Kate's Dream

Tired from the long day, Kate goes to xxx. Soon she begins to dream. But what kind of strange dream is this? She is bound with a xxx, handcuffs, gag and anklets. Is there a hidden wish coming from her subconscious? It certainly doesn't seem like a nightmare. When the alarm clock rings and she wakes up, she notices the xxx. But it was only a dream, where does the xxx come from now???
Kate speaks English.
