I was still living at home with my parents and my eighteen year sister Beth. It disappointed me that I was twenty one and still under my parents roof. I didn't have any sex life to speak of. There were plenty of times I had eyed my sister. Beth had brown hair, she was thin and had small tits. Often times she didn't bother wearing a bra around the house.
It was a Saturday and my parents were away visiting friends. It was just Beth and me. I was in the living room watching TV. I looked down the hallway and saw my sister coming out of the bathroom with a towel wrapped around her body. I couldn't control myself. I got up and walked down the hall. I took off my shirt and shorts I was wearing and let them drop to the floor.
I knew if I opened her bedroom door things would changed drastically. I didn't knock. I opened the bedroom door and there was Beth standing there naked.
"Chris, get out of here!" she shouted at me.
I had no intention of leaving. I walked inside and stood right in front of my sister. I saw her eyes darting to my cock. I am around eight inches in length and my cock tends to hang down. I could see that Beth's nipples were rock hard. I had to act.
"I have been thinking about you for the longest time," I told her.
I stepped even closer and placed my hands on her chest. Beth let out this sigh. I lowered my face and took her nipples in my mouth. Beth lost her composure. She threw her head back as I got her aroused with my mouth. I took my one hand and rubbed it across her crease. Beth was wet down below. I wanted to do more than just touch my sister's body. I pushed her down onto the bed.
