Showing Paula the truth.

After Kate finished fucking our mother with the strap on I returned Paula to the cage. I tossed a new collar onto the cot. "Put this one on in place of the other one." I said. The new collar had the words "Slut" engraved on the platting. "This is the one you should wear when you meet you Master later on."

Kate and I exited the dungeon and headed for the kitchen. "Sit on the table bitch and spread your legs for me." I told my sister. "You looked like you were really turned on when you fucked our mom." I said as I slid my cock into Kate's pussy. "You are as big a whore as our mother aren't you?" Kate spread her legs. "So my darling sister what are you?" I started pumping my cock in and out of my sister's hot pussy.

"I am your cum slut Kevin, my pussy is yours, my body is yours." Kate said as she held onto me. "You are my Master my love, fill my pussy with your cum please."

Time flies when you are having fun so when I finished fucking my sister I looked at the clock. "Time to feed mother." I said as I put on a pair of shorts. "I also think it is time to reveal myself and you to her."

Kate followed me out of the house, she was still naked just as she had been naked all day. I told her that there would be no need for masks or changed voices. Our mother looked up as Kate and I entered the dungeon and she gasped. "Kate, why are you naked and Kevin what are you doing here? You shouldn't see me like this."

I know that my mother was surprised when I took Kate in my arms and kissed her full on the mouth and my hand between her legs. "Kate you don't mind do you?" I said.

"Not at all Master, my pussy needs you even as we speak." She said.

"Bring mother out of the cage darling, have her get on her knees." I said.

"Right away my love." Kate said as she entered the cage and brought our mother out into the dungeon proper. "May I lick her pussy again Master?"

I saw the look of surprise on Paula's face. "That's right slut, Kate is the one who not only licked your pussy but she also used the strap on to fuck you."

I lowered my shorts and exposed my cock. "Take a good look bitch, you are going to see a lot of my cock from now on." I said as I approached my kneeling mother. "I am your Master do you understand?"

I have to admit that it was strange to see my mother cry but in many ways she brought it on herself. "Kate bring mother over to the table and strap her down." I said.

Kate smiled took our mother by the collar and walked her to the table where she pushed her onto her back with her legs hanging over the edge. She tied Paula's arms above her head and her legs to the two legs at the bottom of the table. I walked over and looked down at my naked mother. "You really are very beautiful mom but you have always treated me like dirt." I stroked her hair and then her breasts tugging lightly on the nipple clamp chain making her groan. "You are my slut now mother, your pussy belongs to me." I said giving it a gentle pat which made her buck against the straps that held her to the table. "My oh my mother your pussy is already wet. Does that mean you want to be fucked?"

I continued to work her pussy until till she finally said, "Please Kevin, I'm really sorry for the way I treated you, I promise that I will behave myself from now on." She was writhing against the straps. "I will do whatever you want honey but please you mustn't put your cock into me."

"That isn't good enough mom, you will submit to me in all things after all that is what the training has been all about."

I put my face against her wet pussy and I began to lick it. "Ah! Kevin please! I can't do this!!!"

"Of course you can, deep down inside of you you want this to happen." I said. "You want me to fuck you as punishment for being such a bitch."

I made my mother cum, her eyes glazed over as I finally approached her vagina. "I've waited a long time for this Paula, tell me you want me to fuck you."

"Yes, yes I want you to fuck me, I am deserving of this punishment." She said.

I started slow pausing every few pushes just to see how she was doing. I watched her chest move enticingly with each deep breath she took, her sighs seemed to grow louder with each stroke of my cock inside of her pussy. I wanted to make her cum while my cock was inside of her pussy. "Come on bitch, cum for your Master, I can feel your pussy grasping at my cock not want to let it go, you want me inside of you."

"Oh god Kevin! I...I'm going to cum please I promise to behave myself just let me cum!"

"Of course you will cum Paula, but you have to tell me that you want me to cum inside your pussy and that you are my pet, willing to do whatever I want you to do." I said.

"I am your willing pet, I will do anything you want for you are my Master." Paula said.

So my mother was now just like her daughter and my sister a subservient sex slave.

I let Kate lick our mother's pussy after I came inside of her. When I released Paula from her position on the table I told her that she was to give me a kiss and then she had to kiss Kate. My mother really is a very good kisser and she seemed to enjoy kissing Kate just as much as she enjoyed kissing me.

I had the girls walk back to the house in the nude and once inside I told them that tonight they would sleep in my bed.
