It all began by accident. The day would leave a mark in my psyche forever. I remember the day as if it were yesterday. I was standing next to my sis in the hall of my parents house. We were really close back then and did virtually everything together. What we would do that day would change the course of our adolescent lives.
My sister was very developed for her age. As we were standing near one another for some reason my sis got the urge to reach over and grab my cock over my shorts. I was rather shocked by this, and instinctively reached over and grabbed the first thing that came to my mind, which were her beautiful C cup breasts. Surprisingly, I enjoyed touching them and felt them over her top. We touch each other off and on for days, and found any and every reason to spend time with one another. It wasn't until about a week into teasing one another that we decided to reach beneath the clothes.
