I was 14, my sister was 17, she would leave her underwear laying about, she had some thongs that I found interesting and wondered how I would look in them. I was two scared to try them on though. Fast forward a year my sister moved out and left some of her underwear behind several thongs and a gsrting or two. My curiosity finally overcame my apprehension of trying them on. So I picked out a black thong with a rainbow waist band made of a stretchy material. I tried them on when I was home alone, and decided that i liked the way that I looked in them and how the felt on me. So i decided to keep them, and still have and wear them to this day.
