Kanna Hazuki is an office lady working at a top-tier company, secretly harboring deep-seated masochistic desires. By suppressing her true nature, she has carried immense stress—until she arrives at a place where harsh yet pleasurable torment awaits. Her ordeal begins with hair suspension bondage: her hair tied tightly at the back and her hands bound behind with rough rope. A gag is then forced into her mouth, completely stripping her of bodily freedom as she's made to stand while her underwear is exposed and used to humiliate her. One after another, torments are inflicted—breast teasing, navel stimulation, face slapping, inspection of soiled underwear, choking, and crotch rope torture—each sensation gradually transforming her expression from resistance to blissful surrender. Next, she's laid down into a modified hogtie for intense tickling, then bound to a pillar for nose hook punishment, gagged again with adhesive tape, and finally subjected to relentless spanking. Her body and mind are pushed through this unending barrage of torment, guiding her toward an entirely new realm of submission.
