The master, a seasoned sadist, admires his slave's body, ready to push his limits. He orders the slave to his knees, presenting his ass. The master runs a finger along the slave's crack, feeling the tightness that awaits. He lubes up his leather-gloved hand and slowly inserts a finger, then two, preparing the slave for what's to come. The master replaces his fingers with a thick, black dildo, pounding the slave's ass with increasing force. The slave, lost in his subspace, begs for more, his body trembling with need. The master, satisfied with his slave's progress, rewards him with a intense, brutal fucking, leaving both master and slave breathless and spent.
