Running late and having to pee, Tina accidentally gets locked in an empty room with her faculty advisor while on a college visit. As they try to reach someone to let them out, she becomes more and more desperate and unable to hold her pee. She eventually loses all sense of modesty in front of her teacher as she keeps having accidents and wetting her panties bit by bit. She finally pulls down her panties and pees in a coffee mug but it's too small and she can't empty her bladder completely. Finally, to her humiliation, she can't hold it anymore and pees down her legs creating a giant puddle on the floor.
