed firm enough that she wouldn't need a bra and were topped with perky nipples.
‘So apparently the Yellow Breastinator at least guarantees that the breast will have great quality, good to know,” Joe thought.
Gwen cupped her enlarged breast with one of her hands feeling the flesh between her fingers and some milk sloshing inside her tit, even starting to grope herself a bit. Even with the goth’s unchanging look both twins could see her fascination. “Wow.”
She aimed the Breastinator at her still small left breast and let it grow until it was a perfect clone of the right one. Despite being three cup sizes larger they still managed to look normal on her body. Fine for now with her D-cups she started fiddling around with the laser gun a bit more. “So you weren't born with these bodies?”
“No, the reality shift makes everyone believe it to always have been that way,” Joe answered. “Same goes for your new breasts. Well, in your case probably that they just normally grew to that size.”
“Then that means your mother…”
“Was zapped with the Pink Breastinator,” Sarah finished. “Same goes for Mss. Drake. My brother found out it also works with pictures.”
Gwen discovered the USB-cable of the Breastinator and the twins proceeded to show off that feature as well. The pale girl watched with rapt attention as they explained how to adjust settings and lock transformations.
“So there actually are girls living in your balls and dick?”
For a moment it looked like Joe was listening to something only he could hear. “They're saying ‘Hi’.”
Sarah excitedly jumped into a standing position. “So, Gwen, what do you want to try next?”
