She was sitting 2nd row in class on the furthest right vertical line of desks. I was sitting one row to the left, 3-4 desks back, a perfect angle. She was wearing jeans and it was a solid 3-4 inch whaletail. She never reached back to check ever. Nobody else said anything although I’m sure others mentioned.
I double checked any chance I got to see another. Sadly dont remember any others. Knowing what I know now it was hard not to WT in that era. I have a tight pair of athletic pants and just by the way they are whenever you bend over its a WT machine, like constantly. Girls with a big booty dont stand a chance in those!
I do remember asking a close friend in HS who was a girl what she wore under different clothes. She was aware of panty lines and did avoid them. I had another female friend who wore just a thong under a sundress and while I’m not into them myself, that must feel so free, naughty, and fun to wear so little out and about.
