This is so hard for me.
One, as a submissive, I really get uncomfortable with that kind of power and control.
Secondly, if I were to plan a scene that is basically telling Sir what to do to me - I'm not sure if I would be into it. A large part of the appeal is that He is the one who chooses what he wants to do. What implements to use, how I will be positioned, etc.
Thirdly, if I were plan a scene that focuses on my serving Sir... it's very difficult. Sir does not respond positively at all to most forms of touch. If I'm not dancing around naked or actively sucking his cock, he is not interested. He likes massages, but that's about it. I'm also not allowed to touch his hair or feet, and he doesn't like being touched... really anywhere on his body. He actively moves my hands away from rubbing him. So the bag of toys we have are really not useful. I've thought about trying to perform submissive acts for his benefit, but part of the submission is succumbing to his will.
Fourthly, I think I would be... boring. Sir says that when it comes to me, I come up with brilliant ideas that he can use, without thinking first. But I don't know what I would do to him. Or for him that he would enjoy and not be over in 5 minutes.
Sir hasn't demanded that I plan a scene for us, but I wonder what would happen if he made me do it.
My stomach doesn't like the idea.
