Level up on Kate

It was late in the afternoon when I returned to the garage and once more put on my mask. I came into view of the cell where my sister sat crying softly. "How is my little concubine doing? You should be well rested by now."

Kate looks up at me. "I am not your concubine, please you have to let me go."

"That is true Kate you are not my concubine but you will soon have a master and you will be eager to please him." I said as I entered the cell. "Stand up bitch and turn around." My sister stood and turned to face the back of the cell. I handcuffed her hands behind her back. "Come with me cunt, I think you need more time on the wooden horse."

"No! No, please not that again I beg you." Kate begged me. I tied her up just as I did earlier and I placed her on the horse and once again her weight pressed down on the frame digging into her pussy, her moans were muffed because of the ball gag. She was already drooling and I was pleased to see that her pussy was already gleaming with her juices.

"I'll leave you now, think about what I said Kate you were made to be a concubine. I'll be back shortly."

I left her on the horse for about ten minutes when I returned I lifted her down from the horse and removed the ball gag. "What do you have to say now bitch?"

"I will do as you tell me." Kate said. I knelt in front of her and slid my finger into her pussy making her moan. "Please I can't take much more I'm so sensitive right now."

I made her cum and then I untied her legs and got her on her knees. "All right bitch suck my cock." I told her as I unzipped my pants. "Make me cum in your mouth."

Kate was not eager to suck my cock but she did as I asked. I told her how good her mouth felt on my cock and that she should take me deeper into her mouth. "Don't be shy, I'm sure that you've sucked your boyfriend's cock so you will do it for me."

I was close now so I held onto my sister's head and forced her to suck faster and deeper. "That's it slut, make me cum." I filled her mouth and she swallowed as fast as she could gagging just a little as she tried to keep up with my spurting cock. When I was finished I wiped my cock on her lips. "You really know how to suck cock honey you will make a good toy for your master." Now I will take you back to your cell, you will clean yourself up and if you are good I will have food for you."

I closed the cell door, locked it and walked out of sight so that I could remove my mask. Two more days should do it I thought my sister looked ripe for the picking now for I would make her my concubine and she would be happy about it.
