Strong-willed elite bodyguard Sumire Mizukawa hates losing to men. During a presidential protection detail, she stops an assassination but is betrayed by an accomplice and captured. She is forced to give a titjob with the big breasts hidden beneath her suit, restrained and tortured with a vibrator by the superior she trusted until she wets herself, then raped in missionary and doggy style under a colleague's full weight. Three men gangbang her, force her to service two cocks at once, and creampie her as the overwhelming pleasure gradually breaks down her resistance.
