Even though the girls in my class have gone to a co-ed school, they still have the habit of flipping up the girls' skirts to greet each other, so I can see their panties all morning! They notice me looking at them and get embarrassed but angry. As a solution, I drew lots to see who I could flip up their skirts with, and I won! I enjoy flipping up girls' skirts with the girls' approval! What's more, they even confessed their feelings to me and we had sex!
