NO.1 Sister-based idol beautiful girl'Lucarina' challenges the role of four slightly naughty sisters of different types! !! A serious and solid eldest daughter, a squid S-type GAL second daughter, a nerdy third daughter who speaks Kansai dialect, and a lively and short-haired fourth daughter. "You can promise not to tell anyone, brother?" This is an incestuous love & SEX drama in which four sisters who are too lascivious approach their shy brother. A must-see for my sister Moe Mania! !! !!
