In this explicit femdom scene, a power-hungry woman takes control of her submissive's urinary tract, inserting and stretching their urethral opening with an array of medical instruments. She begins with a gentle speculum, but quickly progresses to larger, more invasive tools, like the infamous Hegar sound. The submissive's moans fill the room as their pussy hole is widened, their clit engorged with desire, and their body convulses in ecstasy as they near their climactic release.
