To start off, I never thought of f**king my older sister and didn't even have sexual thoughts about her. I was always curious about her pussy and tits as I saw her mature into a great looking girl. I grabbed a peak whenever I could. She was a beauty with a wonderful figure. Very popular in school and smart. Also, she was on the cheerleading team in high school.
I began exploring things sexual and was well into masturbation when I was 13. My sister was 3 years older than me.
One day when I was home alone and wanted something to trigger an orgasm, I saw a pair of my sister's panties along with other clothing on her bedroom floor as I walked past her door. I crept into her bedroom and picked up the panties and put them up to my nose. They were still damp as she had just changed and rushed out of the house. The fragrance was the most sexiest feelings I ever experienced. I immediately felt it in my crotch as I breathed in the aroma. I took the panties to the bathroom and jacked off with the them tucked under my nose. When I came I pushed the panties over my cock and spurted into the damp part with one of the best orgasms ever. Embarrassed, I returned the panties to my sister's bedroom floor hoping she would not notice anything, although I knew I was hooked.
My smelling my sister's delicious panties went on until she went to college in another part of the country. Whenever she came home during breaks, I was right there waiting for her wonderful panties. I was never disappointed.
She eventually graduated in medicine and went to med school and became a doctor. I went to college and after a couple of years, took over the family business.
While she was interning, my sister got married and at the wedding I had the chance to dance with her both of us well into the sauce. She looked more charming and beautiful than ever. While we were dancing, she asked if I missed her while she was going to college. I told her I really did, not only because she was always nice to be with around the house, but I missed her panties as well.
Then the lighting bolt: 'did you miss me or my panties?' she asked looking me straight in the eyes with a slight smile. I turned a crimson red I'm sure as we danced. I had no idea she knew I was using her panties. I couldn't even deny my actions and felt very guilty. Then she reassured me my secret would be well kept then confessed that when she found out what I had been doing, she purposely left her panties on the floor. She also confessed that she often masturbated in them for extra dampness. She admitted feeling quite sexy that she could turn someone on without being present even if it was her brother.
I think she will make a warm and compassionate doctor.
