So right now I'm kind of preparing for a rapid desperation challenge. I've been terrible drinking water lately so I'm trying for 600ml every half hour for the next 90 mins peeing whenever I feel like it, then at 3:30pm I'm having a cup of peppermint tea and keep sipping water and see how long it takes for me to lose control. I'm excited.
 

I have a poll for possibilities involving a bathroom line at school between classes, but there are a few other questions below, because I can only do three questions on the poll.
But before we go there, the general guideliens are:
1)  Can't be late and can't go to the bathroom during class, and class periods are usually 50 to 55 minutes in length.
2)  Peeing on the floor, trash can, sink, water bottle, chair, or desk are not allowed.  Each girl either pees in a toilet, or can’t make it and pees in her pants.
3)  Cutting in line is not allowed, even if those at the front of the line are not as desperate as the ones at the back of the line, because there is a line for a reason, plus no one is allowed to be late.
4)  Each girl will need a minimum of one minute of time in the stall before exiting.  It may take longer, and may take a lot longer is somebody needs to do #2.  But for the purposes of this topic, we’ll assume everyone only has to do #1.
 
 
Here are the questions:
1)   How long is each class period, and the passing time between classes?  Optional:  How many class periods and how long is lunch hour? (You could make it two minutes between classes, or you could make it 20 minutes between classes, but something in between would probably be more realistic.)
2)  How many stalls are in each girls bathroom, and which one are these girls heading towards?  Also, between which class periods (ie 1st/2nd, 6th/7th) will this scenario occur?  (You could make it 1 stalls, or you could make it 100 stalls, but something in between would probably be more realistic.)
3)  How strict are the teachers about being late, or using the bathroom during class?  (In other words, how many tardies before disciplinary action is taken, and how many restroom passes are allowed per class per semester?)
4)  What is the age and grade classification at this school in question (preferably somewhere between the 6th and 12th grades, where any combination of grades (ie 6th/7th, 7th/8th, 6th through 8th, 9th through 12th, or even 6th through 12th).
5)  How long is the line at the bathroom?  What are the names of the girls in the line (can add age or grade if you want), and how desperate is each particular girl to use the toilet?  (The length of the line could be interesting depending on how long the passing time and how many stalls are in the bathroom.  In other words, a line of 6 in an 8-stall bathroom with a 10-minute passing time is not the same as a line of 6 in a 3-stall bathroom with a 5-minute passing time).
Other variables you could add (or not add) to make it interesting could be:
1)  What if one or more of the toilets is stopped up before or during this bathroom break between classes?  This can significantly alter the flow of the line and might make a difference people arriving to class late, and will there be an extra time allowance for situations like that?
2)  Girls are (or are not) allowed to pee in the sink, trash can, floor, water bottle, desk, chair, or somewhere else.  You could allow any or all (or none) of those possibilities, or go with my scenario where each girls either pees in a toilet or can't make it and pees in her pants.
3)  Should "cutting in line" be allowed?   Probably not, but it's your call.
 
The idea is for you to make a scenario where at least one girl within the line has a full bladder that is about to burst and is very close to peeing her pants and certainly cannot wait another hour.  But yet there are too many girls ahead of her in line for her to be able to pee and still get to class on time comfortably.  Most likely, she'll be late, or just barely get there on time.  In other words, the scenario should at least make it "somewhat difficult, but maybe not necessarily impossible" that "X" minutes (whether the X be 3, 5, 7, 10, or whatever) is enough time to 1) make it to a restroom (takes time)  2) wait in line (takes time)  3)   pee (takes time) and 4) get to class on time (takes time).   That doesn't even count locker time or time to wash and dry hands either.   We can have some fun with these scearios.
 

POV: BRYCE
I’ve always been into pee, particularly desperation. The only person I’ve ever told is this girl I went on a few dates with named Kara.
Our first date was at the movies. We got popcorn and a large drink, which I didn’t even think we’d finish, but she got up and got a refill about halfway through. I barely had any, but Kara managed to finish the whole thing!
After the movie, she excused herself to the bathroom. On the way home, though, I noticed she was squirming and fidgeting, but I didn’t think much of it. As soon as we got to my house, she made a beeline for the bathroom. We started making out in my room. When it started to go somewhere, she said
”Hold on, I’ll be right back. I gotta pee.”
”Are you alright?”
”Yeah, why?”
”You’ve been going to the bathroom a lot.”
Her cheeks went a little red. “Well... Whenever I have sex, I make sure my bladder’s really full so I can pee afterwards. It helps to prevent pregnancy.”
”Really?” I asked. She nodded.
”Plus, I read it can make it more pleasurable. I drank too much though. I don’t want to have to pee too badly. It gets distracting, and kind of painful, so I go to the bathroom and let a little bit out.” I noticed she was bent over a bit.
”I mean, the fuller the better, right? Like, wouldn’t you want to pee as much as possible afterwards?”
She hesitated. “I guess, yeah,” she said, and sat back down. In hindsight, this was kind of sadistic on my part, but knowing her bladder was so overfull while I was fucking her drove me crazy. It was the best sex I’ve ever had. As soon as I came, she said “Okay, let me up.” She rushed to the toilet without shutting the door, sighing as her strong urine stream hissed out of her like a firehose.
Our next date was at a restauraunt. She went through the drinks like nothing, excusing herself to the bathroom numerous times.
POV: KARA
On the drive home, I had to pee so bad I couldn’t think about anything else. Bryce’s parents were going out, so we were going to his house again. I’m not supposed to be there after dark.
I wanted to pee a little bit as soon as we got there, but he was oddly enthusiastic about going straight to his bedroom. I decided I’d go as soon as we were undressed. A little while later, though, we heard something downstairs.
”Oh, shit,” he said, and hurriedly got all his clothes back on.
We hadn’t done anything yet, but I had already undressed down to my underwear. I was about to excuse myself to the restroom before we heard it. My bladder was swollen with hot piss and I couldn’t keep still. I was squirming a lot and occasionally squeezing myself.
”I need you to hide in the closet,” he told me. “My parents are super strict, they can’t see you here right now. I’m gonna go see what they’re doing home.”
He left before I could ask him what to do about my urgent need. I had to go so badly, but I hid in the closet anyway. Pretty soon, I was marching around and holding myself, rubbing in between my legs occasionally.
”Oh my god,” I groaned quietly. My bladder was full to bursting. I needed to pee so bad I wasn’t sure how much longer I could take it. Finally, I heard the car leave the driveway and he came back in the room. I came out, trembling and holding myself.
”Sorry it took so long,” he said, “my mom lost her purse. She’s freaking out. They’re going to check—“
”I’m sorry, I can’t hold it. I have to pee so bad.” I went towards the bathroom.
“Wait!” he said, “I think you should hold it.”
I shook my head. “I’m gonna explode.”
”No, just think about it. A full bladder supposed to make sex more pleasurable. If you’re really bursting, this’ll be, like, the best orgasm you’ve ever had.”
”I really don’t think-“
”If you change your mind at any point, you can just run to the bathroom and come back.”
”Fuck, I need to go, though!”
”It’s not like you can get hurt from holding your pee or anything.”
I was stepping around and squeezing my pussy intermittently  with both hands inside my underwear. “I guess,” I said, hoping I could hold it. When I got in the bed, I could feel the liquid sloshing around inside of me. He pulled my panties off and it got even harder to hold

As some of you may know, boys can generally get in and out of the bathrooms pretty quickly (sometimes as quickly as 20 or 30 seconds), but it's not as easy for girls because there might be a long line and you don't know what's going on.  They have to undo pants, and don't know if they have to do #1 or #2 or both.  At the very least, you can pretty much guarantee that it will take each girl a minimum of a minute to get into the stall, do their business, and exit the stall.  You may also know that some schools may not let people be late to school or a given class, or use the bathroom during class.  So, I thought I'd spell out the general rules before asking questions.
1)   There are five minutes between classes, and 50 minute class periods.
2) Can’t be late, and can’t use the restroom during class without some sort of disciplinary action, and asking the teacher to use the restroom before class will not work. 
3)  There are three toilets available in each girls bathroom (and there are either two or three total sets of restrooms in the building, not counting the nurse's restroom or the gym locker rooms).
     4)  There are at least 800 students in this school (and at least 400 of them are girls), possibly more. 
     5) There is a tall, skinny blonde girl (probably more than one) that  really needs to pee during one of the passing periods between classes.   
     6) This girl in question arrives at the restroom closest to her next class somewhere between the 1 and 2 minute mark (probably closer to the 2 minute mark) of break time (meaning there are about 3 or 4 minutes to go before the next class).
I have three questions on the poll, but here are some other interesting questions.
1)  What should this girl's name be?
2)  What is the age and grade of this girl (should be between 11 and 18 years of age, and between grades 6 and 12)?
3)  What is the grade range of this school (for example 6th grade only, 7th/8th grade only, 9th through 12th grade, or even 6th grade through 12th grade)?  I think the grade range should be at least 2 or 3 grades.
4)  What is she wearing on that particular day?
5)  On a scale of 1 to 10, how desperate is she to pee (or to put it another way, how full is her bladder)?
6)  How many girls are ahead of her in line, and how desperate do they look?  (Remember that there are only three toilets available in each girls bathroom.  Also remember that there are only five minutes between classes and that they can't be late and also can't use the bathroom during class).

Your middle school or high school school has a strict bathroom policy that says that you can't be late to a class more than once or twice per class per semester, and are only allowed maybe one or two bathroom passes per class per semester. So you are to use the facilities between classes, at lunch, before school, or after school. Depending on how many facilities your school has and how long passing time is, the bathroom lines may be too long to wait in line, do your business, and get to class on time, especially for the girls. What do you do? This scenario assumes that you are a girl and if you are late to your next class, you will get a 30 minute detention.  Also, you can’t go to the bathroom during class or you’ll get charged with a tardy and have to serve a 30 minute detention.  Asking the teacher to use the bathroom before class won’t work either, because you already used up any emergency bathroom passes you had during the semester (probably only had one or two anyway).  This scenario assumes that class periods are 50 minutes long, there are five minutes between classes, and three stalls in each girls bathroom.  There are two or three sets of bathrooms, but trying to navigate from one bathroom to the next if the line is too long probably won’t work because it will take time to get to the other bathroom, and the line may be just as long there.  Also assume that you can’t use the boys restroom because the line is too long in the girls restroom.  In addition, also assume that you can’t pee on the floor, in the sink, in the trash can, in a bottle, on the desk or table.  Also, if there is a line, cutting in line is not allowed unless everyone ahead of you in line from the place you are to the place you want to cut into says okay.  So basically, it comes down to waiting in line to pee (and probably being late), or possibly peeing your pants at some time within the next hour.   Although doing #2 is a possibility, most of the focus is on #1 (peeing).  Assume that it will take each girl at least a minute to do their business in each stall.
1)      What would you do if you had to pee in the middle of class and your teacher told you couldn't leave, and you said it was an emergency, and they told you it would be a 30 minute detention if you left class?
2)      Suppose your name if Tiffany and class periods are 50 minutes long, and you have 5 minutes between classes. You enter the girls bathroom about 2 minutes into the passing time, so you have 3 minutes left. Your next destination is probably about  30 seconds away. When you get into the bathroom, you see that there are 3 stalls all in use, and there are about 5 girls ahead of you in line. You are probably about 5 minutes away from peeing your pants (10 minutes at most). If you are late, or have to go to the bathroom during your next class, it's a minimum of a 30 minute detention. And asking the teacher first to use the restroom won't work. What would you do?  (Note:  Trying another bathroom probably won’t work because you’d have to come back down this way anyway to get to class, and the line is probably just long there).
3)      Suppose your name is Emily and you are the girl right in front of Tiffany in line for the bathroom.  Tiffany is practically in tears and asks you if she can cut in line.  You could probably wait another minute or so, but it could be the difference between being on time or being late for class.  You do kind of need to pee but could probably wait another hour if you have to.  However, you’ll probably be very desperate towards the end of next period.  What would you do?
a.       Let Tiffany cut in front of you in line, realizing that it might be the difference between her peeing her pants vs not, but also might be the difference between you getting to class on time vs late.
b.      Tell Tiffany that you can’t let her cut in line because you were there first and you have places to get to as well.
c.       Give up on waiting and go to class and hope for better luck next hour.  In that scenario, you’ll get to class on time, but might be very uncomfortable halfway through the next period.  Tiffany will have a slightly better chance of getting to class on time or not peeing her pants since you decided not to go.
