Cosplay
The person wearing the survey corp suit, complete with her red scarf, is Mikasa Ackerman from Attack on Titan. Despite her struggle to hold it in, she gives in and urinates. She gives a little tinkle and then pisses again in her already-damp pants. As she urinates more, observe how the moisture travels down her pant legs. Mikasa displays her drenched pants once she has finished urinating in her tight jeans. Then she reveals her soaked underwear by pulling down her pants. She keeps flashing her drenched underwear front and rear till she eventually puts her jeans back up over her butt.
