A petite brunette, dressed in form-fitting gym leggings, is at the end of her tether. She's been holding her pee for what feels like an eternity, her bladder aching with the effort. She tries to focus on her surroundings, but the pressure is insurmountable. With a whimper, she lets go, her piss soaking through her leggings, creating a massive wet spot. She hastily strips off her soaked leggings, revealing her glistening pussy, and begins to touch herself, seeking release from her taboo desire.
