Unfulfilled Sister

My older sister Kay had been married for a couple of years now. She wasn't getting along with her hubby Rick very well these days. Kay would stop by my apartment to complain about the state of her marriage.

"Why do you stay with that guy?" I would ask her.

She didn't have to answer me, I knew the reason. Kay was on the heavy side. She had wide hips and big breasts. She suspected that Ray was cheating on her. She was afraid no one else would want her so she stayed in her unhappy marriage.

We were sitting on my sofa and I was looking over her body. My sister was no beauty but I was damn horny right then.

I moved close to Kay and I placed my hand on her thigh.

"What the hell are you doing Ben?" She asked me.

"You're horny and I'm horny, you shouldn't be complaining," I said to her.

Kay tried to act like she didn't like what I was doing but she couldn't fool me. I used my other hand to move to her chest and I squeezed one of her big tits.

"Fuck, are you trying to get me worked up?"

I didn't have to answer her. I could see my sister wiggling around as I touched her thigh and tit. I wasn't going to let this opportunity pass. I stood up and began to shed my clothes. Kay's eyes got wide when I finally stood before her with my cock dangling in front of her face.

"You know you want it," I told her.

Kay looked at my face and then my dick. After a long pause she moved closer and took my cock in her hand. She slowly began to stroke my prick and then she brought the head of my shaft to her mouth. Kay inhaled my cock and took me down her throat. This was just what I needed. Kay made these slurping noises as she went up and down my prick. She eventually pulled away.

"You're so much bigger than Rick," she said to me.

That was all I needed to hear. I pulled her up from the sofa and I began to undress my sister. It was just as I thought. Her tits were sloppy big and hung down on her chest. Kay also had a belly on her. It didn't matter to me. I needed fucked. I pushed my sister back to the sofa and made her get onto her back.

"We really shouldn't do this," Kay said sheepishly.

I knew it was all bullshit. I spread her legs apart and I brought my dick to her opening. I slowly entered my sister's pussy.

"Oh fuck!" She cried out.

I pushed in all the way and held my dick in place. I could feel my sister's muscles gripping me hard. She needed this. I began to go hard. My balls slapped against her ass cheeks. Kay screamed as I gave her all eight inches of my fat cock. To be honest, her body was jiggling all over the place as I fed her every inch of me.

"God, don't stop Ben. Go harder!" She told me.

I thought I was going hard but I tried to pound her pussy even more. We were getting into a nice rhythm. Kay would push back onto my cock every time I entered her tunnel. I reached down with one hand and started to pinch a nipple. They were large and pink and Kay got into having me play with her flabby tit.

We probably fucked like that for a good half hour. I was trying to hold back but Kay really had me worked up. I know I should have asked but I had to give her my cum offering. I grunted a few times and then showered my sister's pussy with my seed.

Kay's face said it all. She wasn't expecting me to dump my load into her pussy. My sister squeezed me tighter and I shot more of my cum into her body. It just felt so good giving Kay my hot cream. We carried on for some minutes and then I felt myself getting soft.

I pulled my dick free and my cum came spilling out of her hole. Kay's body was shaking from the fucking she just took. We were both panting afterwards.

"I shouldn't have let you cum in me like that," she said.

Well it was too late for regrets. Kay got up and rushed back to the bathroom. After a few minutes she came back. Her face was all flushed.

"I haven't been fucked like that in a long time," she told me.

I guess we were both still pretty horned up. I led her back to my bedroom. I got onto my back and Kay mounted me. She easily slid down on my shaft. We got into it once more. It seems my sister just couldn't get enough of my cock that day. She rode up and down my rod as I continued to thrust up into her fat belly.

This time I massaged her tits with both hands. I soon found out that tit play was a big turn in for my sister. She later said she had five big orgasms that second time around. I even managed to give her more of my cum. Kay collapsed onto my chest as I finished her off by leaving my cock inside her pussy.

"I suppose you are going to want to do that again?" She asked me.

I was going to want my sister again but we were finished for one day. Kay said she had to get back to her cheating husband. Actually my cock needed a rest. My sister got cleaned up again and dressed. She kissed me as she went out the door and said she would call me later that night.

Sure enough around midnight my phone rang. Kay said that she was all fucked out. Ray was asleep but she was out in the living room touching her pussy. Kay said she still could feel wads of my cum inside her worn pussy. We talked about hooking up again very shortly.

It ends up that Kay will slide over to my place when Ray is out of the house. My sister is a real cum freak I have come to find out. She rarely ever leaves without getting a couple of loads of my seed for her tummy. I have even taken her ass with my cock. Kay is damn tight back there but I seem to have loosened her backdoor up.

My sister screams her head off when my thick cock enters her ass. She loves anal almost as much as taking it in her pussy. Thankfully my sister is on birth control pills. However I do tell her I am going to seed her and give her a big belly when my dick is buried inside her the whole way. After we finish she has told me that when I talk like that she sometimes wishes I would impregnate her.

We have decided to put that kind of thing off for the time being. Kay has even begun to lose some weight. She isn't doing it for her husband but to keep me excited about fucking again and again. For the future I don't need to look for any other women to be my lover. Kay needs as much cock and cream as she can get from me.
