The next morning over coffee, Charley asks "Did you enjoy our little play session yesterday?"
"Very much! I haven't been that turned on for quite a while."
"What did you enjoy?"
"The feeling of your command over me. How slutty I felt. How I didn't have any control over what was happening. It was incredibly erotic."
"So you would like to continue exploring? In that case, we need to discuss when, what limits you have, and a safe word and a gesture."
"Safe word? Gesture?"
"Yes, something you can say so I will stop what I am doing with you. It is for your own protection because I won't listen if you tell me No or Stop. There will be things I will demand of you or will do to you that will stretch your limits but will be things you will enjoy in the long run. A gesture because sometimes you won't be able to talk and will need a way to tell me to slow down"
A shiver went through her as she contemplated what Charley just said. Stretch her limits? Won't listen to her when she says "No" or "Stop?" "Won't be able to talk?" What was he planning on doing to her? But at the same time, she could feel her pussy getting wet with just the thought of what those words implied. Before she was even aware she had made a decision, she realized words were coming out of her mouth.
"How about "Pinocchio"? That's certainly not a word that would come up in a normal conversation."
"Good choice. Now how about a gesture?"
"No, not that one" as Sara flipped him the bird. "Can you do that Vulcan greeting still?"
"Like this?" as she proceeded to hold her right hand up in the greeting that became famous with Star Trek.
"Good, now that we have that work out, let's discuss what you want to try."
"I haven't really given it much thought."
"Well, what fantasies have you had? What excites you when you read erotica?
"Oh god. Being tied up, spanked. Oh I don't know! I just don't have that much experience in this stuff."
"That's ok. I'll take it slow for now. But you will have to submit to my discipline while I am training you."
"Discipline? What do you mean?"
"Well, you said spanking. That is one of the things I will do when you displease me. Other things may be more psychological, perhaps humiliating. Later, as I get to know your tolerance for pain, I will use a flogger and things like that."
"Flogger? I don't know."
"Don't worry, I won't push you too far, too fast. But understand that I will push your limits and before too long you will come to understand how pain can increase your sexual pleasure."
Once again, a shiver went through her body. What was she getting into? But she trusted Charley, probably even loved him. Besides, her pussy was so wet that she was sitting in a puddle. "Ok, I am sure you know what's best."
"Good girl."
Usually someone calling her a girl or praising her that way would have made her mad. But this time it sent a wave of pleasure through her, she had pleased him.
"Sara, I don't think either of us wants this to be 24/7, at least for now. So we need to define when I am your Master and you are my sub, differentiate those times from when we are our vanilla selves. One thing I will expect to wear when you are my sub is a collar, just like you wore yesterday. So that will be the sign that you are my property and not my girlfriend."
Sara was a little taken a back by hearing that she would be his property. That was not something she had even conceived of. But the more she thought about it, the more exciting and right it sounded.
"Also, Sara, it would be best for you to have another name when you are my sub."
At this point, Sara realized how much Charley had thought this whole thing out. It made her feel better knowing he was experienced and that he cared so much for her. "How about Genie? You know, like in that old TV show. I could even wear a little harem outfit."
"Genie, I like that. But I doubt you will be wearing clothes much as my sub. I like my subs naked and kneeling on the floor before me. But now that I think of it, I might enjoy having you dressed like that, perhaps when I show you off to some of my friends."
"Show me off!!? What do you mean? This is supposed to be our secret."
"First, never question me when it comes to what I will do with you! When you are my sub, I am responsible for you and would never do anything that would jeopardize your normal life. Do you understand!?"
Sara looked at him mutely; she wasn't sure how to react to this new commanding Charley.
"Answer me!"
"Yes, I understand Charley."
"Sir"
"What?"
"You will always me as Sir or Master when we are in our roles. Now answer me again!"
Sara was shocked but answered anyway. "Yes, Sir. I understand."
Then Charley said "That's a good girl" and patted her on the top of her head.
Sara's emotions were a mix of humiliation, anger, contentment, and arousal. She didn't know what to think. So she didn't say anything.
