In a dimly lit dungeon, Mistress Kinkycore commands her submissive to lie back on the medical table. She begins by clipping clamps onto her eager labia, causing the sub to squirm in anticipation. The Mistress then inserts a speculum, revealing the glistening inner walls of her pussy. She meticulously examines her, running a gloved finger along the sensitive flesh before inserting a catheter, filling her with a sense of fullness. The Mistress then brings out a vibrator, teasing her clit as she slowly pumps the catheter, driving her submissive to the brink of orgasm.
