I guess my story is not all that unique, though to me, being his sister, at the time, was the most incredible experience I could imagine. My brother Todd was the type of guy everybody noticed, he was a big, strapping, six foot three inch, two hundred twenty pound athlete. Todd had just turned nineteen that spring and even though I was much younger, I had become keenly aware of his masculinity and amazing physique. I was very interested in the male body which made seeing my brother grow and develop an all encompassing fascination.
One afternoon, our parents had gone to the wedding of a family friend so Todd and I spent a lazy day at home. I really liked it when Todd would wear short sleeve shirts because he had the most sexy, muscular arms! That day I made it a point to say something to him about his build which had been constantly on my mind for months. He really responded in a favorable manner to my questions and soon took his shirt off so I could get a really good look at his arms and his very wide shoulders. The next half hour or so was spent with me exploring my brother's beautiful muscles while he proudly flexed them and displayed them for me.
I will never forget how incredibly excited I was as I ran my hands all over his chest, back, shoulders and arms. I even took it upon myself to put my nose on his nice, fair skin, I just loved the way his body smelled! Todd then asked me if I wanted to see the rest of his body which actually made me tremble with excitement. Those were the very words I had been fantasizing about hearing from him for the last year or so. He then stood up and began to take his pants and briefs off. I sat on the foot of his bed as he stood in front of me making a very sexy display of himself. I began to run my hands up and down his muscular, hairy legs still quivering with excitement. Todd's penis was large and flaired out to a very wide head. His balls were also big and heavy. I loved the very thick, dark bush of hair above his cock. I continued to touch his legs and butt as he began to show me how he played with his cock. I watched him continue to massage it up and down while I kept putting my nose in his thick bush which excited him more.
Within a few minutes, my sexy big brother was having a very intense ejaculation in front of me! I couldn't believe how much sperm squirted out of his pee hole! He ended up doing it again for me a little later that day and I was never able to fall asleep that night thinking about it and replaying the day over and over again in my mind. Todd and I became very close the rest of that year as he continued to let me enjoy his wonderful body. By the time he went away to college, I was able to jerk him off very well and we both would enjoy the excitement of his ejaculations. This only happened a few more times while he was in college, we are now both married with our own families but we secretly cherish the memories of those incredibly exciting times we spent together.
