Shocker

my confession is masturbation related, but as you will see it grew to something much more. I started masturbating when I was 12 years old. I have a sister named Chris who is four years older than me. though at 12 I had never seen her naked, I did see her in panties and bra on several occasions and she was the subject of some great fantasies that I had. the summer I turned sixteen, Chris came home for the summer from college. Even though she was my sister, I thought she looked hot. the first night she was home, I jerked off into a pair of her panties that I took out of the laundry. it was so horny, I stayed hard and continued to jerk off and came off again in her panties. I woke up after nine in the morning,and my mom and dad had already left work. I came down to the kitchen in just a pair of jogging shorts for breakfast and was still horny from the night before. I heard Chris coming down the stairs and she walked into the kitchen wearing a see through bra and a pair of thong panties. I could not help but to stare at her, I had never seen her nipples before and thought they were beautiful. I also realized she had shaved her pussy because I could see right through her panties, she said I and opened the refrigerator to get some juice. Her ass was completely exposed except for the thong. I got a hardon and was glad I was sitting down and she could not see it. she started reading the paper at the table and I said I was going to get dressed. when I got to my room, I took of my shorts and starting rubbing my prick. It felt great and all I could think of was Chris's body. I was on top of the covers, stroking off and just about ready to come off. at that time Chris knocked on my door and immediately walked in and caught me. She was still in her bra and panties and asked if she had made me horny that morning. I said she did and kept jerking off in front of her, when I came, it squirted all over my legs and stomach. My hardon was still pointing straight up after I came off. Chris took of her bra and panties and laid in bed with me. she took over stroking my cock and when I told her I was going to come off again, she put my cock in her mouth and sucked me off. we spent the rest of the summer in each others beds, almost every day that our parents weren't home. at the end of the summer she went back to college and we have not had sex with each other since. We are both married now, but I still fantasize about fucking her doing a 69 and coming in each others mouths
