Guys with sisters...how did you find out she wore thongs?

[spacecrate]

I believe my sister started wearing thongs in middle school, but the first time I noticed was high school. Her room was always messy. I walked in one day and there were probably half a dozen thongs all over the floor. Ever since then, almost every time I see my sister, she's wearing leggings with a very clear VTL, or she has a whale tail sticking out. Anytime I say something about it, she just brushes it off and says she doesn't care.

this is so hot! love messy girls that leave thongs out!

So I notice my sister probably when we were in High School. She’s 3 years younger and I was already into snooping for panties, between her and my mom, I had found some cute VS panties and was shocked when I finally found a thong.
My question is now that a bunch of years passed since you found out she wears them, do you find it hot / sexy if you see your sister wearing a thong now?

Not my actual sister. I know she does sometimes but I find it hot with my step sisters and sister in laws

I'd love to snoop through one of my SIL draws but there is always to much family in the house and the floor boards always make a noise all over the house
