My older sister Darci is 5 years older than me and our mother and father married met each other and married when we were younger. Prior to turning 13 I didn't really have much of a relationship with Darci as we never hung out and I was always scared of her and I was quite shy. She never really spoke to me and when she would babysit me when our parents went out the only words I think I ever heard her say were things like the food is done and it's bedtime little boy. I was always quite small for my age and she was quite tall. Shortly before my 13th birthday, we were making brownies together and I accidentally brushed up against her butt and was scared she was going to hit me thinking I did it on purpose. She looked down at me and I looked up at her and I smiled. She gave me a weird stare and just went back to working. I kept doing my part and she went to her room and I went to mine after they were done. I asked her mother why doesn't Darci ever talk to me. She said it's probably because I am very shy and don't talk to her. I felt like I was a stranger to her ever since we moved in together. Her mother was very loving and accepting of me from the beginning as if she was my birth mother. The night of my birthday Darci picked me up from basketball practice and asked if I was excited about my birthday and I replied with yes. We got home and I went inside and my mother and father were there getting everything ready. They called me down to sing my happy birthday and Darci participated enthusiastically unlike from before. I always thought she was pretty but she had a particular glow to her that day. After they were done I got big hug and a kiss from her on the forehead. With the hug she smothered me with her boobs. I suddenly got a lot more appreciation for her. As time went on we got closer and closer. When I was 15 we were on the couch watching a show and when I fell asleep she scooted over and held me in her arms. When I woke up she was cradling me and the she kissed me on the lips. I started having more feelings towards her as I got older and I started sleeping in her bed with her. The most we did while I was a teen was kiss, cuddle, and I would give her foot rubs and worship her feet. Today I'm still shorter than her by about 9 to 10 inches. We still participate in the same old stuff but we have never done any type of intercourse. I really want to do things with her but am afraid if she rejects me.
