Sayaka has been squirming all throughout class, but try as she might,
she just can't ease up her need to pee. She is so desperate now that she
really does not know if she is going to be able to hold it until class
is out or not, but she is trying her best. Her bladder throbs, and with
her legs tightly crossed and her hands jammed down into her lap, there
is little more she can do to help herself hold it.

By now, Pop has noticed, and is silently rooting for her friend to be
able to hold her pee until class is out. Her need is so obvious that she
must be near her absolute limit, but the fact of the matter is that
there is only a few minutes left of class.

The minutes seem like they are ticking by ever slower and slower, but
Pop is just sitting there, biting her lip and waiting to see what is
going to happen. She is nervous about her friend having to pee herself
in class, but she also is curious as to how bad it will be, and is even
kind of aroused at the prospect of her friend getting wet in public,
though these are feelings she doesn't understand.

But then, the bell rings, and Sayaka is still dry. Pop breathes a sigh
of relief, and starts to pack her things away into her backpack. Just
when she thinks her friend has managed to escape a terrible accident,
she hears Sayaka cry out in pain and desperation, and then a hissing
noise fills the room. Pop looks back at her, and sees that Sayaka is
peeing full force into her chair, a large puddle spreading beneath her.

"Oh, Sayaka!" Pop cries, rushing to her friend's side.
