Every weekend, Kanna Kitayama becomes obedient to men without fail. Going far beyond her role as a secretary, she faithfully follows the man's commands, her alluring body bound and trained under strict discipline. Her big tits restrained by tightly knotted shibari ropes, she is relentlessly pleasured from within, her reason crumbling away as she drowns in ecstasy. Polite yet desperate, she pleads over and over, crying out, "Please... I beg you... Fill me inside with your thick, smelly cum..." Her passionate, animalistic surrender strikes deep into the heart.
