Office Lady Mika (pseudonym), a masochistic woman with a deep desire for rope play, tries masked play to indulge in her fantasies without revealing her face. The mask, much like a blindfold, seems to heighten her excitement and arousal. Immersing herself in a private, fantasy-driven world, she engages in unexpectedly erotic scenes. Under the mask, her true nature as a woman who craves intense BDSM training is brought out even more powerfully.
