Class was a tricky ordeal. It was bad enough that Jenny had to split her attention between the lectures and aiming her stream into the bucket, but there was the added difficulty that her bucket would get filled pretty quickly. Most of the classes, it would be close to overflowing once class let out, leaving Jenny with just barely enough time to take it down to the bathroom - carefully, or she'd spill it and get in trouble - and empty it before going to her next class and repeating the cycle over.
As the day went on, Jenny noticed that she was feeling thirstier than usual. Which she tried to ignore the urges to drink up, it was proven futile when she noticed, near the bathroom, a crotch-level drinking fountain, seemingly specifically for her.

The teacher rolled his eyes. "Well, then you shouldn't have drank so much, or maybe carried a bigger bucket... in the meantime, you may go to the bathroom, but I expect to see you after class to make up for the lost time... and clean up your puddles."
Yeah, while the teacher has been talking, Jenny has still been peeing from her face-pussy, the pee overflowing onto the floor where she stood. Apologizing, Jen started rushing to the bathroom, pee trailing from the bucket as she went along. She started muttering under her breath about what she was going to inflict on Kyle, when...
