I was 11 when my curiousity about my 16 yr old sisters panties got the best of me. I had to know what it felt like to wear a pair of my sisters sexy panties. I liked when I would see them in the laundry room, or when i looked thru her underwear draw to view her collection of sexy panties. After school, I'd always be home alone with my parents working and my sister at cheerleading practice. At first I would pick out a few of her sexiest pairs and put them on her bed so I could masturbate to them. Then I wondered what it would feel like to try on a pair of her sexy panties. My curiousity led me to try on a pair of white nylon Maidenform panties with lace front. It felt amazing when I slid those panties on as they got me so friggin horny. I've been secretley wearing panties ever since that day. I'm curious to know the age when other guys 1st tried on their sisters panties ?
