When I was 18 I thought these were the dirtiest thing I had ever seen, and I jerked off countless times to these loops waiting for the guy in one of the adjacent stalls to stick his dick through the ragged cloth with a hole in it separating the stalls. Then I sucked him off. Those were the days.
I'm proud of her and if she was sucking my big black dick, she and her parents would be even prouder. I'm sure her mom asked for some of that black dick too.
