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 a...d 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. We sitted on the couch next to each other .we talked a little then he started to kiss my lips so softly and waiting my reaction.i liked it so much so he invited me to his bedroom. i laid on his bed and we started kissing then i take off all my clothes and so was he . he had a great ass and huge shaved cock. he start to suck my cock and i enjoyed it so much it was my first time . i thought that the next step was to put my cock inside his ass and fuck him but he surprised me when he stood up on. She’d not said anything about it, or repeated the incident since. He shrugged it off and headed to his room.There was a knock and Amanda walked in, James frowned but kept his thought to himself as she closed the door.“So?”“So?”“How did it go,” she asked.“Well.”“You got lucky?” She grinned, her innocent tone betraying her clearly devilish intentions. It was stated as a question but also a statement at the same time.He frowned, “A gentleman doesn’t kiss and tell.”“No?”“Manners maketh the man,”. ..oh how I wanted to stick my face between her cheeks, I was getting hard of the thought and was desperately trying to control my cock at that same time!!!. We had our coffee and talked some more and on the way to her place we were talking about what movies we like and found out that we both love horror flicks....I told her that I had them all on my hard drive we were going on and on and then I asked her hey why dont you come over and we could watch one she looked a little unsure but them she.
