My name is Roger and I live at home with my parents and my eighteen year old sister Kate. I hate being twenty and still living at home, but I can't afford to leave right now. One good thing about living at home is my sister. Kate and I have always been close and I think she has a thing for me. I have never tried to find out until recently.
I had just woken up one morning and I heard the water flowing in the shower. My parents had gone to work so Kate had to be cleaning up. I sat up on the side of the bed. I had a morning boner and I stroked myself for a few minutes. I'm not sure what got into me, but I headed towards the bathroom. The water had cut out so my sister must have been drying off now. I didn't bother to knock, I just barged into the bathroom.
My sister was standing there naked and her eyes went wide.
"Roger, what are you doing in here, get out!"
I wasn't going to leave. I eyed my sister's body. Kate had small tits and her nipples were all hard right then. Her bush was light brown and it looked like she had it all trimmed up. I could see Kate fixing her eyes on my dick. I am nearly eight inches in length and my dick was dripping with precum that morning.
I walked directly up to my sister and I pulled her towel away. I wasted no time pulling Kate into my body. To my surprise she didn't really fight me. I planted my lips on hers and we kissed. I told my sister that I needed her. Kate just whimpered a bit. My hands went to her nipples and I rubbed each one with my fingers. I could tell that was really getting to my sister. I managed to get Kate to turn around facing the vanity. I lowered my hand to her pussy.
I slid my fingers across her wet folds. Kate was moaning now as if she liked everything I was doing to her. A few minutes of touching Kate's pussy and I told her to lean over the bathroom sink. I don't think she was ready for what I had planned, but she did it anyway. I spread my sister's legs and pulled her cheeks apart. I took hold of my raging cock and I fitted my mushroom into place.
