My little sister Rachel has always looked up to me. Even today, with her being 19 and me 23, she still looks to me for protection. I knew by the way boys would chase her around that she was attractive but she was always my little sister until one day.
I live by myself and Rachel would come over to stay the weekend with me every now and then, just to get away from our parents. Even if my girlfriend was over, she'd still stay over. She came over after going on a holiday with our parents and her boyfriend. She was eager to show me her pictures from the trip. She went through the pics quickly and I didn't get to see them well.
Later than evening, she was going to shower then go to bed. I asked her if I could see the pics again so she threw me her phone and went into the bathroom. I looked threw the pics again and was about to put her phone down until I saw a folder with bf on it. I clicked on it and was shocked at what I saw. My little sis had grown into a woman. I saw pics of her standing in a bra and panties sets, her ass in thongs and her hands covering her small breasts. The more I scrolled, the more revealing the pics. Her naked ass, her small breasts with big nipples and her perfect looking shaved pussy. I knew it was wrong to be looking at them but I couldn't help myself. I could feel that my dick was as hard as a rock. Before I knew it, I was texting myself pics of my little sister. After the pics went through, I deleted the text messages. I put her phone down and tried to get my hardon to go down.
Rachel came back out into the living room wearing a tank top and short shorts. I looked at her in a different way, not as my sister but a beautiful, sexy woman. I could see her nipples sticking out under her tight tank top and when she walked by, her ass cheeks were slightly out of her shorts. What little my hardon went down, it was back up. She sat beside me and cuddled up to me. I was going crazy. I know it's wrong but I just want to touch her, to feel her soft body but I didn't. I tried to move away from from her but she kept getting closer.
I had to get her away from me. So in a brotherly way, I pushed her away. She thought I was playing so she pushed back. I told her to stop but she kept on. We kept pushing each other until she climbed on top of me. Her small breast grazed my face as her tight ass fell on my lap. I was as hard as ive ever been and I knew she felt it. After she bounced down onto my lap, she stopped and went, "oh." I swear she grinded on me for a quick second. I grabbed her under her arms and threw her onto the side of the couch we were sitting on. I got up and told her I was going to bed.
I went into my bedroom, both embarrassed and arroused. I tried to calm down but I couldn't. I couldn't get Rachel off of my mind. I hear her say good night and the other bedroom door close. My erection was hurting me so I decided to releave my tension. I grabbed my phone and looked at one of the pics of Rachel naked. I could see her pussy and small breasts in the pic. I bet I came in 10 seconds. I cleaned up then tried to sleep. All I could think about was Rachel and what happened earlier.
