A bound male slave, his thick cock straining against a cock ring, endures a merciless tease from his Mistress. She worships his big, bound cock with her mouth, relentlessly bringing him to the edge of orgasm, only to deny him release. His begging grows louder, his body writhing in restraints, as she expertly controls his pleasure, her teasing licks and deep throating pushing him closer and closer to the edge of insanity.
