A Chinese gay slave's ass undergoes a rigorous dilatation training, his body quivering with each intense thrust of the master's fist. The master starts with a thick dildo, fucking the slave's ass until it's gaping wide. The slave's whimpers of pleasure and pain mingle as the master replaces the dildo with his fist, pushing deeper and deeper until his entire hand is inside the slave's stretched asshole. The slave's body is covered in sweat, his asshole dripping with lubricant as the master trains him to take more and more. The master's dominant voice commands the slave to relax, to open up, as he continues to stretch the slave's asshole wider than ever before.
