Yes

"Oh god! Yes I have seen her naked when we shower after gym class, she is very beautiful." Jane was breathing harder now. I slapped her breasts again and asked her if she had thoughts about kissing her friend. "Oh John! Please, I have thought about it and we have kind of kidded around but we never did anything more."

I stepped back and looked at my sister the sweat pouring down her face as she swayed against the ropes. "I bet you want to do more than think about it don't you sis? You want to put your pretty face between her legs and lick her pussy." I pinched her nipples. "Come on honey you can tell me the truth."

"Please let me cum John, I need to cum so bad." Jane moaned and she tried to thrust her body at me. "I do want to lick her pussy, I don't know why but I do."

"All right sis you can cum now." I said as I sucked on her nipples while finger fucking her pussy. "I have to say it again sis but I love your breasts especially with the nipple rings attached." I teased them making her shake and shiver with pleasure. "So do you want me as much as you do your friend? What will you do?"

"I love you just as much if not more than Betty. Thank you for letting me cum. I am your slut John I can not deny you anything." Jane said as I finally let her have her orgasm. I asked her if that included her body. "My body is yours John."

I brought her back up into the living room and I sat her down on the sofa. "I want you to get your friend Betty, I want you to have sex with her but more important you will share her with me and I want to watch as the two of you have sex with one another."

I had Jane spread her legs as I prepared to enter her pussy. "You are a beautiful woman Jane, you will not have any real say about your slavery to me at least until you are totally immersed into your new life do you understand?"

"I understand John and I will do as you say."

"I want you to tell me the truth." I said. "Did you like being **** to suck my cock in public? Did you like having your tits exposed?"

"I did," Jane said breathing heavily as I started to fuck her harder. "I felt ashamed and excited at being **** to do the things I did."

"One rule you will have to follow from now on," I said. "You will not indulge in masturbation unless I tell you, if I tell you to undress you will do so quickly. I expect you to think for yourself, you are not a zombie. If you have a boyfriend drop him right away."

"His name is Phil we've only been out three times." Jane told me.

Well, you are mine now and you may return to your apartment on Monday but you will be here every day, you will not be allowed to wear clothing in this house unless it is something that I give you to wear. Do you agree to these things as I have presented them to you?"

"I agree to everything you said." Jane said sounding a bit resigned to her fate.

"I am glad to hear it sis," I said. "Now put your regular clothing on I will take you to dinner." As Jane exited the kitchen I said, "The reason you want to lick your friend's pussy is because you want to be a sex slut and that is what you really are, you are a slut who is about to embark on a journey of pleasure."
