Gaste85, dressed in a tight, white miniskirt and blouse, is caught off guard by a sudden, strong urge to pee. She's in the middle of a lecture, her seat growing warmer by the second. With a mischievous glint in her eye, she decides to let nature take its course, feeling the relief as her bladder empties. The liquid seeps through her skirt, creating a dark stain that grows with each passing moment. She shifts in her seat, enjoying the sensation, her arousal evident as she continues to sit in her self-made puddle.
