In a clinical setting, Mistress Priest, a dominant nurse, ensures her trans slave remains obedient in a straitjacket. Gloved hands glide over the slave's body, pinching nipples, before she lubes up a steel sound. With a mischievous smile, she inserts it into the slave's needy, throbbing pussy, twisting and pushing deeper. The slave's moans fill the room as Mistress Priest expertly plays with the sound, teasing her slave's limits, pushing her to the edge of pleasure and pain in this intense medical fetish roleplay.
