"Yes! Finally done!" Sarah let out a long laugh. It was the last day of the semester, and she was going to celebrate. College had been tough, but now that the first part was over, she was going to get so wasted that she'd forget her own name. She let out another laugh. Sarah was tall, almost 5'11", and she had straight black hair and very green eyes. She was thin, not bony thin, but healthy. She had a few curves, but nothing to turn heads. Sometimes she was depressed that she didn't have more in the chest department, but today, she wasn't thinking about it at all. Quickly dressing in a almost skin-tight black pants, and a maroon tank-top, she quickly left her dorm to hit the town.
As far as she knew, everyone who was anyone was going to this new club. Sarah didn't know the name, and in fact, no one she asked did. They knew what it was, and where, just not the name. It took about 5 minutes to walk to the club, and when she was 2 blocks away, she could feel the bass line of the music. The club looked almost dirty when she go to it. There was a moment of confusion, and then, with a smile, she pushed open the doors and walked into the thrall of people.
"Hey Sarah! Over here!" she turned to the voice and saw her good friend Casey waving to her. Sarah quickly walked over to her. "Say, Nice pants. Or did you just paint your legs?" Casey laughed. "Here ya go, sit down. We're just starting. It's your round."
Sarah smiled and quickly took a drink. "Ok," Sarah said. "That's one!"
Many hours later, the party was beginning to reach it's peak. "What number are we on?" Sarah asked sluggishly. "I dunno, I lost it in the teens." Casey said, giggling. "Oh, Look!" Sarah turned to where Casey was pointing and saw a large number of people taking hits off of a helium tank, and laughing in their high pitched voices. "Heheh! Come on Sarah! Let's take a hit!" She laughed and began to drag Sarah to the tanks. "Here, I'll make it interesting. I'll bet that I can tae a larger hit then you. I got five dollars, What do you say?" Sarah laughed in her drunken state. "OK, deal!" Casey smiled and took the hose. Carefully, Casey took a deep breath of the air, and then preceded to sing Jingle Bells in her high-pitched voice. "Heehaw!" Casey said. "Beat that!" Sarah smiled and staggered up to the tank. By this point, they were starting to gather a crowd. Sarah could hear them whisper, making side bets. Sarah grinned and stuck the hose in her mouth. She then gave the nozzle a quick turn and inhaled deeply. She could feel the gas rushing into her, filling her lungs. Sarah then tuned off the helium and began to recite poetry. But in the back of Sarah's mind, she felt something was wrong. Her pants, tight before, were now almost cutting into her hips. She quickly forgot about it, and finished her speech of "Casey at Bat" She was feeling a little lightheaded, and stepped down off the stage.
Sarah turned back and saw Casey preparing to take another hit of the gas. Sarah smiled and crossed her arms. She paused then, because it had taken more effort to cross her arms then, almost like something was blocking her arms. Sarah looked down at her chest and gasped in surprise. Her breasts had grown! They were almost a cup size bigger!. Sarah looked down at the rest of her body, and she was pretty sure that her butt was bigger, and it looked like her belly was bulging out a bit as well.
"Hey! Sarah! Your turn! Or have you had enough already?" Casey laughed with her high pitched voice. Sarah let out a high giggle, and ran towards the stage. She grabbed the hose and turned to Casey. "I'm doing fine. But after this, you won't be!" She stuck the hose in her mouth and turned the nozzle on as high as it could go. Sarah's eyes bulged out a little as the handle broke off in her hand. But she soon had more pressing matters, as she was beginning to grow bigger! She looked down and could see her breasts beginning to expand outwards. Sarah could also see her belly growing larger as well. And her pants were very quickly on the way to ripping off of her inflating butt. Surprisingly, Sarah didn't feel bad about this. In fact, she felt very good. Also, no one else in the bar seemed to mind as well. They were all laughing and watching her blow up. Sarah's breasts were now stretching the tank top to the limits, and her pants were becoming far, far too tight. Sarah began to try to take them off, but stopped when the seams along the side ripped and fell of her body. Her shirt was beginning to rip as well, and soon, it tore open, and her breasts, now the size of small beachballs, floated in front of her. Sarah squeezed them gently. They felt like large balloons, and were acting like them too. She could feel her breasts pulling her up very slightly. Sarah could also feel her belly growing larger and larger, and it soon looked like she has swallowed a few basketballs. Sarah rubber her huge balloon belly and moaned in pleasure. It felt so good! But Sarah was having more and more trouble bending her arms. She looked at them, and was shocked to notice that they were swelling up as well! Her arms and legs were sticking out from her body, and they were swelling up. Sarah's body was swelling up as well, slowly becoming spherical. She felt her body getting larger and larger as the gas rushed in. Soon, Sarah was almost 7 feet around, and the only things that made her look human were her hands, feet and head. But suddenly, Sarah was jolted out of her pleasure by a slight feeling of pressure in her body. Sarah looked down at her huge body, and saw that she had stopped growing, but the gas was still flowing in. Sarah's eyes got wide and she felt the pressure rise in her massive body. The pressure got higher and higher, as Sarah was pushed closer and closer to climax. Soon, Sarah's body was quivering with the pressure, and with the impending climax of Sarah. Then, suddenly, two things happened. First, the tank ran out of helium, and the gas flow stopped. Second, with a cry of pleasure, Sarah climaxed with explosive force. All of the gas rushed out of her, pushing her backwards off the stage. Sarah lay on the ground, naked and panting, watching her body slowly shrink back to normal size.
"Come on, Balloon girl!" Casey yelled at her. "We need to get you home!" Casey draped her coat over Sarah's body, and they ran out the back door.
The next day, Sarah read a article that the new nightclub had been recently shut down, because the owners were releasing hallucinatory drugs into the air, to get people to come back to the club to increase business. The managers had denied doing this, but there had been reports of mass hallucinations, involving a inflating unidentified woman. "Did ya see that? You're a hallucination! I wonder if that makes me a skistofrentic..." Casey sat down next to Sarah. Sarah laughed. "It's weird Casey. It felt so good blowing up, but I don't know what do about it!" "Well, gym at school's locked up, and I have a key copy. Also, If I remember correctly, there's still a bunch of helium tanks left over from the last dance."
Sarah smiled. "Well, why didn't you say do before?" With what, Sarah jumped up, and started to run over to the gym. "Oh, by the way, you still owe me that 5 dollars."
