Training sis, plans for mom

I put a collar with a leash around Kate's beautiful neck and had her follow me from the garage; she didn't protest that she was naked she just followed me into the house and up to her bedroom. I sat her down on the bed. "You will no longer lock your door on me, you are from this point on my fuck slut."

"Yes Kevin I am your fuck slut. Would you like me to suck your cock Kevin?" She moved forward to take my semi-flaccid cock in her hands. I let her take my cock into her mouth while I stroked her hair. I liked the feel of her warm wet mouth on my cock, I told her not to make me cum too soon or I would have to punish her. She paused long enough to smile up at me before she continued to suck my cock. Of course no matter how careful she was I was going to cum in her mouth and when I did I felt sure that it had to have been one of the most powerful orgasms that I have had in a long time.

"Now go and take a shower sis, make sure that you trim your pubic hairs and then come to my room for inspection."

Kate came to my room an hour later showing me her almost bald pussy. I had her stand in front of me so that I could lick her pussy. Kate did not say no, she ran her hands through my hair, her breathing became heavy as she pressed herself against my mouth.

Kate tried not to moan too loud but she was holding my head to her pussy. "Make me cum again Kevin, make your slut cum!" I did make her cum and she moaned loud enough to wake the dead. I was sure that our mother would hear us but nothing happened. "Thank you Kevin, thank you my Master. Do you want me to share your bed tonight?" I told her that it would be best if we wait until tomorrow night. She nodded her head excepting what I said.

If our mother was surprised to see Kate home again she didn't show it and when she left the house I took Kate out to the old garage and into my dungeon. My sister undressed and stood before me. "Do you remember this joy riding machine?" I said. "The squirting dildo and how hard you came?" Kate nodded her head. "Go on bitch show your Master how much you enjoyed it, do it again."

I have to admit it my sister was very enthusiastic about using the machine and when I told her that she was being filmed she went wild cumming as the squirting dildo emptied into her pussy. Kate let me tie her to the bondage cross where I spanked her buttocks and then her tits but she really turned on when I patted her very damp pussy. "Ah, fuck Master I'm cumming!" Kate gasped as she strained against the restraints that held her to the bondage cross.

I fucked my sister while she was still held to the bondage cross and she told me how much she loved being my cum slut so when I finished and let her down from the bondage cross we walked back to the kitchen. We sat across from one another, she held my hand and asked me if she could see the video of her training. "Of course you can but first things first." I said. "You and I are going to do something very special." I said. Kate looked at me she was puzzled but interested. "It is really a simple plan really." I looked at my sister wondering how she would react. "I plan to fuck our mother, turn her into a cum slut just like you." Kate said nothing but there was a look in her eyes and I wondered if it was lust or something else.

Kate smiled. "Do you have a problem with that?" I said.

"No Master I am yours to command, I will do whatever you want as long as it pleases you. I will gladly help you with our mother, I think I would enjoy watching as you fuck her."

That was the moment that I knew without a doubt that Kate was no longer just my sister, she was my personnel pet, she will do whatever I want her to do. "Come to my room later." I said as I readied to leave the house. "We will make plans on how to deal with our mother."
