Cumming in Kate

I figured that there was no sense in drugging her food, Kate was compliant and she ate her food with gusto. When I thought she was finished eating I had her stand. "You really are beautiful sis," I told her while I moved my hands over her body. "I have to tell you that I have often dreamed of a moment like this for a long time." I could feel her body quiver just a little. "What are you feeling Kate? Come on tell me what is on your mind."

My sister started to cry softly. "Kevin, I am sorry for being such a bitch towards you it wasn't right or fair." I cupped one of her breasts in my hand and gave it a gentle squeeze. "I don't think you should touch me the way you are touching me." She moaned as I twisted her nipple. I reminded her that I was now her master. "I know," she said slowly her tears continued to flow down her cheeks. She bent her head but I forced it back up so that she could look me in the eyes. "You have never seen me naked before and it makes me nervous."

"Get used to it sis," I said as I took her out of the cage. "You are my pet, my obedient pet." I said as I took her over to the table that I had set up. I told her to get on the table which she did. I tied her legs to the legs of the table and then her arms above her head. Her pussy was in the perfect position for penetration when the time came. "You are going to be my eye candy at any party and you will wear whatever I tell you to wear and I promise that the clothes will be revealing." All the time I was talking to her I was stroking her pussy.

"Kevin! What are you doing? Ah! God I am so horny, please make me cum Kevin and I promise that I will do anything you want."

"Sis, you are going to do what I want no matter what you think." I said as I blew some air across her damp pussy making Kate buck on the table. "That's what I like to see, my sister begging like a whore wanting to cum but can't."

She pleaded with me to let her cum instead of toying with her and I told her to say the magic words and I would let her have an orgasm. "Please Master, let me cum I can't wait any longer."

I made Kate cum and she let out one very long moan as her body tried to lift itself from the table. It was time to strike while the iron was hot. Kate watched as I approached her with my erection pointing right at her pussy. I rubbed my cock against her already wet vagina making her jump an gasp. I slowly pressed my cock into her and her eyes seemed to grow larger as I pushed my cock in even deeper. I started fucking her slowly at first waiting to see if she might try to move how ever awkward in unison with me. I was just thinking of fucking her harder when she seemed to move herself towards my thrusting cock.

"Fuck me sis," I said as I started to fuck her harder. "Your pussy is so fucking tight and you seem to be getting into it now."

I could see that Kate was trying to lift her pelvis at me although being tied to the table the way she was made it hard for her to do much. She cried out when I started to cum inside of her but I kept pumping my cock into her until I finished. "You were very good sis and for that you should be rewarded." I told her as I released her from her bonds.

"Thank you Kevin." She said as she sat up on the edge of the table. "Will I be allowed to go home now?"

"If you want to go home sis," I tell her. "You will wear this around your neck." I said handing her a collar with my initials on it. "This will let others know that you are not free to just do what you want. I am your master."

Kate put the collar on and when I told her to kneel down she did as I had told her. I moved in just to test her compliance. "Okay bitch I want you to suck me cock." I told her. "You may use your hands if you wish and you will have to swallow my cum."

Kate sucked my cock starting with the fondling of my scrotum and then slowly working her way up to the head of my cock. "Go on sis let me see how good a slut you are."

The next ten minutes the only sound in the garage was my sister making slurping noises as she sucked me off. I moaned with pleasure knowing that any moment I was going to cum in my sister's mouth. "That's it baby, take me deeper, show me you are truly mine." She did. As I came in her mouth she swallowed as fast as she could hardly coming up for air. "Good god! You were fantastic sis." I said as I lifted her from the floor. "You can be my cock sucker from now on."

"Thank you master." She said sheepishly. "What would you like me to do now?"

I told Kate how I had explained her not being home to our mom and all she could do was nod her head. "You can go back into the house now since you never really left." I said.

"What do you mean that I never really left?"

"This is the old garage that I turned into a special dungeon just for you." I said. "This is going to be your special place honey, I know how much you have enjoyed it here for I have it all on film."

"Oh fuck you didn't really do that did you?" Kate asked sounding shocked and worried. "What if someone should see it?"

"They would see my slut of a sister enjoying being taught that she is a servant to her lust." I said.

"I have been a bad girl Kevin and I will be a good girl with you from now on." Kate said. "And I guess if someone should see me being punished then I must have really been a bad girl."

"From now on sis you are my bad girl." I told her as we exited the garage. I didn't let her put her clothes back on, she had to walk to the house naked. "Damn it sis," I said as I opened the door to the house. "You are one hot looking cunt and I think after dinner you will sleep in my room tonight." Once inside the house I told her that tomorrow I would buy her some new clothes. "Your friends will envy you sis and they will never know that you are my cum slut."

"What about our mother? What if she finds out master?"

"Don't worry about mom, I will deal with her while you return to your normal life with one exception." I said.

"I understand," Kate said as she set about the kitchen to fix us something to drink. "I only have eyes for you and only you can fuck my pussy." She smiled as she sat down next to me. "How may I repay you for helping me see what I really am?"

"I will think of something I promise you."
