"My human toilet" is booming among the girls in this school. The well-metabolized girls often go to the bathroom because they often go out to the bathroom in a day, but since the school's bathroom does not have a cleaning function, a lot of tissue residue naturally sticks to the labia majora and labia minora. I'm sorry. The urethra also smells like urine, so I use it as a "human urinal" by letting a weak transfer student clean the urine and drinking it.
