Jenny ran in the door to her room, shut it, and locked it. She was over- excited and couldn't wait to try her new bra out. She pulled a small box out of her purse and threw it on the bed. She then pulled her shirt off over her B-Cup breasts and long black hair. She than undid her bra and threw it across the room. Her breasts bounced a little as she opened the box and sat down on the bed. Inside was a light blue bra covered by balloons.
Jenny has always loved balloons. She likes to blow them up, pop them, stick them in her shirt over her breasts, or just bounce on them.
She giggled and pulled it out. Under it was a beige colored bra and a instruction card. She read the card. It said: 1: Put the beige colored bra on first. She took it out and placed it on. She snapped it in the back and then looked back at the card. 2: Put the balloon bra on. She grabbed the bra and she was about to put it on when she noticed the beige bra had disappeared. She felt her breasts and noticed that they seemed a little rubbery than before.
"Must've just blended in with my breasts." She said to herself snapping the bra on.
The bra fit her chest perfectly. Back to the card. 3: Attach air pump to the nozzle on the back of the bra (Have a couple of extra balloons ready in case if one pops. Jenny reached under her bed and brought out a bag of Extra Large Balloons. She took out a red one and blew it up till it was 18". She hugged the red balloon and BANG! It popped. Knowing this, she went to her closet and brought out her air pump. She connected it and turned it on. She looked down to see the balloons on the bra inflating. She went back to the card. 4: Popping will not harm the breasts. And it said no more.
"Popping the balloons wouldn't hurt them anyway." She said.
She then watched the balloons on her bra expand until she thought they were big enough. She turned the compressor and went over to her mirror. She was delighted that she actually was wearing balloons. She even felt like she had air in her chest. Then she noticed that the balloons looked a little smaller than before.
"Must be a leak." She said gently putting her arms around them.
Now she heard a sound like a hiss. No. More of a hiss like when you blow up a balloon. She looked down again to see that her breasts were expanding as the balloons were deflating.
Her eyes grew wide as she watched her B-Cup breasts turn into over-inflated basketballs. The balloons were empty and she squeezed them to make sure. She giggled at the fact that now she had her dream: Huge tits! She laid down on the bed and took off the bra. Her breasts were real all right. Her breasts felt rubbery and gave a faint squeek at she rubbed them. She flipped herself over and bounced on them a bit. She laughed as her tits bounced her on the bed. She stopped and started inspectng the balloon bra. She turned it over and saw a plastic piece where her nipples fit in.
Then Jenny got an idea. She reconnected the pump and turned it on. The bra's balloons again inflated. She disconnected and put a finger over on of the holes to see if she was right. The balloons deflated and she felt a stream of air come through the holes.
"That's why." She said in amazement. "Wonder how big they could get." She placed the bra on and pumped the balloons back up. She disconnected it and waited for something to happen. But nothing did. She pumped up the balloons more, but they all popped scattering colored rubber all around her room.
She thought for a minute and then her nipples popped out. She got an idea. Jenny took the bra off and placed the hose to her right nipple. She turned it on and the breast swelled up to twice it's size, then it stopped. She didn't know why, but it felt really good. She placed it in her other and did the same until it stopped. She squeezed them and giggled again. She never felt this good in her life. Now she felt like popping them. It wouldn't inflate any more through the nipple, so she placed it in her mouth, turned it on, and inhaled. Instantly instead of her breasts getting larger, her belly bulged out expanding to the point where it was the same size as her breasts. Then she felt vibrating. She wanted more air. And she felt that they were gonna pop when she started rising from her seat. She looked behind to see that her butt was inflating too. She managed to take her jeans off before they grew too big. She then pulled her panties down under her inflating ass. They too reached the size as the others. She then closed her eyes as they became a little transparent. Then BANG. She opened her eyes and couldn't believe what she saw. Her belly button popped out and was also inflating. She looked up at her breasts and saw that her nipples were ballooning up as well. She then felt the vibrations again and then she heard a soft pop.
She opened her eyes to see that her body was normal again. She looked around and saw no sign of the popped breasts or belly or her butt. She put the balloons back on the bra and proceeded to do it again.
