Dance, The

Once I was going with girl named Jenny, she was real nice and she had an awesome body, her breasts were pretty big and round, but her ass was huge! She was known through out the school for having an extremely large butt. And Jenny liked it too, she always wore the tightest pants and always bent over in front of people. For her gym class she would wear spandex bike shorts and no panties, so she could show off her ass. Jenny's butt was so big that she could barely fit into the desks at school.

One day she wore a long, front button up dress, it was pretty loose, but you could still see her huge butt shaking inside when she walked. under that she had on a tight pink shirt, some jeans over her gym shorts. she had dressed up for the dance and she wouldn't be able to go change in between the dance and the end of school.

Me and Jenny had agreed to get out of class and meet in the empty science lab. when I got to the lab she was already there. I walked up to her and wrapped my arms around her, and she did the same to me. I undid some of the buttons on her full body dress around her stomach, and slipped my hands in side and placed them on her butt, one on each cheek and squeezed gently.

"Ooh- I missed you" she said,and we began kissing. I put one of my hands between Jenny's legs and tickled her crotch, she squeezed me and giggled. Jenny made the cutest sound when she giggled "AH-DIZ- AH-DI-DI-DIZ" and she would shake her butt, it was almost like she was going to sneeze.

She had slot of little cute things that she did to turn me on. One thing is, she would back up against me bending over and pin me with her huge ass. Then she would wriggle it and sometimes fart, I loved it when she farted.

"Is my butt too big?" she asked.

"No way! I love your big butt, that's one of your best assets."

"Yea, but its sorta hard to manage...sometimes I knock things off shelves when I walk by its so big, and it knocks over desks sometimes too. And I bump it to people in the halls, and I always have to be careful when I turn around fast. I also have the hugest panty line in the school, I get stuck in places too!"

I paused and said, "Your butt is the best looking in the entire school, trust me its worth the trouble, so please don't try and get rid of it."

She though and said, "Alright I won't." With that we went back to class.

We met at the dance that night, and she was hot, she had on what she had on before, the navy blue dress, that went past her knees and showed off her tits and her immense ass.

"Hey Jenny, how are you?"

"Alright I guess, I feel funny though, and my ass tingles."

Near the middle of the dance, me and Jenny had just finished slow dancing, some accordion stuff came on and everyone got into close lines and began rhythmically clapping and swinging each other around.

I put my arms around Jenny and swung her, while she giggled. Then she got in front of me and everyone stomped to the rhythm, Jenny's huge butt was shaking tremendously, it kind of jiggled to the music. I moved closer to her and put my arms around her waist. Her ass was pushed up against my crotch, shaking my c--- the girls stopped stomping and began clapping again.Jenny giggled, with her back to me and made a little noise," AAH-DIIZ!" like she was about to sneeze, and her ass shook a little. I continued admiring her body when it happened again, this time more frantic" AAH-DI-DI-DIZ" and her butt shook more.

I tapped her on the shoulder and asked her what was happening, she said "I don't know but it really tickles!" It happened again and Jenny grabbed her butt and crotch and giggled. She opened up her dress to find out what was happening, and looked down her lower body , mostly her ass, was getting bigger. Her hips were widening, her thighs were growing,her calves were swelling, her crotch was getting tighter and her butt was getting huge!

Jenny gasped and quickly closed her dress and redid all the buttons before anyone could see. She turned to me and said," I think I'm going to fart!" The noises kept coming. "AAH-DIZ, AAHH-DIZZOO!" and her ass continued to balloon.Jenny's dress kept getting tighter and tighter, the noises were coming from her inflating butt. People began turning around and noticing Jenny. Her dress became very tight around her, the buttons were straining to hold in her gigantic ass.

"OOH- this is so embarrassing!" Jenny said in between giggles, while she tried to hold her dress together. I wanted to help her, although I did like seeing her like this, just not in front of every one.

I rushed her towards the door, but her hips were to big to go through, and her butt was to big to turn side ways. Jenny took a step back from the door and grabbed her butt, in a desperate attempt to keep it from growing more. Her dress was bursting at the seams, people continued to watch as the sound of stretching fabric came from Jenny's butt. You could see a little of Jenny's jeans through the stretching seams on her dress.

Then Jenny's top button popped off and sailed across the room. Then the next did the same, now you could see her tits that were only covered up by a tight white t-shirt.then the rest of the buttons burst off in rapid succession, making Jenny's lower body jiggle a little.

Jenny's ass was just barely confined by her stretching jeans. Her butt was about the size two very large beach balls and her hips were about 3 1/2 feet across, and her butt wasn't slowing down.

Everyone's attention was on Jenny.

"Her butt is huge!"

"Its getting bigger!"

"She's gonna pop!"

"OOH- it tickles, I think I'm going to fart, I can't hold it! My butt's too big!" the button on Jenny's jeans popped off and she was holding the zipper together, then the seam on her humongous butt crack began to rip, then the jeans exploded off her leaving Jenny in her spandex gym shorts.

The noise was very frantic now and still coming from Jenny's ass, as she was tickled by the air expanding inside her butt, her ass was about 6 feet thick and 7 feet across.

"MY-UUH- BUTTS GONNA BLOW! OOH- I CAN'T HOLD IT! I'M TOO BIG !" Jenny yelled, she seemed like she was trying not to have an orgasm from the tickling. If she climaxed she would surly blow. People turned over tables and chairs to get away from the blast.

"IT'S COMING!" Jenny yelled and grabbed her crotch. Her butt began rumbling and Jenny screamed-

"OH-OOHH-OOOHHH-OOOOOOHHHHHH-" she was climaxing, her butt was gonna explode! "OOOOOOOOOHHHHHHHHH-OOOOUUUUUUAAAAAAAHH!"

"KKKKKKKKAAAAAAAAAABBBBBBBOOOOOOOMMMMMM!"
