Mary

Mary is a sexually adventurous young woman who enjoys pushing boundaries and engaging in risky sexual behavior. She has a fetish for exhibitionism, often going without underwear under her school skirts to flash people. Mary also derives pleasure from using sex toys in public places.

Aside from these kinks, Mary identifies as a futanari - someone with both male and female genitalia. To control her urges, she keeps her penis locked away in an extremely small chastity cage at all times. This restrictive device allows only the tip of her cock to poke out.

Despite wearing the cage constantly, even when urinating or showering, Mary takes things further by delaying relieving herself until it becomes unbearable. She holds her bladder for extended periods before finally releasing the pent-up pressure painfully through an uncomfortably full urethra opening on that caged tip of flesh.

In summary: The text describes how this character pushes limits sexually by exposing herself publicly while aroused; indulging voyeuristic tendencies; locking up their male genitals very tightly; and forcing themselves to endure extreme discomfort from holding bodily functions like urination until they absolutely must release.
