~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I walked around Janice and stepped between my two sluts, laying a hand on each of their heads, and they instantly looked up at me each wrapping their arms around one of my legs. "They won't answer you, Slut. They belong to me now."
Janice looked at me, and I could see the hate in her eyes. "You think you have the control to take my toys from me little Greggy?" She snapped her finger and looked at mom. "Carol, come here right now, or Mistress will have to punish you."
Mom didn't even look up at her. I took my hands off both Charlotte and Mom's heads and they both looked at me. I smiled at my sister. "Go get ready for bed, Charlotte. I'll be up when I'm done talking to Janice slut."
"Yes Master."
Janice screamed. "Don't you move bitch! I own this family, not that little wimp!"
I looked at Janice and she tried to stare me down. I caught her eyes and then pushed as I said. "Janice, you will be silent and not move unless I ask you a question or tell you that you can."
I could see that she was going to defy me to prove I wasn't in control. She opened her mouth and realized she couldn't speak. Then she started to shake as she tried to move and couldn't. I laughed at her. "Look at me Janice, don't look away until I tell you that you can. You think you're dominant, but you aren't. If you were, you'd be able to resist what I'm telling you to do, but you can't. In fact, you're the weak one. You're the submissive one. You're starting to realize that now. You've only been acting like the Dominant because you didn't know what a true master was. However, now you will soon. I'm the actual Master here. I'm your true master, and I'm going to prove it to you tonight. Once I do, you will fall at my feet and beg me to make you my pet, and if I think you're worthy I might accept you as my lowest slut or I might reject you and let you leave feeling lost and hopeless. Now Strip! I want you naked like all good sluts should be."
Janice's eyes widened with disbelief as against her wishes her body obeyed me, and she started removing her clothes. She looked back at me now with fear and confusion instead of anger. For the first time I saw in her mind that she was beginning to think I might actually have been right, and she wasn't the dominate Mistress she thought she was. Her complete surrender to me was going to be fun.
I walked over to Janice and patted her on the head. "That's a good girl Janice, you're going to be a very good submissive slut." Then I stared into her eyes again and pushed. "From now on, when I say you are a good girl you will instantly become aroused and need me to stick my cock in you. You hate that it arouses you, and you will try to fight it; but the harder you fight it the more you need my cock in one of your three slut holes."
The fear in her mind actually excited me. Finally, I wasn't the one everyone could whip on. Now I was the one cracking the whip. "I'm going to release your body in a moment Janice, but you will not try to leave this room. You also will not attempt to harm me or anyone else in this house. I'll let you speak again too, but you will not yell or scream, you will speak in a calm and normal tone of voice. You will not try to contact anyone outside this room. You can now move and talk."
Just like I expected Janice reached down to get her clothes. I pushed at her again. "You will not redress or cover yourself in any way, slut. Take a seat on the couch."
Janice stopped picking up her clothes and walked over and sat on the couch. "How are you doing this?"
I smiled at her "That's a good girl, Janice." I watched as she fought against the need to have me inside her. I decided to answer her question. "I told you Janice, I control you. I'm a true Master and all the submissive sluts must obey me."
She was panting with need and the smell of her desire was permeating the air. "Oh God." She finally broke and reached for my throbbing cock as she hissed. "Fuck me, you bastard!"
I stepped back out of her reach. "You are not in control here, slut. If you need something from me, you will beg me for what you need. You don't command."
She pulled her hand back and gritted her teeth trying not to do as I said. I laughed at her. "You can't win, slut. I'm going to ask you some questions and you will not be able to do anything but answer them fully and honestly. You can't lie or even try to misdirect me."
Janice groaned and started rubbing on her clit trying to get relief. "No touching yourself slut."
Her hand moved away from her hot button and she finally broke. Oh God! Greg, please fuck me. I need it! I can't stand it anymore shove your cock in me. Please shove it in my mouth, my pussy, my ass I don't care where, just fuck me!"
"Why should I?"
"What? What do you mean why should you?"
Why should I grace you with my cock? You don't belong to me. Remember you're the big bad Mistress. How many submissives, besides my mom and dad, do you have anyway?"
"Five, I have five other submissives."
"Five, so seven with mom and dad. One for every day of the week. Who are they?"
'My doorman Jim, my P.A. Terri and Barbie and Candice both of which are students at the community college. Please Greg, I can't hardly think. Please stick you cock in one of my holes."
"Not until you admit that you're a submissive slut not a Domme."
"But I am a Domme. Maybe I'm a switch, like Silas."
"You aren't a switch. I'll prove it to you. Which of your female sluts is the prettiest?"
