Pool Party Pantsing

I was at a pool party talking to a bunch of people from my school (one of them was this really hot guy I had a crush on) when I felt like someone was standing right behind me. All of a sudden, I felt someone grab the waistband of my bikini bottoms and pull them all the way down to my ankles. I wasn’t wearing anything underneath, obviously, so everyone saw my butt and vagina. I was so shocked that I just froze for a second before I pulled my bottoms up. I didn’t even know the girl who did it and she said that her friends dared her to. It was probably the most embarrassing thing that happened to me in all of high school.
