In a dimly lit dungeon, a bound woman awaits her mistress. The dominatrix appears, her silhouette menacing against the soft glow. She commands the slave to her feet, pushing her against a pillar. The mistress' gloved hands grip the slave's chin, tilting her head back as she shoves her cock down the slave's throat. The slave gags, tears streaming, but the mistress shows no mercy. She then attaches a strap-on, mounts the slave, and drills her pussy, making her scream and beg for release, only to be denied, as the mistress continues her relentless pounding.
