Iris - Unprepared Student

Iris is studying at an agricultural college and today is the day of an exam that is very important for her. Unfortunately the professor is really mean and Iris can hear him shouting at a fellow student who is taking the same exam today. Iris is pushing her crotch - she is really nervous. The professor is experienced and immediately notices Iris is totally unprepared when the exam starts. She's not a good student and the professor starts shouting at her too. The combination of stress and pressure in her bladder is devastating and Iris pees herself after a while. She fails the exam (despite wearing a really short skirt because the professor is said to like such young looking girls) and leaves the room - the only thing she left behind is a puddle of warm urine...
