I actually have an idea. Maybe this girl named Fran has a very weak and tiny bladder, and she can barely go one hour after drinking without feeling an urge. So one day, Fran is wearing tight skinny jeans and she is taking a walk with her twin sister in the woods. Fran, unfortunately, takes lots of large gulps of water from her water bottle. Less than an hour later, she starts feeling the familiar ache and tingle in her bladder, alerting her that she needs to find a place to "go", and fast. For a while she tries to hold it inside by doing a little potty dance as they walk, and holding one of her hands under her belly button desperately. However, during a break in walking, her sister Julie sees Fran crossing her legs and squirming around. Julia has an idea. She walks over to Fran and says, "Boy, am I thirsty." She takes out her water bottle and sloshes it around, and then gulps her water loudly. Fran winces and holds below her belly button tighter, but she keeps quiet. She couldn't hold it much longer. Julie smiles and says, "I like walking in the woods, because you can see lots of rivers. Yep, those rivers have lots of water, don't they? It bubbles and gushes and-" Fran gives a small 'eep' and holds in between her thighs very tight, her legs are trembling. She had never felt this full of water her entire life, and Julie was trying to make her burst! "Julie please stop, my bladder can't take it. I'm sorry I tried to hold it inside me, I-i think I'm going to-" she never finished because Julie said "and I absolutely LOVE waterfalls, the water is so wet!" Then Fran wets herself, and Julie laughs. You don't have to give me credit for this, you can say it was anonymous.
