You wait as Naomi tried to figure out what she wanted to do. Yet as you waited her eyes kept shifting back at your balls. "Alright take off your shorts and underwear I know what I want to do."
You blushed slight and asked, "Wait a minute you want to change something about my privates?" You said as you realized what she might be going for.
"If it can make breasts grow on any living thing then it has to be able to make them grow and shrink as well right?" She skeptically asked.
You nodded as you slipped off your black shorts and white underwear to leave your breast balls hanging naked. "Yes the Breastinator can," You truthfully replied.
After looking at the gun she hit grow option on the breastinator and then aimed at both of your breast balls before she pulled the trigger. An invisible beam hit both of your breasts to make them grow at the same time at a good steady pace. Naomi's mouth dropped as she watched your nut grow out to hit hit a two foot round state as they grew out. She kept holding the trigger shaking as she saw your breast hit the two foot six inches round size. At that point you were on your knees moaning slightly. She quickly let go of the trigger to have the stop at three feet round. "I can't believe it!"
Collecting yourself you stood up with your breast ball being half as tall as you. "Why the hell did you make them so damn huge?"
Naomi dropped the gun and slow walked over and touch your breast balls. This made you moan and fall over onto them. "I didn't expect it to work nor did I mean to make them grow this large!" She exclaimed as she gently gripped your soft breast flash. With every movement of her fingers she made you gasp slightly. "However I don't think I mind that they are this big now." She smiled. "But why the hell did you get this gun and tried to use it on your own nuts?"
You looked straight at your girlfriend. "I thought it was a prank and never thought that it would work." You truthfully answered.
Nodding Naomi stood up and let go of your now insanely massive privates and picked up the gun, "So..." She started as she looked at the gun. "I have one request." She stated as she then looked up straight into your eyes. Unlike you she was a foot shorting than you as you were right around six feet tall.
After a minute you managed to stop moaning as you got yourself upright. At this point you were still half naked and was only covered by your long sleeve dark green shirt. "Sure what is it?"
Naomi went red in embarrassment as she asked, "Can you keep your breast balls at this size for a while? I'm actually turned on at the sight."
Your mouth dropped as you gasped. "Seriously?"
She weakly nodded. "Just for a while," she truthfully spoke. "We can turn them back to their normal size."
You nodded. "Alright, I guess after a bit we can make them a normal pair of nuts."
Naomi shook her head, "Max. From what you told me you shifted reality where you always had breasts for balls." She stopped to let it shrink in. "For me you having breasts for balls that reach halfway past your knees is normal. So please, if we shrink them down. Let me make them that size again."
Sighing you nodded and walked a bit off to her right and put a hand on her shoulder. "Alright, if we shrink my breast balls. Then they return back to that size."
Naomi thanked Max as she said, "Arigato."
You smiled and brought up, "Although carrying these are a bit heavy as I think that they are stuffed full will milk." You stammered and went red.
Her eyes widened and she went red. "O- ok. What now?"
You started to think, "Well first take a look at the instructions." You said as you pointed to your desk where the paper of instructions laid.
Naomi nodded and picked up to paper and read the instructions. "Max, i don't want you to put breasts too close to your dick." She looked concerned as she looked straight at you. "I do not want my boyfriend to become a girlfriend."
You then figured out what she meant. "Alright," you agreed with her. "But why?"
With hands on the hip she spoke out. "I don't mind if you get more breasts but I still want a guy as my partner so unless we can figured out how to prevent you from transforming into a girl. Then I don't want to give you any more breasts other than just making your breast balls bigger or smaller."
Smiling you spoke up, "Makes sense but now that you believe me. Do you want to use the Breastinator or do something else?"
Naomi closed her eyes in thought before she opened them while she had her arms crossed. "Alright I think I know what I want to do." She said.
