Afterwards, they subject him to intense sexual torment and begin interrogating him to extract vital information about his organization. Despite having his body violated and his dignity as a man stripped away, Zan'ei refuses to yield under questioning. Amidst overwhelming waves of pleasure and pain, what fate awaits him?
