The first time I thought of my sister sexually was when we were in our early teens. We used to wrestle all the time as kids. This particular time, we were wrestling on my parents bed. My hand slipped inside her pyjama top accidentally and I cupped her budding breast in my hand. She looked at me but didn't say anything.
Later on, when we were older and attending high school, I would turn the blinds in the bathroom so that I could look in from outside. I would watch as she got out of the shower, nude except for a towel around her hair. Her breasts were now well developed. They were beautiful. I would watch them hang as she bent over the sink.
In recent years, I masturbate with her panties when I stay with her. I was there a few weeks ago, and took some vids and pics of myself masturbating with her panties. I looked through her hamper and found some of her recently worn panties. They smelled and tasted amazing.
My sister is beautiful and I would love to sleep with her. My cock is rock hard as I type this.
