“I think I got an idea,” My sister stated.
“What’s your idea?” I asked with crossed arms.
“Soda Breast, Cherry Coke filled.” My sister smiled before she started to tinker with the gun and pulled the growth trigger as she aimed at her chest. I blinked as I watched her breasts grow bigger. Fairly quickly, she smiled as her breasts broke out to hit the C cups from her normal B range. I watched both grow out even farther as they rounded out to more spheres defying normal physics’. At that point they broke past the E range as they hit the size of a basketball.
Quickly she let go of the trigger to stop growing her breasts, "Ah the perfect size." My sister gleamed.
“Glad you like that size,” I told her. “But did you make them lactate Cherry Coke?”
“Not yet,” My sister told me. “I am just about to do that.” Sarah smiled. She opened the gun's side menu and to her and my surprise. A slot opened as a small keyboard generated out underneath a new screen that extruded out from the right side of the gun. After she looked through the simple menus she went down to the setting in the gun for lactation. “Looks like I found the option.” She told me. After she did a few more tinkering with the gun she smiled. “This should work.” Sarah then hit enter on the guns key pad. After she did that the keyboard and screen folded back into the gun to hide away.
After she was messing around with the gun, my sister finally took aim at her newly created basketball breasts and pulled the trigger to set whatever new settings, she put together. Tossing me the gun to catch she shook her breasts a bit.
“Did it work,” I asked my sister.
She nodded as she beamed a grin at me. “Damn right it did Joe."
I then turned and looked at the other Breastinators and started to think. “Well now what else can we do?”
My sister looked at me before her eyes shifted to the other Breastinators on my desk.
