My younger sister

My sister was very well endowed at the age of 15 and had Beautiful soft silky long hair down to her waste that I always loved watching her brushing her hair. One day we went to the beach on a warm summer day to swim, when we returned to the beach she asked me if I would brush her hair for her. It was something I had always fantasied about doing doing for years. As I knelt behind her and began brushing her Beautiful long hair I became very aroused when she turn turn and notice my erection in my swim trunks. I got so scared that I jumped up and ran into the lake not knowing what was happening to me. She came in after me and ask why I got so freaked out, I said I was so embarrassed and scared that she might tell our parents. She just smile and said it's okay and took my hand and lead me back to the beach and handed me her brush and said your not finished brushing my hair. I was so nervous that I might get another erection again. I knelt behind her and continued to brush her Beautiful long hair till it was so soft and silky I could resist pulling her hair into a ponytail and brush my face with her soft silky hair which aroused me again. She turned around and kissed me and toke my hand said lets go down that to old run down boat house I something to show you. I wasn't sure what was in that old boat house that I haven't seen already, when we stepped inside she removed her top and turn to me and smiled saying do you like what you see, I could barely speak. She then laughed and said touch them if you want, my hands were shaking as I reach out to touch them. She said don't be scared it's okay I want you to feel them. Then she put her hand on the back of my neck and pull my face to her firm tits and suck my tits I know you want too. As I sucked on her hard nipple I was so aroused then she reached down and pulled my trunks down exposing my rock hard cock and then grabbed my cock while I continued sucking her tits. And before I knew it I was shooting a huge load all over her leg. Then fear came over me and was unable to ever speak or even run away, with my cock still in her hand dripping cum she said don't be scared know one will even know it's our secret. Then she raised her hand to her mouth and licked all my cum off her fingers then she kissed me I got my first taste of cum, then she pulled away and said did you like the taste your cum, which I said yes. We then got dressed and return to our spot on the beach when she asked if would like to brush her hair some more I was more than welling. She said I loved having me brush her hair and any time we were alone I was allowed to brush her Beautiful soft silky long hair. From that day forward I was so attracted girls with Beautiful soft silky long hair. But my sister was always willing to indulge my fetish up until I left home and join the Army.
