Keeping Secrets

I was surprised to see my father waiting for us as I brought the boat up to the jetty where we moored the boat. "I heard about the storm and I got worried." He said as I stepped onto the dock followed by my mother and sister. "What were you doing out there?"

"Honey, I asked Keven to take us for a quick spin and the storm kind of crept up on us." Paula said kissing my father. "Kevin had everything under control the whole time. I wasn't worried and neither was Kate."

"Mom is right," Kate said as she kissed our father on the cheek. "We were snug as bugs in a rug."

"I guess you did learn something about boating after all." My father said with a warm smile. "All those classes I sent you to paid off."

My sister joined me in my car while Paula joined our father in his. Kate snuggled up to me her warm breath caressed my neck. "I really had a great time tonight." She told me. "I know that I have told you this before but I am really sorry that I was such a cunt to you," Kate chuckled and let her finger rest on my crotch. "This chain I wear makes me your sex slave doesn't it?"

"Yes it does," I replied. "In away my dream came true." Kate looked at me. " For the longest time I've wanted get you naked and to fuck you while making you mine."

"That was your dream was it? You dreamed of making me see that I was just a slut who would lust after your cock?" She said stroking my cock through my pants. "I have to confess something to you, I think that it is important." I asked her what she wanted to confess. "I need to be brought back into the dungeon my love."

"Why would you want to go back there?" I asked. It wasn't as though I hadn't taken her back into the dungeon since she became my sex toy.

"I know it might sound silly but I really enjoyed the things you did to me." She slowly unzipped my pants. "The flail, humiliation, the fuck machines, and the bondage cross. You are my master and I must please you." She was stroking my cock now. "Let our mother watch as you spank and fuck me I don't care just as long as I can make you happy."

I was glad that Kate and Paula had removed the collar that had SLAVE on it after all I doubted that my father would have found them comforting and they would raise a lot of questions. My sister must have guessed what I was thinking. "Mom thought it best that we don't wear our slave collars when father is around." She said as she unzipped my pants and pulled my cock out so that she could touch it. "But this chain that you put around my neck has the initial S for slave and slut which is what I am Kevin. I am your salve."

I don't know how I managed to drive the car for Kate started sucking my cock while I was driving. "For fuck sake sis you might cause me to drive off the road!" I gasped.

"I can't help myself, I need to taste your cum my dear brother. I want to prove that I am your willing slut."

To be honest I have no idea how I managed not to wreck the car as I blew my load into Kate's warm mouth. I asked her if she was bothered by the fact that we were brother and sister. I could not really see the look in her eyes but I felt that she sounded dare I think it, happy? "I suppose that I should be more than bothered that my brother is fucking me," She said and I could see her smile in the glare of the passing headlights of cars going in the other direction. "But I am not bothered at all." She stopped talking but I did notice her hand reaching for her throat where the chain hung around her neck. "I don't know how to describe how I am feeling, I only know that I need to be your slave, I think tonight when we went to the restaurant and you had me wear that collar I knew without a doubt that you were my master/brother and I was meant to be your cum slut."

I pulled the car into the driveway next to my father's car and as we exited the car i told my sister that our mother felt the same way. "I know she does," Kate said as she took my hand in hers. "She told me how she felt while buying the chains that we both wear."

Later that night I brought Kate out to the dungeon where she quickly undressed and got onto her hands and knees and crawled to where I was standing. "I am ready for my punishment now Master."

"This isn't punishment honey, it is a reward for you." I told her as I had her climb onto the table and I strapped her down with her arms and legs spread wide. "This is a reward for being such a good girl today." She smiled up at me, the light gleaming on the collar that had the words SLAVE on it. "Tonight I have something special for you."

I pointed to a battery and to four clamps. "I think you will really enjoy this." I said as I attached the clamps to her nipples and to her labia. "I will send just enough juice through these clamps to make you cum and then you will beg me to fuck your pussy."

I inserted the ball gag into her mouth and turned on the power. I kept my promise to use only enough juice to make her buck and moan. From where I stood I could see her juices gleaming as they slowly slid down her pussy. "How does that feel bitch? Are you ready for my cock yet?"

Kate moaned as her body heaved and bucked against the restraints that held her to the table. I knew she was having an orgasm. "Are you ready for me?" I asked again and she nodded her head that she ready.

Before you could count to ten I had the clamps and the ball gag off and I mounted her. "Yes Kevin! Fuck me hard my master, your slave loves you and wants your cum filling her pussy!"

After I finished cumming inside of her I let her up from the table. "That was really weird and fantastic Kevin." Kate said as she kissed me. "I felt as though my whole body was on fire and how much I wanted you inside of me." As we started from the dungeon she said, "I want you to know that I am in love with you and brother or not I want you to get me pregnant, this will be my way of showing you and the world just how much I am yours."
