John couldn't believe it but he actually made it. But for some reason, there were only stalls, and he was sure he went into the mens room.
"Weird" he thought as he entered a stall and locked the door behind him. After he unzipped his pants a big, fat, dick burst out. "Must because of all the pressure" John thought. But when he released, nothing came out. "Huh?" John thought, "this is definitely weird." Then all of a sudden he felt funny - his dick swelled in his hand and he started to hear a hissing sound.
"Finally", he thought, looking down. Then he did a double take. There was no pee. It felt like he was pissing, but nothing was coming out. Nothing he could see, at least. As the pressure released from his bladder and stomach, John felt himself relaxing, and lifting off the floor! He looked down and realized the hissing was coming from him, he was leaking gas and it was getting stronger. Before John had a chance to brace himself, the force of his air stream lifted him off the floor, propelling him up into the corner of the bathroom.
"What the HEEEEE-----??!?!" John shouted as he was bounced off the ceiling and rocketed around the room, hitting the walls, bouncing off again, spiralling like crazy as he lost pressure like a balloon that had been untied. Luckily, his body seemed to take on the feeling of being a balloon, so as he hit the walls it didn't hurt. He simply bounced to the next surface, yelling the whole time and getting dizzier by the second.
After what seemed like hours he felt himself come to rest on a cold hard surface. John laid there for a moment, trying to make sure that gravity had come back and that he was actually 'down'. "Man," he heard a squeaky voice say, "what a rush!" Then he caught is breath. He had said that! What had happened to his voice? It sounded like he'd been breathing helium! Had he really become a balloon?
John got up off the floor, felt himself his chest and legs, all back to his normal musclar build. He turned around, trying to see if a string had been tied to his ass, some sign that he'd been changed into a balloon. No strings attached. Whew!
He was all back to normal, for the most part. His clothes hadn't survived as well as he had. His extra girth from the nachos had stretched out his shirt pretty badly. It hung loosely on his chest. His pants too. They seemed to have stretched all out of shape. They hung on him, revealing a good 3" of his baggy boxers. He tugged them up to his waist, trying to adjust himself. His jeans were too stretched out to be easily managed though. They were covering his feet.
Wait a minute... John looked himself over. His clothes were BIG, big and long. Much more so than could be explained by just the stretching a big gut would bring on. As he looked at himself, John realized he must look like his own kid brother, dressing up in clothes that were 5 sizes too big for him. He looked around the bathroom, suddenly realizing that the room had stretched out of proportion as well - the doorknob was now up to midchest on him.
He approached it gingerly, afraid to touch the knob with his small hands. Using both hands, he opened the door and walked out into the locker room. It was gigantic! Easily twice it's normal size! What had happened to him?
Just as he was figuring it out, John heard voices, loud and gruff coming down the hall into the locker room. He looked up and saw...
