I was at the local swimming pool wearing my new one piece bathingsuit.
At one point I suddenly noticed a rather strong urge to poop come up.
I was having too much fun in the water to leave for the toilet right now, so I decided to hold it in just a little longer. But this urgent need didn't go away.

Finally when it started to get painful, I decided to go to the bathroom. I needed to go so bad by now that I doubted I would make it on time.
When I got out of the water the urge even intesified. I pressed both of my hands on my bum and made my way to the bathroom as fast as I could without running as I didn't eant to slip and fall because I would surely lose it then.

However. I made it to the womens restroom without any accident but there was some creepy guy in it, doing some kind of plumbing job, or so. I was almost in tears by now. Though I didn't dare to do my business while he was in there. So I turned and made my way towards the only other womens restroom at the opposite end of the venue, hoping against hope I would make it.

I had already made it half the way when suddenly the poop decided that I wanted to come out. I managed to stop it but not before I had little ball of poop settling in my butt crack. Sweat and tears were running down my face by now.

I made it to the other restroom without any further accidents.
Just as I entered the poop started coming out again. Dumb as I was, I stood still and tried to regain control. But I couldn't get it to stop.
And there was a lot as I hadn't been for a poop in over a week.
I felt how the warm mass filled my entire ass crack and began to spread over my butt cheeks. Then it started to creep on forward between my legs

I suddenly heard voices aproaching. So I went into the farthest stall - still pooping - and locked the door. By now my poop was starting to spread upwards front and back in my bathingsuit.

Three girls entered the restroom and I could emediately tell that they where up to something. One girls asked the others if they had their "spare bikinis". Both replied with a "yes". They all entered the stall right next to me. According to their voices I thought they must have been about 15 to 17, or so.
My curiosity let me completely forget about my messy predicament. I went down on my knees to watch them under the wall.
All while still pooping in my one piece.
They stood in this stall facing eachother when one of the asked "So who's to start".
Without any warning the girl standing with her back towards me started pooping into her panties. I could clearly hear the typical crackling sound and she was grunting a little bit. Then the next one did exactly the same thing. While the third was filling her bikini panties, the first crouched down right in front of my eyes and began pushing onto the bulge in her panties with her bare hands. Even shoving it forward between her legs. In the end her mess was seeping through the fabric.
"Ew, what are you doing there, Megan?", her friends shouted out.
She told them to stay cool.
Then she stood up pulled the dirty panties down and crouched down again.

I still can't believe what happened next. She peed in her right hand and began to "wash" her filthy butt with it. Repeating the procedure until she was sure she was clean - wich she was definately not. They all put their panties on the groun in the middle of them and emptied their bladders on them.

Then they put on their spare bikinis and left.
As soon as they were out of sight I entered their stall and examined what they had done. The whole stall stunk like hell. I took up each pair of panties to have a closer look and a whif in them. Then somebody else entered the bathroom.

Now I became aware of my own state. My bathingsuit was filled up to the level of my navel front and back. And all around the sides, too. It was awfull. I knew I would be caught, if I'd attempt cleaning up right there. So I went to the lockers - luckily unseen - got my skirt and blouse on, took my shoes and stuff and left.

I got my bike and went for the walk home. I didn't dare to ride it because... you know. Half an hour later I finally arrived home.
I went straight to the bathroom and locked the door. I took of everything but my bathingsuit and stepped into the shower. Just as I wanted to turn on the water I felt a need to pee come on so I just let it flow. I felt the warmth spread on my skin again and how the pee was mushing up the poop. There was so much poop that not even a single drop of my pee leaked through.

Then I began peeling myself out of my messy suit. The lower half of the inside was smeared with poop, but worse was my body. It was caked in shit. About half an inch thick from my navel down till between my legs.
I began peeling off chunks of poop from my skin and tried pushing them down the drain with my feet, wich did not really work as it should.
It went better when I turned on the water. And then it still took one hour to get myself and my bathingsuit clean again.
