My step-sister Sara!

Note: This is my first story so it probably won’t be the greatest and I am happy to receive comments or PM about how I can make future stories better, if this story turns out horrid then it might be a while until I decide to try writing another, Thanks!


Hi, I am Ryan, I am 16, have dark brown eyes, dirty blonde hair, I’m 5’ 11”, but the best thing about me is my 7 inch dick, I am still a virgin but I didn’t know that it all was about to change. Well, enough about me and on to my step sister. Her name is Sara, she’s 17, is 5’ 8”, has blue eyes, bright natural blonde hair, B cup breasts and she has an amazing tight ass that jiggles ever so slightly when she dances around the house. I know I shouldn’t be paying too much attention to her because she is technically my sister, but what the hell; she is so hot it would be a crime not to notice.

It all started after dinner one day, I was doing my homework, stupid Math, and I was having some trouble with my calculus and since Sara is in grade 12 I thought she might know a thing or two more and could help me with this damn question, so I walked out of my room to look for her and see if she could help, I thought that she was in her room (which is the room next to mine), music playing, with her door closed completely, I thought this was strange because it is normally kept open.

I didn’t think too much of it so I decided to just go ahead and open it, when I walked in I noticed her laptop was just lying on her bed with the screensaver going, but she wasn’t there, so I decided I would see what she was doing on her laptop and wait until she came back, when I touched the mouse pad the screen turned on and showed a full screen porn with a man tit-fucking a sexy young woman, I was really surprised because Sara didn’t seem like the type of girl to be watching that type of porn, or porn at all!

Without thinking I hit the play button, pulled down my pants and started jacking myself off to the porn, a few minutes into stroking myself I heard the toilet down in the hall bathroom flush and I suddenly realised that she was walking down the hall so I quickly stopped jacking off and set her computer back where it was but I was worried because the screen was still on the porn.

I quickly stood over by the wall on an angle that I couldn’t see the screen. She noticed the room door was open and that I was in there and she quickly ran over to her computer, but when she saw the computer was on she had a worried face and quickly closed it.

She asked “Ryan, what are you doing here? My room door was closed because I didn’t want anyone in here.”

I replied “I need help with my calculus homework; I can’t seem to solve one of the problems.”

“Okay, fine, I’ll help you with it, but next time please don’t come in my room without me being here.” I noticed that when she said that she happened to notice my still raging hard-on and she made a strange face then opened her mouth to say something but quickly shut it and walked over to my room with me.

While doing my homework my boner just wouldn’t go down, I just couldn’t stop thinking about how my step sister was watching porn and I almost got caught watching it in her room.
