Nina's feet, so delicate and graceful, are now Frank's playthings. He orders her to kneel, her bare soles pressing into the cold floor. He binds her ankles with shackles, leaving just enough room for her to balance. Frank runs his fingers along her arches, sending shivers up her spine. He brings out a foot whip, its leather tails caressing her skin before they snap down, leaving red stripes. Nina cries out, trying to pull away, but the shackles hold her firmly in place. Frank alternates between whipping and caressing, his voice a low, steady rumble, pushing Nina's limits. He forces her to service him with her bound feet, humiliating her further. Nina's feet are raw, her body shaking with exhaustion and endorphins, but she continues to serve, her mind lost in a haze of pain and pleasure, fully claimed by her Master.
