Mistress V, the stern and dominant trainer, oversees a rigorous BDSM session focusing on chastity and sissification. Sissy Slaves B and C, locked in steel chastity devices, endure her cruel training. They're paraded in lingerie, made to pleasure each other while denied release, and humiliated with verbal and physical degradation. The session culminates in an intense orgasm denial, leaving the sissies begging for Mistress V's mercy. -
