In a seductive yet eerie establishment, waitress Reina Kawahara, clad in a sheer costume, undergoes forced lesbian training by Yui-baba. Her hands are tightly bound, a collar fastened around her neck, and her vision completely obscured by a blindfold. Amid relentless punishment, Reina pleads, "I'm sorry, but I'm getting aroused..."—her expression a mix of pain and ecstatic pleasure. The scene captures a shocking clash between brutal discipline and burning desire.
