When I was in high school in the late 90's, one thing that used to drive me crazy a lot was the dance/drill team at our school. Here in Texas, they are very popular and usually perform at halftimes of football games. A lot of them wear very sexy outfits when they perform.
At the football games, the girls would wear hats, gloves, their outfits with very short skirts, and white boots. The thing that would drive me nuts were the tan dance tights they wore with them. They were shiny and looked a lot like pantyhose. They always made their legs look very smooth and tanned and sexy. The combination of the short skirts with their legs and white boots were sometimes too much. Other teams around the area wear basically the same type of outfits too.
I went to another school's game once and sat at the end of the stands. It was a couple of minutes before the game started and their dance/drill team came next to the stands where I was. Those girls in those outfits looked incredible. Then I saw a couple of them adjusting their leotards under their skirts. They looked so sexy hiking up their skirts from each side to reach their leotards to fix themselves. I already had a hard on at the time and seeing this just made it worst. They usually just fixed the back of their leotards to fix their wedgies (I think) but then I saw one girl reach to where her crotch was and fix it there. Just the way she was standing slightly bending over in that sexy outfit with those sexy legs was so incredible. I was wearing tight blue jeans so it didn't help matters at all but after seeing that it became too much and I actually had an orgasm in my pants. I was there with a couple of family members but they didn't seem to notice anything. I tried to make it as least obvious as possible and apparently it worked, although I was a little shocked because it had never happened before. This experience alone would give me a raging hard on for a couple of days afterwards.
During the week, I would see some of the girls around campus after school doing various things. I would see them in maroon jackets(school color) and black tights with black shoes. Seeing them in those black tights would drive me nuts. I remember following some of them just on purpose to see their gorgeous butts move under those tight tights. Other times, I would see them in small tight bike shorts with those shiny dance tights underneath that resemble pantyhose. They looked so sexy and would frequently give me hardons as well so I usually went home right away to masturbate.
The only thing that would suck was these girls were kinda stuck up and conceited so I never talked to them plus not all of them were total knockouts either. Although I obviously didn't mind looking at them in those sexy outfits.
I have a couple of more stories similar to this from high school but I'll save them for later.
