My sister was on a terror. Mom and dad left and it was up to me. Thanks guys. A whole weekend of this s***. She’s 12. I’m 16 and stuck with this s***. Alone. After I had had E FREEKEN NUFF I smacked her. She fell and I straddled her to hold her down. We cussed and fussed at each other then I grabbed her b**** and kissed her full on the mouth. It was only a three count till she started kissing me back. She actually did have b****! Holy crap I was making out with my sister!!! Without much thought I helped her up and took her to her bedroom and undressed her. She was beautiful. As I undressed and lay her down, She told me that she loved me. It was almost unreal. She seemed like a princess and I her Prince charming. I had been with 17 girls, both younger and older by then, 3 full fledged women. I used everything that I knew to please my younger sister. It was wonderful. For years it was wonderful. Years ago but not forgotten. We still french when we can in family settings.
