The message instructed you to find the four pairs of handcuffs on the bed - those were easy enough. Then you were supposed to cuff yourself spread-eagle to the bed. With your mouth gagged, and your eyes blindfolded, and wait for Mistress Fire to arrive. When she arrived, what would happen?
You locked two of the handcuffs to the lower bedposts. You gave a quick scan of the room, but didn't see any keys. Mistress Fire probably had them with her. You were VERY nervous. If you followed through with these instructions, you would be completely helpless. You were definitely excited by this fantasy, but the reality of it was a totally different thing. You were at odds with yourself. But, you remembered, MF had pictures and videos of you. She knew all the same people you knew. And she was capable of sharing those pictures and videos with those people - something you absolutely did NOT want. So, you had to comply. You already had the gag strapped over your mouth. The cuffs were now attached to all four posts of the bed. And you were ready to lock your first foot into one of these cuffs.
