Warning long post ahead.
Well unfortunately I don't have a sister, but I do have a cousin that wear thongs. She is now in her late 20s, but we have to go back to the early 2010s. Back then I was in middle school and she was in college. So I was sent by my parents to live with my uncle during the summer vacation. It was the first time I ever met his family, let alone live with them.
It goes without saying that as a home-staying guest, I had to help with the household chores. The first signs were the thongs of different styles I keep on finding in the clothes basket. It was the first time I came close with these sexy undergarments so I spent quite some time studying them. Most were just your usual thongs of different colors, however some were quite unique, such as a Hello Kitty-patterned thong. My favorite were the g-strings. They were all so tiny it was a mystery how my cousin was able to fit in them.
Well the day that I saw my cousin wearing a thong was one day when my cousin took me to pick up the family cat from the salon. She was wearing a t-shirt, white low rise jeans that were super tight and a pair of Vans. Throughout the car ride I could see the side of her exposed hips and ass, and more than half her ass was poking out of her super tight jeans. In fact her jeans were so low much of her bare butt cheeks were touching the car seat. Her shirt was also too short, with much of her hips and lower back also exposed. Yet the highlight was the pink waistband of her g-string. Instead of the waists or hips where g-strings are usually worn at, her g-string was worn super low on her buttocks.
Initially I was going to check out her butt when we left the car, but unfortunately I had to retrieve our cat's cage from the trunk. She opened the car's trunk from the driver's seat, and by the time I was ready, she had already gotten out of the car.
