When I was younger, my year older sister had her wisdom teeth removed. She was in lots of pain and required medication to numb the pain, and medication to help her sleep. One evening she asked for her pills from my mom and settled in for the night. My mom had asked me to sit with her until she fell asleep, to make sure everything was okay.
Eventually the medicine kicked in and my sister was totally asleep. I immediately pulled the covers now to expose her and catch a quick glimpse of her girl parts. I figured what was the harm. As I was looking at her in her pj's, I wondered what her pussy looked like. I gently pulled down her shorts and almost blew my load when I saw her hairless pussy. Such a sight. It was beautiful.
At this point I reached for my cock and started to jackhammer my dick like there was no tomorrow. With a mighty thrust, I blew my load all over her belly, the first string actually hit her in the hair on her head. It was magical.
After that, I could never look at my sister the same way. We have had several encounters through our childhood and I will be telling my tales.
