When I went to visit a friend's house, there were cute younger sisters there! Their skirts were so short that every time they moved, I got excited seeing glimpses of navy blue fabric underneath! Noticing my gaze, one of the sisters smirked and said, "Too bad! These are bloomers to prevent panty flashes!" and lifted her skirt to show them off, which was irresistible! I even had them put on gym clothes and fucked them!
