If her legs were shaking, she may have had a vibe or eggs or something inside of her while dressing all slutty for you. Shame you couldn't have caught up and groped a bit to see how she reacted.. Nicely spotted though; keep an eye out!

Yeah I was going to walk behind her and film a little clip but oh well
That was a very slappable ass. I rarely see women wear shorts that tiny, she's probably one of those horny ones who gets turn on wearing that and knowing guys are staring and getting hard.
