When I was young around the age of 8 my older sister use to play with my penis and dry hump me. She was 12 at the time. I enjoyed it and years went by and when I was in middle school and she was in high school she would around me in her panties n only a tank top no bra. I have seen her breasts many times. She had nice 34b caramel colored breasts. I never made a move to do anything with her but I always wanted to fuck her and especially eat her out. I was afraid of rejection n now I look back and regret not trying. Though now I'm not attracted to her now that we are much older she's married with kids n I'm Married as well. Now with my younger sister. There's a bigger age gap and I never saw her as sexually attractive. Until one day when I went back home after being away for a few years. We were randomly talking on the bed n she began to caress my cheek. I got so hard n I wanted to fuck her. She's now better looking than my older sister. I do fantasize more of my older sister n will never forget sniffing her panties n masterbating with them. Rubbing her vagina scent on my penis. Man her pussy smelled so sweet. I haven't smelled a better smelling pussy than my older sister. If the opportunity arised with either sister... I would definitely take it and make the best of it.
