Sarah looked down at her extended pussy, 'Now this feels really good!' She squealed in the back of her mind. She reached down to her trembling pussy. 'I wonder, if it is supposed to grow a breast underneath a needed organ like an eye then why didn't transform my brother's balls into a breast ball hybrid? If he indeed used it on his own nuts then he should have grown a pair of breasts on top of them.' Sarah shook her head and then pulled her new pussy breast. She them starred at the sight. "Perhaps if I can grow a pussy breast and make hybrid breast body parts..." She trailed off. "That maybe I can grow a breast inside of a body part." She grinned.
Using her left hand and arm she held the extended pussy up so she could see the opening. Using her right hand with the Breastinator she put the end of the gun into her pussy lips before she pulled the trigger.
Instantly she felt a very weird feeling as she could feel a new ball grow on the inside. Right then her pussy breast grew and widened as a new breasts grew inside of her pussy breast. In minutes she saw a new pink nipple poke out through her pussy. Still holding onto the trigger She moaned and closed her eyes. Holding onto the gun fro an unknown amount of time she finally let go of the gun's trigger. She moved her shaking hands to gently toss the Breastinator onto her bed.
Opening her eye she looked down and gasped at the sight. Her pussy breast was the same size but her pussy was stretched out to let her internal breast stick out. Her new breast was about the size of a large beach ball and it was a foot and a half round and was three feet long.
'This is perfect!' Sarah thought as she gentley stroked her new breast. 'Alright, now what she I do?'
