My parents were divorced when I was 4. My dad remarried. First year in high school he would ask me to house sit when they went out of town. I knew he wore thongs because I would see them in the laundry room. I did what most teenagers would do .. I started exploring his underwear collection. He had a lot of basic white briefs but in the back of his drawer were a bunch of thongs. I started trying them on. I instantly got an erection. Something about the first time trying them on was such a turn on. Of course being a teenager I would get an erection if the wind blew. He had many colors and patterns of thongs mostly all spandex. I would spend the entire time at his house in just a thong. One time I left a thong on the floor in the bedroom. My step mom made a comment to me about my dads underwear. I was a little embarrassed but just brushed it off as not a big deal. I never saw my dad in person wearing a thong but he was definitely the one who got me started wearing thongs. To this day thongs are the only underwear I wear. I'm not shy about showing them in the locker room at my gym either. Of course its all I wear to the beach. If someone has a problem with my thong .. its their problem not mine.
