The little devil gal sister "Sora" who became a girl's school student is very interested in things that are dirty! I started to study Confucianism in order to seduce my favorite youta (brother)! If you find your way anywhere in the house, you will approach with too much jealousy! You can intrude into the bathhouse, dive into the bedroom, or invite me to your own room with a casual look! My brother ... I want to breed my sister or it's a real pervert ♪" While provoking in Gal language, I can drown in the sex that I just remembered!
