In "The Italien Lesson Vol. 4," Mistress Regina, clad in black latex, oversees her slave's degrading transformation. She humiliates him, forcing him into a public cage at a crowded event, his cock-cage visible through his tight shorts. She spanks him, leaving handprints on his ass, and orders him to clean her boots in front of the leering crowd. The slave, humiliated and aroused, complies, his body trembling with shame and desire.
