She felt the tingle and warmth of her collar halfway through her shopping trip. She filled her cart as efficiently as possible, and because she was in public she only felt teasing touches, though they were certainly distracting enough. They intensified slightly once she had left the store, carrying her bags the three blocks to her flat, and then they got even more intense as she raced to put away her groceries. By the time she was ready to leave, it was positively torturous. Throwing the last of the items into the fridge, she activated the collar and no sooner had she finished the word "Master,’ then she saw her kitchen fading away.
