When I went to a friend's house to play, there were cute younger sisters there! Because their skirts were short, every time they moved a little, I could catch glimpses of the dark blue fabric, and my heart raced! When the sister noticed my gaze, she grinned and said, "Too bad! This is a bloomers to prevent panty flashes!" and lifted her skirt to show me the bloomers, which was unbearable! Even in their gym clothes, it was naughty!
