Joe stood there with his sister standing before him. “Well I think I know where I want to start.” He said. “I already got breast balls and a breast dick.” He gently tapped his 2ft round breast balls.
Sarah hummed and nodded. “So?” She asked as she had her tail boob move.
“I want a breast tail like yours sis.” Sarah froze.
“Wait what? Really?!” She got all excited as she lit up.
That just made Joe raise an eyebrow. “Why so excited?” He asked.
“Cause we could because true twins!~” She beamed a huge smile as she wrapped a n arm around his neck. “Granted you would have breast balls and all.”
Joe looked his sis in the eyes. “But what about I need to look male?”
Sarah looked away in thought for a bit before she turn back and grinned. “Well good point. Then you just cannot have chest breasts. As I said. But other than that we should try to look the same.”
“Mmm but if I have a breast cock and balls you need a breast pussy.” He said which made Sarah freeze.
“No! I don’t need one!” She jumped back and swung her arms.
“But if I got these,” Joe pointed at his boobified privates. “Then you are going to get one.”
Sarah shook her head. “No.”
“It's not something you can say no too.” Sarah's brother said as he smirked. “So do we have a deal? And breastification we do to ourselves ust happen to the other. Excluding you will have a breast pussy instead of breast balls and boob cock. And I will not have breasts on my chest.”
Sarah broke, “Fine!” She threw up her hands. “But first you need to get the tail and then I'll get mine. And yes…. I'll make it 2ft round just to shut you up.”
Joe grinned, “Good to hear.” He the looked over his shoulder to point the gun at this tail bone. He pulled the trigger to feel the new breast body part form. Instantly he felt and saw it reach a soccer ball. And it only continued to grow. Groaning he felt the flesh multiplying fast while getting filled with milk.
He continued to hold the trigger, forcing the breast to go spherical. Grinning he watched the breast starting to take shape. It looked like a small version of Sarah's tail boob. ‘Halfway there.’ He thought.
Getting getty, Sarah grinded her hips as she watched the boob tail expand. Her eyes lit up as she watched it almost reached the same size.
“Perfect!” She jumped for joy.
Joe lowered his hand and let go of the trigger. He looked over his shoulders to see the matching tail tit.
Joe started to smile. “Huh this is weird but cool.” He spoke aloud. He turned and looked over to Sarah. “Now it is your turn.” He grinned.
Sarah sighed and slowly slipped her pants and panties off to let her sex be shown. She crossed her arms and blushed. “Just get it over with.” She said.
Her brother waisted no time to pull the trigger. Sarah felt a fire grow in her crotch as she looked down to watch it grow out. A budge of flesh grew out underneath her pussy folds. Quickly her sex’s inner tunnel stretched and then rounded out on the inside to form a giant pocket of air. At that point it was already the size of a beach ball with her nipple on the crotch tit replaced with giant pussy folds. She shuttered as she felt her sex touch the floor.
Joe soon let go of the trigger and smiled. “Good! It’s now the same size as Naomi.” He tapped his left ball tit. He heard Naomi giggle in his mind.
“Yeah….” Sarah droned as she looked at the giant sex that was between her legs. “Now…” She regained her mojo. “Go and choose what else you are going to breastifiy!”
