“Before you go sis I want to show something to you,” You said.
Crossing her arms she spoke up, “What is it?”
Picking up the gun you walked over to hand her the Breastinator. “I found this online and bought it. I mostly got this because I thought it would be a funny toy to hold onto.” HE also gave her the instructions let her hold the gun and read the instructions. “I doubt it actually works but if it does it’ll be kind of funny.”
“You are a dumbass,” She deadpanned. She handed you the instructions. “Like this will actually make breasts grow anywhere!” She shook her head.
“Then why don’t you prove it?” You baited her.
“Alright then!” She retorted “I will!” She stepped through your door and then closed it to have just you and your sister along in the room. SHE then took off her white shirt to show over her white bra. Hitting to grow button on she pointed to her back. Sara took aim at right above her butt cheek at her tail bone. “If this works then....” She paused. “Then I will keep this new breast that I will grow,” she sarcastically laughed.
You held back a laugh and smile as you then added to the bet. “Alright, if it does work you’ll make it at least the size of a beach ball.”
Sara then added more. “Then If it doesn’t and it won’t. Then we will get rid of this toy and forget that this ever happened.” You agreed and watched as she pulled the trigger. Alien, the familiar feeling of a breast grew out right at her tailbone over her butt crack.
She turned her head to watch as a nipple grow out as a new round flesh followed out. She continued to hold the gun’s trigger as a brand new breast grew out. Her face fell as he let the new breast hit the triple D size. Her hand shook as she finished growing out the breast to let go of the gun and let it drop once her new breast hit the size of a beach ball.
She reached down to grab her new bouncy breast and gasped quietly as she grouped herself. “I can’t believe it!”
You broke into a smile and walked up to pick up the gun. “Looks like it work!” You laughed. “SO I guess that mean you are going to have to keep your new breast!”
“No please let me get rid of it!” Your twin panicked as she pleaded.
You shook your head and then walked over to your tall drawer to place the gun on the top. “Nope a deals a deal right?”
Weakly she nodded as she shook while putting her white shirt back on. “Fine,” she grumbled. “But I want to be able to play with it later tonight.”
You agreed. “Sure, later tonight when everyone else is asleep.”
