Mistress Kalyss Mercury, a seasoned dominatrix, unleashes her inner sadist in this intense femdom scene. Her slave, P, is bound and gagged, ready for his chastity pegging session. Kalyss teases him with a big dildo, slapping his face and balls before securing the strap-on. She takes her time, exploring P's vulnerable ass with her fingers, lubing him up for the giant dildo. With a wicked grin, she pushes the massive head against his tight hole, slowly inching it deeper until P moans in both pleasure and pain.
