Even after becoming co-ed, my female classmates habitually lift up girls' skirts to greet them, so in the morning, I can see girls' panties all over the place! They notice my gaze, get embarrassed, and start getting angry. As a countermeasure, we decided by lottery who could lift skirts, and I won! Enjoying skirt-lifting with the girls' approval! Plus, I got confessed to and even had sex!
